145: Owl Monkeys w/ Alexi Grousis!

Ellen: Hello my friends and welcome to episode 145 of Just the Zoo of Us. This week I'm talking with one of the hosts of the We Out Here podcast, a zookeeper and storyteller who's joining us to talk about a unique and mysterious creature bouncing around rainforest canopies by the light of the moon: owl monkeys. We talk about how owl monkeys have adjusted to thriving in the twilight, what's going on behind those big, beautiful eyes and what it's like to work with these little fluffy forest sprites. Just the Zoo of Us presents: owl monkeys with Alexi Grousis.

[intro music]

Ellen: Hey everybody. This is Ellen Weatherford. I'm here with your favorite animal review podcast, it is Just the Zoo of Us. And this week I am so excited to bring to y'all. Alex Grousis, say hi, Alexi.

Alexi: Hey, howdy, thanks for having me on Ellen.

Ellen: Thank you so much for being here. Can I get your pronouns real quick?

Alexi: Yeah, my pronouns are he him and his.

Ellen: Thank you so much. And Alexi, I know you from Twitter. I think a lot of people who frequent science Twitter have probably seen you on there because you're just about the funniest person in the universe.

Alexi: Ah shucks.

Ellen: Aside from that, you're also an animal professional and a nature story teller. Before we talk about our really cool animal for today. What got you started down this path of like animal and nature fandom, I suppose?

Alexi: Yeah. Yeah. So I was a kid who was lucky enough to have green spaces around the neighborhood that I lived in. Though I didn't necessarily have like forest nearby. My friends and I, as kids would, you know, we'd run around the neighborhood playing spies, which I don't know how many of y'all actually had that game as well, but it really was just a bunch of kids being weird creeps , but we would run around like quote- unquote spying. And then what we would do is we'd also, you know, go into the bushes and go into anywhere where there were things that we could turn over. I had a big backyard. And so this one is actually like horrifying as an adult, but my brother and I would dig these trenches and would make these very complex routes through the dirt, in my backyard, creating like these roads, we, you know, we imagine ourselves like building a city and then we would set the hose up and then would run water through and just watch how the water moved. Really fun as a kid. But keep in mind, I grew up in central California and that is a nightmare for me now as an adult, knowing the water situation there, but.

Ellen: You were just casually terraforming.

Alexi: Yeah, exactly. Just, I don't know how many gallons of water I wasted as a child. And I hope that my mom never connected me to those water bills cuz I'm sure they were a nightmare.

Ellen: You think they were just looking at their utilities every month? Like "I don't get it."

Alexi: Yeah, they had to be like, we had to have a massive leak. That's probably the thing they suspect the most. Not realizing that I filled a three foot, you know, space with just water watching it run.

Ellen: It was just your system of aqueducts.

Ellen: Yeah, exactly.

Alexi: I was a Roman emperor in my smaller was it was irrigation project. Uh, so those were, those were some of my first interactions with like nature and like the physics of the world around me, you know, I love flipping over rocks and seeing what bugs were underneath. Uh, if I had a good log nearby, I love turning it over. Uh, one of those like special memories of growing up in the central valley, which doesn't happen enough any longer, uh, is that every year during the winter, we have, uh, Tule fog that, uh, rolls down the mountain into the valley. And the visibility in that fog could be counted in feet.

Ellen: Whoa.

Alexi: Yeah. It's deeply foggy in that area and is becoming less so with climate change. But during that time in Fresno, which is a very arid, you know, region in central California, you know, you'd start seeing frogs pop up. You know, and I was like, this is the desert. And all of a sudden there are frogs, you know, popping up in my yard because you know, everyone tried to have lawns cuz this is America. Uh, but you know, in some spaces where you just don't wanna have lawns, you just have like these rock gardens or like dirt gardens. And the dirt during those really wet cold periods, the dirt goes from being brown to becoming bright neon green from all the mosses that have laid dormant for the whole year.

Ellen: Oh, that's wild.

Alexi: Yeah. The most beautiful time in Fresno, California, and in the central valley hands down is the winter time. You know, a lot of people don't like the cold, but I'm like, it's the only time where things turn truly green in that area. It's amazing. It's beautiful.

Ellen: I bet the frogs were just going nuts.

Alexi: Aw man. Yeah, absolutely. You know, those like the late winter in that February, March area was like, ah, that was prime frog season.

Ellen: That's so funny. It's the opposite of what we have here in Florida, in Florida in the summer is when, you know, it'll rain for like a good three hours every afternoon. And so in the summertime is when, like at night the frogs are just deafening, like we're right up against a pond. So on summer nights we have to like blast the TV volume as loud as possible. If we wanna hear it over the frogs. Yeah. Cause they're like deafening out there.

Alexi: Yep. Yeah. Having moved down into the Gulf south region, those afternoon storms and like the consistency of them was mind blowing to me. I don't know what people who moved directly from the desert into this place must think. Cuz fortunately I had a transition over seven years in the Midwest, but yeah, those afternoon showers that are consistent here and like deafening. Powerful. It's like a February, March in Fresno every single day.

Ellen: It sounds like you kind of had like a tour of the different ecosystems of the continent going from like the desert to the Midwest to Louisiana.

Alexi: Yeah. Yeah. I, well, I. Not enough. There are so many biomes and ecosystems in the United States that I still have never gazed upon aside from seeing them in like, you know, zoo books or something like that. so, you know, one of these days I'm gonna see it all. I'm gonna treat this like my little Pokedex, and I'm gonna see every single eco type that we got. Uh, but for now I've had a nice little, you know, glimpse of the great Plains. I've seen the, you know, the arid valleys in the central valley. Uh, the cool thing about the central valley is it's at the foot of the Sierra Nevadas so you can slide right up the mountain and see some beautiful stuff up there.

Ellen: Oh, I bet you see the coolest critters.

Alexi: Ah, man, truly, but you know, the, at the age that I was going up there, I was really, uh, I was really focused on running and jumping. And so every critter that was nearby me was, was gone. They, they were in a mad dash to get away from me.

Ellen: That is just simply the backdrop for the parkour, uh, routine that you're running.

Alexi: Ah, Absolutely. And I was a loud child during most times that I would've been able to actually see these animals. So they, they saw me far before I ever saw them.

Ellen: I guess that's probably good for them. Right. That gives them an early warning system.

Alexi: Absolutely. It's a great way to avoid, you know, bear interactions and mountain lion interactions as well. You know, being a little bit loud can actually keep you safe.

Ellen: We should all channel youthful, Alexi joy when we go out into wilderness so that all the critters know to maintain their space.

Alexi: Yeah. Unless you are birding or herping , if you're birding that's not gonna, you're not gonna see anything.

Ellen: Oh, that's true. But so these days now you, uh, mentioned that you are in Louisiana then working with animals, yeah?

Alexi: Yeah, yeah. Yeah. So I work a lot with nocturnal animals and venomous snakes in Louisiana. One of the nicest little gifts I've gotten from nature was I actually saw a wild corn snake while in Gulf Breeze, Florida, a couple weeks back.

Ellen: Wow.

Alexi: Yeah. It's one of those animals. I see them in captivity so often that I don't really consider them a wild animal, even though they definitely are a wild animal. Uh, you know, conceptually in my brain, I just don't register them as such, but then I saw this wild corn snake and I was like, wow, that is an orange animal. That it just was there on the ground in front of me. It was mind boggling. Beautiful. Ah, I love snakes. They're they're wonderful. They're one of those animals that like, if you've ever had the privilege of touching a snake in a situation that was non dangerous, uh, and non-medical inducing, ah, man, that's like stroking the hand of God, you are touching some of something that is so soft and so beautiful and so unique. It's an animal on land that has adapted to having no limbs and having more ribs than you can count. And they're just spectacular, man.

Ellen: Frankly. It's so brave of them.

Alexi: It truly is right. Oh man. Like chin to the ground moving.

Ellen: They're so cool. I feel like it feels soothing. Mm-hmm like, if you get a chance to feel a snake, it feels like the same effect as like a worry stone.

Alexi: Yeah. Yeah. And we see snakes and think that they're slimy all the time, but they're actually very dry, very smooth. I think we think they're slimy because of how shiny they are. That just means they're kitted up. That means they got the good scales. They're clean, fresh.

Ellen: They're lovely, delightful creatures. I could talk to you about snakes all day long because we have some beautiful snakes here in Florida as you do in Louisiana. But today we're talking about a monkey, which I have to admit, you told me the other day that you wanted to talk about this monkey and I had never heard of it in my life. So I'm a complete blank slate! Today, we're talking about owl monkeys. For people listening, who like me are like, what are you talking about, Alexi? What is an owl monkey?

Alexi: So an owl monkey is a spectacular genus. You know, an entire group of monkeys from south America that are almost exclusively nocturnal. And I say almost exclusively because there's one of 'em that is cathemeral, which means it's active pretty much whenever, uh, day, night, dusk, dawn.

Ellen: Just when the spirit moves them.

Alexi: Exactly. When the vibe is right, they get going. Uh, so owl monkeys are a pretty small, very small monkey. They're about as big as an adult human's like forearm, if they're not standing all the way up, they're a little bit taller. If they're standing all the way up.

Ellen: Is that including or not including the tail?

Alexi: Uh, the tail is probably roughly, almost the length of your wrist to your shoulder.

Ellen: Oh, wow.

Alexi: It's a, it's not a terribly long tail, but it's pretty long in proportion to their body, but yeah, they're a mobile little monkey that. Pretty high up in the canopy in the rainforests of South America and a really cool thing about them that makes them also fairly unique among primates is that they are a, what is considered a genetically monogamous species, which means that they tend to form these pair bonds that are able to be seen through their DNA. Like you can track the, um, the family lines and lineages through that. You can see genetic evidence of monogamy, which is pretty interesting. Yeah, you can see bodily structures that represent that, but what's really, really cool when you are first looking at 'em is their massive eyes. Their eyes take up a huge amount of space in their head. And for obvious reasons, they're active at night and they need to see a lot. But that being said, even though they're active at night, it doesn't mean that they prefer the entire darkness because they are a monkey. They do some pretty incredible leaps through the canopy. So they actually, a lot of them we're finding, they are most active during like a full moon. So they're active at the right amount of light. Mm. So that they can judge those jumps. They can see their partners, which is really important. Uh, and they can find food.

Ellen: Oh, okay. So rather than like going all in and being like thriving in complete darkness, mm-hmm, like they can, they can get around well with like a little bit, because you mentioned like a full moon, right. When the moon is full, you're getting a lot of that moon light. So like, it is a significantly brighter night than if you were, for example, a new moon when the moon was not shining.

Alexi: Exactly. Yeah.

Ellen: Interesting. But they don't, they don't like that, like total darkness? Yeah.

Alexi: They don't like the total darkness. They haven't, yeah, like you're saying they haven't fully invested in darkness.

Ellen: A little bit. They stuck their toe in.

Alexi: Yeah, exactly. They're like, I like it a little dark, but not too much. Yeah. And that's because you know, the darkness is while it can be really good for hiding from predators, it also means that you can't see your predators as well. Uh, and a lot of monkeys, like humans also, uh, have very short snouts, so they don't have this incredible ability to smell their predators from far off. Their gen name is aotus, uh, which actually translates. I think that's might be Latin, maybe it's Greek, but it means essentially earless. And it's not that they don't have ears. It's just that they're very fluffy and they have ears that aren't super big. So they look like they have no ears, so they, they can hear fairly well. They can smell kind of well, uh, but one of the senses that they fully invest in is vision. They are not gonna be able to smell their predators from very far off. They can hear their predators decently well from far off, but if you're in the complete dark, it's very easy to get snuck up on.

Ellen: Right. Such as, for example, another nocturnal predator, the owl. I guess I had assumed that they were named the owl monkey perhaps because they resemble an owl. Like maybe they look like an owl, but I'm hearing a lot of similarities with owls as well. Like they, you know navigate using sight at night.

Alexi: Yeah. Yeah. With owls though, owls have pretty good hearing. What's kind of wild, I don't know if you've ever seen an owl's skull, but their ears. You can actually see where their ears are on their skull and their ears are offset. So one ear is typically higher than the other one. And that actually lets 'em triangulate sounds. Some owls, I think like the great gray owl, if I'm thinking of the right one, the feathers on its face, which are very broad, very circular, very round, uh, it funnels the sound into their ears, uh, which is pretty incredible.

Ellen: They got like a dish, like a satellite.

Alexi: They, they lit-- like they literally do. I, 10 outta 10. If you're listening to this part, please look up what a great gray owl looks like. If you've never seen one, their whole head looks like a satellite dish.

Ellen: It sure does. They even have like the banded, like marking going around, like concentric rings that like go towards the, it looks like if you were going to like design a character that was like, based on sound waves, you would design it like this, like giving it like a satellite dish face with sound waves going towards its eyes.

Alexi: Mm-hmm . Yeah. Yeah. And so for the great gray owl, it's looking for prey that is actually under the snow. Uh, so it's gonna be using a lot of that hearing to capture that prey. Um, whereas owl monkeys, the nice thing about them is they're not really looking for prey that moves. Uh, they're looking for fruits, uh, leaves. They're typically herbivores. So their food only sways in the wind. So as owl monkeys travel, they're gonna be looking and they're gonna be foraging as they move. They also, when they're eating, they communicate as they're moving, they communicate as well. Uh, as they travel, they tend to chirp, uh, and they'll not necessarily whistle, but they'll produce small whistle, like sounds. It's a very sweet sound.

Ellen: Aw, that sounds really cute.

Alexi: They're very adorable. They straddle the line between adorable and strange looking and somewhat alien because of the size of those eyes. Uh, and depending on the individual, you know, some individuals are a lot prettier than others.

Ellen: There is also a feeling that I feel like I, as a human being get, when I look at a non-human primate, which is like, at first you're like, oh, cute monkey. And then if you look at, if you like, really look in like their eyes, you start to get this feeling. Yeah. That's like that uncanny valley, like uneasiness. That's like you're a little too close to home for me.

Alexi: Yeah. That's how I feel when the owl monkeys I work with in particular, occasionally when they get surprised their response is to stand all the way up. It makes 'em look a little bit bigger. Uh, I don't like that so much.

Ellen: Can y'all not? I need you get back down on all fours for me, please.

Alexi: Yeah, please, please return to the monkey squat that you do. Uh, they, they actually have surprisingly long legs that give them the ability to leap pretty far, you know, think about a frog, uh, those long legs generate a lot of force and can throw their body a good distance. Uh, I've seen the owl monkeys that I work with in particular can jump as much as three times their body length. Uh, which is pretty incredible. That's like me jumping almost 18 feet. that would be pretty spectacular.

Ellen: Get them on a basketball team.

Alexi: Exactly. Or, you know, uh, track would be awesome as long as they didn't have to run up. Uh, their runs are not very elegant, uh, their feet, if you've never seen what, uh, what monkey's feet typically look like, you know, that primary digit, that toe that we call the big toe it's actually rotated to the side. So their feet are built like hands as well. And they have very long elegant toes and fingers that are good for gripping.

Ellen: It's a toe thumb.

Alexi: No, literally it is a, it is definitely a toe thumb. Absolutely. Uh, monkeys typically want to move on top of branches when they're in trees, as opposed to apes who do a behavior called brachiating, uh, and that means that they're swinging under the branch.

Ellen: Oh, I didn't know there was a word for that. That's cool.

Alexi: Yeah. Yeah. Right. Brachiation lets an ape move quickly, use their momentum as they're moving, but also they can move on branches that might be a little bit smaller that wouldn't support the full, you know, their full body. Uh, so an ape like an orangutan can both walk on large branches on the top and then on the thinner ones that are more handheld size, they can swing from them. Uh, whereas a monkey typically doesn't do that. Although spider monkeys and a few other ones definitely do some brachiation, owl monkeys almost exclusively are gonna be walking on the top of branches unless they're gonna dangle their bodies down to reach something. Or if they're playing, I do see them do a play behavior where they dangle upside down from them kind of like a bat.

Ellen: That's so cute.

Alexi: Yeah. It's pretty spectacular.

Ellen: So if this is your first time ever listening to this show, our, our thing that we do here is that we review animals by rating them out of 10 in the categories of effectiveness, ingenuity and aesthetics. So first up is effectiveness. This is like things that the animal has adapted about their body or like built into their body that let them conquer challenges that they face. Or like do the things they're trying to do. So like get their food, not become food, things like that. Um, Alexi, what do you give the owl monkey out of 10 for effectiveness?

Alexi: Okay. I would have to give an owl monkey in terms of its broad adaptations. It would get a standard seven or eight, maybe a 7.5.

Ellen: Okay.

Alexi: If. If they weren't the only ones that figured out how to be nocturnal of all the monkeys. So I have to give 'em an extra point boost. So they get probably an 8.5 because they did something that not a lot of monkeys could do. Uh, they did the same monkey behavior, but they do it during dark conditions.

Ellen: Yeah. It's an originality bonus.

Alexi: Right, right. You know, they're playing life on expert mode. It's pretty impressive. Uh, especially to be able to find fruit in the dark like good job guys, their fur is really nice and fluffy, so they can actually stand, especially the, like the Azara's owl monkeys, those ones are in Argentina where it can be a bit colder as well. Uh, so they can handle some decently cold weather that gets them an extra bump as well. Uh, that's how they got to that, you know, that seven, five. Yeah. Let's see. In terms of their ability to move on branches, I gotta, I gotta give it up for 'em. They're they're pretty nimble on those branches.

Ellen: Spectacular dexterity.

Alexi: The, yeah, incredibly dextrous. Though, when it comes to their, their manual dexterity, their ability to use their fingers, not so good.

Ellen: Really?

Alexi: Yeah. They--

Ellen: that's kind of the monkey's whole thing, right?

Alexi: I know. Yeah.

Ellen: It's like what monkeys do.

Alexi: Yep. Yep. Their fingers are long, but they're not super nimble fingers. I'm giving them a five on, on that manual dexterity. Sorry, guys. Hate to do that to you.

Ellen: Aw, man.

Alexi: I know right?

Ellen: Can't get 'em all.

Alexi: Yeah. You know, uh, their teeth aren't very sharp. Not, not a good bite. They can't really physically defend themselves very well. So in terms of defense adaptations, they, they really do need to stick to, uh, camouflage, which works really, really well.

Ellen: I was gonna ask, like, what kind of predators do they need to look out for?

Alexi: Yeah. Yeah. So if they end up having to go to the ground, we're talking about anything. I mean, even if they're in the trees and ocelot is gonna be a danger to 'em, uh, if they go down lower in the canopy or on the ground animals, like jaguarundis are gonna be dangerous, which is a brown, medium size cat found in south America.

Alexi: And then, you know, I'm sure a Jaguar would snag them, if given the opportunity. Plenty of birds would take the opportunity to hunt them. If they were spotted during the daylight hours, a harpy eagle is gonna make a snack out of them. Owls of various kinds are gonna hunt owl monkeys, brutal namesake, but you know, it is what it is. Larger arboreal boas and snakes. Would eat them, especially when they're younger. A young owl monkey, like an infant would be a snack for like, you know, rainbow boa of a larger size or a boa constrictor of any kind in the, in the trees. Though an adult owl monkey is a little bit, it's a little bit big, uh, for some of these boas.

Ellen: I'm sure that fluff is helping them out a little bit there making them look a little bigger.

Alexi: Yeah. If they were to fall in a, in a lagoon or any water, uh, a crocodilian of a kind would definitely snack on them being a small monkey, basically anything that eats meat is gonna, is gonna look for you.

Ellen: That's true. It's rough out there.

Alexi: Yeah, it really is. It's scary out there for a monkey.

Ellen: Does them being nocturnal seem to help at all with that? Like, I guess what I'm wondering is what is the advantage to being nocturnal, right? Like if they're the only ones of the monkeys that have figured out living at night, like, why wouldn't everybody do that? like, what's the benefit there?

Alexi: I mean, considering that they're an animal that leaps from a branch to a branch, doing it in the dark is it's pretty risky behavior.

Ellen: Right? Like that seems like you've cranked up the difficulty on yourself.

Alexi: Yeah. Yeah. I can imagine things that make a monkey's life, a monkey's life, like looking for bright colored fruits, uh, you know, all those become quite a bit more challenging in the dark. So I can imagine that the cost of benefit ratio for other monkey species, it just might not be there, or it might be just luck. Or, you know, it's possible. I mean, they adapted a very long time ago. I don't remember the years, but it was quite a long time ago. And so there may have been other nocturnal monkeys of a kind that developed that, and then it just didn't work for 'em. Uh, so they may have pivoted back if you will, or they may have just died off. So it, it is possible that it was something that a lot more monkeys did in the past. And it just, at one point stopped paying off, uh, or things might have changed.

Ellen: Mm, sure. It seems like such a strange holdout that they're like, mm, yes. Me, a creature who has adapted to thrive on vision, I think I'm actually gonna do this in a time when visibility is extremely low.

Alexi: Yeah. Well, and during the day they're really hard to spot in general. Even the ones that I work with it, it'll take me a few minutes to identify 'em in a space that's not all that big compared to a forest. They're incredibly cryptic. So they do have the benefit of that, where a lot of these sight based predators that operate during the daytime might not be able to find them very well. Uh, to be honest, there isn't a lot of data on them because they, uh, they move so high up, they move typically in the dark and because they are so well camouflaged, the primary research that I see on owl monkeys currently is being conducted in Argentina in a, I believe it's like it's a research park, essentially. Uh, so it's, uh, it's a defined area where they can study the WL monkey behavior. And a lot of research is coming out of them. I wish I could remember the institute's name at the moment.

Ellen: Hi, it's me editing this episode. The research park is called the Marikina Reserve. It is a field site that is operated by The Owl Monkey Project, which is a multidisciplinary research site in Argentina, studying owl monkey behavior. You can learn more about their work and this research site at owlmonkeyproject.com.

Alexi: Aside from that, it is most of what we know about owl monkeys comes from their behavior in captivity, which is altered from their behavior in the wild. So as time goes on and hopefully as research may increase, hopefully we'll learn more.

Ellen: I pulled up a Google image page of pictures, of owl monkeys, um, for me to peruse so that I have a good visual of what you're talking about when we're talking about these cool monkeys, cuz like I said, I'm not very familiar with them, but I do definitely see what you mean by how like their fur it's fluffy, but it's also that same sort of grayish brown color of like the bark of the trees. So it makes a lot of sense that they would be naturally very difficult, not just to find if you're a predator but if you're a scientist they're difficult to observe. So yeah. It's gonna be really hard to see what they're up to if they're so well camouflaged.

Alexi: And it's hard to catch 'em too, if you wanted to like, you know, put markers on 'em because how are you gonna catch it in the trees or, you know, even if you like wanted to dart it, say, it's like, how are you gonna catch it? Like when it falls. So it, there are so many logistical challenges to, uh, to studying them and a really cool thing that maybe you can see this on your, uh, image search, but when owl monkeys are sleeping, they actually curl fully up into a ball.

Ellen: Oh my goodness.

Alexi: Uh, so the only thing you see is the back of their neck essentially rolled forward. Uh, so they actually have their head almost between their legs tucked up as they sit on a branch. Um, they, they just look like a literal bump on a log.

Ellen: Yeah. Cuz when they curl up, they're really hiding like their markings and that sort of like brighter underbelly that they have. So all you're getting is just like that grayish, brownish, it looks like it's just part of the tree.

Alexi: It really does.

Ellen: Is this something that frustrates you working with them?

Alexi: Uh, no, fortunately they like most other primates human and non-human, uh, have habits. So if, uh, I know where they tend to hang out so I can look in those spaces and I can expect to see a monkey. I just have to look long enough and then my eyes will register 'em.

Ellen: Oh, sure.

Alexi: So for those who don't know, I work in, uh, actually a nocturnal setting, so everything is reversed for an owl monkey, so I can see them being active. I can make notes on their behavior. So with, uh, when I first come in in the morning, though, it's on a daylight setting. Uh, so when I look to see if everyone's good and well, that's when it's hardest to find. I work around sloths as well and they are, uh, the one that I work with in particular, she is very hard to find when she's just sitting right in front of my eyes.

Ellen: Well, she's also not helping you by moving around.

Alexi: No, no. Um, something that's really cool, on the topic of their coloration though, is that, uh, recently I think in the last four months, maybe five months, it was actually noted. An owl monkey who had albinism.

Ellen: Wow!

Alexi: Yeah. So, uh, a researcher, I don't think they were focused particularly on owl monkeys, but they were in South America researching something. And a lot of people in the area were, were telling them about a white monkey that they had seen. And a lot of times researchers, uh, especially Western researchers who aren't from an area when they hear indigenous people talking about a thing in their area, a lot of times they get written off. And those researchers, when they do that, they are, they're essentially missing an opportunity at learning something new.

Ellen: Right.

Alexi: And so this researcher in particular, he, like a lot of successful researchers in indigenous areas who help indigenous people, he listened to them. That's really important. He listened to them, uh, and they showed him where this was and he got pictures of it. That being said, you know, it's really important that getting those pictures and then, you know, getting that data. It's really important to remember that we have to protect those animals, not just in words, but when we get pictures of animals in South America that may have unique fur colorations, or maybe an endangered reptile, it's really important to remove the geotagging data. Because people can use that to find that animal, uh, and then capture it.

Ellen: Oh, like the metadata from the file.

Alexi: Exactly. It's really, really important, especially for herp researchers. Uh, I can't stress this enough. If you see a unique or an endangered reptile or amphibian, and you get pictures and collect data on it, you have to remove the location data. Uh, and that will protect that animal so that it doesn't get, you know, captured, you know, a year or two down the line.

Ellen: Right. I think it might be a lot of, people's like initial reaction to think like, oh my gosh, I found this amazing picture of this beautiful animal. I have to share it. And like, let everybody know like where I found it. So like, like you have this inclination to want to share that information, but like you said, you know, it's important to think about, is sharing this information gonna put this animal at risk?

Alexi: Exactly.

Ellen: I think a couple months ago we talked about, you know, the ethics of primate photography.

Alexi: Oh yeah. That's, that's a big one.

Ellen: Yes, we, we talked about the slow loris. So we were talking about like being mindful of the kind of content that you're sharing online when it comes to like taking pictures of primates and like what's the context of the picture, is that made clear in the picture? You know, like the ethics of wildlife photography can get way stickier than I think people realize at first.

Alexi: Yeah. Yeah. You know, and you know, to be fair, it's hard to predict what another person is going to think of something. But that being said at this point, we now have, you know, uh, years of understanding of, okay, what is, what is typically a misconception that is being taken from this type of picture? But it's really important for us to at least begin asking ourselves those questions, uh, and really looking at it with a critical eye because you know, the attention that your picture may get may be bad attention as a whole.

Ellen: Right because, you know, you're essentially blasting the GPS coordinates of this animal that might be of a high dollar

Alexi: value. Yeah. And a question that I have, you know, we know that albinism has an effect, uh, on hearing and vision, at least in a lot of species of mammals. Uh, and so my question is, I wonder how, uh, the albinism affects the, the owl monkey's vision and affects its hearing. The one thing that they noticed that the owl monkey in particular was squinting a little bit more than the other ones around it. Now that may just be circumstantial. It may just mean that, uh, you know, that one might have just been waking up and so its eyes might not have adjusted to the light, or it may have been, uh, having, you know, more light sensitivity than the other ones. Uh, so those are, it opens a lot of questions that hopefully will have answers to.

Ellen: What I've always heard, cuz I've always heard. I think , I don't know if this is true, that albinism increases light sensitivity that an animal or a person who has albinism would be more sensitive to light and therefore be like more receptive to light in their eyes. and then that would make me think that if a, if a nocturnal primate who is relying heavily on vision had increased light sensitivity, like that might actually help them.

Alexi: Right. Right. Is it, yeah. Is this something that is accidentally a positive in unexpected ways? Uh, or does it affect how that light sensitivity occurs? You know, cuz it could be really complex in, in how, how is its vision altered? You know, does it have the same like number of like rods versus cones what's changing in the structure is their vision more sensitive to light, but slightly warped in a way, because a structure is slightly changed. So for people who don't know albinism is, you know, the lack of pigment, uh, melanin typically in your body. So it's what leads to white animals that have red eyes, you know, so think about the, the rabbits that you may see at a pet store that have been bred to be white, uh, with those red eyes, uh, that is caused by albinism. Leucism is very similar, but Leucism is where they have only some pigments.

Alexi: So if you see an animal that is white with blue eyes, sometimes that will be, uh, a leucistic animal. So the genes that cause us to have that melanin and the pigmentation in our skin, eyes, hair, uh, and sometimes even nails, that is a very, very complex gene. It affects a lot of things in our body. It's a gene that connects to a lot of traits. So when that gene has that, like, you know, very recessive output where you don't have any pigmentation in your skin or eyes, uh, hair, et cetera, that also is gonna affect how the other structures in your body that rely on that gene are built. Uh, so I work with a, uh, a white alpaca and she has no hearing because that is a trait that is associated with her leucism. It's really complicated stuff. Uh, so yeah, the question is like, how does albinism, how does being albino affect, uh, an owl monkey. Or how does it affect this one? Because we, you know, one isn't a sample, but it's a little bit.

Ellen: N of one.

Alexi: Yep, yep. Yep.

Ellen: Well, I mean, even if albinism does help its eyesight, it also loses camouflage.

Alexi: Mm-hmm, yep.

Ellen: So then like, is it worth it at that point? Like, are you gaining enough of an advantage to make it worth losing your camouflage? Which it's based on what you said, it kind of sounds like that's its only line of defense.

Alexi: Mm-hmm and running, you know, running in escaping and they're pretty good at that.

Ellen: I would hope that this albino one is really good at running.

Alexi: Yeah, me too. You know, I hope it lives a long life. It seemed like it was part of a family group. And so it might have still been a juvenile, but that being said it was adult-ish sized. So it survived through its infancy and its uh, childhood.

Ellen: That's a promising start!

Alexi: Yeah. It's on its way to being an adult and you know, maybe it'll make a, you know, a pair bond itself.

Ellen: I would be delighted to hear more news of the albino owl monkey. I'll be keeping an eye out for, for updates on their story.

Alexi: Yeah.

Ellen: You mentioned earlier that, you know, the, the owl monkeys that you work with, you know, you work with them in a captive setting that is in with like a low light setting, but that their behavior in captivity is different from what you would see the behavior of a wild animal exhibiting.

Ellen: So you mentioned that what is known about their behavior is based on a captive setting, but just based on like what you know, and what you've heard and what you've experienced with these owl monkeys, let's talk ingenuity, which is our next category that we rate animals on. And for us, ingenuity is just like how well their behavior, like things that they're actually actively doing with their body, like helps them solve problems that they face or, you know, thrive in their environment. What would you give your owl monkey friends out of 10 for ingenuity?

Alexi: Okay. So for ingenuity I gotta, I gotta rate 'em low. Okay. I gotta rate em low , although keep in mind that owl monkeys, like most animals, their, their competency and their skills are on an individual level. You know, some of, some of us humans, we are incredibly intelligent.

Alexi: Uh, at large, but you know, some of us have very different intelligences. Uh, so, uh, this is me hedging my answer already before I get roasted online for flaming these owl monkeys, uh, they, they're not the smartest primate that you'll ever meet. I'm gonna, man. I'm sorry guys. I gotta hit 'em with like a four or a five.

Ellen: Okay.

Alexi: On the ingenuity. Like they--

Ellen: I'm sorry, babies.

Alexi: Sometimes they feel like deer. As they move through the trees. Um, no, no, they're, they're intelligent. Um, but if we're comparing it to a lot of these like very smart primates, uh, you know, I have to give 'em a, a lower score. They quickly, when they can't figure out a problem, they quickly move to, I'm gonna break it immediately. They're like, I'm gonna shake it. I'm gonna break it. And that's, that is the problem solving ability that I have seen so far though. Some individuals are, uh, definitely, you know, of the three that I currently work with, there is a marked difference in each of their competencies. You know, one of 'em, she is, uh, "I'm gonna shake it I'm gonna break it" kind of animal.

Ellen: Same. Love it. Good for her.

Alexi: Yeah. Right. The other one he's very gentle. Uh, but he also gives up.

Ellen: Oh, no!

Alexi: So yeah, he, he looks, he moves, he kind of shakes it, he tilts it, you know, he does the thing. And then he says, okay, well that's not anything real.

Ellen: This wasn't meant to be.

Alexi: Yeah. Yeah. He's not stressed about what he can't control in his world. He looks at his world around him and he is like, I don't have power here. So I'm gonna move on to things that I do know. And I respect that. That's a good way to maintain your peace.

Ellen: How much can we learn from this baby?

Alexi: Exactly. And then, uh, and then the third one who is their infant, it has learned that if the adults figure out the problem, he can eat out of their mouths.

Ellen: Mm!

Alexi: So I respect that. I have heavy respect for that, but yeah. Yeah. So, and you know, when we compare him to other primates, uh, we gotta score 'em pretty, pretty low on their ingenuity.

Ellen: I've heard about owls and perhaps this is also the case with owl monkeys.

Alexi: Yeah. It might be.

Ellen: I've heard with owls that they also have these big, enormous eyes for seeing well in low light and that they had to make room for these big giant eyes by, uh, reallocating some of the cranial real estate that would've otherwise been dedicated to brain. And so they just kind of traded brain for eyes. And so you get these giant eyes with quite little behind them.

Alexi: Yeah. Yeah. So their brain mass to body mass ratio, isn't, isn't the highest, it's not very big. Uh, they do have to make a lot of, a lot of room in their head or in their skull for their eyes and the optic anatomy, uh, that comes along with it. You know, but their, you know, their focus is on moving, finding, and also they, they do form these very, not very large, but very complex social bonds between two individuals. A lot of their, you know, their learning does go towards that and then understanding their environment. So they, they do learn what they need to know. So if I could say that, so they, they get the job done.

Ellen: Sure.

Alexi: You know, they, you know, being the smartest animal out in the forest, isn't always a winner. You know, if I, if you plop me down in, in the rainforest, I'm not gonna do very great. I could count the change in pocket real fast, but that's not gonna help me survive. Uh, in the words of another, but, uh.

Ellen: Priorities.

Alexi: Yeah. Yeah. So, you know, I'm gonna bump them up to a five because they get, they get the job done, but they're just, they're not killing it in terms of problem solving.

Ellen: That's fair. I mean, who, who among us, who is?

Alexi: You know, especially now these days, who. Who is truly getting a ten. And if you are, tell me your secret.

Ellen: Who's firing on all cylinders these days. None of us. So I told you that I looked up pictures. And so I'm looking at like the Google images, results page. And I'm seeing a lot of these headlines on here that are referring to owl monkeys as very good dads. This one says best dads on the planet. Um, this one says that they are the best father in the animal kingdom. What's going on with owl monkey dads?

Alexi: Yeah. Owl monkey dads are great. Uh, if you ever are blessed to see an owl monkey dad doing his dad thing, it is delightful. It is something we all can learn from. Uh, so. Owl monkey dads. Uh, so basically mom, you know, shoots out a baby and then dad oftentimes will go get it off the ground. Uh, or one of 'em will go pick it up off the ground. Uh, if it makes it all the way down.

Ellen: Oh, you meant like she SHOOTS the baby. She is like spiking it down on the ground.

Alexi: She will have have the baby and the baby is very large. Uh, they only have one offspring, uh, and it's a very large, very developed baby, but dad oftentimes will get them off of the ground, uh, pick them up because they are arboreal. Uh, so the baby doesn't immediately grab on sometimes or if it's held by the umbilical cord, dad can catch it.

Ellen: That's very similar to how humans do it. Like like how a lot of times the other partner of the person giving birth will be like, they're waiting to like catch the baby, right?

Alexi: Yeah. Especially if you go up onto the balcony to have it. Yeah. So these, these owl monkey dads will do a lot of the rearing. Uh, they'll do a lot of the raising, uh, and mom's main job at, for the majority of the infancy and childhood if you wanna call it that, her job is to simply take care of herself and produce milk. That is it. Like she she's there to provide the food. And dad, dad literally will carry that baby on his back and will teach that baby everything he knows. Uh, that's packed into that little tiny monkey brain. Uh and, and so you see a lot of play behavior between the dad and the owl monkey infant. You'll see, usually the way you can spot the owl monkey infant after like a couple of days is usually, uh, on dad's back, riding him like a, like a horse.

Ellen: Oh, my goodness. That's the most precious thing I've ever heard.

Alexi: It's it's adorable. It's adorable. You can only really tell the baby from the dad by looking for a baby shaped imprint, it looks like like Daffy duck getting blown through a wall. You know, it's just the shape of the baby on the dad. It's incredible.

Ellen: I mean like what a great arrangement also, because like I have given birth to two kids and you need as much help as you can get in that honestly, in that time right after having a baby. So, I mean good for them for having figured that out.

Alexi: Honestly, gentlemen, carry the baby. Carry that baby. Please walk around with that baby. Teach that baby. Love your baby.

Ellen: Put that baby on your back. Get you one of those baby backpacks.

Alexi: Oh my gosh.

Ellen: Even just like the, the cloth that you could just like wrap around. Yeah. And carry the baby on your back. Like it's comfortable. You get that weight off of your hips. It's fun.

Alexi: Yeah, it's wild. The dad was carrying the one that I worked with is, or he was carrying the baby around for as long as a year. And then eventually he started like fighting the baby. He's like, you will get off of me now. You are almost my size. Yeah. Cuz the baby will do that until it's almost half the size of, of the adult. Uh, which is incredible. When you really think about that, they're still having to run. They're still having to jump. Uh, but it really, when it comes to this pair bond that they have, they're, you know, more equitably sharing the resource load because when you get down to it, a lot of things, uh, in the wild boil down to, you know, resources, you know, of one kind or another. And it's often even further boiled down to energy, expenditure, energy going in and energy coming out. If more energy is coming out than is going in, that animal is not gonna survive for very long. So dad shares the load of energy that has to go into this baby that the baby is using to grow, uh, and hopefully survive later on. So mom can focus her energy on surviving herself, first of all, and then also on getting enough food that she needs in order to produce milk, which is incredibly energy expensive. Uh, I, you know, a lot of people may not realize that, but it, it takes a lot for our bodies to produce that. Especially if you are trying to run it and hide from predators and you have to walk around and forage for your food, you have to find these small supermarkets through spread throughout the whole neighborhood just to eat a meal. Uh, so, you know, that makes it so that they have a better chance of surviving, both the adults and the offspring.

Ellen: I guess it makes sense that they have such a small litter size of like only having the one baby at a time. If they're putting so much effort into, like both parents putting so much effort into this one little baby.

Alexi: Yeah, that's right. And they will raise that baby. And that baby will stay with them for roughly around three years. So they'll have one that one will grow up and become semi independent, but it'll stay with the family where it will start to learn also how to rear and how to raise offspring by, you know, observing its parents' behavior as the next one is born. Uh, so with some of 'em, there may be like this little like conveyor belt, you know, where it's like, you know, the one that was just raised, you know, learns how to, and then helps raise the next one coming up too.

Ellen: Oh, multi-generational families.

Alexi: Yeah. Yeah. And then of course they have to move on and go find a partner of their own or just live about.

Ellen: It's the circle of life.

Alexi: Yeah. It's actually a pretty cool little structure. I love it.

Ellen: Everything you've told me about these creatures so far has been relentlessly delightful.

Alexi: Mm-hmm yeah. Yeah. I'm gonna drop one more on you because their fur is actually very soft to the touch. It's like, it's not like a chinchilla, but it's kind of close. It's close enough. It's it's dense. It's soft. The strands are very thin, but to be honest, I rock climb. So my hands aren't the most sensitive. So maybe someone who has like, actually sensitive fingers might be, might be like, this is not anything.

Ellen: Well, I mean, like compared to what a lot of other like wild mammals that you see, they typically, I feel like usually like a wild mammal you could expect to have pretty like coarse, not the most like sensory appealing material, but I love a good soft critter. Well, since we're talking about, uh, how delightfully soft their fur is and how adorable they are and talking about their babies, let's talk aesthetics for the owl monkey. This is a very self-explanatory category, but what do you give the owl monkey out of 10 for aesthetics?

Alexi: So I'm gonna give them two different scores. Okay. I'm gonna score them on minimalism.

Ellen: Okay.

Alexi: And then I'm gonna score them on kind of like a, a more maximal scale.

Ellen: Sure.

Alexi: So in terms of like minimalism, I think they do a lot with very little, they have only what, three or four, four different colors on their body. It's usually like a gray, a black they'll have like, sort of like a rusty brown, almost like an amber color. And that's usually seen on the inside of their arms, whereas like the grays and blacks are on their back. And then on their face, they have, uh, these like white markings above their big brown eyes and then between their eyes and then on the outside. So on the temple, they have three black lines that go up and back across their head. So I think they're doing a lot with very little. So in terms of minimalism, I think I'm gonna give 'em a solid seven or eight.

Ellen: That's good.

Alexi: Maybe even a nine, depending on the individual. Cuz some individuals are gorgeous looking. They're just so fluffy. So nice looking. And then in terms of like, you know, maximal, like kind of peacocking, you know, comparing to all of those really, really wild ones, I'm gonna give them like a five.

Ellen: Maybe a low pizzazz sort of creature.

Alexi: Exactly, exactly. Their colors camouflage them. They do the job, but they're not, you don't look at 'em and say like, oh my gosh, like, what is that? Who's that girl, you know, you don't, you don't think that would see them.

Ellen: Who is she?

Alexi: Right. You're more like, oh my God, it's looking at me.

Ellen: They're not the ones making the grand entrance to the ball.

Alexi: Exactly. No, it's one of those things where the more you look at them, the more you appreciate them. Yeah. So they have that slow burning beauty. That's what that is.

Ellen: It's subtle.

Alexi: Exactly. Exactly.

Ellen: They are incredibly cute. And like, like you mentioned, the, the white markings above and below the eyes, it reminds me of this thing that I've seen mostly I've seen cause players do this when they use white makeup above and below their eyes to make their eyes look like a cartoon.

Alexi: Mm-hmm yeah.

Ellen: That's what it reminds me of because it makes their eyes look like really big and tall.

Alexi: That's wild. Cuz that you finally like nailed it. That like I was like, what does that remind me of? And it reminds me of cosplay makeup a little bit. Yeah.

Ellen: Like when you're trying to make your eyes look like a cartoon character like I've seen people do this for like Jessica Rabbit cosplay and stuff where they'll like, make your eyes really big.

Alexi: Oh, that's bonkers. Yeah. That, that is it. That's the vibe. That's the vibe, we did it.

Ellen: It works well, it looks really cute. It also makes them look like they have like eyebrows which is like, they kind of don't, but they kind of do, like, it makes 'em look like they have eyebrows, which makes them to a human look, more expressive.

Alexi: Yeah. And I wonder if you know, I'm not exactly sure what the, uh, what the utility of those markings are, you know, I wonder if it's the contrast for them to identify each other. Oh, uh, in the dark with especially identifying individuals, uh, because they're all slightly different looking in their face, especially the more familiar with their faces you get, uh, the more you can recognize that they have individual faces. Uh, if you think about it, like if you have ever been friends with a pair of twins, you know, at first you're like, I can't tell them apart, but then over the years, you're like, I could never mix them up. Yeah. As you become more familiar with what their individual face structures look like, it becomes pretty difficult to mix up different owl monkeys. So I wonder if there, if that is part of the utility of having those not necessarily complex facial markings, but very contrasted facial markings,

Ellen: I guess that would make sense for a social, like a creature that really puts a lot into their like social interactions. It would be important for them to be able to tell each other apart.

Alexi: Right. Right.

Ellen: Or at least like having a high contrast so that it's easy for them to identify where each other's faces are. Like in the dark, I guess. Yeah. That would make sense. It also reminds me of the markings on the face of the, uh, the slow loris um, yeah, to bring them up again.

Alexi: Mm-hmm, slow lorises are amazing primates. They're wild.

Ellen: Spectacular creatures. And they have those, you know, those bright white markings on their face. I read somewhere that in the slow loris, it was to mimic a spectacled cobra.

Alexi: Yeah. Yep. I was wondering if you guys had already talked about that. Uh, and the fact, I think if I'm remembering the right primate, I think they also hiss as a part of their defensive posture, they also weave back and forth.

Ellen: Yes! They put their hands up and hiss to look like the hood of a cobra.

Alexi: Yeah. And if you see a picture of it, it does look like one, especially if you look at it in kind of like a low contrast or low light, imagine what that looks like in the dark. It's like, oh, that actually does kind of look like a Cobra. Uh, and then on top of that, they're a venomous primate. Like as far as I know, they're the only ones that are venomous.

Ellen: I think so. Yeah. I'm pretty sure. But they fully copied the Cobra, like copy and paste.

Alexi: Right. I, you know, I don't support plagiarism, but I respect it. I get it.

Ellen: Well, listen, that's like very much a human value, you know? Right. Like what if, uh, plagiarism is totally fine.

Alexi: Listen, colleges. Nature doesn't uh, have a no, you know, a full hand -- I can't get that joke out. I couldn't find my way there.

Ellen: I, I don't want any, uh, colleges reaching out to me and being like, um, please don't advocate for plagiarism on your podcast. Please don't do that. The last thing I wanted to say about like the aesthetics for the owl monkey, because I've literally been staring and scrolling through this, these Google photos, like this whole time we've been talking, is that I do wanna give props to the eyes.

Alexi: Yes.

Ellen: Because I understand that the eyes are like an adaptation to help them survive. But I gotta say it's also super cute.

Alexi: Yeah, they're gorgeous. They have very pretty eyes, especially when you see them open in low light, you know, when their pupils are like maxed out and max size. Oh, it's, it's adorable. They look like the picture of the, of Puss In Boots from, uh, from Shrek.

Ellen: It does! Yes! I was trying to place what --

Alexi: It's so cute. I'm like, ah, dang. You know? Okay. So yeah, I'll bump them up a point on both accounts.

Ellen: That feels appropriate.

Alexi: Yeah.

Ellen: I dropped a link in the little squad cast chat to the exact photo I was looking at. When you said that they look like Puss In Boots with the begging eyes.

Alexi: Yep. Yes. Uh, they're they also have pretty spectacular little cheekbones. This one is, is a very good picture. Uh, this, this picture that we're looking at, it is an owl monkey. I assume it's a dad cuz the baby is on its back looking over his shoulder.

Alexi: But this owl monkey has a very thick neck, but it has very, very prominent cheekbones. And it has like a small chin and like big pouches on its upper lip. A very adorable owl monkey. Just, that one's a winner.

Ellen: It looks halfway between a monkey and a cat.

Alexi: Yeah. So a really cool thing. If we wanna talk about eyes real quick, in terms of cats, you know, a lot of people identify cats with the cat eye, uh, that slit pupil, both of them typically nocturnal animals, uh, you know, cats are more crepuscular, but you know, they move around in low light conditions, especially a lot of smaller cats. Uh, the reason why an owl monkey is gonna have a large circular pupil rather than a slit pupil is because they typically aren't on a surface. So what I mean by that is like, they're on a branch, but they're not on these, they're not on the ground. They're not low to the ground, or they're not on the trunk of a tree, a very long, very large surface area. So a slit pupil helps an animal that is low to the ground, moving in low light conditions. Uh, it helps them see really, really well. I don't exactly know how it works. I'm still like wrapping my brain around it, but that's why you'll see some like nocturnal snakes with slit pupils.

Alexi: That's why, uh, domestic cats and small cats typically have slit pupils. And that's why larger animals that are nocturnal don't have slit pupils like tigers and lions. They will be incredibly active at night, but they don't benefit from having a slit pupil because of how tall they are. Oh, and how high off the ground they are.

Ellen: But they're mimicking being tall just by being up high in the trees.

Alexi: Yeah, exactly, exactly. Being high off of the ground. Uh, they benefit from having a circular pupil. It's, uh, it's the way that they can maximize their vision and that slit pupil just doesn't really do a lot for 'em probably.

Ellen: Oh, that makes a lot of sense though. Yeah. When you get into like the science of vision, it becomes magic at a certain point.

Alexi: It really does. It. It really does. I, you know, I firmly stand behind like science is really just the method for understanding magic in the universe.

Ellen: The rules of magic.

Alexi: Yeah. It, it really is. It really is just the rules of magic and how it works. Like that's part of physics and why the physics field even exists. It's like here is how we learn magic and how it works.

Ellen: This is how magic works.

Alexi: Uhhuh . Yeah. Yeah.

Ellen: These are just the rules that our magic adheres to.

Alexi: Mm-hmm . Exactly, exactly.

Ellen: And no better manifestation of the magic of the universe than the spritely little fairy that is the owl monkey. What a sweetie. I'm obsessed. Okay. I. I'm in love. I'm thoroughly thrilled by everything you've told me about owl monkeys here today, before we get wrapped up I really wanna talk about your podcast.

Alexi: Oh yeah.

Ellen: I have listened to every episode. And it is just so delightful and funny and insightful.

Ellen: And also, I don't know if you do the sound designing, but the sound designing is fantastic.

Alexi: Thank you. Yeah, I do. I do the sound design on there. Yeah.

Ellen: Oh A plus. I love it. I'm always thrilled. So let our friends listening know more about your podcast.

Alexi: Yeah. So my podcast that I work on with co-host Allison Jones is the We Out Here podcast. Uh, it's a storytelling podcast that centers around, you know, fun experiences or et cetera, uh, of black, brown, and indigenous folks in science and nature. So a person comes on with Allison and I, uh, they tell a story about being in nature or being in one of the sciences. And yeah, we just have a good time with it.

Alexi: You know, I love storytelling. I think it's one of the ways that we process our world and learn about our world. Uh, it's a way we share a lot of information, especially historically through oral traditions. Uh, and so this is a way that we can kind of maintain that. It's also in its goal and in earnest, you know, a lot of black and brown faces and indigenous faces, aren't the faces of science or the faces of nature in terms of like naturalists. You know, we think of, uh, Jeff Corwin, the Kratt brothers, uh, Steve Irwin, and all of them respect to them and all they've done, but, you know, we want to normalize our presence out there as well. So. You know, just sharing these stories is, you know, it's a little step forward for that. Plus it's a, you know, it's a fun format. Uh, plus we can have funny sound gags on there. Uh, and it, it really made me fall in love with audio editing as much as I, uh, get frustrated with the process.

Ellen: I can relate to that.

Alexi: Yeah. Yeah. So that's the we out here podcast it's on every major platform, uh, for podcasts, uh, in episodes, we try to keep 'em short, you know, about 30 to 40 minutes. So they're a nice little like commute podcast for you.

Ellen: I was gonna say it lines up like, almost perfectly with my commute, usually like, yeah, it's the sort of thing where I'm like pulling into the parking lot at work, right as the episode's ending.

Alexi: Yeah. And we, we drop new episodes once a month. So the primary episodes drop on the 15th of every month.

Alexi: And then on the first of the following month, we drop, uh, what we call the "kitty cut" and that's a cut that's edited for, you know, for younger more sensitive ears. Uh, so if you have an audience member or you yourself are a little more sensitive to, you know, the colorful language, uh, we, we cut a bit of that out and we make it a little more kid friendly.

Ellen: I love that. Yeah. I know that there are, you know, a lot of kids listening right now that would probably love to go take a listen and hear some stories about folks, you know, enjoying nature. I just listened to the episode you had with Sylvana about beekeeping. And that, that episode was just delightful.

Alexi: Yeah. That story, when she, when she emailed us with that story me and Allison lost our minds, the, it took, it took a bunch of turns. Um, and for anyone listening, if you are, you know, if you're black, brown, or indigenous and you want to share your story with us, uh, send us an email at: weoutherepod@gmail.com, you know, hit us with that story and we'll give you more details on how to, how to be on the program. But we are always looking for more folks to join us with stories in, you know, keep in mind, we're not looking specifically for traumatic stories or trauma of like harm or anything like that, but just, you know, your experience in life, in and around the trees.

Ellen: And also for folks that maybe want to follow along with you and your work, not just science communication, but just wanna connect with you. Where can folks find you?

Alexi: Yeah, you can find me on Twitter, uh, at @alhendiify, and that is at A L H E N D I I F Y. Wow. I almost couldn't spell that for a moment. No. So that's where you can find me on Twitter, um, for, be forewarned, it's not specifically a kid friendly Twitter account, so this is largely for adults.

Alexi: We discuss a lot of adult topics and that one is not specifically a scientific communication account, though I love to share information about animals. Uh, so if you're interested in discussing environmental justice, uh, social justice, or just in general topics of, uh, any interesting thing I run across. Yeah, come on and join me, check it out.

Ellen: I'll include a link to that in the episode description, by the way. So folks can scroll down and see all the links to where they can follow you and your work. Thank you so much for sharing your joy and your knowledge and your enthusiasm with us here today. It has been an absolute delight.

Ellen: Thank you so much, Alexi. We will talk to you later.

Alexi: Thanks for having me on. I'll see you later, Ellen. All right, bye.

143: Muskox w/ Kirsten Engeseth!

Ellen: Hello friends and welcome to episode 143 of Just the Zoo of Us. Just super quick before we get started with the episode, I want to say thank you. We wrapped up the Max Fun Drive last week in excess of our membership goals. Thanks to those of you who showed up for us in an incredible way. Not only are we going to be delivering on that really cool new content that we promised, like video game live streams, and next week's episode where Christian and I are going to be playing DnD, but we're also able to make some really ambitious upgrades to the podcast itself that will be coming soon. And I'm really excited for you to hear about them. Basically, we get to continue creating and growing all because of you. And for that, I just want to say thank you for believing in us and trusting us with your support. Now time for this week's animal review. This week, I am talking with a scientist who joins us all the way from Norway to talk about the fluffiest softest living tank you have ever seen: the muskox! We talk about how these real life Banthas keep warm in the harsh Arctic winters, band together to defend their herd with unwavering honor, and do their absolute best to overcome the challenges of new environments and an ever-changing world. Just the Zoo of Us presents the muskox with Kirsten Engeseth.

[intro music]

Ellen: Hey everybody, this is Ellen Weatherford. I'm here with Just the Zoo of Us, your favorite animal review podcast. And this week we have a new friend with a really cool animal that is quite unique, and I have to admit, I know so little about, so I'm really excited for the stuff we're going to learn today. This is Kirsten Engeseth. Say hi, Kirsten.

Kirsten: Hi everybody.

Ellen: It is so nice to talk to you, and we're going to talk about a very charming and delightful animal today. But before we talk about our animal, Let's talk about Kirsten a little bit. Kirsten, you're coming to us from Norway. We were joking around a little bit before I hit record. And on your screen, it looks to me like the middle of the afternoon. It's quite bright, but you have informed me it is 8:00 PM.

Kirsten: Yes. That's the joy of these high latitudes. You have that long daylight hours in the spring and summer.

Ellen: Yeah. So you're all the way up north in Norway, which is way up there, where you get some chilly winters and some animals that are adapted to those chilly conditions in some really interesting ways. But before we dig into that Kirsten, what brought you to the work that you're doing with these awesome animals in Norway?

Kirsten: I am pursuing my master's degree at NTNU in Trondheim, Norway. And I came here because, well, I guess for two reasons, part of it is because I love the Arctic. I've always been really fascinated by Arctic ecosystems and the nature and the wildlife, but also my heritage is Norwegian. And so that always drew me to come back in a way to Norway. I've done two bachelor's degrees. My first one was in foreign language. I was interested in going into political science and linguistics, but after I finished that degree, I found rather than going into grad school, like I had anticipated, I just kept feeling a strong sense of regret that I didn't pursue my original passion in science and a big part of that was because I think growing up, um, we often hear, oh, if you're not good at math, you can't be a scientist. If you're not good in chemistry, you can't be a scientist. So I was really put off of pursuing science.

Ellen: I think that's really relatable.

Kirsten: Yeah. I think a lot of people go through that. And so for me, I realized that I wasn't getting the fulfillment from my career path that I wanted. I grew up loving animals as all of us have, I'm sure. For me, I think I always knew in the back of my mind that that was the path that I wanted to take. So, um, as an older student, I decided to do another bachelor's program at the University of Minnesota. And I got my bachelor of science in fisheries, wildlife and conservation biology. So my specialization was actually in fisheries because I spent a long time on the California coast doing marine science education and outreach. I worked in an aquarium for a while. I was really heading down this path of marine science and fisheries and my bachelor's program. It was really great because we could specialize in a field like fisheries, but also we had field courses in things like mist netting and banding birds and setting up camera traps. I did a wildlife immobilization class where we got to learn how you sedate and handle wildlife like wolves, mountain lions, bears. So I got to do a bit of everything. And I knew at that point, um, as I was wrapping up my bachelor's program, that I really did want to continue in this career as a scientist that really brought me the most fulfillment.

Kirsten: So I knew I was going to go for a master's degree. For doing a master's program, I looked overseas exclusively. I wanted to go to Norway in particular because I'm really drawn to the environment here. I mean, Norway is so well-known for its natural beauty. You think of the Northern lights and you think of the mountains and the fjords. Oh, it just doesn't get any better than that. So.

Ellen: I'm thinking of the romance from Game of Thrones, which I don't think was in Norway--

Kirsten: I think they filmed it in Iceland maybe, but at a certain point up north, it all looks the same.

Ellen: The sweeping landscapes, like you get a nice snow-capped mountain in there and ugh! Chef's kiss.

Kirsten: Yeah, it's just unbeatable.

Ellen: As someone who lives in the wetlands of Florida, which is like the highest up you're going to get. It's about 10 feet above sea level, it's the closest where you could get to a mountain. So, I mean, I see pictures of Norway and it's mindblowing.

Kirsten: Well, my field site is out in the mountains and for me as someone that doesn't come from a mountainous area, it just, oh, it took my breath away. But so I was applying to master's programs here in Norway, because I wanted to work in these beautiful landscapes. And also as someone who was specializing in fisheries at the time, Norway has a huge history of fishing and they're developing all kinds of aquaculture and fisheries management. The marine ecosystem here is really fascinating, so originally that was what I was planning on pursuing. The program that I'm in is actually called natural resource management in the biology program. And this is a master's degree that's based on how people interact with the natural environment. So it's not just the biology of these systems. It's not just ecology, but it's also how humans interact with and manage these systems. And how can we improve that relationship? And how can we bridge the gap between science and the people who live and move through the world? That's really important to me. So, um, it's, it was just like, I can study that in Norway? Perfect.

Ellen: And it sounds like a good merging of, like you mentioned, like the first interest of like language and political science and like bridging that and passion for natural science. Like they go hand in hand so perfectly.

Kirsten: Absolutely. Um, so much of natural resource management is people management. And for me, there's nothing more gratifying than like we're doing on this podcast. Just sharing my love of the natural world and the animals and plants that live there with people that either live in co-habit with these organisms, or maybe are half a world away and have never heard of them, or have never seen them.

Ellen: Like me!

Kirsten: And me for many of the other episodes that I've listened to, you know, there's so many that I've never seen. And, and for me too, like when it came to my study animal, like I said, I was mostly interested in fisheries and marine science and marine invertebrates. And for me to be studying large mammals, is a complete left turn. I always thought all the large mammals, everyone wants to do large mammals. I want to do something else, but, um, the more you learn about any animal you can become so invested and the muskox in particular is, it's a very emblematic species in Norway. Which is sort of interesting given their history, which I can tell you a little bit, a little bit about.

Ellen: I guess if you had like asked me what would be an emblematic animal of Norway. I don't even know if I could have given you an answer. I would have thought maybe a moose?

Kirsten: Yeah. Moose is the other really big one. So quite literally, one of the big ones. Yeah. So moose are, they're really common and Norway they're here by my apartment building, you know, they're, they're all over the place. So they're definitely an animal that people, when they think of Norway, they think of moose and also reindeer, which is one of my main study animals and the muskox, which is interesting because the muskox in Norway, it went extinct sometime before the last ice age.

Ellen: What?

Kirsten: So typically when you think of a muskox, their native range is Arctic Canada, Greenland, primarily they were in Alaska. They went extinct there too, I believe. Or were extirpated and then were reintroduced. So there's actually been a lot of reintroduction programs to bring the muskox to areas where they existed before the last ice age.

Ellen: Wow. Like before, before.

Kirsten: A long time ago.

Ellen: So like a lot of times when you hear about animals, like going extinct in certain areas, a lot of times that's kind of like at the hands of humans, right? This sounds like this is not that situation. Like they went exchanged for other reasons. Is that what happened?

Kirsten: The history of the muskox, as I remember it is that they wound up in these patches due to glacial retreat. So they were able to survive when other megafauna were not able to. So like, for example, the wooly mammoth went extinct. The muskox was still around, but human hunters that were moving and following this retreat also would wipe them out in certain areas.

Ellen: What do you mean by glacial retreat?

Kirsten: So just as the glaciers were shrinking or moving further up, so glaciers used to cover more land than they do now. And so as they retreated. They would leave these areas that have been thawed, essentially, so animals could survive in those areas. That's my, that's my very basic understanding. I'm not a geographer or geologist, but what I do know is that fossil records were found of the muskox here in Norway. They were, the fossils were discovered in 1913, I believe by people who are building a railroad.

Ellen: Oh wow.

Kirsten: And so they found fossil evidence of the muskox and that was how it was discovered that they had been in this area.

Ellen: Okay. So even as recently as within the last century, there were still no muskox.

Kirsten: Yes, correct.

Ellen: Wow. So this is a recent thing, huh?

Kirsten: It's really recent. And there had been multiple attempts at that point to bring the muskox back. And part of this was because Norway was wanting to have this emblematic animal. They wanted a big charismatic megafauna. Maybe the moose wasn't big enough. I'm not sure.

Ellen: Also I feel like Canada has dibs on the moose, right?

Kirsten: Yeah. I feel like Canada has, they're probably most associated with the moose.

Ellen: Right? You think of moose? You probably think Canada.

Kirsten: North American moose are bigger than the European ones. So...

Ellen: So I'm getting like slightly stunted on a little bit.

Kirsten: Exactly.

Ellen: Like, okay, well, if we can't have the biggest moose, then we'll do something else.

Kirsten: Polar bears don't come down this far south or up on Svalbard much further north. So you can't even have the polar bear down here on the mainland.

Kirsten: They need a W.

Kirsten: Yup, they needed something else, so they decided that they would try and bring the muskox back. This had varying degrees of success. So this is the early 1900s. So try and imagine, well, first of all, what does a muskox look like?

Ellen: Yeah, we should probably talk about " what's a muskox," right?

Kirsten: Right. Like, cause you need to picture them to understand how this would go. So a muskox is, I guess the closest thing for someone who's never seen a muskox I would say maybe picture a bison that is smaller and hairier and has bigger horns, or if you like Star Wars, picture a Bantha and that's it.

Ellen: Let me Google a Bantha real quick. Yeah. Now the Bantha has these big, like curly Q sorta horns. Is that what the muskox is like?

Kirsten: Yeah. So the muskox, if you picture a bison, they have these horns that sort of curl out and upward while muskox they curl out and down, back toward their face. So if you think of like a bob haircut, they sort of had this little like, the curl around the face, a nice little face frame moment, and then curl back out at the bottom.

Ellen: Bangs. They have bangs.

Kirsten: Exactly. They're like bangs.

Ellen: Well, I'm looking at a picture now and I want to say they also have a pretty fierce middle part.

Kirsten: Yes, they do.

Ellen: The middle part and the fringe bangs. This is a gen Z icon.

Kirsten: And that's actually one way that you can tell the females from the males, the females have a wider middle part than the males.

Kirsten: And this is because the males will actually use their horns for establishing social dominance. So head butting with other males. And so they have to have a tougher, stronger plate on their head. So the horns actually kind of form a headbands on the males.

Ellen: Oh, it's doubling as a helmet.

Kirsten: Yep. And on the females, they don't have that. So they've got that really strong middle part.

Ellen: Their horns are sisters, not twins.

Kirsten: Exactly. They're quite unique looking animals. There's not anything else that looks like them. They're quite large. They can be around four to five feet tall at the shoulder. It's hard to see how big they are in reality, because they have so much hair. Just an unbelievable amount of hair. They have a really thick insulating coat of under hair. And then they have these long course guard hairs that fall like curtains from their body.

Ellen: Have you ever seen one like soaking wet so that the hair all lays down so you can see like, like, imagine, actually like the size of a dog underneath?

Kirsten: I've often wondered about that. I've always thought "I wonder what they would look like if you were to, like give them a poodle cut or something." Like, I want to know what they actually look like under there. I know they have like a shoulder hump and apparently when you're looking at one, you're like, where's the neck. Because there's so much hair and they're so round that you can't really make out any musculature, but apparently even underneath all that hair, they don't really have a neck because they're just so stout. I would just love to see what they look like underneath all of that.

Ellen: Okay. So you mentioned that they, you know, they do look like a bison, they have the word ox in the name, the name, what are they relate --I mean, are they like a cow or are they like a deer? Like where are they in the family tree?

Kirsten: Yeah, they're kind of often their own part of the family tree. Everything about their name is a misnomer. A muskox is not an ox. Nor is it musky.

Ellen: O for two.

Kirsten: Yeah. So it's really a poor name, to be honest.

Ellen: 0% accuracy.

Kirsten: Exactly. I don't know who was in charge of that, but they really dropped the ball on that one.

Ellen: Hello friends. It's me editing this episode with a real quick clarification of this point.

Ellen: Kirsten let me know after we recorded that the "musk" part of the name comes from a smell that the males spread on themselves during rut, but is not technically musk as they have no musk gland. She said that they have a preputial gland near their genitals that produce a strong smell, which they spread by their urine.

Ellen: It's similar in function to musk but Kirsten told me that musk from a musk deer is traditionally highly prized in its powder form to make fragrances. But if you tried that with a muskox, you would just get a stinky urine, basically. So as so often happens over time. The word musk just came to be sort of casually used for pungent animal smells, but it technically refers to a specific chemical compound, which the muskox doesn't make. Of course muskox does sound way cooler than stink ox, so maybe it's for the best. All right. Is there a better Norwegian name for them?

Kirsten: No, it's Moskusoske.

Ellen: Okay. Well, we tried.

Kirsten: And Moskusoske, it's funny. It's the name for muskox but when it literally translates, like if you were to run that through Google translate, sometimes it comes back as muskrat. So you'll be reading something about muskrats, but it's actually talking about muskox.

Ellen: Context clues would be wild.

Kirsten: Yes, exactly. A really cute one I saw recently it said musk, fairy which I love. And I, now that's how I think of them. I think of them as musk ferries, probably more accurate than muskox anyway.

Ellen: The petition to have it officially changed, begins here and now. Musk fairy, the absolute opposite of what a person typically thinks of when they think the word fairy. A massive lumbering ungulate is probably the vibe of the fairy mood board.

Kirsten: Right. But I think it's a sweet name. So that's kind of always in the back of my mind. So the muskox is actually more closely related to sheep and goats than it is to cattle.

Ellen: I can see that, especially with the horns. Cause a lot of goats with that sort of horn situation.

Kirsten: Yeah, exactly. That's kind of the big giveaway that you can tell that they're not related to cattle, the horn configuration, the horn moment that they've got going on is, uh, more sheep or goat, like.

Ellen: Yeah. Or like a big horn sheep, you know, I'm thinking of that too.

Kirsten: But even then it's a pretty distant relation. They're off in their own group. The scientific name Ovibos moschatus means sheep ox, musky.

Ellen: None. Correct.

Kirsten: Free word association when someone looked at one, I guess.

Ellen: Oh, I mean like if all you're going off of is vibes, you know, look at it and you probably aren't going to immediately think, oh, sheep and goats. There's a few other things that would come up first.

Kirsten: Yeah. It's I like that sort of vibe based naming convention. It's the way that people named birds, you know?

Ellen: Absolutely. And in the meanest possible way at every opportunity. Well, we're big proponents of vide based taxonomy here on Just a Zoo of Us. Just follow your heart, man.

Kirsten: I'm right there with it.

Ellen: Do they have the same kind of attitude that goats have? Cause when I think of goats, I think of pure attitude.

Kirsten: They can have attitude, definitely. Um, it probably depends on the time of year, they go through a rutting season, just like when people think of rut, they often think of deer. So this is typically late summer or in the autumn. When they're going through the mating season, the males will get some attitude for sure. They, um, become a little bit more aggressive. They'll start trying to establish dominance. They'll start fighting with subordinates or challenging each other. So that's the time of year where I don't want to get too close to a muskox. They can be a little bit temperamental. I don't want to get too close to them anyway, but especially not at that time so they can, they can have attitude.

Ellen: I feel that. So earlier we mentioned that all of the environments that they live in, whether it's in scandinavia or in North America, these are all like very cold, not just in winter, but like kind of all year round. Right. It's pretty frigid up there. So they have to be adapted to some pretty harsh conditions. I love to think about animals that have adapted to really hostile climate because you see some like, really, really cool ways that they have adapted their body to respond to that. And so I would love to take a look at some of those adaptations in the muskox. If this is your first time listening to this podcast, we rate animals out of 10 in different categories. The first category that we rate animals on is effectiveness, and this is physical adaptations that let it do a good job of the things it's trying to do. Let it survive in their environment. What do you give the muskox out of 10 for effectiveness?

Kirsten: So I'm going to go a little against the grain from what I've heard in past podcasts episodes, I would love to give a 10, I'm going to give a nine and I'm going to do that for educational purposes. So I can talk about why I'm not going to give them full points as much as I want to. So let me talk about all their great adaptations that they have for success and, and why I would like to give them a 10.

Ellen: Hype them up first.

Kirsten: Their range is typically the Arctic, the Norwegian population is actually south of the Arctic circle. It's a little bit different conditions there, but it's still Alpine Tundra. So it's still quite harsh. I mentioned earlier that they're very hairy animals. You can see in any picture of them. And especially if you look at pictures of them, when they are shedding in the spring, they start shedding their installation layer.

Ellen: I was wondering if they do that, because I think that our bison here do that too, right?

Kirsten: Yes.

Ellen: They lose that sort of fluffy coat.

Kirsten: Yes. So the muskox, if you go out into the fields where they live at the right time, you will just see clumps of muskox wool on the ground, caught on shrubs, I have some that I grabbed out in the fields. I have some muskox wool.

Ellen: Is it soft?

Kirsten: It is so soft.

Ellen: Oh my gosh.

Kirsten: Muskox wool -- so the, I really hope I don't butcher this name, but the muskox is a really important animal for a lot of indigenous cultures in the Arctic. And I believe it's the Inuktituk word, for muskox wool is _qiviut_. Not only is it incredibly soft, it is the most expensive wool in the world as far as I know.

Ellen: Really?

Kirsten: If you want to give yourself a shock, look up how much a muskox wool sweater or blanket, or even scarf costs. It is tremendous.

Ellen: Okay. The first thing that comes up is muskox wool socks. I'm going to EUUUGHH OH MY GOD --

Kirsten: Many people think cashmere is the most expensive, but I want to point out that there's only about 140,000 muskox in the world. So this is a, this is a limited resource they're only found in the high Arctic. And there are some that are raised in like farm settings, but not nearly enough to have any kind of commercial production. A lot of what you find that's made out of this wool is hand collected by people going out in the field and doing what I did and just grabbing clumps of it as you find it.

Ellen: Okay. So this price makes sense, right? For the materials. I'm looking at a pair. This is on Etsy. This is a listing for a 100% kevia lace or plain knit scarf. It is $350.

Kirsten: Yeah. It's not a joke.

Ellen: And, you know, once you say that, you know how labor-intensive and how scarce this product is, like, that definitely makes sense for that product. If you didn't know that though, and you just saw $350 scarf, you'd be like, I think not.

Kirsten: Yeah, exactly. And the thing is we were talking about their adaptations, this wool, not only is it extremely soft, it's like holding a cloud, but it is so warm that things like those socks and those hats and sweaters. You almost can't wear them because they are so warm. It's eight to 10 times more warm than sheep wool.

Ellen: Wow.

Kirsten: It is extremely warm, which makes sense because they live in these really harsh Arctic environments. And they don't hibernate in the winter, so they just have to withstand those temperatures.

Ellen: Just sticking it out in the coldest of the cold.

Kirsten: So they are bundled up. If I was going to get any sort of muskox wool accessory maybe a scarf, but anything more than that, I would not try to wear outside or I would have a heat stroke probably. I would overheat immediately. So they're, they're very well adapted to that for warmth. They've got this amazing insulation. They also have really sturdy hooves, for digging in snow in order to find food, they are not that effective at moving through deep snow. They have really short legs.

Ellen: Oh no.

Kirsten: If you look at a picture of a muskox, it's kind of funny how short their legs are compared to the rest of their body. They're not very good at moving through deep snow.

Kirsten: So they will move further up slopes where the snow is a little bit, or hasn't accumulated as much, but they can dig through snow and break through ice with their hooves, um, in order to find food in the winter time.

Ellen: I did look up a picture. Well, just so that I can see like the full body of the muskox and it does look like they have big like Clydesdale feet almost.

Kirsten: Yes. They actually bear a lot of their weight on the front ends. They've got quite wide and sturdy hooves.

Ellen: Like snowshoe hooves.

Kirsten: Yeah, exactly. You know, if you compare it to the other mammal that lives in the high Arctic, um, like the other big herbivore, which is the reindeer, reindeer have really sharp, tough hooves as well, but they're built for speed and they're built for, you know, they can dig through more deep snow, things like that. The muskox kind of went the other direction. They went for short, sturdy and tough.

Ellen: The muskox is the tank build? Reindeer is the DPS.

Kirsten: Exactly. I mean, they really are just built like tanks, to survive in that environment.

Ellen: I've heard that this is a thing, like a phenomenon where like the farther north you get the bigger animals get.

Kirsten: Yes. So I think a lot of this has to do with just metabolic needs.

Ellen: The context I was thinking of it in was in like wolves, for example, like the wolves that you'll find up north are like substantially bigger than the types of wolves you'll find farther south, that like further south you'll get wolves that are like smaller and thinner and lankier, but then up north you'll get wolves that are like bigger and bulkier, but that like a lot of animals that have that sort of wide range will be like huge in the north and then little down in the south.

Kirsten: Yeah. I think that's just due to heat retention and the ability to disperse heat as well.

Ellen: It's kind of the name of the game. Isn't it? When you're an animal.

Kirsten: So the muskox, there's one other adaptation that I think is really cool. And that's, if you look at a picture of their eyes up close, they have horizontal pupils rather than round ones.

Ellen: I love this!

Kirsten: They function sort of like sunglasses.

Ellen: Really?

Kirsten: So the horizontal positioning of the pupils helps reduce glare off of snow.

Ellen: Is that what that's for?

Kirsten: Yes. At least in the case of the muskox. That seems to be, uh, the purpose of that.

Ellen: Oh, wow. Cause I've, I've seen, you know, like goats that have that like horizontal slit pupil, and it definitely is strange to look at when you're up close with one in person. It has-- it gives you that sort of like alien looking sort of like feel to it when you look them in the eye.

Kirsten: Yeah. Goats do have that. Well it makes sense, because they're closely related. So it makes sense that they would have that similar configuration. Yeah. Yeah. It definitely is a little unnerving to look at.

Ellen: You know, when you said that, that it's for like reducing glare off of the snow, it reminded me of those sunglasses that are just kind of like, they're usually like carved out of bone and they're sort of like a visor over your eyes with the slits carved out. Have you seen those?

Kirsten: Yep. I think that's what that is, maybe not what it's based on, but it's the same principle. And they're used a lot by indigenous cultures. It's like a traditional way of reducing glare for hunters. So they have all these really cool adaptations that are really impressive for surviving one of the harshest environments that you can imagine. The reason why I didn't give them a 10 and the reason why I'm bumping them down a little bit is because we're living in a time of global change. Climate change in particular is affecting all Arctic animals to a really high degree. And for the muskox, this has impacts in terms of not being able to access their food, because rather than having snow, that they can access, you're having warming temperatures, which is creating snow melt and refreeze. So you get this ice crust rather than snow, that they can easily, um, navigate. And so it's much harder to access food underneath an isolator than it is under snow. And this affects animals like the reindeer as well. They're going to the same, same difficulty right now.

Ellen: Is there also an issue for them with the actual, just like temperature of the air in the sense that, like you mentioned that they're first so good at keeping them warm, which is great when the temperatures are falling really low, but as the temperatures are creeping higher, is that working against them as like, are you seeing like muskox suffering from like overheating?

Kirsten: Muskox certainly can overheat, you know, right now the population that I study is further south in Norway. It's not in the Arctic, so they are capable of living in some of those. So I'm going to say warmer, but warm is a relative term in this area. Um, they do live in a warmer environment than their Arctic counterparts, but they do have limitations for, for example, how much they can migrate because they are prone to overheating. That's one part of it. So I, I totally imagined that that is something they would find difficulty with if temperatures were to get too high. And the populations are pretty small. Like I said, there's only about 140,000, maybe less. Individuals in the world. And a lot of these populations are small isolated ones. There's not a lot of genetic variation. So their ability to adapt is definitely something that will work against them. And that's obviously not, I can't really fault them for that.

Ellen: Right. It's not their fault.

Kirsten: But they're definitely going to struggle to adapt in a changing environment. And especially as things warm or the climate changes, that's going to affect the way that people move and interact with the environment. And that's gonna affect human interactions with the muskox as well. So that is a concern I have about their ability to adapt.

Kirsten: Yeah. It's not a criticism, right? It is just a concern.

Kirsten: Yes, exactly. Otherwise 10 out of 10.

Ellen: Yeah, absolutely. I mean, if it weren't for us, they'd be perfectly suited for what they're doing.

Kirsten: Exactly.

Ellen: Hey there, we are going to take a quick break to hear from a couple of the other shows on the Maximum Fun Network. When we get back, we're going to talk ingenuity and aesthetics for the muskox. So stick around!

Ellen: Well, that brings us to our next category. You know, I'm wondering since maybe some things built into their body are starting to slowly work against them, you know, let's think about what are they doing? Like, what is their behavior like? The next category that we rate animals on is ingenuity, which for us is behavior. So things they're actually like doing with their body ways that they're solving problems or interacting with each other. Uh, what would you give muskox out of 10 for ingenuity?

Kirsten: I'm going to give them a 10.

Ellen: All right!

Kirsten: They do have some really cool behaviors.

Ellen: I'm interested to hear about this. Cause I-- no clue. You can tell me that they do calculus right now and I'd believe you.

Kirsten: Well, I'll tell you a story.

Ellen: Oh, I love a story.

Kirsten: And kind of frame this behavior. So like I said earlier, there was not a native population of muskox in Norway until the early, mid, nineteen hundreds. So. Now that you know, what a muskox looks like and bear in mind, they can weigh something like 400 pounds to 800 pounds.

Kirsten: I mean, they're big animals,

Ellen: chunky boys,

Kirsten: and their native range is in Arctic, Canada and Greenland. How are you going to move those animals, in the early nineteen hundreds, to Norway?

Ellen: That had not occurred to me until you said that, but now that you say that, that does pose an interesting dilemma, doesn't it.

Kirsten: So you have to go to where the muskox live. You have to find a way to capture them and get them onto a boat and transport them into the mountains somewhere else.

Ellen: Easy.

Kirsten: You're right. Yeah, exactly. So one of the challenges that people found when trying to achieve this was that muskox did not want to, they will not go willingly. I'll put it that way, so.

Ellen: Okay. I wouldn't either, but alright.

Kirsten: They have this really cool defensive behavior when they feel threatened. So a lot of animals, if you, if they encounter humans their instinct is to flee. Muskox are not built for speed. They can run surprisingly fast. They can run anywhere between 25 to 35 miles per hour, which is why you should not get too close to one in case they decide to sprint at you.

Ellen: I mean, it's a big animal. It's a lot of forward momentum.

Kirsten: They can't do it for very long. With their short little legs and their heavy fur and they'll overheat, but to compensate for that, they have developed these other behaviors for defense that don't involve having to run away. So, what they do is the more dominant members, typically the males in a herd, will start forming a ring around the young. The females will also join this, but the females are smaller. So sometimes they're also found in the, kind of more towards the middle with the young. And so they form a circle around the more vulnerable members and they have all their horns pointed out.

Ellen: Like a phalanx.

Kirsten: It's like an impenetrable wall of just mass.

Ellen: A fortress.

Kirsten: Yes. It's a living fortress. This works great against predators because the biggest predators that they're going to encounter typically in their Arctic distribution are wolves. So a wolf, even as pack hunters, they're not going to be able to breach that fortress.

Ellen: That's 360 degrees of coverage, baby.

Kirsten: Exactly. Those wolves will get injured. I don't know if they even will try in that case.

Ellen: Right. Just give up, find something easier, you know, like, at that point there's easier stuff to hunt.

Kirsten: So muskox are really hard to intimidate. I'll put it that way.

Ellen: Plus you have the audacity factor, right?

Kirsten: So that's a really cool adaptation to have against predators. You will sometimes see other predators attempt to take muskox like polar bears, for example, but they tend to go for individuals that are older or weakened in some way. Sick. You're not going to see many predators go after a healthy herd because they will just form that tight ring and be impossible to get through.

Ellen: That's so interesting. I'm going to see if I can, oh yeah. I typed in muskox and then the letter C and the first result that came up was like, muskox protective circle. That is really cool. I'm looking at a picture of it. It's very inspirational looking.

Kirsten: And it's organized looking, right?

Ellen: It is! Like, it looks like they should be charging into battle.

Kirsten: Yes, they absolutely do.

Ellen: They look very noble and majestic.

Kirsten: And it's just something that's so fascinating to me because when you think about animals, that exhibit herd behavior, you often think there's a threat. And so they'll start fleeing and they'll sort of flock together, safety in numbers, but they just band together and they organize this like beautifully symmetric circle of protection. I think that's a really amazing behavior that they have.

Ellen: I'm thinking about how you said earlier that like the males get so territorial and aggressive towards each other. And when you see a picture of them, like banding together to protect the herd, it feels like such a, like a lay down your arms, like solidarity with each other. Like, it just feels like such a, like a motivational thing. That's like set aside their differences. They're banding together and finding common ground and protecting their herd. Oh yeah. I could cry.

Kirsten: Their social interactions are, are so dynamic and they change throughout the seasons based on if there's young around, that changes the dynamic. Sometimes you'll get just bachelor groups where they were not able to establish dominance. You'll get just like some males or you'll get like a family. Maybe there's only five members in one herd, so it can vary quite a lot, but it's amazing the way that they've found to, to protect themselves and each other.

Ellen: I feel like when I look at all these pictures of them and it's usually like, the snow is blowing around them, like, of course --

Kirsten: It's dramatic.

Ellen: Their hair is blowing in the wind and there's like a flurry of snow -- I feel like, like you can hear the picture. It's like looking at the picture you can hear the dramatic theatrical score, swelling in the back.

Kirsten: They make for some of the best dramatic photos.

Ellen: Incredible, absolutely stellar.

Kirsten: It's just amazing. So this strategy that they have of banding together works great, but it makes it difficult when your adversary I'll say is human hunters, because they can find ways around that defense. And I believe, some of this is not recorded. So it's like an oral history, but some of the stories I've heard about how they tried to re-establish muskox populations was that they couldn't catch the big strong adults. They would try and catch only the young. At one point they were barred from like hunting family groups like that and taking just the young and like breaching those circles if they formed them.

Kirsten: So some of the techniques involved, like hurting them towards the sea for example, to like break that formation and try and collect individuals to bring back the reintroduction actually took several attempts. And part of this is because the muskox are quite used to being the only big herbivore in their environment. When they moved here, where you have sheep and other deer, for example, things like disease would spread and make it difficult for them to survive. And a lot of these animals are used to the Arctic Tundra where it's a little bit flatter and they were introduced here into the mountains, where there's avalanches, which is something that they were not as prepared for, for example.

Ellen: I'm so not used to this, like a snowy mountain area that I forgot avalanches existed until you said that word.

Kirsten: So right. And these animals have never encountered these before. And especially since a lot of the reintroduction was focusing on bringing young individuals over, they didn't have the adult family members that can sort of guide them through different scenarios. And so they struggled to make it through some of those winters and these like different conditions. Now that population is over 200 individuals, it's maintained at that number. I think the fact that this population managed to grow after so many initial setbacks really shows their, I guess I'll say ingenuity and their ability to learn and adapt to those scenarios because the population started at just a handful and then World War II happens and they were wiped out. During that time they were, they were hunted, um, because it was a tough time. There was scarcity. And so they had to be re-introduced again, um, after World War II.

Ellen: After all that hard work.

Kirsten: Yep.

Ellen: Start from zero.

Kirsten: Had to start from scratch. Um, and so they had to bring more over to start that population. And since then that population has only grown and some have actually migrated. There's a handful. 10 individuals I believe that broke off from this population and moved to Sweden.

Ellen: Do you think there was some drama in the herd where they were like, "you know what, forget you guys, I'll start my own herd."

Kirsten: They crossed the border over to Sweden and Sweden was like, "all right, we're the muskox country now."

Ellen: I mean, what are they going to do? Turn them away at the border? It's a muskox. Like, what are you going to do? You can't tell them no.

Kirsten: Exactly.

Ellen: They'll like charge right through the little, uh, the arm thing, but yeah, you're not gonna stop that.

Kirsten: You could not stop that muskox that wants to cross.

Ellen: There's no border patrol for the muskox. They recognize no borders.

Kirsten: But it's really funny because in Norway they're actually a black listed species. Um, so this is a status that has given to species that are invasive and that are not allowed. So, I said earlier that this population is kept at a maximum of around 200. Last I checked, it was something like 240 individuals. So it's a little bit over. But they try and keep this population fairly low. And that is to reduce things like competition with the native species, like reindeer that they share that area with just reduce grazing pressure on the mountains. I don't think they envisioned having that problem when they moved this handful of muskoxen over.

Ellen: Right, because it feels so like, all right, you guys are doing great now do less great.

Kirsten: Yeah. So try and keep it under control now, you know.

Ellen: Stop, stop, stop too much, too much, too much.

Kirsten: Yeah. There's a highway that cuts through the national park where they live. Um, it's the Dovrefjell -Sunndalsfjella national park. And they're only on the west side of the highway. They're not supposed to go over the east side. If they cross the east sides, then I think, . Um, some management agency gets involved because they don't actually want them to spread beyond their designated range.

Ellen: That is a very specific demarcation. It's just like, you shall go no further, do not cross the street.

Kirsten: It's okay to go the other way to Sweden, but--

Ellen: Then they're like, you can go be their problem.

Kirsten: I just thought it was so funny that they introduced this species that they really wanted to be like this new national symbol. It's the emblem of Dovre of that municipality down there. They have that on their coat of arms, I guess I'll say, is a muskox. So they're quite proud of their muskox, but they say don't, don't get carried away.

Ellen: And it was like a, okay. We want to keep him special. We don't need too many of them. We don't want them to inflate the value, what a charming problem to have.

Kirsten: Yeah. So I think they're, they're an amazing species.

Kirsten: I, again, I'll give them 10 out of 10 for ingenuity because of their social behaviors and how they have managed to thrive in this area that they weren't used to is quite an achievement.

Ellen: For sure. And they're beautiful. They're so cute.

Kirsten: Yes.

Ellen: Let's talk aesthetics. The last category that we rank animals on is aesthetics, which is pretty self-explanatory. It's just, how nice is this animal to look at? What do you give the muskox out of 10 for aesthetics?

Kirsten: It has to be a 10.

Ellen: It has to be right?

Kirsten: Is there anyone who would say otherwise?

Ellen: That's a big fluffy puppy dog.

Kirsten: If anyone is in doubt, I would encourage them to Google image, search a baby muskox.

Ellen: Let's do it.

Kirsten: And try not to cry.

Ellen: You're going to get a live real-time muskox baby-- you're kidding! The first picture that comes up is, has this little foot up and it's very proudly marching.

Kirsten: They are the cutest babies in the animal kingdom, and actually my desktop wallpaper is baby muskox because whenever I feel overwhelmed with my work or I'm like working too hard, writing my papers, um, I can minimize it. Look at the baby muskox. Recenter myself.

Ellen: This is a self care, like looking at pictures of baby muskox I think is a self care item. Like . I feel like, uh, like therapists should start prescribing images of baby muskox. Muskoxen?

Kirsten: So it's, I think technically it's muskoxen, sometimes I'll use muskox and that's, I think it's because of Norwegian, they just say Moskususke. And so I got in the habit of just saying muskox for all of it.

Ellen: It's what I'd be doing.

Kirsten: I kind of go back and forth, but I think muskoxen is technically correct. Yeah. They're just incredible to look at. And if cuteness, isn't your thing and you want something dramatic lookup, muskoxen, and winter, and just see their like windswept, beautiful-- standing in the mountains, their hair blowing back. Just stunning.

Ellen: Very tormund from Game of Thrones.

Kirsten: Yes.

Ellen: It's definitely Freefolk.

Kirsten: Yeah.

Ellen: It's very good. It's also a little bit Hoth.

Kirsten: Absolutely. Absolutely.

Ellen: Yeah. And as much as we want to fawn over how cute the babies are, they don't lose that energy.

Kirsten: No, they keep that through adulthood.

Ellen: They still have that big, I love, a big, broad, like snout on a, on a pig. It's what I find cute about cows. Like, yes, just the big soft muzzle.

Kirsten: It's definitely that vibe.

Ellen: And also knowing that they're soft like that they're actually soft to touch because sometimes you look at an animal and you're like, it looks soft, but I bet it's really not. But like, knowing that they're soft brings me a lot of inner peace.

Kirsten: Yeah. Their, their wool is incredible. Like I've been sitting here with this piece of wool in my hands. It just stays on my desk. It's like a, like a stress ball almost.

Ellen: Does it make a sound? Do they make sounds?

Kirsten: They do. So the adults, you'll sometimes hear the males before you'll see them in the rutting season. They have sort of a roaring rumbling sound.

Ellen: Roaring! That's cool.

Kirsten: It sounds kind of prehistoric. Like if you try and imagine what a wooly mammoth might sound like. They kind of remind me of that. Just scaled down.

Ellen: So if anybody out there is a filmmaker and is looking to incorporate some really cool, like fictional animal sounds look into the muskox.

Kirsten: And the babies, they bleat kind of like goats.

Ellen: Of course they do. Right?

Kirsten: And it's really cute.

Ellen: Oh my gosh. I just, I'm thinking of those little goats that make like the goofiest sounds. Like the videos where the goat's like, BLEH, which is way funnier when you imagine it coming from an even larger and more intimidating animal.

Kirsten: Right. The first time I saw the muskoxen, it was a family group that had two calves with them and it was just perfection.

Ellen: Blissful.

Kirsten: It was so, yeah, it was like sitting there in the mountains, watching them graze and rest, ugh and watching the little ones run around. It was so cute.

Ellen: Here's one minor aesthetic issue I'm having. And it is that I have now come across pictures of them actively shedding.

Kirsten: Yes.

Ellen: And that's not great.

Kirsten: Luckily that's only part of the year when they start shedding that winter coat.

Ellen: That is unsuccessful.

Kirsten: That's when they look like the Banthas, that's when they're channeling that Bantha energy.

Ellen: Like ghosts is what they look like. They look like a banshee, like a zombie version.

Kirsten: Yeah, that's true. They are not that beautiful when they are shedding.

Ellen: At least. I mean, listen, we all have our days where maybe we're having a breakout, maybe like, you haven't washed your hair. Like we, I will grant them. You know, everybody sometimes has an off day. That's maybe not the most flattering angle for them all other times, if you've ever groomed a very, very fluffy, like a Husky or something, and you take like the de-shedder thing to a Husky and you're just like pulling out sheets and sheets of fur. But it doesn't make the dog look any less furry, you're getting all this fur but you're like, nothing's happening. Where's it all going?

Kirsten: I think muskoxen um, when they are shedding like that, they lose something like five kilos of hair, which I'm not good at math, but I think that that's something like 12 pounds. It's a lot of hair.

Ellen: That is like my whole dog of

Kirsten: hair lost.

Kirsten: And you only need, so if they shed 11 pounds of hair, you only need something like a hundred grams of it to make a sweater.

Ellen: So it is efficient.

Kirsten: Yes.

Ellen: I feel like it would be nice to like, feel it just to experience the softness of it, but that is a very high investment.

Kirsten: When I'm out in the field, I'll just, because I am one of those people that goes out in nature and has to like, touch everything and like puts random things in my pocket.

Kirsten: So I'll grab some of this. Cause it's, it's all over the branches, especially this time of year, I'll be able to, there'll be start shedding. So I will grab some and we'll see if, if mail gets stopped, but just has like,

Ellen: "Wait a second..."

Kirsten: random hair in it.

Ellen: And it was $70 worth of fluff that you're trying to send in the mail.

Kirsten: Yeah.

Ellen: Insure this. I would love to feel one someday. They look beautiful and soft. What a spectacular animal. And, and it makes me surprised that I guess, because it does live so far up north and it doesn't have a very southward extending rain range, I guess it doesn't surprise me that not a ton of people know about them. Like, I couldn't even tell you if I've ever, I've never seen one in a movie.

Kirsten: Right?

Ellen: Like maybe in a nature documentary somewhere, but I could not tell you any depiction I've ever seen of a muskox.

Kirsten: Yeah. And now I think of it. I don't think I've ever seen them in pop culture either. I do believe that the Bantha and Star Wars was, it has to have been inspired by the muskox. But other than that, I don't think, I can't think of any, any example in culture.

Ellen: I Googled it and Discovery Channel posted on Instagram that muskox were one of the inspirations for the Banthas, seen in Star Wars.

Kirsten: Oh, there we go.

Ellen: And that's from Discovery. I don't know where they got that information, but that's what they said.

Kirsten: I'll take their word for it.

Ellen: Yeah, I mean, they got the blue check and everything, so they must be right.

Kirsten: Yeah, absolutely.

Ellen: Beautiful. Well, as we're getting wrapped up with the real life Bantha, the muskox, for today, let our folks listening at home know, like, what are you up to now that people can follow along with?

Kirsten: Well, I am working on two projects right now. One of which of course is my master's thesis. So my research is studying the diet overlap in the Dovre mountains between reindeer, sheep and the muskox to see if there is, um, any seasonal overlap there. And, um, I'm also working on a collaboration through the UArctic Sematic Network on herbivory , where we are working on a field ID guide for pellet sampling. And so, um, I am currently working on that. We'll be launching that soon. You can find me on Twitter at @reindeerist. So that's just reindeer, I S T on Twitter and that's where I will be posting mostly about my research and the upcoming project with the herbivory network. And lots of pictures of Norwegian wildlife. That's mostly what I've been tweeting. So if you want to see pictures of Norway and Norwegian wildlife, then, uh, my Twitter is the place to be.

Ellen: Awesome. And I'll have links in the episode description. So anybody who wants to follow along with your work and check out some adorable baby muskox can just scroll down and click on through.

Ellen: Perfect.

Ellen: Awesome. Well, thank you so much for your time and your knowledge and your love for muskox that I think we have probably left some people with here today. Like if the baby muskox, isn't going to do it, like nothing's going to do it. It's--

Kirsten: Absolutely. I mean, come on. Just look at them.

Ellen: If the baby muskox doesn't break through the glacier of your heart.

Kirsten: If it doesn't ignite something...

Ellen: Yeah, like that's going to do it. Um, so thank you so much for your time and teaching me about muskoxen. And now I feel like I love and appreciate them so dearly. So it has been a delight. Thank you so much. And we will talk to you later.

Kirsten: Well, thank you so much for having me. It was great talking to you.

Ellen: Of course! Thanks, bye.

Kirsten: Bye.

Ellen: Thank you all so much for listening friends. I hope that this episode gave you a feeling in your heart as warm and fuzzy as a baby muskox.

141: Bigfoot w/ Elliot Helmer!

Ellen: Hello friends and welcome to episode 141 of Just the Zoo of Us! This week, I am joined by an archeologist and cryptid enthusiast to search for the truth about our most mysterious neighbor Bigfoot. We talk about hominid evolution, cryptid ecology, the importance of oral history and traditional knowledge, and what Bigfoot can teach us about ourselves and our own relationship with nature, wherever you fall on the spectrum of skepticism. This episode is pretty different from what we usually do here on the show. And that is because it's a special occasion. This is the Max Fun Drive. It's the time of year when all the podcasts on the Maximum Fun Network focus our efforts on going above and beyond to ask for your support. This show and the others on the network are artist owned and listener supported, meaning that your contributions keep us going. You can be part of the Max Fun Drive and join now at maximumfun.org/join. I will be back in a little while to tell you more about what that means and what's in it for you. But first, Just the Zoo of Us presents: Bigfoot with Elliot Helmer.

[intro music]

Ellen: Hey everybody! It is Ellen Weatherford, I'm here with your favorite animal review podcast, Just the Zoo of Us. This week, with it being the Max Fun Drive, we have something really exciting and super different from what we usually do, but something a lot of you have been asking for. So I think you're really gonna like it. This week we're [00:01:30] joined by a new friend, this is Elliot Helmer. Say, hi, Elliot!

Elliot: Hello everybody.

Ellen: I'm so excited to be talking to you. We've been talking, chatting back and forth for a while, and I'm really excited for this episode because it's super different from what we usually do, but I think it's going to be great. And I think everybody's going to love it. Elliot, you're here to talk about a cryptid, which is something we haven't tackled on this show before, but this should not be the only time we talk about cryptids on the show. So opening the door to cryptids on just the zoo of us. So before we talk about our cryptid friend today, let's talk about you a little bit. Elliot, what got you into studying Bigfoot? Like what, how did you get here?

Elliot: Well, Bigfoot is more of a hobby for me. Technically, I'm an archeologist that studies shellfish procurement and the relationships between people and land. But in my free time, I am deeply obsessed with cryptids generally, Bigfoot especially because he's kind of, you know, the poster boy of cryptids.

Ellen: This is THE cryptid. If you've heard of a cryptid you've heard of Bigfoot.

Elliot: Exactly. And it's actually not totally out of left field because I am, I'm an archeologist, and in the United States, archeology is a sub field of anthropology, which is the study of people, but also non-human primates. And so Bigfoot being a non-human primate fits right in with anthropology. And there's actually lots of anthropologists that publish about Bigfoot and have published about Bigfoot. So it might seem sort of out of left field, but [00:03:00] really it's it's right at home. It's my own little side project within, uh, within anthropology.

Ellen: Yeah. What got you interested in Bigfoot? I know you said this is kind of like a personal interest for you. Where did that come from?

Elliot: I've always been one of those little kids that was really into like fantasy stuff. You know, I read a lot of fantasy books. I read a lot of, you know, like the Spiderwick Chronicles and other things where like a little kid goes and finds like magical creatures. That was like a dream. And so I sort of just got into Bigfoot through that general interest in like fantasy creatures, and sort of as I've grown up Bigfoot and cryptids specifically have been something that's really stuck, like my main interests, moving beyond like kids fantasy stuff, just like Bigfoot culture, Bigfoot aesthetics, the culture around like studying Bigfoot and finding Bigfoot, I think is very interesting.

Ellen: It's that element of mystery, right? Like you get that in fantasy media also, but it's that feeling of like wonder and mystery and something being beyond our comprehension that you get just in real life.

Elliot: Yeah. And it's not like there's like some fantasy stuff that's like, there's dragons or this person like, can do magic spells. Whereas like Bigfoot, I feel like could really exist out there in the real world. And so it's like that fantasy thing that you can bring to your everyday life of like, wondering is it, or isn't it, it's not like, you know, dragons or mermaids or something that seem a little bit more fantastical. It's like this could really be here.

Ellen: It may be a little bit different if Bigfoot perhaps had magical powers. Yeah.

Elliot: Yes. Like if [00:04:30] Bigfoot could like teleport and fly and although I was gonna say control the weather, although there are some original indigenous stories about Bigfoot where he can control the weather. So Bigfoot has a lot, a lot to give, like he has a lot to give.

Ellen: But in terms of just like a big guy, that's just like in the woods, that is completely within like the realm of, well, yeah, there's big guys. Sometimes.

Elliot: His core, he is just a big guy that lives in the woods. And even in like, one of the more popular depictions of Bigfoot is there's a, or it's not about big foot, but there's like a X-Files episode about like the Jersey devil and they, they literally just make it a guy in the woods. It's just a guy in the woods and they talk about Bigfoot in that episode where they really are just like, " it's just a guy. He's in the woods."

Ellen: It's just a guy, he's out there.

Elliot: And like that --there are guys in the woods!

Ellen: All the time.

Elliot: One of them could be Bigfoot.

Ellen: This is totally within the realm of plausibility and familiarity.

Elliot: Yes, yeah. Feels much more tangible.

Ellen: With that being said, sometimes people refer to Bigfoot as, like we said, a guy as in, like, there's just the one, like I'm thinking of like a legendary Pokemon. Like there's just the one Bigfoot, but I've also heard people talk about Bigfoot as like a species like, that there's multiple Bigfoot, Bigfeet, Big's Feet, Bigfoots.. So like what, what is Bigfoot? Is it just the one Bigfoot or is there like an idea of there being lots of them?

Elliot: I have [00:06:00] always thought of it more of there being lots of Bigfoots, is how I'm going to go with the pluralization because Bigfeet just sounds weird. But I think that it's like, especially if you're thinking about Bigfoot more as like a tangible animal, like something that exists in like that could exist in the real world, it makes more sense for there to be multiple because otherwise then you would have to accept that there's one Bigfoot that has been alive since like the forties. And like somehow ends up all over, like, the Western seaboard and like into like, the Midwest. Like if you're thinking about Bigfoot as like something that really could exist, you sort of have to like accept that there's multiple, like this is a species that does have that longer extent they can be around for generations and generations. It's sort of like if you are envisioning it more as like a tangible creature, rather than like a fantastical creature, it kind of needs to be a whole species, rather than just one immortal Bigfoot.

Ellen: Unless, Parthenogenesis is involved.

Elliot: It's true. There could always be one at a time.

Ellen: It's just the one Bigfoot that is self-replicating, and then it'll be a clone and Bigfoot would be a female of their species that would be capable of reproducing via parthenogenesis.

Elliot: That's possible! I haven't really thought about the parthenogenesis aspect, but then you would still have to believe that Bigfoot can like really get around, like really be moving. Like people are citing him in California. They're citing him in like Southern California. Like, how'd you get from Washington to California so quickly with just one guy? But I don't know. [00:07:30] He's got big feet, long legs.

Ellen: There you go. His stride is so long he can cover distance. It's true.

Elliot: And there are like physical anthropology papers about like Bigfoot stride. And like what based on like Bigfoot footprints, what was his, what would his stride be like? What is his gait like? So there's research out there.

Ellen: He's really getting around. Okay. So with that being said, when we say that he is a cryptid, like how do you define what a cryptid is?

Elliot: So the technical definition of cryptid is an animal whose existence is disputed, or it can also include animals that exist in places they shouldn't be, there are like stories about like big cats, like Panthers and stuff on like the moors in England. Like, and those are considered cryptids, it's because the existence of that animal in that place is disputed. And like, we don't really know for sure if that animal is real. Cryptozoology then is the study of cryptids it's the study of these, maybe or maybe not real creatures, which sort of distinguishes like Bigfoot and like cryptids from things like leprechauns, which is like not an animal so much, or like it distinguishes it from like aliens. They're sort of in the same --people lump them together. But technically aliens wouldn't be cryptids because it's not, they're not like animals whose existence is disputed, they're like a whole extra terrestrial. But what's interesting about cryptids is that there are a lot of cryptids that are no longer cryptids because their existence has been confirmed. So I know you've talked about the okapi on the show before, and it [00:09:00] used to be that the okapi was a cryptid and that's really like, that's the cryptozoologist like favorite thing to talk about is like, well, did you know that the okapi was a cryptid? And then they discovered it was real. So it's possible for all cryptids.

Ellen: It does lend that element of plausibility to it. That's like, well, you know, this has happened where we thought something was fake and it wasn't.

Elliot: Exactly. And one of those things is that, for a lot of the cryptids that have had their existence confirmed, when you're saying its existence is "disputed" really you can sort of think of that as its existence is disputed by like, white people and Western science, because like the okapi, the people that live in that area and knew the okapi existed, they told people the okapi existed. And that happens a lot. Is that like native people will say, yeah, there's this animal that has zebra legs, but like a deer head. And it's like, "oh that's not real", but just because you haven't seen it, like the native people are telling you, like, yeah, I know that that's there. Why don't you believe me.

Elliot: There's this great paper about Bigfoot that I'll probably discuss later by this anthropologist named Wayne Suttles who worked in like the Puget Sound and Southern British Columbia area. And he talks about how, like, if you listen to somebody describe what a beaver is like, "oh, it's this giant rodent that can cut down trees and build dams and communicate with other beavers through like sound" like that doesn't sound real, a rodent that can cut down trees and build dams, but beavers are real.

Elliot: And he like described that as like you can't just, based on their description of it outright, [00:10:30] say that something isn't real. Like I think the way that he phrases it is like you can't use ethnography, which is basically the study of contemporary people, like a detailed study of contemporary people. Ethnography can't disprove beavers anymore than it can disprove Bigfoot.

Ellen: Reminds me a lot of the Platypus, how early Western scientists saw Platypus and were like, surely not, this can't be right.

Elliot: I mean, there's a lot of, like, one of my favorite things is looking at like old medieval illustrations of like animals that like, lived in like Africa and stuff. Like the first time that they heard of a hippopotamus. And they're like, I guess, I don't know how to draw this. And then you see these absolutely ridiculous drawings of what they think that it might be basically the world used to have many more cryptids before white people got out and identified everything. They used to think like, people in Europe are hearing about people discovering giraffes and they're like, no. That can't, that can't possibly be the case.

Ellen: You've made this up. This is a farce.

Elliot: Yeah. And so now the thing with cryptids is that, you know, we've discovered the whole known world. We know we've mapped the entire globe. And so the question then being like, what's left to discover, but we know that like we're constantly making new discoveries in, especially like the deep sea, they're finding new species of like snakes and bugs and stuff like that. So, you know, there's always the possibility for discovery, even though we think we've discovered everything in the world, things are much more diverse than we expect or give credit to.

Ellen: Yeah. Another famous example, since you mentioned the deep sea, you know, coelacanth, that was just [00:12:00] chilling the whole time.

Elliot: It's crazy. Like there's stuff out there you, you would never, never think to describe. And like, you know, there are parts of the world outside of like the United States where everything is very developed, right. Where there is a lot of forest that hasn't been explored or, and it's one of those things where it's like, well, maybe the native people are telling you that something is there, and all this time, we haven't been believing them. So anyway, I think that there, something about cryptids that's wonderful is just the idea of like there being things left to explore and there being mystery, it almost sort of like goes with that idea of scientific discovery where like people love science because they love the idea of discovery and learning something new. And I think that cryptids is really lend themselves to that. Just like to the extreme.

Ellen: Are Bigfoot and Sasquatch, the same thing?

Elliot: Sort of, so Sasquatch specifically is a word that comes from a Coast Salish language specifically, it comes from Halkomelem, and Sasquatch comes from the Halkomelem word saesq'ec, which the direct translation isn't really clear, but saesq'ec refers to a giant, hairy man that lives out in the mountains, basically, which was a figure in like Coast Salish like zoology. Like when you're asking, when, again, Wayne Suttles, this anthropologist that worked with the Coast Salish, he would give them books of like, here's a list of all the species in Washington, all the mammals in Washington, give me the translation for all of these species and they would go through and say, "Oh you're missing a couple of species." and they would say like, well, you're missing, you [00:13:30] don't have Sasquatch on here. You don't have these other, like these, this two headed snake you don't have on here. And so Sasquatch comes specifically from the Coast Salish language and from like Coast Salish worldviews, but the Bigfoot is often used much more generally to refer to like how Bigfoot manifests in lots of cultures. Like obviously people in like California, aren't speaking this British Columbia language, but they still have like a giant hairy man that lives in the woods. They just call him something different. So Bigfoot and Sasquatch are pretty much the same thing. It's just a difference in etymology. But then there are also large humanoid primates like that, that live literally all over the world.

Elliot: These are stories that come up literally everywhere. And so Bigfoot and Sasquatch usually just ends up referring to the ones that are in North America. Whereas, like you mentioned, like Florida has skunk ape, Australia has the Yowie. Indonesia has the Orang Pendek, which translates to like short person, which is basically like, like a smaller version of Bigfoot. And then obviously there's the Yeti in the Himalayas. Right? And so these are all functionally the same as a giant hairy man that lives out in the mountains of the woods. But nobody would refer to those as Bigfoot, Bigfoot's really like a North American phenomenon. And I get very heated with people that are trying to say "well, I heard that I saw big foot in like Ohio!" And I'm like "no, Bigfoot lives on the west coast. Bigfoot is, it is a species with an actual range that lives in the west coast. I don't know what you saw out in [00:15:00] Ohio, but it wasn't Bigfoot. But no, that's our cryptid that was here. You can't just totally destroys the credibility of Bigfoot to just say you saw it wherever you want.

Ellen: We are cryptid gatekeeping.

Elliot: Exactly. Like people are like, "oh, I saw Mothman" and Mothman is a different cryptid, but Mothman was like cited in like Cincinnati or like Chicago or something a couple of years ago and I'm like, "No. Mothman is West Virginia's.

Ellen: Right, like specifically Appalachia.

Elliot: You can't take that kid, you can't just say that you saw Mothman in Chicago, you have your own stuff going on in Chicago. Don't be taking other people's cryptids. So it's actually like a whole other cryptid in like that area, like in Wisconsin, Illinois, Michigan, which has Dogman, which is its own whole thing. So why don't you just stick with your cryptids?

Ellen: Okay. You got your own interesting stuff going on. You don't need to branch out, let us have this!

Elliot: Which I also think sort of goes to that idea of like, if we're talking about Bigfoot as an actual tangible animal, it has to have like a range. You can't just live everywhere. Like if you are talking about it as a thing that could exist it needs to have a specific range. And I think that range would be west of the Rockies.

Ellen: When you were describing the variations of what we consider to be a Bigfoot-like creature that occur all over the world, you know, when you're talking about like Yeti or the smaller one--

Elliot: Orang Pendek!

Ellen: Orang Pendek reminds me of orangutan.

Elliot: It's the same etymology. So orang means [00:16:30] person.

Ellen: And you're describing like them having very noticeable, physical differences between them. Like one of them being much smaller. It reminds me of like the variation you see in species, maybe like a genus of species that occur over a wide range where some of them might be much taller than the other. Some of them might have more hair or less hair or be skinnier. It'd be bulkier. You see that in, you know, genuses of animals that live over wide ranges. So like you said, if we're applying Bigfoot lore to tangible real-world species, it makes sense that they'd have a wide range with physical variation to adapt to different environments.

Elliot: And something that's really interesting about the Orang Pendek. It's the same sort of thing. It's a hairy humanoid, lives in the mountains. What's really interesting about that is that there is a species of hominid, homofloresiensis, which is a human, not a human ancestor, but a human relative from the past that is from like the Indonesia Sumatra area that was a very, very tiny human, basically. Like when they were discovered, like those fossils were discovered around the same time that the Lord of the Rings movies were popular. So they're often referred to as the Hobbit, like they're the Hobbit species. So I think that there's probably this like connection between this idea of these very small people, the homofloresiensis that sort of carries through this Orang Pendek thing, which speaks to the fact that before like 40,000 years ago, there were multiple species of human that existed on the planet at the same time. [00:18:00] And so it's interesting to think that maybe that like manifestation of Bigfoot could be this, like, hold over like cultural memory of those smaller people, because we don't know exactly when homofloresiensis went extinct. We don't know how much of an overlap there is with modern humans. So these sorts of things can be like carried over, like through generations and generations, these stories, which I think is really interesting. It's really impressive what we, as a human species are capable of maintaining just through like oral histories and learned like cultural beliefs that just persists for like thousands and thousands of years.

Ellen: Right. Cause that's like an element of our natural history that just gets passed down, even though that's so far removed from what anybody on our living on our planet would remember.

Elliot: Yeah. The tribe that I work with in Oregon has stories of like rhinoceroses that like lived like an Oregon. And then there has been like evidence of potential, like Pleistocene, like ice age megafauna, like these giant species that like existed way, way back when, and there's like a thought that the stories of the rhinoceros could just be this hold over cultural memory from way back when. And so I think that there's something to be said about like this widespread belief in Bigfoot or other large non-humans and the idea of this cultural memory that we have of there being other species of humans. Like it's very unnatural in terms of like the grand scheme of human evolution, for us to be the only species of our genus all alone in the world. [00:19:30] Whereas up until 40,000 years ago, which is when the neanderthals went extinct, there were multiple species of human. And I think that part of why Bigfoot is so widespread is that we're kind of lonely, you know, as a species, like it's very rare for species to be just the one species in their genus. It definitely happens. You talked about different species like that on the show. But I think that like part of it is that, you know, we're kind of lonely. So we want to invent our relatives or people that are just, that are like us, but not like us. Um, because it's not natural for us to not have millions and millions of years there were multiple species of human. So it's not our natural state.

Ellen: Yeah. And believing in there being still existent members of the human genome would I think, feel like a connection to nature as a human, like humans so often see themselves as being separate from nature. But if you are still thinking about, oh, we have relatives that descend from the same line of early, early humans that are still here, it just makes you feel more like understanding your place in the animal kingdom a little bit more than just if you're thinking of like our human relatives as being like Bonobos or chimpanzees or something that seems more farther removed, but then that might feel a little bit more distancing between you and the rest of the animal tree. But if there's a little bit more of a bridge there, you can know that feels a little bit more like a connection.

Elliot: And like historically there was a bridge, like, I mean, we co-existed with Neanderthals [00:21:00] for thousands of years in Europe. And we know for a fact that we were breeding with Neanderthals because almost all humans have some small percentage of Neanderthal DNA. Like, these other species of humans were something that we interacted with and had relationships with. So yeah, like the idea that Bonobos being our closest, like relative, but still feels very distant because it's not the same kind of relationship that we were able to have with the other members of our genus. I've even heard, like people call like Bigfoot or Sasquatch, homo-sasquatch-ensis, to try to like give it that sort of like species place. But I think what you said about the idea that we're very, I think humans are very concerned about like where we fit into the world, where we fit into the animal kingdom. And there's like a long history of like Western civilizations and like Europeans thinking like, well, we fit into the animal kingdom by being on top of it. We're going to dominate nature. We're like different from nature and we're in charge of. Whereas most cultures outside of like Europe didn't see it that way they saw maybe they were apart from nature, but at the same level as other species or that there was no difference between us and nature at all.

Elliot: And so I think that the other thing about Bigfoot being so widespread is that we're very obsessed with like fitting ourselves into nature and deciding like where do humans fit in the grand scheme of thing? What makes us different from all the other species? Because obviously we are different. But how and why? And I think that having that sort of foil in having these sort of Bigfoot like stories all [00:22:30] across the world is sort of our own way of dealing with where do we fit in? What makes us different from nature? And what would it look like if maybe we weren't as different from nature? You know, getting philosophical about Bigfoot?

Ellen: Well, I think that's what Bigfoot brings out in people. You know, I think that makes people feel very introspective and feel very, like, philosophical about like, what does Bigfoot mean to me?

Elliot: It's a big question, he's deep in my heart and my soul.

Ellen: Yeah. I think he brings that out.

Elliot: Yeah. And like I said, humans are obsessed with this. There's hundreds of papers in anthropology and archeology justify, like about like when did we become human? Like when can we trace humanity back to. We're obsessed with ourselves in that way. And so Bigfoot sort of fits into that larger scholarly tradition. Like, as I would say.

Ellen: You know, since Bigfoot is such a special case and he's very different from the animals. We typically review on this show. If you're, if this is your first time ever listening-- this is a very strange episode to get in on if this is your first one. But we like to rate animals out of 10 in different categories. But since Bigfoot is very different from the animals, we usually talk about, we wanted to do something a little bit different because we didn't feel like the categories that we typically apply to our animals were going to work for Bigfoot and what we know about him. So instead we're branching out a little bit and we've got some custom categories that we're going to [00:24:00] rate Bigfoot on. Um, the first of which is plausibility. So for plausibility, we're using this rating to express how much you believe in your heart, that Bigfoot is physically present out there, kicking it in the woods in the sense that like you could go there and see and touch a Bigfoot. Um, what would you give Bigfoot for plausibility?

Elliot: In my heart and my soul I want Bigfoot to be real so badly, but I think that I'm going to give Bigfoot a four for plausibility.

Ellen: That's something.

Elliot: There's, you know, some convincing evidence. But I think that, like give some real justification for why I think that, I'm going to give like a little bit of like ecological background on what, what a real Bigfoot would be like in the world. And why I don't necessarily think that you can really give him more than a generous four in terms of tangibility. I briefly mentioned this idea that Bigfoot, hairy bipedal non-human primate, lived sort of in the mountains of like the Western United States. This is like a huge animal. So this isn't like, you know, we discover new species of like insects all the time. This is a giant species that we have somehow not seen.

Ellen: It's hard to miss.

Elliot: Or at least, you know, people have seen him, but we don't have, like the tangible proof, the average size-- and I'm going to give you some stats that I got from the Bigfoot field researchers organization. [00:25:30]

Ellen: Excellent.

Elliot: And so they've compiled a lot of information about Bigfoot sightings. So, I mean, this is a on average, six to seven foot tall animal. It's well, within the range of human existence, although there are cases where people said that it's up to 10 feet and I actually had a really interesting conversation with the man that runs the Bigfoot discovery center in Felton, California.

Elliot: He thinks that most of the Bigfoot sightings are underestimating how tall Bigfoot is, because he thinks that the Bigfoot that we see are probably young, stupid Bigfoot that are like wandering out into like the roads and like getting close to people because they're like curious and young. And so he thinks that like six to seven is like a juvenile Bigfoot.

Ellen: The reckless teenager.

Elliot: Yes, exactly. These are like reckless teenagers that don't know any better than to hide from humans.

Ellen: Implying that like the hiding is a behavioral thing that they have to learn.

Elliot: Yeah. Yeah. Which I mean smart on them because humans have caused a lot of ecological destruction. And if you're trying to survive as a species, if you have the brains to it's best to avoid.

Ellen: Hiding from humans is a excellent strategy. I must say.

Elliot: You know, at the same time, like how well can something that is like seven to 10 feet tall, really hide? And it's not like these are terribly unpopulated areas. The west coast of the United States is not unpopulated by any stretch of the imagination. So again, thinking about whether or not we can say that it's [00:27:00] plausible, that this kind of thing is wandering around the woods. Not super likely. The other thing about Bigfoot is that if we're assuming that Bigfoot is related to humans and primates, generally. By and large, great apes, which are part of the primate phylogenetic tree. The family tree of primates, great apes are the largest ones they don't have tails is one of the really big differentiators between great apes and the other like monkeys. Great apes includes gorillas, chimpanzees and Bonobos, and technically humans. Although obviously we're sort of our own thing. So Bigfoot taxonomically would make sense within the great apes. So what we know about great apes is that we're very social creatures. Obviously humans are very social creatures. We live in large groups, chimpanzees, Bonobos, gorillas, they all live in these huge groups.

Elliot: So if Bigfoot is a great ape, you would expect it to be in these huge groups. The exception to that is the last great ape is the orangutan, which is pretty different from the other great apes, because while the other great apes are very social and they live in these huge groups, orangutans are much more solitary, but usually live with like a mom and some kids in these like huge home ranges that like overlap a little bit with other orangutans, but not, they try not to, uh, come together very often. So. Maybe we're talking about a species that does have something a little bit more orangutan- like, we have these smaller groups, which would make it a little bit more plausible that they could be, you know, if we have one Bigfoot and their babies [00:28:30] and they have like a 50 mile home range, because this is like a huge, bigger than an orangutan so we would give it a bigger home range. Maybe there's just such a low population density that we haven't seen them. So that's where, you know, I'm pushing the plausibility up a little bit because you would think if it is going to be a solitary great ape, the only like reference we have for that is the orangutan. And they do have very, very large home ranges that barely overlap. So, maybe the population density is just very, very low.

Elliot: So, you know, I'm going to give them like one or two points, in plausibility there. Taking down a whole notch for the fact that this is a seven foot tall primate wandering through the woods, giving them a little bit back and then also giving them back because like you said, that idea that like the hiding is like behavioral because I live on the west coast and Bigfoot merch is everywhere. And you see a lot of stickers that like roadside stands that say Bigfoot hide and seek champion. It's sort of implying that like Bigfoot are avoiding people on purpose. And really there's no way to believe in like an actual, tangible Bigfoot and think that they're not actively avoiding humans because if they were not actively avoiding humans, we would have found them already.

Ellen: This has gotta be intentional.

Elliot: So it's sort of built into, like, if you read that website that I mentioned the, uh, the Bigfoot Field Research Organization, like in their like behavior section, they talk about avoidance of humans and they also talk about things like Bigfoot will like, throw rocks at people to like, get them to run away. Like that's something you see in a lot of big foot stories is like rock throwing, log throwing, [00:30:00] smashing people over the head with rocks, which certainly rocks sort of sometimes if you're in a mountainous area, do roll loose and roll down the mountain. Um, but if we're talking about a big primate, that's trying to get people to stay away.

Ellen: Some hostility.

Elliot: Yeah. You know, especially if we're talking about like, like with orangutans, we're talking about a solitary mother and like maybe one or two babies. We know how like bears act when you get near their baby. So maybe these are mother Bigfoots trying to keep humans away from their babies. Maybe that's why they're being so aggressive with the throwing of rocks. Which again, you hear that a lot, is this idea that Bigfoot is like throwing rocks at people, smashing them over the head with rocks. I don't know that I've ever heard of a specific account of somebody being smashed over the head by a rock by Bigfoot. But it is something that comes up in like Bigfoot lore a lot.

Ellen: I'm also imagining like a territorial male, right? Like if it's like a male that is feeling territorial and sees a human in its range, a human might be something that it would maybe recognize as like a potential competitor and then act hostily towards that.

Elliot: Yeah, that's true because I mean, if we're looking at Bigfoot and recognizing sort of ourselves and our species in Bigfoot, presumably Bigfoot has enough intelligence to recognize us as something similar to that and therefore, please stay out of my territory.

Ellen: Right. I wonder if humans would activate that uncanny valley, like uneasiness in Bigfoot to be like "uhhhh something's off here".

Elliot: Bigfoot sort of brings that out and us is this like," whoa, it's like us, but it's not like us. And I don't know how to feel about it."

Ellen: Just off enough. The vibes are just like [00:31:30] slightly...

Elliot: Bigfoot apparently has this absolutely terrible odor, that you're supposed to be able to smell a mile away. It's like the Bigfoot field researchers Organization has a stat of 10 to 15% of closing counters include this intense disagreeable stench, to which they would say that's proof, to which I would say there's a lot of things that smell very bad in the woods. Decomposing animals for one, not a great smell, skunks, not a great smell animals poop in the woods, not a great smell. So, you know, I'm not going to give Bigfoot a lot of plausibility points back for that. Another thing is like one of the classic Bigfoot things, and this is something that you see in those Coast Salish stories, like the native people have these stories of like big whistling, this idea of whistling and other noises that are associated with Bigfoot like howls, roars, knocking sounds like a repetitive knocking on trees, which other than the whistling, you can pretty much describe away the howling and the roaring with other animals in the woods that and roar like mountain lions, like scream. They make like a, like, I think that they're called mountain screamers in like some parts of the country. These are animals that scream, um, and they also live all across North America. You know, you can sort of explain a lot of the howling and the roaring and like the repetitive knocking sounds easily explained away by wind knocking, like a loose branch over and over and over again.

Elliot: Whistling, I don't really know how you would explain away. I personally can't think of any species that I know of in like the Western United States that whistle, [00:33:00] although birds can make sounds that are like, sort of whistle-y. So maybe that's, but you know, we will get to a point a plausibility point back for, I don't know, what's whistling out there? Could be a, could be a Squatch, could be. I don't have a great explanation for whistling. I'm sure that somebody that is much more familiar with the ecology of birds in the Western United States would be like, oh, I know exactly a bird call that sounds like a whistle.

Elliot: I'm also

Ellen: thinking, because you mentioned that they would have a very low population density and a very wide home range yet they still do have to meet somehow. Like they got to find each other somehow. So they would need some way to communicate over a large distance and whistling could get the job done.

Elliot: It's true. Yeah, it is. It's a sound that carries for. So maybe this is a really great adaptation that they have this whistling communication.

Ellen: Yeah. And something that like wouldn't necessarily give away exactly what they are, either. Like a whistle could be something that would carry and also not particularly scream "hey, there's Bigfoot over here."

Elliot: Yeah. They're not like shouting out into the woods. "Hello! I'm a Squatch!" And letting everybody know. So that's sort of, I guess my plausibility, to just summarize, is taking a bunch of points away for this is a very large animal that we have somehow not seen. You get a little bit more points back for, it's possible that they are one behaviorly actively avoiding detection. And two, if we're using orangutans as like a proxy, they could have these very massive home ranges, very, very low population densities, which could lend credence to the idea that there is something out there. So giving them some [00:34:30] four out of 10, giving them a couple of points back, giving them the benefit of the doubt, because again, I want so badly for Bigfoot to be real. I want it so bad.

Ellen: Absolutely. The other category we wanted to rate Bigfoot on, instead of our usual ingenuity is mystery. How big is the gap in our knowledge? What questions are there that are like, well, we don't particularly know, like this could be a Bigfoot thing. Like what would you rate Bigfoot for mystery?

Elliot: I think that I would rank Bigfoot, maybe like a seven or an eight in terms of mystery, because there are a lot of things that I think about Bigfoot that for one, like I said, in possibility, like there is the potential for there to be something that we haven't seen. But I also think that if we go back to thinking about the okapi, right? It's this idea that the indigenous people of that area knew what was going on and, you know, white people just didn't want to believe it. And I think that if we're talking about Sasquatch, specifically thinking about like the origins of Sasquatch and in the sort of Pacific Northwest area, the Western like mountain ranges of the United States and Canada, we see that like our definitions of what species exist, isn't really compatible at all with the way that indigenous people think about like these species. Uh, Wayne Suttles again, when he was like doing this research about like, well, what do the Salish people say about Bigfoot? [00:36:00] He, he really finds that like, there is no distinction in like bare, like thought of the real and the mythical, like that aligned, that doesn't exist. And they would tell you very frankly, his informants are like, "yeah, big food is a real animal, just like a whale or like a bear. This is a species that exists." Like they would give it in their list of their, listing all the species that live in their area. That's something that would come up. And I think that part of that, and part of the way that like Wayne Suttles talks about it is that Western science doesn't really have the capability to cope with that. We don't know how to deal with that. And he talks about like some anthropologists. He knows for a fact that those cultures have like Bigfoot stories or Sasquatch stories, but then you read the anthropologist account and it's just totally left out. And he was like, I don't think that this is like intentionally trying to like hide that information. I think it's just that an informant told them that and they went, I don't know what to do with that information. I'm just not, I don't know what to do with that. There is a lot to be said about our capability within like Western thought in Western science to not be able to deal with the existence of something like Bigfoot.

Elliot: And I think that that inability of us to wrap our head around the fact that like real and mythical and supernatural and natural are categories that might not exist, it's just totally outside of our worldview. So I think that that inability of our own Western thought lends a lot to that mystery. So maybe there is no tangible physical Bigfoot, but [00:37:30] you see in these societies where Bigfoot exists, like the Coast Salish, that they are doing things in reaction to Bigfoot, they, they know that Bigfoot exists and they were avoiding certain areas because of Bigfoot and they have stories about Bigfoot and they live in a world where Bigfoot is real, just like all the other like creatures that we might call mythical. They live in a world where Bigfoot is real. And in that sense, Bigfoot is real, because they're reacting to it. And this is the case in pretty much everywhere, where there is some sort of story of Bigfoot or some other kind of species that we would call mythical. Like the people are reacting to it and know that it is real.

Ellen: He's practically real.

Elliot: Yeah. It's functionally real. And that society, whether or not I can go touch a Bigfoot, the, the potential that like, we just, as like people from our social position, can't really grasp the idea that these things can all like coexist, I think that that lends more to the mystery of it. You know, maybe it's just sort of outside of our own framework.

Ellen: His impact is real.

Elliot: His impact is real. And I mean, like outside of like the whole philosophical thing that I just went off on with like indigenous cultures, which is really like what my like, research is in is thinking about like taking indigenous cultures and their oral histories at face value is really important to the research that I do. But like moving away from that, if we're talking about like Bigfoot's impact to us, Bigfoot holds up economies in some places. That is, you know, like there are towns that's entire tourists ecosystem is built around Bigfoot. Bigfoot is real to those towns because their entire economy is based on Bigfoot. I [00:39:00] have this like dream of, if you drive up highway 101, which is sort of goes along the west coast, if you drive 101 up from like Marin county. You pass so many Bigfoot like tourist traps. And I have a dream of one day stopping at every single one. Normally I'm going somewhere on purpose and I don't have time to do that, but like Bigfoot has a function in that, like those places, you know.

Ellen: It's a big foot pub crawl.

Elliot: Exactly! Ah, the dream, a Bigfoot pub crawl. Really what I want to do is I have this like life goal to do a cryptid road trip across the United States. Um, you know, go see like all the best, Bigfoot museums, go see Point Pleasant, West Virginia, where Mothman was cited, go to like there's places that have like jackalope museums. And end it at there's like a cryptozoology museum in Maine. And I like, you know, I want to do this whole big road trip. But that's like examples of these things, like all across the United States where like, there were like whole towns that it's like, we need to believe that this exists so that we can build our entire town around it. We need other people to believe this exists so that we can build our town, our whole entire town's economy around it, you know? And again, so like in that sense, Bigfoot is like real he's like he has an impact in the world.

Ellen: Yeah. Very, very tangible footprints as it were.

Elliot: Exactly. Yes. The tracks of Bigfoot are just littered across the United States.

Ellen: Massive, massive Bigfoot prints.

Elliot: So again, not to get too philosophical or metaphysical on this podcast that is about animals and nature. But I do [00:40:30] think that something that like anthropologists study and something that I studied specifically in archeology is the idea of like the relationship between people in the environment and the way that people conceive of the environment and how that impacts how you like live within the environment. And I think that again, Bigfoot maybe ties into my research more than I realized, because what Bigfoot is, is like a manifestation of the relationship between people in the environment. And also, and this is probably way too, like out of left field for this podcast. But if you think about it, the way that like people relate to the environment is really reflected in Bigfoot because in like Coast Salish society, Bigfoot is like an animal that is similar to humans, but not like humans that you have to interact with.

Elliot: And there's much more of like a symbiotic, like leveled out relationship, whereas in Western society, which is capitalist and like we're all built around market economies and like commercial value. Bigfoot is being used as a commercial, like tool. Like Bigfoot's part of the economy is functions in the economy as something that you can make money from.

Ellen: Like a gimmick.

Elliot: Yeah. Like I think that speaks something to the way that like we function with the environment and the relationship we have with our environment. So really in that sense, Bigfoot encapsulates our relationship with the environment.

Ellen: It's an interesting indicator of your sort of cultural values.

Elliot: Yeah. I love Bigfoot. Bigfoot is a great tool for like thinking through things, I think, you know? It tells you a lot about society and yourself. I mean, that's what we've been talking about this whole time. It tells people about, where do we fit in society? What [00:42:00] is it like to be the only member of our genus that's still alive?

Elliot: Bigfoot really, he's what we make of him, you know? And I think that that's really important for telling ourselves stories about us, which is, again, humans are obsessed with.

Ellen: He's a great prompt.

Elliot: He is, he's a think piece.

Ellen: He is, he's a jumping board.

Elliot: Okay. Yeah. And we live in a think piece economy right now.

Elliot: You know, people want to write like a good good think piece. So I think, you know, Bigfoot really slotting right in there. Yeah. Like a jumping board, really. And again, talking about this idea of like taking indigenous oral history at face value, first of all, calling it oral history. Like these are histories.

Elliot: And also like, like my research, I like study how the Coquille tribe in Oregon manages their like, um, environment and specifically like how they maintain sustainable, like shellfish harvesting practices. And it's like, based in like their worldview wherein shellfish are people. And if there are people and they're relatives, you have to maintain a reciprocal kin relationship with them. So you can't like take advantage of your relatives and like totally destroyed an ecosystem. Totally disrespectful. Totally not how you handle relatives. And you see that they are maintaining a very like symbiotic relationship with them, which is like, based in this idea that these are relatives. You know, if we're trying to tie this into, like, this is an animal podcast, we're talking about animals, the idea that like humans are something totally different from nature is sort of something that we made up.

Elliot: And a lot of indigenous cultures are like, it's not even that like, oh, we are animals. [00:43:30] It's like the opposite, animals are people. And we're seeing in terms of conservation worldwide, like, so much knowledge from indigenous peoples turns out was like the thing that was keeping those ecosystems of float, where like, when you try to like take people out of those ecosystems, everything falls apart. Like I, again, I live in California, so our wildfires are like hugely created by the fact that we don't do indigenous cultural burning anymore. We had this idea, "fire is bad". We don't want any fire. Like we're going to suppress all the fire in all the like national and state parks. And then it turns out that no, actually you do need to like have controlled burns constantly because it prevents the buildup of like underbrush and like fuel. But indigenous people knew that. They'd been doing that for like 10,000 years. So in terms of trying to like fight things like climate change and like natural disasters, listening to what they have to say. And a lot of that information is drawn from their oral histories. Indigenous oral history comes into those sorts of things and like a really, really real powerful way.

Elliot: I mean, you look like 20 years ago and like what we thought we knew about like science and nature is like totally changed, you know? If you will like come to anything, like if you come to Bigfoot totally, like, "I will never believe in it", it's almost naive if you think about it, because if you look at the course of human knowledge, we're constantly learning new things. And I think that assuming outright that we know everything right now, like we know everything that can be known is it's like a logical fallacy. Evidence says, if we can know anything, it's that we don't know everything yet. You know, like that's like the one thing we can know for sure is that we don't know [00:45:00] everything yet. We're constantly learning, constantly refining our knowledge in basically every single realm of science, but there's constantly new things to be learned.

Elliot: And so looking at something like Bigfoot and just assuming outright that can't possibly exist, we're never going to know it, you know, like sure. Maybe there isn't a tangible Bigfoot. But assuming that there can't possibly be is sort of, I think anti-, like, discovery, you know, it's like leave yourself open for like the possibility of more out there, you know, it's even if you don't ever actually expect to find a tangible Bigfoot, having that like curiosity and that like feeling of curiosity, and also people would go out into the woods and like go like hiking because they're like interested in that kind of stuff, you know? And that there are definitely like the tinfoil hat people that like, are like trespassing through areas that are not supposed to be, and like doing all sorts of stuff. But then, like, for example, there's a county in Washington that like listed Bigfoot as a protected species that can be, if you harm a Sasquatch, there's like a thousand dollar fine. Part of the reason they did that is because of, they are in an area where there's a lot of park land and people are like coming to visit to like be in nature. And so they sort of, they use Bigfoot as this way of promoting, going out into nature and like being a part of the ecosystem and being respectful of it. So they use Bigfoot as an opportunity to do that stuff. And I think that, like we sort of said Bigfoot, like a springboard for other [00:46:30] things, Bigfoot like pushes you towards like curiosity and interest in nature and gives you that wonder, you know, even if you don't ever expect to find Bigfoot in real life, it's so fun to think about it. And I think that that like joy and like playfulness of Bigfoot can really lend itself to keeping people interested in things like science and nature and what it means to be human and what it means to be human in relation to the environment, because life would be really, really boring if we knew everything already, you know, and life would be really boring if we just thought, well, there's nothing more to learn. Yeah, let yourself have fun. Believe in Bigfoot, believe in aliens. Believe in ghosts. You know, there's nothing wrong with wanting there to be something out there. That's more than we know right now.

Ellen: Oh, hot take for this podcast I know, but I a hundred percent with all of my heart, not even the faintest, hint of irony, believe that there are aliens out there somewhere.

Elliot: Well, there are 100% aliens out there because the universe is infinite. And to think that humans are that this is the only time that life has ever happened ever, any kind of life is totally self obsessed of us like--

Ellen: Ludicrously, narcissistic.

Elliot: So narcissistic and humans love to be narcissistic, but it's like the idea that there's like literally no other kind of life out there is just ridiculous. It's an infinite universe.

Ellen: It's a numbers game at this point.

Elliot: The likelihood of them and us running into each other is heartbreakingly low, very, very low. But the same thing could be said for aliens is that it encourages people to be interested in space and interested in space [00:48:00] exploration and like. Sure. Maybe you don't ever think that aliens are, they're going to find an alien, but it encourages that like fascination in space. So I think that Bigfoot can be very inspiring in that way. You usually wrap up your episodes talking about the conservation status of these species. So I already mentioned that there's the, Skamania County, Washington protected species officially on the county law.

Ellen: I love that. I love Bigfoot having legal protections.

Elliot: Oh, yeah. And I don't know that they've ever had to give a thousand dollar fine or a year in jail for harming a Bigfoot, but you know, it's on the books.

Ellen: That would be a big story.

Elliot: In 2018, so tragically, there were two bills that didn't make it through the Washington state legislature, but there were two bills on the floor. One of which was going to make Bigfoot Washington's official state cryptid like, you know how you have an official flower or an official bird. They really wanted to like to make Bigfoot the official state cryptid, which would obviously sort of go along with like certain protective status for it. But then also there was another bill to create specialty license plates that would have Bigfoot on it.

Ellen: That'd be so cool!

Elliot: The idea being that if you bought that specialty license plate, the money would go to the Washington state parks, which tragically didn't happen. I was living in Washington at the time and I was like, yes, yes, yes. And then it didn't didn't pass the legislature.

Ellen: Did it not pass in the sense that they don't have a state cryptid or--

Elliot: Yeah we don't have a state-- nothing is the state cryptid.

Ellen: I was gonna say like what could possibly beat Bigfoot?!

Elliot: What could possibly beat Bigfoot in Washington? That's [00:49:30] basically what they have. So, no, it didn't. Nothing passed. Um, and they do have like a specialty license plate program where there are like animals and you can buy like a Orca, you know, license plate and it, the money goes to the state parks.

Ellen: We've got that on our car. We've got the bear one.

Elliot: Yeah. But of course the state legislature decided to have absolutely no fun with it. And didn't pass the Bigfoot one, which would have benefited state parks, which is another thing that I think, you talk a lot about on the show of the idea of these charismatic big, like animals, like the Panda bear or like, you know, the gorilla, like these really big charismatic species that sort of end up being like ambassadors and like spokespeople for their entire like ecosystem.

Elliot: And like ultimately it benefits the entire ecosystem to try to be conserving that one species, and Bigfoot certainly can like serve that sort of function in terms of like conservation, like in 2017, the us forestry service for their April fool's joke did like a huge thing about the loss of Bigfoot habitat and "the habitat of one of America's greatest legends may be at risk" and they have these like posters and stuff made for April fools.

Elliot: And then at the end of this long thing that they had about Bigfoots, like habitat being like endangered and stuff, they ended it with real stats on like forest loss in the United States. Bigfoot can be that, that charismatic, like large species.

Ellen: That's your flagship right there.

Elliot: Exactly. You know, like Bigfoot has a lot to give in terms of [00:51:00] conservation and learning to like care about these spaces. And I think he's more than happy to be the face of that. Uh, those kinds of movements.

Ellen: What is your, what are your thoughts and feelings towards fake Bigfoot videos and photos and stuff? Like we've all probably got an image in our mind. Okay. The film it's the Patterson Gimlet Bigfoot film. That's the thing that everybody's like familiar.

Elliot: You're like close your eyes, picture it. You can see Bigfoot walking. His arms are swaying and he likes sort of looks to the camera. That's the Patterson Gimlin film that is fake. And I think what I would say to them, no flair, no fun. You know, it's one thing for somebody to like, say that they saw Bigfoot. It's another thing to like trick people into saying you saw Bigfoot or like, you know, it's one thing to like, have your entire towns, like tourist economy based around like being Bigfoot country. And another thing to just lie to people, to get them to come like, hey, Bigfoot is out there and he's special and you're taking away from that.

Ellen: And now he's being misrepresented basically. And it's also a sense of like, well, how do you know that? That's what Bigfoot would even look like? Cause then they're placing themselves in a position of authority being like, this is how we're going to say Bigfoot canonically looks like what gives you the right to say what Bigfoot looks like.

Elliot: It's tragic. There's this really interesting study that somebody did, where they, they modeled the, what the range of Bigfoot habitat would look like based on Bigfoot sightings. Like they took Bigfoot sightings [00:52:30] and overlayed them over environmental data, and then like extracted what categories lend themselves most to Bigfoot sightings. And basically moral of the story is they found that, um, the Bigfoot habitat range and black bear is exactly the same. Interesting, interesting, interesting thing about Bigfoot ranges is it is statistically exactly the same as the American black bears range do with that information what you will, saving Bigfoot habitat, saves black bear habitat. That's just a fact, they are exactly the same whether or not you're saying that those Bigfoot sightings were black bears. I don't know, but I can't say that they are exactly the same range. So if you protect Bigfoot the habitat, you are protecting black bear habitat.

Ellen: I will say an element of that that could be in favor of the tangible existence of said Bigfoot, is that that range clearly is going to be an environment that can already support a very large omnivore. That's an ecosystem that lends itself to the trophic level that we need to --

Elliot: Then we have another issue with plausibility. Is that like, can it support two different species that fill the exact same ecological niche?

Ellen: Yeah, I guess they would, wouldn't they.

Elliot: I don't know. They're in direct competition. Maybe the black bear have made Bigfoot go extinct. Maybe they out competed them in their natural range.

Ellen: That would be in direct opposition to the [00:54:00] arguments of pretty much every dude who has said they could beat up a bear.

Elliot: Yeah, no, they outcompeted Bigfoot. So what are you going to do about it? Who was saying they can beat up a bear?!

Ellen: I've seen dudes say they could beat up a bear. I know.

Elliot: Talk about human narcissism. Thinking that you can beat up a black bear. You're not going to win.

Ellen: They're not even the biggest bear.

Elliot: No, they're not even the biggest bear and you're still not gonna win. And also they don't want to fight you. Bears are not aggressive.

Ellen: I've never experienced an aggressive bear.

Elliot: I've been within like 50 feet of a black bear before they, and they just, it just sat there and stared at me and at the like huge group of people that gathered around to stare at it, which was very stupid of them.

Ellen: I mean, that's the thing, like maybe the bears and Bigfoot have sort of an understanding not to bother each other. Like, you know, maybe they're scared of each other.

Elliot: Maybe they recognize like, "hey. We're in this together, trying to avoid humans getting in our stuff."

Ellen: Game recognizes game.

Elliot: "Like I don't have opposable thumbs, so maybe if you could throw a rock at the human, that'd be great because I can't pick up a rock."

Ellen: They're teaming up.

Elliot: Yeah. This is an alliance. Definitely. Somebody needs to write a, like paper about like the species interaction going on there. It's a couple with the species modeling paper that demonstrated that their habitats are identical.

Elliot: See this is what

Ellen: I like about Bigfoot is that it gives you an opportunity to think about things like, well, how would, you know, an interaction play out between a great ape and a black bear living in the same place? Like you could probably look at like the interactions between bears and apes that live [00:55:30] in Asia, like in places where--

Elliot: Yeah, I guess that is, that's probably the only place that they really overlap, huh?

Ellen: Like there being like forests where you'll find probably like--

Elliot: Like a sun bear and an orangutan or something.

Ellen: Right bears and great apes live together in places like that.

Elliot: I mean, we share a range with lots of bears.

Ellen: So it's not unprecedented.

Elliot: It's not a great species interaction. Maybe we should learn from Bigfoot and their coexistence with the bears. We could all be a little bit more like Bigfoot, I think.

Ellen: And that's the tagline right there. That's the TLDR; we could all afford to be a little bit more Bigfoot like, and open your mind and your heart to Bigfoot. And it'll just unlock the entire world of childlike wonder.

Elliot: Yeah. And that's the thing is like, when people ask me, like, okay, but do you believe in Bigfoot? Like I said, I gave it a four out of 10 plausibility, but here's the thing: it's so much more fun to believe in Bigfoot. It's just so much more fun to believe in Bigfoot.

Ellen: Choose joy!

Elliot: Choose joy. Choose Bigfoot. Don't give up on your childlike wonder.

Ellen: It's believing with your heart and not your mind.

Elliot: Exactly. Well, like I said, I did give it a four out of 10. There's the sliver of hope because I can't give up on the fact that Bigfoot's out there waiting for me to hang out with them.

Ellen: It's what he represents, what he stands for.

Elliot: It's what he represents to us in our hearts, and our souls.

Ellen: He's an icon.

Elliot: He's an icon. He's our dear relative. He's the only other extant species of our genus. I'm going to say it now.[00:57:00]

Ellen: He would never give up on us. So believe in Bigfoot, because he believes in you.

Elliot: Exactly. Exactly. I do think that I've seen like that like on a t shirt.

Ellen: That's probably on there. That's probably where I got it from.

Elliot: Yeah. Just, I believe in you Bigfoot and you believe in me.

Ellen: Bigfoot. If you're listening...

Elliot: Listening, somebody leave a like iPod out in the woods, for Bigfoot, blast it on some speakers out in the forest, let Bigfoot know that we're here and that we love him.

Ellen: I have to tell you, there is somebody out there who plays this podcast on speakers to keep cougars away. This podcast has been used as cougar deterrent, which I was overjoyed to hear about.

Elliot: Yeah, that's great. Normally like when I've had to do survey in areas where there are bears and cougars, I just occasionally like shout, just walk around you, just absentmindedly shout every once in awhile, just to let them know. I think it would probably be much more pleasant to the other people I'm surveying with to be blasting a podcast.

Ellen: As long as it's a podcast everybody can agree on.

Elliot: Who can disagree with listening to people talk about animals. If you're, if you're surveying in the woods and you have a job that involves you needing to survey in the woods. I think that you're the kind of person that wants to listen to a podcast about animals.

Ellen: We clearly all have common ground here. Yeah. All right. Elliot, before we wrap up for today, I would love it. If you could let our listeners know, like what kind of projects do you have ongoing right [00:58:30] now? What are you involved with that you want people to know about? Like, what do you want to leave our listeners with today?

Elliot: So I have two things that I want to shout out. One is a really big thing that I'm involved in is this anarchic archeology collective called the Black Trowel Collective. And we do a lot of things, but one of the big things that we do is we have a micro grants committee where archeology students that are in need of a little bit of financial help can apply to get like no strings attached money. Um, which is really great. So if you just Google Black Trowel Collective.

Ellen: How do you spell that?

Elliot: The trowel part T R O W E L. It's like a garden trowel.

Ellen: Got it.

Elliot: Yes. And then the other thing that I want to shout out is, so, you know, Sasquatch is inspired by Coast Salish, oral histories. So I want to encourage your listeners to support a land focused organization that is based in Coast Salish territory. There are a couple, but I'm going to shout out the Na'ah Illahee Fund specifically. They're based in Seattle and they have grants and a lot of community programs that support indigenous ecology, food sovereignty, and wise action, and they work to advance climate and gender justice. So I think that that's something that animal lovers and lovers of the environment can get behind is, you know, supporting indigenous ecology and food sovereignty in the Coast Salish homelands where Bigfoot lives and where the Sasquatch like stories come from. So I just wanted to shout out the, uh, Na'ah Illahee Fund and I can give you the link for that also.

Ellen: Awesome. Those links will all be in the episode description. [01:00:00] Yeah. So just scroll down on your app and you can click through this.

Elliot: Um, and you can find me on Twitter at archhelmer, A R C H H E L M E R on Twitter. I don't normally tweet about Bigfoot. I mostly tweet about some of the other stuff we talked about. The like indigenous oral history stuff, and broadly about the environment and other anthropology topics and shellfish. A lot of shellfish I talk about. So if you're into Marine ecosystems, I definitely tweet a lot about that.

Ellen: Which if you're here listening, you probably are.

Elliot: Yes. Yeah. I was so disappointed when, when I first started listening to this podcast, I was like, maybe I should email and I can do like a barnacle episode. And then there was a barnacle episode already, and I was like dang it!

Ellen: Sorry!

Elliot: That was like, well, what do I know as much about, as I know about barnacles? Bigfoot.

Ellen: And we had not had a Bigfoot episode. So now you are the, uh, the intro to cryptids on Just the Zoo of Us. Now, the precedent has been set. There is now an expectation.

Elliot: Oh boy, whoever has to talk about cryptids next, please. You do not feel like you have to talk about philosophy and anthropology as much as I did.

Ellen: That's the fun part of cryptids! It gets the wheels turning.

Elliot: It really does. And you know, Bigfoot is an anthropological topic.

Ellen: Yeah, absolutely. He fits right in with primatology. Yeah. We've had primatologists come on to talk about other primates.

Elliot: We have primatologists in my department, so, you know, it's, it's part of anthropology. It's very real.

Ellen: [01:01:30] Absolutely. Well, thank you so much, Elliot for spreading appreciation for Bigfoot, sharing your knowledge, and this has been delightful. Everybody go follow Elliot, scroll down, check out some of the links that they dropped. And thank you so much. We'll talk to you later.

Elliot: All right. I had a great time.

Ellen: Thanks, me too. Bye bye. Thank you so much for listening friends. I hope that you have learned something new, whether it's about Bigfoot or about yourself and your place in our big, beautiful world. Remember it is Bigfoot's world. We're just living in it. It has been refreshing to explore mysteries like cryptids and the unknowns of nature. With each episode of this podcast, I learned something new and come away with some new perspective. And I hope that you do too. It's really a theme that is central to this podcast and being able to explore those themes has been so meaningful, not just to me personally, but I just think it's an important thing to be doing always, but especially now when it's so needed. So if you too find exploring the mysteries of nature to be of value in the world today, and you are in such a position that allows it, please do sign up for a membership to support this podcast so that we can keep putting unabashedly joyful content out for all you nature nerds out there. One more time, that is maximumfun.org/join. [01:03:00] Next week, you, the audience, are the star of the show. Christian and I will be answering your questions. If you haven't sent them in yet, there is still a little bit of time. Send them to me via email at ellen@justthezooofus.com by Friday, April 29th.

Ellen: We are also going to be opening up those experiences that you beautiful folks have shared with us. So stay tuned for those. I really can't wait. I love y'all. Finally, thank you to Louie Zong for our beautiful theme music, and we'll see y'all next week for our Q&A episode Byeeeee.

140: Pangolins w/ Jack Baker!

Ellen: [00:00:00] Hey there friends and welcome to episode 140 of Just The Zoo Of Us! This week, I am joined by a conservationist and podcaster who is here to wallow in the delightful glory of the humble pangolin. We discuss how the pangolin's unique adaptations tip the scales in favor of this walking pine cone and what challenges they face in the world today. So curl up into a nice, cozy little ball and enjoy Just The Zoo Of Us presents: pangolins with Jack Baker!

[intro music]

Hey everybody, it's Ellen Weatherford. This is Just The Zoo Of Us, your favorite animal review podcast. And this week I'm joined by a friend who may not be a new friend to some of you. I'm sure there's quite a bit of overlap between our friends.

This is Jack Baker! Say hi, Jack.

Jack: Hello everyone!

Ellen: Jack is here to talk about -- okay, I'm gonna say it -- one of my all time, favorite animals, not a joke. It's almost like I've been saving it because I just like really wanted to make sure this animal was getting done justice. And like, I almost didn't want to take it on myself because I was like, it's so sacred to me.

This is the pangolin. Which is perfect for you because the pangolin is the namesake of your podcast.

Jack: Yes. Yes, it is. Not to add any pressure then to me at all, at all, I'm sat here, like face is going red, like, oh no, no. So yes, I am Jack. To anyone who doesn't know me, um, hello, and to anyone who does [00:01:30] know me, hello. And I'm the host of Pangolin: The Conservation Podcast, which started out as a podcast dedicated to all things pangolin. And then as it developed, I realized pangolins to me represent all of the kind of underappreciated, underdog, conservation stories out there. And so I kind of expanded from there and we've gone on to talk about all sorts of other bizarre, under appreciated, under acknowledged wonderful conservation stories, things like lemurs and red pandas and koalas and all the kind of bizarre little things that maybe you don't know a lot about to do with conservation.

So yes, it started with the pangolin and ended up here.

Ellen: Now we're here.

Jack: Yes.

Ellen: We have some mutual connections through the Lemur Conservation Network as well. We've had some of their folks on the show before, and I understand you have too, you've worked with them about doing some episodes about lemurs in Madagascar.

Jack: Yes. It was one of those things that I shot an email to them and just said, listen, I would love to have a singular representative of your show, kind of come on the podcast, talk about lemurs. Cause I think they're one of these things that people know a lot about. Maybe ring-tailed lemurs or know a lot about kind of the big kind of popular species

Ellen: Zoboomafoo is out there.

Jack: So they knew about these kinds of big things, but they don't know about all of the things that go alongside them. And so they came back to me and said, well, actually we have, we're a network. So we have so many different people that would love to speak to you. And I think we ended up with 12 episodes dedicated to Madagascar, and we looked to everything from lemurs to baobabs, to the communities that [00:03:00] live in Madagascar and the drought, and what's going on and kind of looked at conservation and Madagascar and lemurs from so many different angles kind of paint this full picture of conservation. And it was just fantastic. And like, yes, I love them so much. It's one of those things that I liked lemurs and I was interested in lemurs, but I didn't know that much about them. And now I'm like, they're up there. They're top tier always kind of just below, just below the pangolin, obviously, but still top, top tier.

Ellen: That spot is reserved. Locked in.

Jack: Yeah, locked in. It's, well, it's a toss up. People always ask me what my favorite animal is and assume because the podcast is named pangolin, it would be that. But tapirs are coming up the rear really close, really, really close.

Ellen: You're just a big fan of that sloping facial structure, aren't you? Is that what it is?

Jack: Maybe it is. Elephants as well, I'm a big fan of those. Yeah, it could just be --

Ellen: We love a good banana face, huh?

Jack: It's strange looking animals. Maybe that's what it is. I have quite a big nose. So if I, if I turn to the side, you can't tell on camera when we're looking at each other. But like, when I turn to the side, big nose maybe.

Ellen: Just a sense of like representation, like seeing yourself reflected in the animal.

Jack: Yeah. Yeah. And also I feel like the reason I chose to study the pangolin when I was kind of looking to create my podcast in the first place was because I kind of saw this animal that is small underrepresented, it doesn't speak up a lot, and I see a lot of, I was like, during the pandemic, it was kind of like that time where everyone was retreating inside, hiding away, not giving a lot of attention, not kind of speaking to and so I was like, we need to focus on an animal, which I see having those similar traits, the pangolin.

Ellen: [00:04:30] Curling up into our little balls.

Jack: Yes, exactly. Kind of hiding ourselves away and yeah. That kind of spiritual connection of like, oh yeah, absolutely. Trying to keep us on topic there, but I'm probably going to go off topic again immediately, but --

Ellen: Well, you'd be surprised at how on topic you were, because I was just about to ask you, like what got you into pangolins and more so just like, what got you into the work that you do with conservation?

Jack: Yeah. Yeah. So, well, pangolins came later, so I guess I'll start with conservation in general and then move forward. Animals conservation, are one of those things I think always have been in my heart, on my mind, always loved them, but in school and things, I was always one of those people who did well in written subjects like English or history or politics or that kind of thing.

Ellen: Yeah, me too, yeah. For sure.

Jack: So yeah. So naturally when you're good at something like that, everyone in your life goes, you should do that, go and do this and do it. So I went away to uni --

Ellen: You should commodify this!

Jack: Yes, you should commodify something that you're good at, even if you don't enjoy it! That's the way that the world goes. And so, yeah, I went away and studied kind of politics. And then while I was doing that, I was working in an aquarium to kind of earn money. And so this love of animals has always been there and kind of in the background. And I was always happiest around them and it got to the end of my degree in politics. And I went, when am I happiest? And my happiest when I'm sitting in class learning about politics, I could go and get a job in an office and do this, that, and the next thing, or I could go out there and put myself into conservation, follow this dream.

And it came down to, and I've told this story on my own podcast so many times, but I feel like it's a [00:06:00] great, and I'm going to shout him out again. The baby polar bear that was born at the Highland Wildlife Park in Scotland, little baby Hamish. So cute. A good Scottish name, a great Scottish name. So wee Hamish was born just after I finished my degree and I went up to the Highland Wildlife Park. I saw him and I was so happy, just surrounded by nature and seeing this incredible, beautiful animal be born. And it was that moment where I was like, I've not felt this happiness doing politics in so long. Like I'm going to jump and just commit. So I went back and did a master's in conservation and worked at Edinburgh Zoo and kind of committed fully to conservation.

And along the way there, I met the pangolin. So for my dissertation, we were invited to do kind of a creative thing instead of writing, maybe you could do something a bit different. So I decided to do a podcast series all about the pangolin, learned all about it, fell in love with it instantly. I think one of the first email communications I ever had with my supervisor at the time was she just sent me a video of kind of one of the pangolins they were tracking in Namibia and it was just rolling around in a mud bath.

And I was instantly in love. And ever since then, it's kind of been the one for me. That kind of, yeah. So, yes.

Ellen: I just said this on our babirusa episode, but I love a good wallow. Ah, man, you give me something that rolls around in the mud that's it, man. It's game over. I love that.

Jack: It is. And it's something that like, especially with the day we're recording, this is probably one of Scotland's four sunny days of the year. So I'm sat here, like, thinking about that video now. [00:07:30] I wish I could wallow. I wish I just had a nice cold, like chilled out space in the backyard where I could just go in like lie in water and mud, and just kind of lie there and bake slowly. Like, that's just the dream.

Ellen: What you do, you you go to a hardware store. You say you work at a botanical garden, grab some soil, go toss it in your backyard or on your driveway or something.

And then you just hose it down. And there you go. You got some mud going, baby. Yeah. You got yourself a wallow.

Jack: Yeah. I'm sure my family would not question that at all.

Ellen: " Is Jack okay?"

Jack: "He's just wallowing."

Ellen: Going through some stuff.

Jack: I love how usually when we talk about humans wallowing, they're like, oh, is he okay emotionally? Well, he looks happier than he's ever been, but he's physically actually wallowing in the back garden.

Ellen: It's an act of self care.

Jack: So yeah. In conclusion to wrap up that long-winded story: always loved animals. And, you know, it's one of those things that has always been there in my mind, conservation and animals, and growing up, watching things like Steve Irwin and Animal Planet and David Attenborough and all of these people kind of influencing. Now I'm where I am now, living the dream, I suppose.

Ellen: It's a familiar story, you know, I feel like a lot of people that come on here, you know, come from similar beginnings of being inspired as a kid. And, you know, I I'm glad that you said that you did work also in social science and political science too, because like, when you're talking about conservation, that's something that plays a huge role in it. You know, like you can understand the animals all you want, but you know, you got to also understand what's going on with the human element when you're talking [00:09:00] about conservation and how humans are affecting the populations of the animals. So, you know, that's all part of it together. I know you said that you kind of like departed from studying politics, but like. A great foundation to have when you understand the politics that are going on too.

Jack: Yeah, definitely. And it was what was great about my conservation degree that I did after my undergrad was that it was interdisciplinary. So it had people from political backgrounds, geography, backgrounds, biology backgrounds. And I think when you get all of those people in the same space, that's actually when you get the most productive results, because if you focus all on the science or you focus on the politics, you get very insular and you get these kind of set mindsets that just kind of develop.

And so having people around with these different backgrounds, I think was very constructive for me personally. It's one of those things where personally, I wish it wasn't political because I feel like there should just be this general consensus that we need to do good and right by the environment and plants and the animals that we love round about. But, it's never that easy. So it's good to have that skillset of like, okay, how do we, how do we deal with politicians or whatever it is that maybe have different agendas to the ones that us, me, you, the listeners have in our minds, in our hearts. So it's a good background, I think to, to have.

Ellen: You mentioned that during your master's program, you were focusing on pangolins. Did you have any opportunities to like travel, to see them or like work with them in person?

Jack: Oh, so you might've seen my eye twitch there because I was... my master's took place in [00:10:30] 2020, which was a interesting time. We had a research trip booked for me and several others to go to Namibia, to visit, learn from people there.

We were going to learn about the trophy hunting debates that go on around Namibia. It was all kinds of topics that were going on. And then March 2020 comes along and...

Ellen: That's rough timing.

Jack: Rough timing. I have never felt worse. I don't know if I've told this story on my podcast. So you're getting an exclusive for me on this one.

Ellen: This is premium content, folks.

Jack: Premium, premium content. I have never felt worse. I had a flat inspection that day from the letting agent that we were renting from. And I just got back from the gym and I looked at my emails and it just said like research trip has been canceled. So I was like, "it's fine. It's fine." So I went, had a shower, came back through, and then I started processing it and just at that moment, the letting agent knocks on the door, and then she comes, she said, "I'm here for the inspection." And she walks up the stairs of my flat and finds me sitting on my bedroom floor in a towel, just sobbing, like, "I can't go and see the pangolin." and she's like, okay, and then she very quickly does it. She quickly goes and does a little run around the flat and then out in seconds. So really I could have had a real mess in there and they would never have cared. They were in and out, but you know, it's uh, so it was a moment.

Ellen: "You seem to be experiencing something"

Jack: "we're just going to leave you to it. Um, and just say, yeah, yeah, it's, it's fine."

Ellen: You know what that would have been a great moment for? A good wallow.

Jack: It would have been the perfect time for a wallow. It was, it was the closest I've ever been to a [00:12:00] wallow, just, um, but yes, so never got to go and see them. But the good thing was in the age of technology, we were able to do kind of camera trapping exercises, where we spoke to people in Namibia, uh, and we were each kind of a assigned animals to track and get photos of and all sorts of things. So I feel like while I didn't get to see it, I got a really good experience. I think it also taught me that, like, we don't have to be jet-setting around the world to learn about animals all the time, which I think is an interesting concept. And it also sent me down this path of like, I got the job I'm in now because I was good at online communication skills that I learned through studying the pangolin and through communicating with people all over the world during the pandemic. So while I didn't get to go on this trip and didn't get to form that physical connection necessarily, it's kind of led me down this like really good domino effect of like, oh, I got a job because of it other good things going on in my life that have all happened because of the pangolin and because of one research trip being canceled. So yeah.

Ellen: It sounds like you mastered the long distance relationship.

Jack: I think so. I think there's, it's the most successful relationship I've ever think I've had in my life. Um, but yes, mastered nailed, it a hundred percent. Um, it gave me a good excuse, I suppose not being able to go and see them in person if you're in the country and you're trying to organize physical meetings with people to discuss topics and things, it can be quite difficult to pin people down, but recording a podcast, the great thing -- we were able to just like email people in Hong Kong. We could email people in Namibia. We could email people wherever in the world they were and kind of chat to them. And so I think in Scotland, we have this [00:13:30] saying, what's for you, won't go by you. Which basically means if something is meant to happen, it will happen.

And when that was first said to me, I was like, but I wanted to go though. Like, whereas now it's kind of like, okay, now I've taken a step back and had kind of other kind of retrospective look and it's good. And yeah. Mastered the long distance.

Ellen: So for listeners who might be hearing your joy and love and passion for the pangolin and are perhaps listening and thinking, what on Earth is a pangolin. I've never heard of this thing in my life. Possibly might be thinking you are saying penguin, which I've had-- I've had that struggle in the past

Jack: Every single automatic transcript. Cause it was submitted as part of a dissertation, I had to write transcripts for all of my podcasts and Microsoft word, all the transcript is great until it replaces everything. It thinks I've written a dissertation about penguins that live in Namibia, which is just not no, no, no, no. Not a thing.

Ellen: That would be way bigger if true.

Jack: Yeah. I was going to say I made a great discovery. If there were penguins living in the deserts of Namibia, that would be, I'd be world renowned by this point, if that was a thing,

Ellen: We're not talking about penguins today, but folks might be listening and might be like, "what is this creature? I've never heard of this in my life." I don't feel like, you're not going to find them in, you know, baby's first animals. In fact, I have a memory of being in a biology lecture and one of my professor's slides had a picture of a pangolin on it when he was talking. I think he was talking about [00:15:00] keratin, which we'll get into later. I'm sure it will come up and had a picture of a pangolin on there, but he didn't say anything about it. It was just a picture on the slide. And I heard these two girls sitting behind me kind of whisper to each other. "They're like, what is that?" like, I don't know what that is. And one of them was like, "I think it's an armadillo?" Cause we have armadillos here. So they kind of see some similarity with the nine banded armadillo. But they were like, "I think it's an armadillo, no it kind of looks like an anteater, what is this thing?" And like, I knew what it was. And so I got to turn around and be like I said, "guys, y'all need to Google pangolin P A N G O L I N." I was like, "Google them, look up every picture you can, learn everything there has to know about this creature. I don't have time cause we're in the middle of the lecture. So I cannot info dump on you right now. But Google it, you will thank me later," but like people don't usually know what pangolins are. So if someone comes up to you and asks you, "what's a pangolin," what is your intro to, elevator pitch for the pangolin.

Jack: Okay. So I, uh, it's a hard one because as you say, no one knows and I've had similar experience where people, like the first time I showed them a picture, they'd be like, so are you studying like a reptile?

Because it has like, it looks like a, like it's got scales. Like, is it a lizard or is it like a, and it has the tongue, it has a very long tongue. So again, it looks kind of reptilian and you're like, no. So the pangolin, for anyone who doesn't know, is the world's only scaly mammal. They range in size for a couple of kilograms all the way up to about 33 kilograms, depending on the species, there are eight different species found across the [00:16:30] world four in Africa four in Asia, and they are really hard to describe if you imagine an armadillo, but with a kind of a longer kind of bulkier tail. And instead of bands, scales, almost like, well, they're not even really reptile because they don't stick flat down and they kind of stick out. So they are, they're hard to describe. And a lot of the time it just results in me going "google a picture, just go and Google a picture." Come back to me and we can talk about them for hours, but trying to get that initial image in someone's head is really hard to conjure up. So yeah, it's a small scaly mousy armadillo -y mammal.

Ellen: I feel like they look kind of, to me like, uh, an anteater with scale mail, like plate armor that has like the overlapping, like metal scales on it. Like, you'd see on some sort of knight in a fantasy movie or something.

Jack: Yes. And something actually, I've been listening to recent episodes that you've been releasing and Pokemon keeps being brought up.

Ellen: Oh yeah. Without fail.

Jack: Yes. So I'm going to continue that trend and say, if you love Sandshrew and Sandslash, like I do.

Ellen: Absolutely.

Jack: They are the pangolin of the Pokemon world, the kind of beigey mousy kind of sandy looking creatures. They don't entirely look like Sandshrew or Sandslash, but if there was a middle evolution for them, that's probably where the pangolin would land in this kind of strange kind of intersection of the two.

Ellen: They got the claws, they got the big scale. They dig in the sand.

Jack: The funny nose.

Ellen: There you go, that's Sandslash all the way.

Jack: Yeah. So for the people who, we've not isolated with that kind of [00:18:00] comparison, that's the perfect one. That's the best way to describe.

Ellen: And that is to say like, not all of the pangolin ones are digging around on the ground. Right? You mentioned the ones that you studied were in Namibia and the deserts. So there's a pangolins that are kind of, they walk in a really funny way where they kind of walk around on their back legs with their front legs, kind of like tucked up under them in a very cute way. But there's also pangolins that live up in the trees. Those are just delightful too.,

Jack: I think they're so special because it's like the designing of the pangolin has been perfected and then they've just altered it slightly for different areas and different places where they need to be. So, yeah, I kind of know a little bit about the tree dwelling. Semi arboreal pangolins they kind of live on the ground and then disappear up trees, they can help support their whole body weight by their tail. Which I think is really interesting and exciting and cool. Normally, I kind of said that like, oh, I think that's cool. Like I'm not on a podcast where everyone is going "this is really cool." like--

Ellen: We're all in this together.

Jack: We're in, we're knee deep in this now.

Ellen: Target audience acquired.

Jack: So they all kind of burrow and they'll kind of disappear underground, but there are some that will disappear up trees as well. The black bellied and white bellied pangolin and the African species will whoop! up trees. Um, and yeah, they can hang on from their tail. So I know a little bit, maybe not an expert, but I feel like the design is fairly transferable. It's just like these little variations between them that set them apart.

Ellen: Much in the way that Pokemon vary by region.

Jack: Exactly.

Ellen: I promise --

Jack: We're not getting into Alolan--

Ellen: This is not a Pokemon fan [00:19:30] cast um, I mean it a little bit is.

Jack: The one that I was kind of looking at is the Temminck's ground pangolin. But I'm the type of person where once I am studying, once something, once that door is opened, I'm going through all the different pathways and trying to find that. So, yeah.

Ellen: We're just neck deep in Wikipedia, got 40 tabs open at which I mean, listen, we've all been there. I've been there. If somebody were to try to like locate the pangolin on the mammal family tree, where would you find the pangolin, like what are its cousins? I like to think of this so that I can kind of understand, like, what is the evolutionary context that animal is in, like, and you'd look at a pangolin, and it might be kind of tough to figure out, right? You're like, you know, it hangs from its tail, like a primate, but it digs in the ground like a mole, but it also eats insects, like an anteater, like there's so much going on. Like where would you find the pangolin in our big family tree?

Jack: So this is going to confuse the situation even more. It's so bizarre right there. So you'd think polusa the anteaters. It would kind of fall boom, right in there with giant anteaters, all sorts of things. But in fact, closest relatives are carnivora, cats, dogs...

Ellen: Out of left field!

Jack: I don't know why. I don't know why! It just is kind of this bizarre. Like it shouldn't fit there in my mind. It shouldn't because it's an insectivore, it has the kind of long tongue, like the anteater.

It has the kind of scales, almost like an armadillo-esque type creature [00:21:00] and it just, yeah. It shouldn't fit there, but there is a near carnivora with everything. All those other things.

Ellen: Reminds me a little bit of, we were just talking with Dr. Christine Wilkinson about hyenas, and they mentioned aardwolves, which are hyenas and yet eat bugs. So they can have some interesting builds.

Jack: I'm, I'm really intrigued by this bizarre convergent evolution than wherever --evolution to me is something that I wish I could take, like a step back into the universe and look down and just watch. And I know, I don't know if you're familiar with the video game Spore. Oh, I played that game so much as a child.

Ellen: Oh my God. So much.

Jack: And so I wish there was kind of a real life Spore of like," how, how can I fully understand it?" I mean, there is the science textbooks out there that would explain it all to you, but it needs to be presented in that kind of Spore like easy way for me to fully process it.

Ellen: Staring at the pangolin like, "why are you like this?" I mean, I'm glad you are.

Jack: Especially cause like the typical armadillos and eaters are all kind of south Central American species. And then these guys are found across China, Indonesia, and a lot of Africa. So Africa and Namibia, that kind of area. So it really is kind of this weird convergence of similar traits in a very kind of different way. And so yeah, I find that to be bizarre, confusing, but somehow makes me love them more. Cause I'm like, I don't know what you are, but I just... Good for you.

Ellen: I love when the animals that are not related to each other and live nowhere [00:22:30] close to each other, occupy a similar niche in their ecosystem, like maybe they're performing a similar role or they have a similar job in the place where they live. And so, you know, you start to see these sort of eerily similar features that get copied and pasted just because that's what works best because of that tool. Right?

Jack: Yeah. If it's the best way to do it, of course. It just makes sense.

Ellen: You're going to get there eventually.

Jack: Yeah. And I think what's special to me about pangolin is that it seems to have picked the best and most interesting traits from a kind of variety of different things. So like with the burrowing and the climbing and the, the way that it rolls up and all of these sorts of it's like taking all the most charismatic, interesting traits from other animals and smoosh them together and going, "this is me, this is what I'm going to be".

Ellen: Well, let's get into it. Let's dig into these awesome, cool traits. If this is your first time listening to our podcast, what we do is we rate animals out of 10 in the categories of effectiveness, ingenuity, and aesthetics, starting with effectiveness, which for us is physical adaptation. So things that are built into the animal's body, like things that they have that let them do a good job at the things they're trying to do. They're trying to not get eaten by other things, get their food and get their prey, things that are built into their body that let them do their stuff. What do you give pangolins out of 10 for effectiveness?

Jack: I don't know if this is controversial and I don't know how many previous guests have come in with the big guns and gone "I believe my animal is best", but--

Ellen: Pretty much all of them, but it's okay.

Jack: Okay. Well, I'm going 10. I'm going [00:24:00] 10.

Ellen: You absolutely have every right to do that. And I did show my hand earlier by saying that I love them so much. So like I'm clearly going to let it slide.

Jack: Um, cause I've knocked a couple points off here and there in the next round. So don't worry. People are thinking he's just going to be biased to give them ten for everything, I'm not. But for effectiveness, I think physically the pangolin is adapted perfectly to where it is, what it needs to do, what it eats, how it protects itself, how it kind of raises its young. I can't think of any way to fault this physical design.

Ellen: This is what peak performance looks like.

Jack: Exactly. This is the Venus and Serena Williams of the animal world. The kind of top level. There's no one above.

Ellen: The platonic ideal of an animal.

Jack: Exactly, exactly what you want an animal to be, which might sound strange because I think a lot of people would think elephants or like, whales or like these big popular animals, they must be peaked because they are the most popular. No, it's the weird ones that are best. I have written down some things that I think make it special. First of all, it is the world's only scaly mammal. Which I think 10 out of 10, just for that, because of, if you're the only one, it makes you very special.

Ellen: How has everybody else not figured this out?

Jack: Exactly.

Ellen: What are you all dragging your feet on? Get with the program. I wish sometimes when I look at the way that pangolins have their scales, armadillos, have a carapace, porcupines have quills, looking at all of the different defenses that animals have in ways that they protect their body. I feel like humans sort of [00:25:30] didn't understand the assignment a little bit. I feel like we missed a class or two.

Jack: We're just squishy.

Ellen: And squishy everywhere!

Jack: Yes. Nothing, not a single part of us is designed to sit. Like if I fell off something I could die, this could drop out of a tree and we just keep on walking.

Ellen: No fall damage, zero.

Jack: So yeah, they kind of have scales along their entire body. And they're perfect design because they live in, as I've said, Africa and Asia, where there are large predatory animals and not just large predatory cat go for these guys, you'll have chimpanzees. You'll have all sorts of big, clever, smart thinkers, trying to work out how to get to them.

And so to have scales, which you can wrap yourself up in a ball, hide yourself away. You're instantly like a bowling ball. You're protected. You're fine. They're made of keratin. So same as things as like our fingernails, rhino horn...

Ellen: Hair.

Jack: Hair. Yes.

Ellen: I got it. It's right there.

Jack: We've all got a little bit of pangolin in there somewhere.

Ellen: We've got the making, see what we could have been. We could have had it.

Jack: Yeah. And instead we just use it to style and cut and look fabulous and pretty, but I'm like, we don't need that.

Ellen: Well, that part is pretty fun.

Jack: I mean, I am sitting here on the hottest day of the year, so far in Scotland, like sweating and my hair, like not looking at it's best.

Ellen: Speak for yourself. No, I've got, we got Florida humidity. It's, it's rough out there for people with curly hair like me. We could have had both, though!

Jack: Yeah, they have little hairs. They have little tufts of things sticking out so we could have done the same. And I think, yeah, it's this perfect [00:27:00] defense mechanism of wrap-up in a ball and that's just the first of the many features I think justified the 10 for the pangolin and someone I interviewed for my podcast, Dr. Morgan Hauptfleish, who works in the Namibia University of Science Technology, something he summed up perfectly for me and why they are so effective and brilliant is that they have a cumulative impact on their environments.

He would say as much as elephants. So yes, I think really interesting because their design doesn't just benefit them. It benefits everything round about them. So for example, you have things like they are, insectivores, they eat insects. They can have these big, strong claws that kind of dig away at the termite mounds or wherever it is they're trying to get their food. They have long tongues then that they can fwoop! in, grab the food out and pull it in. And then inside their bodies, they have spikes kind of down their digestive tract to grind everything up. Which I think is really interesting.

Ellen: That is interesting. I've never heard of that.

Jack: And the tongue goes all the way into their body. It's I think the length is at least the length of their body and it will roll up and they have a little special poach that they can hold that in.

Ellen: Mm, a tongue pouch.

Jack: I wish you hadn't phrased it like that because it was interesting until you went " mm, tongue pouch". That makes it weird. That makes it weird. Do we have to take a point off now? So yeah, they're designed in a way to perfectly get the food that they want. And that then knock on effect is insectivore is very important for controlling bug populations that were going to destroy habitats and do all sorts of things. So perfect for that. They also, one of their main activities is [00:28:30] burrowing. So in Namibia and other places where they need to get under the ground to kind of stay cool, have a constant temperature to look after their young, they're designed with these big claws to dig, get under there. And then obviously the knock on effect of that is then by digging boroughs, you provide shelter for other animals.

Things like porcupine, tortoises will hide away in them. They also turn up the land. So for plant life and things, keep things going that way. And obviously in places like Namibia as well, where there's very little rainfall, anything that lets water underground when it does fall and kind of soak it in is also a benefit for the ecosystem. So my argument there for 10 out of 10 is that they are perfectly designed for what they need to do. And then the knock on effect is then everything else benefits as well. So I think it's a strong one for me, personally.

Ellen: Such a good ripple in the pond. Like just a nice little pebble that falls into the pond and makes a big, beautiful ripple. You're talking about anything that lets water sort of soak up underground, do their boroughs flood?

Jack: I think in Namibia, they have been experiencing a lot of drought for the last few years. So whenever it does rain, I think it's less an issue of flooding and the way that I've always been kind of thinking about it is to get this water underground is a benefit. And I haven't actually thought too much about the flooding aspect. I mean, they're nocturnal, mostly nocturnal. They'll kind of come out sometimes a little bit earlier, a little bit later, but they are mostly nocturnal. So I suppose they're out and about a lot of the time they do have quite large home ranges. They'll dig burrows kind of freshly. So even if it does flood, I don't think it's that big of an issue for them.

Ellen: Maybe [00:30:00] they'll just move on. Find somewhere else.

Jack: I think they just move on. I don't think it's a huge issue.

Ellen: Okay. That's good to know.

Jack: I mean, well, there's this thing, you're like, it's not a huge issue, but also it's probably cause climate change, they don't have rain a lot. So it's kind of like, it is an issue because it's not great for them in terms of that, but yeah.

Ellen: Zoomed out, bad. Zoomed in, not that bad.

Jack: Yes. Yes, exactly.

Ellen: Okay. So the pangolin is great at digging in the ground and burrowing, they're great at eating bugs, are they sort of limited to just like ground-based movement or do they have a little bit of like ability to like climb trees or maybe swim?

Jack: They are shockingly swimmers. In terms of climbing trees, it's more of the kind of Asian species are semi arboreal. The kind of ground pangolins, giant pangolins I think stick mostly to the ground level. Um, just cause it's different habitats that they've adapted to, but in terms of water, they can hold air inside them and kind of float. They kind of help themselves kind of float along. So they are actually quite effective swimmers as well. So.

Ellen: That's so cute!

Jack: It's a bizarre one. And I think it's a strange thing because you think, why would they need to do this? This doesn't seem like something they would need to do, but they can do it!

Ellen: Just in case.

Jack: So again, they've chosen all the best elements of everyone else and smooshed it together to go "this is us and we're perfect."

Ellen: Yes, exactly. You mentioned that they're are nocturnal. And just thinking about the way that they look, I know that they have little tiny eyes, so I would assume they're not super great at seeing do they have ears?

Jack: So that has [00:31:30] actually reminded me of something I meant to say about eating bugs. Another plus for the pangolin is that when they are eating termites or insects that might sting or bite or be nasty to them, they have little muscles, so they can close up their nostrils and their ears so they can fwoop! them closed and then nothing can get in and bother them and sting or be nasty or leave any marks.

Ellen: Airtight.

Jack: Exactly. The argument for them is much like their nostrils. It's airtight. Like, there you go.

Ellen: Shut down!

Jack: Drop the mic right there, done.

Ellen: Does this like kind of render them like completely devoid of any sensory input? I would imagine if you're, you've got your eyes closed, ears closed. I mean, that kind of leaves you blind, right? Like going through with essentially no sort of sensory input.

Jack: I mean, I, I suppose it's when, when they're eating. So I suppose it's probably not the biggest of issues.

Ellen: But it's like, you're already eating. So like mission accomplished. What more do you need?

Jack: Exactly. And worst comes to worst. Someone grabs you, some big predator, it comes up behind you fwoop! into a ball, all bases covered. There you go.

Ellen: You're fine. 360 degrees of coverage that way. Did they ever use those big digging claws, like offensively? Like, is that also a weapon of sorts?

Jack: Something on my podcast, I was talking recently to Arnaud Desbiez who works on the Giant Armadillo Conservation Project and the Giant Anteater Project. We were talking about tamanduas and anteaters and kind of how they use those claws. They're kind of fairly docile, friendly, nice kind of creatures. But if you [00:33:00] kind of push them, they kind of do that thing where they stick their arms up and you kind of look a bit nasty.

Ellen: It's a famous meme.

Jack: Yes! And like, you don't want to mess with them when they do that, because those claws could take a serious chunk out of you if they got right in. I have not heard of stories of this, I think pangolins are very kind of defensive. And I think it doesn't work always in their favor. And I would have knocked a point off for that, but I think that's ingenuity like once they ball up, they kind of stick like that. And so they're easy to then pick up and take away. Cause they're not big fighters. They don't fight. They don't really flight. They just kind of hide. Yeah. It's not really an offensive tool.

Ellen: Sure. That makes sense. I mean, that brings us to ingenuity. I mean, let's go ahead and get into it, you know, ingenuity for us is behavioral adaptation. So this is things the animal is doing with their body to solve problems that they face. Not get eaten. That's again, you know, but these are the things that they're more actively doing. What would you give the pangolin out of 10 for ingenuity?

Jack: So this was a tricky one for me, because the problems that they make for themselves are not problems they have with other animals, necessarily their problems they have with one very big problem animal, which is us. So I feel like, I feel like I need to knock a couple points off, but also it's not really their fault. So I'm going to say I was giving them an eight for ingenuity, which I think is still a good mark. And I think it's still fair.

Ellen: Strong.

Jack: Yeah. And in terms of the plus sides, you've got things like the bowling behavior generally, usually pretty good. You've got the burrows to kind of keep [00:34:30] themselves and their young safe, so they'll burrow down. And the reason they do that is to kind of get to a cool temperature. They can hide their young, they have one occasionally to meet usually one Pango pup, which is the name of the babies at the time.

Ellen: Are you saying pango pup?

Jack: Yes.

Ellen: Wow.

Jack: Which is spectacular in the grand scheme of baby animal names.

Ellen: That's a great one.

Jack: Yeah. Puppies may be cute to look at and be like, oh, look at that puppy. No, but the name, no. Pango pup. Better. So they will bury under the ground. They carry their young on their back. So when the young are born they're very vulnerable, they're little, their keratin scales, they don't harden for a few days after they're born. So they're kind of squishy. So yes, they carry them on their back to keep them safe. So all kinds of ingenuity pluses, I would say there, but then the negative side of that is rolling up in a ball makes you an easy target for humans, because we can just come along, pick it up and do whatever we want with you.

Ellen: Now you're just portable.

Jack: Yes. And the main threats to pangolins are things like trafficking and so not great. And also this is kind of a sad fact about pangolin, which is a changing landscape, really affects them. And the bowling thing works really well most of the time, but not only does it open you up to being picked up and taken away when an electric fence or something comes along and divides, your habitat, the problem pangolins have is their protective behavior. Obviously balls up, they will kind of walk into a electric fence. If they hit that they're not like a big deer or an [00:36:00] elephant that will kind of bounce off. They called their little hands up in front of them. And so what they'll do is they'll hit the wire, hold it, and then they're scared. So they'll ball up and wrap around the wire and then electrocute themselves. And that's a huge issue like in South Africa, about 13% of pangolins a year are taken out by electric fences. And so it's a huge, huge issue. And it's one of those things where it's like, they can't really be blamed for that. That's not their fault that a fence is across their landscape, but it does go to show the weak spot of the defense mechanism of balling up in that you're portable, and that when you hit something that gets inside that ball, it's not beneficial. So it was hard to take points off them for things that aren't their fault.

Ellen: Right, yeah, it's not the most foolproof possible strategies . You mentioned earlier that they're up against some very clever predators in their range, like chimpanzees. Can you think of any instances of like a predator that has like figured out the pangolin? I know sometimes for something like an armadillo or something, there will be some predators that have figured out how to flip the armadillo over or maybe get underneath them. Or sometimes you'll see this happen where like a predator will figure out a counter to the animal's like strategy. Can you think of any examples of a predator outsmarting the pangolin or otherwise like getting through those defenses?

Jack: In terms of like larger predators, I think lions and larger cats have a big problem because really they are restricted to the ways that they can get into that ball.

Ellen: Not high dexterity.

Jack: Chimpanzees, I think a bit more clever. They have a bit more use [00:37:30] of kind of pulling things apart and getting in and about, but actually the kind of, one of the main threats, I think in terms of animal things that can take advantage of the pangolin is the scales. The way that they line up there are gaps of fleshiness in there. And so different sorts of parasites can get in. And I think particularly for young animals, that's an issue when they kind of fall under the scales or if they get in the center, It's not necessarily the big animals you would think about that are going to come along and outsmart them. It's the little things that can sneak through to the defenses.

Ellen: It's Luke Skywalker getting into the, a little vent on the death star. Exactly.

Jack: That's the perfect, because it's, the ball is the Luke Skywalker shooting that one little whoomp! down, use the force kind of hope for the best moment. Yes. So I would say bigger predators, not too much. I mean, we've talked about this on my podcast a lot.

We have a series called ReZOO where we talk about, uh, we review zoos, which I think is not as good a pun as yours, but it's good fun. She is terrified of chimpanzees, my cohost, Jodi, because she just doesn't like this. She thinks they're big and they're smart. And they're strong.

Ellen: Is it maybe an uncanny valley thing?

Jack: Maybe? I mean, I wouldn't want to see the fight between a pangolin and a chimpanzee, cause I don't think it would end particularly well for the pangolin but the scales, they do what they can, they do what they can.

Ellen: Yeah. And they are, you know, by rolling up in a ball, they are sort of maximizing the level of coverage they're getting. It's not like they're just kind of relying on it passively. They're actually like, okay, I have these skills. I can use them to the most possible advantage by just closing up all those gaps and go and full defense [00:39:00] mode.

Jack: Yes, exactly.

Ellen: Like a turtle strategy where you like load up all, like you put all of your points into defense and you don't do anything. Just like stop and wait and let the enemy like tire themselves out and exhaust all their resources. And then once they're like weakened and you're like, boom.

Jack: But the thing is they don't have the boom. They, they will just kind of go "is it gone yet? Uh, okay, now we're good. We're good."

Ellen: They're like the pacifist, they're so peaceful. I mean, we're not ants or termites. So to us they seem very benign and passive and peaceful and gentle. Um, if we were termites, we would probably see them quite differently.

Jack: Yeah. Actually, that's a very good point. It's all about perspective. It's all about perspective. And you know, if, if it was Just The Zoo Termites Of Us, that would not, that would be...

Ellen: Any termites listening, I'm so sorry. This is probably a rough episode for you.

Jack: Deep condolences to the 20,000 of you a night that get eaten by pangolin. I'm so sorry. So sorry.

Ellen: Menace to the termite community.

Jack: I was going to say if we did an in memoriam, like the Oscars type style, black and white images of termites, we'd be here for about six years. So we can't even.

Ellen: Do a slide show the best of, but it's just like the same termite over and over again.

Jack: Just from different angles. They'll never know. They'll never know. Just use the same picture.

Ellen: They can't tell. So the last category that we rate our animals on that, I feel like I have strong feelings about the pangolin in this category, is aesthetics.

Jack: Now, that's interesting.

Ellen: I have a [00:40:30] feeling, I probably know where you're going to go with this, but what do you give the penguin out of 10 for aesthetics?

Jack: Well, I, this was my lowest category, so I don't know. I'm intrigued ...

Ellen: That's surprising to me. I promise I'm not going to be mad at you. It's okay.

Jack: So the reason I put it lowest is that yes, it has the pluses of the, I'm building the tension there. So you can finally hear the number in a second. The reason that I kind of put it lowest is that yes, it has the scales. Yes, it has the cuteness, which is a plus, but listening to recent episodes about things like jewel wasps, or like the most gorgeous, beautiful thing in the world in terms of colors and showing off. Pangolins are mostly brown beigey, dull kind of colors. They're not a big show.

Ellen: Gotcha.

Jack: So in terms of aesthetics, while it's pleasing and interesting, it's not like a, I was going to say, this is how, you know, I'm too into animals. I was going to say, it's not a cassowary and then some people are gonna to go like, cassowaries aren't good looking. But to me, they are, to me, they are. So, yeah.

Ellen: It's the bright blue. It does something.

Jack: Exactly, the kind of crest, it's not got that kind of showiness to it. And so that's why I have, I mean, I'm building this up to be like a two, it's not two, it's like a seven.

Ellen: That's good still!

Jack: Uh, I think I was trying to think of like, if I was reading, like I'm a big like movie person. And like, I like to like come away from a movie and be like less than five is like, okay to bad, five and above like five is like ehhh, six is fine. Seven I think is good,

Ellen: But could be better.

Jack: Eight, great. Nine, excellent, 10, [00:42:00] perfect. So for me, I think it's good. Not great. So that's why I feel that. Yes. So I don't know. What were your strong opinions?

Ellen: So, earlier you were talking about how, like you did a lot of different things, but like animals were always sort of the thing you came back to. And, you know, I've gone through a lot of times in my life where I focused on different hobbies, like creative hobbies. So I've done art and photography and, you know, all sorts of different stuff. And one of my favorite drawings I've ever made was a drawing that I did of the pangolin and I immediately regretted starting this drawing because then I realized I had to draw every single scale and then I shaded it with stippling. So I had to draw little tiny dots on every single scale and shade, every scale individually with dots, which is a terrible idea, and I'm quite pleased with how it turned out, it ended up looking very nice, but it took me many, many hours.

And just throughout the process, I think of like drawing that it made me really focus on the individual little pieces of the pangolin and like, the reason I think they're so beautiful to me is that first of all, they have so many curves, you know, like everything about them has a sort of swooping like curve to it. Almost like, like a golden ratio sort of thing. You know, like it has that sort of very smooth because they have like a dome shaped back, but then also a curvy tail, their nose is curved their like claws are curved. And like everything kind of follows this sort of like flowing emotion to them. And then just like the icing on the cake for me is [00:43:30] their scales because they look to me like, like flower pedals. Maybe Lotus pedals or something, just because of the way that they overlap. But they also slightly like float over each other, you know, like they're not completely touching and it just looks like a, maybe a less romantic way to say it would be a pine cone. Still look like a pine cone..

Jack: The nicknames come in thick and fast for them. So like their name pangolin comes from the Malay word pengguling, which means to roll up, makes sense, but like the nicknames are like scaly ant eater, like walking pine cone, like all comes together in the aesthetics category. All makes sense when you're like, yeah. Okay. Yeah. But no, I think that's a very romantic, but beautiful. Like I see that, like I do see that and I do think I agree, but I had to be harsh in a category. So I have to, like, I had to be cruel.

Ellen: I don't say this to try to change your mind. This is not, I'm not, I'm not trying to convince you or anything. This is just, these were all like thoughts that I have about them when I look at them that I just, like, haven't had an excuse to, to like put into words on the podcast yet. So I'm just like, while we're here, here's all my thoughts and feelings.

Jack: Exactly, exactly. Get them out now. And then yeah, if you do, you'll have, we'll have to do a pangolin part two once we play, because I feel like I can tell that you're excited by it, so you were like, "we'll have somebody!"

Ellen: Yeah, absolutely. Well, you mentioned there's eight different species of penguins, so.

Jack: We need to get specific.

Ellen: Yeah. There's room to zero in on them.

Jack: Eight episode series, there you go.

Ellen: I'm not opposed. Um, but yeah, I, you know, I, I do see what you mean. I will concede there are, they don't have the flashy colors. They don't [00:45:00] have the flashy markings, would love to see a little bit of creativity. Can you imagine if they had all that stuff going for them and also some sort of like beautiful, bright, like coloration.

Jack: I mean, it would probably not work in their favor.

Ellen: You are correct.

Jack: But also it's like, it's one of the, it's such a hard category to rank aesthetics. Cause you're like, for me personally, they're not exciting to look at necessarily in terms of colors, but that's the point, right? It's like watching a black and white film. You're like, oh, well it was meant to be like this, but also, I prefer if it was in color, but also it might not actually be better if it was in color, like this weird, like--

Ellen: "Was this the artist's vision?"

Jack: Yeah. And for like, for me, like I had, I feel like I'm a very visual person. Like I like visually stimulating things. And so there is a lot to look at, but do like a tie dye one or something.

Ellen: Just one. Do a limited edition release of one--

Jack: Come up with a new pangolin.

Ellen: Get our scientists on it. Immediately.

Jack: Ship them off to Jurassic park or something. Get them to work on it. It'll be fine.

Ellen: I do think that like with the way that the scales are so like geometrically placed and aligned is like mesmerizing. I feel like you could just stare at them all day. Like you can kind of get lost in them. It's perfect.

Jack: And the fact that they then ball up perfectly and it doesn't look like when a hedgehog or something kind of, you kind of got spikes and it looks great aggressive and like armadillos have this similar thing going for them that when they ball up, they kind of just look like a little orb. So it's not unique to them that they can just from fwoomp away into this little so kind of [00:46:30] orb, but it kind of, yeah. I mean.

Ellen: Become orb.

Jack: Become orb. I mean, one more bad news story and that's going to be me. You'll never see me again. Just become orb, that's, it that's me.

Ellen: This whole episode has just been as pondering the orb.

Jack: The orb. That's just, I feel like there's a whole series there as well for you. You can just do creatures that become orbs.

Ellen: And we call it pondering the orb. Pondering my orbs, the series.

Jack: Yeah, that's the one.

Ellen: We've done roly-polies so we'll do like roly polies, uh, armadillos. We got all sorts of conglobating friends. I love that word. Conglobate. Do you guys use that word a lot?

Jack: I've never heard it before, but I think I'm now going to use it for everything because Wordle was expanding my vocabulary already, but it was stuck to five letter words. This is great. This is much better. This is the level I need.

Ellen: I try to make sure we, uh, learn a new vocab word every single day. That's what people come here for is vocab lesson actually.

Jack: Nothing to do with the animals.

Ellen: No, the animals are just a context to put your new vocab words in. You mentioned that you work with conservation for pangolins. So what is the conservation situation looking like for pangolins in the world?

Jack: So this is like my big, because I've worked in zoos and aquariums, all these things. I think conservation has to be the heart of everything we kind of do because if people come and see these animals and whatever it is in a zoo, and there's no purpose to it, it just falls flat. And it's, there's no point in [00:48:00] having the zoo at all. So I think it's really important to kind of, whenever you're talking about animals, place that in context, place this kind of conservation message around them. And I think for the pangolin it's so, so important. As I've said before, I think I mentioned they're the most traffic mammal in the world, and that might sound like, oh, that's just kind of one of those buzz word titles that they put on things, but that is not the case at all. Over the last 20 years, about a million pangolins have been taken from the wild, so much so that kind of the trade has shifted. They've exhausted the species that are in Asia, they are, I think three of the four species are listed as critically endangered by the International Union for the Conservation of Nature. The fourth species is listed as endangered. So they're kind of spent in terms of being taken and so turned to the African species. So they were kind of getting hit with the trafficking and all the other threats and kind of the changing landscape, as I mentioned with the fencing before, it's not a good situation for them. In the African species I believe two are endangered, two are vulnerable, so it's not a great picture for the pangolin. And I think I like, I love them so much.

And I think there's a lot that everyone can do for them. The major threats are things like trafficking, which I didn't know how individuals could deal with trafficking on a day-to-day basis. I wasn't aware of that until I spoke to someone on my podcast, all about trafficking and they were talking about how trafficking in terms of animals takes place along the same channels as artwork, as drugs, as all of the other sorts of trafficking that goes on. So if you see anything that could have been trafficked, if you see someone who perhaps looks like they're in a situation [00:49:30] where maybe they kind of are in a dangerous situation and without getting too dark flagging trafficking, or movement of things illegally in any way, it can help to bring down the trade of animals and the trade of pangolins. Here in Europe, it's not as big of an issue, but a lot of trade going to Asia because they have the keratin scales they kind of are used in a lot of traditional medicines. So there's that kind of element going on there.

Other threats, things like hunting for bushmeat and things is a lot less, but I think it gets grouped in the big threats. And then you have the changing landscape. So climate change with the building of habitat fragmentation and things like that. There's all sorts of things going on that are kind of changing the landscape, changing the areas that they can move and live in. And so it's a huge, huge issue. All of those little things that when people say recycle or reuse or do this for the next that they all go on to impact more species than just the big charismatic megafauna that you see advertised, it affects more than just tigers and elephants and whales. It affects the little things like the pangolin as well, which are so important. Amazing.

Something that I like to highlight, especially in terms of the pangolin, because they are, the kind of leaving message of conservation for them is when you're talking about pangolin, I think a lot of the time it's talked about in a way that blames or points the finger at certain groups of people. Points a finger at China or Vietnam because they do this or they do that, or they do the next thing. And I think that's a really dangerous narrative to establish because when you start pointing fingers at whole countries, that's not how conservation and the consumption of animals and wildlife products actually works. It's kind of like one of those things [00:51:00] that if you demonize all these people, it can be really dangerous. And it kind of disincentivizes the people who are blamed and it can turn into borderline if not full racism or offensiveness, if you are kind of pointing these fingers. So be careful when you're phrasing, pangolins are trafficked or pangolins are doing this or pangolins are being used in these ways by these communities, or they say, be careful how you speak about it and do your research before you really start pointing the finger, because the waters are very muddy there. And it's not just everyone is using pangolins in the countries where they're being shipped to. It's not that at all. So that's kind of my other message I like to highlight is just be like really careful with how you freeze the messaging around certain things, because it can get dangerous and a bit, phrasing can be a bit funny in terms of wildlife conservation.

I guess that kind of links back to the politics of, I think there's the benefit of having a kind of political minded, my like conservation minded, all of these minds coming together. I'm like, please just speak kind to one another when you're talking about conservation and just be aware that we don't have to fight each other to make positive things.

Ellen: Like this was something we were talking also to Dr. Christine Wilkinson about was that, um, you know, conservation requires a lot more human empathy than I think is usually presented.

Jack: Yes. There's some things where it can be confusing, why people use keratin for traditional medicines or whatever it is, but shouting out them maybe isn't the best solution, like having to sit down and having a discussion. And I think, especially when it comes to like, there's often pictures painted of kind of groups in Africa, kind of like, oh, they use pangolin for traditional ceremonies, but at the end of the day, and this is coming from someone who loves them more [00:52:30] than anything else in the world, one pangolin being taken from the wild is not going to end the species forever and ever and ever. It's when it gets scaled up and kind of all of these threats combine that then becomes an issue. And so it's really this kind of tricky, complex muddied narrative that you've got to pull apart, these threats. And so just be careful who you're talking to and talking about and who you're including in the discussion about conservation, because it's something that's really important to me to try and highlight. I don't know. It's something that I like to think about a lot. Yeah.

Ellen: Yeah. And here in here in the United States, too, so we talk about is how, like people that are indigenous to this area have been in equilibrium with these animals for thousands of years. So, cultures and customs have been in a state of balance for so long. And then once industrialism starts to play a role in it, everything gets just scaled up way beyond what the ecosystem can handle.

Jack: Yeah. And I think the best thing we can do, I kind of took a dive into like the negatives, but I think the positives that we have to kind of lift back up in is that there are so many ways that we can support the pangolin positively in things like, yeah. Changing your behavior to do with climate change. Just talking about the pangolin and other unusual creatures, I think is so important because even the big charities, obviously you see kind of them promote tigers or whatever it is. I keep bringing them up and they are important and they're wonderful and they're fantastic. There are other animals out there suffering as well. So talk about the weird things. Talk about the weird stuff that people don't think about and bring that stuff up. Yeah. Support charities that maybe are developing new eco-friendly fencing because obviously we talked about habitat fragmentation being an issue. There are [00:54:00] fences that can be employed and used in ways that allow pangolins underneath so they can just scooch underneath. So there's all of these different things and charities and stuff. You can kind of support in a positive, more uplifting way. Then it's all doom and gloom. It's not all doom and gloom. There is a lot you can do to help save these wonderful, beautiful, amazing things.

Ellen: I love a healthy dose of conservation optimism.

Jack: Yes, I think that's, I just had Julia Migne from Conservation Optimism, the kind of like University of Oxford kind of movement on my podcast. And she's just like, yeah, we were, I came away from the conversation like I often get down in the dumps about certain things and I think it's. Yeah. You feel your feelings and feel the emotions and feel the anger or the sadness or the confusion about conservation, whatever it is. But the end of the day, try and frame it in a positive way. Cause like you just get on so much better. If you're positive, you make more positive connections, you meet more amazing people and you just get along better in life. If you try and frame it in a positive way, all right.

Ellen: Or in like a hopeful way, right? That's like, there are things we can do. You don't have to just, well have yourself a wallow, wallow it out, wallow it out. And then, and then we'll all pitch in to make everything better for everybody.

Jack: Exactly. You can tell you've done 150 of these cause you're able to link back to the very first thing we talked about. So smoothly.

Ellen: Callback baby! Comedy 101.

Well, Jack, I would love it if you could let folks listening know, where they can find your podcasts, where they can hear more of your [00:55:30] conservation work and listen to more about pangolins and all the other delightful critters that you spotlight on your show, let folks know where they can find you.

Jack: Yes. So thank you, everyone. For anyone who's kind of forgot my name throughout, I am Jack Baker. Yeah. I host Pangolin: the Conservation Podcast, which is a look at all underappreciated under acknowledged members of the conservation community, whether that be unusual species. So we focused on things like armadillos, bison reintroduction, we've talked about interesting, weird things. Water voles, red pandas we've talked about, but animals that are kind of popular. So we talked about giraffes, but we kind of reframed it on like, looking at how conservation, people don't appreciate how endangered giraffes are. So we sometimes focus around weird animals or conservation stories. We also focus around people. So, and we talk about communities that are affected by conservation. We talk about people who are experiencing drought and how they are forced into these kinds of wildlife conflicts and how we can resolve that element. So all these kinds of underappreciated elements are up for discussion.

And the first six episodes are all about the pangolin. Um, so if you have gotten a taste, they have experts on every episode. It's not just me. I sit and interview someone much like this, every episode, some of my favorites about tapirs and koalas and all sorts of stuff. So lots of good stuff going on over at Pangolin: the Conservation Podcast, which is on Spotify, Google podcasts, wherever you're listening to this, it's probably on there as well.

Ellen: I've had a lot of people like reach out to us and let us know that like listening to this podcast has made them feel like they want [00:57:00] to get back into either studying or working with wildlife, you know, or doing something that can help make the world a better place for animal friends. So, um, you know, that's an awesome way to start.

Jack: Yeah. And I think it's good for me and I, listeners, you are coming on a journey with me. Cause I just get, I basically send invites out to people who inspire me and I'm like, they say yes and then I'm like, okay, I'm going to ask them all the questions I've always wanted to ask. So it's, it's a great time. It's sometimes a laugh, sometimes more serious, sometimes whatever it is, but I just like it's, it's great. I love it. I mean, not to bring myself up. It's about like, I just love having the conversations. I hope people like listening.

Ellen: No, hype yourself up. That's, set those expectations sky-high.

Jack: Exactly. And if you want to reach out to me to chat about anything, if you have questions about what I've said, you can get me on Instagram, Twitter, Facebook, LinkedIn, I'm @pangolinpodcast on all of them. So reach out, tell me you love pangolins, tell me you disagree with something I've said, my rankings, ratings, whatever it is, I'm more than happy to hear it and I will discuss. More than happy to discuss. And yeah.

Ellen: Well, thank you so much, Jack. I highly recommend, um, I'll have links to everything in the show notes as well. So anybody listening to this episode can open that up and click right on through. Uh, thank you so much for your time and your knowledge today. I'm glad I saved pangolins. Because this feels so fulfilling. It feels like a culmination of like [00:58:30] what, uh, what we've been waiting for, baby.

Jack: Well, I'm so glad --I hopefully you're smiling. But you might just be being polite. I hope all the listeners are also smiling and were not disappointed.

Ellen: Oh I'm not just polite.

Jack: And there's, there's so much more out there about them to learn. And this has just been like, I feel like we've recorded for an hour, but we could have gone for 2, 3, 4 or five hours if we really want it to get into the nitty gritty. So, or worst comes to worse, you can come on my show and we can talk about it. Then--

Ellen: The overflow!

Jack: The overflow, just like people can come to this one part one, and then any questions you had leftover, we can do questions.

Ellen: Absolutely! Well, thank you so much for your time, Jack. It's been a delight and we will catch you later. Thank you so much.

Jack: Thank you. And thanks everyone for listening. Hopefully you'll hear me again soon.

Ellen: Absolutely. Thanks Jack! Bye!

Thank you so much for listening friends. I hope that by now you have fallen in love with the pangolin along with us. If you liked what you heard today, it would mean a lot to us if you could leave us a five-star review on your podcatcher.

139: Jorō Spider & Day Octopus

Ellen: Hey everybody! It's Ellen Weatherford. 

Christian: And Christian Weatherford. 

Ellen: And we're here with Just The Zoo Of Us, your favorite animal review podcast, where we review your favorite animals by rating the m out of 10 in the categories of effectiveness, ingenuity, and aesthetics.

Christian: We are not zoological experts, but we do a lot of research and try our best to make sure we're presenting information from trustworthy sources.

And big ups to us for recording on time this week, it doesn't always happen. We, we made it happen this weekend. I'm very proud of us for that. Also I have a little bit of a cold, so I'm sorry if my voice sounds a little weird.

Christian: I don't have any excuses. I'm sorry. 

Ellen: You're just like that. Your voice always sounds like that. I think a lot of people like it though. 

Christian: Yeah.

Ellen: Including me, I'm at the top of the list. 

Christian: It's mostly in jest.

Ellen: Before we get into it for this week, I want to echo the announcement that we made on our last episode together, which is that we are collecting stories from listeners. So if you are somebody who listens to the show and it really means a lot to you, or you have some sort of cool experience that's related to the podcast that you want to share.

Like maybe you went on a really cool adventure and you listened to the podcast during that adventure. Or with somebody really important to you, or maybe it's inspired you to do something really cool. We want to hear about that stuff. So send an email to member stories@maximumfun.org or leave a voice message at (323)601-8719.

We're working on some special stuff that's coming up really soon. So you might get to hear your message shared on the podcast, or if you leave us a voicemail that might even get played too. So we don't usually do stuff like that. So this is a pretty cool, uh, opportunity. If you want to hear your voice on the podcast 

Christian: Yeah, for sure.

Ellen: And that's all I had to, uh, preface this episode with. So I guess we can get right into it. 

Christian: Yeah. 

Ellen: Christian, it's your turn to go first. What animal do you have this week? 

Christian: Let me just change over my active app on my smartphone. 

Ellen: Thank you so much for not, uh, specifying what brand of smartphone you use. Not only because we don't give out free advertising on the show, but also because I don't want to incite the smartphone allegiance war.

Christian: Not again. So I'm bringing what I would consider the animal of the quarter? Maybe? 

Ellen: It's a hot topic critter. 

Christian: It is, it's out there and that is the Jorō spider. Scientific name Trichonephila clavata and this species was submitted by Mick on Twitter. The information I'm bringing comes from national geographic.com and Penn state extension's website@extensiondotpsu.edu.

Ellen: Nice. 

Christian: Yes, you'll notice I'm not including Animal Diversity Web this time. 

Ellen: How have they harmed you? 

I think it has more to do with the taxonomy of this species having changed in recent years. 

Ellen: Really?

Christian: Yes.

Ellen: Interesting. Sorry, animal diversity web. You're going to have to sit with a phone out. We'll tag you in next round.

Christian: I think it was its genus that got updated. So I couldn't find it under its current genus and I didn't do any further looking beyond that. 

Ellen: That's fine. It sounds like you got what you needed so we're okay.

Christian: So for those maybe unaware of spiders --

Ellen: have you heard of spiders? These things are so wild. You're not going to believe it. 

Christian: Um, generally speaking, eight legs. 

Ellen: And why do you say generally speaking isn't that like a defining characteristic?

Christian: I was, I was supposed to have other things in that list. And then I drew a blank 

Ellen: Though, I do love hedging my bets, but I always say things like mostly, most of them have a leg--

Christian: Most things die. I don't know. Um, what's the term? What is, what is the high like classification that spiders belong to, along with like insects and such --

Ellen: Animalia.

Christian: That.

Ellen: Okay, am I getting warmer? (laughter) Arthropods. 

Christian: Yeah, there it is arthropods. So they have an exoskeleton, I suppose you would call it, no bones,

Ellen: Nary a bone in sight.

Christian: No bone zone. 

Ellen: No bone zone! My animal this week doesn't have bones either! 

Christian: I actually don't even know what it is. So that'll be a nice surprise for me too. Whereas the listener has at least seen the title of the episode.

Ellen: That's true! Oh what a fun experience.

Christian: A lot of spiders will spin webs or have spider silk, will eat other bugs and insects and such some more interesting things. But this one is a spider that including its legs is about palm sized. 

It's big!

It's pretty big spider!

Ellen: It's real big!

Christian: Um, the females are larger and they are neon yellow with silver bands with a little splash of red at the end, and they have spindly legs.

Ellen: Spindly is a good word. They're long and pointy. 

Christian: As opposed to something like a tarantula has very, I dunno, beefy legs. 

Ellen: They're very pointy. 

Christian: Yeah. Where they're found. Now, this is a big, important one where they are natively found, that range includes Japan, except the northern most island of Hokkaido, North and South Korea, China, Taiwan, Vietnam, and India. So that's their native range. 

Ellen: Eastern, Eastern Asia. 

Christian: Yeah. However they're introduced range in the U S includes the states, Georgia, Alabama, North and South Carolina and Tennessee. 

Ellen: Okay. That's kind of creeping our way. 

Christian: Yeah. And it's that range that makes them a hot topic right now. 

Ellen: Gotcha. 

Christian: They seem to have been introduced into that area around 2014, likely in shipping containers from Asia to Atlanta. And those unfamiliar Atlanta is not near the ocean, but it is a big hub for all things. 

Ellen: Everything goes through Atlanta, everything in the south goes through Atlanta, 

Christian: Especially commercial airlines. 

Ellen: Oh yeah. They have like the big like airport that -- everything goes through Atlanta.

Christian: They're taxonomic family is Araneidae 

Ellen: Araneidae? I would say Arandeidae. 

Christian: I actually looked up the pronunciation and spelled it out for myself and everything.

Ellen: Oh, I'm so proud of you!

Christian: Uh, other things in that family are other orb weavers spiders. And just to note on that term in this usage orb means round not spherical. 

Yes. So it was more of a 2d descriptor than a 3D. 

Ellen: Okay. I get, I get it. We're not pondering this orb. Next episode, next week, lots of orb pondering. 

Christian: And let's get into our first category for our new listeners. That category is effectiveness and this describes physical attributes that kind of helps them do the things that you like. I'm giving an eight out of 10. That's pretty good. So the biggest thing we think about with spiders is spider silk, or at least that's what I think about first.

And this one does have spider silk and it does build webs and the orb weaver kind of moniker, it talks about that classical spiderweb shape that you think of probably.

Ellen: It's gorgeous.

Christian: So usually you'll find these spun between a few branches or something. Big web designed to catch things that are flying. Basically.

Ellen: I like that orb weavers do this because they have effectively just optimized the hunting process where they're like, I really don't feel like moving that much. I just think I'm not gonna do it. I'm going to let my prey do the flying for me 

Christian: Yeah, that actually comes into play a little later too. 

Ellen: Or weaver webs, anybody living in the south is intimately familiar with orb weaver webs because we have here the golden silk orb weaver, which we also call banana spiders, which are known for making these massive webs that they often will spin across walkways and pathways where people will walk and they really don't care whether you're going to be walking there or not.

They're going to make their web there and you're going to walk right into it. Every single time. You get really, really good at like, detecting these webs before you hit them. If you do a lot of walking around in the south.

Christian: If you're very tall, are typically the first person walking in your group of people in a forest.

Ellen: You get real good at it real quick.

Christian: That was the role I often played. The web clearer. 

Ellen: The web clearer. 

So before 

Christian: I keep getting too much further, I want to talk about a little bit more about why this species has come up so often. So something of a... I'll call it hysteria, I suppose, around this introduced species into this part of the United States. So it's being talked about just because like, ah, new spider, big spider--

Ellen: New big spider. Babe, wake up. New spider just dropped. 

Christian: And you know, the question is, should we be concerned? Short answer's no. And one of the things that concerns some people is this next point, I'm giving them for effectiveness. And this is the ability of ballooning.

So this is when, when young they can let loose some of their silk, then the wind can carry them to other places. 

Ellen: Okay. So for some reason, I didn't think about it being a balloon made of their silk. Some strange part of my brain thought they were somehow inflating their bodies,

Christian: Oh no --

Ellen: Like turning themselves into a little balloon and a flight, cause I'd seen this word ballooning and just some part of my brain filled in the blanks and was like, clearly yeah, they blow up their body like a puffer fish or something and float through the air.

Christian: That's be pretty good. But no, they, they let out some of their silk, I don't know if it's an actual balloon shape or not. I think it just might be some little strands of silk because this is when they're, when they're young and it's very small, so it doesn't take much. But using that method, the wind can carry them for tens to hundreds of miles.

Ellen: They can't crawl that fast. So this is a big speed boost for them.

Christian: It spreads them out. 

Ellen: It's the end of Charlotte's web. Spoiler alert. I'm terribly sorry if you haven't seen that cartoon from the 1970s. 

Christian: And the next thing we want to talk about is their venom or more generally their bite. This is a big reason why you shouldn't really worry about them I suppose. So first the venom is weak. It's not life-threatening to humans and also the size of their fangs makes it difficult to puncture humans. So, if you are bitten by one of these it'll hurt, but it said to be less painful than a bee sting, and will generally, you know, self resolve without any kind of medical intervention.

Ellen: Right. Barring like an allergy, which naturally you could be allergic to anything. But yeah, they're really not that scary. I mean, like even our, even our banana spiders here that we have, we're not terribly scared of them. Yeah. 

Christian: And when we get to the next category, there's another reason you don't have to worry about being bitten very much.

But the next thing I want to talk about with effectiveness is their cold tolerance. 

Ellen: Oh, interesting. I guess you'd have to have that to be making the kind of moves they're making. 

Christian: Um, so this is a topic that was the subject of a paper that was released in recent months, that kind of spawned all of the news hype around this spider.

Ellen: Okay.

Christian: And that article was titled "Physiological Evaluation of Newly Invasive Joro Spiders Trichonephila Clavata in the South Eastern USA Compared to the Naturalized Cousin Trichonephila Clavipes" CLA-vee-pays. Cla..veep --

Ellen: Clava-pees?

Christian: That makes more sense, uh, by Davis and Frick in the year 2022. 

Ellen: Oh, that's, that's really fresh.

Christian: Yes. Um, I believe that second species is the golden silk orb weaver. 

Ellen: Oh, okay. And they said they called it naturalized, interesting. 

Christian: Yeah. That's why I think it was also introduced, but along like hundreds of years ago. 

Ellen: Sure, yeah yeah. A long time. It's been here awhile. They've settled in, they've got posters up on the wall, they've painted --

Christian: So basically this study was trying to see how well do they deal with, uh, cold weather, like the joro spiders versus the golden silk orb weavers and the joro spiders on top. So the joro spider, 74% of specimens survived brief freezes compared to 50% of the golden silk orb weaver. Which makes sense, considering where they're found in Asia. 

Ellen: True, they can get pretty far north.

Christian: Japan gets very cold, although not the most Northern bed of Japan, but still, you know, North Korea, South Korea.

Ellen: I mean, it's, it snows you know, like it, it gets real cold there, colder than it does here. 

Christian: And that cold tolerance is largely due to greater metabolic rate that helps them stay warm. 

Ellen: Oh, so they kinda got a little steam engine pumping in there. 

Christian: Basically yeah, so that wraps up effectiveness, moving on to ingenuity. This is the category that describes smart things, could be hunting methods, tool, use that sort of thing. I'm giving it a seven out of 10. Yeah. So personality wise, I suppose. They're not quick to bite humans. 

Ellen: I don't know of any spiders that are quick to bite humans. 

Christian: I think there are spiders that are unfortunately just positioned in places where if you come across them, they're probably going to bite you. Like we talked about like a black widow. They like to hide under places and stuff. So if you come in contact with them, you're probably accidentally grabbing them. 

Ellen: Right. You're probably already well within the danger zone. You are already being bitten. 

Christian: Oh my. I mean, we can't talk about ingenuity without talking about building webs, right? 

Ellen: Yes! It's great!

Christian: I had to get to that conclusion. It's it's a, it's almost tool use that we kind of take for granted with spiders.

Ellen: It's built in tool use. Spiders do some incredible things with their webs. They make beautiful works of art with them. Some spiders can be really clever about their positioning of their webs, but I would not say that orb weavers are among them because we always see orb weavers like in our yard or around our house or something, putting their webs in the least strategic places, they're always putting them like across doorways or like across a fence or somewhere where something is definitely going to be walking through there and breaking your web. Stop putting it there. And then when you walk through and break their web, they rebuild it in the same spot. They didn't learn from the last time. Stop putting it there. 

Christian: I mean, they can't have that kind of macro view of their universe. Right. It would be like some deity saying like, "ugh, stupid humans putting their planet in the way of a meteor."

 (laughter) 

Christian: Um, yeah. So the next thing I wanna talk about is they are passive hunters. So they build these webs and they wait for something to get caught in their web. They're not like actively hunting. 

Ellen: Sure. It's an active dismantling of that, like, entrepreneur grind- set like those, like you got to get out there every day. You got to wake up at five AM, go to the gym and I don't know, wear a suit everywhere you go. Then spiders are like, no, no, no, no, no, no, no. 

Christian: The opposite of whatever Kim Kardashian saying right now. Uh, and then finally they have a tendency to build their webs high up, which gives them an edge on other species in the U S range because not many other spiders do that in Georgia. For example, this study was largely conducted in Georgia, by the way. 

Ellen: Sure. Okay. So they're more like up in the higher, like a canopy maybe area. 

Christian: Uh, so yeah, that wraps up ingenuity and we finally get to our last category of aesthetics. This one is how interesting they look,, this can mean cute or cool. Again, 7 out of 10 on this one. So the females are large and colorful, but the males are smaller and mostly brown. 

Ellen: I thought you may have gone higher on this one because they just have kind of an edgy look. And I liked that. 

Christian: Yeah. Um, I've mentioned their spindly legs, uh, which makes me think of the banana spider, like you said, but, uh, also this might be a bit of a deep cut, but have you ever seen Jumanji?

Ellen: Okay. I personally haven't, I'm sorry. I know that's-- babe, I've seen three movies and one of them is Hunger Games. And I've already talked about that. 

Christian: Well, the premise of Jumanji, which you probably already know, but in Jumanji, there's this magical board game that makes, you know, jungle animals and stuff. Not all of which are jungle animals, but that's okay. And, you know, people getting sucked into the game, whatever. Well, at one point in the movie, giant spiders come out and they have those kinds of legs. And every time I see a spider of those kinds of spindly legs, I think of Jumanji. 

Mm, interesting. 

Ellen: You know what I think of when I see like a spider with cool spindly legs I think of that scene towards the end of the Nightmare before Christmas, where, uh, Jack Skellington is in the Oogie Boogie Man's lair and the Oogie Boogie Man has this big, like, it's like a roulette table that he's spinning and it's got a little like guns on it. And Jack Skellington is on the roulette board, like kind of crawling along. It it's spinning underneath him, but you know, that character has very long twiggy legs because he's a skeleton, right? That scene always makes me think of a spider crawling along. And because I also consider that to be a very cool character with like good character design. I think that also makes me feel warmer towards the aesthetics of spiders, because I see a spider crawling around and it reminds me of Jack Skellington dancing on a roulette table, which is cool. 

Christian: That is cool. It's just some miscellaneous info for these nice little spiders. They could potentially pray on problematic insects species that other spiders don't eat in the US.

Ellen: Well, that would be nice. I would like for them to do that.

Christian: I think they were seen they've been seen eating a type of stinkbug that other spiders don't typically go for and that stink bug can be problematic with our agriculture.

Ellen: Okay. That would be helpful for them because it helps if like the prey that you're able to go after isn't preyed on by a lot of other stuff. Because then that just reduces competition for you. 

Christian: Yeah. That's the thing with this of how this is spreading in the United States is where does it have a niche that isn't being filled? Right. So it's talking about that the movement southward is not happening as quickly as it is northward, and that's potentially due to more competition in the side.

Ellen: That makes sense. Cause you mentioned that they can withstand the cold better, right?

Christian: There's far fewer spiders that can do that. So they will have less competition in the Northern part of the country. 

Ellen: That makes sense. So y'all can keep them all up there. We're good with what we've got down here. Yeah. We are at spider capacity.

Christian: Oops. All spiders

Ellen: We're overstocked with spiders.

Christian: Passing the savings onto you. (laughter) And I just want to take a little bit of note about the terminology with non-native versus invasive species.

Ellen: Please do.

Christian: So according to the U S National Park Services an invasive species is a quote "non-native species that causes harm to the environment, economy, or human animal or plant health". Whereas non-native species are organisms that do not occur naturally in an area, but are introduced as the result of deliberate or accidental human activities. So all invasive species are non-native, but the opposite is not true. 

Ellen: But not all non-native species are what we would consider invasive. 

Christian: Right. So that might be more nitpicking because you will often see those terms used interchangeably.

Ellen: Especially because I feel like a lot of the coverage of the spider very recently has been intentionally fear-mongering it feels very like, because I know what it's doing, right? It's clickbait. It's trying to get people to open these articles and read because they think, "oh, we're going to tell you about this big, scary, new spider that you need to read this article so that you know about it because you need to be scared of it."

Christian: Right. And to be clear, it is not the research. Like it's not the original research paper that's doing this. It's all the news article, like companies that are picking up and talking about it. 

Ellen: And they're taking that angle of, oh, there's this big, scary spider that could be moving into your neighborhood. Like trying to make you be afraid of it when it's not that big a deal. They're also, I think, throwing around the word invasive a lot when they don't necessarily mean that. And I'm thinking of like the everyday person off the street who doesn't engage with a lot of nature content and maybe has never heard the word invasive when applied to an animal before they might hear the word invasive and think that means this animal is invading your space actively right now. Like they might think this means this is a brand new spider that is actively invading the place where you live. And that's something it's an invader that you need to be afraid of. And I think that a lot of news outlets aren't explaining what that means and just letting people run with it. Right. Because it's something they could hype you up about.

Christian: Because at the end, you know, the, the reader's question is, well, what does that mean for me? The answer is nothing, nothing. Cause right now, you know, it, it doesn't pose any significant risk to individual people and the impact on the environment and the ecology of that area. Good or bad. It's just not. Yeah. Yeah. And I saw a place where, you know, saying, you know, at this time we do not encourage you to kill these spiders on sight. 

Ellen: Please don't do that! Now. I should say, if you're listening to this, you do not have to worry about these spiders. If on the other hand you are a stinkbug, boy, do you have to worry about these spiders. I mean, board up your windows.

Christian: And I know, you know, spiders can be a touchy subject for lots of people, even people who understand, you know, they're not in any real danger, but still experience fear about them. There are products out there that can help you deal with them in a peaceful way. I've seen all sorts of little critter, grabber type things that is like a brush that lets you grab them and then place them outside. Yeah. We'll typically just use a cup or something in a piece of paper. 

Ellen: I have a tried and true strategy when I find a spider in our house, and that is that I find you, and I ask you to get the spider out for me. 

Christian: Yeah. I mean, honestly, being found by one of us is the better option than being found by the cat. 

Ellen: That's true. The cat has no such mercy. All right. You want to talk about invasive species? Let's not. (laughter) That being said, you do not need to kill these spiders. They're not going to hurt you. You probably won't even be able to tell them apart from the spiders we already have here that we've already had for hundreds of years. And haven't really been a big deal at all. 

Christian: Maybe you will now though after listening to this episode. 

Ellen: I don't know if I would trust my ID skills enough to be able to like, give an on the fly differentiation between 

Christian: I'd have to be pretty close, I feel like.

Ellen: And I wouldn't be.

Christian: But yeah, that's the joro spider. 

Ellen: Thank you. I hope we've eased some fears out there. If this spider is keeping you up at night, please rest assured you are fine. You do not have to worry about the spider. 

Christian: Don't call me though. That's only for Ellen. 

Ellen: Rest easy. Hopefully get some, get a good night's sleep tonight. Now that the weight of spider anxiety is off of your shoulders. Thanks, babe.

Christian: No problem. 

Ellen: Let's take a quick moment to hear some promos from our friends on the max fun network. Now we'll get into my animal.

Christian: All right, Ellen, what animal do you have this week? 

Ellen: Sometimes we like set each other up for our animals knowing full well what the other person is about to say, and Christian was over here with nary a thought behind those eyes, completely head empty. No idea what I'm about to say. This is the day octopus.

Christian: Agh. I was guessing worm of some sort.

Ellen: I mean that's not like, the farthest off you could have been. They're also known as the big blue octopus.

Christian: Big blue octopus!

Ellen: Big blue octopus. They're not blue, though. 

Christian: Wait, what was the first common name you said? 

Ellen: Day octopus. 

Christian: D-A-Y? 

Ellen: Yes, like daytime. Uh, scientific name is octopus cyanea.

Both: Octopus is the genus. 

Ellen: Yup. I know, how'd they get that one, right? Like, like how did they, how did they clutch that right.

Christian: The person on Reddit who has the username "user". 

Ellen: It's like they got in really, really early. So they got to like, get their first name as their username. It's like me when my mom signed me up for all of my email addresses when I was like eight and the internet was extremely young and she could still get just my plain name with no numbers attached to it as my email addresses.

Christian: No periods, no nothing.

Ellen: No nothing. Not a number. Not an underscore, just my name. So this is the octopus cyanea and this species was submitted by Kailyn Doss, who is 10 and listens from Alaska.

Christian: Oh wow!

Ellen: I know, right? And sent me just the most delightful email about these octopuses, um, which I'll get into later. It was for a very specific reason that I think you're really gonna like. I'm getting my information from the Marine Bio Conservation Society, the Aquarium of the Pacific and Monterey Bay Aquarium, and also a paper that I'm going to name when it comes up, because there's a huge spoiler in the title, right in the title. 

Christian: As is the way.

Ellen: It just spills all the beans right there. No mystery to it whatsoever.

So this octopus is the body part of it is about six inches long or 16 centimeters. But the arms can be 32 inches long or 80 centimeters. It's pretty big. It's not the biggest octopus, but it's on the bigger side. They're found in the Indo-Pacific region, which includes the Indian and Pacific oceans. So basically from the Eastern coast of Africa, all the way to Hawaii. Pretty big range. You can find them in lots of places. And throughout that range, they like to live in coral reefs or in any sort of area where there's a lot of like rubble, like things that they can nooks and crannies for them to hide in. Yeah, they are in the taxonomic family octopodidae, most known octopus species belong to that family, including the blue ringed which you talked about before. And this one is called the day octopus because it is active in hunting during the day, as opposed to the night where most other octopuses hunt at night, 

Christian: It's DayQuil and NyQuil.q

Ellen: It's the sun and moon version. While we're talking about like octopus taxonomy, an octopus is a type of cephalopod along with squids and cuttlefish.

Uh, cephalopods are mollusks, other things in the mollusk phylum are snails and slugs, and then more distantly related to cephalopods are bivalves. So like clams and oysters. There's other stuff in there too, but those are the mollusks you've probably heard of. So to get into my ratings for the day octopus, for effectiveness, I give it an eight out of 10.

So to talk about effectiveness for the day octopus, we have to take like a quick tour of the octopus body, because it is so different from any sort of vertebrate anatomy, uh, it can be kind of like you look at it and you're like, I don't know where all of your parts are, so they are invertebrates. So no skeleton, no bones.

So their body is really soft and squishy and the body is made up of two kind of sections. The first one is the mantle, which is what we might think of as its head. Um, it's like a big sack basically, or it looks kind of, I think like a water balloon, you know, it's like bulbous and soft, but all of their internal organs are inside of the mantle.

Christian: Right. 

Ellen: So everything that's going on inside their body, is tucked up inside that little floppy sack and then coming out from the mantle, are their eight long limbs. A lot of people call them tentacles, I guess they're technically not tentacles. 

Christian: What?!

Ellen: They're called arms.

Christian: I feel lied to.

Ellen: So yeah, I mean, if this is one of those things, that's like, it really only matters if you want to get super, like, pedantic about it--

Christian: What are true tentacles then?

Ellen: I'm glad you asked, Christian. The difference is in the suction cup. So octopuses have these arms that have suction cups all the way down from the base, all the way to the tip. Tentacles though only have suction cups at the very ends. So imagine like those little sticky hands that you could get at, like Dave and Busters for like 50 tickets, the little gummy sticky hand that you could like stick to windows or the ceiling, and then it gets stuck up there and leave a stain on your ceiling. Yeah, those are tentacles. Squids have tentacles. 

Christian: This is squid propaganda. 

Ellen: This was written by a squid. Um, so octopuses technically don't have tentacles, but I mean, if you call them tentacles, somebody-- people will know what you're talking about. I don't think it's that big a deal, but if you want to be extremely accurate. You could say their arms.

Christian: I will opt to not be. On purpose. 

Ellen: You fight the power, Christian. So having such a soft body free from rigid structures, like bones really gives octopuses a lot of freedom to squeeze through surprisingly tight spaces. Like they could get through an opening that's an inch wide and they're pretty big animals.

Like they're not tiny, but there are, yeah, like the, the giant, uh, what is it? A giant Pacific octopus is enormous and it can still get through like incredibly small openings. I saw like a video that said, I think he was from the Monterey Bay Aquarium that said that a giant Pacific octopus could squeeze through a hole, the size of a quarter.

Christian: I guess I always thought the limiting factor I thought was their beak. 

Ellen: That would be probably the hardest structure on their body.

Christian: Or their eyeballs. 

Ellen: Yeah. Something like that. They're extremely malleable. They can get through tiny, tiny, tiny little spots, which is really important to them in the wild, because it lets them slip into nooks and crannies. Right. Like I mentioned, they live in a coral reef, so they can squeeze in between little crevices and rocks and coral and stuff. And even when they're not squeezing into crevices, day octopuses are actually able to hide in plain sight because they are masters of camouflage. So these are the ones you've probably seen videos of where they'll settle onto a rock or onto a piece of coral or something. And within seconds they have vanished because they just completely become one with the surface they have landed on. So their idle skin color is kind of like a reddish rusty orange, but their skin is covered with these specialized cells, which we've mentioned before called chromatophores. We talked about chromatophores with the veiled chameleon, but the octopus 's work a little differently.

The chameleons were like layered in such a way, but with the octopus, so the cells contain different colors of pigments. In the octopus, they are red, yellow, brown, or black. And it's got this network of these colorful cells all over its body. And the octopus can use its muscles to either expand or contract those cells, which then displays more or less of those colors. So for example, if it wants to turn red, it will just expand all of its red colored cells and shrink all of its non red cells. So what you're left with is just a completely red sort of canvas, but it can do this with remarkable precision. So it doesn't just change its whole body to this color at one time, it actually focuses certain areas to be different colors, to mimic the markings, it can mimic light or shadows. It can move the markings around to like match the flow of the water over its body. It's almost like an invisibility cloak, right. That just like mimics exactly what's going on below. It is so cool. But so lots of octopuses can change their skin color like this, this octopus, the day octopus can actually take that a step further.

They can actually contract their skin in such a way that forms protrusions on their body and change the actual texture of their skin. It's so cool. So they can make their skin bumpy. They can make it jagged, they can make it spiky. Like, they can do some really incredible things to just make their skin look like it's not an octopus. It can be really challenging if you find like a, a video of like a scuba diver coming up on one of these things, it can be really challenging to find the octopus. Lots of great videos of this on YouTube. Challenge yourself to watch one of these videos and find that octopus, it is not easy. But should their hiding and camouflage both fail and they still find themselves threatened they can spit out of cloud of ink. 

Christian: Very good. 

Ellen: Yes. So it startles and disorients their predator and it gives them a chance to escape like a smoke bomb. So something kind of funny about this is that the ink that is produced by the ink sac, it is made up of melanin. So the same pigment found in mammal skin. It's nearly pure melanin. 

Christian: Wow. 

Ellen: Yeah. And it is bound together by mucus. So it's like just a melanin snot mixture that it makes in this ink sack and then kind of spits out through its like siphon. So the thing about that, is that it is literally just melanin and mucus. It's perfectly safe to eat. Yeah. So octopus and squid ink is used as a food additive. It gives color and flavor to all sorts of dishes, including noodles.

Christian: Yeah, noodles is the one I've seen. 

Ellen: Yeah. Have you ever had squid ink noodles? I haven't had it. I've heard it has a very seafoody flavor and I don't like that, but it's supposed to be very tasty. 

Christian: What sauce would I put on it? I don't know. 

Ellen: Well, I was going to say also that the ink sack themselves are even fried and eaten on the Greek island of Kalymnos. Yeah. They just eat the whole thing. When I was a kid one time in like a science class, we dissected a squid and part of the assignment was to find the ink sack and stick a toothpick in it and write our name in the squid ink. It was pretty neat.

Christian: We might have experienced the same curriculum. 

Ellen: We went to school pretty close to each other. So I wouldn't be super surprised. So I did have to give some deductions for the day octopus. So the first one is that I'm thinking about octopus in the context of other mollusks and there's other mollusks out there like snails, nautiluses, which are closely related. They have a shell, like a hard structure to protect their soft body and octopuses don't have that. And I feel like that warrants a deduction because we've seen what the mollusks can do. Defensively. 

Christian: It's a trade-off though, right? Speed for defense. 

Ellen: Yeah, it does grant them dexterity, it grants them agility, and flexibility. Some octopuses like the veined octopus make up for this lack of armor by grabbing on to coconut shells and pulling them around their body to form like a shield. Have you seen this? 

Christian: Yes.

Ellen: It's adorable. They will kind of like pull the coconut shell closed around them and then roll around in them. 

Christian: This is, isn't this also the subject of that sad video where it found like some garbage or something.

Ellen: Yeah, probably. I mean, that sounds like something that probably happens all the time, but yeah, I mean, octopuses do use other objects to protect themselves with. But I just feel like if that armor was just already built into their body, that would just free up their arms to do other cool stuff with it. It was like more crime opportunities. If you have all of your arms free, because you're not holding a coconut shell.

Christian: I don't know if you can run away, you have a chance to do so, but if you are slowed down by a heavy shell and something comes along, that has the strength to get through it, that's it. 

Ellen: But, with the octopus as it is, it requires very little strength to get through the body of an octopus. So I just feel like there's some room for improvement there. And the other thing I, I deduced, uh, a point for is that octopuses, like all octopuses are surprisingly short lived. Um, the longest lived species is the giant Pacific octopus, which only lives around three years. Even the giant squid, which can grow up to 43 feet long, it is absolutely enormous. They only live for about five years. The only like cephalopod that does live for a really long time is the Nautilus. Nautiluses can live for a really long time. The octopuses are here for a good time, not a long time. They're a blip. Usually not around for very long. So the day octopus usually doesn't live for longer than about 15 months. And then during that incredibly short life span, they, like other species of octopus, only reproduce one time and that's it. So they reproduce and then immediately die, like roll credits when condition met, that is the end of the road for them. They reproduce. And then they're like, well, that's it mission accomplished, wrap it up. 

So after a female octopus lays her eggs, she just completely stops eating. She'll stay with the eggs and like protect them, wave water over them, clear them away from debris, kind of like take care of her eggs, but she doesn't eat. And she just eventually starves. And what's interesting about that is that it's kind of thought that this may be something that's built into their brain. And what happens is when they lay their eggs, their brain shuts off their hunger. Like they don't get hungry anymore after that. And this may be in order to keep them from eating their babies because octopuses will not hesitate to eat each other. It is not a big deal. They have no loyalty whatsoever. So it's thought that maybe this keeps her from just eating her babies immediately, if she just doesn't get hungry anymore.

Christian: That's one way to do it. 

Ellen: Right. I mean, it is. I mean, other animals just don't eat their babies. Like there's easier way to do this. 

Christian: Are we in ingenuity yet? 

Ellen: Not yet, but we're about to be. 

Christian: Seems like a good negative there. So not smart enough to not eat your own kids, that you have to be hardwired to cease eating at all.

Ellen: Yeah. It's an all or nothing thing. Like, well, if I'm not going to eat my babies, I guess I won't eat anything at all. I feel like building it into your body to only reproduce once and then die is like quite literally putting all of your eggs in one basket. You know, like you are just rolling your dice and being like, well, hope this is a good batch. Cause that's the only one I'm going to get. You know?

Christian: I guess it's important to know those clutches are very large. 

Ellen: Yeah. They lay lots of eggs at the same time. I mean, probably not that many of them are going to make it to adulthood. They do lay a lot of eggs at a time, but still it's just the one and that's it. That's the only chance you got. Yeah. Hey guys. Welcome to my any percent. No item, no save speed. Run. I'll be playing an octopus like and subscribe to my Twitch. 

Uh, next category for the day octopus is ingenuity. And this is really why we wanted to talk about this octopus. So what octopuses and other cephalopods do have is a really sophisticated, nervous system. Like their whole brain situation is going great, which gives us some really unexpected and cool behaviors. So earlier I mentioned they can change their colors and textures in very targeted ways on their body. They can do this one thing that's a display called a passing cloud, and this is where they pulse dark, bands down their body. And it looks like a passing cloud, like a black cloud that's passing over their body. And this is thought to maybe confused or startled prey. Um, they definitely do it while they're hunting. So it's something that they're doing to disorient their prey in some way, a lot of psychological warfare going on with cephalopods, which we talked about with the cuttlefish. Did you do the cuttlefish or did I do the cuttlefish?

Christian: I think I did. I remember digging into the eyes 

Ellen: That stuff's wild --

Christian: Not literally --

Ellen: I would hope not. That'd be gross. So there are a lot of examples of octopus ingenuity that I could use, but in the interest of time, I'm going to focus on one specifically that Kailyn highlighted. 

So being a predator. Pretty tough job. It can get a little easier when you team up with other predators and engage in something called collaborative hunting. So a famous example here in the USA is tag teams consisting of coyotes and badgers. Did you see that like super viral video, a couple years ago of a coyote and a badger like playing in a storm drain together?

Christian: No. 

Ellen: It was the cutest thing I've ever seen. They were just like goofing off together. It was so cute, but coyotes and badgers team up to hunt squirrels cause coyotes are fast. So they chase the squirrels and then the squirrels go into their burrows and the badgers dig them out. They have overlapping skillsets and can team up to chase squirrels together.

So this happens on the reef. It happens in the ocean. So the day octopus has been known to team up with predatory fish on their reefs, like groupers are a common one that they'll team up with. So the groupers will hunt around and above the reef. And then the octopus chases prey through tight spots in the reef. So the grouper is kind of scaring the prey into the reef where the octopus then is able to squeeze through those nooks and crannies to sort of complete the chase. So there's kind of nowhere safe, right? Like you're swimming around the reef. You're going to get caught by the group or you go into the reef, you get caught by the octopus.

So they kind of have this pretty choice arrangement between them. The thing about this strategy that made headlines recently was the octopuses' way of exerting some control over their hunting partners, their way of making sure that their hunting partners don't take more than what the octopus may consider to be their fair share, because you know, they may be hunting together, but they are still hunting. They're still in it for themselves, you know? So I'm just going to read this quote directly from the paper that it was published in, because it is just like the perfect poetically academic way of describing this behavior. Here we report a series of events dating between the 1st of October, 2018 and the 1st of November, 2018 and the 10th cyanedae May, 2019 and the 10th of July, 2019.

So these are two different one month spans in 2018 and 2019 where different octopus cyanea individuals engage in active displacement of partner fish during collaborative hunting. To this end, the octopus performs a swift explosive motion with one arm directed at a specific fish partner, which we refer to as punching. And that is science for throwing hands. The, and this is from the paper titled, this is why I couldn't tell you this. At the top, the title of the paper is "Octopuses Punch Fishes During Collaborative, Inter Specific Hunting Events." And that is by Eduardo Sempaio, Martin Costa Seco, Ruis Rosa and Simon Gingins. And that was published in Ecology in December of 2020. So really made the rounds in 2021. 

So the paper suggests a few possible motivations behind these punching events. This was apparently a consistent thing. This wasn't just like a, one-off like, oh, the octopus punched a fish one time. We could think like "maybe it was doing something else, and it was an accident". This was like a very intentional, very consistent punch connecting with fish. Yeah, enough times that you're like "this, they're doing it on purpose". So one of the suggested explanations is that the octopus is just moving the fish over to kind of claim dibs on the prey item, you know, just like knocking it out of the way basically. So it could grab, you know, like say there's a, there's one last cookie in the jar and you and your sibling are both running to grab it. And you just like jab them with your elbow to knock them out of the way so you can grab the cookie first. That's kind of the idea.

Christian: But your arm is made of marshmallow.

Ellen: But your arm is made of marshmallow because you're an octopus. But then sometimes the octopus punched the fish, even when it didn't take prey afterwards.

So this is like you and your sibling are just sitting there and you jab them with your elbow for no reason. This was not like for any specific reason. So the paper suggests two possible explanations using concepts from game theory, which is the study of strategy. Um, and this is another quote from the paper:

"Benefits are disregarded entirely by the octopus and punching could be a case of spite. No emotional connotation, used to impose a cost on the fish regardless of self cost. For example, after defections, stealing prey by a usually collaborative partner. So maybe there has been a past instance of that partner stealing prey from the octopus and the octopus punches the fish as an expression of frustration." like, "Hey, I saw that", you know. It's more of a retributional jab, right? The other suggested explanation is that this could basically be a flex to keep the misbehaving partner in line so that maybe like that partner needs a little reminding that the octopus can and will strike at any moment. 

Christian: Awfully toxic for an animal without any venom.

Ellen: It's funny you say that, they do have venom. 

Well, there goes that gold comedy, 

But it's a, it's a mild venom. It's more used for paralyzing prey, but they have a little bit of it. It is toxic though. It is a very toxic environment. They're a horribly manipulative partner. 

Christian: I guess I should have thought about that when we said it was related to the blue ring octopus.

I mean, they're 

Ellen: related in the sense of, they're both like octopuses, they're not closely related. They belong to the same family. So this, I mean, it's interesting because this punching behavior really introduces like a manipulative dynamic to the partnership, unlike most other inter-species collaborations, which are kind of purely, you know, they're sort of acting in their own best interests, parallel to each other. And this one, the octopus is kind of trying to get the other animal to do something and like interacting with it in a way that is trying to make it do something else, which I think is very interesting. I would like to note that in Kailyn's email to me requesting the octopus, this aspect of their behavior was really the driving force of the pitch.

Um, and Kaylin proposed some theories as to why the octopus punches fish, including the fish being annoying and the octopus being a jerk, but also including the fish doing something to the octopus and the octopus holding a grudge, which is not far off. Like that's, I mean, scientists are probably never going to be able to know exactly what's happening in an octopus 's mind when it decides to punch a fish. So we're probably never going to know for sure why they're punching fishes, but Kaylin, your theories are consistent with the research. Like the data is there definitely as valid a theory as any.

Christian: Jealousy over differences in longevity. 

Ellen: Oh, you think maybe the octopus is jealous that the fish gets to live for more than 30 seconds? Yeah, maybe that's it. That's all I really wanted to dive into for ingenuity. There's a billion other things I could say about octopus ingenuity, but we'll save them for future octopus episodes. The final category for the day octopus is aesthetics. I give it an eight out of 10 because we've seen what octopuses can do with their bodies, like, aesthetically with the blue ringed octopus, which is yellow with bright iridescent blue rings. And this one doesn't have those beautiful blue rings, which is kind of a disappointment. Like it's a little bit of a step down aesthetically. I feel like we started off so strong with the blue ringed octopus and then its resting state, it looks like a pretty standard octopus, you know, but it's also, I feel like it's hard to know what they really look like because they're always changing their appearance to camouflage themselves. So like, it was really difficult for me to find like pictures or videos of them just in their relaxed, natural state when they weren't actively camouflaging themselves. I mean, I find octopuses very cute. I like that they have those big round eyes that are really close together that really has sort of a cartoonish effect. And then that big bulbous, like water balloon head, I don't know, they look so goofy, but in a really charming way, I think they're cute, that's why I gave them an eight.

Yeah, to wrap things up for the day octopus they're of least concern as far as conservation goes. So their populations do seem to be stable, but that being said, they depend pretty much exclusively on coral reefs. So, because they are so intricately linked with coral reefs, they are vulnerable to climate change because reefs are vulnerable to climate change. So if the reefs go, the octopuses will then also go and reefs are going through a lot right now with climate change, affecting the oceans in a lot of big ways. So. If you love these octopuses and find them as delightfully fascinating as I do, only action items I could really tell people to do would be to look into ways that you can help support your ocean. If you live near a coral reef, maybe you see if there are some local action items for protecting your local reefs, just, you know, look out for our ocean because that's where the cool octopuses live. 

And that is the day octopus. Thank you. 

Christian: Good octopus.

Ellen: It's a great octopus. Thank you Kailyn for bringing this to my desk.

Well, thank you to everybody who has listened today. I hope that you enjoyed it. I know we did. It's always nice to talk to you, Christian.

Christian: Likewise.

Ellen: Uh, if you liked what you heard today, it would really mean a lot to us if you could leave us a good review. I hope that we have earned five stars from you also right now on Podchaser, they're doing a fundraiser throughout the month of April, where for every review that is left on podcasts or episodes, you can review like individual episodes on Podchaser, so for every review that's left and then reply, which I can reply to reviews on Podchaser was I think is cool. They make donations to support charities. I believe this one goes to feeding refugees from Ukraine. So it's a, it's a great cause. Uh, so if you feel like doing that hop over to Podchaser and leave us a review and we'll reply to it to double your donation.

You can also connect with us on social media. We're on Facebook, Twitter, Instagram, Discord. You can also shoot me an email. My email address is ellen@justthezooofus.com. That is, by the way, the best way to get ahold of me, you know, social media can get a little hectic sometimes. So if you have an animal you want to hear us talk about or something, if it's something that requires my attention, please do email that to me. 

Christian: Why's our social media so hectic right now, Ellen?

Ellen: I don't know. Christian. Why is it ?

Christian: Causing problems? 

Ellen: I am. I've been a menace on Twitter recently. Sorry. 

Christian: Also related to octopus.

Ellen: It was related to octopus. I, kind of my notes for this sort of prompted that. So, uh, we'd like to wrap up by saying that you could have Maximum Fun for having us on their network, alongside their other, just delightful shows, like the ones that you have heard promos for here today.

I'm going to be specific with my Maximum Fun shout outs. This week, I've been listening to Depresh Mode with John Moe a lot recently, it's a really nice show. I really like it. So if you're looking for a new show to add to your lineup, I really like Depresh Mode. I'm going to start trying to be specific with my Maximum Fun shout outs at the end.

Yeah. While you're over there at maximumfun.org, we would love it if you signed up for a membership to keep us going alongside the other shows on the network. And finally thank you to Louie Zong for our incredible theme music, which we love so dearly. 

Christian: It is so good.

Ellen: And that's all for today. Next week's episode is about PANGOLIIIINS.

Christian: Bye.

Ellen: See ya!

Christian: Bye.

Ellen: Byeeeee.

34: Anglerfish & Desert Kangaroo Rat

Ellen: Hi everybody! This is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And we're here with Just the Zoo of Us, your favorite animal review podcast.

Christian: Each animal on the show, we review and rate on a, out of 10 basis in three different categories of effectiveness, ingenuity and aesthetics.

Ellen: That's right. And even though Christian and I are not experts on animals, we do a lot of research for the show to make sure that we're giving you really good information from good sources.

Christian: You know what we are experts on?

Ellen: Oreos.

Christian: Dunking. That's weird. We had a motif. All right. Have any announcements before we jump in?

Ellen: Um, yeah. So if you remember back in December for Giving Tuesday, we gave our ad revenue to the Wildlife Conservation Network. We decided to again donate our ad revenue since that donation to the New South Wales Rural Fire Service in response to the bushfires going on in Australia. So we would really encourage everybody listening to look into ways that you can support the efforts to relieve Australia during these difficult times.

Christian: So this week I'm bringing our first ever social media poll-elected animal.

Ellen: This was our first democratically, democratically chosen animal.

Christian: Now that I think about it, I forgot to vote. Was I not supposed to vote?

Ellen: I don't think you were supposed to vote, no.

Christian: Okay. And that animal for this week is the humpback anglerfish, scientific name Melanocetus johnsonii.

Ellen: Nice.

Christian: Also known as the deep sea anglerfish. So like I said, this was chosen by our social media poll. Prior to that it was also submitted by Michael Solon, Kyle Rauch, Abigail Cornett, and @squirrelbeer23.

Ellen: Nice.

Christian: I'm getting my information for this animal from fishbase.se and oceana.org. Basic info on this species: their adult size, the males are about 2.9 centimeters long, that's about 1.1 inches, whereas the females are 18 centimeters long, or 7.1 inches.

Ellen: That is a huge difference!

Christian: Yes. So the females are about six times larger than males.

Ellen: That is some serious dimorphism.

Christian: Yep, and this is a common thing amongst all the anglerfish species where the females are much, much larger.

Ellen: Girl power.

Christian: Yeah. They can be found in the, what is known as the bathopelagic zone of the oceans. And this is the zone that is the depth of 1,000 to 4,000 meters deep. And those are in the tropical and temperate parts of the world's oceans. So they can be found pretty much all over the world. They're pretty much in all the world's oceans except for the very extreme cold areas near the poles, basically.

Ellen: Sure, sure sure.

Christian: But they're usually found at a depth of a hundred to 1,500 meters, or about 300 to 5,000 feet.

Ellen: Okay. So they're way down there.

Christian: They can be, yes. They belong to the taxonomic family Melanocetidae, or known as the black seadevils.

Ellen: That's a very intimidating name.

Christian: Yes. If you see a picture of these things, a lot of the times they're sleek black. I had a hard time trying to find out what they look like in the wild versus what they might look like in a specimen jar.

Ellen: That's true, cause with those deep sea critters there can be a big difference.

Christian: Yeah. But I'm pretty sure if caught wild they are like, a sleek black.

Ellen: Okay. I feel like black seadevil sounds like something that you would hear in a pirate movie, where like some old haggard seadevil- like, this old haggard sea pirate is like telling a story about, "we once came across the black seadevil," like doesn't that sound like something legendary and mythical?

Christian: Sure, but I'm going to need a smaller boat, cause these are little. Even you know, the females that are much larger, you're still only talking about like a foot and a half there.

Ellen: That's true. I guess they're not going to be taking down your ship anytime soon.

Christian: Speaking of taxonomic family, other evolutionary relatives are pretty much all anglerfish that belong to the Lophiiformes order. So I think a lot of our submissions were just the anglerfish in general.

Ellen: Yep.

Christian: The word "anglerfish" refers to an entire order, so this one is a specific species. Other members of their family include the Murray's abyssal anglerfish.

Ellen: Abyssal anglerfish.

Christian: Yes. It sounds like something right out of RuneScape.

Ellen: I love the word abyssal. It's so dramatic.

Christian: It is, and something like that to talk about that I hopefully will keep doing with my animals is the etymology of their names.

Ellen: Ooh, yes! I would like that.

Christian: Which I think I mispronounced that last time. I think I said entomology, which is something else.

Ellen: I think you did. Yeah, it's the study of like bugs, insects and stuff. But it's okay. I'm sure people got what you meant.

Christian: So talking about its scientific name, this species: Melanocetus comes from Greek. The melos- or, "melanos" means black and then "cetos" is a large sea creature, usually referring to a whale.

Ellen: Oh, like a cetacean.

Christian: Right.

Ellen: And I'm also seeing the same root as melanin.

Christian: Yes. Johnsonii comes- is just named after the last name of the first person that found it.

Ellen: Boring!

Christian: Whose last name was Johnson.

Ellen: BORING!

Christian: Yeah.

Ellen: Name it better.

Christian: That's a common one where part of the name is dedicated to the person that found it.

Ellen: Yeah, and it's a let down every single time.

Christian: Sure, sure, sure. So, I'm going to jump right in. Our first category is effectiveness. These are biological and anatomical adaptations to make it do well in its environment, or the things they tried to do.

Ellen: Good body stuff.

Christian: Yeah. I'm going to give the humpback anglerfish an 8 out of 10 for effectiveness.

Ellen: That's pretty good. It's decent.

Christian: So let's keep in mind this fish is found very deep and very low, if any light, and pretty sparse populated prey options there. So my first category, or I should say my first point for effectiveness I'm giving it is bioluminescence. So this is something that many anglerfish are known for. So this species of anglerfish has what one would call a lure. That's a little dangly bit that sits on its forehead, I guess you would call it. And that's also known as an esca, or illicium.

Ellen: Oh. I didn't know they were cool words for it.

Christian: Yeah.

Ellen: This is like in Finding Nemo.

Christian: Yeah. Well... Was that in Finding Nemo or Finding Dory?

Ellen: No, it was Finding Nemo, it was in in the first one I remember because it scared me very badly.

Christian: Yes, yes, yes. So that little lure has bacteria inside it and it reacts with the body of the fish to produce light.

Ellen: Oh, it's caused by a bacteria in there?

Christian: Yeah.

Ellen: Interesting. Does that bacteria grow there naturally or does the fish put it there?

Christian: You know, there's been a couple of thoughts on how it gets there. One thought is that the young get it from their parents in some way, because they've noticed among different species of anglerfish that species of bacteria is different.

Ellen: Oh!

Christian: Yeah. So there's, there's some thought around how they get it.

Ellen: They're like, cultivating their own special brand of glowy bits.

Christian: Something like that. And a lot of times they've noticed that the bacteria, when taken out of the fish, on their own cannot produce light. So it has to be interacting with the fish itself to do it.

Ellen: Whoa. That's very complicated.

Christian: Yeah. Yeah. So I'll talk more about what it uses this for later in my ingenuity area.

Ellen: Sure.

Christian: But just a note, only the females of this species have the lighted lure.

Ellen: Let's go girls.

Christian: My next point here is what I'm naming their big appetite. So first, let's talk about what these guys look like. This particular anglerfish has a mouth that is very large, and also looks like someone took it and rotated it upwards about 45 degrees.

Ellen: Oh, it's like... It's like angled upward?

Christian: Yeah. And this is a common trait among anglerfish too, is this style of mouth.

Ellen: So it always kind of looks like they're looking up a little bit.

Christian: Yeah. But yeah, this big, big mouth, long pointy teeth, which would imply they're trying to grab slippery prey, like other fish.

Ellen: Sure.

Christian: And their jaw and stomach can extend and allows to eat things that are bigger than they are.

Ellen: Ex... Extend? Like within- still inside the fish?

Christian: Yes. Yeah.

Ellen: Okay. You know, you never know with those deep sea critters, some of them just like expand their entire gut content, like out of their body or do some weird stuff.

Christian: So, so it comes from the scarcity of food in this area. So it wants to increase its chances of being able to actually eat something that it finds.

Ellen: Oh yeah.

Christian: Yeah.

Ellen: Cause you never know, like you gotta take what you can get. Right? It might be another six months before you come across some other living creature.

Christian: Right, right. So yeah, a lot of times they'll be found with something in its stomach that is bigger than they are.

Ellen: Oh my gosh.

Christian: And my final point for effectiveness is reproduction. So the males have special senses that allow them to find the females. It's thought to be pheromone-based because again, because of how sparse this species is that this depth, pretty much the male's main objective is to find females. That's it.

Ellen: He's a carrier for genetic data. And also there is no light where they live. Right?

Christian: Right. In the deeper part of that area, there's no light.

Ellen: So they can't exactly seek each other out.

Christian: In some species of anglerfish, the males will have big eyes and then others, they have anatomy that would suggest they're relying on smell.

Ellen: Oh.

Christian: So regardless, it seems to be the common theme among the anglerfish species is that the males have something to assist them in finding the females.

Ellen: Sure.

Christian: So something that is common among many anglerfish is this idea that males will latch on to the female and then will basically fuse into their body. And pretty much all they're there for is to... Hmmm.

Ellen: Is to what, Christian?

Christian: Trying to think how to word this for our rating.

Ellen: Deposit genetic information.

Christian: Yeah. They're basically just there to do that and that's it. Cause then they're getting nutrients from their hosts. This is kind of known as a parasitic type relationship. In this species, that is not the case.

Ellen: Oh! They've gone to couples therapy and they've learned better healthy relationship strategies.

Christian: Oddly enough, they'll still latch on, but they're doing an external fertilization of eggs.

Ellen: Okay.

Christian: And then when they're done with that, they release and go on to find another.

Ellen: Oh, so that's actually pretty good. Right? That's better. I think that's an improvement from other types of anglerfish where the male just latches on and dies.

Christian: Well, they don't die, they just fuse into them. And I mean, one could talk about what constitutes separate fish in that scenario, but that's more for the philosophers.

Ellen: What if the female just is like a Katamari where she's just swimming around and just collecting all of these male anglerfish and getting bigger and bigger and bigger.

Christian: Well, they don't get bigger. They just have little nodules that represent where the male was.

Ellen: Crafting an armor out of the corpses of her dead lovers.

Christian: So if our listeners want to go see this, I suggest it because it's not very cute, particularly.

Ellen: No. I wasn't thinking that it would be.

Christian: But anyway, so yeah, that that wraps up effectiveness. I'll move on to ingenuity. So this is where they're doing smart things. Could be hunting methods, could be tool use, that sort of thing. I'm giving the humpback anglerfish a 6 out of 10 for ingenuity.

Ellen: It's okay.

Christian: My first point is being an ambush predator. So again, going back to the scarcity of food, one of its goals is to conserve energy. So it's a sit and wait type of predator. So, earlier I mentioned it has a bioluminescent lure. So basically what it's doing there is it's using its lure to lure in prey, and it'll do this by kind of wiggling that lure to make it look like, I don't know, a smaller prey that it's prey would be interested in. And then once that thing is close enough to them, that's when they'll spring into action and gobbling them up. But other than that moment, they're usually not moving very much. Just kind of floating along, conserving energy.

Ellen: Stealthy. Stealthy and smart.

Christian: Yeah. Yeah.

Ellen: But I like how they like, wiggle the lure to be enticing to their prey. I think that is a little bit clever.

Christian: Yeah. Yeah. That's why I figured it should go into this category.

Ellen: Yeah, that's smart. Cause they're kind of using their body as a tool.

Christian: Yeah. And then, somewhat related. The way I worded it is "alluring" behavior...

Ellen: Oh my God, I should have known.

Christian: Because they also use this to attract mates.

Ellen: I should have known you were going to do this.

Christian: So in the same way that they're using it to attract prey, they'll also attract their mates for reproductive purposes, of course.

Ellen: Are the males attracted by larger lures in the females?

Christian: Who knows?

Ellen: I would really love to know the anglerfish's standards of beauty.

Christian: I mean, so they're already going to a female that is six times their size. So I'm wondering if they could even tell the difference at that scale.

Ellen: She's just a monolith either way.

Christian: Yeah. Yeah. They big. And then the final category, aesthetics. Pretty self explanatory. How cute they are. This species is not cute.

Ellen: No, it's none.

Christian: But I still give it a 4.

Ellen: What! You've been too kind to this fish! This is like the go-to ugly fish.

Christian: Yeah, it's a thing of nightmares a little bit. It doesn't have scales. Its skin is kinda smooth. It has these big teeth and a big mouth in it and a teeny squish like, eye area of its head. Its tail is not very impressive at all. It's- cause it goes like, big head and then the rest of its body kind of tapers into smaller, smaller, smaller.

Ellen: It's mostly mouth.

Christian: Yeah. Mostly mouth and stomach when it, when it eats something,

Ellen: You're not really making the case for any of the points that you gave it.

Christian: It's also like, sleek and black. It's kind of like Batman fish.

Ellen: Is it? Is it though? I don't think Batman would be caught dead with this fish. I don't think this fish is going to go on Batman's utility belt.

Christian: Could you imagine? Go! Bat anglerfish!

Ellen: And all it does is it just has a little light on it and he just uses it as like a little light source. They're like, "Batman, there was a much easier way for you to do this. You can just get a flashlight."

Christian: I think they look a little intimidating and cool a little bit, so that's why I gave it a 4.

Ellen: Okay. I guess. I GUESS.

Christian: And now, I know what's going to come up. I think people will compare this to the goblin shark, but it doesn't do the weird mouth extendo thing that...

Ellen: That was what I was imagining when you said that it's stomach expands. Like I was imagining that it like, *bleh*, like it shoots its stomach out of his mouth. I don't know why I thought that.

Christian: No, no no. It's just, its belly gets really, really big basically.

Ellen: Oh, cute.

Christian: Yeah.

Ellen: That's true. I can't really pick which one I find more unsettling, the anglerfish or the goblin shark, because they both have the creepy needle teeth. I don't know which one I prefer. They're both gross.

Christian: It's very unlikely we'll ever see one in person.

Ellen: That's true. And we have that to be thankful for.

Christian: Move on to a little bit of miscellaneous info, mostly around conservation. This species is at least concern on the IUCN list. So while they are rare to find because of how spread out they are and where they are, it's thought they're not threatened at all. Things that would threaten them would be pretty much anything that affects the deep ocean, pollution and such. And that wraps up the humpback anglerfish.

Ellen: Good feesh.

Christian: Yeah.

Ellen: Good job babe. This is a weird one, I think. I think that the anglerfish is what people usually immediately think of when they think of a deep sea fish. I think this is kind of the poster child for deep sea fish in general.

Christian: For sure. It's popular in visual media, I think. And also this was another species that the Oatmeal did a good, good deal of stuff on.

Ellen: Oh did they really?

Christian: Yeah. Well I don't know about this species in particular, but just anglerfish in general.

Ellen: Yeah, I think there's a lot to say about them. They're pretty cool. And I do, whenever I think of one, I do think of Finding Nemo when one scared me very badly.

Christian: Yeah. Yeah.

Ellen: I'm already given the heebie-jeebies by fish in general and deep sea fish especially so, but Finding Nemo was a little bit more traumatic than people like to admit that it was. Right? Cause it opens with a very brutal and harsh... Rough scene.

Christian: I mean it kinda gave justice to how rough life in the ocean can be.

Ellen: Yeah. It was brutally honest about that. So it starts off pretty rough and it gets worse from there. But the anglerfish scene from Finding Nemo was like when I- when I was a little kid and I had the Finding Nemo like, DVD, you remember how on DVDs you would be able to like, skip scenes...

Christian: Sure.

Ellen: ...With a button on your remote? I would skip the anglerfish scene every time. I was like, no thanks. I don't think I'll be doing that.

Christian: That's funny.

Ellen: Yeah.

Christian: That's it for the little... Little light nightmare.

Ellen: A lightmare. No. Does that work?

Christian: No. I'm just going to give up. So, what animal do you have for us this week, my love?

Ellen: This week I'm going to be talking about the desert kangaroo rat.

Christian: Interesting.

Ellen: Yeah. The scientific name is Dipodomys deserti, and this species was not elected via poll, but it was requested, and it was submitted via Twitter by this artist that I follow that goes by the handle Thornwolf at the handle @ThornwolfArt. And you can find some really beautiful illustrations there of a lot of animals. But Thornwolf uses a kangaroo rat as the profile picture.

Christian: Ooh!

Ellen: Yeah. So you could see a really cool drawing of the kangaroo rat. It's very beautiful. So thank you for submitting this animal. This was really cool. And I'm getting my information on the desert kangaroo rat from the University of Michigan's Animal Diversity Web, the United States National Park Service, and the Arizona Sonora Desert Museum.

Christian: Very good.

Ellen: Yes. That should give you a little bit of an idea of where this animal lives. So, if you don't know anything about the desert kangaroo rat, they are about the size of a mouse. So the total length is around a foot long, but half of that is tail. So they're mostly tail but have a little mouse-sized body. They look very similar to a gerbil.

Christian: Okay.

Ellen: And some notable features of it are it has a large ratio of head to body. Like I feel like they have a really big head and then a little tiny little body and they have really, really long hind legs that they actually hop on bipedally. So they don't crawl around on all fours like some other rodents do. They're actually bipedal, so they hop around on these two back legs that are very, very long. So this is where they get the name kangaroo rat.

Christian: Okay.

Ellen: They have those long back feet, like a kangaroo.

Christian: I think I've seen a picture of this, but I'm not sure.

Ellen: You can find these in the Southwestern United States, including the Mojave desert, the Sonoran desert and even Death Valley, which is known as one of the hottest places on Earth.

Christian: Awesome.

Ellen: It's a very hostile environment. They are from the taxonomic family Heteromyidae, which is a rodent family made up of 60 species of kangaroo rats and pocket mice. So although their appearance is very similar to gerbils, they're actually more closely related to gophers. So this is an example of convergent evolution with gerbils, where they're not actually very closely related, but they evolved some very similar features because they both evolved in desert conditions. So gerbils are from the other side of the world. They're from Northern Africa, the middle East, and some parts of Asia, and kangaroo rats are from America.

Christian: Interesting.

Ellen: It's an interesting example of convergent evolution. They're not necessarily closely related, but have some similar features. To get into my effectiveness rating for the kangaroo rat, I give the kangaroo rat a 10 out of 10.

Christian: Really!

Ellen: Yes!

Christian: Alright.

Christian: So I want you to think back to the Arabian camel episode and how I gave the Arabian camel a 10 out of 10 for being so specifically well-adapted to living where it lives. This is the same concept. So I gave them a 10 for how incredibly well-suited they are to live in a very unfriendly environment. Right?

Christian: Yeah.

Ellen: So first point for their effectiveness is what I'm considering their fuel efficiency. Yes. So kangaroo rats not only almost never need water, almost never, but their diet is mostly just dry seeds. So a lot of times with animals that live in these deserts, they'll get moisture from eating maybe succulent plants or some sort of live plant that stores moisture in it. Not the kangaroo rat. They eat seeds, which are mostly pretty dry.

Christian: Yeah.

Ellen: So that makes you think, how do they survive with such a moisture deficient diet? And to understand this, you have to zoom in on their kidneys. Yes. So the kidneys in your body are essentially your body's filtration system that filters blood before sending it back to the heart, and also passes waste through to capture water and nutrients out of the fluids in your body, and then excrete the rest as waste into your urine. So, the kidneys are made up of about a million of these structural units called nephrons. And then the nephrons are these really complicated systems of tubules. I'm not going to go too far into the structure of nephrons and kidneys, but what is important is one of these sections of tubules called the loop of Henle, which is a really, really narrow U-shaped tubule. And the purpose of this loop is to reabsorb water and salt from fluids in the body, which makes the urine more concentrated.

Christian: Yeah.

Ellen: So the kangaroo rat has a really, really insanely long loop of Henle, way longer than in humans or other animals.

Christian: So this structure is common among animals that have kidneys?

Ellen: Yeah, like we have it.

Christian: Okay.

Ellen: Yeah. It's not exclusive to the species. It's just in this species, it is much longer than it is in other species.

Christian: Okay.

Ellen: And what this means is that fluids that pass through the kidneys have a lot more water squeezed out of it. So there's more opportunity for water and nutrients to be metabolized out of fluids that are passing through the kidneys, which means that their urine gets extremely concentrated. It's like, almost solid. Yeah. So what this is letting them do is they're metabolizing the nutrients from the seeds into water and then they end up producing only a couple of drops of highly concentrated urine per day.

Christian: Huh.

Ellen: Yeah. So they are just squeezing every tiny little bit of water they can get out of their diet.

Christian: I guess their body's just really, really good at recycling water to where it's, it's not losing very much, so it doesn't need to take in very much.

Ellen: Yeah. So another thing that lets them conserve water in their body is that they have these really narrow nasal passages, and this traps water in the air that they're exhaling and lets them reabsorb it back into the body.

Christian: Oh, okay.

Ellen: So since they do eat those dry seeds, they can stash the seeds that they eat in cheek pouches. Yes. But unlike in other rodents like hamsters and squirrels, which just shove the food inside of their mouth and store them inside the mouth, these cheek pouches are external.

Christian: Whoa.

Ellen: Yeah. So... This took like a long time for me to really understand how these cheek pouches work. So the openings of the pouches are kind of like flaps of skin over the sides of the mouth, and the inside of the cheek pouches extend all the way to the back of the shoulders.

Christian: That's insane.

Ellen: Yes. So since these are external and they're not actually inside of the mouth, the pouches are lined with fur just like the rest of the skin on the body.

Ellen: It's very weird. Look up a picture of it. It's so weird. It's very creepy looking. These external cheek pouches let them carry around lots and lots of seeds without needing to make frequent trips back to their burrow to stash. Yeah. This is actually a difference. Gerbils don't have cheek pouches, but kangaroo rats do.

Christian: Interesting.

Ellen: Yeah. I gave them major effectiveness points, not just for survival from the elements, but also for having some pretty good predator evasion mechanics. So, uh, the first one being a big hop. So they have those big long hind legs. With those hind legs, they can jump up to nine feet, or 2.75 meters, in one jump.

Christian: That's... Really far.

Ellen: It's so far. That's, you know, I said like nine times the length of their entire body.

Christian: Bye bye.

Ellen: Goodbye! Boinggg! And they're very, very quick and they use their long tail as a counterbalance to keep them balanced when they're jumping around so they're not like, tumbling all over the place.

Christian: Sure.

Ellen: So, and their hind legs aren't just for mobility. So you can find a video online of a desert kangaroo rat escaping the strike of a rattlesnake by quickly twisting its body around and kicking the snake right in the teeth.

Christian: That's not where you want to kick it.

Ellen: Kicks him in the face! Just punts the snake and the snake drops the rat and the rat scurries away.

Christian: Bye!

Christian: It says goodbyeeee! I will not be eaten today.

Christian: So, now I'm seeing where the kangaroo moniker comes from.

Ellen: Yeah. They are not afraid to kick you square in the jaw and both literally and figuratively bounce. So also, when they're making aggressive displays at each other, they will stomp their feet on the ground and it makes it a little like, *thunk thunk thunk* sound.

Christian: Mad!

Ellen: Yeah! They pout and stomp their feet on the ground and it's cute to us. But to other kangaroo rats or even to potential predators it's a more aggressive display. So, sometimes it works. I saw a video that was Sir David Attenborough watching this kangaroo rat that was being harassed by a snake, and you see the little rat getting all mad and he stomped his little feet. So the kangaroo rat also has these huge ears, and the ears are really, really sensitive so it has really good hearing, and it can even hear owls approaching. And owls are known for being very silent flyers.

Christian: Right.

Ellen: So that's my 10 out of 10. I figured they had it all, right? They have good survival, good predator evasion. They're just, they're pretty well suited to doing what they're doing.

Christian: Yeah, for sure.

Ellen: This brings me to ingenuity for the desert kangaroo rat. I'm giving them an 8 out of 10. They're pretty clever. So kangaroo rats live in underground burrows that can have complex tunnel systems, but they do live by themselves. So there's not any sort of like... I dunno, colony structure, like there's no socialization. It's just the one, the one kangaroo rat. Other than when a female has babies and the babies will live in her burrow with her, but other than that it's just one. So when kangaroo rats have foraged extra seeds, they will stash the surplus in their underground burrow. And this actually, when the seeds are in storage underground, they're absorbing more moisture from the ground. This gives the kangaroo rat more water when they eat them. So I thought it was interesting. They're almost like cultivating their food to make it better for them.

Christian: Yeah.

Ellen: It's pretty neat. I thought that was pretty clever. And they will sometimes use sand as a tool. They hide their seeds by covering them up with sand. They will also kick sand over the entrances to their burrows to hide it from intruders, and when they encounter something unfamiliar, they kick sand at it.

Christian: What's that? Sh-sha!

Ellen: What they're kind of doing is they're testing it for a response. So trying to see if it's alive or not and if it's something they need to be worried about. But yeah, they will just kick sand at it.

Christian: So this is their version of "poke it with a stick"

Ellen: But they don't have a stick nearby, so just poke it with a bunch of sand. I consider that kind of a ranged attack almost, because you just kick sand at it. And this actually can be a defensive technique, so it could intimidate or even just annoy predators enough to get them to leave. So in that video I was talking about with David Attenborough where there's a kangaroo rat, the kangaroo rat escapes the snake by kicking sand at it and the snake just gets annoyed and leaves.

Christian: Snake's accuracy is lowered!

Ellen: Wild snake fled. It's like the snake is just like, "Oh gosh, I hate this," and it just turns and runs away. It's not worth it. So they also use the sand to keep their fur clean by rolling around in it, taking dust baths, which is adorable. It's really cute.

Christian: Kinda like the chinchilla?

Ellen: Yes. A lot like a chinchilla. And kangaroo rat moms will kick sand onto their babies to dry them off after they're born.

Christian: Oh, I thought it was a discipline thing, like, "Y'all be quiet."

Ellen: I'm sure they would if they were bothering her. Listen, they live on sand dunes, right? When sand is literally all you have around you, you're going to use it for everything. Right?

Christian: Tell that to Anakin Skywalker.

Ellen: So that's my 8 out of 10 for their ingenuity for the desert kangaroo rat, and that brings me to aesthetics. For aesthetics I also gave them an 8 out of 10.

Christian: Okay.

Ellen: They're very cute. They have cute big round eyes because they're nocturnal, and being a functional nocturnal animal, not like the koala that has a little tiny beady eyes, they have these big round eyes that let a lot of light in. They have pleasant sandy blonde colored fur, it's like a light.... It's the color of sand. Right? But it also has patches of white. I think it looks kind of like a dreamsicle color palette. Yeah, it's really cute. They also have that long, tufted tail and the long bunny rabbit legs and then they got big old chonky cheeks, which I'm really into. It's really cute.

Christian: Do you think they store sand in those pouches sometimes?.

Ellen: I don't see why they would.

Christian: Pocket sand.

Ellen: I doubt that they would do that. Oh yeah, because, you know, just in case they run out of sand. In case they're experiencing a shortage of sand and there's just not enough and they need more. No, I don't think they'd do that.

Christian: Okay.

Ellen: But yes, this is a cute friend. So I gave them an 8 out of 10 for aesthetics. So for miscellaneous information for the desert kangaroo rat, their conservation status is of least concern.

Christian: Good for them.

Ellen: They're doing pretty good. The kangaroo rats prefer to live in sandy dunes with little vegetation. So they're actually pretty hardy. They're not really bothered by, say there's like agricultural activity going on somewhere and the soil gets overturned or something. They're not bothered by that. They can still work with that.

Christian: Okay.

Ellen: Yeah. So they're pretty hardy. They're adaptable. Yeah. So their biggest known non-natural threat is actually just vehicle activity. They get hit by cars sometimes.

Christian: That makes sense.

Ellen: But not anything that's really a huge threat to their numbers. Just sometimes they get hit by cars. So I guess the best thing you can do for the kangaroo rat is keep your eyes out and drive carefully when driving through the desert.

Christian: I guess that kind of desert habitat would be least prone to being affected by invasive species.

Ellen: What kind of invasive species? I imagine a reptile would be having a field day out there, but... I can think of one invasive species that would not thrive in the Mojave desert.

Christian: What's that?

Ellen: The red lionfish! It's the only way they can be stopped.

Christian: We'll do the Patrick method where we could just take the lion fish out of the ocean...

Ellen: We'll put them in the desert where they can't- listen. There's no coral reefs for them to destroy out there. It's the only place that's safe.

Christian: Oh no, they developed legs and lungs!

Ellen: Oh no! This is evolution all over again. It's happening live. Well, that's it.

Christian: Thanks honey. It's a very interesting animal.

Ellen: I thought so too. I thought it was really cool. I love desert animals. It's such an unforgiving type of habitat, and seeing the way the animals evolve to thrive there is always really interesting. There's always something cool going on in the desert. And I was a little bit inspired to talk about a desert animal because our friend Julie, who lives in Phoenix, Arizona in the middle of a desert, visited us recently and gave my five-year-old a book titled, Guess Who's in the Desert? And it's all about animals that live in the desert. I don't think the kangaroo rat was in there specifically, but it definitely did have me thinking about, I had desert animals on the brain.

Christian: Did it list the aliens?

Ellen: You know what? It didn't because I bet if it did list the aliens in area 51, then the books would have all been pulled by the government because they don't want us to know about the aliens in area 51.

Christian: You know what I think of when I think of animals, or desert animals, is that movie Rango.

Ellen: Oh, I love that movie!

Christian: Yeah. Now we were talking about animals that would not do well if dropped into a desert. I think a chameleon would be one of them.

Ellen: You know, what drives me crazy is that Rango very much looks like a chameleon, and I think at some point in the movie he like, changes color to imply that he would be a chameleon. And a chameleon would pretty much instantly die. Right?

Christian: Well when he, when he's introduced to it, he does like a shrivel up and, like shed type thing.

Ellen: Yeah.

Christian: Oh, hot take. Hot take.

Ellen: Yeah.

Christian: That point in the movie forward is not real, cause he died.

Ellen: Mmmm. Okay. The worst type of fiction theory, the whole "main character was dead/asleep/in a coma all along" theory.

Christian: I'll take my check now.

Ellen: Okay. I think that's as off-topic as I'm okay with getting in this episode.

Christian: Okay!

Ellen: We're still talking about desert animals, so I guess we're okay. We're within bounds.

Christian: Yeah.

Ellen: Well that's it for us this week, so thank you so much for spending this time with us. We have made a lot of new friends, a lot of new people are joining the Just the Zoo of Us family and that's really exciting for us, so we really appreciate that and we would really love it if you could come hang out with us on social media. We're on Facebook, Twitter, and Instagram. Come join our group and follow us on Twitter cause that's where the polls are going, where you can vote on what animal we talk about every week. If you have a species that you want to hear, you can submit those to us either on social media or at my email address, which is ellen@justthezooofus.com. A transcript of this episode and all of those proceeding it can be found at www.justthezooofus.com and to wrap up, we would like to thank Louie Zong for allowing us to use his song "Adventuring" from his album Bee Sides.

Christian: Yes, thank you so much!

Ellen: And thank you to you all who've been listening. We love you.

Christian: *kiss*

Ellen: Well now I'm jealous.

Christian: Bye!

Ellen: Byeeee!


33: Luna Moth & Koala

Ellen: Hey everyone, it's Ellen Weatherford!

Christian: And Christian Weatherford.

Ellen: And we're back with Just the Zoo of Us, your favorite animal review podcast where we take your favorite species of animals and we review them and rate them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: We, the inhabitants of 2019, are not zoological experts.

Ellen: We still will not be in 2020. At the time of this recording, it's still 2019, but by the time this episode goes out it will be 2020, and I don't anticipate either of us suddenly becoming zoological experts in the next... 48 hours.

Christian: But regardless, hello, future people of 2020. This is 2019 Christian.

Ellen: And you know, it's been a minute since we've been in the saddle recording a new episode. It's been a few weeks. We had some time off. Though lots of new people have joined us. We have a lot of new people listening so that's really exciting.

Christian: I have forgotten how to record. I tried to eat the microphone, that's not how it works.

Ellen: We're recording live from inside Christian's intestines. I just wanted to mention that when we went on our little holiday break, we put a little survey out there asking people what they thought for their feedback and for things that they thought we should modify or change. And we had some, a lot of really great suggestions that we really took to heart and one of those was incorporating a voting system into our species requests. So if you've been listening for a while, you know that normally we just kind of take requests, and people let us know what they want to hear and and we kind of fit them into our schedule where we feel it's right. But what we're going to start doing is every week when the episode goes up, we're also going to put up a poll with species requests in the poll that you can vote on for the following week's episode. So y'all will be picking the animals that we talk about, and that's going to be for one of the animals. The other one will be a surprise, because as you all know, we usually do two animals per episode.

Christian: And then we'll switch back and forth as to who's doing the surprise and who's doing the poll.

Ellen: Yes, so one of us will have complete and total freedom, the other one will be a slave to popular opinion.

Christian: But we're still picking what's on that poll, right? Or is it open poll?

Ellen: No, no, no, absolutely not. It will not be an open poll. So we're still taking requests of course, like people- I still want people to tell us what they want to hear, but I'll be selecting a few of those requests to be putting into the weekly poll.

Christian: Sorry botfly fans.

Ellen: We've already done that one. I'm not going to do it again.

Christian: But they want more.

Ellen: I think if we did an open poll, it would just be a bot fly every episode.

Christian: Just a different species.

Ellen: No, absolutely not.

Christian: So who's that first this week? It has been a lifetime.

Ellen: It has been 3,000 years since we were last with you guys, but this week I'm first.

Christian: All right, hit it baby.

Ellen: This week, I'm talking about the Luna moth.

Christian: Very good.

Ellen: Scientific name, Actias luna. This species was not submitted. I'm sorry. I just wanted to talk about it!

Christian: It's alright!

Ellen: This was not a request. I figured, you know, it's been a while since we did an episode. I wanted us to get back into the swing of things with some like, animals that we wanted to talk about, just kind of for ourselves. This one was requested by me. I wanted to talk about it. I requested it from myself. So I'm getting my information on the Luna moth from the University of Florida's Entomology and Nematology Department, which their website can be found at entnemdept.ifas.ufl.edu.

Christian: That's a mouthful.

Ellen: It's a lot! And also the Florida museum.

Christian: Oh cool.

Ellen: Those are my sources for this. So if you've never met a Luna moth, I'll introduce you real quick. This obviously is a moth. Their adult wingspan is typically around 4 to a maximum of 7 inches long, so 4 inches equates to 10.5 centimeters.

Christian: It's a biggun.

Ellen: It is! This is a big ol' moth. It's really big, especially if you're used to those tiny little ones you see flitting around, like inside of your house. This is a big boy. It has a very fluffy white body and it has big, those bushy leaf-shaped antenna. You know what I'm talking about? Where they're kind of tapered, they're kind of an oval shape with a pointy end. Right?

Christian: You said they're white?

Ellen: I'm talking about the antenna.

Christian: Yeah, sorry, I was still stuck on that one.

Ellen: Oh, the body of it?

Christian: Yeah.

Ellen: Yeah. The body of it is white and it's very fluffy.

Christian: I guess I was imagining green for some reason.

Ellen: Well, the wings are green.

Christian: Ohhh, okay.

Ellen: Yeah, so it has these huge, paper-thin light green wings, and they have markings on them that look like an eye spot on each wing. Have you seen a moth that has a spot on there that's meant to look like an eyeball?

Christian: Yeah.

Ellen: Yeah, they have one on each wing and they have four wings, so it's four eyespots in total.

Christian: Ah! Scary and strange!

Ellen: It's a spooky predator with four eyes, I guess. And those eye spots actually kind of resemble crescent moon shapes, which is where the name Luna moth comes from because those eyes look like moons.

Christian: Okay.

Ellen: Yeah. And what's really kind of the defining characteristic of the Luna moth is that their hind wings extend into these long, ribbon-like tails that trail behind them. That's like how you know it's a Luna moth. Right?

Christian: Right.

Ellen: That's like the distinctive trait that they have. That's how they're easily identifiable is with this, this tail.they're kind of the only ones that have a tail like this. It's pretty cool.

Christian: Yeah.

Ellen: I guess there's butterflies that have this, right? A little bit of a swallowtail behind them.

Christian: Yeah. They do that interesting flappy thing as they're flying. I guess their whole wings do an interesting flappy thing, but especially that part.

Ellen: Yeah. You're not how they flap their wings to fly? So that's just kind of generally what a Luna moth looks like. They are found throughout eastern North America, so all the way from Canada down to Florida, all along the eastern North American continent. But I didn't realize that they went all the way up to Canada. So that's pretty cool. The taxonomic family is called Saturniidae. This is a family of medium to extra large moths. These are like, the big boys of the whole moth family.

Christian: Do you have any etymology information about that name by any chance?

Ellen: Saturniidae?

Christian: Yeah.

Ellen: What I saw was that the name comes from the fact that the spots can sometimes have these rings around them that look like Saturn.

Christian: Oh, okay.

Ellen: But it's the eyespots on the wings that make them look like that. That's where the name comes from.

Christian: Because I was, it made me think of the word Saturnalia.

Ellen: Oh, like the holiday.

Christian: Yeah, yeah.

Ellen: Which probably just passed. Or maybe it's coming up? I know it's one of these winter holidays.

Christian: Maybe.

Ellen: Oops. I don't know very much about Saturnalia. Oh well. But I wanted to take a quick aside to delve into some differences between butterflies and moths.

Christian: Very good.

Ellen: Because I think when I first saw Luna moth, I assumed it was a butterfly because it's pretty, and I just thought if it's pretty, it's a butterfly and it's not pretty, it's a moth. But I was wrong.

Christian: The Pokemon method.

Ellen: But so there are some differences between butterflies and moths. One of the key differences being that generally speaking, butterflies are diurnal, so they're active and awake during the day, and moths are nocturnal and they're awake at night and they sleep during the day. So that leads to a lot of interesting morphological differences between butterflies and moths because of their activity times. So since butterflies are awake during the day, they rely more heavily on vision, whereas moths rely more on scent. So you can see this in the fact that the moth has those bushier antennae, so they're collecting more like, particles in the air to collect scents and chemical signals better. So that's why butterflies don't have those bushy antenna because they're using their eyesight to see so they don't have to smell as well.

Christian: Okay.

Ellen: Yeah. And that also contributes to the tendency for butterflies to be more brightly-colored and patterned with these high contrasting sort of like colors and patterns and stuff, so they can more easily see each other in daylight because they're using their eyes. But moths tend to be colored more subtly with like grays and browns. So they're actually going for camouflage.

Christian: Right.

Ellen: So they're trying to stay camouflaged while they're resting during the day. Since they're not trying to find each other with their eyes, they don't have to be as visible.

Christian: They want the opposite.

Ellen: Right? They want to not be visible to each other.

Christian: I've seen moths that look almost exactly like tree bark when their wings are closed.

Ellen: Yeah, yeah, yeah! So that's because they're sleeping during the day, so they don't want to, they want to be able to disguise themselves. And this also explains why moths look fuzzier than butterflies. You know how moths just look fluffy?

Christian: Yeah, yeah.

Ellen: So that's actually a thick layer of scales on the whole body. Those are scales. So the scales trap heat to keep the moth warm at night. So while it's moving, its body is moving, it's generating some friction and those scales trap the heat inside. And butterflies don't need that because they're active during the day so the sun warms them up.

Christian: Right.

Ellen: That's just another way that their activity cycles change the way they look, which I thought was really interesting.

Christian: For sure.

Ellen: Yeah. So other members of the Saturniidae family include the Atlas moth, which is that big, huge, like orange one that has all the crazy markings on it. The Polyphemus moth, which is the one that's known for those big, huge eyespots that make it look like something scary is looking back at you.

Christian: Yeah.

Ellen: Yeah. So some of those other ones that share kind of the similar size and shape of the Luna moth.

Christian: Okay.

Ellen: Those are some of its little cousins. So I'm going to get into our ratings. It's been so long since we've done it. I'm really excited.

Christian: I think the first one was... Tastiness?

Ellen: No it's not! I would not eat a Luna moth. It seems like it wouldn't be very nutritionally dense. Right? You're not going to get much of a meal out of it.

Christian: I mean, I feel like a bat might disagree, but...

Ellen: Oh, I'm going to talk about that. Don't worry. Don't worry. Don't worry. So first category up is effectiveness. And if this is your first time joining us, effectiveness we define as physical characteristics that an animal has that make it better at accomplishing what it's trying to do. I'm, I'm giving the Luna moth a 5 out of 10 for effectiveness.

Christian: Really?

Ellen: Yeah. I was a little harsh on the Luna moth.

Christian: Okay. Starting the new year on that foot.

Ellen: I didn't mean to come back in with such shade. I mean, 5 out of 10 is supposed to be like, passable, right? That's supposed to be like, middle ground, average. Although I suppose if you get a 5 out of 10 on a test, right? That's like a failing grade.

Christian: Yeah, but this is our scaling system. We can...

Ellen: It means whatever we want it to mean.

Christian: Yeah.

Ellen: So I give it a 5 out of 10. So first I want to talk about the life cycle of the Luna moth. So a Luna moth, like other moths, it begins life as an egg. The egg incubates for about a week before hatching into a supremely chonky green caterpillar. It's bright green, it's a little bit hairy. It has those like sparse thin hairs that a lot of caterpillars have.

Christian: Like the scary spiky hair type things?

Ellen: No, it's not- I mean, there's some little spikes on it, but it's, it definitely doesn't look scary.

Christian: Okay.

Ellen: So the caterpillar munches on leaves and it goes through these molts, where it molts about five times over the course of like about a month before it pupates. Pupating means that it spins itself a silk cocoon, and it usually kind of like tries to pupate where there's a bunch of leaves it could blend in with. And then it has itself a nice big nap for about three weeks before emerging from its cocoon as an adult winged moth. So that's its lifecycle. It has very distinct phases of life, right? Caterpillar, cocoon, moth.

Christian: Okay.

Ellen: Very straightforward, very like identifiable in each stage. So I will kind of go into what I gave it points for. So the things it's good at. It has some defenses from predators. So first of all is the eyespots on the wings. So they're meant to like intimidate potential predators or at least to confuse them, right? You might look at it and think, "Oh, those are eyes. I must be looking at some sort of large animal, not just a moth."

Christian: But that would require that predator to be able to see you. Right?

Ellen: Yeah. Yeah. So another thing that I gave them was that their green coloration does give them some camouflage among leaves, cause they typically like to live in forests where there's a lot of leaves around. Though I suppose that's not going to do them too much in the winter. Right? When all the leaves turn like orange and brown. It would work great here in Florida where the leaves are green all year.

Christian: But again that camouflage bit must not be super important since they're nocturnal.

Ellen: Yeah, it's not the most important. So this was kind of the biggest thing I gave it effectiveness points for: the tails. So the tails trailing behind the body are actually a highly specialized defense mechanism evolved to evade one predator in particular: bats.

Christian: Really?

Ellen: Yes. So at night when the Luna moth is flying around, that's when bats are using echolocation to find their prey. Because bats that are preying on bugs like moths would be using echolocation. So when bats are using echolocation, they're relying on sound waves bouncing off of surfaces to tell them the size, shape, location of what they're going for. The Luna moth's twin trails that are flapping behind the moth trick the bat into thinking that those are actually the wings of a smaller moth, like a little bite-sized moth that would be very easy for the bat to capture. So the bat gets confused, it thinks that that is the moth and it attacks the tails and the tails just rip right off and the Luna moth is able to get away.

Christian: Huh.

Ellen: Yeah. So it's a little evasion tactic, right? It's kind of like how a lizard can drop its tail and run away.

Christian: Sure.

Ellen: But I couldn't give them too many points for this because while that is really cool and really clever, the tails don't grow back. So this only works once.

Christian: One and done.

Ellen: It's going to get you out of a tight spot one time.

Christian: I guess I was, my guess was going to be that the tails made it look like a bigger animal than it was, but... Quite the opposite.

Ellen: Not really. Now those do not protect them from our walls.

Christian: Oh, okay. That would make sense.

Ellen: Yes. Because owls are actually relying on vision and this is a highly visible moth. So, so yeah, owls will just chomp right down on these little guys.

Christian: Interesting.

Ellen: Mhmm. People often will find owls' nests, and on the forest floor surrounding the owl's nest will just be like all sorts of like dead Luna moth like wings scattered around on the floor.

Christian: That would be something neat to see in a game like Skyrim, where you come across a nest of some sort and it's just surrounded by moth wings.

Ellen: Yeah. So that's essentially what's going on here. Cause that's such, that's a strategy that's made for the bat, but it doesn't work for the owl that's not relying on sound.

Ellen: Hate to see it.

Ellen: I know! So, the last kind of defense that I gave it is actually for the caterpillar. The Luna moth's caterpillar can try to deter predators by first it makes this clicking sound that can be like, kind of startling. It's like a clicking, like a rapid clicking sound. And then if that doesn't work, that is a warning for what they do next, which is regurgitating a nasty liquid that smells and tastes very, very bad. So it makes the caterpillar less appetizing.

Christian: I mean how nice of them to give a warning first and not resort to that.

Ellen: Yeah, I mean I would imagine if they were threatened enough they would do both. Right? Just... [Spraying sound]

Christian: It's got to come with a cost though, right? I mean that's nutrients that it's getting rid of.

Ellen: Yeah. you don't want to do that too much. Right? That's not something you can do all the time. But yeah they will... [bleh]. So that brings me to the deductions for the Luna moth's effectiveness. So the adult Luna moth only has vestigial, completely useless mouth parts.

Christian: Oh!

Ellen: They don't function at all. So once the Luna moth has wings and can fly, its sole purpose is reproduction. It does not eat at all. It's just trying to find a mate and that's it. So that being the case, the adult Luna month only lives for like a max of one week.

Christian: Wow.

Ellen: Usually less than that. Usually it's only like a few days but a maximum of one week. Cause it's not eating! It can't live that long. They really put themselves on a timer, right? Like they have severely limited their amount of time available to them.

Christian: So that's quite a week of both hunger and thirst, huh?

Ellen: [laughs] Oh nooo! Yes. Both of those things. So that's only one week, and that's only like an eighth of its lifespan. So, it's only an adult for like a little blip in its life really.

Christian: Okay.

Ellen: Which I think is kind of crazy. Right? So this whole thing of like discarding the feeding mechanic is actually not really uncommon for moths. There actually a lot of moths that do this where the adult form just doesn't eat at all. They're like, you know what? We're done. We're done eating. We're just not doing it anymore. Earlier I mentioned the Atlas and the Polynemus moths, both of them are done eating once they are adults. And actually we, the last episode that we did was the European eel and they also stop eating when they're adults.

Christian: Really?

Ellen: Do you reme- Yes, really. I just talked about it.

Christian: That was like, a month ago, Ellen!

Ellen: But the European eel had a much more daunting task ahead of it, cause it would stop eating and then have to cross the Atlantic ocean.

Christian: It's like, "I have to go here." Why not somewhere closer? "NO."

Ellen: That's what I said! That's what I said! But so they're kind of playing on hard mode, you know? And that sucks for the Luna moth because the Luna moth has these really, really delicate wings that tear very easily. So...

Christian: Womp womp.

Ellen: Like even just like minor, very gentle handling can cause like damage to the Luna moth's wing.

Christian: I mean I guess that's what it's designed for, because you don't want it to be so sturdy that even if a bet catches you by the those parts, it still has your entire body.

Ellen: Yeah. You want them to be kind of tearaway, but then that really just kind of- when that's your only method of getting from point A to point B... Yeah.

Christian: It is what it is I suppose.

Ellen: I guess. So my takeaway here was that the Luna moth spends the largest portion of its life as a caterpillar, and honestly the caterpillar is better equipped for survival than the adult Luna moth. It's like, more powerful as a baby than it is as an adult. Even though its only method of movement is squirming around on little tiny caterpillar legs and it doesn't have its wings yet, at least it still has a mouth. So I think the Luna moth caterpillar is actually a little bit more buff than the Luna moth adult. This is like a Pokemon that you don't- you actually don't want it to evolve because its stats in its like base evolution are better.

Christian: But it's prettier!

Ellen: It, yeah, it is pretty. For our next category is ingenuity, and we define ingenuity as behavioral adaptations that give the animal an edge over maybe other animals or let it solve problems it's encountering on a sort of daily basis. And for ingenuity, I'm giving the Luna moth a 3 out of 10.

Christian: Okay. Kind of to be expected of an insect, I suppose.

Ellen: Yeah. So kind of the whole stereotype of- so think of the moth lamp memes. They hold true for the Luna moth. The Luna moth has a strong attraction to light, specifically UV light.

Christian: Huh.

Ellen: Yeah. So Luna moths will be drawn towards a light source. So this is why most of the time when you hear about people seeing them, it's at night when they have come to, for example, like a porch lamp or a streetlight or something.

Christian: Yeah.

Ellen: They'll be drawn towards that, towards that light source.

Christian: So what is the reason for the Luna moth to be attracted to that?

Ellen: I do not know. I'm sorry. I would imagine just like since they don't see very well, maybe like any sort of light source would give them better vision? So they would need to fly towards it so that they can see better?

Christian: But then they just hang out there.

Ellen: Yeah, I do not know. Maybe they're just hoping that like, hey, there's something I can see! I hope another one of my species is also going in that direction and is receptive to me mating with it. Like maybe it's just a landmark that they can converge on that is easier for them to see.

Christian: I guess so.

Ellen: Yeah. Actually light pollution can interfere with Luna moth's mating patterns and it can impact their populations in more urban areas where the moth is being kind of distracted by the light and it's not focusing on finding a mate like it's supposed to be.

Christian: Huh. Interesting.

Ellen: Yeah. That sucks. So its behavior during these like phases of its life are very simple and very goal-oriented. It's there for feedin' and it's there for breedin'. But yeah, feedin' and breedin', that's, that's what the Luna moth does. It has those two goals and that's all it really cares about.

Christian: It's admirable, really.

Ellen: And I also had to deduct some for the fact that female Luna moths tend to meet with the first male that reaches her.

Christian: I mean when you're operating on this kind of timeline...

Ellen: I was just like girl, come on. Have some sort of like selection standards, right? Like maybe one of them has longer, like wing tail ribbon things or maybe one of them is a brighter green, but she's like, "Nope! You are near me."

Christian: She is hangry. She is going to die soon.

Ellen: That clock is ticking. She is on a schedule so she's not here to waste time.

Christian: Things want to eat her.

Ellen: 3 out of 10 for their ingenuity. And this brings me to our final category for the Luna moth: aesthetics. Easy. Come on. 10 out of 10. This is like, THE pretty bug.

Christian: It is.

Ellen: I keep saying bug. I'm sure they're not a true bug. I'm just saying, they're so beautiful. They're mystical looking, right? Like you look at them and they look like they should be in some sort of like, fantasy movie about elves and dragons and stuff. Right? Like they look like a fairy that's flying around in our world for some reason. And you're like, how did you get here? Like, how are you extant in this realm? Like they, they don't look like they belong on earth. Right?

Christian: Yeah, yeah.

Ellen: They look like some sort of fae. So it's a very successful look. I find them really perfect and wonderful. So 10 out of 10 Oh, and that's specifically for the adult form, right? Like the caterpillar is... It's a caterpillar, but that's all.

Christian: It is a pretty butter- I almost said butterfly. A pretty moth.

Ellen: See? I think they look like butterflies. Right?

Christian: Yeah.

Ellen: But they're not. They're moths. But, so that's why whenever people say that butterflies are pretty and moths are not, bring out the Luna moth. That's your example right there. They're beautiful. I think the Luna moth is prettier than any butterfly. There. I said it. That's my hot take.

Christian: Whaaaat? I don't know...

Ellen: Show me, this is my challenge to our listeners. Show me a butterfly that's prettier than a Luna moth.

Christian: Okay, I'll find one too.

Ellen: You will? Okay. Well the race is on. But so to wrap up for the Luna moths and miscellaneous information, their conservation status is not evaluated. Lots of people think that Luna moths are very rare, but that's actually not necessarily the case. So the species itself is not rare, but since their adult form is such a small little sliver of their lifespan, an eighth of their life, they spend as this fully grown moth with wings and stuff and also very easily killed in this form. Right? So they're not going to make it but a couple of days probably. So since that they're only in adult for a very small little portion of their life and then their caterpillar and cocoon phases are completely unremarkable. Right? They look like any other caterpillar or moth cocoon or whatever. You're not going to look at one and think, "Oh my gosh, that's a Luna moth." Right. So you're not likely to notice or recognize them during seven eighths of their lifespan. So they're not actually as rare as people think they are, you're probably seeing them more than you think. They just look a little bit more drab in their other, less visually successful forms.

Christian: Makes sense.

Ellen: Yeah. So we have seen Luna moths twice. We saw them one time in our first apartment that we ever lived in. Christian came home- you must have come home after me, cause I remember you coming inside and saying, "you gotta come out here and look at this moth." I was like, what? And so I came outside and there was a Luna moth on the wall outside of our apartment. It was just sitting there chilling out and we all- I got to run inside and get my camera and take a bunch of cool pictures of it. Um, my, he's now five years old, but he would have been two or three at the time, and he got to come out and look at it and that was really cool. And then another time we were just sitting at a Starbucks chatting outside and a Luna moth just flew right by.

Christian: Yeah. It was like, broad daylight.

Ellen: Yeah. Which is weird cause they're nocturnal and they're not usually active during the day time, but one just flew right by us like right. Like over our table and fluttered off into the... Into the sky

Christian: I don't remember what we were doing that day, but it was a good sign.

Ellen: Yeah, it was nice. You know what I think we were doing for real though?

Christian: What's that?

Ellen: I think we were shopping for my engagement ring.

Christian: Awww.

Ellen: I think we really were because I think that we were at that Starbucks next to the store.

Christian: Yeah.

Ellen: So it was really nice. That's the Luna moth.

Christian: Thanks honey.

Ellen: You're welcome! Okay baby. That was my animal. It's your turn.

Christian: Okay. This week, on our first episode of 2020, I bring the koala.

Ellen: Delightful. How wonderful.

Christian: Yes. Scientific name, Phascolarctos cinereus. And this species was submitted by Benjamin Lancer. Thank you Benjamin. I'll be using information from National Geographic as well as Animal Diversity Web. So first I want to talk a little bit about its naming. So its scientific name, Phascolarctos, has two words in there and both are from Greek. The first one comes from Phascolos, which means pouch or bag. And then the second one is arctos, which means bear.

Ellen: Oh! Bag bear.

Christian: The species name, cinereus, is Latin for "ash-colored."

Ellen: Oh. Okay.

Christian: Yeah. And I think that's a little on the-nose for... Well, I'll talk about it later.

Ellen: Grey bag bear.

Christian: I meant like, ash being used as...

Ellen: *gasp* Oh no.

Christian: Yeah. But anyway, it's common name "koala" comes from the language Dharuk, which is an Australian Aboriginal language that was spoken in the regions of Sydney and New South Wales. And it comes from the word gula, which means no water.

Ellen: Oh, no water.

Christian: So I'll come back to why that is.

Ellen: Okay.

Christian: But I'll just jump right into the basic information. In terms of their size, they range from 23.5 o 33.5 inches, or 60 to 85 centimeters. They weigh around 20 pounds or 9 kilograms, and the males are larger than females. They can be found in a huge swath of Eastern Australia. They belong to the taxonomic family Phascolarctidae. Usually I like to talk about evolutionary relatives here, but the koala is actually the only extent species in that family.

Ellen: Really?

Christian: Yes. And the closest living relatives are wombats, which are in the Vombatidae family.

Ellen: Okay. Can see that. I can see a little bit of resemblance there.

Christian: Right. So jumping right into our first category of effectiveness, and I'm giving the koala a 7 out of 10 for effectiveness.

Ellen: Excellent.

Christian: And I had to think about here, what are the things they're supposed to be doing and how good are they at that?

Ellen: What are they supposed to be doing?

Christian: Rather than trying to look at them in a big picture. So first and foremost: not bears.

Ellen: Yeah, a lot of times people call them koala bears. Right?

Christian: Yes. And even their scientific name has "bear" in it. But they are not bears. They are marsupials.

Ellen: I don't know who dropped the ball on that, so hard.

Christian: I dunno.

Ellen: That's ridiculous.

Christian: Probably European colonizers.

Ellen: Thinking everything's a bear. That's ridiculous. It don't even look like a bear, y'all.

Christian: And for those unfamiliar, being a marsupial, they are a pouched mammal, meaning they have a pouch that they keep their young in. The female koala carries babies in their pouch for about six months and the infant rides on the mother's back or clings to her belly for about a year after that.

Ellen: It's so cute.

Christian: It is. And other examples of marsupials, kangaroos of course.

Ellen: And the quokka! We talked about the quokka.

Christian: Yes! The quokka! The worst parent.

Ellen: Is the koala a better mom than the quokka?

Christian: I assume so because I didn't read anything about homicide.

Ellen: Is a baby koala called a joey?

Christian: It is.

Ellen: Oh, I love it! That's great.

Christian: That seems to be a common thing with marsupials.

Ellen: I think that is the convention.

Christian: Yeah. I want to talk about their diet. This is a common known thing about koalas. They eat primarily the leaves of the eucalyptus tree.

Ellen: That is the only piece of information that I know about the eucalyptus tree. That's it. Like I have such a tight cognitive connection between koalas and the eucalyptus tree that those two pieces of information are inseparable in my mind.

Christian: I think it's because koalas are often depicted in media, and that's one of the things that is usually depicted about them, is that they're always eating eucalyptus leaves.

Ellen: That is such a strange, weird aspect of the koala for so much pop culture to really zero in on. Right? Like I feel like there's no other animal where they just really are hammering the point home of what they eat.

Christian: Panda is actually a good example, right? Because what's the one thing most people know about pandas?

Ellen: Oh, yeah.

Christian: They eat bamboo.

Ellen: Sure.

Christian: I think it's because it's their primary food source. Like not very many animals have that, like ONE thing that they eat.

Ellen: Oh yeah, that does make sense. I guess because it is so specific, then it sticks out more.

Christian: Yeah. Yeah. And there are some other parallels with pandas that I'll talk about here shortly.

Ellen: Oh good!

Christian: And by pandas, I mean giant pandas, by the way.

Ellen: Not the OG original panda.

Christian: Not the cute ones. I'm just kidding. They're both cute. Okay. So, talking about them eating and such, the first thing I found that I was legitimately surprised by was that they are most active at night.

Ellen: I didn't know that.

Christian: Yeah.

Ellen: You wouldn't think with their eyes being so tiny that they would be nocturnal, right?

Christian: Yeah, yeah.

Ellen: Usually a nocturnal animal has very big eyes, but the koala has little beady eyes

Christian: Yeah, they're teeny. And they get most of their water from the food that they eat. So going back to that name of "no water," that's what that's referring to. Even early explorers of Australia saw this habit of them almost never drinking water, and they thought at first, this thing obviously doesn't need water to survive.

Ellen: Oh, okay.

Christian: But what was actually going on as they get most of their water from the eucalyptus leaves that they eat.

Ellen: That makes sense. That was something that I talked about with the Arabian camel, too. How, like when water sources aren't so easy to come by, then you've got to get your water from different sources.

Christian: Yeah. And they'll even eat up to around two and a half pounds or 1.1 kilograms of food a day. That's a lot.

Ellen: That's very many leafs.

Christian: That's like over 10% of your body weight. And they have to, right, cause it's not, especially nutritious.

Ellen: It's mostly just like water and fiber, right? Yeah.

Christian: Yeah. Low protein, high fiber.

Ellen: Like the sloth!

Christian: They'll even store some leaves in their cheeks. Yeah, they have cheek pouches.

Ellen: Oh my gosh. That's very cute. That's very good.

Christian: So they have this special digestive track that lets them eat this very specialized diet of mostly eucalyptus leaves. And that's important, one, because difficult to digest otherwise, but also to most mammals, eucalyptus leaves are toxic. Yes.

Ellen: Poison. Don't eat, do not eat the leaf. Bad leaf. Danger leaf.

Christian: I tried to look into this a little bit. This, with humans, is mostly a problem with essential oils, with the eucalyptus essential oil where it's not diluted and someone uses way, way, way too much. Usually kids. But there's a lot of cultural thoughts around what eucalyptus does medically, but I couldn't find anything scientifically substantiated there. But that's okay. It smells nice, I guess.

Ellen: I want to say I've used like a shampoo that had like eucalyptus ingredient in it.

Christian: Yeah. And they even have specialized teeth for eating these leaves. So if you look in their mouths it kind of looks like they have a front teeth for just pinching off the leaves, and then the rest of their teeth is just one big molar basically.

Ellen: Whoa. That's weird. That's very strange. I would imagine that being specialized to eat something that not very many other things are going to eat, because it's poison, probably reduces competition for that thing. Right?

Christian: Probably. Yeah.

Ellen: Cause if nobody else was trying to eat it, it's all yours. More for you. Right.

Christian: They are their own biggest competitors I think. Cause I'll mention this again later, but a single adult koala needs a territory that includes about a hundred trees to sustain itself.

Ellen: I guess that makes sense when you have to eat that many leaves.

Christian: Yes. Something I forgot to mention cause, I guess maybe at the time I thought it was widely known already, but just in case: the koala is arboreal. It spends most of its time in trees.

Ellen: Where them good leafs are at.

Christian: Yes. They sleep for up to 18 hours. 18 hours.

Ellen: Like at a time or like...

Christian: That's a good question. I didn't look. But if they're mostly active at night, it would make sense if they were doing 18 hours straight and then up for... What is that? Four- Six hours during the night?

Ellen: You know, that would be consistent with their diet though. Because if it's such a low nutrient diet, they don't have a lot of energy to be wasting during the day. Right?

Christian: Yeah. So a lot like the sloth, you know, they're conserving energy. So I just mentioned how they climb trees and they have some very special feet to allow them to do that very well. So they have a total of six opposable thumbs.

Ellen: What?

Christian: Yes. So you might be wondering, but Christian, they have four limbs, how does this work?

Christian: Okay...

Ellen: So, their front paws. Each has five digits. Two of them are thumbs.

Ellen: Hold on. If you could see me right now, the little- it's the math meme where like all the math is floating around my head and I'm doing it trying to do this mental math. Four feet, five, what was it? Five...

Christian: Six total thumbs.

Ellen: Six thumbs?

Christian: Yes.

Ellen: Which feet are doubled up on thumb?

Christian: So it's the front ones.

Ellen: The front ones are double-thumbed.

Christian: Right. So the front feet, each have five digits, two of which are thumbs.

Ellen: Okay. So I'm looking at my own hand and I'm imagining that my thumbs are thumbs, and then my pinkies are thumbs.

Christian: No, not like that. So if you count your digits, your thumb being your first toe, and then your pinky being your fifth, on koalas on their front paws, the first and second toes are thumbs.

Ellen: So my thumb and my index fingers are my thumbs.

Christian: Yes.

Ellen: Okay. That's creative.

Christian: Right? And each one of those digits has a claw.

Ellen: Okay.

Christian: Now let's talk about their back paws. Their back paws also have five digits each, but they have one clawless thumb on them.

Ellen: Man, at least they have thumbs on their feet. Must be nice. I'm kind of jealous.

Christian: The rest of their toes are clawed. But, interesting about these toes on their back feet, the second and third toes are fused together.

Ellen: Does that even count as two toes then?

Christian: Yes. If you saw it in a picture, you would see why, because it's not the whole digit that's fused. It's about, I don't know, 80% of the length is fused together cause they still have two claws at the end of this fused digit.

Ellen: Okay.

Christian: And they use that to groom themselves. Like, as a comb.

Ellen: Huh. Well dang, that's cool. I wish I had that. I want to have multi-tool feet.

Christian: So yeah, so they have two thumbs on each of their front paws and one thumb on each of their back for a total of six thumbs.

Ellen: I didn't think that their sort of like digits were going to be so complicated.

Christian: Yeah. And so they're the designed so that they can grasp tree branches very, very well., and also just climb in general.

Ellen: Sure.

Christian: So yeah, that's a 7 out of 10 for effectiveness, cause I figured for what they're doing, you know, eating and living in trees, they're built pretty well for it.

Ellen: This is something that I feel, similar to the sloth, people look at the low-nutrition diet, they look at the low-energy lifestyle and they assume like, this animal is bad at life because it eats a dumb food and it doesn't move around very much. And they assume like, oh this animal is very lazy and very poorly adapted. But it's actually kind of just making the best of what it's got. Right?

Christian: Yeah, yeah.

Ellen: It can't, it doesn't have access to a lot of water sources, so it has to be eating a diet that's high in moisture, which it's getting from leaves. So since it's eating a lot of leaves, it can't be using a lot of energy so it has to sleep a lot. Right?

Christian: Yep.

Ellen: It makes sense when you consider the whole situation that it's living in, it's actually pretty well adapted to that.

Christian: Very much so. Yeah. And the reason I guess I didn't give it a full 10 out of 10 is because it doesn't have very many adaptations in terms of avoiding predators.

Ellen: Oh sure. Like not a lot of defenses. Right?

Christian: Yeah. Yeah. But yeah. So speaking of that, that's actually going to be one of my points for ingenuity, which I'm giving a 5 out of 10 for the koala.

Ellen: Awww...

Christian: So yeah, just feeding in the tops of the eucalyptus trees keeps them out of reach of most predators. Next up on ingenuity, I want to talk about how, they know which eucalyptus trees are safe for them to eat, because there are hundreds of species of eucalyptus trees.

Ellen: Oh! I hadn't thought of that.

Christian: There's a group of trees that are safe for them to eat, and among those they have favorites.

Ellen: Really? Aw! Like favorite species, or favorite trees in particular?

Christian: Species.

Ellen: I thought you meant they have favorite trees. "This is a good tree. I like this one."

Christian: No, like the ones that they think tastes the best.

Ellen: Okay. And does that vary from koala to koala? Do they have like, personal tastes?

Christian: I don't think so? I think it's more of a species-wide thing. Like they as a species have a preference for a particular species of eucalyptus trees.

Ellen: Okay.

Christian: And before I get into my last point for ingenuity, I just want to talk about one difference in the koala as a marsupial as compared to other marsupials. So most marsupials, their pouch is situated in such a way that the opening is facing the head of the animal. Right? So like, when you think of a kangaroo, the opening, when the baby comes out of that pouch, they are facing the mother's face, right?

Ellen: Sure.

Christian: With the koala, that is turned around 180 degrees.

Ellen: So the baby's facing the mom's... Butt?

Christian: Butt. Yes.

Ellen: Oh no...

Christian: And here's why!

Ellen: No, no, no, no, no, no, no.

Christian: So the babies, when they're born, do not have the gut bacteria to digest eucalyptus leaves safely.

Ellen: Okay.

Christian: And much like the giant panda....

Ellen: This is fine.

Christian: Yeah. They must ingest a special form of their mother's feces to get that gut bacteria.

Ellen: Okay. All right. That's fine I guess.

Christian: So that's, that's what happens there.

Ellen: Thanks. Great.

Christian: But there's still nursing of course there. There are, I guess you would call them mammary glands that are accessed from the pouch.

Ellen: Right. Yeah. There's still mammals, right? They're still nursing their offspring.

Christian: Yes. So that's what all that's about to make sure they can eat the eucalyptus leaves at all.

Ellen: A fine diet of mother's milk and...

Christian: Everyone has that home recipe they love.

Ellen: Oh my God! Gross! I hate iiiiit!

Christian: I got that bit of information from the BBC, I should mention.

Ellen: Fantastic.

Christian: Because I saw it hinted at in other articles, but they didn't come right out and say it. The one I first saw it in mentioned the babies "will eat food that has passed through the digestive system of the mother." I'm like, wait a minute...

Ellen: Cause that still leaves it open to interpretation. Like does the mother regurgitate like a bird does? It's like, nope...

Christian: I had a suspicion based on the diet. I was like, this is sounding a lot like the giant panda.

Ellen: They were really dancing around that, huh? Like they really didn't want to be gross about it.

Christian: Yep.

Ellen: But we're not afraid to go there on this show.

Christian: Not at all!

Ellen: Gross.

Christian: So that's a 5 out of 10 for ingenuity. I couldn't give them any more points. I didn't see anything smart or intelligent in terms of tool use outside of that.

Ellen: Sure.

Christian: Last category, aesthetics. I'm going to give a 7 out of 10.

Ellen: That's about right, I think.

Christian: So they look very cute and soft, but that's about where it ends.

Ellen: I don't... I don't think they're that cute. I don't. It's eyes. The eyes are very small and I'm not about it.

Christian: The nose is pretty unique, I think.

Ellen: It is.

Christian: It's kind of like the- a wombat has a similarly shaped nose and face, I think. Their ears are pretty cute and fluffy.

Ellen: That's true. They do have fluffy ears and that's great.

Christian: But as we mentioned before, they do have weird feet, that can be off-putting.

Ellen: Oh gosh! Have you seen them like, walking on all fours on the ground?

Christian: Yeah. Cause they're, they're not made to do it.

Ellen: It's so weird! It's very strange. Their body is shaped in a very strange way.

Christian: Yeah. Uh, they don't sound cute. Go on YouTube. Find a recording of what they sound like. Not cute. It's like a low grumbling and...

Ellen: [very bad koala impression].

Christian: Yeah. Not cute.

Ellen: Wait, hold on...

Christian: No.

Ellen: Yes.

Christian: No.

Ellen: Yes. One, just one time please!

Christian: Not doing it.

Ellen: Pleeeeeease.

Christian: Nope.

Ellen: How nicely do I have to ask to get you to do a koala impression?

Christian: Moving on to my final aesthetics point...

Ellen: I did it!

Christian: It's enough. They smell like cough drops because of the oil in the eucalyptus.

Ellen: Oh my- what?

Christian: Yes.

Ellen: Okay. I've never met a koala, and this is definitely one of those things that I, I wouldn't have thought. What? They smell like cough... Do they smell like Ricola cough drops or like those weird like drugstore cough drops that are like, gross cherry flavor?

Christian: I don't know, I'm not a connoisseur...

Ellen: Of cough drops?

Christian: But, I usually opt for the fruity flavored ones when I require them.

Ellen: Gross. Those are the worst ones.

Christian: But yeah, I guess they smell like cough drops that... Whose ingredients include eucalyptus.

Ellen: Okay. I wouldn't call that a flattering smell. That's not a smell you want to smell like.

Christian: There are worse smells.

Ellen: That's true. There are worse things you could smell like, but...

Christian: I would argue most wild animals don't smell that good.

Ellen: Okay. I guess when we're looking in the grand scheme of things, at most of wildlife, yes. Cough drop is an improvement of sort of your base wildlife flavor. Except the binturong has the number one spot for best natural smell.

Christian: What's that?

Ellen: Popcorn.

Christian: What!

Ellen: They are- they naturally smell like buttered popcorn.

Christian: Hey, real quick.

Ellen: Yeah.

Christian: What's a binturong?

Ellen: It's bear cat.

Christian: Oh okay. I was imagining like a deer or something.

Ellen: Nah, nah, nah, nah.

Christian: So that's my 7 out of 10 aesthetics. Moving onto some miscellaneous info, starting with conservation status. They are listed as vulnerable, population decreasing by the IUCN. They were over-hunted in the 1920s and 1930s for their warm, thick coats. Probably not really needed in Australia, but I'm sure exported elsewhere.

Ellen: Well also Australia was kind of a colony, right? So they were probably just kinda shipping them back to Europe.

Christian: Sure. But they are now illegal to kill. And also, re-introduction helped bring them back, but their populations are still smaller and more scattered than they were prior. They're vulnerable to habitat loss. As I mentioned earlier, one animal needs about a hundred trees to sustain them. That's a lot.

Ellen: Yeah.

Christian: And the final point I will talk about is the Australia bushfires that are in the news for the past couple of months.

Ellen: Yes, please.

Christian: So if you're not paying attention to the news or just don't know, Australia has been experiencing devastating bush fires since about August. And there currently there are fires in every state, including some areas populated by koalas. So Australia has what they call a "fire season," but this year it started earlier than it normally does and it's also much more intense than it usually is. So the reason why I'm bringing this up specific to koalas is because there's been a headline floating around news media and also social media that koalas, because of these fires, are functionally extinct. I just want to talk about what "functionally extinct" means real quick. It means a species no longer has enough individuals to produce future generations or play a role in the ecosystem. The koalas have definitely been impacted, but are nowhere near being functionally extinct. So koalas are particularly at risk to the fires because of the intensity of the fires that are going on right now and also their lack of a way to escape quickly.

Ellen: That's true. They're not quick.

Christian: Yeah. So in many cases, the koalas will climb higher into the trees to escape fire. That's sometimes enough to escape, because eucalyptus trees are pretty big. But with the fires that are going on right now and how intense they are, it's not enough and can even cause the oils in the tree to make the tree explode.

Ellen: What!

Christian: Yes.

Ellen: Oh my gosh!

Christian: Yes.

Ellen: I didn't know about that.

Christian: Yes. And going back to how they don't have a quick way of escape, you know, they just can't move quickly enough to escape fires unlike birds or kangaroos.

Ellen: Sure.

Christian: Right. So another headline you'll see maybe is that 80% of their territory is decimated. But as of November 25th, a National Geographic article was posted that said the recent fires in new South Wales and Queensland covered 1 million hectares. And for those unfamiliar, a hectare is equal to 10,000 square meters. But, the koala's habitat in Eastern Australia covers over 100 million hectares. So that's way more than has been burned or effected. Now, that number, because this article was a month ago, I think that number is closer to 5 million hectares in all of Australia. But still, that's...

Ellen: Not 80%.

Christian: Yeah, nowhere near. And also just because an area has been affected by the fire does not mean it's destroyed or will never be suitable for habitat again, because the eucalyptus tree in particular is adapted to be in an area that experiences bushfires often. So they'll make a comeback usually.

Ellen: You know, I get why they wanted to really highlight the urgency of conserving koalas. Right? Cause it's like, they need the-yes, they do need help and they need conservation efforts, but they're a lost cause, as being functionally extinct might imply. Right? Like, that might imply there no hope for them left and they're too far gone that they're, you know, extinct in the wild or something. But that's not the case. Like we can still make things happen for them. We can still help them and they're still out there. They're still reproducing and making baby koalas.

Christian: Yeah, yeah. And it's not to say they are totally immune to the fires cause they're, they're definitely being affected. You see stories in the news about you know, a person saving a koala and then that koala going to like a hospital for koalas. We've seen that a couple of times, right, in the past months.

Ellen: Yeah. These stories are popping up all over the place of people rescuing koalas that- and they look so, they look so sad. It's heartbreaking! You see them like, covered in just like black, just soot from the fires...

Christian: Well, where their hair is burned and the skin...

Ellen: Yeah, the poor babies, they just, they're in such a rough state. But you know, koalas are kind of a national icon, right? Like regardless of whether you're familiar with Australia or not, you probably are familiar with a koala.

Christian: Right.

Ellen: You probably know about koalas, and you probably like koalas. So it's a good way to get people's attention by saying like, "look, this is posing a threat to koalas," because they're one of those charismatic species a lot of people like and find cute and want to help. So, like how we talked about with the giant panda, you know when we talk about conservation efforts for the giant panda, it's not just the giant panda, right? Like protecting giant panda habitats is going to have a domino effect where it's going to protect a lot of other species that share the habitat with the giant panda. So it's a net gain really. If you have to just use the koala as like, the face of the operation, then that's the way it's going to be. So like I get where they were going with it, but you know, kind of putting the urgency on the koala because people like koalas.

Christian: Yeah. So, I won't delve into this much deeper, but the issue of the bush fires in Australia has gotten very, very- not just important, but also kind of on the, on the world news, like the world's eyes on it because of how big the fires aren't, how intense they are. People have died, lost their homes. It's, it's intense. And it's also become a bit of a political issue with how individuals in Australia's government are reacting to it. But yeah...

Ellen: We are not Australian, so we- we're not informed enough to comment on Australia's political climate. So I don't think that's our wheel house, but we can talk about koalas.

Christian: Yep. So koalas just kind of are the poster child, in some ways, of the disaster.

Ellen: Benjamin Lancer, when requesting the koala, actually included some charities that are helping koalas on the ground in Australia. So the relevant ones that he included in his email were New South Wales Rural Fire Service, the Port Macquarie Koala Hospital, New South Wales Wildlife Rescue Services, and the World Wildlife Fund has an emergency appeal centered around wildfires.

Christian: Okay.

Ellen: Yeah. So those are all resources that, if you are so moved by the plight of the koala and the other animals living in Australia that are threatened by these wildfires, those are all good resources for you to look into.

Christian: Very good. So that's the koala.

Ellen: Very good. Thank you for the koala. I kind of expected you to dunk a little harder on the koalas, because there's a lot of sort of negative discourse about koalas on the internet. It's like the sloth, where people set up this expectation for you to hate on it, but then you do a little bit more research, you're like, well, actually they're just adapted differently than humans. Right?

Christian: Yeah, yeah.

Ellen: They're just adapted to different situations, so...

Christian: Well, I think a lot of it comes from an expectation of what koalas are, based on what you see in the media. And then once you see some, you know, actual footage and whatnot of koalas, it differs greatly, but that's not their fault.

Ellen: They're meaner than you think they are.

Ellen: Yeah. Yeah, a little bit.

Ellen: They're not friendly. Like you look at them and you see videos of people cuddling with them and loving on them and stuff, and you think, "Oh, it's just a sweet Teddy bear." Oh, they're not! They will get you. They do not care. Have you seen that video of the guy that gets a koala trapped in his car? That thing is mean!. It's like a, it's like a raccoon.

Christian: Yeah.

Ellen: Thank you. I know so much more about koalas now. I don't know if I'm better for knowing about their, uh, rearing habits. *gasp* Child rearing!

Christian: Oh noooo...

Ellen: Because it's... their rear. End.

Christian: I'm just, I'm thinking animals that have this kind of diet, this has to be a common thing. There's no relation between this and the giant panda, and they're also geographically very differently located.

Ellen: But similar diets, so...

Christian: Yeah. I'm guessing if we found other animals with this kind of diet, I'm betting, we would also see an association with that method of gut bacteria generation.

Ellen: I didn't see it with the sloth, so..

Christian: I'm gonna dig!

Ellen: Okay. Thanks, I guess I don't know how I, it's like you took like a species that I expected to be very benign and not have any unsettling content whatsoever, and you manage to find it somehow.

Christian: I hunt for it.

Ellen: You actively seek out something to make me regret all of my choices that has led to where we are now. Thanks.

Christian: Anytime.

Ellen: Well thank you darling and thank you to everybody who has listened to us. We love y'all. Thank you for joining us. We really appreciate your time. You can connect with us on Facebook or Twitter or Instagram by searching the title of the show. That'll get you there. Definitely, you know, follow us on Twitter and join our group if you want to be involved in the voting process for picking animals cause we're hoping that that's going to be a way for y'all to have more involvement in what the show ends up being. Right? Like it's, I feel like it's an opportunity for you guys to influence the direction we go in. I think that's going to be a great way for the audience's voice to ring through in the show.

Christian: Yeah. And if nothing else, animal memes.

Ellen: That's true. Hit us with your best memes. We love that. So if you have animal species that you want to hear us review, submit those to us either on social media or via email. I can be emailed at ellen@justthezooofus.com. A transcript of this episode and other episodes can be found at our website, justthezooofus.com, and to wrap up, I want to thank Louie Zong for letting us use his song "Adventuring" as our theme music.

Christian: Yes. Thank you so much.

Ellen: Thanks, we love it. We think it sets a good tone.

Christian: .......It does.

Ellen: Why are you like this? Anyway, byeee!

Christian: Bye y'all.

32: Inca Tern & European Eel

Ellen: Hello everybody, this is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And we are here withJust the Zoo of Us, your favorite animal review podcast where we take your favorite species of animals and review them and rate them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: We are not zoological experts, although I like to think we get closer to that one step at a time every week.

Ellen: You're just listening to us take our very own independent study course in zoology.

Christian: From Google university.

Ellen: We don't just Google, Christian.

Christian: That's where it starts, for me.

Ellen: Listen, every journey of a thousand miles begins with a single step.

Christian: A single Google.

Ellen: Speaking of that, we do a lot of research and we make sure that we're bringing you information from good, trustworthy sources.

Christian: Definitely not made up.

Ellen: Definitely didn't make any of this up. Before we get into our animals, I wanted to just update folks with two quick things, the first of which was kind of a win for us. This past week was Giving Tuesday, and we were able to donate $85 to the Wildlife Conservation Network this year, and that was all of our ad revenue for this year.

Christian: Yeah, so that was one of our earliest goals with this project. So it was a good feel-good moment.

Ellen: It was really cool. And we were able to do that because of all the support that we have received from our Patreon and from our live show revenue and stuff like that, that was able to make it possible for us to donate our ad revenue. So if you listened to us at all this year, you had a hand on that ball, so thank you to everybody who helped us be able to do that.

Christian: Yes, thank you so much.

Ellen: And the second thing that I wanted to say before we get started is that this will be our final episode of 2019. We will be taking a couple of weeks off. We are blessed with a large and beautiful family and we have many obligations to attend to as Christmas comes up. So we're going to be taking a couple of weeks off, there will be no new episode for the rest of the year and we'll be back with- our next new episode will go up on Wednesday, January 1st of 2020. So, darling, what animal do you have for us this week?

Christian: This week, I have a recently in-demand bird.

Ellen: Yeah, you guys are going nuts for this bird.

Christian: The Inca tern.

Ellen: I love this friend.

Christian: Scientific name: Larosterna inca. The species was submitted by Dalton Weeks.

Ellen: And also, I think, Dustin Barnett.

Christian: So yes. Thank you all for submitting this species. Today, I'm pulling my information from three sources. First, the Jacksonville Zoo, specifically their website found at jacksonvillezoo.org.

Ellen: Woo woo! That's our zoo. That's our home zoo.

Christian: It is. Secondly, the National Aviary, which is found in Pittsburgh, Pennsylvania, and their website is at aviary.org. And finally, an interesting pull, the National Museum of American History, part of the Smithsonian.

Ellen: Okay....

Christian: Found at americanhistory.si.edu.

Ellen: Okay. I'll be eagerly awaiting our history lesson.

Christian: Yes, me too.

Ellen: Oh no. Why did you say that so deviously?

Christian: You'll see. So first up, I'll save the physical description of this bird mostly for the aesthetic section...

Ellen: [whispers] it's so good.

Christian: So, unfortunately I couldn't find a whole lot of technical details on this particular species. When I'm talking about adult size, I'm going to say pigeon sized.

Ellen: How many chickens is that?

Christian: Three quarters.

Ellen: We have really been slacking on our chicken measurements.

Christian: It kinda depends, right? Is it one of those buffed up Tyson chickens or...?

Ellen: No.

Christian: That chicken lifts. So this bird, the Inca tern can be found and the Pacific coast of South America, from northern Peru to central Chile.

Ellen: I'm assuming that's where the name Inca tern comes from.

Christian: I assume the same.

Ellen: Like, the areas populated by the Incan people.

Christian: Yeah. They belong to the taxonomic family Laridae. Other things that belong to that family are gulls, terns and skimmers.

Ellen: Gulls?

Christian: Yes. So the Inca tern is a seabird.

Ellen: Okay. I didn't know that. That's pretty cool.

Christian: Yeah.

Ellen: But now that I'm thinking of it, I can see the similarity in the shape of the beak to a gull.

Christian: Yeah. Yeah, so again, I'll talk more about this later, but one of the most unique identifiers of this species is this mustache.

Ellen: I love it.

Christian: Uh, so yeah, we talked about how it lives off the coast of South America and these are mostly on sea-adjacent areas like cliffs and islands and that sort of thing.

Ellen: Sure.

Christian: I'll dive right into our first category of effectiveness. How well do they do the things they do? I'm giving the Inca tern a 7 out of 10. They catch their prey, which includes small fish like anchovies and crustaceans, by diving and dipping into the water.

Ellen: Oh, they're divers.

Christian: Yes.

Ellen: That's pretty interesting.

Christian: Yeah. They kind of have that streamlined look, and you'll also notice they have webbed feet.

Ellen: That they do.

Christian: Yeah. So they're pretty good at that, catching their food that way. They flock by the thousands when feeding sometimes.

Ellen: Woah. I would love to see a big flock of these big pretty boys.

Christian: Ingenuity, I'm giving a 6 out of 10, primarily because they often follow fishing boats and surfacing sea lions looking for scraps.

Ellen: Oh, so they're a little resourceful.

Christian: Yeah. So you can see this with regular gulls, where there's a shrimp boat or a small fishing boat near shore, you'll see a bunch of birds flying around trying to... Being opportunistic.

Ellen: Are they as insistently annoying as seagulls?

Christian: I can only assume, yeah.

Ellen: We live in Jacksonville, Florida, which is very close to a beach, and the seagulls are less than kind.

Christian: Yeah. Don't feed them.

Ellen: They have a reputation. Well, you don't have to feed them.

Christian: They feed themselves.

Ellen: If you have food on the beach, they're going to get it. You don't have to give it to them.

Christian: Another point I'm giving them for ingenuity is when they're nesting, they'll sometimes use abandoned Humboldt penguin nests.

Ellen: Okay.

Christian: Yeah. So they live in the same area as those penguins.

Ellen: Huh. How far South is that?

Christian: Well, keep in mind how far south Chile goes.

Ellen: It does go way down there. It starts to approach like, Antarctica.

Christian: Yup. But these are still penguins that are found in relatively warmer climates.

Ellen: Right. Okay. So yeah, I guess I was thinking of them being more like tropical, like warm climate birds. But then you said penguins and I was like, oh!

Christian: Yeah, I guess these are the penguins that are more used to being on land and rock rather than ice.

Ellen: Sure. That makes sense. Cause you also said that they're living on like cliffs and stuff, so. Okay, interesting. I hadn't thought of that being an overlap.

Christian: Yeah. And moving on to the final category of aesthetics, pretty self explanatory, I'm giving a full 10 out of 10 for aesthetics.

Ellen: Oh, they're so good. They're the best ones.

Christian: Yes. So earlier I mentioned they're mustachioed, and I'll give a general description for those that haven't seen a picture, although I suppose you will see a picture when clicking this episode.

Ellen: I'm going to put the best picture I can find as the episode cover.

Christian: They have gray feathers, they have red webbed feet and their beak is also red. They have white tipped wings and their mustache is white. And also they have a little splash of yellow coloration under that mustache.

Ellen: And the mustache is incredibly well defined.

Christian: Yeah!

Ellen: It is like an iconic, very well defined handlebar.

Christian: Yeah. And from my understanding, it's specialized feathers in some way. So that's my general ratings. The meat of this animal comes in it's fun facts, I think.

Ellen: Oh, that's my favorite.

Christian: So first I'll mention their conservation status. On the IUCN, they're listed as Near Threatened, with population trend decreasing. So, their population kind of comes and goes with El Niño so that affects their, like where they're at at any given time cause they're following the food basically. And next I'd like to talk about the reproduction just a little bit. Their courtship displays occur in midair.

Ellen: What!

Christian: Yes.

Ellen: Oh my gosh.

Christian: And then they lay one to two speckled, coffee-colored eggs.

Ellen: Oh, I love that.

Christian: Yeah. I bet they're really cute. Now, my favorite thing.

Ellen: Let's hear it.

Christian: So one of the places that they're often found are known as guano islands.

Ellen: Oh no... Oh, gross.

Christian: So, this describes any island where sea birds are often found, so much so that they have a buildup of guano, which for those unaware, guano is the droppings of sea birds and bats are also described that way too.

Ellen: I feel like "guano" I usually hear in reference to bats.

Christian: Yep. I think something that made that popular was Ace Ventura. One of the Ace Ventura movies.

Ellen: You want to know something? I've never seen an Ace Ventura movie. I'm so sorry.

Christian: I highly suggest them. Or sorry, I highly recommend them.

Ellen: Okay, maybe we'll watch them together.

Christian: You know what? That might be in hindsight, though. It's been years and years and years since I've seen them. We'll see.

Ellen: We'll see how they hold up.

Christian: All right, so here's where this comes into play. This sent me on a, kind of a rabbit hole of what guano islands are all about. And what happened was the Western cultures started realizing how it's good as a fertilizer. So the native people of South America had been using him as fertilizer for a long, long, long time, and actually in the 1500's the Spaniards saw this and they were just like, "no, that's gross." And then they, they didn't do anything with it.

Ellen: That's hilarious to me that they saw them using like, one of the most potent fertilizers that naturally occurs in massive quantities and is completely free and they saw this like, incredibly innovative and useful technique and they were like, "Oh nasty. Let's not."

Christian: So hundreds of years later, in the mid 19th century, the U.S. had an insatiable appetite for guano to enrich its worn out crop soils.

Ellen: Please don't phrase that sentence that way. Please don't lead with the U.S. having an insatiable appetite for guano. Don't say it that way.

Christian: It is uh, validated because our 13th president Millard Fillmore, in his 1850 State of the Union Address, part of it included this, and I quote...

Ellen: This is a way weirder pull than I thought we were going to get.

Christian: So this is where the U.S. history comes in: "Peruvian guano has become so desirable and article to the agricultural interest of the United States that it is the duty of the govern... [laughter] It is the duty of the government to employ all the means properly in its power for the purpose of causing that article to be imported into the country at a reasonable price. Nothing will be omitted on my part toward accomplishing this desirable end. I am persuaded that in removing any restraints on this traffic, the Peruvian government will promote its own best interests, while it will afford a proof of a friendly disposition toward this country, which will be duly appreciated."

Ellen: It is the what of this country?

Christian: It is the DUTY of this country.

Ellen: [laughing] We are grown adults, both of us. We have cars and mortgages.

Christian: So this leads to the Guano Islands Act of 1856.

Ellen: That shouldn't have an act.

Christian: It did, which it came about for the sake of sea bird droppings, used as a powerful fertilizer such that the U.S. Congress authorized our nation's earliest significant expansion beyond the continent.

Ellen: Okay.

Christian: So prior to this we had been mainly expanding in the continental, what is now the United States.

Ellen: Okay. So I didn't think Inca terns were going to play that integral of a role into our...

Christian: So not just Inca terns, it's other seabirds. But I thought this was an interesting connection.

Ellen: That is.

Christian: So, yeah. And a quote from the National Museum of American History, you know: "the Guano Islands Act stated that any guano islands and claimed or unoccupied by others could be claimed and mined, and the guano delivered to the United States at a low price for the benefit of its citizens. This act authorized our nation's earliest significant annexations of lands beyond the continent." So we know this went on later. Right? Cause we have even a state now that's not part of the continent, and other territories and such. So I'm not saying all of our non-continent territories were because of guano, but it just so happened to be the first ones we got were because of guano.

Ellen: That's hilarious.

Christian: Yes. The boom didn't last for long, cause I think with a combination of the industrial revolution and because of improvements in how synthesized fertilizer was coming along, it wasn't needed anymore. But also a problem with sending a bunch of ships and people to collect guano is that you scare away the birds.

Ellen: Oh, yeah that's true. And then they will poop their less.

Christian: Correct.

Ellen: Hmm. Interesting. That's a delicate balance that you have to navigate.

Christian: One that I'm sure the native peoples of South America were able to do, but of course with something like this at that magnitude, it's easy to just go in and wreck things.

Ellen: Well, yeah, I mean when you're pulling up to Guano Island with a big old boat.

Christian: Yeah, several boats. It's lots. The Inca tern.

Ellen: That took some tangents I wasn't expecting, but you know what? That's what we're all here for. So, nicely done babe. Thank you very much.

Christian: Any time.

Ellen: This feels like one of those situations where when you're in school and you have an essay that you're supposed to write, and you have a prompt for the essay and you kind of start off following the prompt, and then like about two paragraphs in, you start writing an essay about a completely different topic and you just stray so far from the topic that like, it's no longer the same essay.

Christian: Yeah, yeah.

Ellen: It's very good. I know so much more about the history of bird poop than I did 20 minutes ago.

Christian: I thought it was interesting.

Ellen: It is. You're right. Before we move on to my animal, I want to take a quick second to thank our patrons on Patreon. We've got Briana Feinberg, Krystina Sanders, the Jungle Gym Queen, Jacob Jones, and Ashley Tucker. Thanks y'all!

Christian: Thank you so much. Alright hun, what animal do you have for us this week?

Ellen: This week I'm talking about the European eel.

Christian: Real eel?

Ellen: This is a real life eel. This is a legit one because...

Christian: Ree-eel.

Ellen: You ever go fishing and you reel in a real eel?

Christian: Oh, jeez. All right, tell me about this eel.

Ellen: Okay, so first of all, scientific name is Anguilla anguilla, and I'm pretty sure that's how you pronounce it [ang-WILL-a]. I looked it up to make sure, because I looked at it and it's spelled like maybe it would be a Spanish word. And you know, we're from Florida where we have a lot of exposure to the Spanish language. And my assumption was that it would be pronounced "ahn-GEE-ya" cause that's how it looks like it's pronounced. But then I found out that it actually comes from the Latin word for eel, and that's not how they do Latin. So the best I could find was Anguilla anguilla, so I'm really doing my best here. So this species was not requested per se, but it was inspired by a tweet that I saw from one of my favorite Twitter accounts, the handle is @FunEelFacts and it's just really fun, and I enjoy seeing a lot of stuff about not only eels but also like knife fish and lung fish and stuff like that.

Christian: Something about those and Twitter. Right?

Ellen: There is a heavy eel presence on Twitter. There's a lot of eel appreciation on Twitter, yes. I've learned a lot about it. But so I'm getting my information on the European eel from the University of Michigan's Animal Diversity Web, love them, and also the European Eel Foundation, which can be found at europeaneel.com.

Christian: Okay.

Ellen: So, the adult size for the European eel females are actually larger than the males, so females can be up to 65 centimeters or 2 feet long, and males up to 40 centimeters or 16 inches long, and that is at their kind of maximum size. Their location, you know, they're called the European eel, but um, they're not always there. So their location kind of depends on where they're at in their lifecycle. So stay tuned, we'll- TBA. We'll come back to that.

Christian: Alright.

Ellen: Their taxonomic family is called Anguillidae, this is the family of the freshwater eels. So way back in episode 2, you talked about the electric eel, which you revealed to us is not actually an eel.

Christian: Correct.

Ellen: It's just long and snake-shaped, so they called it an eel. And the electric eel is a knifefish, that you mentioned way back when. So this is a real life eel. This is an actual one. So true eels belong to the order Anguilliformes. Now they're their freshwater eels, but not 100% freshwater eels. This is really cool. So to get into my ratings, first rating up is effectiveness. And for effectiveness, I give them an 8 out of 10. So, since eels don't have pelvic fins to propel them through the water, you know their upper and lower fins are all fused together, right? To make this one sort of ribbon-shaped fin that goes all the way down the body. So eels swim by undulating their body in a wave shape and the wave sort of rolls down their body. So it's not only really neat to watch, it's a little bit hypnotic almost, but it also allows them to swim backwards.

Christian: Woah!

Ellen: Yeah. Not a lot of fish can swim backwards. There are other fish that are not eels that can do this, but not that many of them. But so eels are a little bit special for their ability to swim backwards.

Christian: Nice.

Ellen: That's pretty cool. So for me, the European eel's biggest effectiveness factor is its hardiness. So they can survive and breed in a wide range of temperatures, and they can also regulate the balance of fluids and salts in their body that allow them to live in salty, brackish and fresh water. So this is really important. This is called osmoregulation, and this brings me to the most impressive thing about the European eel: it's lifecycle is nothing short of Herculean. It is absolutely ridiculous. So what's kind of funny is that way back when, Aristotle kind of took a stab at guessing at the eel's lifecycle and his- Aristotle came to the conclusion, after what I'm sure was rigorous study, that the eel was spontaneously generated out of the mud.

Christian: What!

Ellen: Yeah. Just showed up. It just appeared! So close. Not quite though. So the eel larvae are actually already independent when they hatch, and they hatch in this place called the Sargasso sea. And this is a region of the Atlantic ocean, it's pretty close to North America, but it doesn't actually have any land boundaries. So it's a sea, but a sea that's contained completely within the Atlantic ocean.

Christian: Okay.

Ellen: So the European eel is a little bit Pokemon-like in its development in that it goes through these very distinct changes in its physical form as it develops through life. So they're born as these tube-shaped transparent larvae, and then when they get a little bit older, they develop into what's called leptocephalus larvae. They're still see-through, but they're kind of like a leaf, where they're sort of vertically flat. You know what I mean? Like, like how the eel has that sort of ribbon shape, but it tapers to a point at the end, so it looks kind of like a leaf or maybe a long piece of seaweed. And in that state, they're still transparent so you can see all their bones and it's a little bit spooky. But so they stay in this stage for about a year, and in this stage they drift along ocean currents and the ocean currents carry them all the way over to like, Europe and Northern Africa.

Christian: Wow.

Ellen: And then once they're there, they metamorphose into glass eels. So this is what you'll hear them kind of referred to as most often, but it just refers to a specific stage in their development. Glass eels, where they're tube-shaped, they have that kind of like iconic eel shape, and they're still transparent at that point. So from here they enter into estuaries and freshwater systems, and then once they're in there, their pigmentation changes to a grayish brown color, and at this point they become what are called elvers. So, as elvers they migrate- they migrate upstream, actually into freshwater systems kind of throughout Europe. They can even travel across land for short distances. Yeah. It's a little- kind of gross, but oh well. Like they're, they're going for it. And they will live in fresh water for many, many years before maturing into their final form, which is called the silver eel where their like gray color changes to more shimmery silver. And in this form, they stop feeding completely and they rely on whatever energy they have already stored to carry them through this final phase of their life. And this is when the eel travels back down stream out of the freshwater systems it's been living in and growing in and it crosses the Atlantic ocean again and returns to the Sargasso sea.

Christian: Wow!

Ellen: Yes.

Christian: That's quite the journey.

Ellen: Yes. So it's come all the way over from like, close to- almost like, close to the Caribbean all the way over to Europe and then turned around and came back.

Christian: That's intense.

Ellen: It's crazy. And then it gets crazier when you find that they only breed once in their entire lifetime, laying one clutch of eggs. So being closely related to Japanese eels, Japanese eels lay between 2 and 10 million eggs at a time.

Christian: Wow.

Ellen: Yes. So nobody's actually seen the European eel lay its eggs, so nobody has a good number on how many it lays at a time. Apparently this area of the ocean is very, very difficult to monitor because there are like no structures in that area. There's no landmarks or anything. It's very difficult to keep track of anything in this area of the ocean. So nobody's actually seen them lay eggs, so nobody knows for sure how many they lay at a time. But we can guess that it's in the millions because that's how Japanese eels do it and they're closely related.

Christian: Wow.

Ellen: Yeah, so the female comes out there and she lays her millions of eggs and then she dies. That's it. End of life. She just lays the one clutch of eggs. And they do that thing where they will, the females just lay the eggs and then they die, and then the male comes along and fertilizes them. So they don't necessarily mate. Right? They just lay the eggs.

Christian: I think we see this with some species of fish, like salmon and that kind of thing.

Ellen: It's a common thing for fish. Yeah. This is how they do. So obviously the larvae have to be self-sufficient when they hatch because there's nobody there to take care of them or protect them or anything.

Christian: And this happens in that special part of the Atlantic?

Ellen: Yes.

Ellen: Okay.

Ellen: So like this all obviously very impressive, right? They've gotta be pretty tough to be able to withstand that kind of journey. I deducted a few points for the fact that they've pretty much bumped up their difficulty settings on life. Like they're like, playing on legendary mode for like no reason.

Christian: I'm gonna be a fish, but like, Nuzlocke challenge.

Ellen: They're traveling thousands and thousands of miles to reproduce, they immediately die once they reproduce. So they've only got just that one shot, and then the whole thing of just being done with eating, once they become adults, they're like, that's it. I don't need to eat anymore. Which makes me think of like moths, how a lot of moths will do this. Like the luna moth is one example I can think of where like, once it reaches its adult form, it's just done eating. It's like, sorry, I only have one goal now that because they don't have the parts to eat anymore.

Christian: I think that with the Luna moth they just lose their mouth entirely.

Ellen: Yeah. But so I just thought that- I just think that's just so extra. Why are y'all doing the most like that? Moving on to ingenuity, I give them a 5 out of 10 for ingenuity. So their migratory path is about 5,000 kilometers, or 3000 miles long. That's a lot. And the eel is only like a maximum of two feet long. So that is a lot of ground to cover for this little dude. So that made me think, how does it know where to go? How does it know how to get back to where it needs to go and like, how does it keep coming back to the same- not the same exact spot, but how does it keep coming back to the same area? So, according to a research article that I found titled "Glass eels have a magnetic compass linked to the tidal cycle," and this was in Science Advances in June of 2017, so what they found was that the eel orients itself in the water in alignment with magnetic fields both in the sea and also in laboratory settings.

Christian: Wow!

Ellen: Yeah. So that kind of shows that they can both detect magnetic fields and that that is what they're using to determine what direction to go. In. Another study that I found, a 2016 study showed that not all of the eels take the same path or travel at the same speeds. They kind of find their own way there with a lot of variety. So some of them go in just very, very different paths than others. And this ends up giving them very staggered arrivals at their breeding destination. So it's not like they all show up at once and breed and then that's the end of it until the next year, it's like they'll show up at different times because they've taken different paths and gone in different speeds.

Christian: Huh.

Ellen: Yeah. But if they don't show up within the right season and the water is not the right temperature, then they'll just stay there and they have to wait for the next breeding season.

Christian: Huh.

Ellen: Yeah. So it's kind of thought that this variation in their migratory paths gives them better chances of actually making it to the sea.

Christian: Yeah. Cause if there was like, I don't know, a couple of weeks every year where there's just millions of eels coming around, there would be animals waiting, right? To eat them.

Ellen: Sure. Like maybe it makes them a little bit harder to catch or it just like gives them a better chance of survival. But yeah, it's not like every single- it's not like you'll see like, butterflies or certain types of birds or something where they have a very, very specific and exact route that they'll take consistently. Eels are kind of going their own way. The eels are a little bit more independent than that. Another point that I gave it for ingenuity was that they burrow into the mud to hide during the day and they come out to feed at night. And they can also burrow in sand and hide under rocks to escape predators, which I think probably is why Aristotle thought that they were like, created in the mud, but he thought that this was like, a spontaneous generation thing and that they just are birthed into being by the mud. Like a mud golem or something that's just born of mud.

Christian: I was about to say, it kind of reminds me of a Lord of the Rings thing where they were talking about how drawers were born.

Ellen: Yeah, I so I guess that's what he thought was going on with eels, but not the case. Which it kind of makes sense that he would think that having never seen them, like breed and spawn and stuff cause they're doing it in the middle of the Atlantic ocean.

Christian: I guess?

Ellen: So it kind of makes sense cause he's never seen them hatch or anything because he would have only ever seen them in that like juvenile form. So I guess you can't fault him too much for coming up with wild guesses. But still, it's funny, I'm going to dunk on him anyway. So another thing that the European eel will do is they'll hibernate during the winter. So they go into an inactive state called torpor when temperatures start to drop and they'll actually burrow into the mud and they'll go into the state of torpor and they'll wait until- cause a lot of times during these colder seasons, like river beds will dry up and stuff, so they'll, they'll wait until the water comes back.

Christian: That's interesting.

Ellen: Yeah. It's a cool way for them to conserve energy until things warm back.

Christian: Is this eaten? Like by people?

Ellen: Yes, very much so. That's in my- that's in a later thing.

Christian: Okay.

Ellen: So, uh, last category for the European eel is aesthetics. I give them a seven...? Seven. Seven out of 10. They have a cute, rounded, snake-like face. If you look at their face, it kind of looks like a Python, like a ball python's face a little bit to me. I think it's pretty cute. Um, and also the leaf shape of their leptocephalus stage is really, really cute. It's, it's just a really pleasant, like pointed leaf shape. I think it's adorable. But other than that, not a lot going on in the looks department. Right? Nothing's super special about them. They're very much like, kind of your standard-issue starter kit eel. It's just, it's an eel y'all. I dunno what else to tell ya. So to wrap up with some miscellaneous information, this was kind of why I wanted to talk about this eel. Their conservation status is critically endangered.

Christian: Really?

Ellen: Yes. They are doing very, very badly. Actually, not too long ago, their what's called their recruitment rate, which is the amount of baby eels that were being hatched, was as low as 1% of what it had been in the '80s.

Christian: Wow...

Ellen: Yes. So their numbers were just absolutely abysmal. They were in the garbage can. So some of the greatest threats to European eels, according to the IUCN, include barriers to migration, so structures like hydropower turbines and water pumping stations in Europe.

Christian: Yeah...

Ellen: Yeah. So this can cut off the eels from being able to travel freely to and from the ocean.

Christian: Oh...

Ellen: Yeah. So they could like not be able to get into the rivers and stuff that they normally need to get into because of these barriers. There's also, of course, degradation and loss of habitat and pollution causing metabolic disruption to the eels. You know, cause they're absorbing a lot of that into their body, including- this is wild, I'm not going to go too deep into it, but I just wanted to put it out there: illicit substances such as cocaine in the rivers that they, you know, live in. So... Sorry about the coked up meals. But...

Christian: Man.

Ellen: Yeah, other things- I have so many things. Another thing is a changing oceanic conditions influence the currents that have to carry the eel larvae in from the sea. Right? Like that's what they're using to get into these freshwater systems, and when the currents change, they're not getting to where they need to go so they can't develop. So that's just- and then finally, overfishing in places where European eels are caught to be eaten. Since the European eel has to travel over such huge distances and it has to be, you know, shifting between saltwater and freshwater and it's just, it's so demanding and its needs, they've never been successfully raised in captivity. So, if you're going to eat them, you have to catch them from the wild. So conservation efforts have been put in place trying to raise eel numbers, and one of those efforts was a ban on the exportation of the European eel and that was put in place by the EU in 2010. So it's now illegal to export European eels from the EU.

Christian: So I know you're not a fan of eating fish in general.

Ellen: Yeah, I don't eat seafood at all. So this is all equally gross to me.

Christian: But to me, I've had eel plenty of times, but it's always been in the same context, and that is sushi, or Japanese food in general.

Ellen: Sure.

Christian: Very tasty in my opinion. But I'm wondering what species is that normally?

Ellen: I don't know what like kind it- what is it, unagi? Is like the word that they use for eel that they put in sushi? But so, I thought this was interesting. Another conservation effort for the European eel has included trapping the juvenile eels and then transporting them where they need to go. So like, kind of helping them navigate around those barriers that are keeping them from migrating, like they'll go out and like, say there's eels that are trying to get like into a river but they can't get through because there's like, I don't know, a water station or something. They'll like, go trap the juvenile eels, put them in a bunch of coolers I guess, I dunno, coolers and tanks and stuff, and they'll actually transport them over land and take them to where they're trying to get and then set them free. Kinda like human bridging them. Which I thought was a neat idea that that was pretty cool.

Christian: Whatever works.

Ellen: Yeah. And also the activity of fisheries that catch wild eels has been severely limited. So now they say that you have to leave at least 60% of the wild eels in the wild in order to have enough to replenish the population.

Christian: Huh.

Ellen: Yeah. So my last little fun fact I want to include in here is a fun history fact that I learned from John Wyatt Greenlee's website HistoriaCartarum.org, and what I learned from this is that documentation from medieval England records taxes from territories being paid to royalty including massive numbers of eels. Say you were, you know, a landowner and there was royalty that you needed to pay taxes to, your taxes wouldn't necessarily be like an amount of gold or coins. It would maybe be like you know, 50 apples, 30 pounds of carrots, 300 eels. So like, eels used to be sort of used as a bit of currency and that was recorded in Europe all the way up until like, the Middle Ages.

Christian: Wow.

Ellen: Yeah, it fell out of fashion to eat eels in Europe at least. It kind of became less popular over time. Like, eels became less of a desirable food item, and then I feel like they kind of fell out of cultural relevance because people weren't eating them, so people weren't really thinking about them. You know? Like I feel like when I, even before I learned all of this stuff about the European eel, I felt like, you know, when you told me that the electric eel was actually a knife fish, I realized that I actually knew literally nothing about eels because that was the one I thought I knew anything about. And it ended up not being an eel. But so yeah, I was just really happy to get to learn a lot more about eels in general. And I thought they were really cool. And this one is really neat and I had no idea that it was so critically endangered, but it is. And so it was really interesting to learn about.

Christian: That's awesome. Thank you honey.

Ellen: No problem. Thank you. Oookay, that's all we have for this week, so thank you everybody that's joined us this week and in all previous weeks. We have seen like, a lot of growth recently and that's been really great. So I am really happy for all the new people that have been joining us.

Christian: Yeah. Thanks everyone.

Ellen: Thank you everybody.

Christian: Happy holidays, and have a happy new year.

Ellen: Yes. We'll see y'all in 2020. That is a wrap on 2019.

Christian: I was going to make it 2020 vision joke, but I decided not.

Ellen: Do you have to?

Christian: Nope. Bye everyone!

Ellen: Bye!

30: Blue Footed Booby & Dingo

Ellen: Hey friends, this is Ellen Weatherford.

Christian: And this is Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast.

Christian: Yes. Where we talk about animals that you suggest and give them a rating of... zero to 10. I don't know if we've done zeros yet.

Ellen: Not quite yet. We've got some ones.

Christian: I'm gonna say zero to 10, in three categories: effectiveness, ingenuity and aesthetics.

Ellen: We are not zoological experts. What we are experts in is...

Christian: Hugs!

Ellen: Licensed and certified.

Christian: Yup.

Ellen: The only announcement I have right now is that next week is our live show, so if you're listening to this in or near the Jacksonville area, come listen to us learn you about aminals. If you want to. That would be fun.

Christian: In the picturesque setting of Riverside, Jacksonville.

Ellen: Yeah, it's so it's called Cultivate and it's a really, really cool little space down in the Riverside area. It's very adorable and I'm really excited to be there and see all of your beautiful faces.

Christian: All right, so who's first this week?

Ellen: You are.

Christian: Meeeee?

Ellen: Yes, you. It's your turn.

Christian: This week, I bring you and our listeners a very good bird known as the blue-footed booby.

Ellen: Spectacular.

Christian: Yes. That's not its scientific name. Its scientific name is actually Sula nebouxii.

Ellen: Interesting.

Christian: That's how I choose to pronounce it.

Ellen: Sounds great.

Christian: This species was submitted to us by the Paudeville podcast, as well as Katie Johns.

Ellen: Thanks y'all.

Christian: Thank you so much.

Ellen: Thank you for subjecting me to this.

Christian: Here we go. I'm getting my information from National Geographic, found at nationalgeographic.com, as well as Animal Diversity Web, found at animaldiversity.org. This is a seafaring bird mostly. I'm going to describe what it looks like really quick.

Ellen: Please do.

Christian: So, as its name implies, they have blue feet, which are also webbed. They have brown feathers on their wings, white feathers on the breast. They have brown and white feathers on their head, back, and tail. Their face and bill is a grayish blue, and they have the round head when you look at them from pretty much any angle.

Ellen: The blue feet are like a very, very vibrant blue, too. It's unexpected. When you see the rest of the bird, the rest of the bird has kind of regular, kind of muted... Normal bird colors, and then you get to the feet and it pops off.

Christian: Yeah. And these are adults that had the blue feet, by the way. As juveniles, they do not have that coloration of feet.

Ellen: They look kind of like duck feet too, right?

Christian: Yeah, they're webbed. They're very good at pushing water. Let's talk about how big they are. So they are 32 to 34 inches long, or 81 to 86 centimeters. Their wingspan is almost five feet, or about one and a half meters, and they weigh 3.25 pounds, or one and a half kilograms. Let's talk about where you can find these guys. They are off the western coasts of central and South America, but half of all breeding are found on the Galapagos islands. So a lot of the times you'll hear about these in documentaries that are centered around the Galapagos islands. Taxonomic family is Sulidae. The other things in that family are birds called gannets, as well as other boobies. So there are several birds known as boobies, but they have different colored feet in features. I think there are six.

Ellen: Interesting. So, and they are really stuck on the name, huh?

Christian: Yep.

Ellen: It can't be changed?

Christian: Spoiler alert: There's a reason for the name.

Ellen: Oh!

Christian: It's coming.

Ellen: Okay.

Christian: So first category up, we're going to talk about effectiveness. How good do they do the things they do? These are physical adaptations. I'm giving the blue footed booby a 7 seven out of 10. So first of all, webbed feet. They're very, very good at swimming. And they can, they're very good at diving too into the water.

Ellen: Oh really? Like they go fully underwater?

Christian: Yep. So they can plunge into water from a height as high as 80 feet, or 24 meters. That's pretty high up there.

Ellen: How did they get that high up?

Christian: ...Flying?

Ellen: Oh yeah, they're... They're birds. I forgot.

Christian: I guess I didn't explicitly say that, but yes, this is a flighted bird.

Ellen: Okay. Thank you for explicitly stating that.

Christian: But I believe one could deduce that from the wingspan.

Ellen: That's true, that's true.

Christian: So yeah, they're very good at swimming and diving, but they are not great at getting around on land, which is good, because they're only on land when they're nesting at night.

Ellen: I'm imagining a funny waddle.

Christian: Yes, it is very funny. I will touch on that again later. Next category: ingenuity. They do smart things or interesting tactics, tool use, that sort of thing. Gonna give them another 7 out of 10. They will sometimes hunt cooperatively, but usually they're hunting on their own and this is where they're diving under water and catching small fish. Like sardines, that kind of fish.

Ellen: Sure.

Christian: Not unlike penguins except, you know... Buffed, what with flight and all.

Ellen: Well, I mean they live in a warmer climate, right? So they don't have the same needs that a penguin has.

Christian: That's true. I guess that's not fair to penguins.

Ellen: I know we should be- we should be nicer to penguins. Everyone always dunks on penguins for not being able to fly. But like, we talked about the emperor penguin and why they don't fly. Right? They have their reasons. Leave penguins alone! Be nice to penguins.

Christian: My next ingenuity point: my primary one, and this is has to do with their- with the males' mating display. So the males will show off their feet.

Ellen: Really?

Christian: By doing a high-strutting, high step.

Ellen: I'm imagining Rockettes.

Christian: ...What?

Ellen: The Rockettes, like the ladies that do the Can-Can at like, festivals and parades and stuff.

Christian: That's too elegant. Again, imagine a funky waddle. It's like a person trying to walk around with flippers on.

Ellen: Aw, that's pretty great actually. Okay. So the male booby is walking around strutting his stuff and it looks like someone just kind of flapping around in flippers, and the female booby sees this pitiful display and she's like, "Aw yeah, I need to get me some of that."

Christian: So, here's the thing, the bluer the feet, the more attractive.

Ellen: Definitely. Absolutely.

Christian: And here's why. So this is the primary reason why I put this under ingenuity. So it's thought that the foot color indicates being healthy and well fed.

Ellen: Really?

Christian: So that's because the blue coloration comes from their diet.

Ellen: It's reminding me a bit of how flamingos turned pink due to the krill that they eat.

Christian: Yes.

Ellen: Okay.

Christian: And I got this information from a very specific article, which I will now cite. That article is titled "Pigment-based skin colour in the blue-footed booby: an honest signal of current condition used by females to adjust reproductive investment."

Ellen: Adjust reproductive investment.

Christian: Yeah, that's, that's a scientific way of saying having a fondness for blue feet.

Ellen: I know anybody out there using online dating services is probably well familiar with adjusting their reproductive investments.

Christian: So yeah. The thought is, you know, the bluer the feet, the better an indicator that is of the male being healthy, being able to rear healthy young, that sort of thing. Last category, aesthetics. How pretty are they? Again, a 7 out of 10. So this is a 7 out of 10 across the board for me. For the blue footed booby...

Ellen: It's just a, it's just good. It's okay.

Christian: Yeah. Blue feet, obviously aesthetic, but also I find them sleek and a little goofy to look at them head on.

Ellen: Yes! Oh my gosh. There's nothing that makes me laugh harder than seeing a picture of a blue footed booby looking directly at the camera.

Christian: Yes.

Ellen: Because they look so nervous. Don't they? They look so anxious and caught off-guard.

Christian: It kinda reminds me of some of the Muppet characters. A little bit.

Ellen: What's the one that goes, "meep meep meep meep meep meep," who's that?

Christian: I do not know.

Ellen: It's that one!

Christian: Okay. So yeah, 7 out of 10.

Ellen: I feel like the blue foot is very unexpected. Like if you're starting at the top of the animal and you kind of work your way down, you're like, okay, I get it. Long skinny beak, long neck. Okay, brown and white bird. Oh no! You get to the feet and you're like, what happened?

Christian: I find them cute. So, some miscellaneous info. First up, the conservation status: they are of least concern.

Ellen: Oh, that's not what I expected. I don't know why, I guess I expected a seafaring bird to not be doing very well.

Christian: Apparently they're doing fine.

Ellen: Oh. Good on you, boobies.

Christian: Yes. Their average life span in the wild is 17 years. Their babies, earlier I mentioned that their feet are not blue, but also they look like little white floofs.

Ellen: Oh, little cloud bird!

Christian: Yeah, they're pretty cute.

Ellen: Just a little fluff ball.

Christian: And talking about babies, when the parents are feeding their young, so they do the very typical bird thing where they go out and get food, regurgitate it into the baby's mouths. Keep in mind these birds will have about two or three young in a clutch, I guess is what you would call it. So if food is scarce, what they'll do is they will decide to feed the larger of the chicks. As a way of, you know...

Ellen: Picking one.

Christian: Ensuring at least one survives.

Ellen: Readjusting their reproductive investment.

Christian: It's so stone cold.

Ellen: There are so many birds that we've talked about that do this though.

Christian: Yes. I guess it makes sense, I suppose.

Ellen: Birds do tend to spend a lot of their effort and energy caring for their young, right? So if you're going to be putting that much energy into it, you have to kind of allocate it appropriately to make sure that you're kind of getting the best results for your efforts. It's like we talked about the shoebill, that doesn't even bother with the second chick. Right?

Christian: That's true.

Ellen: They are just like, "Oh well, sucks for you."

Christian: Yeah. And also, they keep their eggs warm with their feet. So their feet have increased blood flow, so are warmer than the rest of their bodies.

Ellen: Really?

Christian: Yeah. So they use their feet to keep the eggs warm. I think a lot of birds have what's called a brood patch on their body to do this, but these birds do not.

Ellen: They have brood feet.

Christian: Yes.

Ellen: That's kind of cute. So I haven't seen this happen, but I am imagining a booby just standing on its eggs.

Christian: I don't think it's standing on them. I think it moves the eggs to be on top of its feet, like kind of like a penguin.

Ellen: Oh, that's pretty cute. That's adorable.

Christian: And now, my last and best piece of information: where the name comes from.

Ellen: Yes, please.

Christian: So boobies are thought to be named after the Spanish word for stupid.

Ellen: Oh no! No, no, no.

Christian: Which is "bobo."

Ellen: *sighs*

Christian: Yup. So some things are coming together, right?

Ellen: Yeah.

Christian: Per National Geographic, and I quote...

Ellen: Come on.

Christian: "European colonists may have characterized these clumsy and unwary birds when they saw them on land, their least graceful environment." Second quote, per Animal Diversity Web...

Ellen: Excellent.

Christian: "Its lack of fear and clumsiness on land has made this species vulnerable to man."

Ellen: Its both lack of fear and clumsiness. So I mean, if you're going to be a complete disaster walking around on land, you gotta be confident. Right? You gotta just go for it. Just own that walk.

Christian: Yup. So that's where the name comes from, or is thought to have come from.

Ellen: Delightful.

Christian: I thought it was funny cause I have heard the, the term "bobo" before.

Ellen: At least in the area where we live, people use "bobo" to describe something that is subpar, something that is not great.

Christian: But like just imagine for a moment you're a, you're a Spanish conquistador, you've arrived in Mexico and after having a busy day of doing awful, awful things, you go to the Pacific coast to find these birds and you're just like, "Man, these birds, they stupid."

Ellen: You see them and you're like, "This bird? Nuh-uh, that's bobo. That is a bobo bird." I would imagine that if I was an ancient Spaniard, having just had a long day of conquistadoring, I would probably be delighted to come across a bird just trying its best to get from point A to point B and just flapping its big old feet around. I'd probably be like, now that's great.

Christian: Flap flap honk honk!

Ellen: I am a bird and I'm trying!

Christian: So, that is the blue footed boobie.

Ellen: Excellent. You have really strengthened my connection to this bird. Thank you. Um, how long did you spend looking at pictures of boobies on the internet?

Christian: A good four-ish hours.

Ellen: Great.

Christian: And in this corner...

Ellen: Please don't say how much I weigh.

Christian: I was trying to think of what your animal weighs. I don't know.

Ellen: Weighing in at... An average of about 30 pounds.

Christian: The feather feather feather weight.

Ellen: But it ain't got no feathers. It's a Dingo!

Christian: Yay!

Ellen: Scientific name... Is... In a little bit of a gray area! It's a little bit controversial what their scientific name is.

Christian: Interesting.

Ellen: They go by either Canis dingo or Canis lupus dingo or Canis familiaris dingo.

Christian: So what has caused this drama in the scientific taxonomic arena?

Ellen: It is off the chain. There's so much, but there's reason for the drama.

Christian: Okay.

Ellen: It's legit. It's for real. It has real world implications. So this is a situation where taxonomy is very complicated and very heated, but for good, legit reasons. First of all, the species was submitted via Instagram by the Tails Waggin Camp, which is the dog boarding camp where we send Puppy when we go out of town. Yeah. So I'm getting my information on the dingo from the Australian Museum as well as the Australian Dingo Foundation. If you have never seen a dingo, it's a dog... And that's it. It's just a dog. It's just a dog. It's about two feet tall, or 62 centimeters at the shoulder. And like I said earlier, about 30 pounds. It's like a medium-sized dog. Medium, maybe a little bit on the larger size typically, but it's a tall dog.

Christian: Sure.

Ellen: So they are found in Australia. Now here's the thing, the earliest evidence of dingoes in Australia dates back to 3,500 years ago.

Christian: So they did not come with the Europeans.

Ellen: No, definitely didn't come with Europeans, but they also weren't always there.

Christian: Okay.

Ellen: This is a relatively recent addition to Australia. So it's believed that they were introduced to the continent prior to that evidence. It was the only hard evidence that could be found and dated back to 3,500 years ago.

Christian: Okay.

Ellen: They were probably introduced to Australia around 5,000 years ago. So in the grand scheme of things, that's very recent. Right? But numbers on that vary a lot. Like, I found so many different sources that said so many different things on how long dingoes have been in Australia. So some of them said 5,000, some of them said 10,000 or 12,000, so just something around that amount of time.

Christian: Sure.

Ellen: They've been there for a long time, but not as long as native species. So it's generally believed that the dingoes were brought onto the continent by people from Southeastern Asia. Some genetic evidence suggests that they were most likely hunter-gatherers from Sulawesi in Indonesia.

Christian: Okay.

Ellen: They believe that because the Dingo doesn't have the ability to digest grains, which suggests that it was not domesticated by people who were using agriculture. To, you know, so like if a dog had been domesticated by people that were harvesting grains or rice or something like that, they probably would be feeding those greens and rice to the dogs, and the dogs would have developed the ability to digest those things over time.

Christian: Okay.

Ellen: So you see this in more recent domesticated dog breeds, you see the ability to digest grains but dingoes can't at all. Yeah. So that suggests that the people that they accompanied weren't harvesting grains.

Christian: Interesting.

Ellen: Yeah. So that's why they think they were hunter gatherers. The dingoes also had a very, very narrow origin suggesting that it took very, very few dingoes to establish the population. So they think that only like, a couple of dingoes came over.

Christian: Wow.

Ellen: They said it could have been as few as one breeding pair. So their taxonomic genus is Canis. This is the same genus as dogs, wolves and coyotes. Dingoes have been shown by genetic studies to be more closely related to modern domesticated dogs than to gray wolves.

Christian: Make sense.

Ellen: Yeah. So you can see the strong similarity with domestic dogs, particularly in shiba inus and akitas. They look like, exactly the same. Right? Except shiba inus are like, kind of cuter. They're like little tiny dingoes with little curly hair- little curly tails and, but it looks a lot like a dingo. Right? You can definitely see the similarity there.

Christian: Sure.

Ellen: So they likely share a common ancestor from Southern China. So it's thought that like some of those Japanese breeds of dogs share an ancestor with dingoes.

Christian: Okay.

Ellen: There's still a lot of ongoing debate surrounding whether dingoes are actually their own species or they're just a breed of dog. This has implications when you get regulating, like protecting them or not protecting them as a species, whether they count as a species or whether they're just a breed of like, feral dog essentially.

Christian: Gotcha.

Ellen: Now they are most closely related to the New Guinea singing dog. So one was likely the origin of the other, because they're so closely related, and there actually used to be a land bridge connecting Australia and New Guinea.

Christian: Oh.

Ellen: So around the same time that the dingoes and the New Guinea singing dogs appeared in those areas, there was a land bridge between the two, but it's not really clear which one came first.

Christian: Quick question.

Ellen: What?

Christian: The new Guinea singing dog.

Ellen: Yes. It's very cute.

Christian: Why is it known as this?

Ellen: Because it howls in a really cute way, and it has a very melodic howl.

Christian: Is this a common breed?

Ellen: It's very rare.

Christian: Were you aware of it prior to doing this research?

Ellen: Yeah, I think I showed you videos of them before.

Christian: Okay.

Ellen: They have a really pleasant howl. It's really nice.

Christian: I'll have to look them up.

Ellen: They're very, very rare though. But it's not really clear whether these dogs showed up in Australia first or New Guinea first. So I'm going to get into my ratings. I use the same system as Christian. I'm going to start with effectiveness. Our physical adaptations, I'm giving the Dingo an 8 out of 10.

Christian: Okay.

Ellen: So first of all I'm going to talk about their fur. Their fur gives them a pretty decent amount of camouflage. So the fur is typically like a golden yellow or a tan color that blends in with the colors of a desert, right? It's going to blend in with a lot of like, the sand and dead plants and stuff like that. But, since they're found in all these different areas of Australia, Australia has a lot of different biomes. Right? So there could be some areas with desert, some areas with forests, some with like, wetlands, like there's just a lot of diversity there. So there are actually different types of dingoes with coats that are more adapted to the area where they live.

Christian: Neat!

Ellen: Yeah. So there's three types of dingoes. There's the desert, the alpine and the northern dingo. So in more forested areas, dingoes actually tend to have darker fur and they can be black. And what's really cute is that the dingoes that are black have white markings on them, looks exactly like a shiba inu. You know like a black and tan shiba inu? It looks exactly like that.

Christian: Neat.

Ellen: Yeah. So, differences between the dingo and the dog. Dingoes have longer teeth than modern domesticated dogs. They're also built for long distance running. So they have a really, really slender body. They have these long, super muscular legs, so they're really good at running and they're very fast. So it's good for covering long distances in like, you know, the outback and stuff where they have to- they have very large territories, so they have to cover really long distances and they're really built for that. They're definitely runners. That brings us to ingenuity. I give the dingo a 9 out of 10 for ingenuity.

Christian: Wow.

Ellen: So they will often hunt in packs. They communicate with each other with howls and with other vocalizations, like growling. They're working together and communicating with each other to take down prey that could be bigger than them.

Christian: Right.

Ellen: There have actually been a few studies testing dingoes on their intelligence.

Christian: Oh?

Ellen: The first study that I wanted to take a look at was their ability to take social cues from humans. So, like I mentioned earlier, they came to Australia with humans. It doesn't necessarily mean that they were completely domesticated, just that they hung around with humans a lot. So they at least spent, you know, a good chunk of their development around humans, but then returned to the wild. So it's interesting. They're kind of right in that midway point between a dog and a wild, like wolf or something.

Christian: Okay.

Ellen: So, there was a test where they tried to see how well dingoes could comprehend human gestures. So these are things like looking at a target, pointing at a target to see if the dingo would pick the correct one. These were like, containers with food hidden inside. So they had already tested domesticated dogs and wolves using the same methods. So they just kind of applied the same test to dingoes to see how they fared. Pure dingoes, when tested for comprehension of these gestures, scored better than wolves, but not as well as domesticated dogs.

Christian: Expected.

Ellen: That makes sense, right? They're a little better at understanding people than wolves, but not quite as good as a pure dog. So another interesting thing about dingoes in relation to humans is that dingoes also initiate eye contact with humans more often than wolves. Wolves typically would not make eye contact with the human... Like, super willingly, but the dingoes maintained their eye contact for shorter durations than dogs.

Christian: Okay.

Ellen: It's just another example of them being like, kind of in that midway point between being, you know, completely wild and a little bit more domesticated.

Christian: Right.

Ellen: Now there was another test of their intelligence called the detour task. This is a test of their problem solving abilities in which a food reward is placed behind a transparent barrier, in this case, it was a chain link fence, that the subject has to navigate around in order to access the food roared. And in this case for this test, it was shaped like a V with the food in the corner and the dingo on the other side where in order to get to the food, which the dingo could see and smell, the dingo would have to go all the way around one of the sides. And it would have to stay focused on the food long enough to go all the way around the fence and then come back to where it knew the food was.

Christian: Okay.

Ellen: This test was actually kind of the reverse of the earlier test, where domesticated dogs perform pretty poorly on this test. They do a bad job, they tend to get more frustrated by having to problem solve independently without relying on, you know, interpreting cues from a human. They will tend to like, maybe start trying to dig at the barrier or they'll just bark at it or something, like, they- domesticated dogs tend to do very poorly at this task, but wolves are like 100%. Wolves ace this, no problem. And dingoes did well at this.

Christian: Okay.

Ellen: Yeah. So dingoes seem to have kind of a good mix between being able to take social cues and also being able to critically think on their own.

Christian: Interesting.

Ellen: Yeah. So it's, it's kinda cool because it gives them the best of both worlds intellectually. Right? So here's another thing that they can do: spontaneous tool use.

Christian: Woah!

Ellen: Yeah. So captive dingoes have been observed manipulating objects in their enclosures, such as moving a table to access different heights. Yeah. So like, pushing around like a table or, or some sort of structure in their enclosure to get to a higher area that they couldn't get to before.

Christian: Interesting.

Ellen: Yeah. And they have even been recorded opening gates.

Christian: That's... not great.

Ellen: Like learning how to open gates. It's not ideal. It's not what you want your dingo to start doing, but at least it means it's pretty clever. This is a pretty smart little guy. Another thing that I thought was pretty clever of them is that both parents participate in rearing their pups. Not to, you know, ascribe too many human values to animal behavior, it's just, I have a soft spot for some egalitarian parenting roles. So they do a pretty good job, you know, raising their puppies. So I wanted to kind of highlight the intelligence of the dingo by contrasting it against that of Canis familiaris. In particular, the beagle that is at my feet currently. Her name is Puppy, and I gave the dingo a 9 out of 10 for ingenuity, I give my beagle a 2 out of 10 for ingenuity. She is bad at interpreting social cues. She cannot detour. She frequently gets her leash stuck on poles and cannot figure out that she has to walk backwards to get it unstuck. So if we are taking her for a walk and her leash gets wrapped around a pole, she just cries until we fix it for her.

Christian: I guess I'll just die.

Ellen: Guess I'll die here. Guess this is where I live now. And as far as spontaneous tool use in our dog, there has been one isolated freak incident of sophisticated tool use.

Christian: Yeah...

Ellen: That one time we had a baby gate at the bottom of our stairs and we were leaving her downstairs by herself, unsupervised, and we came home one day and the baby gate, which was mounted to the wall with these tension bolts that you had to twist in order to push them against the walls... The gate had been removed from the wall. And we were like, huh, that's weird. So we just put it back and thought nothing of it, and then the next day the exact same thing happened again. And we were like, how is this gate coming apart from the wall every day now? So we put the gate back on the wall, and then left puppy downstairs and went upstairs and watched, and we saw her go up to the gate and use her paw to twist the bolt that had the gate mounted to the stairs. And I tell you what, that was probably the most insane thing I've ever seen because this dog is dumb as a brick. This is not a bright dog. This is the dumbest dog I've ever met in my whole life. And she had figured out the mechanics holding the baby gate in place and how to dismantle them. So that was just, I think that was like... An outlier, right?

Christian: It was a freak accident. Because she'll do that, right? Where she'll paw at the bottom of something she's trying to get in, and then it just so happens that that motion was exactly what she needed to do to unscrew that bolt.

Ellen: I know, it was just the most bizarre thing that this very dumb dog was able to figure out such a high level task. It's crazy. So yeah, overall, I mean the dingo has got this one in the bag. I think a dingo is way smarter than our dog.

Christian: Yeah, that's what I was going to ask, did they do the same test they did all the, like the domesticated dogs where they did a list- like, a ranking of dog intelligence? I wonder where the dingo would fall in there.

Ellen: I mean it really varies depending on the task that you're trying to judge them on. Right?

Christian: True.

Ellen: They didn't necessarily outperform either dogs or wolves in any of the tasks, but they had consistently higher.... Right? Like whereas one task the wolf would be terrible at but the dog would be good at, the other one the dog's terrible at but the wolf's good at, the dingo's like, consistently pretty good at all of them. They're not necessarily the best at any of them.

Christian: The Jack of all trades.

Ellen: Yeah. So this is a clever, clever dog I think. So finally this brings me to aesthetics for the dingo. I give them a 9 out of 10. This is a good boy. It's a good boy. They're just, they're really pretty. They're cute. They have these long, like slender legs and pointy ears and they have kind of a bushy tail. They have short fur all over their body, but their tail is bushier than you might expect it to be. Yeah. I don't know. It's just cute dog. That's all I got. What more do you need? What more do you want from me? It's a cute dog! Leave me alone!

Christian: Dang...

Ellen: So miscellaneous information for the dingo, their conservation status is... Vulnerable...? This one's kinda tough to nail down because, like I said earlier, there's still some debate over whether they count as their own species. So it's kind of hard to give them an independent conservation status because nobody's really- nobody has come to a complete consensus and complete agreement on whether they count as their own species. So, breeding and hybridization with domestic dogs has actually eroded a lot of the genetic consistency of the dingo. It's estimated that about a third of the wild dingoes in Australia are actually hybrids with dogs. So since dingoes are Australia's largest mammalian predator, and they are opportunistic hunters who will pretty much eat anything, they are seen as pests by a lot of people in Australia. So there have actually been organized efforts to reduce dingo populations, especially in agricultural areas that are trying to protect their livestock because dingoes will hunt anything basically. And they're very, and they're quite good at it, so they're going to get what they want. The Australian Dingo Foundation is a nonprofit that operates a dingo sanctuary and participates in research and conservation of the dingo. So those studies that I mentioned earlier testing their intelligence, those were performed on dingoes kept in the dingo sanctuary by the Australian Dingo Foundation.

Christian: Makes sense.

Ellen: Yeah. So they do a lot of the research in learning more about dingoes, which is really cool. So laws protecting dingoes and dingo hybrids vary across regions in Australia. Some places protect them and consider them an endangered species, some consider them pests and an invasive pest. And so that's, it's just like you're going to get a wide range of policies on dingoes in different areas. So that's why the taxonomy of the dingo matters. So if it is its own species, it can then be classified as endangered. However, if it is just seen as a dog, then it has a lot less footing for legal protection.

Christian: Sure.

Ellen: Cause then it's just like, it's a feral dog, right? There's dogs everywhere, you don't need to worry about it. It's just a dog. So that's kinda why taxonomy matters. In this case. It's like whether you are going to be able to protect the species or not.

Christian: Sure.

Ellen: I know that when I was a kid, I had a book that was really important to me that was a dog breed encyclopedia. I think we just got rid of it, like in this move to our new house. We got rid of the book, but it was really important to me and the dingo was in that book as a dog breed.

Christian: Aw.

Ellen: So I want to wrap up with this one last little tidbit that I really love. This is a story. In August of 2019, a lone puppy fell from the sky into a residential backyard in Wandiligong, Australia. The puppy had marks on its back that suggested it had been picked up and carried off by an eagle. So they think that's how it got to where it was all by itself, with nothing, no family nearby or anything. So the family that lived there took the puppy to a vet where the vets discovered that the puppy was a purebred alpine dingo.

Christian: Wow.

Ellen: The rarest type of dingo, they're actually endangered. So he now lives at the Australian Dingo Foundation's Dingo Discovery Sanctuary. His name is Wandi, after Wandiligong where he was found, and you can follow him on Instagram at wandi_dingo.

Christian: Woah!

Ellen: That's W-A-N-D-I, underscore, D-I-N-G-O. [to the tune of "Bingo Was His Name-O"] D-I-N-G-O, D-I-N-G-O...

Christian: And Dingo was his name-o.

Ellen: Yup!

Christian: Ah. So, should I keep a dingo as a pet?

Ellen: No.

Christian: Okay!

Ellen: No.

Christian: But you just said-

Ellen: No, no, no, no. Don't keep wild animals as pets. Don't do it.

Christian: That's okay. They're probably poor pets anyway.

Ellen: They're bad pets. They- no. Don't keep dingoes as pets.

Christian: I was joking for, for our listeners' sake. Okay.

Ellen: Well no, cause I think that's a good thing to say. I think that's a good thing to include in the show for people that might be listening, and might be hearing me talk about, oh, it's a really cute dog that is also pretty clever. They might be thinking, "oh, where do I get a dingo and keep it in my house?" This is me telling you: don't. You don't. You just don't do that. So that's the dingo.

Christian: Thanks honey. It was very good, and not traumatic at all.

Ellen: Well, thank you to everybody who has spent this time with us this week. We really appreciate everybody that's been listening and we haven't asked this in a while, but if you could please head over to your favorite podcatcher and drop us a good review. I hope we've earned it.

Christian: Or any review, whatever you think we deserve.

Ellen: If you have a bad review, please don't leave that.

Christian: I'll read it.

Ellen: Please keep, please keep that one to yourself. Actually, if you have a bad review and you have negative feedback, you can send it directly to Christian.

Christian: Yeah!

Ellen: Don't send it to me. I'll cry.

Christian: I definitely won't read it on a Mean Tweets type thing.

Ellen: I will cry. I can't take it. I promise. Christian can though.

Christian: Yeah.

Ellen: So yeah, thanks everybody who's been checking us out. That's really cool of you. You can come hang out with us on social media. We're on Facebook, Twitter, and Instagram. Just search the name of the show. You'll find us. Come join our Facebook group. It's pretty great. We love it a lot. If you want to hear us talk about a particular animal species, send those to us either on social media or via email. My email address is ellen@justthezooofus.com. A transcript of this episode will be made available at justthezooofus.com.

Christian: Very good.

Ellen: Yeah, and last mention, thank you to Louie Zong for allowing us to use the song "Adventuring" off of your album Bee Sides.

Christian: Always a pleasure to listen to.

Ellen: Yes, as I hope so is our podcast.

Christian: Oh!

Ellen: I think it is. I think you have a very lovely voice and I like to hear it.

Christian: Nuh-uh...

Ellen: It's a good thing I like to hear it cause I have to listen to it three separate times!

Christian: Yeah... Okay.

Ellen: Anyway, byeee!

Christian: Bye everyone.

29: Delacour's Langur & Komodo Dragon

Ellen: Hi there! This is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast where we take your favorite animals and we review them and rate them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: We are not zoological experts. We do a lot of research and we try our best to make sure we're presenting information from trustworthy and good resources.

Ellen: Before we get into it today, I just want to real quick say that if you are listening to us in Jacksonville, Florida and you want to come see us, we are having a live show at Cultivate on Saturday, November 30th so come hang out with us in the real world.

Christian: Yeah, and not just Jacksonville listeners, the general Northeast Florida folks or you know, if you want to make that trip, do it.

Ellen: If you're listening to this in Canada, Europe...

Christian: I guarantee it'll be warmer.

Ellen: That's absolutely true. It is a little bit chilly today. Today it was 50 degrees this morning.

Christian: Fahrenheit.

Ellen: That's true. Yeah, Fahrenheit. So it was a little chilly, which I know probably to people that might be listening up north in Canada or perhaps the UK, it might sound pretty not cool of us to complain about it being 50 degrees, but we're bundled up in sweaters and the dog is sleeping on a heating pad right now.

Christian: Had to bust out the long sleeve t-shirts.

Ellen: We did! I'm wearing long sleeves today for the first time in a while. So, it's getting a little chilly here, but it's still nicer than it is up north, so if you're feeling a little snowbirdy, you can come down to Jacksonville and hang out with us.

Christian: Do it. So, who's up first?

Ellen: Me, it's my turn.

Christian: What do you got for us?

Ellen: This week I'm talking about Delacour's langur. Before I get any further into this, I want to know what you think a langur is.

Christian: Is it a mammal?

Ellen: Yes.

Christian: Okay. Starting off strong. Is it a monkey?

Ellen: Yes it is. It's a monkey.

Christian: Okay, here we go. Here we go.

Ellen: Where do you think they live?

Christian: What was the first word? Delacour?

Ellen: Delacour's langur.

Christian: Africa.

Ellen: Nope.

Christian: Dang it!

Ellen: Sorry.

Christian: Asia?

Ellen: Yes. Yeah, so the scientific name of this species is Trachypithecus delacouri.

Christian: Okay.

Ellen: This species was submitted by our friend Sarah, who is on Twitter with the Twitter handle @LangurLover. So Sarah loves langurs and requested that we talk about langurs.

Christian: Okay!

Ellen: Yeah. Which I honestly had never even heard of a langur before, so...

Christian: Me neither. I just got lucky on a couple of those guesses.

Ellen: You did. You did really good. Just right off the bat, I'm going to say right at the top, this is one of the rarest species of monkeys in the world. They're one of the most endangered species of primates in the entire world. There are very, very few of them. I'm only saying that to preface the fact that it was a little bit challenging to find very much information on them. So the information that I'm getting for my segment I got from a couple of papers. So the first one was by Lee E. Harding, a profile on the species published in the scientific journal Mammalian Species in 2011, and my other source is a dissertation titled the "The foraging ecology of the Delacour's langur in Van Long Nature Reserve, Vietnam" by Catherine Workman at Duke University's Department of Evolutionary Anthropology.

Christian: Interesting.

Ellen: So two pretty good sources that I was able to find for some good information on this langur. So, to introduce you to my new friend, just some basic details. Their adult size is about 2 feet, or 60 centimeters long. Their tail is about 3 feet or 90 centimeters long. So the tail is longer than the body.

Christian: Yeah, they're like three-fifths tail.

Ellen: They're mostly tail. So the tail is huge. It's this big, bushy tail. The males are a little bit bigger than the females and they are found in Vietnam, but very specifically, their biggest viable population is found in Van Long Nature Reserve, and they live in limestone karst forest. This was a new word for me to learn. Karst.

Christian: Yeah.

Ellen: This is an area with a landscape that's formed by eroded limestone.

Christian: Oh, interesting.

Ellen: Yeah. So the limestone erosion forms structures that could be caves, they could be towers, they can be cliffs. Sometimes there's even like underwater river structures.

Christian: Yeah.

Ellen: But you see this kind of imagery a lot when you see especially videos of the landscape in Southeastern Asia, right? You think of those like big jutting, limestone towers that you'll see towering over forests and stuff.

Christian: Yeah.

Ellen: This is what I'm talking about. Limestone karsts.

Christian: Okay. Interesting.

Ellen: I had heard of these areas, but I didn't know that there was a word specifically for that. So that's where they live. Now, the taxonomic family for this species is called Cercopithicidae. This family is the Old World monkeys.

Christian: Okay.

Ellen: So first, I'm going to talk about the difference between apes and monkeys. Generally speaking, you can tell an ape from a monkey by the tail and whether they have one or not. Generally speaking, if they don't have a tail, they're probably an ape, unless they're a Barbary macaque, which is a monkey, but it doesn't have a tail.

Christian: Okay.

Ellen: But apes are also much larger than monkeys. So when you're thinking of apes, you're thinking of chimpanzees, gorillas, orangutans. They're just much chunkier. They're a little bit more substantial. And then monkeys tend to be a little bit more slender. They're a little bit more made for jumping around in the trees, and they have a tail. Within the monkeys, there are two different groups of monkeys. There's the Old World monkeys, or the catarrhines, and then there's the New World monkeys, or the platyrrhines. And those names have to do with the shapes of their nose. But the common names of Old World and New World refer to their locations. So Old World monkeys are found in Africa and Asia, and then New World monkeys are found in South America. Are you keeping up so far?

Christian: Yeah. What I was thinking, what about the ones in North America? Probably also New World?

Ellen: What ones in North America?

Christian: There are monkeys in North America. Right?

Ellen: They came from South America.

Christian: Oh, they're not...

Ellen: They're not native to here.

Christian: Oh man. Well, I mean until about less than a year ago, I didn't know there were monkeys in North America.

Ellen: Right, right. We were in Fort Lauderdale a few months ago and we saw some monkeys just running around in Fort Lauderdale and they were like, jumping on cars and stuff.

Christian: But you know what? I should retract. It was actually long ago when we saw monkeys in Mexico.

Ellen: Yeah, I mean that's still Central America, you know?

Christian: Yeah.

Ellen: Okay. I guess I should say Central and South America is where you'll find monkeys.

Christian: Okay, cool.

Ellen: So one of the big differences between Old World monkeys and New World monkeys is that New World monkeys typically are the ones with prehensile tails. Old World monkeys have the long tail, but it's more for balance. They can't grip things with it. So I'm going to get into my ratings for this animal. I'm going to start with effectiveness, and if this is your first time joining us, we define effectiveness as physical adaptations that an animal has that make it a little bit better than others at doing what it's trying to do or just let it do a good job. These are physical advantages. It has. I'm going to give the Delacour's langur a 7 out of 10. They have that long bushy tail that I mentioned, but like I said, it is not prehensile. It's made for balance, so they will hold it in different ways that let them navigate narrow passages a little bit easier. So they actually spend most of their time on rocks and cliffs, more so than in trees. They spend most of their time hanging out on the rocks. They walk and run more than twice as often as they climb. So they use that big thick tail to balance and give it an advantage not only in the trees but on the jagged karst surfaces.

Christian: Okay.

Ellen: It's pretty cool. So they've kind of translated that skill of running around in the trees over to running around on cliffs. What's interesting about that is they aren't actually evolved to be adapted to these limestone karsts. They weren't originally meant to be there.

Christian: Okay.

Ellen: So this is implied by two different factors. This information is coming from that dissertation that I mentioned. So the first factor is diet. So they're folivores. They eat mostly leaves, but some other little plants, like fruits and seeds, stuff like that. But like most of what they eat is leaves. The plants that they eat the leaves from are not endemic to limestone karst habitats. So they probably didn't evolve in those habitats because if they did, their diet would probably be more specialized to those plants.

Christian: Okay.

Ellen: That implies that their habitation of these areas is a little bit more recent. The second factor is something that I had never heard of, but I had a really good time learning about it. It's called their intermembral index. This is a ratio that describes the proportional lengths of an animal's limbs to each other, specifically their forelimbs to their hind limbs. This is converted into a percentage. So to give you an example, a human, think about the way that a human is shaped. Our legs are much longer than our arms, because we get around with our legs, we use our arms for other stuff, but our primary locomotion is our legs. So having much larger legs than arms, we have an entire memberal index of around 70%. however, a chimpanzee who spends more time swinging and hanging in trees than a human has much bigger arms, and their arms are actually a little bit longer than their legs.

Christian: Yeah.

Ellen: So that gives them an intermembral index of closer to 110%.

Christian: Yeah, yeah.

Ellen: So this makes sense so far.

Christian: Yeah. So, anything over 100%implies arms longer than legs.

Christian: Yes. For Delacour's langur, their intermembral index is around 76%, which is what you would expect of a primate who does a lot of leaping and jumping, like across tree limbs. But based on their jagged rocky habitats, you would probably expect them to have longer forearms to give them more stability as they're walking across the cliffs and make them better at like, climbing and getting around on the rocks. You wouldn't expect their body to be shaped like that for where they live, suggesting that where they live is not where they were supposed to live. At least they haven't lived there for long enough to physically adapt to it. This all suggests that they're living in these karsts out of necessity rather than preference or adaptation. This is likely resulting in them being forced into these areas by deforestation and agricultural conversion. So the forests that they should be living in are being repurposed, and it's not an option for them anymore. So they're being forced into these areas.

Christian: Right, okay. Because it's not like the limestone just popped up one day, right?

Ellen: The limestone's been there forever, but they haven't lived there forever. They're kind of just trying to do their best with what they've got.

Christian: Okay.

Ellen: So that's why I gave them a 7 out of 10, is that they're not perfectly adapted to where they live, but they're flexible enough that they can still live in a place that they're not necessarily made for.

Christian: Yeah.

Ellen: That ties into the next category for their ratings, ingenuity. We define ingenuity as behavioral adaptations that give an animal kind of an advantage over others or that give it a better time of solving the problems it needs to solve everyday. Give them an 8out of 10.

Christian: Alright.

Ellen: Monkeys tend to be pretty clever. So these are Old World monkeys. Old World monkeys have been shown to have comparable intelligence to apes in terms of spatial understanding, tool use and social intelligence. So this suggests that they're probably similarly intellectually competent. Even though I couldn't find very much evidence to suggest tool use for this specific species, although they don't eat anything that would necessarily require the use of tools. It's just leaves, right? You don't need anything to get a leaf. It would make more sense that they ate things like insects or like fruit that was hard to get at, that would require them to use something to get to.

Christian: Yeah. Cause like for me the poster child of animals using tools would be like an ape using a twig to get termites out of a mound.

Ellen: Right. And they don't do that.

Christian: Yeah.

Ellen: So it's not something that they need to do. I'm sure if they needed to, they could. By nature of being a monkey, which tend to be pretty smart. So I did kind of give them a bump because even though they're not physically adapted to them, they use the rocks and ledges of the karst environment to their advantage. So they're not only chilling out on the rocks, they're taking shelter from the heat and the sun in the caves. So there's lots of caves in these areas and they'll chill out inside of there, which is not a thing that monkeys typically do. They don't usually go into caves, but they'll go in there to take shelter from the weather. They will also sun on the rocks to warm up during the winter. So when it starts to get chilly, they will actually lay out on the rocks because the rocks will heat up a lot quicker than the surrounding area and they'll lay out to sun their bodies.

Christian: Yeah. I was just realizing, you know, Vietnam has some very intense rainy seasons.

Ellen: Yeah. And also some intense heat too. It gets really hot. Yeah. They kind of use the rocks to their advantage even though they're not necessarily physically evolved to live there. So another thing that they do is that when they're scaling the rocks, they follow behind each other in single file. So this makes it a lot safer for them to travel in groups, because they do group up rather than each monkey individually finding its own way up the cliff. They travel as a group in single file.

Christian: Yeah. So they'll be like, "Oh, the monkey in front of me found a safe handhold. I'll use that one."

Ellen: Yeah. So it just makes it a little bit easier for them to travel together. Something that I really enjoyed that I thought was really kind of adorable, the dissertation that I mentioned earlier by Workman noted young langurs jumping off of the rocks into trees below and then climbing back up and doing it again.

Christian: Parkour!

Ellen: It's like, it was compared in the paper to like how a human would jump off of a diving board into the water. Like they would jump off of the rock, land in the trees, climb up the rock and jump off again. So they weren't like chasing anything or like, they weren't doing anything, they were just having fun. I think that suggests a level of intelligence, right? That they're doing things for enjoyment.

Christian: Yeah, yeah. I mean it seems a little bit a little dangerous, but hey.

Ellen: I mean, it's thrill seeking, baby. They're adrenaline junkies. They don't care. To talk a little bit about what their social structure looks like, they usually live in groups of harems, which is one male and multiple females, but there are some variations on the structure. Sometimes there'll be groups of multiple males or groups with no males. You know, it can, it can be a little bit different. The males serve as lookouts for the group, sitting high up on the rocks and keeping an eye out for predators or other langurs. They don't typically mesh with other groups. When two groups of langurs cross paths, the males will react defensively. They will first yell at each other. So you got to talk a little trash before you really get into it. So they'll yell at each other first for a little while. Usually one will back down, but if not, they will escalate to chasing each other or even fighting if they have to. So members of those groups bond really closely with each other by playing or by grooming each other. This is mostly females that do this, but sometimes the males will groom each other, like males will groom other males. It's mostly females that do the grooming. So the last kind of note that I had for their behavioral advantages, which I, I read this line in this study and it resonated so deeply with my soul: "resting dominates the daily activity budget."

Christian: Aw, yeah. Put that on a pillow.

Ellen: I was like, yeah, man, same. Resting dominates my daily activity budget. But so there's actually a reason for this. They are lazy on purpose. This strategy, I suppose, of spending most of their time resting allows them to conserve energy and spend more time digesting that like super high fiber diet of like mostly leaves. Right? We talked about this with a sloths.

Christian: Yeah, I was about to say, I think we've, we've seen this a couple of times now with animals that primarily eat leaves.

Ellen: Yeah. If you eat a lot of leaves, you actually aren't gonna end up with a lot of energy to be doing other stuff.

Christian: Like pandas.

Ellen: Yeah. Well, they're not supposed to be like that. I consider this tactical laziness.

Christian: Yeah. I mean, conservation of energy.

Ellen: Yeah. So I enjoyed that. That's my 8 out of 10 for their ingenuity. And finally, this brings us to aesthetics. For aesthetics for this animal I give them a 10 out of 10. This is a gorgeous monkey. Um, I know-, I don't think you've seen it yet.

Christian: No.

Ellen: You haven't seen it yet. So hopefully anybody listening to this would have already had a chance to Google them real quick.

Christian: I do have a mental image. I'm kinda curious to see how it stacks up.

Ellen: Can I hear your mental image first? What do you think they look like?

Christian: I'm imagining it's like, a golden fur...

Ellen: Nope.

Christian: No? Dang it...

Ellen: What do you think their face looks like?

Christian: I'm imagining a, almost a spider monkey type face.

Ellen: Okay. They have the flat face, like those other types of monkeys. It's not a long face like a, like a lemur or something.

Christian: Sure.

Ellen: But so the body is mostly black. Now here's the kicker. Here is the selling point of Delacour's langur: they're wearing white shorts.

Christian: Whaaat?

Ellen: They have a black body and white shorts. It's like this patch of white fur that starts at their waist and it goes down to like, just above their knees. It's the best thing I've ever seen in my life. It also makes them look kind of like a panda a little bit. It's similar to a panda's markings.

Christian: Interesting.

Ellen: Yeah. I think it looks panda-like. They also, on top of their head, they have this crest of hair that looks a bit like a mohawk.

Christian: Oh boy.

Ellen: Yeah. So it gives their head this teardrop shape. Their head is shaped kind of like a teardrop, how it tapers at the top because of this Mohawk.

Christian: Yeah.

Ellen: So what this reminds me of is the chaos from the Sonic the Hedgehog video games. There are these gardens where you take care of these little adorable creatures called chaos, and they have that teardrop-shaped head and they're really cute.

Christian: I'll have to take your word for it.

Ellen: It's adorable. Trust me. Now, the babies are bright orange.And they have these huge giant ears. Big round ears, and they stick straight out on either side of their head, and the head is onion-shaped, so they have this big orange onion head and giant ears and it's perfect. And then they turn gray and then they turn black. It's the cutest thing.

Christian: I bet it's so the parents can keep track of them easier.

Ellen: It's a little safety vest. It's a high visibility- Oh my gosh, we should just start doing that with like, like human babies in crowded environments and stuff.

Christian: I think you could just connect the tile to like, the back of their shirt.

Ellen: Our little Bluetooth tile?

Christian: Yeah.

Ellen: Find my child. So yeah, that's my 10 out of 10 aesthetics for this. This is a really beautiful monkey. It's absolutely gorgeous.

Christian: I'll have to look it up afterwards.

Ellen: Okay. Please do. So miscellaneous information: as I mentioned earlier, they are super duper not doing so good numbers wise. Their conservation status is critically endangered.

Christian: Wow.

Ellen: Yeah. This is one of the world's most endangered primates. There is an estimated around 250 left in the world. So there are two primary threats facing this monkey, the first of which is actually hunting by humans.

Christian: Really?

Ellen: So humans hunt them for their bones and tissue, which are ingredients used in traditional folk medicines.

Christian: Okay.

Ellen: Yeah, you hate to see it. Another major threat is obviously the heavy loss and fragmentation of their habitat. So there's a lot of deforestation that has forced them into those limestone cliffs, and also there's quarrying for limestone. Nowhere is safe, right? Like the forest and the limestone are both kind of under attack. So in more recent years there's been actually a pretty decent little increase in their population, like over the last decade or so. There have been massive conservation efforts including the establishment of the nature reserve that protects the area where they live in, and the nature reserve is actually equipped with dedicated staff and guards to deter poaching. And they've started to reintroduce captive-bred langurs into the nature reserve.

Christian: Okay.

Ellen: So they've been breeding them in captivity, there's only like 19 of them in captivity.

Christian: Yeah.

Ellen: So they've started breeding them in captivity and then reintroducing them into the wild, and they're starting to actually take off. So in much more recent studies of their populations, their numbers have increased a lot.

Christian: Good!

Ellen: So it seems like they're on an upswing, but still, I mean it is precarious. So there are a lot of organizations that are putting a lot of work into making sure that they stay on an upward trend. The ones that I could find were the Rainforest Trust and this organization called Flora and Fauna International. So they're both kind of putting a lot of footwork into helping out this monkey. I wanted to kind of spotlight it because I had never heard of it, and it ended up being really, really interesting and cool and beautiful, and so I wanted more people to know about Delacour's langur.

Christian: It's a good one.

Ellen: Yeah, that's my segment. That's my animal for this week.

Christian: Well, thank you, honey.

Ellen: You're welcome. Before we do Christian's animal, just a real quick shout out to our Patreon supporters this week, I would like to thank Briana Feinberg, Krystina Sanders, the Jungle Gym Queen, and Jacob Jones.

Ellen: Okay, baby. What you got?

Christian: All right, so this week I bring you in the listeners the Komodo dragon.

Ellen: Fantastic. Absolutely incredible.

Christian: Yes. This species was submitted by Kyle Rauch.

Ellen: Thank you.

Christian: And also the Varmints! Podcast.

Ellen: We love them. They're our very good friends.

Christian: Very good. The scientific name for Komodo dragon is Varanus komod- komodoensis.

Ellen: Komodoensis?

Christian: Yes.

Ellen: Oh, interesting. You said commode for a second, which- I don't know if this is elsewhere in the world, but in the American South, a commode means toilet.

Christian: It does. My information is primarily coming from the Smithsonian National Zoo website, found out nationalzoo.si.edu. Let's talk about Komodo dragons. I think this is a very visible animal. It's been in the media lots of times for quite some time.

Ellen: It's a popular boy.

Christian: It is. Let's talk about how big they get. So they weigh around 70 kilograms, or 154 pounds.

Ellen: 154 pounds!

Christian: Yep. The males tend to be longer and heavier than females. The largest verified specimen was 10.3 feet...

Ellen: No it was not.

Christian: Or 3.13 meters long.

Ellen: Stop it.

Christian: And weighed 366 pounds, or 166 kilograms.

Ellen: I'm so stressed out. That's so much. It's so much lizard.

Christian: It's big. So their weight tends to vary greatly, and I'll touch on that on why that is later. Where they are found are a few Indonesian islands called Rintja, Padar and Flores, and of course Komodo.

Ellen: Oh, it's the Island.

Christian: Yes.

Ellen: Oh wow.

Christian: They're named after that Island.

Ellen: Oh, they're named AFTER the Island.

Christian: I assume.

Ellen: That would make sense. Yeah.

Christian: However, they haven't been seen on the island of Padar since the 1970s. These islands are mostly tropical savannah forests. They belonged to the taxonomic family Varanidae, and that consists of most of the monitor lizards.

Ellen: So it's a type of monitor lizard?

Christian: Yeah, that's a good way to classify it. I'm going to jump right into effectiveness.

Ellen: Let's hear it.

Christian: So this is where the Komodo dragon really shines. I'm giving it a 10 out of 10 for effectiveness. So first, as you might have guessed, it is the largest living lizard in the world.

Ellen: So it is a lizard.

Christian: It is a lizard.

Ellen: Okay.

Christian: Not like crocodiles or alligators.

Ellen: That always trips me up, cause gators I always think look like lizards, but they're not.

Christian: Yeah. They can eat up to 80% of its own body weight. That would be equivalent of me eating about 220 pounds of food.

Ellen: So one of those peanut butter milkshakes that we had a couple of days ago.

Christian: So I mentioned a minute ago that their weights can be pretty drastically different. So this is because it kind of depends on when it was the last time they ate.

Ellen: Oh my gosh. It has that much of an effect?

Christian: Yes.

Ellen: How often do they need to eat?

Christian: I imagine not very often, based on how other reptiles do it.

Ellen: Yeah. Because I know if you have, like for example like a pet snake that is eating like, rats and stuff, you don't need to feed them very often.

Christian: Right. But yeah, so the weight largely depends on when was the last time they ate. Cause if they had just eaten, they're going to be much, much heavier than they normally are.

Ellen: Sure. That makes sense.

Christian: Yeah. They're at the top of their food chain in their environment.

Ellen: Naturally.

Christian: And they're also cannibalistic.

Ellen: *gasp* What?

Christian: Yes.

Ellen: Oh no.

Christian: This is going to be a theme, but let's talk about their food. So the young feed on small lizards, insects, snakes and birds, whereas once they get to 5+ years old, they start eating larger, prey such as rodents, monkeys, goats, wild boar and deer. Sometimes even water buffalo.

Ellen: Oh no. Those things are big.

Christian: They get big. My next point here for effectiveness, they have small bursts of speed. They can reach 10 to 13 miles per hour, or 16 to 20 kilometers per hour.

Ellen: That's okay.

Christian: Small burst of speed. That's not what they depend on though, usually.

Ellen: Right.

Christian: I'll talk more about their hunting methods in the ingenuity section. They have a very good sense of smell. They use their tongue to smell like many reptiles do, and snakes.

Ellen: Yeah, I think of snakes when I think of that like, tongue flicker thing.

Christian: Yep. So they have a big long forked tongue that they'll stick out and pull back in, and will rub against, I think it's called the Jacobson's organ on the top of their mouth.

Ellen: Okay.

Christian: So that's how they get the particles out of the air. So this is their primary way of finding food. They use this smell method and their undulatory walking, where as they're walking, their head is going from side to side so that they can tell, "okay, my head was pointing to the left, I could smell something, but if I pointed it to the right, I can smell it stronger. So it must be that way."

Ellen: Oh, that's why they kind of swagger like that.

Christian: It's part of it. Yeah.

Ellen: Okay. It's so funny to watch them walk, cause it's kind of like my mom's dog. My mom has a big dog with a big tail, and when the dog wags the tail, the tail wags the whole body. Right? So the whole body ends up like, shifting from side to side. And when the Komodo dragon walks, it kind of has that sachet to it a little bit.

Christian: Yeah. So that's it trying to get a direction.

Ellen: What catwalk anthem would you play to a clip of a Komodo dragon walking?

Christian: "You can tell by the way I use my walk..."

Ellen: I was also thinking that too! I was also thinking "Stayin Alive" by the Bee Gees.

Christian: Thanks. So yeah, that's how they find their prey. They can smell carrion, or rotting flesh...

Ellen: Sure, dead stuff.

Christian: ...From up to two and a half miles away, or four kilometers away.

Ellen: You're never safe.

Christian: Next is their sight. They can see objects as far away as 985 feet, or 300 meters. Or, to put that in perspective, 3 football fields,

Ellen: That is way better eyesight than I expected.

Christian: It's different though. So they're better at seeing movement rather than stationary objects, and their retinas have only cones, rather than how our eyes have cones and rods. So that means it's thought that they can distinguish color, but they have poor vision in dim light. Next up is their hearing. They have a smaller hearing range than humans, so they cannot hear sounds like low pitched voices or high-pitched screams. Why they specified it like that, I don't know.

Ellen: They needed you to know the Komodo dragon can't hear you scream.

Christian: So, to be undetected in terms of sound, I guess you just [in a very deep voice] talk way down here.

Ellen: So you've got that covered.

Christian: Yep.

Ellen: So you can- I don't think a Komodo dragon could hear you.

Christian: Yup. I guess you'll have to just scream constantly.

Ellen: Just mask myself with a constant barrage of screaming.

Christian: Yeah. And next is one of my favorite things about them, is their venom and bacteria in their saliva.

Ellen: Here's the moneymaker.

Christian: Yep. So for a long time it was thought that it was just bacteria, but I think it was somewhat recently discovered there's also venom in play.

Ellen: Sure, why not? Just go for both. Right?

Christian: So meat from previous meals get stuck between their teeth, and that encourages bacterial growth. They've been found to have over 50 different strains of bacteria, 7 of which are highly septic.

Ellen: Interesting. So poor dental hygiene is really their strength here.

Christian: "Why are they so deadly?" "It's because they ain't got no toothbrush." And they have a venom gland and their lower jaw.

Ellen: Oh, that too, also.

Christian: Yes. So those two things combined makes it so that when they bite something, that wound is going to be so that the blood can't clot. So that's the effect, and so that leads to blood loss and eventually shock and death.

Ellen: Oh my gosh.

Christian: Yes. The Komodo dragons are immune to both the venom and the bacteria. It's thought that perhaps it's because of antibodies in the Komodo dragons, but they are still researching this.

Ellen: So they cannot envenomate each other.

Christian: Correct.

Ellen: Oh, I guess that's helpful for them... Trying to eat each other.

Christian: Yes. Well, that and also their mating rituals, which I'll talk about later. But they have serrated teeth for tearing through flesh and then they just swallow the whole chunk of meat.

Ellen: So when you say serrated teeth, you mean like kind of jagged like a knife?

Christian: It's hard to describe. You'll want to take a look at it. Like you can see pictures of their teeth. It's very different from what you see in other animals. So it's designed to tear flesh into chunks, which it'll then just swallow whole.

Ellen: Sure. Interesting.

Christian: Yeah. Speaking of, they are efficient eaters, so they'll only leave about 12% of their prey behind when they're done. So they eat bones hooves, hide and intestines.

Ellen: They're not picky, huh?

Christian: Here's the thing though, before they eat those intestines, they will tear them out and swing them around to dislodge their contents before eating those intestines.

Ellen: Now that's pretty clever. They're like, you know what? Okay, we'll eat the bones, we'll eat the innards, we'll eat all that stuff. But I ain't eatin' poop.

Christian: Yeah.

Ellen: They have standards. Come on Christian.

Christian: So they have their disposition to avoid feces. This is important for later.

Ellen: Oh okay. We'll keep that one locked away.

Christian: Yes. I'm going to move on to ingenuity.

Ellen: I cannot wait.

Christian: I'm giving them a 7 out of 10 for ingenuity.

Ellen: That's decent.

Christian: One: Vomit for speed.

Ellen: What? Nuh-uh.

Christian: Where's what I mean by this...

Ellen: Wait, hold on. Did you get, did you get your Just the Zoo of Us notes and your Sea of Thieves strat notes confused?

Christian: Nope! So earlier we talked about they can eat so much that they increase their body weight by about 80%. So this of course slows them down. So if they find themselves in a situation where they are threatened and they need to run, they will vomit up their meal to lessen their weight so they can move faster.

Ellen: She can't take much more captain! We've got unload! *blech*.

Christian: Go, go, go! That might double as leaving food behind for whatever threatened you.

Ellen: It's it's also bait. It's also a quokka strategy. Okay, so here's my idea for a video game where you play as a Komodo dragon.

Christian: Okay.

Christian: So you have your tank mode, where you've just eaten a bunch of food and that's when you get a defense and an HP buff. And then, when you need to switch to DPS, you puke up all your food...

Christian: As a projectile. You get one projectile for this.

Ellen: Yes, it's an AOE, it's a projectile that does splash damage. And then you're, and then you switch to DPS and you take a cut to your defense and your HP, but you get a speed and an offense boost.

Christian: Yeah.

Ellen: So that's my, that's my idea for a Komodo dragon character. TM. Please don't steal.

Christian: So next up on ingenuity is their hunting methods. So earlier I mentioned they have the capability for bursts of speed, but their hunting method is largely based on stealth and power.

Ellen: Stealth?

Christian: Yes.

Ellen: That's unexpected for such a large lizard.

Christian: So they'll basically hang out on game trails, waiting for something to get near them and that's when they'll use their burst of speed.

Ellen: Oh, okay.

Christian: So they actually have a low success rate when it comes to killing its prey outright. So like meaning attacking the prey and killing them then and there. Very low success rate. Where they shine, though, is the long con. So if it gets at least one bite in, that bacteria and venom we were talking about, it will likely kill that prey within four days.

Ellen: Four days?!

Christian: Yes.

Ellen: Who has that kind of time?

Christian: The Komodo dragon.

Ellen: He gets one bite and he's like, "I can wait. Where you going? "

Christian: Well, it's going to run away and that's fine. It doesn't need to keep up.

Ellen: He's like, I'll get there eventually.

Christian: Because guess what? That thing is going to die eventually, and it will smell it and find it.

Ellen: That is very smart. I like the idea of like, getting one hit in and then being like, you know what, "I'm going to conserve energy. I'm just going to mosey on along."

Christian: Yeah. And plus these are islands, so it's, you know.

Ellen: Where's it gonna go?

Christian: So yeah, the animal gets bitten, runs away, eventually dies. The Komodo dragon will find it and start eating it, but also nearby Komodo dragons, will also find it and eat it.

Ellen: Oh, that's true.

Christian: So you'll usually a big group of Komodo dragons eating one big thing.

Ellen: Oh, okay. And are they like chill with each other?

Christian: Kinda... Kinda. It kinda depends. Here's our next very good thing about ingenuity, and I'm classifying it as "avoiding cannibalism."

Ellen: Avoiding cannibalism.

Christian: So this mostly has to do with the young Komodo dragons. The younger Komodo dragons usually are the ones that fall prey to cannibalism from other larger Komodo dragons.

Ellen: Because why not.

Christian: Remember how I said the feces thing was important?

Ellen: Uh huh...

Christian: So the young ones, to avoid being eaten....

Ellen: Uh. I don't...

Christian: Will roll around in fecal matter...

Ellen: This is horrible.

Christian: So that large dragons won't want to eat them.

Ellen: Well, yeah. Huh.

Christian: Yeah.

Ellen: Well, I don't know how this happened.

Christian: I think it's pretty smart, personally.

Ellen: I don't know how we got here.

Christian: Don't eat me, bro!

Ellen: "I'm covered in poop!" Well, I hate that a lot.

Christian: They do one more thing.

Ellen: Oh no.

Christian: So during these kind of feeding frenzies we talked about, the young ones will undergo what the Smithsonian website referred to as "rituals of appeasement," where they'll pace around a feeding circle in a "stately ritualized walk with their tail stuck straight out and throwing their body from side to side." So what I'm imagining here is like a water buffalo, dead, with a bunch of big dragons eating it, and then a bunch of smaller ones just walking around in a circle like, "Yeah! We did it! Yeah yeah yeah!"

Ellen: They're having a little Komodo dragon parade!

Christian: Could you imagine walking up on this?

Ellen: And being like, this is some sort of strange coven.

Christian: I want no part of this.

Ellen: They're summoning something.

Christian: This was the plot of Skyrim, I'm pretty sure.

Ellen: They're resurrecting one of their dead dragon comrades.

Christian: So yeah. Interesting techniques to avoid being cannibalized.

Ellen: That was a lot of information I didn't think I was gonna get.

Christian: Me neither.

Ellen: I wasn't emotionally braced for any of that.

Christian: So, that wraps up ingenuity, 7 out of 10. Moving on to aesthetics, also 7 out of 10. I think they have puppy dog faces.

Ellen: They do! They're so cute!

Christian: Granted they're big puppy dog faces, and danger puppy dog faces, but puppy dog faces nonetheless.

Ellen: They have that rounded nose and kind of a broad snout, right?

Christian: Yeah. They, they remind me of pythons in a way, with the shape of their nose and mouth a little bit. Just a little bit.

Ellen: Yeah. And also when you get that tongue flicking thing in there too, it kind of really leans into the Python face look.

Christian: And then they have these very pronounced brow ridges above their eyes.

Ellen: Yeah.

Christian: It reminds me of Godzilla a little bit. Some of the older designs of Godzilla.

Ellen: Probably that was inspired a little bit by the Komodo dragon.

Christian: Could have been. Um, they're very long. They're long boys, although they're not very exciting in terms of color.

Ellen: That's true. They're kind of...

Christian: A little bland.

Ellen: Which is probably good for camouflage and good for not being seen. Yeah. But is it fashion? No.

Christian: And with everything else we learned about them, I'm pretty sure they don't smell very good.

Ellen: There are so a few things that they could smell like and none of them are good.

Christian: It's either rotting meat or...

Ellen: Or poop.

Christian: Yeah.

Ellen: Limited scent options.

Christian: So that wraps up aesthetics for me. On some little fun facts. Their conservation status is vulnerable. However, they were last assessed in 1996.

Ellen: Oh, it's been a minute.

Christian: It's been over 20 years since they were last assessed, and there's no population trend data on them. They are difficult to determine sex between them cause there's no big morphological differences between males and females, other than a slight difference in size. The males compete for females by wrestling.

Ellen: Wrestling each other?

Christian: Yes. The males wrestle other males. You probably have seen this on nature documentaries where they'll kind of clash up on their hind legs and they'll smash their upper bodies together.

Ellen: Chest bump!

Christian: Trying to push one or the other over onto the ground.

Ellen: Okay, sure.

Christian: Yeah. So a lot of times blood will be drawn during these kinds of wrestling matches.

Ellen: I guess it's a good thing they're immune to that venom, huh?

Christian: Yup, yup. And they also have sharp claws, so there's that. So yeah, that's how they fight for females. Their life span in the wild is thought to be about 30 years.

Ellen: Wow. That's old boy.

Christian: Yep.

Ellen: I guess with how big they are, that makes sense. Usually something that is bigger lives a longer time.

Christian: Yeah. And I don't know if this is just because of our experiences, but I feel like I've seen them in zoos a lot. So there's the Jacksonville Zoo has one or two, I believe the Atlanta Zoo had one and the Smithsonian has one in DC. That's why they had an article about them.

Ellen: I do also feel like they're very popular zoo animals. I don't have data on that, but I do feel like it's a very standard thing to see in a zoo.

Christian: Yeah. I'm not sure if it's just anecdotal because we happen to go to the zoos that have them.

Ellen: Yeah. Maybe they're just easy to take care of. Right?

Christian: Maybe.

Ellen: It's just kind of, it's just a lizard but big. You just feed it some... burgers and stuff. But no poop. They will turn that down.

Christian: No!

Ellen: I don't want it! Yeah, so at the Jacksonville Zoo, they do have at least one big Komodo dragon. I think there's more than one.

Christian: Yeah, I think they have one adult and one or two juveniles.

Ellen: I'm sure the juveniles have grown up by now, cause it's been awhile since we've seen them.

Christian: It takes like five years, though.

Ellen: Oh that's- I dunno. But we have, there's at least one. So it's a really, it's beautiful, beautiful Komodo dragon. What?

Christian: I just had a realization why they had two separate habitats for them.

Ellen: To not eat each other?

Christian: Dang.

Ellen: Yeah. So at the Jacksonville Zoo, there's a big exhibit for the Komodo dragon and then there's a smaller one for the babies. Um, yeah, that makes sense. So they didn't get rekt. Yeah. But like you said, kind of meh. Like, cute, but not super interesting to look at.

Christian: No like, dazzling colors or anything.

Ellen: Yeah. So the really funny thing about the Komodo dragon exhibit at our zoo is that right next to the Komodo dragon exhibit, there is a... What is the material that the statue is made out of? Bronze?

Christian: Yeah, something like that.

Ellen: There's like a bronze statue of a Komodo dragon and it's low to the ground where it's meant to be like a photo op, right? Like it's something you can take a photo with and it's sloped in such a way that it is like perfect for a child to like sit on top of or like, sort of recline across because of the slope. It's like a Komodo dragon with the head sticking up and then the body sloped downwards. However, it's made of bronze, and we are in Florida where it gets HOT.

Christian: Yeah. Because it's in direct sunlight.

Ellen: It's right in the sun, too. And so they have a sign, like right next to the statue that says like, "HOT!" Do not, please do not burn yourself on this Komodo dragon. I'm sure it's happened before where people have just kind of glomped right onto it.

Christian: Well you know, there's usually reasons for signs. You know, they say rules are often written in blood.

Ellen: Yeah. So it always, it always makes me chuckle a little bit to see like it's this very beautiful regal Komodo dragon statue, and then right next to it is like, "Don't do it!"

Christian: Too hot to handle.

Ellen: Yeah. I have some really cute pictures of Isaac hanging out with the Komodo dragon statue. Yeah, it's really sweet. So I love our, I love our Komodo dragon at the zoo.

Christian: That's the Komodo dragon.

Christian: Excellent. Nicely done. Thank you baby.

Christian: Anytime.

Christian: Yep. Until next time.

Ellen: Stay warm out there.

Christian: Bye!

Ellen: Bye!

28: Great Potoo & African Giant Pouched Rat

Ellen: Hey there, this is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast where we take your favorite species of animals, we review them and we rate them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: We are many things, but zoological experts aren't among them.

Ellen: What kind of things are we?

Christian: Human.

Ellen: And only that.

Christian: Definitely not multiple beings.

Ellen: We are one being and not several.

Christian: We do a lot of research and try our best to make sure we're presenting you with information that is both trustworthy and good.

Ellen: Only the best. We don't settle for less. Is that our new slogan?

Christian: Let's workshop it.

Ellen: Okay.

Christian: Any announcements today before we get into it?

Ellen: Yes. I'm just going to repeat our announcement from last week that we have a live show coming up, and that if you are in Jacksonville, Florida, please come check us out. We're going to be at Cultivate, which is in the Riverside area on Saturday, November 30th so come check us out. We've got tickets available online, so come join us. It's going to be really great.

Christian: Looking forward to it.

Ellen: Yeah. I believe, Christian, it is your turn to go first this week.

Christian: Excellent. Because this week I have a good birb.

Ellen: A birb friend!

Christian: Yes. Specifically the great potoo.

Ellen: Potoo!

Christian: Scientific name: Nyctibius grandis.

Ellen: Nailed it.

Christian: So this is a specific species of potoo. You'll hear a lot about potoos on the internet right now. It actually refers to an entire family of birds.

Ellen: So there's many potoos.

Christian: There are. But this one specifically, the great potoo. The potoo was submitted to us by Kyle Rauch.

Ellen: Thanks Kyle!

Christian: And I'll be pulling my information from two different places: the Cornell Lab of Ornithology Neotropical birds, found at neotropical.birds.cornell.edu, and also Animal Diversity Web, found at animaldiversity.org.

Ellen: Excellent.

Christian: Two sources I believe I've used many times before.

Ellen: We have some go-tos.

Christian: Yes. So getting right into it, this bird weighs around 360 to 650 grams, which in imperial is 13 to 23 ounces.

Ellen: Oh, he's so light.

Christian: So here's the thing. Their length is 480 to 600 millimeters, or 19 to 24 inches.

Ellen: Oh.

Christian: So they're light, yes, but all birds are kind of like that. But in terms of the birds, this is the biggest potoo, actually, hence the name great potoo.

Ellen: It's an absolute unit.

Christian: And its wingspan is even bigger, as is usual with flighted birds, at 700 to 804 millimeters or 28 to 32 inches.

Ellen: Okay, so that's a good few feet of wingspan.

Christian: Yeah. And just a quick note here, whenever I'm doing these conversions, I'm rounding up, or just rounding to the nearest whole number for simplicity.

Ellen: Yeah, please don't do like, sig figs for your conversions. That's not good audio.

Christian: Yeah. Now, let's talk about where these guys can be found. They're found in Central and South America, from southeastern Mexico, south to northern Columbia, and east of the Andes south to eastern Bolivia and central Brazil. There's also kind of a separated pocket of them found in southeastern Brazil. And they live primarily in rainforests and forests.

Ellen: As birds tend to do.

Christian: Yes. So these birds spend a lot of their time in trees. As I mentioned earlier, their family refers to all potoos and it's called Nyctibiidae, and they're related to nightjars and frogmouths.

Ellen: Oh okay! I know about frogmouths.

Christian: Yes. And you can kind of see that with the way their mouths look.

Ellen: I actually often get them kind of confused for each other.

Christian: Yeah. I don't know if I'd be able to tell the difference either.

Ellen: We actually saw a tawny frogmouth at Zoo Atlanta.

Christian: Yeah. So, like the frogmouth, the great potoo has a short to beak but it's also wide.

Ellen: It's hilarious. Y'all, it looks so funny. It's so ridiculous. It's so short and pointy. It's very, very pointy but it's very short, and it's very, very wide.

Christian: It's got these big mouths.

Ellen: It's really funny looking.

Christian: And the great potoo is nocturnal, so it's doing most of its hunting at night and during the day it stands pretty still. And I'll talk about that here shortly, cause that's kind of its signature thing.

Ellen: It reminds me of an owl. Is it related to an owl?

Christian: Potoos are in a different order than owls, but I do see a lot of resemblances there. Again, in their feet and in the round shape of their heads. That's about where it stops.

Ellen: Some convergent evolution perhaps?

Christian: Perhaps... Another little fun fact here: There is no dimorphism between the sexes, so it's actually very, very difficult to identify which is a male and female in the field.

Ellen: Oh! Interesting.

Christian: Yes, and they usually spend their times apart too.

Ellen: Oh really? Are they like solitary?

Christian: Mostly. Yeah.

Ellen: Oh. Just po-one.

Christian: I'll talk about this a little later when we talk about reproduction, but first: effectiveness, our first category. How good do they do the things they do? Physical attributes, that sort. I'm giving the great potoo an 8 out of 10, and it's pretty much all based on their camouflage. So the great potoo has feathers that are colored and patterned in a way such that they blend in perfectly with tree bark in their regions. If they stay completely still against the tree during the daytime, you're likely not to ever see them.

Ellen: It's like lots of browns and grays and tans.

Christian: And they're like, spotted in the same way that the bark is.

Ellen: Yeah, yeah yeah. I think it's pretty.

Christian: Yeah. I'm also going to talk about this in the ingenuity, but I just want to note the physical attribute of their camouflage, which is the coloration, because the rest of it comes from behavioral type things.

Ellen: Ooh, some more motion camouflage like we talked about in the last episode.

Christian: All right, I'm moving on to ingenuity. This is where they do smart things, or things that take some planning, some forethought, tool use, that sort of thing. Ingenuity, 7 out of 10. So I mentioned their camouflage, so of course during the daytime they'll stay relatively still, but they'll position themselves at the end of like a broken branch or even the main trunk of a tree that's been broken at the end. They'll position themselves there and completely minimize movement. Again, they're nocturnal, so during the day they're not doing a whole lot, but while they are up and about in the day, they'll stay in that spot at the end of the tree, very minimal head movement, and when it senses something nearby, something that's moving, making sounds, something that could be a predator, they stretch out their neck pointed upwards to kind of mimic the end of the branch.

Ellen: So they're pointing their beak up at the sky.

Christian: Yes. And then, staying completely still, they close their eyes and that combined with their camouflage makes them look like just an extension of the tree.

Ellen: They are become branch.

Christian: Yeah.

Ellen: Don't worry about me. It's just me, a branch on this tree. Definitely not a bird. You can keep moving on.

Christian: So yeah, they do this when they sense something nearby and as long as they stay still, you're probably not likely to see them. They'll peep their eyes open just a little bit to kind of, to see when the threat has gone away. I thought that was interesting.

Ellen: This reminds me of being a little kid and playing hide and seek, and having the idea in my head that if I could not see who was looking for me, they could not see me either. And like just barely squinting my eyes open.

Christian: That's cute. My second point for their ingenuity is their hunting method. So even when they are awake at nighttime, what they're doing is they will kind of go to the lower levels of tree branches and stay still until something gets nearby. So when you see a picture of these fellows, you notice they have these big eyes. So they're really, really good for seeing in the dark.

Ellen: Oh yeah. Good nocturnal adaptation.

Christian: Yeah. So again, another kind of thing to liken them to owls, but they're different in that the eyes aren't framed in the same way. Because with these guys, their eyes are almost bug-eyed. If you see them from directly head-on, you'll see what I'm talking about.

Ellen: Oh, you know what? I have seen pictures of where I know what you're talking about. And it makes a really funny aesthetic because they have the wide, flat mouth and also these enormous bug eyes and it makes them look kind of like they're kind of panicking at all times, just in a state of anxiety.

Christian: Yeah. What they'll do is they'll sit and wait for prey to get nearby, and then once it does get nearby, they will just take off flying after it and just go grab it in their enormous mouth and eat it.

Ellen: So they're eating things like bugs or are they eating like, rodents or what? What kind of things are they hunting?

Christian: So they eat large flying insects. Here's something I wasn't expecting: occasionally, small bats.

Ellen: Oh no!

Christian: Yeah!

Ellen: Oh my goodness!

Christian: Right?

Ellen: Okay. So I guess yes, now that I'm thinking of it, there are probably bats in that area where they live in that are small enough for this bird, which is big, but it's not like a huge bird. Right? For instance, have you seen like the little Honduran bats that like the size of like your thumb? Tiny, tiny little bats that like, sleep in flowers and stuff. It's really cute.

Christian: They don't even need to be that small. I think the ones that that are at the Jacksonville Zoo, like in the jaguar area, like those would fit easily in the palm of your hand.

Ellen: Yeah.

Christian: Those would be fair game for this bird.

Ellen: You said they live in Mexico too, right?

Christian: The very southeastern part of Mexico.

Ellen: Okay. Cause vampire bats live in Mexico, so I wonder if they eat vampire bats. But that's interesting, I hadn't thought of them as eating bats. I would have thought of them as sharing the same prey. Like I would have thought of them as both eating bugs.

Christian: No, so I think bats would be going for smaller bugs actually. Well, the size of bats that this one's going for, it would be going for smaller bugs, cause the bugs that this one is going for are like big beetles, like sized flying insects.

Ellen: That's funny because it seems like they're kind of preying on the bat, so they're getting their food but they're also taking out their competition.

Christian: Two-pronged method there.

Ellen: That's how you can out hunt the bats, is by just eating them.

Christian: If you can't join them, eat them.

Ellen: If you can't beat them eat them.

Christian: That's much better. On to aesthetics, the third category, how pretty they are, how cute they are, how aesthetically pleasing. So for this one I'm giving an 8 out of 10 cause they are a tree.

Ellen: Just am tree.

Christian: I'm very impressed with their pretty feathers and how they look like trees, and of course their wide mouths are somehow endearing.

Ellen: It is kinda cute. A little bit. I think it almost looks like a smile, almost in a way.

Christian: Here in a moment I'm gonna talk about the sounds they make and I think it goes well with that aesthetic. And then lastly, their big eyes.

Ellen: Yeah. That does give them a cute look. I like big eyes.

Christian: Yes. So that's my main scores. I'm going to get into some miscellaneous info. So in terms of conservation status, the great potoo is of Least Concern on the IUCN Red List.

Ellen: Oh very good.

Christian: Their population is decreasing, but not at an alarming enough rate to pose concern. In some rural parts of Brazil, potoo feathers are thought to have the power to ensure chastity.

Ellen: Oh, dear.

Christian: Yes.

Ellen: Oh no.

Christian: So they're hunted for their body parts to be used in ceremonies to ward off seduction.

Ellen: Ward off seduction...

Christian: I can relate to this because I once had a RuneScape subscription.

Ellen: [loses it] Oh my God.

Christian: And of course, you know they're susceptible to things like slash and burn agriculture in the rainforests, that sort of thing. Now, their sound.

Ellen: This is the real bread and butter of the potoo.

Christian: I'm gonna imitate it.

Ellen: Okay. Let me hear it. Can you back away from the microphone a little bit?

Christian: It kind of sounds like, [BWAAA].

Ellen: One more time.

Christian: [BWAAA].

Ellen: There's this video that's been circling around that shows a potoo sound, and the caption on it says it sounds like a frustrated teenager whose mom has just told them that they can't like, go to their friend's house because the sound that they make sounds like, "MMMOOOMMMM."

Christian: So keep in mind the different potoos sound differently, so I'm not sure which one that one was. But yeah, this one, its call is described as haunting, which of course you would mostly be hearing this at nighttime.

Ellen: Oh gosh. That really just makes it worse, doesn't it?

Christian: Yeah.

Ellen: Man, we should have done this one for our Halloween episodes.

Christian: Maybe. Things that predate it include: monkeys...

Ellen: Oh no. How- okay. How does a monkey catch a potoo?!

Christian: So let me describe everything else too. So monkeys, these things called tayras, which are a kind of weasel in that part of the world.

Ellen: But they have short stubby legs!

Christian: I know.

Ellen: They cannot get that high up off the ground!

Christian: Also collared forest falcons.

Ellen: That one makes sense. This one's on brand. This one I approve of, this is fine.

Christian: It leads me to believe, do they go all in on their camouflage?

Ellen: And just like just like...

Christian: "Nope, Nope. Still doesn't see me, still doesn't see me- Ow, shucks! It's got me!" Makes me wonder.

Ellen: Yeah, I have seen the video- we were just watching videos of the potoo the other day and I have seen a video where they do that squinty thing, but then they just very slowly move their head to keep track of whatever they're hiding from. So I wonder if they're just really rolling the dice. Maybe they like, fail their stealth check and just kind of run with it.

Christian: I don't know, because they can definitely fly.

Ellen: Right! Just do that! Just do that.

Christian: I don't know. Maybe the things that hunt them are stealthier. Who knows.

Ellen: A monkey?

Christian: I don't know. And then lastly, they lay a single egg at the end of that broken tree branch that they hang out on. So they don't build a nest, but they do lay one, like if you imagine a vertical tree and the very tip of it is broken off...

Ellen: Trees tend to be vertical. Yeah.

Christian: Yes. Unless misfortune has befallen it. But with this one, imagine at the very end of the trunk, it's broken off and has a bit of a divot. So that's where it would lay its one egg.

Ellen: Just the one?

Christian: Yep.

Ellen: Awww...

Christian: And it doesn't build a nest or anything. And what it does is it covers it with its body, because even when the egg hatches, it's not quite at the coloration it needs for camouflage. But the parent will just kind of cover it with its body and do its "stay still" camouflage to cover it.

Ellen: Oh, gotta protect the beeb.

Christian: Yeah. But here's what's strange: so there's only ever one of the parents doing this at a time. And the problem with this is you can't tell the sexes in the adults. So it's kind of unknown if it's just one of the parents sticking around, or if they're just trading off.

Ellen: Oh, so we don't know like both parents are raising the chick.

Christian: Right.

Ellen: Huh. Well darn cause I was gonna ask you about that.

Christian: I guess this must be a common problem in birds where there is no dimorphism and they do this where they're not doing it at the same time.

Ellen: Sure. Huh. Well shoot.

Christian: Interesting little tidbit, I thought.

Ellen: I guess maybe good moms, maybe good dads, maybe both. Not sure. Oh, and talking about the babies, I did also see a picture of a baby potoo. Like it still had the little fluff on it and it was pointing its nose up in the air. Like it was already doing the defense posture. So it seems like that's something that they learn very early in life and I love that.

Christian: Oh, and I'll add another last bit here: the plural form is potoos.

Ellen: It's not pothrees?

Christian: Excellent.

Ellen: Pofours? I appreciate you teeing up my joke.

Christian: All right. That's all I got.

Ellen: Excellent job. I love this bird.

Christian: Thank you.

Ellen: Thank you for telling us about the potoo. Before we move on to my animal, I would like to take a quick moment to thank our patrons on Patreon, this week I'm thinking Briana Feinberg, Krystina Sanders, the Jungle Gym Queen, and Jacob Jones. Thank you all!

Christian: What animal do you bring us to this week, my love?

Ellen: This week I'm talking about the African giant pouched rat, also known as the Gambian pouched rat.

Christian: That's quite the title.

Ellen: Their scientific name is Cricetomys gambianus.

Christian: Okay.

Ellen: This species was requested by the Jungle Gym Queen in our Facebook group. It's actually been sitting on my list of animals that I've wanted to talk about since like, before we actually even recorded our first episode when I started our species list, and it's just been sitting there and I haven't had an excuse to talk about it yet, so finally somebody requested it and I was able to set it free from the species list.

Christian: Excellent.

Ellen: So I'm getting my information on the African giant pouched rat from the San Diego Zoo, the University of Michigan's Animal Diversity Web (woo woo! Love them) and APOPO.org.

Christian: One more time.

Ellen: APOPO.org. I'll explain that when I get to it.

Christian: Okay.

Ellen: So I'm going to first introduce you to the African giant pouched rat. As the name would imply, this is a large rat. Just the body length, from like the nose to the butt, is about one to one and a half feet.

Christian: Wow.

Ellen: And then the tail is equally as long, adding up to a total length of around 3 feet, which is just under a meter from the tip of the nose to the end of the tail, that's about 3 feet long.

Christian: That absolute metric unit.

Ellen: So their weight is typically around 3 pounds, but they can be up to 9 pounds, which is roughly the size of like a smaller house cat. I said that I heard my cat in the background go "meow!"

Christian: "Wish you would!" Our cat is not of the smaller variety.

Ellen: He's a big boy. Yeah, our cat is definitely bigger than this rat, but this is still a very large rat. This rat has brown fur and a pale underside. They're native to subsaharan Africa and they have a really wide range of habitable biomes, right? So they don't like just live in forests or just live in grasslands. They can live in a lot of different places, pretty much anywhere where they can find shelter. And shelter could be trees, it could be rocks, it could be shrubs, it could be termite mounds, it could be burrows of other animals, pretty much anywhere where they can find somewhere to burrow, they will live there.

Christian: Okay.

Ellen: Their taxonomic family is called Nesomyidae and this is a family of African rats and mice. This is different from the family that we think of as like common rats. So European rats, they belong to a different family, so they're only sort of distantly related to them, but they are still, you know, rodents. The giant pouched rat is obviously much larger than those rats, but it also has much longer limbs proportionally, larger and taller ears, and this was a surprising part: smaller eyes. Like proportional to the body at least, much smaller eyes. They have actually really tiny eyes.

Christian: Weird.

Ellen: It is weird. That's a good segue for me to get into the first category for this pouched rat: effectiveness. Just like your effectiveness, this is physical adaptations that let the animal do a good job of doing its things. I'm giving the African pouched rat a 7 out of 10. It's decent. This is more of a generalist, instead of a specialist. They're not like, highly specialized for anything in particular, but they're a little more adaptable. They are opportunistic omnivores. They will eat pretty much anything. Fruit, vegetables, seeds, nuts, insects, meat, whatever's available. They will take it and they will chow down.

Christian: All right.

Ellen: So the word "pouched" might make you think that it has like a tummy pocket, like a marsupial.

Christian: Yeah, I figured it was probably not the first guess type thing.

Ellen: So the first time I heard of these rats, that was my assumption was that the pouch was referring to like, a tummy pocket of some sort.

Christian: Sure.

Ellen: Or you know how like, otters have little pockets like under their arms and stuff where they have little like, hidden pouches? This is not really that. The pouched part of their name actually refers to pouches that it has in its cheeks.

Christian: Aw, like chipmunks.

Ellen: It's just like chipmunks and it allows it to store massive amounts of stuff in their cheeks, just like a hamster. Although they're not really related to hamsters, so this is another example of convergent evolution.

Christian: Neat.

Ellen: Where they evolved their own little secret mouth pockets. It uses those pouches to carry food, but it also carries nesting materials in its pouches. So when it's like building nests and lining its nest with stuff, it stuffs all that stuff in its cheeks and carries it back.

Christian: That sounds very unpleasant.

Ellen: It doesn't sound fun, but they seem to enjoy it.

Christian: I was just thinking, how much food could I fit in my cheeks?

Ellen: In your human cheeks? How- okay, let's think about it. How many grapes do you think you could fit in your cheeks?

Christian: Four on each side.

Ellen: On each side? That's it? I think you could get up to six on each side.

Christian: I was thinking in terms of Jolly Ranchers for some reason.

Ellen: Okay. How many Jolly Ranchers do you think you could fit in your mouth? Fine, let's go there.

Christian: Five.

Ellen: Five Jolly Ranchers in your mouth and that's it?

Christian: Each side.

Ellen: Okay, so a total of 10 Jolly Ranchers.

Christian: Yes.

Ellen: You know, we've got a whole bucket of Halloween candy in our kitchen. We can test this out right now. We can see how many Jolly Ranchers you can fit in your mouth.

Christian: I'm good. All the listener would hear is [gross slurping sounds].

Ellen: Stop it! Gross!

Christian: Great radio.

Ellen: Now I have to throw the whole episode away. So yeah, they put food in their cheeks, just like a, just like a hamster. It's really cute. They're also pretty good at climbing and swimming. They have that, that really, really long tail that they have, gives them pretty good balance and it lets them do a pretty good job of climbing and running around in the trees. This allows them to access different, hard to reach food so they could climb a tree and get like, fruit for example, and they also can get up to spaces where they can take shelter inside of hollowed out trees so they can like climb a tree and then use a hole in the tree to get inside of it and then use the tree as shelter. Yeah, it's pretty neat. One of my first like, deductions is that they do have pretty small eyes, like I mentioned earlier, and this is actually counterintuitive because they are nocturnal.

Christian: Huh.

Ellen: Yeah. So like you mentioned for the potoo, usually nocturnal animals have pretty big eyes that allow them to take in more light and see better in low light, but they don't, they have are actually really small eyes. So their eyes aren't helping them out much, so they're relying more heavily on their sense of smell for navigation. Yeah, sometimes even if you do see them out and active during the daytime, it seems like they kind of don't actually use their sight at all. They act as though they're blind.

Christian: Weird.

Ellen: It's really weird. It's very strange. But so yeah, they don't have very good vision, but I feel like they kind of make up for it with a really good sense of smell. They're also pretty sensitive to temperature. They're very lean, they don't have a lot of fat on their body.

Christian: Oh, okay.

Ellen: They don't carry very much fat on them, which means that they're really vulnerable to cold and they can have some negative effects from experiencing lower temperatures, but they're also nocturnal and they burrow during the day to avoid the heat of the daytime, which kind of tells us that they're also sensitive to heat.

Christian: Huh.

Ellen: Yeah. So they're a little bit picky about their temperatures. They don't really do particularly well in either very high or very low temperatures. They kind of need a more temperate environment.

Christian: And these are found in Africa?

Ellen: Africa. Central and southern Africa.

Christian: Huh. Okay.

Ellen: Yeah, it's just interesting. They're more temperature sensitive than you might have assumed them to be. So my last kind of point that I gave them for effectiveness is that, like many other rodents, they are prolific breeders. So an adult female rat can have up to 9 litters per year of up to 5 offspring per litter.

Christian: Oh geez.

Ellen: An adult female pouched rat is capable of producing up to 45 pups per year.

Christian: Yikes.

Ellen: It's so many. This is a rodent thing, right? Like when you're kind of little, you might die- well, you're probably going to die. So you just have all of the babies to kind of make up for your mortality rates.

Christian: Oh man.

Ellen: So yeah, they have lots of babies.

Christian: So what keeps them in check?

Ellen: I mean things eat them, you know. Like birds of prey will eat them.

Christian: Oh, okay. I was gonna ask if there's anything in particular or just whatever.

Ellen: They're not the favored prey of anything in particular. There's nothing that really like, seeks them out. But I mean, birds of prey will grab them. You know, stuff like that. So that sums up the effectiveness for them. Moving on to ingenuity. This is where the pouched rat shines. They have ingenuity in the bag. I'm giving them a 10 out of 10.

Christian: Alright. Hehe...

Ellen: This is a very, very smart little dude- What?

Christian: It's got it in the bag. Pouched rat. Ha.

Ellen: Oh my God. Anyway, so like I mentioned earlier, they like to burrow, they take shelter in naturally occurring crevices. These could be hollowed out trees or termite mounds, anything like that. They can also dig their own burrows in the ground if there's none available. Once they've kind of got their burrow situated, they will also construct systems of tunnels. So it will give them multiple openings for entering and exiting as well as chambers for nesting and having babies and stuff like that. They also hoard. They're major big time hoarders. They hoard real bad.

Christian: Oh boy.

Ellen: So the pouched rats will stash food in their burrows even when food is plentiful and there is no shortage. So a lot of animals will kind of stash food for like the winter, or like a seasonal thing for when food is low. But pouched rats will hoard all the time no matter what.

Christian: I don't know who that sounds like.

Ellen: Puppy, who hoards treats in our couch.

Christian: I've got a different opinion on that now.

Ellen: What?

Christian: I think she's just trying to hide the treats she doesn't like. She's trying to spare us our feelings.

Ellen: Oh is she being nice to us? That's probably true because I haven't seen her do it with the new treats that we got her.

Christian: "This is bad. Get it out of my face."

Ellen: Well, so the pouched rats will stash anything all the time.

Christian: Okay.

Ellen: Yeah. They just are big time hoarders, which I actually thought was pretty smart of them because like, I dunno, I felt like it was a a good example of preparation and thinking ahead. Thinking longterm. Right? Like, better I'm safe than sorry.

Christian: Yeah.

Ellen: Another smart thing that they do is that, since I mentioned that they are kind of susceptible to cold temperatures, when it starts to get chilly, the rats will huddle together in their burrows to stay warm. They're usually pretty solitary, but when it gets chilly, they can all kind of form a huddle and stay warm.

Christian: Those winter cuddle feels.

Ellen: It is. Yeah. It's, you know, it starts to get cold, boyfriend weather starts creeping in...

Christian: That new season of that show you watch is now available on Netflix.

Ellen: It's time to bust out the sweaters and the blankets and have yourself a good old cuddle. Another thing that they do is that when they're threatened, they puff up their cheeks with air to make them look bigger. They inflate their cheeks.

Christian: I really want to see you this.

Ellen: It's really funny because if you can imagine like, you're squaring up with like some human person that is like, intimidating you and then as you're about to fight, all of a sudden they just blow their cheeks up with air.

Christian: So you're in the basement of this tavern, right? The owner has hired yet another adventurer to deal with the giant rats in the basement. The party of four to six people come down the stairs...

Ellen: And all of the rats puff up their cheeks really big. Are you still gonna fight them? No, you're not. So yeah, I thought that was a smart thing that they do. But the last thing I want to talk about for their ingenuity was kind of the main reason I wanted to talk about the African giant pouched rat. These are called HeroRATs.

Christian: Okay.

Ellen: HeroRATs are used by the organization APOPO, that I mentioned at the top. So I'm getting all of my information for this little segment directly from their website, APOPO.org.

Christian: Okay.

Ellen: Now APOPO is an acronym based on their Dutch name, because the organization was founded by a Dutch person, so the organization is of Dutch origins, so that acronym is based on their Dutch name, which translates to, in English: Anti-personnel Landmines Detection Product Development.

Christian: Uh oh!

Ellen: This is the bomb squad.

Christian: Does this end poorly for the rats?

Ellen: No! No it doesn't. So African giant pouched rats, with their keen sense of smell, incredible intelligence, and high motivation for reward are prime candidates for a specialized task force tackling a pretty daunting task, which is landmine detection and extraction. So the rats are put through a 9-month training course, which I'm going to affectionately refer to as rat college, and using clicker training and treats to associate the scent of explosive materials with receiving a food reward. Their favorite is bananas, they love bananas and they will fill their cheeks with bananas and it's really cute. In order to graduate from rat college, they have to pass a final exam, which consists of detecting real, actual deactivated landmines. So they will set up this field and the trainer will deploy- well, not deploy, the trainer will hide all of these landmines in this field and the rat has to cover the entire field and point out to its handler where the mines are. And if the rat misses any of them, if it misses one land mine, the rat does not pass rat college and doesn't get its rat diploma.

Christian: Strict but fair.

Ellen: So, it's a pretty rigorous course and the rats have to be extremely accurate to pass and to be used in the actual real life field. What this results in is a rat that can, after completing their training, the rat is able to search- this is a direct quote from their website, "an area the size of a tennis court in 30 minutes." And this is a task which would take a human with a metal detector up to four days to finish. So they're working much faster than humans. Now you're probably wondering why- how the rat is doing this without exploding.

Christian: Yeah. Cause for a second, you know, you mentioned this was- what, the landmine detection and... something else, it was like detection and...

Ellen: Extraction?

Christian: Detection and extraction, as opposed to detection and detonation.

Ellen: No, so actually the reason why they use rats instead of dogs, for example, is that rats are small enough that they're too light to trigger the detonation device of the landmine.

Christian: Okay.

Ellen: Yeah, they're too little. So they're like as smart as dogs, if not even smarter, but they're little enough to be able to navigate the field without setting off any mines.

Christian: See, then you just gotta train chihuahuas.

Ellen: I would rather not, personally. So using HeroRATS, APOPO has detected and destroyed over 107,000 land mines and unexploded bombs.

Christian: Wow.

Ellen: Yeah. This has resulted in restoring over 23 million square meters of land to safe use by humans in Cambodia, Angola, Tanzania, Mozambique, Vietnam and Laos.

Christian: Oh, okay. So they were deployed into Asia as well.

Ellen: Yeah. And they've also worked on using the rats in South America. Central and South America.

Christian: Okay.

Ellen: You know, they're native to Africa, they're already suited to these sort of warmer temperature, like close to the equator sort of areas. So it's pretty easy to pick them up and transport them to areas with a similar climate and they can do pretty well there too.

Christian: Cool.

Ellen: There's one other thing that APOPO uses them for other than detecting landmines, and that is sniffing out tuberculosis. They will give these rats human samples, that will be things like saliva, mucus, stuff like that. And it takes a HeroRAT only 20 minutes to sniff through a hundred samples. The same task would take a human lab technician using traditional methods, again, up to four days.

Christian: Wow.

Ellen: So they're moving through way faster than a human would be able to work through these samples. So the HeroRATs have screened, according to their website, over 570,000 samples, detected over 14,000 cases of tuberculosis, and increased clinic detection rates by 42%.

Christian: wow.

Ellen: Yeah. So these rats are really doing the work out there.

Christian: It's kind of a spin on the lab rat idea.

Ellen: Right, yeah. So, you know, kind of a big selling point of this organization is that they treat the rats very well. They pride themselves on, you know, offering the rats really good rewards and taking really good care of them. And there are a lot of videos of kind of behind the scenes of the organization, and you can see where they keep the rats and it just seems like the rats are having a good time.

Christian: I'm picturing a rat in a lab coat sniffing Petri dishes.

Ellen: Like the rat has like a little uh, safety goggles on. The rat's got PPE and close-toed shoes and its hair tied back in a ponytail.

Christian: "No! No, Dr. Whiskers! Don't put the sample in your mouth!" "I bring back? I bring back."

Ellen: "Oh, I take to burrow? I hoard." So no, they don't wear lab coats, but what they do wear that's really cute is they wear harnesses and leashes because the handler, you know, has to be able to bring them back. Right? So they wear a little harnesses and it's pretty cute.

Ellen: How nice.

Ellen: It is very cute. So yeah, that's the organization APOPO. Like I really recommend checking them out because they're doing some really, really good work and I just love these rats. These are great. Good boys. And that brings us to our final category for the African giant pouched rat: aesthetics. I give them a 6 out of 10. They are pretty cute. I think rats are cute in general. I like rats. I used to have pet rats. They're great. They were obviously not the giant pouched rat, they were just regular old rats you get at the store. I think they're adorable. They're just really cute. Now, the African giant pouched rat I think is a little less cute than the standard-fare rats.

Christian: Why's that?

Ellen: It has smaller eyes and it just has like pointier ears and that kinda messes with the vibe for me personally. They're also a pretty plain in their appearance. They're just kind of a solid, like sandy brown color, you know? They don't really have any interesting markings or anything. Just a 6 out of 10. They're pretty cute. Most people say that they don't like the tail because it is all scaly and bald.

Christian: Yeah, it's weird.

Ellen: I am personally not bothered by it at all. I don't have any qualms about it. But during the time that I worked at PetSmart and I worked at one that did sell like, fancy rats that you would keep as a pet and every single person I think that had any sort of negative feelings about rats was kind of grossed out by their tail.

Christian: I guess it's so uncommon in mammals to have an appendage like that.

Ellen: Oh, we just talked about, I think it was the quokka that we talked about that had a long naked tail.

Christian: Really?

Ellen: I think so. Yeah. The quokka has like a long naked tail, like a rat.

Christian: Well, I'll stop talking about my hangups. What else you got?

Ellen: Miscellaneous information, their conservation status is of least concern. Pouched rats can feasibly be kept as pets due to their high trainability and their adaptability. So it lets them kinda thrive in captivity. They do okay. Now of course, this is a massive rat that you're keeping in your house, right? This is a rat the size of a cat. So you're going to need like a big cage and being a rodent, their teeth are constantly growing and they never stop, so you have to be providing them with things to chew on to grind their teeth down. So yeah, they're like super high maintenance for a rodent. Right? I would say go get a fancy rat cause they're much better pets. But actually importing pouched rats into the USA was banned in 2003 after an outbreak of monkey pox, which pouched rats can carry and spread to humans.

Christian: Huh.

Ellen: Yeah, they can be a carrier of this disease. However, in South Florida, some escaped pets have established invasive wild populations.

Christian: This has gotta be like the fourth or fifth time.

Ellen: Florida is such a hotbed for invasive species. There are so many animals that come in here. You know, I feel like people just bring in all of these, it's not just like exotic pets that people bring in, but it's like little, like bugs and frogs and stuff that come in on plants. Right?

Christian: Yeah.

Ellen: And then they fall off and then Florida just has that like perfect tropical, humid environment where just a lot of things are able to really take off here.

Christian: Yeah, they might as well just handing them a brochure, like welcome to Florida.

Ellen: Please establish breeding populations in our swamps and forests. Please do it.

Christian: Nothing here to eat you? Lucky you.

Ellen: That is the African giant pouched rat.

Christian: Well thank you hun, that was very interesting.

Ellen: I love these friends. I thought they were great. Well yeah, so thank you very much for checking us out. I really appreciate you spending this time with us. You guys are so nice. I've made so many awesome friends through doing the show and you guys interacting with us and engaging with us. You guys are really delightful on social media. We're on Facebook, Twitter and Instagram. Just search the title of the show. You'll find us. If you have an animal species that you want to hear us review, you can submit those to us. My email address is ellen@justthezooofus.com. A transcript of this episode and all of the other ones will be made available at justthezooofus.com, and our final note, thank you to Louie Zong for letting us use your song "Adventuring" off of your album Bee Sides, we really love it. Go check out Louie Zong. His music is so good. It's all great.

Christian: It's been the the best soundtrack to our little adventure here.

Ellen: It has been, and a lot of times we play his music just kind of like out and about in our house, eating dinner, cleaning the house. It's just, it's really nice. So go check out Louie Zong. That's all I have.

Christian: Well, thanks everyone.

Ellen: Thank you! Byeee!

Christian: Bye.

27: Sentry Dragonfly & Leafy Sea Dragon

Ellen: Hey. You.

Christian: Me?

Ellen: You're finally awake. This is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast in which we take your favorite species of animals and we review them and rate them out of 10, and this week we're bringing you: dragons. Christian and I are not zoological experts, but we do a lot of research to get ready for the show and make sure that we are presenting you information from trustworthy resources. Really, really quick before we get started in the show, I don't normally put announcements at the top, but this is a big one: If you are listening to this and you live in Jacksonville, Florida, and you would like to hear us do this at your face in real life, in person, you can come see us do a live show at Cultivate on Saturday, November 30th. Tickets are available online, so come check us out.

Christian: Yes, it will be very good. I promise I don't have a radio face.

Ellen: Oh, so you are saying like, I promise I'm very attractive and handsome.

Christian: Of course! No, I wouldn't go that far, but...

Ellen: I promise I'm very pleasant to look at that. Anyway, so that was my little announcement section, so on to the dragons.

Christian: Alright babe, who's up first this week?

Ellen: Me. It's my turn.

Christian: Okay.

Ellen: This week I have the absolute pleasure of reviewing the sentry dragonfly, also known as the Australian Emerald dragonfly.

Christian: It sounds pretty.

Ellen: The scientific name is Hemicordulia australiae.

Christian: Excellent name.

Ellen: Yes. So this species was submitted to us by our new friend Benjamin Lancer. A while back, I praised Alyssa Años for submitting like, the best species request ever where it was just an email where like. The body of the email was just the word "quokka" and that was it, and I was like, that's the best request ever. This request was the best request ever and it was the exact polar opposite of that. So Benjamin reached out because Benjamin researches these dragonflies specifically, in a laboratory setting. Earlier I mentioned that we're not experts on these animals, but Benjamin is.

Christian: Yay!

Ellen: So all of the details that I'll be getting into are all from our buddy Benjamin.

Christian: Nice.

Ellen: Yes. So Benjamin Lancer is at the University of Adelaide's Visual Physiology and Neurobotics Laboratory, so I'm mostly going to be paraphrasing the treasure trove of information he sent- he was so kind to send to me. To introduce you to this dragonfly, this is going to be kind of an introduction not only to this dragonfly, but to dragonflies in general if you're not very familiar with them. This dragonfly is about five centimeters, or two inches long and has a wingspan of about seven centimeters, or just under three inches.

Christian: Okay.

Ellen: It's big for an insect, right? Bigger than most insects you find.

Christian: Sure, but probably about what one thinks of when you think of a dragonfly.

Ellen: Yeah. If you've never seen a dragonfly, what they look like is most of their length is made up of their very, very long, skinny body and that is all abdomen baby. Like it's all like, kind of what you would think of as their tail, and they have two pairs of wings. One of them is in front of the other and the one closest to the head is slightly larger. And when they are at rest, they hold those wings out horizontally. This is as opposed to the damselfly, which holds the wings vertically at rest. So this is one of the ways you can tell a dragonfly from a damselfly, is whether they hold their wings out to the side or upways. Now, this dragonfly in particular is located, as the name would imply, in Australia. It can also be found in the surrounding islands and New Zealand.

Christian: Okay, cool.

Ellen: So you're not going to find them where we live. We have dragonflies, but we don't have this dragonfly.

Christian: Okay.

Ellen: Dragonflies makeup the infraorder Anisoptera, of which there are about 3,000 recorded species. There's so many dragonflies.

Christian: Makes sense.

Ellen: There's a lot. So we have some in our backyard, but they are definitely not this one. In their genus there are about at least 13 known species, but the one I'm specifically talking about, their common names include the sentry dragonfly and the Australian emerald dragonfly. Let's get into their ratings. If this is your first time joining us, we divide our ratings into three categories, the first of which being effectiveness, which we define as the physical attributes of the animal that give it a sort of competitive edge over other animals that make it really good at doing the things that it's trying to do and accomplishing what it's going for. So just because they're called "dragonflies," dragon is in their name, does that necessarily mean that they are these legendary killing machines, menacing the skies and striking terror into the hearts of their utterly defenseless prey? Yes, it absolutely does. 10 out of 10. Dragonflies are believed to be some of the world's most successful predators, securing 95 to 97% of their attempted prey captures.

Christian: Oh okay.

Ellen: To put this into context, the highest vertebrate predator's success rate is 85% by African wild dogs.

Christian: Huh.

Ellen: Now, African lions, between 20 and 30%. Absolute garbage.

Christian: Yeah, I remember hearing about those.

Ellen: But so the dragonfly almost always catches what it's trying to catch. Almost every time. Very, very close to 100%, like pretty much as good as it gets as far as predators.

Christian: Can I take a stab at why?

Ellen: Best of luck.

Christian: Is it their aerial acrobatics?

Ellen: Sort of.

Christian: Okay.

Ellen: Sort of. Related to their aerial acrobatics, they are very powerful fliers. So as I mentioned a minute ago, they have four really powerful wings, but something that is unique about dragonflies and their wings is that they have the ability to control each wing individually, separately from each other.

Christian: So, not even like, the separate pairs but each one individually?

Ellen: Each individual of the four wings, they can move separately from the others.

Christian: Wow.

Ellen: So there's this sort of concept of what's called a stroke plane, which is the axis along which the wings are aligned. Dragonflies, like other insects, can rotate their wings to flap in different directions. But the dragonfly is able to change the angle of each of its four wings. So this is what allows it to pull off some of those really crazy aerodynamic moves. So they can hover, where they're just flying completely still in the air, they're just hanging there like they're frozen in the air, they can make sudden sharp turns and even 180 degree turns just on a dime.

Christian: Wow.

Ellen: Yeah. It's really crazy to see them do this, but it's because of how much control they have over their wings. So as a really cool little added perk of those wings, dragonfly wings are completely covered in microscopic spikes. They're called nanopillars, and the nanopillars shred bacteria to bits, preventing it from being able to survive on the surface of the wing.

Christian: Oh, okay. Oh, so it's like really, really small.

Ellen: Yes. It's really just for preventing bacteria from growing on the wings.

Christian: That's one way to do it.

Ellen: Isn't that cool?

Christian: Huh.

Ellen: Yeah. So as amazing as their wings are, the wings do have one weakness: Water.

Christian: Huh.

Ellen: So when the wings are wet, they are too heavy to flap and the dragonfly cannot take off. So this is not really ideal for a species that lays eggs in water, and therefore it needs to be hanging around water quite a bit. Yeah. So that was just, that's just their one sort of weakness, I suppose.

Christian: What parts of Australia are these things in? Is it like the whole continent or...

Ellen: It's more like near the coasts, like along riverbanks and stuff like that.

Christian: Oh yeah, I guess that makes sense, cause they need that to breed. Okay.

Ellen: So the next thing I want to talk about is their eyes. So dragonflies, when you look at them, most of their face is the eyes, right? The eyes are kind of like two hemispheres on the front of the head. So dragonflies have compound eyes that are very large. So relative to their body size, they're among the biggest eyes of all of the animals. Which, if you remember last week, I also said that about the vampire squid. So I don't know, I don't have access to the numbers needed to make those calculations. But if anybody does, if anybody out there can run the math to see which has bigger proportional eyes, the dragonfly or the vampire squid, please figure that out and hit me up. Please do the math for me. Thank you. So we've talked about compound eyes on the show before, way, way, way back when we talked about the praying mantis. But let's go over them one more time because that's been a really long time and our audio quality wasn't very good back then, so let's do it again.

Christian: Alright.

Ellen: So the compound eye is made up of very, very many little teeny tiny miniature... Kind of like eyes, and those little teeny tiny eyes are called ommatidia.

Christian: One more time.

Ellen: Ommatidia. O-M-M-A-T-I-D-I-A, and that is the plural of the word ommatidium.

Christian: Okay.

Ellen: So one of them is an ommatidium, many of them are ommatidia. And they all function together to make the visual image that the dragonfly is seeing. So a lot of people kind of assume that a compound eye made up of many, many eyes means that the insect can see very, very well. It's not necessarily true. So the ommatidia don't actually produce very detailed images. So the metaphor that Benjamin provided when talking about the compound eye is that of an image on a computer screen, where each ommatidium gives the dragonfly one pixel that together form a whole image, but it's in pretty bad resolution. It's like a pixelated, not very clear image. You're not going to get a lot of detail out of it. So the strength of the compound eye is in field of view rather than detail. So the dragonfly can see in nearly 360 degrees, eliminating their blind spot and making them very, very hard to sneak up on. So they can't see itty bitty details, but they can see everything. But with that being said, the real strength in the dragonfly's visual system is in its processing power, in the way that its visuals are connected to its brain and the way its brain processes that information. Which brings me to our next category: ingenuity, which we define as clever behavioral adaptations that an animal has that make it good at kinda outsmarting the obstacles in its way every day. For the Australian Emerald dragonfly. I'm giving it a 10 out of 10 for ingenuity.

Christian: Okay! That's surprising for an insect.

Ellen: Yes. It's very surprising for an insect. This is our friend Benjamin's area of expertise, and kind of the whole reason for requesting this dragonfly. This dragonfly has, at sort of a cursory glance, a very simple brain. It only has about a million neurons, which sounds like a lot, but to put it in perspective, a human has 86 billion neurons, so a human has 86,000 times more neurons than this dragonfly.

Christian: Alright.

Ellen: It seems like a very simple little brain, seems like not a lot going on. However, there's one neuron in particular that Benjamin studies in the dragonfly called the Centrifical Small Target Motion Detector 1, or CSTMD1, which he does by placing electrodes inside the brains on the individual neurons of the dragonfly.

Christian: Wow.

Ellen: I got stressed out just thinking about that game of Operation. And then after putting electrodes on the brain of the dragonfly, presenting the dragonfly with stimuli and then measuring the response of the dragonfly's brain to the stimuli. This neuron, CSTMD1, has the job of keeping track of moving targets by predicting where the target is going and focusing its visual processing attention there at the spot where the target is going.

Christian: Okay.

Ellen: The dragonfly doesn't chase their prey in the sense that other predators do by following behind the prey, catching up to it based on speed, and that's kinda it. Right? So instead, the dragonfly predicts where its prey is going, and flies there instead, and intercepts the prey as it travels along a path.

Christian: Does this imply their prey are usually also flying?

Ellen: Yes. They hunt other small insects like mosquitoes, flies, basically any- they could even hunt like smaller dragonflies. Basically any flying insect that's small enough for them to eat.

Christian: So that predictive capability is... Even for computing, is pretty complicated.

Ellen: It's extremely complicated and it's very surprising that they do that with such a small brain. But so yeah, they intercept the prey as it travels along a path. I mean, this is so complicated that this is something that even like, I can't do. Which you know, having played video games with me that require firing slow-moving projectiles at moving targets.

Christian: Which is why you play hitscan.

Ellen: I can't! But you know, if you've ever like, tried to throw a ball at a moving target or something, it's very, very hard to factor both your target's trajectory in your own and accurately hit something with a 97% accuracy rate! That's insane!

Christian: Well, what's also impressive, you know, when you're talking about a ball or something, you know, the target might be moving along a linear path at a set speed. So it's somewhat easier to predict, but with something like trying to chase down a mosquito, that mosquito could go in any direction at varying speeds. So that's just more, more impressive in my mind.

Ellen: Yeah, it's insanely cool. So now, whenever- I feel like whenever I see dragonflies, like zipping around in our backyard, I'm imagining the little floating math equations around their heads. Simple geometry. When we talk about focusing on a target, what the dragonfly is doing when it's focusing on a target, is it is amplifying visual responses from the target and suppressing responses from anything that is not the target. Does that make sense so far?

Christian: Yeah.

Ellen: So instead of amplifying everything, they're only amplifying what they're interested in. So you're not amplifying all of the sort of noise around it, ignoring the entire world outside of that target and pretending everything else in the world does not exist. This is called giving it absolute attention. Anything other than that mosquito that they're after might as well not exist. So this means that even if some unexpected stimulus, like say like something falls out of a tree or something moves in the water below them, something like that, they resist the distraction and stay perfectly on trajectory.

Christian: Nice.

Ellen: Even if that stimulus is more noticeable than their target of interest. Right? So say they're flying after a mosquito and then like, a fish jumps out of the water or something, that's way more noticeable than a mosquito flying around, but they're on target so they don't get distracted. So this is different from attention in, for example, vertebrates, which rather than absolute attention, is something called "weighted attention," which responds to stimulation from multiple sources by averaging out the intensity of the responses. In the case of weighted attention, even just the existence of other stimuli, regardless of their importance, impacts the amount of attention given to the task at hand. So imagine that there's like, a lot of people talking, you're in a crowded room, but you're trying to have a conversation with somebody in particular. Even though you're paying attention to that person and you're giving them, to the best of your ability, all of your attention, you can still kinda hear the people around you, right? It's still a little bit more difficult for you to focus on them cause there's just a lot going on, right?

Christian: Right.

Ellen: You're going to get distracted, there's just- even though you're focusing on them, the other things going on around you are factoring into the amount of attention you can pay to the conversation you're trying to have. The dragonfly is not like that at all. The dragonfly can just pretend the rest of the world doesn't exist.

Christian: Cool.

Ellen: So the ability of the dragonfly to entirely filter out all distractions allows them to focus completely on their prey and pull off all the crazy trajectory calculations that they need to do while they're zipping around in the air. So this is particularly useful for two reasons, the first of all being that dragonflies are most likely to be active and hunting in these very visually noisy areas. So there's lots of foliage, lots of vegetation, other wildlife around. So hunting insects in these kinds of settings is a little bit like playing where's Waldo, except everything is moving and Waldo is less than half an inch long, and also your vision is in 144p. It's very, very difficult to do. So having that ability to sort of laser focus is very important in this setting. So the second reason is that dragonflies largely hunt prey that groups together in swarms. So when there are hundreds of possible targets buzzing around, it's really easy to get confused and lose track of them, which is why the mosquito swarm in the first place. They do this on purpose. This is a tactic to confuse predators. But dragonflies are immune to the confusion response.

Christian: Wow.

Ellen: They cannot be confused. So what that means is that when the mosquitoes are swarming and there's a whole bunch of them in a small area, that makes it more difficult for them to evade because they're densely crowded, right? So since the sentry dragonfly doesn't get confused by those large numbers, what they're essentially doing is they're turning that swarming tactic against the mosquitoes and turning it into a weakness instead of a strength. Because now, instead of having the benefit of flying around and confusing your predators, now you've just crowded yourselves and made it more difficult for you to get away.

Christian: So it picks out a target. Does it just keep following that target or does it reassess like, "oh, wait a minute, there's an easier target in the swarm"?

Ellen: I don't think it really needs to do that. Like I don't think it needs to factor in easier targets, because once it's kind of locked on, it's probably going to get what it's after.

Christian: I guess if it's chasing a mosquito and it runs into another mosquito, you know that kind of thing.

Ellen: I'm sure it wouldn't turn it down. Free meal I guess.

Christian: Just like, "No, not this one. I want that one."

Ellen: I don't know. But that's a pretty funny idea, that like one literally flies directly into its mouth and it just spits it out on the ground. Like, that's not the one I wanted. So what you are probably thinking is that, well, what if the dragonfly is hyperfocused on a mosquito, it's chasing down a mosquito and what it doesn't notice is a bird swooping down to catch it, right? Like what if it's ignoring threats because of its sort of tunnel vision?

Christian: Right.

Ellen: Fret not for our dragonfly friend. The dragonfly is able to prioritize targets to focus on and switch between them, thanks to our new favorite neuron, CSTMD1. This essentially gives them kind of the best of both attention styles, providing them the distraction-free hyperfocus of absolute attention and the responsive flexibility of weighted attention. So yes, they can switch the things that they're focused on.

Christian: Okay.

Ellen: But the things that they are focused on, they are 100% focused on. Nothing else exists to them.

Christian: Yeah, I wouldn't describe it like that then, cause it- they are aware of everything else around it.

Ellen: So that's kind of the mystery of this neuron. That's why they're studying it.

Christian: Okay.

Ellen: Because nothing else that has this type of completely focused attention, nothing else is able to switch targets like a dragonfly. They don't know why. They don't know why it can do that. So that's why they're studying it, to figure out why it's able to switch targets like that. It's kind of a mystery.

Christian: I have a theory.

Ellen: Okay, let me hear it.

Christian: Two brains. One body.

Ellen: Okay...

Christian: That's it.

Ellen: Great job Christian.

Christian: I guess in my mind I'm imagining some sort of like, two creatures fused into one, one is concentrating on like a particular thing and then the other one's concentrating on everything else. It's like my... Two headed dragon! There it is.

Ellen: Perfect. Alright. Headcanon accepted. So Benjamin actually said that kind of the hope for their lab's research is to figure out how the dragonfly's very simple brain is able to pull off such insanely complicated and adaptive processes, and what they want to do is they want to apply those concepts to artificial intelligence.

Christian: Ah, okay.

Ellen: To do things like making self-driving cars safer, make them better at, you know, like sensing targets and making changes to their behavior based on what they're focused on.

Christian: Hmm. That's interesting.

Ellen: Yeah, I thought that was pretty cool. I thought you would like that.

Christian: Yeah. That's awesome.

Ellen: So all this is really cool, right? They can hyperfocus on things, they can switch what they're hyper focused on, it's all really awesome. But wait! There's more. There's even more cool stuff the dragonfly does. They have this really awesome hunting strategy. Besides the interception strategy, another really cool thing that they do is that they approach their prey from below, so they're staying within their prey' blind spot until they're close enough. So they know where their prey can't see them, and they come from that angle.

Christian: Okay.

Ellen: That's pretty smart, right? Because you have to understand your prey well enough to know where it cannot see you.

Christian: I wonder if dragonflies also have a weakness in that angle.

Ellen: They don't really have a blind spot, but they have another way that they sneak up on each other.

Christian: Ah, okay.

Ellen: So when male dragonflies fight each other, they can fight each other over territory or mates or something like that, and when that happens, you end up in a real predator vs. predator situation, right? Like you have like two unstoppable, perfect killing machines in a dog fight to the death, right?

Christian: Yeah.

Ellen: It's kind of two champions enter, one champion leaves. Usually they will actually end up not fighting. They will size each other up, dance around each other a little bit, do some cool moves in the air, kind of show off a little bit and be like, look, I'm so much stronger than you. And then one of them will chicken out and leave. So they will usually opt not to actually physically fight.

Christian: Okay.

Ellen: However, if neither of them back down and it comes down to it, they will escalate to violence and they will use their own weaknesses against each other. So, not having a blind spot, they sneak up on each other by using an illusion. It's called motion camouflage. What it means is that they fly on a path to intercept the target in such a way that from the target's perspective, their position doesn't change. It stays in the same spot over the target's retina. Does this make sense?

Christian: Oh, yeah... Yes.

Ellen: So it's not moving from like, left to right, or up or down...

Christian: Relative to its prey.

Ellen: Relative to its target that it's hunting down. It's not changing position.

Christian: Okay.

Ellen: So they don't appear to be moving to their target. So the target doesn't notice them, and ignores them until they're too close to escape.

Christian: Interesting.

Ellen: Yes. Is that not crazy? It's like they know, I'm hunting down another dragonfly. It has bad depth perception because I also have bad depth perception.

Christian: So the thing with that, not moving relative to each other, that would be observed from both of them, though. But I guess the one initiating the attack is already focused on the dragonfly and understands that's what's going on.

Ellen: Yes.

Christian: Okay.

Ellen: It's like, I'm attacking that dragonfly. I'm going for it.

Christian: To me, I know it doesn't look like it's moving, but I know what's going on cause I'm the one initiating this. The one initiating the attack is focused on it and the other one just doesn't know yet.

Ellen: Yeah. Hasn't noticed it.

Christian: Okay.

Ellen: So yeah, I thought that was just really, really cool.

Christian: Yeah.

Ellen: It knows the pitfalls of its own visual system, so it knows how to... It knows how to use that to its own advantage. So once the dragonfly has caught his rival, their combat strategy against each other is to grab the opponent's tail and just yeet him down into the water below. Cause they're usually fighting over water.

Christian: Yeah...

Ellen: So they just pile drive them down into the water below, which as I mentioned earlier, that can be a death sentence.

Christian: Sure.

Ellen: It can kill the other dragonfly because if they get down on the water, their wings get too wet and they can't take off. And if they're not able to like, climb out of the water or something so that their wings can dry off, then that's just it.

Christian: Something will probably eat them.

Ellen: A frog, a lizard, a fish, something like that will probably get them before they can get out of the water. The last thing that I wanted to talk about about their mating and their ingenuity in their mating is my favorite thing ever, that if a male dragonfly is attempting to court a female who is not interested, the female will suddenly drop to the ground, falling out of the sky, faking her own death...

Christian: Womp womp...

Ellen: To get out of a bad date. We've all been there, girlfriend. This is a relatable dragonfly who has just faked her own death to get out of date.

Christian: Yikes...

Ellen: Yup. So those are all the absolutely mind-blowingly cool stuff about dragonflies that I learned from our buddy Benjamin Lancer.

Christian: That's awesome.

Ellen: Yeah. It's just so surprisingly complex, all of the insane things that are going on in a dragonfly's brain, and he said that their brains are the size of a grain of rice, and they can pull off all of these insane like- motion prediction, they've got trajectory calculations, they've got stealth, they've got illusion, they just have so much. And they're even thinking about like, I know what kills me. I'm going to use it to kill the other one of me. Just, I can't, I can't, I can't. It blows my mind if I think about dragonflies too much. This brings me to my last category for the Australian emerald dragonfly: aesthetics. I give it an 8 out of 10. This is a pretty dragonfly. It has this long, black-and-yellow segmented abdomen. I think it looks like bamboo, maybe like aged bamboo, how it's got like a black and yellow coloration to it. So in maturity, their eyes turn from brown to bright green, which is where they get that name, Australian emerald. Like all dragonflies, the shape of their body and those four wings- and the wings look like glass, right? They're completely transparent. They have those veins all throughout them that make them look kind of like... I say stained glass, but they're just clear. They're not colorful or anything.

Christian: Yeah.

Ellen: I think it makes them look like a really cool futuristic spaceship.

Christian: Sure.

Ellen: And sometimes, when you see them flying, their wings are arranged in such a way that they kind of look like an X-wing.

Christian: Ha, yeah. I can see that.

Ellen: So yeah, that's my 8 out of 10 for their aesthetics.

Christian: Nice.

Ellen: I'm gonna wrap up with some miscellaneous information. Their conservation status is of least concern. They're fine. Benjamin really wants people to know that dragonflies cannot sting you or hurt you in literally anyway.

Christian: Oh good.

Ellen: There's nothing they can do to you. He says that they can bite, but it does not hurt, and it is very rare. They can bite you, but I mean, there's nothing to it. He said that he works with them every single day and has been bitten like once or twice. So it's really not a thing that they do. It's not something that they use for self-defense. So they have these two appendages at the end of their abdomen, they look like a pincer, so they look like something that would be able to pinch you or something, but it's actually just a little grabby bits and all they use it for is to hold on to each other when they mate. So it's not anything that they could use against you in any way. They're totally fine. Leave them alone. Like they're not going to hurt you in any way at all.

Christian: Cool.

Ellen: You actually want dragonflies around. Like they're awesome to have around. I love having them, because they eat all the mosquitoes in our backyard.

Christian: Yay!

Ellen: We have blue dashers, we don't have this type of dragonfly. So another thing that Benjamin wanted to kind of reiterate is that this neuron that he studies has only been recorded in this species of dragonfly and another one that's closely related to it that's in the same genus, but it's likely that they exist in many other types of dragonflies, they just haven't been recorded yet.

Christian: Nice.

Ellen: Yeah. So that's why I wanted to specify that that was the species I was talking about in this episode, because this information is particularly- I can only like confirm that it's this species has this, others probably do, this is just the information that is available to me at this time.

Christian: Cool.

Ellen: Yeah. So in summary, they are the perfect hunter and it is by nothing short of the merciful hand of mother nature that made them too small to eat humans that we survive to this day. Because if they were big enough to eat us, they would, and we probably never would have made it past like an early primate stage.

Christian: Well, you can thank the oxygen content of our atmosphere is that is the main limiting factor in the size of bugs and insects.

Ellen: I did see that there was this ancient prehistoric species of dragonfly that had a two foot wingspan.

Christian: Yikes.

Ellen: It's pretty big. It's still not big enough to eat a human, so I think we would still be okay.

Christian: I mean, I still- you probably would want to avoid the bite of that even more so.

Christian: Yeah... Although I don't know. I don't know if they would have had like, anything that they could bite us with. Well anyway, I'm glad they don't exist!

Christian: Yeah.

Ellen: So that's all the, that's all the information I had on the Australian Emerald dragonfly.

Christian: Very good. Thank you.

Ellen: I have one thing before we move on.

Christian: Okay.

Ellen: It's a special treat. Do you remember last week when you wrote a poem about the botfly?

Christian: Yeah.

Ellen: So you did that, and it got a bunch of people riled up who rioted in the streets and demanded that I write a poem. I wrote a poem about the Australian emerald dragonfly.

Christian: Oh boy. Let's hear it.

Ellen: So here's my poem:

For their name to glorify,
Without a doubt they qualify.
Midges and mosquitos try
Escaping peril in the sky,
But though they flee and try to hide,
Their swarming tactics won’t divide
The focus of the steely-eyed
Australian emerald dragonfly.

Christian: Oh, that's so nice. I like it.

Ellen: That's my poem!

Christian: Well done honey.

Ellen: Thank you. What you got now, Christian? Step up your game.

Christian: Well, I'll put this out there now: I did not prepare a poem.

Ellen: Before we move on to Christian's animal, I would like to thank our patrons for this week: Briana Feinberg, Krystina Sanders, the Jungle Gym Queen, and Jacob Jones.

Christian: Oh, thanks y'all.

Ellen: Thank you guys.

Ellen: Now what you got Christian?

Christian: The species that I'm bringing to this episode is the leafy sea dragon.

Ellen: We did the sky dragon. This is the sea dragon.

Christian: Yes. Scientific name: Phycodurus eques. I'm assuming that's how that's pronounced, based on the word equestrian.

Ellen: You got it.

Christian: And this species was submitted by Dalton Weeks.

Ellen: Thanks Dalton!

Christian: And I'll be getting my information from Marinebio.org, Monterey- I typed in Monterey May Aquarium, but I know it to be MontereyBayAquarium.org, and nationalgeographic.com I have a fourth source, but I will mention that when I get to its content-specific piece.

Ellen: A secret surprise?

Christian: Yes.

Ellen: It's a surprise tool that'll help us later.

Christian: So first of all, these things have a nickname. They are called leafies.

Ellen: Oh! A leafy!

Christian: Yes.

Ellen: I love them.

Christian: And they get to be about 35 centimeters long, or 14 inches, thereabouts. And you can find these off the Southern coastline of Australia.

Ellen: This is a sub theme.

Christian: Yeah. So a-

Ellen: Primary theme theme, dragons, secondary theme, Australia.

Christian: So you mentioned Adelaide, I believe that is located in the Southern part of Australia, so it's even more themed. They belong to the taxonomic family Syngnathidae.

Ellen: Nailed it.

Christian: And the notable evolutionary relatives there are pipefish and sea horses.

Ellen: And the weedy sea dragon, right?

Christian: Yes. A lot of people will probably note they do look somewhat similar to sea horses, so that is their relation, but they are not the same thing. And to describe what these guys look like, so they are called the leafy sea dragon because they have appendages that look almost exactly like seaweed, and the color kind of ranges around the browns, yellows, olive-colored. That brings me to my first point of effectiveness, on which I'm giving an 8 out of 10.

Ellen: That's pretty good!

Christian: Yes. And the main thing there is camouflage.

Ellen: Yeah, that'll do it. That'll keep you alive.

Christian: Yep. That's its main thing. It's meant to blend in with the seaweed. Very well, I might add. So you'll see these things, the best way I can describe them is imagine a sea horse, but with leafy appendages.

Ellen: So the sea horse is like the day time, going to work office attire, and then at night when the seahorse goes out to the club, then you get the leafy sea dragon.

Christian: Sure.

Ellen: Leafy sea dragons are just drag sea horses. There, I said it.

Christian: Oh, that's what you're getting at. Okay, thank you. And real quick, what they eat: so they have these pipe-like snouts, and they use those to suck up small animals like plankton, mysids, and other small crustaceans. But that's, that's another trait that they share with seahorses is that little pipe snout.

Ellen: It's like a little straw that they're sucking stuff through?

Christian: Yep.

Ellen: Oh, okay. I guess they're not chewing things, then. Right?

Christian: I think they're just swallowing them whole.

Ellen: Aww, it's a little sea Roomba.

Christian: And I also wanted to mention that those little leafy appendages, they are not used for locomotion at all. They're just there for looks, for camouflage. And they also have little spots in them like, like the kind of spots you would actually see in seaweed. I just think that's really neat how closely they resemble it.

Ellen: That is cool.

Christian: Yeah.

Ellen: That's like when you talked about the Gaboon viper, and you mentioned how their head has a marking that is supposed to mimic the vein in a leaf.

Christian: Yeah.

Ellen: It's really cool when you look into animals that mimic foliage, it's insane how spot on they can get.

Christian: For sure. Also I should mention, the seadragon is a fish

Ellen: I guess... Okay. So logically I understand that, yes, that makes sense, but I guess I never thought of them or... Are seahorses fish? I don't know why this is surprising to me. It shouldn't be, right?

Christian: Well, it's peculiar because of their skeletal structure.

Ellen: Their shape. They're not shaped like fish.

Christian: Right. They're very unique.

Ellen: Yeah. It's really weird because now that I think of it, they're not shaped like fish, but they're not quite shaped like anything else.

Christian: Yeah. Yeah. So one thing that might help you better associate them with fish is how they do get around, or what their method of locomotion is. They have two small fins, one is along its back and the other one is further down its tail, and they undulate. Maybe like an eel.

Ellen: Okay. Okay. So it ripples sort of?

Christian: Yes. And these are small, these are small little fins. And they're almost transparent, so you have to look really close to see them. That's primarily what they use for locomotion.

Ellen: Wow. I never knew that they had a little fin I didn't know about!

Christian: Yep.

Ellen: They've got a secret fin that they didn't tell me they had.

Christian: Now because of this, they cannot move particularly quickly and they're very prone to being moved by strong currents.

Ellen: Oh no, bye!

Christian: Think I have a propensity to be washed up on the shore with storms.

Ellen: Oh my gosh.

Christian: Yes.

Ellen: I've never heard of that.

Christian: And my next one is their reproduction. So I think a lot of people have heard how with sea horses, the male carries the young.

Ellen: Best dad. Yep.

Christian: Yes. So one of- this is where one of the big differences are between seahorses and sea dragons. So seahorses, when the eggs are transferred to the male, they're in an internal pouch on the male, in their abdomen. Right?

Ellen: Sure. Yeah.

Christian: And then when they give birth, they just kind of come out of that pouch.

Ellen: Yeah.

Christian: With sea dragons, they do not have that pouch. They instead have what's called a brood patch.

Ellen: Brood patch?

Christian: Yes.

Ellen: Okay. I've heard of a brood pouch, but I haven't heard of a brood patch.

Christian: So it's an interesting thing. It's a little spot on the underside of the males' tails that, when when they're ready to reproduce, this area starts to look wrinkled. And so what happens is when they reproduce, the female will release the eggs and then those eggs will fit into little pockets on that brood pouch.

Ellen: Okay.

Christian: And then they get stuck there. The eggs are basically sitting on the outside of the male's body. And in this little brood pouch are blood vessels that supply oxygen to the eggs.

Ellen: Wow.

Christian: Yeah.

Ellen: Huh. That's crazy.

Christian: Yep.

Ellen: And does he like, carry them around until they hatch or?

Christian: Yes. So in this transfer from the female to male, this is also where the eggs are being fertilized. So the eggs are fertilized, they're attached to the underside of the male, and then four to six weeks later, they hatch.

Ellen: Do all of the members of this family have that sort of mechanic where the female transfers the eggs to the male and the male kind of takes it from there? Cause I know the seahorses do this, I did not know that the sea dragons did it as well.

Christian: Yeah. So I know the leafy sea dragon does this as well as the weedy sea dragon.

Ellen: Okay. That's really interesting cause I think I knew that they were related, but I didn't know that they also had a similar- but that's crazy that they have a similar behavior but it's different mechanically in the way that it works.

Christian: Right.

Ellen: That's really... Crazy, that it's similar but also so different.

Christian: And also I should mention when they do these eggs, the females transfer about 100 to 250 eggs.

Ellen: That's so many.

Christian: And they're pink!

Ellen: Ohh! I thought they couldn't get cuter!

Christian: Yeah. So four to six weeks later, the eggs hatch and the babies are on their own. For the first two or three days, they are supplied nutrients from yolk sacs that they got from the egg, similar to how other animals that are hatched. So eventually those nutrients run out and they have to start basically hunting for very, very small things that can get in their teeny-tiny pipe snoots.

Ellen: So like the, the adult sea dragon is swimming around with essentially like a smoothie straw, right? Big, big thick noodle that they're sucking stuff up through. And then here comes a little baby sea dragon with a little coffee stirrer straw. Just barely sucking up nothing. But you know what? That is a lot like the vampire squid that we talked about last week, how it just kind of sets the little eggs off and then it's like, well best of luck and it's got to live off of its egg yolk until it can survive.

Christian: Yeah. So that being said, not very many survive, but that's kind of the purpose of having that many eggs to try and beat the numbers game. Next point where I consider a deduction for their effectiveness is I'm going to say- I'm going to title it, "No Plan B."

Ellen: Okay.

Christian: Meaning if the camouflage fails, they don't really have anything else. They don't have a defense mechanism or a good way to escape outside of trying to hide again.

Ellen: They literally don't even have teeth.

Christian: No, nothing.

Ellen: Aw, poor babies.

Christian: We don't know of any particular species that like to eat these, but, I mean we know things can eat them.

Ellen: With how skinny and ornamental they are, they don't seem like they would be nutritionally dense. They don't seem like they would be a great meal.

Christian: Yeah. I think I read somewhere that even anemones are known to eat these.

Ellen: Really?

Christian: Yeah.

Ellen: How do they do that? How do they catch them?

Christian: I didn't look into it. I just saw them mentioned.

Ellen: Is it the case that like, not a lot of things eat the leafy sea dragons?

Christian: Well it's just, it's not known that like they're a preferred thing for any particular species.

Ellen: Okay. You know what is funny to me? The idea that like, even fish hate salads. Even fish look at a floating bundle of lettuce and they're like, "Mmm. I think not."

Christian: And then my final point is they're pretty fragile. So in addition to only having camouflage and then not being very mobile, they're pretty fragile in terms of could be damaged fairly easily. Divers are actually told not to try to handle them when you're in the same spaces as them.

Ellen: That kind of goes for any animal that you encounter while you're diving. Right? You're not supposed to touch 'em.

Christian: Yeah, but especially with these, because it could...

Ellen: They'll die.

Christian: It could hurt them. So yeah, that's my 8 out of 10 for effectiveness. That camouflage is really the biggest point there because once you see these things, you could see how even for a person you would have a hard time spotting these in the kelp environments and that kind of thing.

Ellen: Yeah. Very, very, very well specialized for that.

Christian: Yep. Ingenuity, I'm gonna do a 6 out of 10. I only had one point for ingenuity, and that's the fact that not only do they look like seaweed, but they also mimic the movement of the seaweed around them.

Ellen: Oh really?

Christian: Yes. So they try to match the swaying of the seaweed around them.

Ellen: Oh my gosh!

Christian: Yes.

Ellen: A third sub theme: motion camouflage.

Christian: Yup.

Ellen: Look at all of these common threads between the dragons!

Christian: And then final one, aesthetics. I'm giving a full 10 out of 10. I'm very impressed with the way they look.

Ellen: They're beautiful.

Christian: Yeah, they're very exotic and elegant and cute and they have very cool colors. I saw a little tidbit, I don't know how verifiable this is, but they seem to enjoy having their picture taken.

Ellen: I can vouch for this, because I have some really good pictures of the leafy sea dragons at the Florida Aquarium.

Christian: Yes!

Ellen: And they are like, posed perfectly. They're like, they're like, aligning perfectly with the background. So you get like a solid background. They have like, tilted and angled themselves in just the perfect way or it makes it very nicely framed picture. So I can personally confirm that, yes. This goes back to, this is a drag sea horse. This is a drag sea horse. It is a model and it is here for the look.

Christian: Excellent. So, time to get into some little miscellaneous information: conservation status is near threatened.

Ellen: Oh no!

Christian: So, a lot of that has to do with their popularity in the private pet trade.

Ellen: Bad.

Christian: So much so that their numbers were so badly affected in the 90s that Australia, uh, Southern Australia have put laws on the books to protect them. So they're very strict. You have to go through a lot of hoops to legally catch them out of the wild. And it's usually a solid, no.

Ellen: Probably not. Probably leave them alone.

Christian: And then, yeah, it's very regulated and usually they're only caught for educational and research purposes. The Monterey Bay Aquarium is one that has them as well as the Florida Aquarium, as you mentioned.

Ellen: Yeah, we love them.

Christian: Yeah. They've also been threatened by pollution, like fertilizer runoff and habitat loss, of course. So that's kind of a recurring theme.

Ellen: Yeah. That's something we get into with pretty much every ocean-dwelling animal.

Christian: Yeah. I want to talk a little bit more about what else distinguishes them from seahorses. So we've already talked about how their reproduction is a little bit different, and the other thing is sea horses can curl their tails and use them to grab onto things. Sea dragons cannot.

Ellen: Yeah, their whole body isn't really made for a whole lot of flexibility.

Christian: Right.

Ellen: Yeah. They're very highly ornamented, and that doesn't really give them a lot of wiggle room to be very flexible.

Christian: Yeah. They went in all in on the camouflage bit.

Ellen: They specked highly into stealth and little into dex. They min-maxed.

Christian: Yeah. And then last little final piece I want to talk about is, I got some information from a 2006 animated short that was created to educate school children and it was made on behalf of several South Australian organizations and it is titled "The Amazing Adventures of Gavin, a Leafy Sea Dragon.

Ellen: Gavin! I love you, Gavin!

Christian: It's this cute little cartoon, it's like 10, 15 minutes long. We follow Gavin, a leafy sea dragon on his journey along the Southern coast of Australia, and he meets other animals like a great white shark, a sea lion, nudibranchs.

Ellen: Oh, I love you Gavin! I love this. We'll have to drop a link to this video on our social media

Christian: Yes, you can find it on YouTube. The leafy sea dragon is the official marine emblem of the state of South Australia.

Ellen: Wow!

Christian: Yes.

Ellen: Excellent choice. So I have this really cool picture of one of the leafy sea dragons in the Florida Aquarium, and I was going through my pictures recently and I came across this picture again. I was like, yes. Awesome. And then I noticed something really weird that I hadn't noticed when I took the picture, that the sea dragon had these two little... Looked like plastic rings around its body. And I was like, "that's weird. What is that?" And so I did a little Googling and I found that these leafy sea dragons had some sort of injury that made them not float so good and they couldn't stay upright and they couldn't like swim correctly. They kept falling over to the sides. So the very, very nice people at the Florida Aquarium made them prosthetic floaties, made them little floaties that they put on the sea dragons to keep them upright and let them keep swimming around.

Christian: How cute.

Ellen: I didn't know that that was what it was, and I took a picture and it's so cute, and they're just good boys that just want to float around! And now they have floaties, Christian, they have floaties! It's so good!

Christian: How nice.

Ellen: Yeah. Top, top notch animal.

Christian: So that's the leafy sea dragon.

Ellen: Excellent. Nicely done.

Christian: Thank you.

Ellen: This was a couple of very good dragons.

Christian: Yes.

Ellen: That brings us to a close. Thank you so much to everybody who has spent this time with us. It means a lot to us that you checked us out, and thank you for recommending us to everybody that you know and annoying everybody with telling them to check out this really cool animal review podcast that you listen to. So thank you for doing that. If you want to hang out with us in the virtual space, you can connect with us on Twitter, Instagram, and Facebook. Just search the title of the show. You'll get there, I promise. We have a really cool group, so get in there. Oh, we did a giveaway, uh, that was going on over the course of the last week and the winner was Abigail Cornett!

Christian: Awesome!

Ellen: Thank you, Abigail. If you have an animal species you want to hear us review, you could submit those to us either on social media or at my email address, which is ellen@justthezooofus.com. A transcript of this episode and all of the rest of them is on www.justthezooofus.com, wrapping up, thank you, Louie Zong for the use of your song "Adventuring" off of your album Bee Sides.

Christian: Yes. Thank you so much.

Ellen: Maybe they should call it Dragon Sides.

Christian: Instead of bees?

Ellen: Yes.

Christian: Ah.

Ellen: I don't- It sounded good in my head. I don't know. Once it came out of my mouth, I knew it didn't. This kills the joke.

Christian: Thanks everyone!

Ellen: Bye!

26: Black Widow & Vampire Squid

Ellen: Hey everybody, this is Ellen Weatherford.

Christian: And this is Christian- (and then that's where it will interrupt with spooky music). That's right y'all. It's just the Boo of Us, Halloween edition.

Ellen: It's time to get spooky.

Christian: We here for it. Hope you are too. Otherwise... You're here anyway.

Ellen: We're not stuck in here with you. You're stuck in here with us.

Christian: Each animal we review on the show, we will rate out of 10 based on three spooky categories.

Ellen: You can't just say spooky in front of everything.

Christian: Okay, fine. Three categories: effectiveness, ingenuity and aesthetics. Bonus category: spookiness.

Ellen: It- Okay. I didn't build that into my notes, but it's okay. We'll do it on the fly.

Christian: Me neither, but we're doing it. We are not zoological experts. We do a lot of research and try our best to make sure we're presenting information from trustworthy resources. Who's first this week, hun?

Ellen: You.

Christian: Me? Okay.

Ellen: Yes.

Christian: What I bring this week to our...

Ellen: Chambers! To our dungeon!!!

Christian: Is the Southern black widow spider.

Ellen: Love her.

Christian: Scientific name: Latrodectus mactans. I chose this particular species just because it's near and dear to us, in our geographical area.

Ellen: In our garage.

Christian: Yeah. Many people are familiar with the term black widow spider, but that actually refers to about 30 some odd different species.

Ellen: Oh wow.

Christian: Yes. This species was submitted to us by What Are You podcast.

Ellen: Yay! That's with Megan and Dylan.

Christian: Hi Megan. Hi Dylan. And my information is coming from UF Entomology and Nematology website, entnemdept.ufl.edu.

Ellen: That was so many dots.

Christian: Lots of dots.

Ellen: They got a Morse code URL.

Christian: Also, Florida Department of Agriculture and Consumer Services found at FDACS.gov, and finally, Animal Diversity Web, found at animaldiversity.org.

Ellen: Represent.

Christian: Yup. So, let's get into it.

Ellen: Yeah. Introduce me to the spidder.

Christian: So for those that have not seen this spider, or maybe you haven't even seen a picture of this spider, a basic description is a shiny black spider with a distinctive red hourglass on the abdomen.

Ellen: It's very ominous and they're very pointy.

Christian: Yeah. Their legs are very, uh, spindly almost. Well, I dunno...

Ellen: Slender.

Christian: Sharp is how I would describe them. Although they're not actually sharp.

Ellen: They look like it though.

Christian: Yeah. So that's the basic description.

Ellen: This is like the iconic spooky spider.

Christian: Yeah, for sure. Let's talk about how big they are. So this is another animal where the size is different based on their sex. So for females they are 3.75 to 5 centimeters long, including their legs, and in imperial that is 1.5 to 2 inches. The bodies themselves are about 1.25 centimeters, or half an inch. Now with males, their bodies are only 0.6 centimeters long, or a quarter inch. So the females are a good double the size of the males.

Ellen: Jeez, she sure is. Big mama.

Christian: This particular species in the US is found in the Southeastern region. The range overlaps with the Northern black widow. Outdoors, this species can be found in wood and rock piles, rodent burrows and hollow tree stumps. Indoors, they can be found in places like outhouses, garages...

Ellen: Mmhmm.

Christian: Yeah, sheds and basements, usually low lying areas. Specifically, in our garage, near the ground, against the wall.

Ellen: Near our lawn mower.

Christian: Mmhmm. They belong to the taxonomic family- and I find this pretty funny about how this is pronounced, I think- Theridiidae.

Ellen: Oh my gosh. It's like, okay, so when I talked about the roly poly, the family name was Armadillidiidae. So this is very similar to that.

Christian: Yeah. They're also known as the tangle web spiders, and it includes over 3000 different species.

Ellen: Woof.

Christian: Let's jump into our first category: effectiveness. These are physical attributes. How good are they at what they do? For the Southern black widow, I'm giving a 7 out of 10. So first up, venom. It contains the neurotoxin alpha latrotoxin. It is said to be 15 times more toxic than a rattlesnake's venom.

Ellen: Whoa.

Christian: Yes. In humans, the symptoms of a bite starts one to three hours after the bite, and include: intense pain, rigid abdominal muscles, muscle cramping, malaise- which, this is a new word, I didn't know this word before, it means general discomfort whose source is hard to identify...

Ellen: It comes from the French word.

Christian: Oh yeah? What's the French word?

Ellen: It means, like, sickness.

Christian: Oh, okay. Sweating, nausea, vomiting and hypertension. And for those that aren't familiar, hypertension means an increase in blood pressure. Left untreated, those symptoms last three to five days. But, if you were to go to a hospital for this and you were having a severe enough reaction, calcium gluconate and/or antivenom may relieve or counteract those symptoms within 24 hours.

Ellen: Oh, okay. So this is very treatable, it sounds like.

Christian: Yes. My next point, human fatalities are very rare. One study says that between 2000 and 2006, a total of 23,409 bites from black widow species were reported in 47 States in the United States. So of all those bites, none were fatalities.

Ellen: Wow!

Christian: None.

Ellen: Okay, so they're maybe not as deadly as they're painted out to be. For humans, at least.

Christian: Well, especially not nowadays. So, first of all, the title of that study was "A US Perspective of Symptomatic Latrodectus [species pluralis] (meaning the Latrodectus, all of it species, so that's all the black widows) Envenomation and Treatment: A National Poison Data System Review," the author of that is Andrew A. Monte, MD, Becki Bucher-Bartelson, PhD, and Kennon J Heard, MD. That was published in 2011, and they got their data from the National Poison Data System.

Ellen: Good robust information.

Christian: Yes. So from a medical perspective, it's mostly small children, those with other immunity problems going on, that kind of thing that are most at risk of having a fatal reaction to to this bite.

Ellen: That makes sense.

Christian: Yep.

Ellen: And also they are kind of a metropolitan animal, right? Like they're okay with living in like, populated areas.

Christian: Yeah.

Ellen: So even if they do bite somebody, it's likely that you're not going to be like, a hundred miles away from the nearest hospital or something. Right? Like if you do develop symptoms, treatment is accessible.

Christian: Yup. And it seems like using antivenom is a pretty rare thing that is needed. It's usually only done when there's a very severe reaction.

Ellen: Do they use this venom as self-defense? Do they use it to kill their prey? Like, what is it- what is the venom for?

Christian: It's used to kill their prey.

Ellen: Oh, okay.

Christian: Yes. And then I'll talk about more in the ingenuity part as to why it becomes used on things like humans. So, the next thing on my effectiveness score is on the silk. I just think spider silk in general is very interesting.

Ellen: I'm just now realizing this is the first spider we've talked about.

Christian: Yep. So lots of spiders have silk, what they make their webs out of. I just think that's an interesting characteristic of spiders in general. You know, they use it to catch prey, to suspend egg sacks, that sort of thing. And speaking of egg sacks, my final thing for effectiveness is they have so many babies. Around 220 eggs in a single egg sack.

Ellen: That's so many.

Christian: It's a lot.

Ellen: That's a lot of babies. So are these like the type of spiders that carry their babies on their backs?

Christian: No.

Ellen: Okay, good. Thank God.

Christian: So they create an egg sack, put their eggs in there, and then they'll suspend it in their web usually.

Ellen: Okay.

Christian: I'm betting we might see one of those if we go into our garage.

Ellen: It's probably out there right now, yeah.

Christian: So yeah, that's what it does there. I mean obviously, it's one of those have as many babies as you can cause it's not very likely many of them will survive.

Ellen: I know, they're just little spiders.

Christian: And part of that is because of cannibalism, but...

Ellen: Oh, all right. We're back in praying mantis territory.

Christian: I think this is a common thing amongst bugs, insects and arachnids.

Ellen: Is this another femme fatale situation where the females eat the males after they mate?.

Christian: So that has to do with its namesake. I'm going to save that for the end.

Ellen: Okay.

Christian: That's my 7 out of 10 for effectiveness. I'm moving on to ingenuity. So this is where they do smart things, maybe hunting methods or tool use, that sort of thing. Being a spider, I'm going to give it a 4 out of 10 for ingenuity.

Ellen: Yeah...

Christian: This species of black widow, they make their webs without any kind of pattern. So a lot of the times when you think of a spiderweb, you think of kind of like a concentric circle type thing.

Ellen: Yeah. It's like radiating out from a point.

Christian: Yes. So lots of spiders do that. Black widows do not.

Ellen: Oh, is this where they get the name tangle web? Is that where the family "tangle web" comes from?

Christian: Yeah. Yeah. So, if you were to look at it overall, it would almost look like a, almost like a funnel type of shape, but it doesn't have any kind of distinguishable pattern. However, studies show that specimens with limited food resources will build more effective webs than spiders with at abundant food supply.

Ellen: What does that mean?

Christian: That means they're like, "Aw man, I'm not getting enough food. I better make a better web."

Ellen: Oh, interesting.

Christian: Right?

Ellen: They're kind of optimizing. They're like, well- that's really funny to me because that means that like, when they have access to a lot of food, they're like, "this is fine. Just just throw some silk up there. It's not that big a deal."

Christian: I mean, don't fix what's not broke, right?

Ellen: They're like, "I don't have to put that much effort into this." They're like the underachiever spider.

Christian: Yeah, yeah. So, and then my next and final thing for ingenuity is they actually have a very timid nature.

Ellen: Really?

Christian: Yeah. They will usually run away when confronted with something. They usually only bite something the size of a person if they're trapped between it and something else. So that could mean being sat on, being like- the person is grabbing something and there is a spider there...

Ellen: That doesn't make me feel good, because of this one time...

Christian: Okay.

Ellen: I used to work at PetSmart. I worked there for like two years, and one time it was the end of my shift, I had been on like a 10 hour shift and an important part of the job that I did very frequently was scooping crickets out of the cricket bin. If you've ever been in like, a PetSmart or a similar pet store where they sell crickets, they have them in a huge bin that's usually full of like egg crates and stuff for the crickets to hide in and stuff. So all day long I'd been reaching in there and scooping up crickets and bagging them up for people, and this is not something that you do with gloves on. You just do it because it's just, if you had to be like putting on gloves every single time you did this, you'd be wasting a lot of time and it would get really annoying. So you don't do this with gloves on, you just reach right in and grab it. Well, it was the end of my shift, it was probably like 8:30 at night and I had been doing this all day long and this customer saw me reaching in there and was like, "Whoa, hold on!" And I was like, "what?" And he was like, "that's a black widow, right there in the bin." And I looked and sure enough, it had the red hourglass on its back and it was sitting right on top of the crickets and I had been reaching in that bin all day long.

Christian: Wow!

Ellen: Yeah. And so he was like, "there's a black widow in there." And I freaked out and I, and like I didn't know what to do, so I went and got the manager. I think the manager just like got the spider out and sent it away. But I just felt so like, panicked that I had been reaching in there all day long with bare hands, inches away from a black widow.

Christian: Yeah. I mean, that was probably a big buffet for that spider.

Ellen: Yeah. So apparently that's actually really common. It's really common for spiders to get stuck in shipments of crickets, but the black widow just happened to be the one that was in there.

Christian: Wow.

Ellen: It freaked me out so bad. Happy Halloween!

Christian: So, one of the reasons that spider bites by the black widow have decreased over the decades is with the invention of indoor plumbing. I say this because one of the popular places for people to get bit by a black widow was in outhouses.

Ellen: ...Oh no!

Christian: Yes.

Ellen: Oh, gross.

Christian: Because they would hang out around the seat part of it...

Ellen: [gasp]

Christian: Yeah... Yeah.

Ellen: That is the worst scary story. This is our campfire scary story. I'm terrified right now.

Christian: But maybe check under your indoor toilet too.

Ellen: Stop it! You're the worst!

Christian: So moving onto aesthetics, how pretty is it? Or you know, aesthetically pleasing.

Ellen: Yes.

Christian: I'm giving a 9 out of 10.

Ellen: It's a beautiful spider.

Christian: Yes. So first of all, the glossy black look.

Ellen: Excellent.

Christian: Yeah, it's pretty interesting. It's kinda almost alien-like, to me. Interesting little thing to go back to how they differ between the sexes, so males actually lack the hourglass but may still have small red dots on the top or bottom of their abdomen.

Ellen: Are the males venomous as well?

Christian: Yes.

Ellen: Oh, that's not great. I don't like that you can't tell that they're black widows as easily, but they will still mess you up.

Christian: What I do is I just assume all spiders are potentially harmful

Ellen: Which is not to say- don't just kill every spider you see. Just like, scoop it up into a cup and put it outside, but also don't touch it.

Christian: Don't like, cuddle it with your face or anything. Um, spiderlings, which is what they call a little- the little spider...

Ellen: I never knew that! A spiderling!

Christian: The spiderlings are initially white, without the hourglass or spots. They progressively gain coloration and patterns with every molt.

Ellen: All right, thanks for the new gamer tag. Spiderling. I like that. That's so adorable.

Christian: Yeah, so 9 out of 10 aesthetics.

Ellen: Very good.

Christian: Spooky rating: uhhhh, probably 10 on 10. Funny story that I'm just now remembering, back when I was working on my bachelor's for computer science, I had this one class where we were learning how to program things for mobile devices. There was this one unit where I think it was an iPhone application, we were just learning how to do some things and it involved having like, a character you could drag with your finger and then when it runs into a different character or something happens. So what I did, I made that first character a big black widow spider, and then the second one, like a bird or something, and then when you drag the black widow spider to the bird, the bird disappears.

Ellen: What!

Christian: I don't know why I chose those things.

Ellen: That doesn't make a lot of sense.

Christian: It doesn't, but I learned... Something, I think.

Ellen: was the implication in your mind that the spider bit the bird and the bird died of the venom?

Christian: Well, also the scale was such that the spider was bigger than the bird.

Ellen: Here's my thought for our next D&D session: giant black widow spider. End of prompt.

Christian: Okay. So yeah, spook, 10 out of 10. Miscellaneous info about the black widow. So, their conservation status is no special status.

Ellen: Sure.

Christian: Makes sense. I don't think they're in any kind of trouble. Their namesake came from the belief that females kill and eat males after mating.

Ellen: Is this an accurate belief?

Christian: Not entirely. So that particular behavior was mostly observed in lab conditions with crowded enclosures. So it's thought that that act had more to do with the males not being able to get away than the desire of the black widow female to eat the males.

Ellen: Oh. So it was just kind of an opportunity thing. She just kind of saw the chance and she took it. You go, girl,

Christian: So it's thought in the wild, you know, the male would be able to get away. So that's the Southern black widow spider.

Ellen: Awesome. What a good spider. I have a new appreciation for our little roomy. For our little roommate in the garage.

Christian: Also side note, you know, they're beneficial because of all the bugs they eat.

Ellen: That is so true, and the reason why we have decided to make peace with the black widow that lives in our garage.

Christian: Yeah!

Ellen: So we came home and gosh, when was it that we saw that spider? We had like, I think we had just come home from our trip to Atlanta, and I was upstairs doing something and you were downstairs, I think you'd just come in from like, mowing the yard or something and you sent me a picture from the garage of this black widow spider and I could tell that it was inside of our garage and I was like, well, I didn't want to see that. I didn't want to know about that. But now I do, and I just have to be aware of that.

Christian: Yeah.

Ellen: But I mean, it seems like she stays in the garage and doesn't really bother anybody.

Christian: It's true. She hangs out by the garbage cans.

Ellen: Yeah. She's just kind of minding her own business and we leave her alone. She leaves us alone, and so that seems to be working out well for us so far. More than I can say for that wolf spider that got in our house. Do you remember that?

Christian: Yeah.

Ellen: This wolf spider got in and I saw it while I was- I was taking a shower!

Christian: Just like a movie.

Ellen: And I saw the spider up on the window inside the shower and I was like, "you know what, you kill bugs. I think I'm going to let you stay, but you're on thin ice, pal." And like we kind of had a little treaty. We had a peaceful truce where I just was like, okay, you do your thing, you keep the bugs in check, I'll let you live in my house. That's no big deal. And then like probably six hours later I was brushing my teeth, I think, in the bathroom and then I felt something that felt like a piece of hair on my arm because I shed a lot, and I went to go brush it off and it was that exact spider on my arm and I was like, you have betrayed me. You have betrayed my trust. How dare you. And then I had to come get you to help me put him outside.

Christian: Yeah.

Ellen: Black widow spider? She's okay. She can hang out. She can hang. We're okay with her.

Christian: As long as she stays there.

Ellen: She stays in the garage, and that's kind of her house. The garage belongs to her now. Um, before we move on to my segment, real quick shout out to our Patreon. We have some cool stuff on there, feed of the show with no ads. Cool stuff. Go check it out if you want to help us grow, for this week, thank you to our patrons, Briana Feinberg, Krystina Sanders, and the Jungle Gym Queen. Thanks y'all.

Christian: Thank you!

Christian: So Ellen, what do you have for us this spooky evening? (It's like 11 in the morning.)

Ellen: Well for this week, I have a very festively named friend. This is the vampire squid.

Christian: Ooooh!

Ellen: [poorly imitates sound of thunder] That's thunder crashing in the background, and imagine that there's a storm and lightning and stuff. Now, the vampire squid, scientific name Vampyroteuthis infernalis. This species was submitted by our buddies over at Spooky Spouses, which is a very delightful and perfect for the season little podcast done by Jordan and Lindsey Reed, it's really great, go check them out. They requested the vampire squid.

Christian: Thanks y'all.

Ellen: And also the jungle gym queen who is our buddy.

Christian: Thank you, thank you.

Ellen: Yes. Thank you to all of you who suggested this awesome animal. I'm getting all of my information on this animal from the Monterey Bay Aquarium Research Institute.

Christian: Ooh!

Ellen: Yes. They have kind of been the champions of vampire squid research. They have done like pretty much all of the research on this animal. They have done remote-operated vehicle dives, like where they've sent basically little like exploring robots into the ocean down into where the vampire squid lives. They had over 24 hours of footage from over 200 vampire squid encounters.

Christian: Wow!

Ellen: Yeah. Which is really something considering where they live. So to introduce you to the vampire squid, this is actually not a very big squid. Its total size of the whole body is about a foot long, or 30 centimeters. It's about the size and also the shape of a football. It's not that big. Also, males are smaller than the females.

Christian: Okay.

Ellen: Yeah. Just like the black widow.

Christian: A theme.

Ellen: So if you've never seen this squid, please look it up. It's so... Delightful. It looks like a squid with a sort of conical, tapered mantle at one end. The mantle being the part of the squid where all of the internal organs are. So if you're thinking of a squid in two parts, there's the arms on one end and the mantle on the other.

Christian: Yeah.

Ellen: So the arms are coming out of the mantle. So it has a conical tapered mantle at one end and then eight arms sticking out of the bottom. But the arms are webbed.

Christian: Yeah...

Ellen: So there's webbing in between the arms, which is not the way most other squids look. This gives it a look that is similar to a cloak or a bat's wing, which is where they get the name vampire from.

Christian: Gotcha.

Ellen: I feel like the webbing around the body makes it kind of look like it's wearing a skirt. That's what I think. Cause it's all the way around. Right? It's not just like, partial.

Christian: Sure, sure.

Ellen: So I think it looks like a skirt. It also has huge round eyes and two flappy fins above its eyes that look kinda like big giant Dumbo ears.

Christian: Aww!

Ellen: Yeah. You will find these all over the world in deep water between 300 and 4000 feet.

Christian: That's quite the range.

Ellen: Yeah. But typically the deeper the better. That is also between 90 and 1200 meters. You'll usually find them very, very deep though. Their taxonomic order is called Vampyromorphida. The vampire squid is not actually a squid. I'm sorry.

Christian: Whaaaat?

Ellen: It's not a squid. It is a cephalopod...

Christian: Okay...

Ellen: But it is not technically a squid. This species, the vampire squid is the only surviving member of not just its genus, not just its family, but its order.

Christian: Wow.

Ellen: The only one. Squids and cuttlefish are also cephalopods.

Christian: Okay.

Ellen: This species first appeared around 300 million years ago, and it has changed very little since then.

Christian: I guess, again with that, if it's not broke.

Ellen: Yeah. So this is why you'll see a lot of people refer to them as a living fossil.

Christian: Okay.

Ellen: Uh, for effectiveness, I'm giving the vampire squid a full 10 out of 10.

Christian: Wow!

Ellen: Yes. So I want you to think back to our episode on the Arabian camel. For the Arabian camel, I also gave them a 10 out of 10 for the adaptations that they had that allowed it to survive in extremely hostile environments. This is that. That was my reasoning for this full 10 out of 10. The vampire squid is extremely well suited to live in a very uninviting part of the world. So to explain that, first I'm going to explain how and what it eats.

Christian: Okay.

Ellen: So the vampire squid looks like a predator, and in fact the other squids and octopuses and stuff like that, they are predators. But the vampire squid is a detritovore. The way that they eat is they drift passively through the water. They kind of flutter their little fins a little bit, but for the most part they're just drifting. They're not really swimming actively. So they passively drift through the open water with their arms spread out like a net and they drag behind them a very, very long, very, very thin curly filament. So it looks like a giant piece of string trailing out behind them. They just kind of let it trail behind them as they swim around. Now this filament is covered in these tiny little microscopic hairs, and it also has sensory nerves in it. So the hairs gather these little bits of what's called "marine snow." Marine snow is just bits of debris floating through the water that consist of waste and remains of other sea life. So they're not actually eating animals, they're eating the remains and waste of other animals.

Christian: Huh.

Ellen: So they're basically just the little trash collectors of the ocean. Yeah, so once the filament has gathered enough little tasty snacks, the vampire squid closes up its arms and reels in the filament and pulls it back in and it pulls it between the arms and the arms scrape off the little yummy bits that it's collected on the filament. And then once it's scraped them all off of the filament, it deposits them into its mouth.

Christian: Wow.

Ellen: So on the inside of those arms, so from the outside it looks kind of like an umbrella, but on the inside all eight arms are lined with what looked like spikes. Pointy spikes.

Christian: Right.

Ellen: And they look very menacing. They look like very sharp teeth, but those are actually soft and fleshy structures that are called cirri. I think that they're very similar in structure and texture to the spiky silicone jewelry that was very popular in the late nineties and early aughts.

Christian: Okay...

Ellen: Do you know what I'm talking about?

Christian: I think so?

Ellen: It was like, every like preteen girl had these little earrings that was like a ball with these soft silicone spikes on it. Do you remember this?

Christian: I think so.

Ellen: This is what it makes me think of when I see their little cirri on the insides of their arms. It's very much like that. So the cirri are actually what the vampire squid uses to pull the food into its mouth. So they actually have two filaments.

Christian: Okay.

Ellen: And they have one extended at a time, and there's a pouch on the inside of the arms that stores the filament.

Christian: Huh.

Ellen: Yeah. So the cirri pull the food inside the mouth.

Christian: Okay.

Ellen: Now all of this, the diet of the vampire squid, was only known after observations in the wild by the Monterey Bay Aquarium Research Institute in 2012.

Christian: Wow.

Ellen: Before 2012, everybody thought that they just ate like, little shrimp and stuff like every other squid. Not so. It wasn't until just a few years ago that they found out what they actually eat.

Christian: Hmm. Crazy.

Ellen: Yeah. I know! This goes back to that thing that we talked about how we know more about the moon than about the deep sea.

Christian: Yeah.

Ellen: We're like, still learning about stuff that- animals that we've known about for like, a hundred years, and we just had no idea of what they ate.

Christian: Huh.

Ellen: Yeah. I thought that was really cool. So to tie that back into their effectiveness score, that very passive lifestyle of just drifting slowly through the water, that requires very little energy output. This is due to the fact that their bodies are actually neutrally buoyant like we talked about with the blobfish.

Christian: Yeah!

Ellen: So they don't have to spend any energy to drift through the water like that. They're just chilling, like letting the food come to them. They have this really, really slow metabolism and that combined with a very large gill surface area, and also a specialized type of blood. They have this specialized protein in their blood called hemocyanin. Hemocyanin is kind of analogous to hemoglobin that we have in our blood, except hemocyanin is based on copper instead of iron and it is blue instead of red. All you really need to know for this purpose is that it binds to oxygen much better at lower temperatures than hemoglobin, I won't go any further into the chemistry of all this because it's very complicated and confusing. Basically what you need to know is that they have this blue blood that makes them really, really good at passing oxygen through their body in low temperatures. So all of these adaptations allow them to survive in a part of the ocean called the oxygen minimal layer, and this is a part of the ocean that is so deep that there is as little as 5% or less oxygen saturation in the water. Little to no light, and there's also very, very, very little oxygen and they can live there just fine because they have all of these crazy adaptations that let them live on basically nothing.

Christian: That's awesome.

Ellen: It's so crazy isn't it? This part of the ocean is so cold and so low in oxygen that very few other animals are able to survive there, especially not anything that would be big enough to eat the vampire squid.

Christian: Ah.

Ellen: So like the things that do live down there are so tiny, right? They're like little microscopic like plankton and stuff. Nothing that lives there is going to be able to eat- not nothing, but like, so little that lives there is going to actually be able to eat the vampire squid, so they don't actually have to worry about predators at those depths.

Christian: Wow.

Ellen: So this was what I talked about with the camel. Right? They don't have to defend themselves because nothing's hunting them where they live. They just live where nothing else can survive, and they don't have to worry about fighting predators or anything.

Christian: Solid strat.

Ellen: Yes. It's very good. That being said, there's also very little prey found at these depths, like you know, yeah there's no predators but there is no prey either. But that's okay because they don't need prey! They eat detritus, they eat debris that falls from, you know, up the water column. Like, stuff from up above them falls down to where they are and it's okay. They don't need prey. They just swim around down at the bottom of the ocean and eat what falls down there. And they don't have to worry about anything.

Christian: Yeah.

Ellen: Yeah. I thought that was really cool. Now that's not to say that they don't have any defense mechanisms, because they do. They can defend themselves. They can. One of the standard like, defense strategies of other cephalopods like squids and octopus and stuff like that is two things: they will like, rapidly change their colors either to camouflage themselves or to start all the enemy, or they will shoot out an ink blob. You know, like an ink cloud to obscure themselves and then they'll get away. Now since this is a deep sea environment with little to no light, so you can't see anything, the vampire squid kind of skipped those things because they're not going to help them at all.

Christian: Sure.

Ellen: Like if you're in the bottom of the ocean where there's no light changing, your color isn't going to help because nobody can see you anyway, and shooting out a black cloud isn't gonna help cause everything's black. Like that's not going to obscure you at all. It's not going to help. So, what the vampire squid has instead is bioluminescence.

Christian: Really!

Ellen: Yes, they have some firework... They have some fireworks at their disposal instead. So the vampire squid's arms and mantle are equipped with light-producing organs, especially in the tips of the arms. And these organs allow the vampire squid to glow, as well as fire off clouds of glowing particles.

Christian: Woah!

Ellen: Yes. From the tips of its arms where it will actually like expel bioluminescence into the air and make this kind of fireworks display.

Christian: That's crazy.

Ellen: It is! It's very, very cool. The last thing I gave it for effectiveness was the fact that they have these really, really big round eyes that allow it to absorb as much light as possible down in the deep sea. This is like a common thing for deep sea creatures. I saw some sources say that that in proportion to the rest of its body, the vampire squid has the largest eyes in the animal kingdom, but then I saw some other sources say that there are like some tiny microscopic creatures whose eyes make up like a third of their body. And this is clearly not that. So, I don't know if it's like the largest in the animal kingdom, but they're definitely up there.

Christian: Okay.

Ellen: Very, very big eyes considering the size of their body. So that's my 10 out of 10 for effectiveness. This is like a hyper specialized animal.

Christian: Sure.

Ellen: So for ingenuity, I'm giving it a 6 out of 10. Okay.... It's okay. So, going back to its sort of escape strategy of using bioluminescence, they have this other thing that they do when they're threatened that they're known for. So they pull their arms up over the top of their head and they flip their body inside out. So they're exposing those spiky cirri outward. And this is called the pineapple posture, cause they look like a pineapple floating through the water.

Christian: I like that.

Ellen: It can look very scary! Like, it protects their mantle because they're shielding it with their web, but also it looks spooky.

Christian: Sure.

Ellen: It looks very, very scary. So it can look very intimidating and it can cause some predators to be like, "Oh my God, what is that?" And then they leave it alone. They will pineapple posture, it looks very scary and intimidating, but what they will also do when they're intimidated is they can flash their arms, they can do like pulsing displays of light, and then they shoot out their glowing cloud and then they use jet propulsion to swim away very quickly.

Christian: Okay. So they do have the ability to swim quickly, then.

Ellen: They can swim very quickly in very small amounts.

Christian: Right.

Ellen: In very small bursts. They can shoot a jet of water out of their mantle and it'll get them as far as they need to get. They can't do it for very long, but they can in very small bursts. It takes a lot of energy to do that, so they don't, they try to only do it when they really have to.

Christian: Sure.

Ellen: But they can. They have it. They have the capacity for it. So yeah, the vampire squid can control its luminosity, producing dimmer or brighter lights depending on the intensity of the threat. So they showed videos that the researchers took of like, them handling the squid in different amounts, and they found that the more the handled it, the more intensely they handled it, the brighter it would glow.

Christian: Ah.

Ellen: So it can actually control the intensity of its light. This actually is a major plot point of an episode of the Octonauts.

Christian: Really?

Ellen: For parents or, I suppose, just cartoon appreciators out there, there is a delightful cartoon on Netflix. I'm sure you can find it elsewhere, but we watch it on Netflix. It's called the Octonauts, and it's about this little crew of animals that just explore the ocean and help animals in the ocean- not just the ocean, but they help aquatic animals, like they rescue them and solve problems for them and stuff. And in one episode they find a vampire squid, and the vampire squid I guess like... Is injured and they have to help it, but then when they come up to it it gets scared and it like shoots off its glowing cloud and swims away. So, Octonauts is a very good show. You can learn a lot about like, aquatic life from that show. But as just like the quickest aside I can possibly make: a mistake in this episode has been listed on the IMDB page stating, "in the first few shots of Peso," which is I think the penguin, I think Peso's the penguin on the show, "he is in his deep sea suit, but in one shot he doesn't have his deep sea suit on. For the rest of the episode he is wearing his deep suit." And I saw that because I was looking up this episode on IMDB and I saw that this mistake was listed on there and it just... I was so filled with the light that there's somebody out there calling out the Octonauts on their continuity errors. It was like, first of all, who cares that much? First of all, who noticed it, and second of all, who felt so strongly about it that they had to take to the IMDB page of Octonauts and like publicly call out this episode for their inattention to detail? I don't know. I just really thought that was funny.

Christian: That's funny.

Ellen: So I took off some deductions for their ingenuity. The first deduction I took off was that since they are, like detritivores and they're literally just drifting through the water and the food is just coming to them, they're not hunting or foraging or anything, right? They're not like figuring things out.

Christian: Sure.

Ellen: They're literally just, it's kinda like they're just swimming through the water with their mouth wide open and hoping food lands in it. Right? That that doesn't take a lot of smarts. And I also took off a deduction because vampire squids don't guard their eggs or their young in any way. They just fire the eggs off into the open water and set them adrift.

Christian: Good luck! Byeee!

Ellen: That's literally what it is. Like, hope this works out for ya! See you later. And the young are just kind of left to fend for themselves. I guess where they live, there's not so many predators, so I guess that's okay, I guess? But still.

Christian: Yeah... I mean, unless maybe they are able to float to a different level of the ocean?

Ellen: They're not, they just float. They just drift.

Christian: What if other vampire squids accidentally eat them?

Ellen: Yeah. So they're bad parents. They're very, very bad parents. Only slightly better than the quokka, because they don't actively murder their children. So that's the end of my 6 out of 10 for ingenuity. Moving on to aesthetics for the vampire squid, I give them an 8 out of 10. I find them a little bit cartoonish. They have those big Dumbo ears like I mentioned earlier, those big round eyes, and what is essentially a giant hoop skirt. I think they're cute. Oh, and so the, the scientific name Vampyroteuthis infernalis literally translates to "vampire squid from hell," and I feel like that's completely unwarranted. Like I get that, like when they're turned inside out and they have all the spikes, if you think those are like spiky teeth, then yeah, that can look really terrifying. But I don't get it, at all. I don't, I don't get why they got such a menacing name.

Christian: I mean, I guess the first person that saw it might not have had a chance to actually feel the spikes.

Ellen: True. They may have just thought, "Oh my God, it's full of teeth." Like, get me out of here.

Christian: Did you happen to note when this was discovered?

Ellen: It was about a hundred years ago. I don't have an exact date, but it was about a hundred years ago.

Christian: Huh.

Ellen: So yeah, I guess if we're giving them spooky ratings, I'm actually going to give the vampire squid like a 3 out of 10 spooky. It's not spooky at all!

Christian: Okay, but if I were in the deep, deep ocean, and I came across this thing in pineapple mode...

Ellen: If we're- okay, if we're comparing it to other deep sea creatures, 0 out of 10. This is like the least spooky thing you could encounter deep in the ocean.

Christian: Okay, fine.

Ellen: There's- okay. Soft boi. Very soft. They have like almost like a jellyfish-like texture to their body, right? So, soft boi, a gentle glow to them, big dumbo ears... They won't do anything! They're completely harmless. They don't even have teeth. Way up inside of their mantle, like in the middle of, like hidden by all their arms and stuff. They have a little beak, but it's like interior. They cannot do anything to you! Like if I was at the bottom of the ocean and I came across a vampire squid, it would be a real breath of fresh air. I would be delighted to see one.

Christian: But because you know what it does and is, I feel like if you didn't know what it was, you would probably safely assume... nah.

Ellen: Yeah, that's true. I guess if I had never seen one before and this was my complete like, flying blind and I saw one of these, it would probably be a little terrifying, but...

Christian: You would think, "that thing wants all of my blood."

Ellen: Hence the name vampire squid. Yeah, but knowing what I know about it, I give a... What did I say before? Did I say 3?

Ellen: You said 3, and then 0.

Ellen: I'll split the difference. I'll say like a 2 out of 10. It's a 2 out of 10 spooky. This is not spooky at all. So wrapping up with some miscellaneous information, their conservation status is not evaluated. Like other deep sea creatures, they are threatened by changes in ocean temperatures and also acidity and declining oxygen levels. So all of those things naturally affect everything in the ocean, including vampire squids, even though their population numbers haven't been observed well enough to have a good idea where they're at as a species. And my last note that I want to include is that the only vampire squid to have ever been displayed in captivity was at the Monterey Bay Aquarium in May of 2014. They had a vampire squid on exhibit.

Christian: What happened to it?

Ellen: Not good. So they had it in May of 2014, it went out on exhibit, they, you know, said publicly that it was a rotating exhibit and they also said in their press release like... Like all deep sea creatures, they're very fragile and it, they basically were like, "Hey, it's not going to be here for long. Come check it out while you can." And they had it on an exhibit briefly, it wasn't doing very well so they took it off exhibit, and then I saw another thing from them saying that they put it back out for display again in August of 2014 which was a few months later. But then that was, that was it. I couldn't find anything else about it. I dug in to see if I could find anything about like, any updates on what happened to it, but I'm assuming it just died.

Christian: And now it haunts Monterey Bay Aquarium...

Ellen: The ghost of the vampire squid!

Christian: Just kind of ghosting around like, "Hey! You gonna eat that trash?"

Ellen: DON'T TOUCH MY TRASH! That's kind of the way it goes for any sort of deep sea creature. I feel like deep sea creatures, especially since the part of the ocean where the vampire squid lives is so low in oxygen, it's gotta be really hard to maintain an accurate simulation of that environment. So it's probably just not very good for them to be in captivity at all.

Christian: Yeah.

Ellen: But I mean they've got a lot, they've done a lot of really cool research on them and that was just the only time that one has ever been displayed in captivity. I wish I had had the chance to see it while it was there. But this is, this goes back to like, the great white shark. How like nobody's ever been able to like maintain one in captivity. It's probably best we just leave them alone, really.

Christian: Yeah. And people have tried, but you know it doesn't last very long.

Ellen: Yeah. Should probably just leave them alone then. Right? Like, maybe we can just let them do their thing. So yeah, that's the vampire squid. My new not-so-spooky friend.

Christian: Well thank you. I still maintain, though, that if one that would run into one of these and didn't know what it was or does, would probably be thoroughly spooked. All right, listeners, we've got a trick-or-treat special for you.

Ellen: This is both a trick and a treat.

Christian: Yes. So recently in the comments on a post in the Facebook group...

Ellen: Plug it.

Christian: Just the Zoo of Us... Special Friends...

Ellen: Nope.

Ellen: And more...

Ellen: Nope.

Christian: Just the Zoo of Us: Official Friend Squad.

Ellen: Thank you.

Christian: So in those comments, I volunteered to write a poem about the botfly. Not only was this not asked for, it was stated it was not wanted, specifically. I did it anyway, and it seemed to be well-received. It goes like this:

Eggs on a mosquito,
A bite on the arm
Larvae so snug
Prepare for alarm
You have a new pet
It lies mostly still
Say hello to the bot fly
Your very own flesh drill.

Ellen: Happy Halloweeeeeeen! Well, happy Halloween everybody, and thank you so much for spending this time with us.

Christian: Yes, thank you.

Ellen: We love y'all, and thank you especially to people who have been recommending us to your friends and giving us reviews on all of the various podcast resources out there. We really appreciate that. That means a lot to us. It's very cool of you.

Christian: Yes. Thank you so much.

Ellen: Very punk rock. Thank you. You can connect with us on Facebook, Twitter, or Instagram by searching the title of the show. Hey! Do that right now because we're having a giveaway, like right now. If you're listening to this before Saturday, November 2nd of 2019, head over to our social media because we're giving away a Final Straw, which is a metal collapsible reusable straw, and it is in rainbow, and also 2 decomposition books, which are spiral bound notebooks that are made out of recycled material and they have really, really cool designs on the covers. One of them is a jaguar and the other one is the Florida Everglades. So we're giving those away right now, so go check out our social media if you have not done that already, they're very cool. If you have an animal species that you want to hear us review, you can submit those to us at ellen@justthezooofus.com, or just kind of scream them into the void. I'm sure we'll get them. A transcript of this episode and others will be found at justthezooofus.com, and last note before we fade into the abyss is thank you to Louie Zong for the use of his song "Adventuring" from his album, Bee Sides.

Christian: Yes. Thank you. Should we use a spooky song instead this time?

Ellen: Well, I've already credited it, so no. But you know what we can do is we can just make ghosts sounds as we fade into the background. Wooooo~

Christian: ~Give me your traaash~.

Ellen: Bye!

Christian: Bye y'all.

25: Capybara & Gaboon Viper

Ellen: Hey everybody, this is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast where we take your favorite animal every week and we rate and review them out of 10 in the categories of effectiveness, ingenuity, and aesthetics.

Christian: We are not zoological experts. Anything we say can and will be used against us in a court of law.

Ellen: We're not experts, but we do a lot of research to get ready for the show and we make sure that we're giving you information from super good and reliable sources.

Christian: Who's up first this week?

Ellen: Me. I am.

Christian: All right, so what do you got for us, Ellen?

Ellen: This is the capybara.

Christian: Yay!

Ellen: Capybara, scientific name Hydrochoerus hydrochaerus.

Christian: Woah.

Ellen: I know, it's one of those, it's a little bit repetitive in the species name. It has an "a," where in the genus name it has an "o." So this species has only been technically requested one time, and it was like a billion years ago, and it was by Morgan Maher. Thank you. Morgan.

Christian: Yes, thank you.

Ellen: I'm getting my information on this animal from the Jacksonville Zoo, the San Diego Zoo, National Geographic, and some other sources that I'll cite when they come up.

Christian: All right.

Ellen: So to introduce you to my friend, the capybara: This is the world's largest rodent and it's an absolute unit. This is a big boy. Their adult size is typically up to 2 feet, or 60 centimeters tall, and up to 140 pounds, or 64 kilograms.

Christian: Okay.

Ellen: Yeah. They're dense little dudes, right? They're only two feet tall, but 140 pounds. That's like...

Christian: A small person.

Ellen: It is. It's about the, it's about the weight of a person. They're chunky little dudes. They're heavy for the size that they are.

Christian: But they still swim, right?

Ellen: They do swim. Don't worry, I'll get there. So yeah, this is the largest rodent on earth, and you can kind of see in their face that they kind of have that rodent sort of face. They have the face that a lot of people compare it to a beaver. It's very rectangular. When you see them inside profile, it's almost a perfect rectangle. That nose is like a very blunt sort of, straight down nose, so you can see it in the face. This is a mammal with wirey brown fur, they have small round ears on the very top of their head. You can find these big boys in Central and South America in riverbanks and marshes. So they're semi-aquatic. They spend most of their time chilling out in the water, but they do have to come out on land.

Christian: I am surprised to hear they're in central America. I guess I purely thought of them as being like Amazon rainforest type thing.

Ellen: You can find them in southern parts of Central America.

Christian: Okay.

Ellen: Yeah. Basically in any sort of tropical rain forest area that has a lot of standing water.

Christian: Gotcha.

Ellen: They can kind of make themselves at home there. Their taxonomic family is called Cavidae. This is the cavy family. Do you know what a cavy is?

Christian: No.

Ellen: So a cavy is a type of rodent that includes guinea pigs, and other rodents known as cavies include maras. But the thing that we would be most familiar with from this family would be a guinea pig.

Christian: Okay.

Ellen: So you can kind of see that in their face and in their feet also. When you look at them, they have the same kind of feet that a Guinea pig have that has the four toes pointing forward in the front, and then three toes on the back.

Christian: What...?

Ellen: Yeah. If you've ever looked really close at it, Guinea pigs pause like their front feet have four toes. Their back feet have three toes.

Christian: Oh! Okay.

Ellen: What are you thinking of?

Christian: I misinterpreted what you said. I was imagining one foot, with four toes on the front and then three foot- three toes on the back.

Ellen: Oh, like they have seven toes.

Christian: I was like, "You're blowing my mind!"

Ellen: Seven toes per paw. You never noticed how guinea pigs have seven toes? That's absurd. Anyway, so I'm going to get into my ratings. So first category that we like to look at is effectiveness, and we define this as how good the animal is at doing the things that it's trying to do. I give the capybara an 8 out of 10. The capybara has some really interesting adaptations that make it really good at getting around in the water. So, first of all, like, I mentioned that the front feet have four toes, the back feet have three toes. But one difference between the capybara and the guinea pig is that they have webbed feet.

Christian: Oh, okay.

Ellen: So there's actually webbing in between their toes, and that helps them generate some movement in the water. Also, whereas when you look at a guinea pig's toes, they have those very, like almost needle-sharp claws, the capybara has claws, but they're much more round and blunt and thick.

Christian: Kinda like a dog's maybe?

Ellen: I mean, I wouldn't even say that, it's just- it's a much thicker, blunter claw and it seems like it's more for digging into the ground.

Christian: Got it.

Ellen: So it's more for pushing on like mud and pushing off on riverbanks and stuff. It's more for gaining traction on the bottom of the water.

Christian: Okay.

Ellen: So they need to navigate in the water really well cause that's where they spend most of their time and that's where they find most of the vegetation that they eat. So they eat a lot of grasses that grow in the water, you know...

Christian: Kind of like our manatee friends.

Ellen: Yeah. Well they, they eat things on the surface of the water. So they'll eat plants growing on the surface or plants growing along the riverbank or stuff like that.

Christian: Like maybe lily pad-type plants.

Ellen: Yeah, yeah, they like to eat stuff like that.

Christian: Okay.

Ellen: They can also hold their breath for up to five minutes at a time.

Christian: That's a lot.

Ellen: It is. They can really go for a lengthy dive. They can chill in the water for quite a while. It's a good long time. Now what's really interesting that I hadn't actively thought about, but once I heard it, it kind of affected the way that I now look at capybaras, is that their eyes, ears and nostrils are all located along the top of the head. Instead of the, like for example, the nostrils being lower on the head, they're up top.

Christian: Okay.

Ellen: So the reason for this is so that the capybara can still hear, see, and breathe with the rest of their body submerged in the water. So kind of like when you talked about the matamata, how they have that tube-shaped nose, so that they can still breathe without having anything visible above the water. This is kind of that same concept where they're minimizing the amount of their body that they have to have out of the water.

Christian: Yeah.

Ellen: So they can do all of this stuff while only having a very small amount of their head exposed out of the water.

Christian: The imagery you described also makes me think of hippos.

Ellen: Yup. Yup. Similar to that.

Christian: Okay.

Ellen: They're not related to hippos, but...

Christian: No, but that same kind of principle, like having all of those sensory things on one plane.

Ellen: Yeah. Yeah. It is similar to hippos in that way. So all of those things contribute to it being pretty effective in the water, and so that's good because kind of their only defense strategy is to hide in the water. So if they see a predator or something, then the herd will run away as fast as they can, and they will try to run into the water so that they can hide there. Now, I did have to deduct two points from their effectiveness because they don't have any other means of defending themselves, and hiding in the water isn't going to do anything against, for example, caimans, anacondas, and jaguars.

Christian: Yes.

Ellen: All three of those will not hesitate to just pick one of those capybara right out of the herd.

Christian: And plus, one of those is normally in the water anyway.

Ellen: Well, two of them, caimans and anacondas are usually in the water and jaguars, as we talked about in a recent episode, will not hesitate to just jump right in. So yeah, I kinda had to take an effectiveness point off because yeah, you can hide in the water all you want, but that's still where the predators are.

Christian: I think that also kind of speaks to how impressive the anaconda is to, you know, of course, snakes eat their food whole, and this is a big boy.

Ellen: While I was researching this, I did stumble across on the internet a video of an anaconda swallowing a capybara.

Christian: Yeah.

Ellen: Which is ridiculous. That's absolutely insane. Please stop it. Stop it. I don't like it.

Christian: So, prior to this episode, the main thing I knew about capybaras is that... Food for anacondas. That was the thing.

Ellen: I don't think that anacondas are like their primary predator. I think it's jaguars, but it's also birds of prey that will pick them off, like eagles and stuff like that.

Christian: When they're young, maybe?

Ellen: You ever seen a harpy eagle?

Christian: Oh wait, is that the same area?

Ellen: Yeah.

Christian: Is it?

Ellen: Yeah. They're in South America.

Christian: Okay.

Ellen: Yeah. It's crazy. Right?

Christian: Yeah. Poor capybara.

Ellen: Yeah, he's not doing great. So, yeah, the capybara doesn't really have any other sort of defense strategies, although in order to sort of make up for their vulnerability, like other rodents, they are prolific breeders. So they can have a litter of up to eight babies at a time.

Christian: That's the quantity over quality type thing, I guess.

Ellen: Yeah. That's kind of the rodent approach, right? It's like they have kind of come to terms with like, okay, most of us are gonna die. Most of us are gonna get eaten very quickly, so let's just make very many of us.

Christian: That one's going to be the ammunition baby... Quokka.

Ellen: Thanks.

Christian: Not that quokka is a rodent.

Ellen: Now that kind of paints a picture like the capybara's not a good mom, but she is. I'll talk about that in a second. But yeah, so that all is just to say that they are very well adapted to thriving in aquatic environments, they're pretty good at doing a good job of eating a bunch of grass and hiding in the water. But when it comes to fighting back against predators, no real options there.

Christian: Yeah, they're good at being in the water, but so is a lot of other things there.

Ellen: So are the things that eat them. So maybe in that respect, maybe actually taking to the water was not such a great idea.

Christian: Ah well.

Ellen: But so yeah, that's the 8 out of 10 I gave them for effectiveness. For ingenuity, and this surprised me, 9 out of 10.

Christian: Okay.

Ellen: Clever, clever little dude, which you might not think because of the sort of pace that they live their life. at. They are on their own time. They're on the capybara clock. Like, they're actually pretty clever. I feel like since they do have some real weaknesses, they are negating those weaknesses by finding strength in numbers. So capybara live together in herds of up to 40 individuals.

Christian: Wow.

Ellen: So large groups, they're very, very social. And they live together in these big groups. They're called herds, and the herd has a social hierarchy where it'll have a dominant male and then some subordinate males, and it also has the females and all of their babies. So some interesting sort of class structure in the capybara herd. Capybaras have a really complex vocal language.

Christian: Ooh!

Ellen: Yeah. I found this information in the study "Vocal Repertoire of Captive Capybara (Hydrochoerus hydrochaeris): Structure, Context and Function" by Kamila S. Barros and the Applied Ethology Laboratory at the State University of Santa Cruz. What this study basically showed was that capybaras have a really complex vocal language that is comprised of seven types of calls: whistle, cry, whine, squeal, bark, click and tooth chattering. And all of those calls mean different things.

Christian: Okay.

Ellen: So I'm not going to break every single one of those down. If you really want a deep dive into what all of these calls mean, read the study. It's so good. But, so for example, if one capybara sees a predator, they will bark to warn their herd that there's a predator nearby, and then the herd will run into the water. But another example is this clicking sound that they make. So when the herd is moving together, all of the individuals in the herd make this clicking noise at each other and it's to coordinate their movement. And the understanding in the study was that it's a mechanism that allows them to know each other's location when they're moving through thick vegetation. Cause keep in mind they're in like marshy, rain forest sort of lands. So they might not always have eye contact with each other, they might not always have line of sight, so they have to be able to communicate with each of the vocally so that they all get to the same place.

Christian: Cool.

Ellen: Yeah. There's all these other vocalizations that they have that mean all these different things that they communicate with each other in the herd, and what was really interesting to me is that the study even noted some variation in the structures of the different calls between different herds. So they have not only a language, but they have accents.

Christian: Nice.

Ellen: So like capybaras in different herds will maybe make sounds a little differently from others. Like maybe their bark will be a different pitch.

Christian: Yeah.

Ellen: Yeah. So it's just really cool that they have little accents from each other. Little dialects of capybara language. Another thing about herd structure is that capybara mothers will actually nurse all of the babies in the herd, not just their own.

Christian: Okay.

Ellen: So they're not picky. They'll just kind of nurse whatever baby they see. They'll just, they kind of stick up for each other. You know? They're very altruistic. They will take care of, you know, like a capybara mom is a mom to all capybaras.

Christian: That's nice.

Ellen: She's a very good mommy and she takes care of all of the babies, not just her own baby. The next thing that I want to talk about is their trainability. So I got this information from Hannah Louise Sinclaire, and Hannah Louise Sinclaire I have connected with on Instagram, and she has probably the coolest Instagram feed I've ever seen. So she works directly with not only capybaras but a lot of other interesting animals like bald ibis, tapirs, meerkats, all sorts of really cool stuff.

Christian: Neat.

Ellen: Yeah. So I reached out to her and I asked her if she could provide some of her experience, you know, working with capybaras and training them and providing enrichment for them and stuff. And she was so, so incredibly nice, she sent me so much awesome like, firsthand experience with capybaras.

Christian: That's awesome!

Ellen: So I really appreciated that she did that. So if you are on Instagram and you like capybaras, look up Hannah Louise Sinclaire cause that's where it's at. She told me that capybaras respond particularly well to tactile reinforcement... Chin scritches!

Christian: Yay!

Ellen: They love chin scritches. So she said they actually accept pets as rewards.

Christian: Aww...

Ellen: So she says their hair stands on end when you pet them, and that they will actively ask for pets. So they'll actually like, come up you and sort of prompt you to pet them. And she said that she's actually been able to train medical procedures like blood draws and injections just by using scritches as rewards.

Christian: That's awesome.

Ellen: Like, instead of like, a food reward. You know, like for other animals you might offer like a little a small food treat?

Christian: Sure.

Ellen: But for capybaras, they just use little scritches on the chin and that's, and they're happy about it.

Christian: How precious.

Ellen: And they just like that. Yes, it's very endearing. I really like it. She did say that training adult capybaras to follow targets- if you've ever seen, it could be something like a long stick with a ball on the end where they're supposed to like follow it. So doing target training for adult capybaras can be a little challenging at times because sometimes even though they understand the command and they know what they're supposed to do, they're very lazy and sometimes they just don't feel like it. So sometimes they can be a little bit stubborn. But Hannah says that they have definitely learned to recognize who she is, as well as her voice and the clicker that she uses to train them. She says that for the capybaras that she works with, they provide enrichment in the form of food hidden inside balls or placed up high out of reach, so that they have to work to get the food. So being rodents, naturally, they're still very skittish and even after learning to trust her over time, they still startle very easily.

Christian: Yeah...

Ellen: I thought that was all just really, really interesting. It sounds like capybaras are a real delight to work with.

Christian: Sounds like it.

Ellen: I've never gotten to actually like interact with a capybara before, but I hope that I do someday. So that is my 9 out of 10 for their ingenuity. I think they're pretty clever.

Christian: Sounds like it.

Ellen: They've kinda got life figured out, right? I think they're just all about it. This brings me to aesthetics for aesthetics, I'm giving them a 7 out of 10 for the fact that they do just kind of look pretty plain. They're just all a solid brown color. They have that wiry hair. They don't actually have the facial muscles to produce emotional expressions, so you just kind of get one flat expression where they kind of have their eyes sort of half closed. They have that very relaxed expression that reminds me of Saitama from One Punch Man.

Christian: Oh, really?

Ellen: It reminds me of that guy. Like when he's drawn in that very like simplistic style where his eyes are like half open. That's capybara town right there. Like that's what that makes me think of. Now for aesthetics, I gave them a 7 out of 10. For the capybara, I'm going to include a very special edition subcategory...

Christian: Uh oh!

Ellen: Of the chill factor, and I'm giving them a 10 out of 10.

Christian: Hot off the press!

Ellen: 10 out of 10 chill. They are indescribably chill. They're so chill that just looking at them, I feel like it just lowers your blood pressure. Like you look at a capybara and you're like, things are good. They are a very chill animal. I like if there was an Olympic event for chill, capybara would take home the gold every year.

Christian: I feel like I've seen lots of pictures and videos of them just kind of like, cuddling, laying around with each other.

Ellen: Yeah. And not just with each other, which is the weird thing. They're down to kick it with literally anybody. Like, as skittish as they can be, there is a Tumblr blog, animalssittingoncapybaras.tumblr.com...

Christian: Oh boy.

Ellen: And it's just a blog of photos of animals sitting on capybaras. My personal favorite is the goat. There are multiple pictures of capybaras with little goats standing on top of them, which is really adorable because goats will stand on top of anything. Like, we know this to be true. Goats want to be as high up as they possibly can get at all times.

Christian: Sure.

Ellen: And the capybaras is just like rolling with it, like he's just totally cool with it and this goes like standing on his head. It's really cute.

Christian: Well, it's good to hear that that exists, and also that tumblr is still kickin' it.

Ellen: It's an underdog story. Another cute thing, so we talked about this recently in our Facebook group and that yielded our friend Alix at the Pomegranates and Pitchforks podcast, who is a delightful presence in our Facebook group, made a couple of very charming illustrations of a capybara being a very good mom to all of the other animals, and like tucking in like a snake and a monkey and checking in- Did you not see this?

Christian: No.

Ellen: It was so cute! She's like, like it's like capybara mom, like checking in on like... A little porcupine baby and being like, just checking on you. Oh, I didn't say the hot baths! Okay. Another cute thing that they do is in Japan, in zoos where they have capybaras, they put them in hot springs and let them take hot baths, and it's the best thing I've ever seen. Look up videos of capybaras in Japanese hot baths. They have these hot baths and these hot springs and the capybaras will just line up single file and they very slowly and calmly step into the tub one after another and then like 10 of them get in a tub altogether and they're just all packed in so tightly, but they're having a really good bath, and it's really cute! And the bath has like a bunch of lemons in it also.

Christian: Okay.

Ellen: And it's very charming.

Christian: I'm imagining every one of them has a little washcloth on their block heads.

Ellen: There's one, I saw one video because I kind of went down a rabbit hole of watching capybaras taking hot baths, and in one video I saw there was one that was doing that thing where it was totally under all the water with just its nose and the top of its head sticking out of the water, and on top of its head was a leaf.

Christian: Oh!

Ellen: It's really cute. So, also if you want some really good ASMR, there are a lot of videos out there of capybara eating various foods. My favorite is the popsicle, but there's also some good ones of them eating watermelon if you're into ASMR, that's some good ones. They make very pleasant and satisfying sounds. If you're ever feeling upset, just think to yourself, what would a capybara do, and then you take a hot bath and you eat some leaves, and you make a bunch of clicking sounds.

Christian: And then get eaten.

Ellen: And then get eaten by a jaguar. So yeah, that's my 10 out of 10 chill factor, 7 out of 10 aesthetic factor for the capybara.

Christian: Very good.

Ellen: Yeah. So to wrap things up for the capybara, their conservation status is of least concern. They're doing fine. Uh, in some places where they live, they can be hunted for meat or pelts, but some captive farming efforts have sprung up to sort of offset that, where people that are consuming capybara are farming them, like breeding them and farming them, which is helping to not put so much pressure on people in that area to hunt them wild. So it's allowing wild populations to stabilize.

Christian: Sounds good.

Ellen: But they are still, of course, threatened by deforestation and habitat loss as are literally everything that lives anywhere.

Christian: Yep.

Ellen: Particularly so in the rainforest, if you live in the rainforest, there's always the looming threat of deforestation. But also a small invasive population of capybaras has been observed in Florida.

Christian: Really?

Ellen: Yep! It's unknown how many there are currently, but our habitat is pretty much perfect for them. Right?

Christian: Yeah.

Ellen: Like we got that whole tropical forest swamp land.... We have pretty much everything a capybara needs to like, Thrive.

Christian: We have two out of the three predators though...

Ellen: ...No we don't. We got gators. I think it gator would definitely eat a capybara.

Christian: Maybe a mountain lion might go for it?

Ellen: I don't think a mountain lion would go for it. I don't think.

Christian: I feel like it would.

Ellen: I don't think it would. We don't have anacondas though.

Christian: But we have invasive pythons.

Ellen: We have invasive pythons...

Christian: Maybe not as big.

Ellen: Yeah, definitely not that big. So I feel like an adult capybara would be like, safe here where we live. I've never seen one, and I couldn't get like a good specific location where these invasive wild capybaras are, but it did say North Florida.

Christian: What?

Ellen: Yeah, it said North Florida. I guess there was some sort of research facility that had some and they escaped and went wild.

Christian: The weird Jurassic Park sequel.

Ellen: Well, but I've never seen one. But I wonder if it would be easy to mistake one for nutria?

Christian: No, nutria are much smaller.

Ellen: Yeah, I know they're much smaller, but like I wonder if anybody would ever like... See one and be like, "Oh that's a nutria" or something.

Christian: I at least I wouldn't, but- well now, I won't be so shocked if I happen to see a capybara just walking across the street. I mean, I'll be surprised, but I'll be like, "Oh okay. Yeah, that makes sense."

Ellen: That tracks. That's fine.

Christian: Or if someone lost their pet or something, I don't know.

Ellen: Now some people do keep them as pets.

Christian: Oh yeah?

Ellen: It's legal in two states. One of them is Texas, I don't remember what the other one is, but in some states it's legal to have them with an exotic pet license. So the reasoning behind that is some people think since they're so docile and non-threatening that they could be good pets. But another thing about it is that they're so social that I feel like if you were going to have one and have it thrive and do very- and be healthy and happy, you would have to have like 10 of them at least.

Christian: Yikes.

Ellen: So it's like, I dunno. It's like, just because you can doesn't mean you should. Right?

Christian: Yeah.

Ellen: Just don't, don't do that. Don't keep them as pets. Don't keep them in your house. I'm just saying our bathtub's not that big. So that's the capybara.

Christian: Very good.

Ellen: I was- I felt like I went into this thinking this might be kind of a boring animal, because when we see them like at the zoo or something, they're usually just laying there. We've seen them get in the water and swim around a little bit, but they're almost always just kind of chilling, laying on the side, eyes closed, just vibing, basically like they're just keeping it tight. So I was a little bit worried that this would be a boring animal, but not so I felt like there were a lot more interesting than I thought they were going to be.

Christian: Very good.

Ellen: Yeah, that's the capybara.

Christian: I like them a lot.

Ellen: Me too. Before we do your animal, I just want to give a real quick shout out to our Patreon. We have some cool stuff on there, like a feed of the show with no ads and also I send out prints of photos that I've taken of cool animals. So, you know, go, go check us out at patreon.com/justthezooofus. And for this week I would like to thank our sponsors, Briana Feinberg, Krystina Sanders, and the Jungle Gym Queen. Thanks y'all.

Christian: Thank you.

Ellen: Alright baby. It's your turn.

Christian: Okay!

Ellen: Who are we talking about this week?

Christian: So this week I'm bringing to the... To the ball court...

Ellen: To the ball court...?

Christian: And deep in the paint, the Gaboon viper.

Ellen: Ooh!

Christian: Scientific name, get ready for it.

Ellen: Okay. I'm braced.

Christian: Bitis gabonica.

Ellen: Bitis?

Christian: Yes.

Ellen: It bite you.

Christian: Bit us.

Ellen: It bite. We call it Bitis. Hey, we need you to come up with a, we need to come up with a name for this genus of snakes that bites real good. Um, Bitis.

Christian: So yes, Gaboon viper. This species was submitted by Sarah Horne. Thank you Sarah.

Ellen: Thanks Sarah.

Christian: And I'm getting information for this little dude from the Smithsonian's National Zoo and Conservation Biology Institute website, which can be found at nationalzoo.si.edu, and also again, Animal Diversity Web from the University of Michigan Museum of Zoology, found at animaldiversity.org.

Ellen: We love y'all so much.

Christian: Good source. So, let's talk about some basic stats on the Gaboon viper. Obviously a snake. So, uh, let's talk about how big these things are. So first of all, it is the largest viper in Africa. They can weigh more than 45 pounds.

Ellen: What!

Christian: Or 20 kilograms.

Ellen: That's huge for a snake, right?

Christian: That's like, two of our dog.

Ellen: Could probably eat two of our dog.

Christian: And they reach lengths of more than 6 feet, or 1.8 meters.

Ellen: This is not a little guy at all. You lied.

Christian: Yeah, you're right. Bamboozled. Uh, they can reach nearly 6 inches, or 15 centimeters across at their widest point, so they are hefty.

Ellen: This is uh, thicc.

Christian: Yeah. So, if you ever see these, pictures of these or even at a zoo, you'll notice they are kind of on the thicker side.

Ellen: I have seen, we have one at our zoo. We have one at the Jacksonville Zoo and I have seen this friend, and this is a very plump fellow.

Christian: Very much so. You'll find these in rainforests and wet areas in Central, East, and West Africa. In the wild, at least. They are popular zoo animals.

Ellen: Sure, sure sure.

Christian: Mostly because they look neat.

Ellen: They do.

Christian: They belong to the taxonomic family Viperidae, and their relatives being other vipers of course.

Ellen: Sure.

Christian: So those being things like rattlesnakes, water moccasins from episode 5.

Ellen: There you go!

Christian: And copperheads.

Ellen: I feel like the water moccasin is also a little chunky.

Christian: Yeah, a little bit. I think that might be something just common though, with a lot of vipers.

Ellen: Wait, this is episode 25. We've done 50 species. Of those, two of them have been snakes, and both of them have been fat, and both of them were done by you. What's your thing with fat snakes?

Christian: So I'm starting to remember that as a kid growing up, reptiles were my favorite.

Ellen: That's true.

Christian: So that's all I've got to say about that. And the thing about vipers, there's kinda some subclasses there. So there are vipers that have pits, the heat sensing organs on there, the top of their lips. The Gaboon viper is not one of them.

Ellen: I don't know why I thought this, but I thought that the "pit" part of pit viper meant that they like... Nested in pits or something like that? I don't know why I thought- maybe I was thinking of like, the scene from Indiana Jones where there's a pit full of snakes and I'm like... I thought that they like lived in pits for some reason, and I thought those were pit vipers.

Christian: It's always snakes!

Ellen: That's the dumbest animal thing I thought.

Christian: So I'm gonna jump right into it. Effectiveness, I'm giving a 9 out of 10 for the Gaboon viper. So my first point is its camouflage. The camouflage is so the coloration of its scales and also the shape of its head and makes it so it blends in really, really well with leaf litter on the bottom of a forest floor. Its head is even shaped like a leaf.

Ellen: Oh, that makes sense! Cause I know what their head looks like and I hadn't, I hadn't made that connection.

Christian: It even has coloration that makes it look like it has a central vein going down the center of its head, that looks like what a leaf would have.

Ellen: Oh, that's what that is!

Christian: Yep.

Ellen: Wow. And they have some really interesting like, high-contrasting patterns too.

Christian: Yeah. Yeah.

Ellen: It's really cool.

Christian: Lots of browns and like, I guess white-adjacent kind of colors. Even some purple sometimes.

Ellen: Ooooh, so pretty.

Christian: Yeah. So camouflage, it's very well hidden in its natural habitat. Next point, of course, is its venom. So being part of the viper family, they're all venomous. And this one, a good bit.

Ellen: I feel like I've heard of them being ranked as like, some of the most venomous.

Christian: So here's the thing. Yes, it is venomous and you do not want to be bit by them. It has a very bad rap for its bites. There had been people that have died from it.

Ellen: Oh no.

Christian: But it's rare. I'll get into a little bit why that's rare, but let me just talk about the venom. So its venom contains neurotoxin and hematoxin, so it destroys blood cells and vessels. But here's the thing about its venom: pound for pound, it's not particularly toxic as compared to other snakes. But here's the thing, it doesn't have to be. It has some of the largest venom snack... Venom snacks.

Ellen: Venom snacks!

Christian: It has some of the largest venom sacs of any venomous snake. So what it lacks in toxicity, it makes up for in quantity.

Ellen: Oh, so it's just pumping you full of this stuff?

Christian: Yes.

Ellen: Oh, okay. Interesting.

Christian: So when you look at its head, you'll notice that, you know, the part of its head where the venom sacs are, are very bulbous. Right?

Ellen: It's got big old cheeks.

Christian: Yep. Yep. Those are death cheeks.

Ellen: It's kind of like how, you know, like chipmunks will store their food and their cheeks, but the Gaboon viper stores hatred and death in its cheeks.

Christian: Yep. And also, kind of the last point about effectiveness, it has the longest fangs of all venomous snakes that go up to 2 inches, or 5 centimeters.

Ellen: Wow. Some big toofers.

Christian: They're big. So they get deep, and they can pump a lot of venom in there.

Ellen: That's an interesting approach. They're like, "Hmm, instead of making really, really good poison, we'll just make a bunch of it."

Christian: Yeah. Basically. So I'm going to move on to ingenuity. I'm giving it a 7 out of 10 for ingenuity.

Ellen: That's not bad.

Christian: So Gaboon vipers are passive hunters, meaning they usually go somewhere that they know prey will frequent, and they just sit and wait until something walks along. It's still relying on its camouflage.

Ellen: It's like an ambush predator.

Christian: Yeah, yeah. And it's nocturnal. The next point I'm going to give is its placid nature.

Ellen: Placid?

Christian: Yes. It very rarely bites humans. If we're talking about the chill factor for snakes, it's pretty high up there.

Ellen: This was an unexpected common thread for this episode. I feel like a lot of times we end up finding some sort of like, hidden surprise theme. I didn't think the chill factor was going to be it.

Christian: They don't look chill at all.

Ellen: No, they don't. They don't look like it. They look very extra.

Christian: So most bites with humans happen when they get stepped on, because of their very good camouflage.

Ellen: No step on snek.

Christian: Yeah. They'll usually hiss before biting, but you know, if they get stepped on, they can't get away. They're going to bite. They're more likely to bite when they're hungry, so it could be a case of mistaken identity.

Ellen: Sure.

Christian: That's more so in captive settings. So when you're feeding Gaboon vipers, a lot of the cases you hear about of people being bitten by a Gaboon viper happen with captive snakes.

Ellen: I've never had a pet snake myself, but you have.

Christian: Yes.

Ellen: Did your snake ever bite you because it was hungry?

Christian: I have never- I was never bitten by my snake, but there's something from that experience that I will never ever forget. When I went to the pet shop with my mom, and this was in Rhode Island, to pick out a pet, and which I would ultimately pick a ball python, but I asked the person working there, "does it bite?" And what he said, I'll always remember, he says, "if it has a mouth, it can bite."

Ellen: Yes. Except... The anteater.

Christian: Yes. It just kind of, *thwpp* I don't know what you call that.

Ellen: The anteater and the tamandua will not bite you, BUT the point still stands.

Christian: Yeah. So even though these guys are normally very placid, I still do not recommend messing with them.

Ellen: Yeah, still don't, y'all.

Christian: One story I read about someone that was bitten by a Gaboon viper that they owned and ultimately died from was, you know, they weren't doing the proper handling methods. They weren't using like the snake... Stick, I dunno what you call it. Um, it has like a little grabby thing at the end of it.

Ellen: I know what you're talking about.

Christian: Tthis person was just bare-handed, you know, grabbing these things.

Ellen: Oh my God. I don't know how to explain to people not to do that.

Christian: Yeah, yeah.

Ellen: Like I don't know how to tell people, don't just kinda Leroy Jenkins your Gaboon viper.

Christian: So while these things can be very dangerous, the bites are very rare because of this nature, and also they're kind of reclusive. The kind of the rap they have is a little unwarranted. Just a little. Cause we're talking, you know, number of bodies, it's negligible, almost.

Ellen: I guess what you're going for is like, they're not as aggressive as you might think.

Christian: Yeah. They're not just like dealing death left and right. You know. Another thing that they do that I counted towards ingenuity is that a lot of venomous snakes, when they do a strike, they'll bite quickly, inject some venomum- Venomum.

Ellen: Venomum?

Christian: You take venom, and you mix it with cinnamon, and then you're basically dead.

Ellen: My favorite breakfast is a venomum roll.

Christian: Just like grandmanum used to make. Okay, okay, okay. So most venomous snakes, it's a very quick action. It's a bite, inject, release. Very quick. You can blink and miss it, basically.

Ellen: Sure.

Christian: These guys do not do that. They bite and they hold on. They don't let go.

Ellen: Oh! They're comin for ya.

Christian: So this goes back to that method of quantity of venom.

Ellen: Oh, that makes sense. They're probably just trying to pump as much venom as they can in there.

Christian: Yes.

Ellen: That's cool!

Christian: Now it also helps with the thing not getting away. Right? Cause if this big snake is latched on, they don't have to run it down after it dies. It's still here.

Ellen: I feel like a lot of venomous snakes do that catch and release thing, right? Where they bite and then back off because they're relying on their venom to kill the prey, so the prey is not gonna get that far. Right? Like they can just follow it and they know it's going to die soon anyway, but... Or you could just hang on.

Christian: And with smaller animals, of course, this venom is going to be very quick. And the last thing I give it for ingenuity, it can control the amount of venom delivered, even to the point where it can deliver none.

Ellen: Oh, this is a dry bite! I've heard of this!

Christian: Yes. Known as a dry bite. So the effects of a bite from a Gaboon viper can range from no effect to rapid death.

Ellen: So nothing could happen, or you could immediately die.

Christian: So here's the problem. So you don't know. There's no way to know until you've spent enough time to say like, "Oh, okay, I'm still alive. I'm not experiencing any issues. That must've been a dry bite." You cannot count on that.

Ellen: That's true. I want to see that Web MD page that says like, effects may include: nothing, or death.

Christian: Yeah. Well, I mean, there's a whole, you know, spectrum of things that happen in between there. Cause the problem with this kind of venom is necrosis. So you're talking about losing some flesh maybe, or even an entire limb being amputated, depending on how bad it is. So when someone is bitten by a Gaboon viper, they're going to go to the hospital no matter what. You might be life-flown (life-flighted? I don't know) right out of there to the closest hospital. And this is the sort of thing where you're probably gonna need antivenom flown in from the nearest research institute. I think there's one with the San Diego Zoo.

Ellen: Oh gosh. Well, I imagine if you're encountering one in the wild, and you're in Africa and the nearest antivenom is... wherever.

Christian: Well, I mean, yeah, so there's, there's a whole like listing of, you know, who carries what in terms of antivenom for the United States, you know, San Diego Zoo is one of them. I think, the National Zoo is another one. But anyway, so here's the thing: they don't know if it was a dry bite. So you're going to go to a hospital, you're going to be in intensive care, you're going to be on an I.V., they're going to have five vials of this antivenom ready to go. Five to ten, cause it kind of depends.

Ellen: Oh, jeez. Yeah.

Christian: So that's under close, close observation until they, it's like 24 to 48 hours before they could say definitively it was a dry bite.

Ellen: Oh my God. That is so stressful.

Christian: Yeah.

Ellen: That is, I'm secondhand stressed. I feel like we should have talked about the Gaboon viper first so that, we should have done this one first so that the capybara could be our comedown from that. Cause now I'm stressed and I need to think about capybaras and I need to go take a hot bath and eat some leaves.

Christian: So I think this is actually some good advice for any snake bite, especially one that you suspect is a venomous snake. Go to the hospital, try and identify what the snake was.

Ellen: So what you're saying is I should get out my phone, and make sure that I get a good in-focus picture of the snake, and then post it on iNaturalist and then wait for three to five verified species IDs...

Christian: Uh-huh.

Ellen: And then take that to the hospital.

Christian: You will already be dead. So yeah, a 7 out of 10 for ingenuity. I thought its methods are interesting and works to its strengths.

Ellen: So the dry bite is a troll mechanic. You're griefing at that point.

Christian: So yeah, the big range of what can happen depending on how much venom it put inside you.

Ellen: They have a rudeness factor going.

Christian: I saw somewhere it was a graph of different kind of venomous snakes, where it was saying how much in volume of its venom is considered fatal versus how much it typically injects with a bite. For the Gaboon viper, it's something like two or three times the necessary amount, at it's maximum.

Ellen: Oh my gosh. Well, okay, so they live in Africa, right? They're probably like chasing down some pretty big prey. They probably have a good reason to be maxing out that much venom.

Christian: So they eat small and medium-sized mammals and birds. They found specimens that have had ingested giant rats, brush-tailed porcupines....

Ellen: Okay. The porcupine doesn't seem like an intuitive prey for an animal that has to swallow its prey whole.

Christian: So I did a quick Google on this particular porcupine. It is very different from what you're probably thinking of, the North American porcupine. The brush-tailed porcupine, its quills are mostly centered on its tail and less pronounced.

Ellen: Still though.

Christian: Yeah, still, but it's nowhere near as bad as the ridiculousness of the North American porcupine, which is just quills everywhere.

Ellen: Yeah, that just doesn't seem like a good idea though, right?

Christian: I mean, headfirst. Don't throw it up. Please don't throw it up. I can't imagine a worse death.

Ellen: I feel like if I was a snake and I knew that anything I wanted to eat, I had to swallow whole, I feel like I would see the porcupine and be like, hmm, maybe not.

Christian: I bet it's spicy. So, then the last thing that they found in these snakes is what's known as a royal antelope.

Ellen: Royal antelope?

Christian: Fully grown royal antelope, and these are the world's smallest antelope.

Ellen: Aww! See you talked it up like this thing had a fully grown adult antelope in its belly and then it's like, Oh it's a little one.

Christian: So this is what prompted me to look up some information, cause that sounded a little farfetched. Because I'm thinking like, full deer size, but it's not. It is the world's smallest antelope, it is 50 centimeters long and weighs 3 kilograms.

Ellen: It's just a teeny!

Christian: Like, 5 or 6 pounds.

Ellen: It's just a baby!

Christian: Yeah, it's cute, and snake food apparently. Moving on to aesthetics, this one was pretty straightforward. I was very impressed by its coloration and its camouflage. I gave it a 9 out of 10 for aesthetics. So, yeah, we talked about this, the pattern on its skin, its head shape, very leaf-shaped and it has a little... Kind of like a upward spike on its like, nose.

Ellen: It makes me think of Jasmine from Aladdin, it makes me think of her shoe.

Christian: Oh, okay. I can see that.

Ellen: Yeah.

Christian: Their eyes are interesting too. You know, snake eyes are always interesting to look at. But finally, my last point for aesthetics is chonk.

Ellen: They're very plump and it's very pleasing. They kind of plop down on the ground, right?

Christian: But again, do not touch! Don't do it!

Ellen: You know, and what sucks is that they look soft, too. Don't they?

Christian: Don't touch that they forbiddien cuddle noodle.

Ellen: It's a dangerous noodle.

Christian: Don't do it.

Ellen: But they look so soft and they look so fat and they look like you could give them a big old hug.

Christian: I wouldn't, though!

Ellen: Hey, I might be fine, though.

Christian: I mean you wake up every day, you don't know if you're going to live or die. What's the difference?

Ellen: Listen, I'll roll those dice. I don't care.

Christian: So that's my aesthetic score, 9 out of 10. Some more wrapping up information: the conservation status is actually not evaluated.

Ellen: Really?

Christian: Yeah.

Ellen: That's surprising.

Christian: Yeah. I thought it's a little interesting with its reproduction. So they usually mate in the rainy season in Africa, which is from September to December.

Ellen: They bless the rains down in Africa.

Christian: Yes. Excellent. In captivity, they can simulate this by just spraying them with water to uh, grease the wheels, if you will. Uh, they have a seven month gestation period. They give birth- here's the surprising part- to 50 to 60 live babies at a time.

Ellen: Live babies!

Christian: Yes.

Ellen: And also that's very many.

Christian: Yes. Evidently, most vipers give live birth.

Ellen: Okay.

Christian: Yeah. I didn't know that.

Ellen: Okay, this is that viviparous life.

Christian: Yeah. The young, they're born up to 30 centimeters, or 11.8 inches long already at birth.

Ellen: Okay, hold on. So go back to the thing you said about how many.

Christian: Yes. 50 to 60.

Ellen: 50 to 60, and each one of them is like, pushing a foot long.

Christian: That's their max. That is their max.

Ellen: [stressed sigh]

Christian: And they already have the same coloration and patterns as the adults when they're born.

Ellen: My thoughts and prayers are with the Gaboon viper.

Christian: There's no real parental care after being born.

Ellen: That's kinda what reptiles do. They kinda...

Christian: Except for alligators, I guess.

Ellen: Gators are good moms, compared to the rest of the reptiles. The rest of the reptiles are like, all right, go do your thing.

Christian: I think we talked about this, but if a little baby gator is calling someone, you probably want to put it down.

Ellen: If they're making a sound, you want to go ahead and leave.

Christian: That's its call for mama.

Ellen: Yeah. And she's comin'.

Christian: Yeah. And then finally their lifespan is around 20 years.

Ellen: That's a long lived snake, huh?

Christian: Yeah, so that's the Gaboon viper.

Ellen: This is such a good snake. It's so satisfying.

Christian: Yup. You can see them in lots of zoos. If you find yourself in a position where this is relevant, do not touch, do not pick up.

Ellen: You know what, with any sort of creative pursuit, you always feel like you've put something good into the world and you want to feel like you've had an impact. If we can save one person's life by letting them know not to touch Gaboon vipers, I would like to hope that someday, someone is out there like, trekking through the African forest and they come across a Gaboon viper, and you see them like, slowly reached down to touch it and then you see them just like think for a second... And your voice echoes through the chamber of their memory and they're like, "Wait, Christian from Just the Zoo of Us told me not to touch these things... I might be okay though."

Christian: I hate that guy! I'm gonna do it anyway!

Ellen: Said, "I remember distinctly him saying that they're gonna bite me, but I might be fine. Nothing might happen. I'm gonna go for it."

Christian: Yeah, I mean...

Ellen: Don't do that. Don't flip that coin.

Christian: Gotta break some eggs...

Ellen: To make an omelet? Is that what you're talking about? What's the omelet here that we're trying to make?

Christian: Knowledge. That's all I got.

Ellen: Okay baby. Thank you so much. You did a great job.

Christian: Thank you.

Ellen: That was a lovely snake. Thank you for talking about it. So thank you so much to everybody who has been tuning in and listening and spending this time with us. Also, thank you to everybody who has been reviewing us on your podcatchers, and especially thank you to people who have been recommending us to your friends and family and cohorts and comrades and all that good stuff. So, thank you so much for doing that. It means a lot to us. You can connect with us on Facebook, Twitter, or Instagram. Just search the title of the show. You'll get there. I promise. If you have an animal species that you want to hear us talk about, you can either get those to us on social media. It would be really cool if you tweeted them at us. I would like that. That'd be fun. Go ahead and do that.

Christian: Do it!

Ellen: Tweet them at us! But you can also email them to me at ellen@justhezooofus.com. A transcript of this episode will be made available at justthezooofus.com, and last note, thank you Louie Zong for the use of your song "Adventuring" off of the album Bee Sides.

Christian: Thank you, thank you.

Ellen: We love it. In fact, it's playing right now. Bye!

Christian: There it goes! Bye!

24: Tardigrade & Platypus

Ellen: Hello Weatherfriends, this is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast where we take your favorite species of animals and we review them and write them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: We are not zoological experts. We do a lot of research and we try our best to make sure we're presenting information from trustworthy sources.

Ellen: This is a no fake news zone.

Christian: I'm going to source Lord of the Rings.

Ellen: Dragonology, from Ernest Drake. So Christian, last week I went first. So that means it's your turn.

Christian: What I bring to us this week, the whole internet asked for it. We're bringing it. That is, of course, the tardigrade.

Ellen: Finally.

Christian: Yes. This was submitted to us by Bo Gantt as well as the Nagging Naturalist.

Ellen: Thank you both.

Christian: Thank you, thank you.

Ellen: Excellent taste in friends.

Christian: I'll be pulling my information from livescience.com, and also one other source that I will quote as I'm using it because it kinda gives something away. So, kind of diving right in. You'll notice I did not say a scientific name.

Ellen: That's right. What's that about?

Christian: So the first thing I'm talking about, and also the first thing I learned: "tardigrade" actually describes any micro animal belonging to the tardigrada phylum.

Ellen: Oh that's a lot of... That's a very high level of classification.

Christian: Yes it is. So, it consists of over 1100 species, so I didn't even try to pick one.

Ellen: Okay. Broad strokes, folks.

Christian: Yes. So they are microscopic. I think a lot of people have heard or seen a lot about these on the internet in recent years.

Ellen: They're quite trendy.

Christian: Yeah. So their size can actually range quite a bit, relatively. So at their smallest, they're 0.05 millimeters long and at their largest, 1.2 millimeters long. So in inches, that's 0.002 inches to 0.05 inches.

Ellen: This is maybe the follicle of a chicken?

Christian: I've actually got some size comparisons to put this into perspective, cause that's one of those impossibly small things for us humans to think about. So to put that in context, the side of a single grain of ordinary table salt, so a single grain, imagine the tiny little cube, the side of one of those is about 0.3 millimeters long. So that means, at their smallest, you'd be able to line up six tardigrades end to end on the side of that grain of salt. While that their largest, it would actually span across four grains of salt. I mean, so while, you know, we're still at a small scale, that's still a pretty big range, right?

Ellen: That's true.

Christian: It's a whole magnitude, or actually a whole two magnitudes larger. Right?

Ellen: That is very much, yeah.

Christian: So partially that's because we're talking about a whole phylum, lots of different species in there. And talking about what they kind of look like, they're also known as water bears.

Ellen: I've heard that.

Christian: Yeah. To me, they look like worms with four sets of legs and a weird mouth.

Ellen: Yeah, they do have a bunch of legs, a whole bunch of little fat wiggly legs.

Christian: Yep. Cause they kind of swim.

Ellen: And then a little trumpet mouth.

Christian: Yeah, yeah. A telescoping mouth, kind of like an alien, like from the alien movies.

Ellen: Yes, definitely. When you see it, it does not look earthly.

Christian: Yeah. So the next part we'll usually talk about is taxonomic family. So again, we're talking about an entire phylum, which is comprised of 20 different families. I'm going to jump into our first category: effectiveness, which describes their physical abilities and attributes, how well they do the things they do. So for the tardigrade, I'm giving it a full 10 out of 10.

Ellen: Woof. Wow, that's a lot for a little tiny dude.

Christian: Let's talk about why.

Ellen: Okay. Please do. Please explain yourself.

Christian: They've been around for millions of years, millions. They've survived all five mass extinction events that we know about that has happened on the planet earth.

Ellen: They're not going anywhere.

Christian: They can live pretty much anywhere, but you'd normally find them in bodies of water, or in places that are wet in general.

Ellen: I guess that explains the water bear part of their name.

Christian: Yeah. And according to the paper "Survival of Tardigrades in Extreme Environments: A Model Animal for Astrobiology" by Daiki D. Horikawa, they can go into a state known as anhydrobiosis.

Ellen: Anhydrobiosis. Is that all one word?

Christian: It is.

Ellen: It's a big word. What's it mean?

Christian: So what that means is when all water is removed, it puts itself into a state of suspended animation. So while in that state, they have a high tolerance to ionizing radiation, a wide range of temperatures, the vacuum of space.

Ellen: Sure. Why not?

Christian: High pressures, they've actually survived open space travel through low earth orbit.

Ellen: Open space travel, meaning they're just like expose to space?

Christian: Yeah. While in low earth orbit.

Ellen: But why?

Christian: They wanted to see. So in those temperatures I mentioned, by the way, the range of temperatures they can withstand in this state are from -328 degrees Fahrenheit to +300 degrees Fahrenheit.

Ellen: Oh my goodness.

Christian: In Celsius, that is -200 to 148.9.

Ellen: Okay. So is this only while they're in that suspended animation state or can they...?

Christian: Yes. Because this, this is important. So I think a lot of people have heard that, oh they can survive anything. But a lot of that comes from while they're in this state. Cause while they're in this state, you know, it's specifically designed to keep them alive. So if they were suddenly in water, and now they're in space, I don't think it would work. Or suddenly exposed to these types of situations, although I don't, I don't know how quickly it can transition into this state.

Ellen: So they kind of go comatose. Right?

Christian: Yeah. So they basically slow down their metabolism to what is virtually a zero.

Ellen: Does that still count as them being alive though?

Christian: Yes!

Ellen: Does that count as them surviving? Cause they kind of are dead for a while.

Christian: Well, they come back from it. So when, when they're reintroduced to water, they come back after a couple of hours.

Ellen: This is like, um... What are those little sponge animals that you put them in water and then they unravel and turned into a little dinosaur or whatever?

Christian: Yeah. Basically.

Ellen: Just add water.

Christian: So when they go into this state, it also has special physical adaptations to avoid crystals forming when it freezes.

Ellen: Oh wow.

Christian: Cause that's, that's one of the most important things about when you're trying to freeze something without killing it, is not producing ice crystals. Cause those will puncture and burst the lining of cells. So that's the danger with freezing.

Ellen: So what do they do to not freeze?

Christian: So for that one, it has to do with the shape of its body. So when it enters this kind of state, it turns into a ball, or also known as a tun.

Ellen: A tun?

Christian: A T-U-N. Yeah. So it pulls its legs into its body, and so, and kind of turns into a ball.

Ellen: Okay. It kinda makes sense because I imagine when there's less surface area, there's just less available real estate for ice crystals to form on.

Christian: Yeah. So ice crystals are a little bit of a complicated topic. They have a lot to do with pressure and the speed at which the temperature changes. So I know back from my high school days, some of the best ice cream I've ever had was ice cream created with liquid nitrogen and that's because of the speed at which the cream and the sugar freezes prevents big ice crystals from forming, so it has a more smooth texture.

Ellen: Sure. Couldn't do that with the tardigrade, though.

Christian: I mean honestly, we've probably eaten thousands of tardigrades in our lifetime.

Ellen: Oh, gross! Aw, man!

Christian: Just putting that out there.

Ellen: This show is canceled. How come you keep doing this?!

Christian: Welcome to the microscopic world. So, 10 out of 10 effectiveness, they cannot die. And I for one, welcome our new overlords.

Ellen: If they could ever get over the size of a hair.

Christian: I believe one of the Ant Man movies features these guys, by the way.

Ellen: Oh yeah. I think I remember seeing them floating around in there.

Christian: On to ingenuity, how smart they are. Examples of this could be tool use, interesting techniques in combat.

Ellen: Pro strats.

Christian: Yeah. This guy has none of those. 1 out of 10.

Ellen: Oh, he min maxed.

Christian: They know how to eat and reproduce. Moving on.

Ellen: Oh my god these poor babies.

Christian: Well, just real quick what they eat, which is interesting. They eat fluid from other things, like algae, lichens, moss and even other microscopic animals including other tardigrades.

Ellen: Oh- wait. Okay. Hold on. So they eat fluid from these things?

Christian: Yes.

Ellen: What type of fluid? Do I want to know?

Christian: Well, you know, water-based protein stuff, the innards of other microscopic things.

Ellen: Gross. Okay. All right. Sure.

Christian: Moving on to aesthetics, how cute they are, how beautiful they are, or how the opposite of those things they are.

Ellen: I mean, you can't really see these guys. Right? I feel like they have to be disqualified.

Christian: So under a microscope, I would give these guys a 6 out of 10.

Ellen: Okay, that's fine.

Christian: They're sort of cute, I guess.

Ellen: You know what I think they look like?

Christian: What?

Ellen: Manatees.

Christian: That just reminded me of another one of their nicknames.

Ellen: What?

Christian: Moss pig.

Ellen: Moss pig. They look more like pigs than bears. I'll give them that.

Christian: Yeah. So like I mentioned earlier, they have four pairs of legs, the weird alien telescoping mouth. They also are chonk.

Ellen: They are, oh, they're so fat and round. They look like if you, uh, like touched them in any discernible way, like if you were able to, it looks like they would maybe have the texture of a balloon.

Christian: Yeah.

Ellen: Or like they look- they look inflatable to me. They look like a balloon animal.

Christian: Like you would see on a parade route or something.

Ellen: Yes! Oh my gosh! Macy's Thanksgiving Day Parade. Tardigrade float. I got to see it.

Christian: But it's, like, flesh colored and...

Ellen: Ooh... No.

Ellen: So yeah, that's 6 out of 10 for aesthetics.

Ellen: I think that, thinking about the way that the tardigrade looks, I think that the color that they are has a lot to do with how cute I think they are. Because once you suggested flesh colored, they stopped being cute immediately.

Christian: Well, I think colorations of these guys are usually... Like someone colored it after the fact.

Ellen: Oh sure. Like CGI, sort of.

Christian: Something like that. So because usuallym I think under the microscope, they're mostly transparent.

Ellen: That makes sense.

Christian: Yeah. Or, if you see electron microscope images of them, they just have to pick a color for that. That's not really what the color is.

Ellen: Hmm. Uh, I'm gonna say purple. I think they're purple.

Christian: Yeah. So conservation status, not evaluated.

Ellen: Wow. Surprise, surprise.

Christian: Probably not hurting.

Ellen: Probably fine. I mean, if literally five consecutive extinction events couldn't take them down, I don't think we have to worry about them. I don't think they need our help is what I'm saying.

Christian: They'll probably outlive us, in all honesty.

Ellen: We probably need help from them more than they need from us.

Christian: So earlier I mentioned the anhydrobiosis, that is actually one kind of what's known as cryptobiosis

Ellen: Crypto... biosis?

Christian: Yeah. So this refers to, just states in general that it goes into to avoid dying.

Ellen: And this is just one?

Christian: This is one kind. So this one is water driven.

Ellen: Okay.

Christian: They can also do anoxybiosis. So this is when the water they live in is low in oxygen, because they still need oxygen. They normally absorb oxygen through their... I say skin, but it's really whatever that outer layer is.

Ellen: Their membrane.

Christian: Yeah, yeah. So during this state, they stretch out and lower their metabolism. So they stretch out their legs...

Ellen: Awww.

Christian: So increasing surface area.

Ellen: There you go.

Christian: And their muscles are able to absorb enough oxygen to survive.

Ellen: Okay. That makes sense. Interesting. Do you- would you find these guys typically in freshwater or saltwater or does it matter?

Christian: I believe both.

Ellen: Okay.

Christian: Um, and usually close to the bottom with like silt and that kind of thing.

Ellen: Oh, sure, sure, sure. You're not going to find them just like floating around?

Christian: You probably could. I wouldn't look for them there.

Ellen: I wouldn't look at them at all.

Christian: I mean, cause all you'd be doing is like, I don't know, collecting some water.

Ellen: And just hoping for the best.

Christian: Getting like, an eyedropper and putting it on a microscope slide.

Ellen: Oh my God. I cannot imagine something more boring.

Christian: So yeah, that's the tardigrade.

Ellen: Very good. That's a good friend. It's a funky little dude, huh?

Christian: It is.

Ellen: I feel like they, in recent years, have had quite a few crests and troughs of popularity. You know, I feel like they will spike every once in a while where suddenly everybody will be talking about them all the time, and you'll see a bunch of like memes about them and stuff like that. And then people will kind of get burnt out on them and forget about them for like a year or two, and then all of a sudden everybody will talk about them again.

Christian: I think part of that is because the studies around how they handle space have been done in the past decade or so.

Ellen: That makes sense. That's true. We were just talking very recently about that thing where a bunch of tardigrades, what, crashed on the moon or something like that? There are a bunch of tardigrades on the moon.

Christian: I mean, if they're there, they're in a suspended state so.

Ellen: There's probably like a whole bunch of them just floating around in space. What if they're aliens though? Have you considered that? Have you considered that they might be aliens?

Christian: Maybe.

Ellen: Okay, so. Hear me out.

Christian: Uh-huh...

Ellen: ...They're aliens. That's all the details I have.

Christian: Okay.

Ellen: What if- wait, you said there are millions of years old?

Christian: Yeah.

Ellen: How old? Were they around at the same time as dinosaurs?

Christian: Before, probably.

Ellen: Oh, okay. I was about to say, like, or did they just mysteriously appear coincidentally at the same time as the giant meteor that wiped out the dinosaurs?

Christian: You know, I wasn't there at the time.

Ellen: Okay, Christian. Play with me in this space.

Christian: I'm over here dodging dinosaurs with the microscope.

Ellen: Like, "hold on, I need to take water samples!" I'm saying, okay, so you weren't there so you can't technically prove that they didn't come in on the giant meteorite that wiped out the dinosaurs.

Christian: Do you come in on that meteorite? Dun dun dun!

Ellen: I'm just saying you've only known me for a few years so you don't know either.

Christian: Matrix.

Ellen: That's not what that movie was about.

Christian: Pretty sure I remember there being dinosaurs.

Ellen: No, that was Keanu Reeves. I know you always get them confused.

Christian: Okay. That's the end of my thing.

Ellen: Thanks babe. You did great.

Christian: Thanks.

Ellen: Before we move on to my animal, I just want to let y'all know real quick that we have a Patreon and it has some really cool stuff on it like access to a feed of the show with no ads so you can skip the commercials, and also some other really cool stuff like we send out photo prints and a patron only discord and all sorts of really neat stuff. So if you want to support us and help us grow and help us get bigger and better, just check us out at patrion.com/justthezooofus, and for this week I would like to thank our patrons, Briana Feinberg, Krystina Sanders and the Jungle Gym Queen.

Ellen: Thanks y'all.

Christian: Thank you.

Christian: Alright Ellen, what do you bring to this animal space this week?

Ellen: Well I suggest you settle in, get yourself a drink, a blanket, get nice and comfy cause we're going to be here a while.

Christian: Well, I'm sitting.

Ellen: This week, I have the platypus. Okay. I should specify: the duck-billed platypus, being the mammal. There is a apparently a type of beetle that's also called the platypus. And this is not that.

Christian: You can't just jack a style like that.

Ellen: Well, tell that to the people that named the platypus.

Christian: Dear beetle people...

Ellen: No, it was the mammal people that named it the platypus that had already had that name. Like the beetle had the name first.

Christian: Dear beetle people, get over it.

Ellen: Get over yourselves. Honestly. Make way, there's a new platypus in town.

Christian: So what is the word platypus... Does that have some sort of significance there?

Ellen: It comes from Greek, meaning flat foot.

Christian: Ah, okay.

Ellen: Yep. So the scientific name for the platypus is Ornithorhynchus anatinus. And this species was submitted by Stephanie Phengchanh, Erica Carr, and the Jungle Gym Queen. So thanks y'all! And I'm getting my information from the Australian Museum and Queensland Government's Department of Environment and Science. If you've never seen a platypus before, it is a little mammal. It's furry, it's brown, has big thick tail and has a big leathery bill on the front of its face, just like a duck.

Christian: Leathery?

Ellen: Yes. Don't worry. I'll explain a little more later. Okay. They are about 20 inches or 51 centimeters long, and about 3 pounds, or 1.36 kilograms. So maybe like a cat, cat-sized but with very short stubby little legs. Not as tall as a cat, but about the same body size. You can find these little dudes in Eastern Australia and Tasmania throughout freshwater river systems. Their taxonomic family is called ornithorhynchidae. Now, taxonomy for the platypus. Boy, it's a roller coaster. It's a wild ride. The platypus is the only surviving member of its taxonomic family. Its closest living relative- you know, what do you think its closest living relatives are? If you could pick, there's literally only one animal on this planet that you could- well I mean it's four different species of a type of animal, but there's literally only one animal in this world that you could say they're related to. What do you think it is?

Christian: For some reason, I don't know why it is, but I think of the echidna.

Ellen: Ah, you got it. It's the echidna!

Christian: I must have read that somewhere, then.

Ellen: Yeah, probably. Um, so yeah, their only living relatives are the four different species of echidnas. So platypus and echidnas make up the order monotremata, these are monotremes. Have you ever heard this word before? Monotreme?

Christian: I think so, I don't remember what it means.

Ellen: It was one of those ones that I heard it and I was like, it was definitely one of the terms bouncing around in my brain but it didn't necessarily- I didn't know off the top of my head what it meant. So I looked into it. Don't worry. These are the only egg-laying mammals, and their name "monotreme" is actually a reference to the fact that they have a cloaca. So both the egg laying and the cloaca are traits that are shared by reptiles and birds, but not by any other mammal. So there are actually a few ways in which the platypus is strangely similar to reptiles and there's a reason for that. The reason for that is that monotremes diverged from the non-egg-laying mammals, that lineage being called the "therian" line, like the therian mammals are the non-egg-laying ones. So monotremes diverged from the therian lineage about 166 million years ago.

Christian: Wow.

Ellen: Yes. And the therians include both placental mammals and marsupials.

Christian: Okay.

Ellen: So monotremes split off before even them. So long, long time ago. So just to put that into some sort of perspective, because it's a very long period of time: cetaceans, which are whales and dolphins and stuff like that, they branched off from the rest of the even-toed ungulates and started to transition into becoming aquatic 50 million years ago.

Christian: Wow...

Ellen: Yeah. So that was like, a third of the amount of time that monotremes were split off from mammals, and they turned into whales.

Christian: Which is crazy, by the way.

Ellen: Yeah. So that's just to kind of give you some perspective of the sort of timeframe we're working with here, that they've been separate from other mammals for 166 million years.

Christian: Gotcha.

Ellen: This is why you'll, a lot of people will call the platypus sort of primitive in some ways because it has a bunch of traits that are left over from reptilian ancestors that the rest of the mammals don't have any more. They got rid of those traits, but the platypus still has them. You can call them primitive in the sense that most mammals don't have those traits anymore, but I mean the platypus is still alive. It's still here. It's not primitive. It's still here.

Christian: This probably suggests there were more monotremes like them at one point.

Ellen: Oh yeah, definitely.

Christian: But now this, you know, this small group is just what's still here.

Ellen: Yeah. So platypus and echidna both live in Australia, but there was at one point a line of monotremes that lived in South America because way, way, way back during, you know, the times when the continents were not where they currently are, South America was on the same like mega continent with Australia. So there was a branch of monotremes that landed there, and then after they split, they were still there, but they've died off by now. Yeah. But so just to give you a sort of idea of what kind of anatomical mess we're about to get into with this animal, the platypus is quite the unique little delight.

Christian: Alright.

Ellen: Yes. So I'm going to start with effectiveness just like you did. I give the platypus a 9 out of 10.

Christian: That's very good.

Ellen: It's excellent. First up, I want to talk about their bill because that's probably the most noticeable feature of the platypus. So though it is kind of shaped like a duck's bill, the platypus bill is not as hard and rigid as a duck's bill is. You know, like a duck's bill is kind of similar to like, bone or something like that. It's very, very hard. Um, the platypus bill is not like that. It's actually covered in a leathery skin, though it does have bone support. So if you look at the skeleton of a platypus, if you look at their skull, they actually have bones going into the bill, and like they form the sides of the bill, but the front- they like curve inwards and stop. The bone doesn't go all the way around.

Christian: Okay.

Ellen: The bone doesn't form the entire bill. It just kind of provides the support for it.

Christian: Sure.

Ellen: And the rest of it is skin. So now here's where the bill kind of pops off a little bit. Inside of this-

Christian: Like literally pops off?

Ellen: No, it doesn't literally pop off.

Christian: Just like the cartoons!

Ellen: No, it's not like that. It's not like Daffy Duck when he like, something explodes in his face and his bill like, turns around to the back of his head.

Christian: Duck hunting season.

Ellen: No, this is where the bill gets wild. The bill is equipped with both mechanoreceptors and electroreceptors. So it has these little sensors in its bill that can detect changes in pressure as well as electrical pulses in the water around them. And these are electrical pulses that are made by muscle movements of its prey. So if anything's moving around in the water, it can not only feel like the actual movement, but it's actually detecting the tiny, tiny, tiny little electric signals that your muscles are sending out. That's insane.

Christian: Yeah. I mean that's like sharks, right?

Ellen: Yes. This is the same sort of mechanic that you see in sharks and stingrays, which is wild! That's insane. Like, so echidnas actually have a little bit of this, not to the same degree that platypus do because platypus do, you know, all of their hunting and feeding in the water and echidnas don't. Echidnas are terrestrial. So it's thought that the reason that echidnas have some of those leftover electroreceptors is that they come from the same ancestor as platypus, they just don't need those receptors anymore. So they're kind of vestigial, really.

Christian: Sure.

Ellen: They don't need them, but they just still have them because they haven't necessarily lost them yet. Because they're not hurting them. Right? So it's pretty interesting. So yeah, these electroreceptors help the platypus find really, really small prey, even in really, really murky water. So when they're swimming around in very murky water, what they actually do is they close their eyes completely while they're diving. So they close up their eyes, they close up their ears and their nose and everything and they are diving around in the water guided only by sensing electric signals. Really crazy.

Christian: Yeah, for sure.

Ellen: It's very cool.

Christian: So, what kind of bodies of water, is it usually a moving water? Stagnant water?

Ellen: It could be moving water, but it's not very deep. Think like, streams and rivers and...

Christian: Sure.

Ellen: Not very deep water because they are still semi-aquatic. They're not completely, they don't live their whole life in the water.

Christian: Okay.

Ellen: Yeah. They actually have to come out of the water to breed, lay their eggs, stuff like that. So kind of on like riverbanks, and near ponds and stuff like that. But they can swim and moving water. It's no problem.

Christian: Sure, sure, sure.

Ellen: So they're actually really good swimmers, which I'll get to in a second. But so what they do eat is just little critters that they catch in the water. So these could be like bugs or shrimp or tadpoles, or stuff like that. Now this is what's interesting: instead of teeth, their bills are lined inside with these pads that have ridges on them. And those ridges are what they use, they- what they do is they catch food and then they mash those ridges together and like kind of grind the food with these ridged pads.

Christian: Okay.

Ellen: And that's how they mash up their food and eat it. Yeah. So they don't actually have teeth. They're not the only mammals that don't have teeth though. Like we've talked about anteaters, like we talked about the tamandua, they don't, they don't have any teeth.

Christian: Sure.

Ellen: So it's like, hey, if you don't need them, what good are they doing you?

Christian: There are other non-mammal creatures that have a similar sort of...

Ellen: It reminded me a little bit of the cownose ray's grinding plates that we talked about.

Christian: Yeah.

Ellen: So similar to that, just these plates with ridges in them that they use to mash their food. So next I want to talk about their tail. A lot of people think that it looks like a beaver tail. It does have that sort of same round flat look, but it's covered in hair. I think a beaver's tail is usually just like bald skin, right?

Christian: Yeah.

Ellen: So the platypus tail is very broad and rather than when you're thinking of maybe an otter's tail, you think of something that's narrow and streamlined. This is more of a thick, broad tail. And the reason for that is that they use it for stabilizing themselves while they're swimming, but also for storing fat deposits in their tail.

Christian: That makes sense. I think we, didn't we recently talk about something that does... does that?

Ellen: You're going to have it to be more specific. I'm sorry.

Christian: There was something recently that it was storing fat in a place that I wasn't expecting.

Ellen: Oh, penguins that store fat in their feet, to keep them from freezing on the ice.

Christian: Yeah! That's what it was.

Ellen: Yeah, that was kind of a funny one. But yeah, so platypus store fat in their tail. So that's, that's good for them. That's a good idea.

Christian: I wonder in which dimension does it grow as the fat deposit deposits?

Ellen: Probably the thick factor, right? Like it probably gets more thick.

Christian: What if they get just bigger than they have more speed?

Ellen: What?

Christian: It just gets wider and wider.

Ellen: Oh my gosh. So they, you know what's funny? They actually don't use their tails to generate thrust in the water., like you might expect them to.

Christian: Well, never mind.

Ellen: I'm actually like right now about to talk about that. So I want to get into the Halloween spirit a little bit by looking at the platypus skeleton. It's a spooky, scary skeleton segment. I'm getting this information from an article by the University College London by Jack Ashby, on April 13th, 2018, the title of the article is "A Tour of the Platypus Skeleton" that I found really, really interesting. I really liked it. So this is where I saw like, the platypus skull and everything like that. The skeleton has some really interesting similarities with lizard skeletons, the most noticeable of which being that their legs are held straight out to the sides rather than underneath the body. So this is like a lizard. Like a lizard's legs are splayed out horizontally, that's how the platypus is. They're kind of like a big hairy lizard.

Christian: This kind of explains why I think they look weird when they're swimming.

Ellen: They do look weird when they're swimming. Yes. Yeah. Cause their legs are splayed out to the side. So when you see something like an otter or a an aquatic mammal, like a seal or something, usually their limbs are held very close underneath them. Right?

Christian: Yeah.

Ellen: Platypus, not necessarily, cause they got big old lizard feet. There's one adaptation they have that really gives them an advantage that is very noticeable when you look at their skeleton. Probably not so much when you look at them with all of their skin and fur on, but when you look at their skeleton, you can really tell that their shoulder blades are comically large. Their shoulder blades are just enormous, and they kind of jut out, like to the sides almost. They have just huge shoulder blades, like the bones are just gargantuan! They're so big. So the idea there is that that probably is because it allows for their arm and shoulder muscles to get huge. So they might not look like it, but platypus are jacked. They're just completely ripped. They have like, huge arm and shoulder muscles underneath all that fluffy little fur. Now, the reason for this is that they kind of need really strong arms because they have to dig burrows to nest in, and to raise their babies in, to lay their eggs in and stuff like that. But they also swim with their front arms.

Christian: So just their front arms?

Ellen: Kind of just their front arms. So they're, they're generating their speed in the water with their front arms. Yeah. So they're steering themselves with their back legs and tail, but they're not actually generating thrust.

Christian: Interesting.

Ellen: Yeah. So they're kind of just like pulling themselves through the water with their front legs. So that's why their arms are so, uh, buff.

Christian: And they have webbed toes, right?

Ellen: They do. Yeah. All of their feet are webbed. So that helps them, you know, generate some drag in the water. But yeah, they're just pulling themselves through the water with just sheer muscle. Arm muscle. Pure gains, baby.

Christian: I think I just realized why so many people imagine them having beaver tails.

Ellen: Why?

Christian: Because that show Phineas and Ferb draws it like that.

Ellen: Oh yeah, that's true. You know what's funny about Phineas and Ferb? So there is a platypus on the show named Perry the platypus. If you've never seen the show, it's a cute little show, but they have a pet platypus named Perry the platypus and he is blue, right?

Christian: Like a teal almost?

Ellen: He's like tealish blue and he leads this double life where he's actually a secret agent. He's like a crazy like spy and does all these cool, like saves the world and stuff all the time. But here's the weird thing about Perry the platypus, in the show he makes this weird little noise that I cannot replicate. I looked up a video of the sound that a platypus actually makes... It's pretty spot on. Like it's pretty much exactly the way that they made him sound in the show.

Christian: That's so weird how they were so selective on which pieces to be correct on.

Ellen: It's like the one thing about the show that makes any sense at all.

Christian: I don't think I've ever seen Perry be in a body of water either.

Ellen: Yeah. Like in the show he's just walking around on two feet. Right?

Christian: And also like more modern mammals like with the legs underneath them at all that.

Ellen: Yeah. So that is not correct about the platypus. It's just really weird. Like the one thing that they got right was the sound that he makes.

Christian: Yeah.

Ellen: It's really weird. But so anyway, yeah that's the- that's the platypus skeleton.

Christian: Got it.

Ellen: It has some interesting things about it. So I want to talk a little bit about their self defense because they actually have a little bit of self defense mechanisms, but not like 100%. So the male platypus have sharp spurs on their heels of their hind legs only.

Christian: Okay.

Ellen: And these spurs are connected to glands that produce venom. The venom causes extreme pain.

Christian: Oof.

Ellen: Yeah. So it won't kill a human. It could possibly kill a smaller animal like a dog or something, but it probably won't kill a human. I don't think there's any recorded cases of a human dying from being stung by a platypus.

Christian: Sure.

Ellen: But it will hurt very, very badly. Now this spur, it can be used in self defense, but only males have the spur. So females can be born with the spur when they're babies, but it falls off before they become adults.

Christian: Really?

Ellen: And they lose the spur. So only the males keep the spur and only the males produce venom. So the fact that females don't have this venomous spur leads scientists to believe that they only use it to fight each other, and that the males are using it to fight each other over territory.

Christian: Well...

Ellen: So it's not really super useful for like defending yourself from predators. So I couldn't give them like, full self-defense points for that because it's not really what they use it for. It does, however, make the platypus really dangerous to handle.

Christian: Yeah, I imagine.

Ellen: So if you see one just to go ahead and don't touch it, just leave it alone.

Christian: I mean, the place where I would be to see them, I would hope you would know not to touch anything.

Ellen: If you're already in Australia, just follow the rule of thumb and if you see something just don't touch it. But, so I did deduct one point, and I deducted that one point for how clumsy and awkward they are on the land.

Christian: Yeah.

Ellen: So they're, they're pretty good at swimming around. They're good swimmers, they're good diggers. But when it comes to actually walking around on land, the combination of how short and stubby their legs are and how splayed they are to the sides, and also the fact that they have webbed feet, it just makes them really bad at walking around. They're just bad at it. Maybe I wouldn't have taken off a point for that if they didn't have to come on land sometimes. Right? They're not fully aquatic.

Christian: Sure.

Ellen: So they're just kind of trash on land. Yeah. So if one is chasing you down, you'll be fine. So that was my deduction. Now here's a weird one. I did not either reward or deduct points for this, I just wanted to talk about it and I didn't know where else to put it, so here you go: platypus and echidna do not have stomachs. They just don't have them. So the food goes straight through the throat, into the intestine and that's it. So this is really interesting. I got this information from a National Geographic article by Ed Yong titled "How the Platypus and a Quarter of Fishes Lost Their Stomachs." This was from December 3rd of 2013. It is kind of thought that because their diets are really, really high in shellfish, shellfish are high in contents that neutralize stomach acids. So there's no point in having a stomach that produces digestive enzymes if all of those enzymes are just going to be canceled out anyway by the kind of food that they eat. So it's kind of like a waste, I guess, of metabolic activity to even have a stomach at that point if the things that you're eating don't require any sort of stomach acid to break them down. So they've just kind of skipped the stomach altogether. Now that's just like a suggested- an idea about why they don't have stomachs. And it's really weird because the only other vertebrates like this are a bunch of fish. It's just monotremes and then some fish. No reptile is like this. No bird is like this. No mammal is like this. It's just monotremes and like, some types of fish.

Christian: Crazy.

Ellen: Platypus, what are you doing? Platypus. Get your life together. What are you doing? Why are you doing this?

Christian: When you say no to updates for too long.

Ellen: They just opted out of the Windows update. You know what they, they kept hitting "remind me in 4 hours" for 166 million years. That's, so that's the effectiveness for the platypus.

Christian: Neat.

Ellen: This is a weirdo, but I love him for it. So ingenuity for the platypus, I couldn't find a lot on them and like, their behavior in the wild. I gave them a 6 out of 10 because they seem like they know what they're doing well enough, but I mean, nothing spectacular. So something that they do that I thought was really interesting that helped them turn a weakness into a strength: to help them with mashing up their foods, since they don't have any teeth, they'll sometimes scoop up gravel or pebbles with the rest of their food and roll it around in their mouths to help break up the food that they're eating.

Christian: Okay.

Ellen: Yeah, so we a little bit talked about the axolotl scooping up rocks and using rocks to help it, but that was more for a balance thing. That was for like, to supplement its buoyancy. This is different. The platypus is not like, eating the rocks. It just will scoop them up in its bill and then use the rocks to help break down the food that it's eating.

Christian: Man, if only it had some sort of thing in its mouth that was hard as a rock...

Ellen: If only there was, if only there was some sort of bony structures that they could have in their mouths that might let them break food down. I don't know if there's any sort of animal that has anything like that in their mouth, but maybe it's something they could consider looking into. So I want to talk a little bit about the reproductive cycle of the platypus, or at least the sort of life cycle of the platypus since it's, since it is so different from other mammals. Right? So after mating the female loads up on food and she fills her tummy and her tail, of course, with fat. And then what she does is she digs herself a little nesting burrow with those big buff, very strong arms. She digs herself a little nest, she climbs inside and then she actually blocks off the entrance with dirt. Yeah. So she covers up her own little nest and she clogs it up. This is both to protect the nest and also to insulate it so it traps warmth and humidity inside.

Christian: Okay.

Ellen: For the duration of her nesting period. So then she lays her eggs. It's usually two, but it could be, it could sometimes be one or three, but it's usually two. She incubates them for a few weeks until they hatch, and then she nurses the baby for a couple of months until they're ready to leave the borrow. So she does produce milk, so platypus do produce milk like other mammals, but not necessarily the way that other mammals do. So she essentially sweats the milk out through these little patches on her skin. So it's a little different from the way that other mammals produce milk. I mean, other than the fact that she, you know, lays her eggs rather than giving birth to her babies, you know, the whole like child rearing process is kind of similar to other mammals where she nurses them for a while and takes care of them in the nest and then kind of sets them free a few months later. So moving on to aesthetics, the last segment for the platypus. I give them a 7 out of 10.

Christian: Okay.

Ellen: They're vaguely unsettling, in some ways, to look at because the bill doesn't necessarily look like it is part of the animal. Right? It looks like it's stuck on.

Christian: Sure.

Ellen: Because so when you think of like, a bird's beak or a duck's bill, it very clearly transitions into the face very smoothly. Right? Like it goes like from bill into the face, whereas the platypus's bill has this sort of like, fold over it. It like rolls in such a way where it definitely looks like it's just like... Kinda glued on. It definitely doesn't look like it's supposed to be part of the rest of the animal.

Christian: Sure.

Ellen: Especially if you're looking at the mammal part of it and thinking like, "oh it's like a little otter or a beaver or something." It definitely is unexpected and very awkward in its sort of design. So you know, famously when the platypus was first discovered by European scientists, they assumed it was a fraudulent hoax and they kind of poo-pooed it and they threw it in the trash because they said like, basically like, haha, very funny, nice troll. And then they threw it away because they didn't think it was real. So there's actually kind of a, a little bit of context for this. The first specimens that made it back to Europe were either skins or taxidermies, but the problem is that around the same time there were a lot of vendors that were selling what they called "mermaids"...

Christian: Oh boy.

Ellen: That were actually just monkeys, like taxidermied monkeys glued onto fish tails.

Christian: Oh, boy.

Ellen: Yeah. So that was definitely happening. There definitely were a lot of fraudulent, you know, people saying, "Oh look at this crazy animal," but they had really just taken two animals and taxidermied them together in some weird way. I think that they were already kind of in a skeptical mood because of that. So I kinda can't really blame them too much for being like, "Oh, this is fake news" and throwing the platypus away.

Christian: This is kind of the basis for that ad series for Lunchables, with the jackalope and the platypus. Do you know what I'm talking about?

Ellen: Is the platypus in that? I thought the platypus had like, something weird about it.

Christian: It's just a regular- I mean, a talking platypus, but an otherwise regular platypus. But the jackalope is just a rabbit, you know, with deer antlers on it.

Ellen: Right. Same- I think they thought it was something like that. Right? Like, oh somebody just thought they were being funny and just like tacked another part of an animal on here.

Christian: Yeah. Yeah.

Ellen: So that's what they thought was happening, and it wasn't until a while later that a preserved specimen was able to make it back in such a way that convinced scientists that it was actually real.

Christian: What century would that have been like?

Ellen: I don't- Oh my God, I do not know.

Christian: Well I was trying to think, could they have just taken a picture?

Ellen: No, definitely before that. One thing that I did want to mention is that there is this picture floating around the internet....

Christian: Oh, yeah.

Ellen: There is a- it's a real photograph that is floating around the internet that is often posted on social media saying that it is a baby platypus. And it is very, very cute. It is very, very fluffy. It has big round eyes and the face of like, a duckling.

Christian: Yeah.

Ellen: It has like a duckling face with little little cute cheeks and big round eyes. And it has one back leg up in the air and the photo is extremely cute, and it is also extremely FAKE.

Christian: Dun dun dun!

Ellen: It is a doll. So the photograph is a legitimate photograph, but the photograph is of a doll. So the doll is made by Russian artist Yulia Leonovich, and it's a cute doll but it was sold like a year ago. It's not available anymore. You cannot buy it.

Christian: And to give the artist credit, you know, that was what the picture was used for, to sell the doll, right?

Ellen: Yes. It was a listing for the item on deviantArt.

Christian: Yeah.

Ellen: So this was a deviantArt picture that got just kind of saved, and then like somebody put it on Instagram or something and then it just took off from there. And now you'll see everybody sharing it saying, "Oh look how cute baby platypus are." And it's like, well okay, this doll inspired by baby platypus is super cute, sure. But it's not real. So let's talk about what real baby platypus look like.

Christian: Yay!

Ellen: They look like little balls of dough.

Christian: I love it.

Ellen: They're not fluffy at all. They have, they have like some... Like baby hairs on them, but they're very, very short. They look like velvet, sort of. And they're extremely chubby. Like they're just little dough balls, and they're covered in fat rolls and they have these teeny, teeny, teeny tiny eyes. And you can't even see their eyes under their fat rolls. That's how fat they are. Yeah. And they look like a mess. Even the adult platypus has really small eyes. So, the baby platypus is cute enough on its own. It doesn't need a doll making people think that they're, like, I don't know. I don't know why this is something that bothers me because honestly, in the grand scheme of things, who cares if you thought you saw baby platypus but it was just a doll. Like who cares? It's just something that bothers me.

Christian: I don't know. So speaking of which, what is the plural form of platypus?

Ellen: I'm glad you asked. I have detailed notes on this.

Christian: Oh boy.

Ellen: So the name platypus comes from Greek, the suffix I suppose, of "pus" at the end, P-U-S, means foot. And the plural of that should be "podes," P-O-D-E-S.

Christian: Yes.

Ellen: So you could make the case that it should be called platypodes or something like that.

Christian: Sure.

Ellen: Nobody says that. Come on. That's ridiculous. Nobody says that. Now some people will say it's supposed to be platypi. That is very wrong, because that is assuming that the -us ending comes from Latin, just because it ends in -us. But it doesn't come from Latin. It comes from Greek, so you do not use a Latin plural ending for a Greek word, so it's definitely not platypi.

Christian: Makes sense.

Ellen: But we're speaking English, so you could say platypuses, that's fine. You can say platypus. That's fine. Don't say platypi. It's definitely not that. Platypodes is... Okay. You sound kind of weird, but it'll pass. It sounds like the Well Actually Guy. So I say platypus, just because I feel like platypuses sounds weird, platypi is wrong, platypodes sounds wrong. I just say platypus. On that note, there is a little thing that floats around about platypus on the internet, where usually as a caption on that exact same picture of the little platypus doll with a leg up in the air, people will a lot of times put a little caption or comment on there saying, "did you know that a baby platypus is called a puggle?" You can call it a puggle I guess if you want...

Christian: I mean, you can call it whatever you want, really.

Ellen: Because language is arbitrary and meaningless. So you know, just make up whatever you want, I guess. But there's also another one, like a similar sort of like internet rumor about what the baby platypus is called that I like way better and it has platypup. That's also totally made up, but I like it better than puggle. So yeah, there is actually no word for the baby platypus.

Christian: I'm so upset.

Ellen: It's just a baby. platypus. So you can call them a platypup if you want, and you can call them a puggle if you want, I guess. But don't expect anybody to know what you're talking about.

Christian: Platyput me out of my misery.

Ellen: Those sound waves don't look good. Those aren't going to be fun to edit.

Christian: Have fun, future Ellen. I love you.

Ellen: Anyway, the platypus is still pretty cute. Uh, it is very otter-like, and you know I'm into that. They have cute little webbed feet and you know I like that. So I dunno. I still think they're on the cute side. Little weird, but cute.

Christian: Are we going to come back to the cloaca thing?

Ellen: The cloaca thing? No, we're not. I was just going to leave it alone. I figured I gave you all the information I needed because this is a safe for work show, so no, I'm not going to go into more detail about the cloaca.

Christian: Okay.

Ellen: It was a thing that I really just wanted to mention to highlight the similarities that it has with lizards that makes it so different from any other mammal. Right? That's just one of those really, really weird things about it.

Christian: Even though looking at them, they look like they would have more in common with birds just because of the bill.

Ellen: That's the weird thing, right? That's one of those weird convergent evolution things, and also their venom is another example of convergent evolution because the venom that they produce shares a lot of chemical properties with venom that is made by snakes.

Christian: Does the platypus hold the title of the only mammal with venom?

Ellen: No. There are other venomous mammals.

Christian: Interesting.

Ellen: There are actually a few... The slow loris produces venom... There are actually quite a few other venomous mammals, but it is a very interesting, and there's just so much about it that is just so bizarre and like the most random stuff, like it not having a stomach. Why? Why? That's so extra. Why would you do that?

Christian: It's the opposite of extra.

Ellen: But yeah, to wrap things up for the platypus, their conservation status is Near Threatened according to the IUCN Red List. So there are a lot of factors contributing to the decline of platypus numbers, but one of the biggest is climate change. There are a lot of droughts and really weird rain patterns that are affecting the freshwater habitats that they live in, but there's also a lot of extraction of water for industry and agriculture that's depleting the freshwater sources that they need to live in. So they're facing a lot of habitat loss and they're also dealing with water pollution in their areas. Pne organization that you can check out if you're interested in helping support the platypus is the Australian Platypus Conservancy.

Christian: Nice.

Ellen: Yeah. So go check them out if you want to dig more into the platypus and see how you can help them out. So that wraps things up for the platypus.

Christian: Thank you honey.

Ellen: No problem.

Christian: It was very interesting.

Ellen: I thought so too. I really enjoyed learning about this animal. I've talked for so long. I've taken up so much of these good people's time, but I'm not done yet. I have some audience responses to share and I kind of farmed for them a little bit. Last week, I talked about the roly poly.

Christian: Yeah.

Ellen: We mentioned a few names for the roly poly, and I kind of was interested to see what other people actually call roly polies because some of the names that I saw listed for them were not known to me. So I posted both in the Facebook group and on Twitter asking people where they live and what they call a roly poly. Most people, according to my graph, 62.2% of people who responded said roly poly. However, the second highest number of responses was for the potato bug. 16.2% of people who responded said the potato bug. And it seemed to be like most of the people who said potato bug lived in the North. People that said potato bug lived in places like the Midwest, Canada pretty much anywhere north of where we live.

Christian: Interesting.

Ellen: Yeah. So the potato bug was pretty common. A few people said doodle bug, the doodle bug, which was represented in North Carolina and Texas. And this was the one that I had never heard before in my life: slater.

Christian: Oh yeah, I saw this.

Ellen: Yeah. So a few people responded from New Zealand and said that they call them slaters, and this was something that I had never heard before.

Christian: Interesting.

Ellen: But yeah, that was interesting. I always feel like we're kind of exchanging information here, right? Like I come on the podcast, I take the microphone and I teach you some things, and then once I'm done, I step away and you guys teach me some things back. So thank you for teaching me the name of the roly poly in New Zealand.

Christian: That's very good.

Ellen: Yeah, that's all I had. I just wanted to talk about the conversation we had about roly polies. So thank you so much for spending this time with us, listening to us talk about our animal friends, the tardigrade and the platypus. This was a couple of unique critters this episode, huh?

Christian: Yeah, they were both taxonomically...

Ellen: Unique.

Christian: I was going to say complicated, but for different reasons.

Ellen: An unintended theme this week of oddballs.

Christian: Yeah.

Ellen: That was our theme this week. Thank you so much to everybody who has been listening to this show and recommending us to your friends and talking about us on Twitter and all that cool stuff that you guys do. You really stoke the coals that keep this flame burning, so thank you. You can connect with us on Facebook, Twitter, or Instagram. Just search the title of the show and that'll get you to us. Please come join our group and hang out with us cause it's really fun and great.

Christian: I'm on discord now.

Ellen: Oh yeah, you are on discord now, aren't you?

Christian: I'm having to get used to using discord for things that aren't video games.

Ellen: It's fun but yeah, we are on the Podcast Junkie discord server, so come hang out with us on there. We have our own channel and it's really fun. If you have an animal species that you want to hear us review, you could submit those to us either on social media or to me directly at my email address, which is ellen@justthezooofus.com, and a transcript of this episode will be available at our website, www.justthezooofus.com and our final note: thank you, Louie Zong for the use of your song "Adventuring" from your album Bee Sides.

Ellen: Thank you so much.

Ellen: We love it.

Ellen: Do I get my email address?

Ellen: No, just me.

Christian: Is christian@justthezooofus.com taken?

Ellen: The problem is that I don't trust you with it, because you will just send me really unsettling information throughout the day. You'll just, I'll be like, Oh, an email from christian@justthezooofus.com, I'll open it up and it'd be like, "you've eaten six tardigrades today," and I'll be like, great.

Christian: I'll program a timer that just...

Ellen: Sends me just really disturbing animal facts every five minutes. Can I unsubscribe from your weird animal fact newsletter?

Christian: Uh, legally, yes. You have to be able to unsubscribe, but anyway.

Ellen: Okay. Thanks. Bye.

Christian: Bye y'all.

23: Roly Poly & Keel-Billed Toucan

Christian: Hi everyone, this is Christian Weatherford.

Ellen: And this is Ellen Weatherford.

Christian: And you're listening to Just the Zoo of Us, a podcast where we rate your animals both favorite and... Opposite of favorite.

Ellen: What's the opposite of favorite, Christian? Quick, hit me with that.

Christian: Extreme dislike. So we take those animals and we give them a rating out of 10 for three categories. I don't remember if we mention those categories here or not, but it just in case we do, here it is future Ellen: effectiveness, ingenuity, and aesthetics! I'm bringing good energy.

Ellen: Christian and I are not zoological experts but we do a lot of research to get ready for the show, and we make sure that the information we're giving you is reliable and it comes from good sources. So feel free to reach out to us if you are an animal expert and want to chit chat about anything we've gone over on the show. We really love that.

Christian: Yes, and a lot of you are actual zoological experts.

Ellen: Mhmm, and we love you. Well, last week you talked about the matamata turtle, and you went first. So this week it's my turn to go first.

Christian: Excellent. What do you have for us this week?

Ellen: This week I am talking about an animal that I'm pretty sure almost everybody in the United States probably has some hands on experience with, but probably doesn't actually know very much about.

Christian: Oh?

Ellen: This is the roly poly.

Christian: Ah!

Ellen: Some other names you might know the roly poly by are the pill bug, the doodle bug or the woodlouse.

Christian: I do like the name doodlebug.

Ellen: Yeah, you know, I keep seeing references to it, but I don't know of anybody around here who calls them that.

Christian: It might be a regional thing.

Ellen: Yeah. For context, we live in Florida, and I don't know of anybody here who calls them doodlebugs. But the name that I have always known them by is roly polies, so that is the name that I will be using for them for the entirety of the segment and also my life. So, sorry. The scientific name for the roly poly is Armadillidium vulgare.

Christian: Okay. So, you know, obviously... Armadillo. Right?

Ellen: Yeah, yeah, yeah. So that's the name of their genus, and it does come from armadillo because they do roll up into a little ball. That's where they get the name roly poly, cause they roll up into a ball. And then "vulgare" comes from the Latin word for like, common. So this is kind of just the common woodlouse, the one that you're going to find pretty much everywhere in our country that we live in. This species was requested of us by the What Are You Podcast, and this is very charming because this is a show about animals by 4-year-old Dylan and his mom, Megan. It's so cute. I was listening to it a little bit earlier today and it's so precious. So we love y'all, Dylan and Megan, and hope you like our bit on the roly poly.

Christian: Excellent.

Ellen: So, uh, before I launch into it, I'm getting my information from the University of Michigan's Animal Diversity Web, as well as a video that I watched on roly polies from PBS's Deep Look series. To introduce you to my dear friend, the roly poly, their adult size is up to a whopping half inch, or 1.27 centimeters.

Christian: Okay.

Ellen: Yeah. It's about the size of your fingernail or perhaps... The eyeball of a chicken. You're gonna find these pretty much all over the world. They've established populations on every continent except Antarctica, and they are originally from the Mediterranean. So they started there, and then they just kinda took off everywhere, so you can find them all over the world now. Uh, but that does not necessarily mean that they are invasive. They're actually pretty good for whatever habitat they live in.

Christian: Interesting.

Ellen: Yeah, they're really cool. Now their taxonomic family. Buckle up for this one cause it's a bumpy ride.

Christian: Okay.

Ellen: Armadillidiidae.

Christian: Nice. Is that all one word?

Ellen: Yes it is. And also, I had to look up how it's pronounced and I practiced it before this.

Christian: Whoa. Good on you.

Ellen: Thank you.

Christian: I cannot say I did the same.

Ellen: I really put a lot of effort into this one because I knew it was going to trip me up, and I wanted my editing process to be easier.

Christian: Alright.

Ellen: This is the family that contains the other woodlice. There are other species of them other than the roly poly, but they're not as cute. So I'm not talking about them today. Sorry.

Christian: Which is the singular and which is the plural?

Ellen: Lice is the plural, and louse is the singular.

Christian: Got it.

Ellen: This is just like mouse and mice.

Christian: Makes sense.

Ellen: Yeah. I'm going to ask you, uh, what other like, common animal do you think is related to the roly poly?

Christian: Um, I would think millipedes.

Ellen: That's an excellent guess, but it is not correct. I'm sorry. Roly polies and woodlice are isopods, which means they are not even a little bit related to bugs.

Christian: Wow!

Ellen: Not even a little bit. They're not related to bugs or millipedes, not insects, not millipedes, none of that stuff. Actually, being isopods, they are terrestrial crustaceans. They are more closely related to crabs and lobsters and shrimp. So they're actually in the same class, Malacostraca.

Christian: Okay.

Ellen: Now, there is actually a pill millipede, which looks and functions exactly like a roly poly. They're easy to tell apart when you see them side by side, but if you were to just see a pill millipede like out and about, you would reasonably guess that it was a roly poly. But they're actually, they come from completely different evolutionary branches.

Christian: Huh. I'll have to look those up later.

Ellen: I mean, they look like a roly poly, I don't know what else to tell you.

Christian: I'm wondering what do I have in my memory? Which one is it?

Ellen: So the roly poly's totally gray and the pill millipede has more of a brownish color and some variation on their colors, whereas the roly poly's pretty much a solid plain gray color.

Christian: Don't worry, I'll get my reality in order later.

Ellen: Okay. We'll figure it out. But so the roly poly and the pill millipede, having nothing to do with each other evolutionarily but looking and functioning pretty much exactly the same way is another example of convergent evolution. I think the last time we talked about convergent evolution was with the vultures.

Christian: Yes.

Ellen: Yeah. So this is way even farther back than that cause these are completely different animals. Um, but so keep in mind, keep that in your head that they are crustaceans and that they come from isopods which come from the ocean. They have come out of the ocean onto the land, so just keep that in the back of your head cause I'm going to revisit that later.

Christian: Okay.

Ellen: To get started on our rating system. I'm going to start with effectiveness. And if this is your first time joining us, we define effectiveness as how good an animal is physically at accomplishing its goals and doing what it's trying to do on a daily basis. So these are physical adaptations that let the animal do their thing. I'm giving the roly poly a 6 out of 10.

Christian: Really?

Ellen: It's okay. It's okay.

Christian: Just tell me it has a rollout attack.

Ellen: An attack would be a strong word to use. But that was the first thing I was going to talk about, was their habit of rolling up into a ball. So there's actually a word for this behavior. It's called conglobation.

Christian: Interesting.

Ellen: Yeah. Which you can see the root word of "globe" in there. Con-GLOB-ation. That's how I remember it, at least. So you use this to describe roly polies, but also the pill millipedes and also armadillos. That's the same rolling up into a ball as a defense strategy. That's, that's how they do.

Christian: Sandshrew.

Ellen: Yeah, just like it. So I gave it some self-defense points for this conglobation thing. So other isopods can't do that because their exoskeletons are not segmented in the same way. So the roly poly has adapted to be able to do that whereas other isopods haven't. So that's definitely something that's like, kind of unique to them. Unique to them and the other members of the Armadillidiidae family, I'll say that. They have another self defense strategy that I did not know about. When they are threatened or stressed, they can actually secrete an unpleasant odor to deter predators.

Christian: Aha!

Ellen: Yeah, I didn't actually know that they did that.

Christian: "I am now round and smell bad!"

Ellen: Same.

Christian: Predator's just like, "I'm confused, mostly. Goodbye."

Ellen: Yeah, so... Now, I really couldn't give it that many points for this because the roly poly is very small and curling up into a ball doesn't really do it very many favors, because there are a lot of predators that have kind of figured that one out. Like, there are a lot of bugs that eat them that have just evolved long noses that can poke inside of their ball and pry them open. Or like, birds have long, skinny beaks so that they can pull them open and like it's just... It's not that effective of a defense. Like they've got it, but it doesn't do much.

Christian: If they happen to be on a steep hill though...

Ellen: There you go. There could be an escape.

Christian: Then they're a moving target.

Ellen: It could be an escape. Yeah.

Christian: Until the hill ends.

Ellen: Yeah. Another effectiveness point that I gave them was for being able to go a surprisingly long time without eating. So in a lab they were documented surviving for up to three months with no food.

Christian: So what is it that they eat?

Ellen: They are detritivores. So they eat rotting plant matter, they eat decaying plant matter, leaf litter, stuff like that. But they also have some sort of herbivorous tendencies where they will kinda eat any plant matter. But most of what they eat is like, dead and decaying plants.

Christian: So the root of that word, is it pronounced DE-tritus or de-TRI-tus?

Ellen: That's a fantastic question. Moving on. So another interesting thing that I didn't know about them that I learned that I thought gave them kind of, I had to give them some props for is that rather than laying eggs on the ground or in a nest, the female roly poly carries her brood of eggs around in a brood pouch called a marsupium. And this is a pouch that she has on the underside, kind of like where you would guess her belly to be.

Christian: Sure.

Ellen: And she keeps her eggs under there, and she just holds them there and carries them around until they hatch. So when they hatch, the baby roly polies have a special word for their baby form. They're called mancas, or maybe it's, it might be mancae, like a-e? This is like one of those weird Latin things where like in Latin, a word that ends in a, when you make it plural, it becomes -ae, but like we're not speaking Latin, so like you don't have to use it that way. I don't know what the plural form is. I'm going to say mancas.

Christian: Okay.

Ellen: But so the little baby mancas, they will actually stay in the mom's marsupium for like a day or so before fully emerging.

Christian: Okay.

Ellen: So yeah, I just thought that was kind of interesting that they've evolved this sort of little egg transportation device. I thought that was beneficial to them because that means they don't have to lay their eggs and then just, you know, leave them there because then that puts the eggs at risk of being eaten or destroyed. I think that like finding a way to protect your babies is a good idea.

Christian: And then when they roll up, the eggs are in the safest place.

Ellen: Yeah. So I gave the roly poly some good mom points.

Christian: Cool.

Ellen: I know I really had to break my habit of talking about all these bad moms.

Christian: Say, did you hear that, quokka?

Ellen: Yeah, take notes. Take notes. So yeah, I thought those were pretty neat. Now I'm going to move on to talk about the deductions I took off for their effectiveness because there's a few.

Christian: Okay.

Ellen: The roly poly has very poor perception. They have eyes, their eyes are on the front and on either side of their little head segment, which I didn't know that. But when you look at pictures of a roly poly, like zoomed in, they're actually kinda cute. They have eyes on the front of their face, but those eyes can't see for squat.

Christian: Okay.

Ellen: The eyes can pretty much only detect the presence or absence of light and that's it. This is not the 4K experience. They can see- they can basically tell whether it's bright or dark, and that's it. They can't distinguish shapes or colors or any of that stuff. So, they can't see real good. They also don't have ears. Like sound is just not an option for them. That's not something they can perceive.

Christian: Huh.

Ellen: Yeah. They don't have ears at all, so sound is not a thing. Now they can detect vibrations. So they have these little tiny, tiny little hairs all over both their feet and their antenna, and kind of like along the underside of their exoskeleton, they have these little hairs and the hairs can pick up vibrations. So they can feel vibrations, and those vibrations are what trigger their conglomeration. So if they feel a heavy enough vibration, then it'll trigger them to roll up into a ball, but they can't hear anything. So that's not an option for them. I was just like, wow, that's garbage. I'm so sorry. That's like, jeez, you're missing out on a lot, my friends.

Christian: I guess for what they're doing, I guess that's all I need.

Ellen: I mean... Sure?

Christian: What are they gonna do run away?

Ellen: They could hide or something? I don't know. But so, yeah, kind of their most important method of perceiving their surroundings is actually chemical sensing. So they pick up chemical signals with their antennae, like I mentioned, how they're covered in those little hairs.

Christian: Sure.

Ellen: And they actually communicate with each other using pheromones, which I'll talk a little bit about in the ingenuity section. The, I kind of have, my biggest deduction for them was that they really didn't fully transition into terrestrial life. They kinda, they came out of the water and they were like, okay, we got the legs... And that's about it. So they still actually have gills.

Christian: Whoa.

Ellen: Yes. They have gills on the underside of their body. Their gills have evolved to have these little air sacs in them that let them breathe air so they don't have to breathe in the water. But they do actually need to keep their gills wet to work. They need moisture in order to function. So that's why desiccation, which means basically drying out is a huge, huge, huge threat to roly polies. So this is why you always see them in the wet sort of in humid areas. You find them in wet dirt and mud and you always find them in places that are like a little bit damp.

Christian: Sure.

Ellen: It's because they need it to breathe.

Christian: Huh.

Ellen: Yeah. Now they cannot swim, by the way, which seems counterintuitive to this whole thing. Cause it's like they really committed a hundred percent to living on land, but were like, "mmm, we're going to keep the gills though." Like why would you go that far?

Christian: It's like someone explained lungs to them once and briefly and then they were like, "yeah, I got this. "

Ellen: Yeah, we got the idea, we got the idea. We'll do that. Yeah. That's really what it is. It's, it's not ideal, honestly. They kind of got the worst of both worlds. Like they need it to be like a little wet but not all the way wet.

Christian: I guess this is also one of the things that really, really separate them from insects cause they have a whole other different way of getting air into their systems.

Ellen: Yeah. With insects it's, it's wild. It's something like, they take air in and then it doesn't go to like any sort of lung place, it like distributes the air over the body?

Christian: Yeah, they basically absorb it through their skin.

Ellen: It's the wildest thing. But yeah, so the roly polies don't do that. They need moisture in the air to breathe, which I think is not a great strat, but what are you going to do.

Christian: Yeah.

Ellen: Anyway, so to move on to ingenuity, we define ingenuity as behavioral adaptations that an animal has that let it like, figure out clever ways of defeating obstacles in its path or figuring out cool solutions to problems they face every day. I gave the roly poly a 4 out of 10 because it is, you know, like that.

Christian: It's probably a little generous, honestly.

Ellen: So what I thought about was that I thought about how I think I gave the sloth a 4 out of 10. I have been, I think I've been generous with my ingenuity scores, but I'm giving the roly poly a 4 out of 10. There's a couple things a roly poly does that kinda help it along. When roly polies are born, what they will actually do is they will try to find a new place to live that's better for them than the place they were born in. So when they're first born, they will actually try to leave. They will try to go as far away as they can from the place where they were born. But then, if it takes too long for them to find a better place for them to live, they'll turn around and come back to the place where they were born. Because they figure, well,, it'll take me too long- Like it's taking too long for me to find somewhere that's good for me to live. I'm wasting energy trying to find somewhere else. I'm going to go back to where I was born because I know I can survive there. So they'll turn around and come back.

Christian: Yeah, that's pretty smart.

Ellen: Yeah, that was, that was a little bit more processing power than I thought they had in the ol' roly poly noggin. So like mentioned earlier, they communicate with each other with pheromones and roly polies actually do kind of live socially. They kind of hang out with each other and they use pheromones to let each other know that they're there, basically, since they can't see or hear each other. Roly polies produce pheromones and signal to each other their presence, but the concentration of that pheromone increases during mating season. So males, when they pick up the female pheromone, they can tell by the concentration of that pheromone whether that female is ready to mate or not. So that's pretty cool.

Christian: Yeah.

Ellen: And also, when a roly poly is kind of looking around for a new place to live, if it moves into an area where it detects the pheromones of other roly polies, that's its signal that this is a good place for me to live because it says, "Oh, there's other roly polies here. That means they're thriving and surviving here. This is probably a good place for me."

Christian: Interesting.

Ellen: Yeah, so it's not necessarily like territory marking how other animals will kind of leave pheromones to let other animals know not to go there. This is kind of the opposite. They're like, "Hey, this is a cool roly polies city. Like, come hang out with us and all of our roly poly buds."

Christian: That's fun.

Ellen: Yeah. They're like leaving little signs like, "Hey, this is good. Come live here. Come live here in roly polytown with us." Actually, some studies have shown that socialization is a really important survival mechanic to roly polies and that roly polies kept in captivity, even when provided with all of the basically criteria that they need to survive, when separated from other roly polies, they die very quickly.

Ellen: Aw...

Ellen: Yeah. They will also cannibalize each other.

Christian: Oh.

Ellen: Yeah. Sometimes.

Christian: Like, living?

Ellen: Yeah, like living. But it's like if one of them is really weak, so if one of them is injured or something like that or maybe if it's like mid-molt, cause they do have to molt their exoskeletons just like crabs do...

Christian: Sure.

Ellen: Then they're kind of in a vulnerable spot and roly polies will kind of eat each other and that's just the way that they do. So, that was just part of the 4 out of 10.

Christian: Welp.

Ellen: I wouldn't describe them as bright. Oh, another thing that they do, I don't know if I mentioned this earlier or not, they will actually flee from bright light. So if there's a bright light on them, they will pick up on that and they will run and try to as fast as they can, they try to find somewhere dark to hide because bright sunlight can dry them out faster and that can kill them.

Christian: Oh, so they think they like, just walked out of the shade or something.

Ellen: Yeah. Like they think there's like, bright sunlight or something and so they just run and try to find somewhere to hide.

Christian: Okay. I was about to say, cause it's kinda the opposite when you're talking about sensing a predator.

Ellen: Yeah, no, it's, it's just the light. Like they, they know that if they're in really bright light, they know that they can dry out more quickly so they will run and try to find somewhere dark.

Christian: Okay, makes sense.

Ellen: Yeah. And it's kinda funny, I read something about how they travel, not in straight lines, but in zigzags that they alternate turning left and right. Like they don't just go straight forward in a path, they turn left and then they turn right and go back and forth like that.

Christian: Wonder why that is.

Ellen: The thing that I was reading said that it was like exploratory. Like they're looking for new resources and they can cover more ground by zigzagging rather than going in a straight line. So I thought that was pretty interesting.

Christian: Okay.

Ellen: They're okay... They're okay. Just okay. I think that typically when we're giving animals scores, most animals that are alive are going to have pretty good scores because they've evolved, right? Like they've gone through millions of years of adapting in ways that are supposed to be beneficial for them and let them survive better. I think that the roly poly is doing so incredibly well and so very populous because they have like, anywhere from 1 to 300 babies at a time.

Ellen: Woah.

Ellen: So I think they're playing the numbers game. I think it's not because they're particularly good at the things that they're doing, but I think it's that they make very many of them.

Christian: That is a strategy.

Ellen: But so, yeah, they're just, they're friendly boys. Like they just, they eat dead plants and we need them to do that anyway. So they're actually like really good for if- Like you want to have them around, because they keep your soil nice and like- a lot of people will see them in like a garden or something and think, Oh no, they're a pest. But they actually don't normally eat live plants, so you kind of want them to keep around because they'll eat your dead plants and they'll keep your nutrients cycling. They're just, they're good to have around. I'm actually going to talk about that a little bit more in a few minutes. Before I move on to that. I want to talk about their aesthetics.

Christian: Okay.

Ellen: Aesthetics is self explanatory. I give them a 9 out of 10. Oh my God, they're so cute.

Christian: Huh.

Ellen: And I thought to myself, when I look at one zoomed up all the way up close, it's going to be hideous and I'm going to hate it and I'm going to be freaked out and I'm going to regret that I picked to do the roly poly to talk about. But then I watched this video, this PBS video, the Deep Look video, and it had all these zoomed up roly polies and they're so cute. It's so cute. They have the little face with the big round eyes on either side of their head and they got the little antenna that they're wiggling around all the time and have all those little feet. And then when they roll up in a ball, it's so cute. I love roly polies. 9 out of 10. And I only gave them a 9 out of 10 instead of a 10 out of 10 because when you look at them from the underneath, it's a little weird. It's kinda gross. Also, roly poly babies are actually really cute.

Christian: Oh yeah?

Ellen: The mancas that I talked about, so when they're born, they're white, they're completely white, and they're kind of squishy looking and I really like those. So yeah, I'm just very charmed by roly polies.

Christian: I'm gonna have to look at all these pictures later.

Ellen: Yeah, they're really cool. So, I'm assuming most people have probably picked up and bothered roly polies before like I have, but this is the, the same one that you're gonna find if you go out. I bet if we walked outside right now, it would take us less than five minutes to find a roly poly.

Christian: It is nighttime.

Ellen: It is. That's why I said that. Cause it's dark. That's when they come out.

Christian: Yeah, but we won't find them.

Ellen: We have flashlights and stuff.

Christian: But it's spooky.

Ellen: Here, we'll set a-

Christian: You know what month it is right now?

Ellen: Oh that's true... Oh it's October. Oh you're right. We're not going out at night.

Christian: Too spooky.

Ellen: Yeah. So yeah, that's my 9 out of 10 for aesthetics. They're very cute. So to wrap things up with the roly polies and miscellaneous information, their conservation status is not evaluated. That is not a surprise. They are doing fine. Do not worry about roly polies. Now, roly polies are detritivores like I mentioned earlier, they eat mostly dead and decaying plant matter. Roly polies are commonly used in bioactive enclosures for captive habitats. So pet owners or anybody who's keeping captive animals, a lot of times they will have what's called a bioactive enclosure. So this is an enclosure for their pet that is sort of self-contained, like a fully functional ecosystem rather than just like, a tank with like some fake plants and some mulch on the bottom. This is like, there is legitimate like soil with plants planted in there that are growing, and bugs and roly polies and all those sorts of things that are living in the tank to sort of move the ecosystem along naturally rather than you having to like, treat it for all this stuff. So I was looking all this stuff up because I was talking to my childhood best friend Laurel who is preparing a bioactive enclosure, and in preparing this bioactive enclosure, one of the things that she was doing was collecting roly polies. So just going outside, gathering them up and toss them in there. And that the roly polies are really, really useful for that. She said that in her enclosure, they're really, really good for cleaning up waste, keeping fungus in check and cycling nutrients to enrich the soil for the plants.

Christian: Yeah, so I guess the key here is to not have an animal in there that would eat the roly polies.

Ellen: She mentioned that, you know, for people who keep things like tarantulas or millipedes or something like that that would bother to eat the roly polies, then yes, they would totally do that.

Christian: Well, but here's the thing. If you have just one clutch of roly polies hatching a tank, that's a huge number of those little guys, isn't it?

Ellen: I would imagine that at that point there just wouldn't be enough stuff for them to eat and they wouldn't...

Christian: Oh, That's where the cannibalism comes into play, I bet.

Ellen: Perfect. That's a self-solving problem.

Christian: Okay.

Ellen: But uh, Laurel also mentioned that roly polies actually need calcium to keep their exoskeleton nice and strong. So she said that for her captive roly polies, she uses eggshells and cuttlefish bones as calcium supplements.

Christian: Where do the cuttlefish bones come from?

Ellen: So, cuttlefish bones are actually really, really common, bird owners give their birds cuttlefish bones. These are the white oval-shaped things. Yup. That's what that is.

Christian: You're blowing my mind. I didn't know cuttlefish... Wait, are these actually from cuttlefish?

Ellen: Yes. And I will relate with you on this because I also did not know that they were actual cuttlefish bones until she told me this like three days ago, and I freaked out because I worked at a pet store where I gave cuttle bones to birds on a daily basis for two years in a row, and not once did it click in my head that those were actual cuttlefish bones.

Christian: I'm still working on the fact that cuttlefish even have bones.

Ellen: Well, it comes from the cuttlefish.

Christian: Yeah.

Ellen: It's not exactly the same as our bones, but it's kind of an internal shell inside of their body that helps them float. A lot of bird owners feed them to their birds for calcium supplements, and apparently they're good for roly polies too.

Christian: That is insane.

Ellen: Yeah, I, I'm not kidding when I say that I handled them every single day for two years in a row and never even once realized that they come from actual cuttlefish. Did not know that. So that's the roly poly.

Christian: Okay.

Ellen: Yeah, I just, I feel like a lot of people probably have handled them many times in their life and probably have very fond memories associated with roly polies, probably of playing with them and digging them up out of the ground and throwing them at your siblings and doing all sorts of stuff like that as kids, so...

Christian: Eatin' em.

Ellen: I'm sorry, what?

Christian: Eatin' em.

Ellen: I saw somewhere on the internet... I saw on the internet that you can eat them, and that people sometimes cook them.

Christian: So...

Ellen: Oh no.

Christian: No. So pop culture references here. Um, do you remember the animated movie that was in Peru? Cusco's New...

Ellen: The Emperor's New Groove.

Christian: The Emperor's New Groove. Do you remember when they went to that restaurant and they had giant pill bugs- Sorry. Giant roly polies?

Ellen: Now, hold on. Were they pill bugs or where they pill millipedes? Pill millipedes are bigger.

Christian: No, these were giant. Bigger than any insects. So this was dramatized of course.

Ellen: Okay. I mean you could have just gone with the grubs in The Lion King, cause I'm pretty sure some of them were roly polies too.

Christian: Also A Bug's Life. Disney's A Bug's Life has two roly polies in there.

Ellen: Oh yeah! Roly polies in there!

Christian: They were acrobats!

Ellen: I forgot about that! Yeah. So I think that roly polies are very culturally important and I feel like people in, at least in our part of the country hold them a very high regard and have very fond memories of them and thoughts of roly polies. I think a lot of people love roly polies but maybe don't know that much about them. So hopefully now you do.

Christian: Yeah.

Ellen: Yeah.

Christian: Well thanks hun.

Ellen: No problem.

Christian: You blew my mind several times in the past 35-ish minutes.

Ellen: I'm glad I could. So before we move on to Christian's animal, I would like to take a really quick minute to mention that we have a Patreon. So if you want to help us grow and get better and better, you can support us on there and also get access to some cool stuff like a feed of the show with no ads in it and a patron discord and all sorts of really cool stuff, so come check us out at patrion.com/justthezooofus and for this week's episode, I want to thank our patrons, Brianna Feinberg, Krystina Sanders, and The Jungle Gym Queen.

Christian: Thanks y'all.

Ellen: Yeah, thank you everybody! All right, Christian, what do you have for us this week?

Christian: This week, I have the keel-billed toucan.

Ellen: Yessss! I love this bird.

Christian: The species was submitted by our friend Kyle Rauch.

Ellen: Thank you Kyle.

Christian: Yes, thank you.

Ellen: You can take it down a notch now.

Christian: So the scientific name for this one is Ramphastos sulfuratus. It also goes by the common name rainbow-billed toucan.

Ellen: Oh, how lovely.

Christian: For obvious reasons, when you see a picture of it. I'm getting my information for the keel-billed toucan from two different websites run by the Cornell Lab of Ornithology, one being Neotropical Birds, found at neotropical.birds.cornell.edu, and also All About Birds, found at allaboutbirds.org. Also from Animal Diversity Web, found at animaldiversity.org.

Ellen: University of Michigan's Museum of Zoology.

Christian: Cool.

Ellen: Yeah!

Christian: So a little bit of some stats about the keel-billed toucan.

Ellen: Yeah. Let me hear these stats.

Christian: The males average about 554 meters- sorry... Yes. 554 meters.

Ellen: WHAT.

Christian: Half a kilometer,

Ellen: This is like the 50-foot-tall quokka! So we've got a 50-foot-tall quokka, a half meter- half kilometer toucan... Fight.

Christian: I'm pretty sure it goes to the letter. Okay. So males average 554 millimeters in length...

Ellen: There we go.

Christian: Or 22 inches, whereas the females average 520 millimeters or 20 inches in length. They weigh around 400 grams, which is 14 ounces. So less than a pound. Their location extends from Southern Mexico to Northwestern Venezuela. So talking about Central America in the very northern part of South America.

Ellen: Very cool.

Christian: Yes. They belong to the taxonomic family Ramphastidae. Uh, their notable evolutionary relatives are other toucans. The family is known as the Neotropical near passerine bird family.

Ellen: Oh, that was a lot of words.

Christian: Yes. I'm gonna dunk right into it with the effectiveness.

Ellen: Yes.

Christian: I'm giving this birb an 8 out of 10 for effectiveness.

Ellen: That's good!

Christian: So it'\s main thing here is, unsurprisingly, it's big bill.

Ellen: Big ol' beak.

Christian: Yes.

Ellen: Big ol' schnoz on him.

Christian: So for those that maybe have never seen a toucan...

Ellen: Have you eaten fruit loops before?

Christian: Have you played the latest generation of Pokemon RPG games?

Ellen: Oh, It's in there too. Lots of toucans.

Christian: Yes. So they're birds that fly, like most birds are prone to doing.

Ellen: We literally just talked about penguins. We JUST talked about penguins.

Christian: Sorry. All the good birds. And they have, so their feathers are mostly black. They have a big banana-shaped bill, takes up the majority of their face real estate. And just so you know, there are several kinds of toucans in this particular toucan has a very colorful beak. I imagine that's why this one was the specific one submitted to us.

Ellen: It's the most fabulous.

Christian: Yes, but more on that later. Talking about effectiveness now. So first of all, they use those big beaks to take the husks off fruits and nuts.

Ellen: What that beak do tho?

Christian: And I keep saying beak, but I think the appropriate term is bill.

Ellen: What that bill do tho?

Christian: I'm sure there's a scientific difference that I do not know. The length of that bill is useful for getting at fruit that is on branches that are too small to support the full weight of the bird.

Ellen: Oh, I see. That makes sense.

Christian: So people have have a couple of different theories about what that bill is and is not used for. A lot of times in the family, something like this would be used for attracting mates. Like in the case of the peacock, where the male peacocks have big showy, you know, tail feathers. But the thing is with the toucan, or at least this species of toucan, there's no real difference between the bills between male and female. So they don't think it's used for attracting mates.

Ellen: I have some ideas about what it's not used for.

Christian: Okay.

Ellen: Kebab skewers.

Christian: Correct.

Ellen: Air traffic signaling.

Christian: Yes.

Ellen: That's as far as I got.

Christian: Okay.

Ellen: Do you have any?

Christian: I mean I know. I'm kind of at an advantage here.

Ellen: Of things it's not used for?

Christian: Laparoscopic surgery.

Ellen: Thank you. Was that so hard?

Christian: Now what's really interesting about the bill is one recent proposal on one of its uses comes from allaboutbirds.org, so one idea is that maybe it's used as a heat sink. So they put a toucan in front of a infrared camera and could see the dispersal of heat in the toucan, and they saw that the bill is significantly hotter than the rest of the bird.

Ellen: Oh really?

Christian: So the thought is it's doing the same kind of thing that the ears are used for in elephants.

Ellen: You know, that makes sense.

Christian: Yeah. So they'll disperse heat into that extremity, and then it's used as a heat sink like in a computer. And then that heat is transferred to the air.

Ellen: You said a heat sink like in a computer?

Christian: Yes.

Ellen: That's over my head. I don't know what you're talking about.

Christian: So for those unfamiliar, lots of CPUs- the main thing in your computer- it's the CPU chip, and then on top of that sits a heat sink. Think of it as a series of metal plates that sit on top of your CPU. And then on top of that is a fan. Usually.

Ellen: I know about that part.

Christian: Yes. So the fan is moving air over those metal plates, and those metal plates are in contact with that CPU. So the heat transfers from the CPU into the heat sink, which has a ton more surface area than the CPU itself. So with all that surface area, it's able to disperse that heat better than the CPU itself.

Ellen: Like a toucan's bill.

Christian: Yes! A toucan's bill is big, right?

Ellen: It has the more surface area.

Christian: It's almost a third of its entire length.

Ellen: That actually makes sense.

Christian: Right.

Ellen: I wasn't expecting a computer science lesson.

Christian: Right? And then finally, another thing they use that big bill for is when they have arguments over who gets to use a tree for nesting.

Ellen: I love that.

Christian: So they either use natural or woodpecker-made holes in trees to nest. They don't normally roost in those, but they will nest in those.

Ellen: Okay.

Christian: And when there's a clash over who gets the tree, they, they smack their bills against each other.

Ellen: That's so funny.

Christian: It's very lightweight. Cause you know, they still have to fly.

Ellen: Yeah.

Christian: So I imagine it's an interesting sound that that would make. They swallow pitted fruits whole.

Ellen: Pitted fruits meaning like...

Christian: An example would be a peach. But not a peach. Cause they don't have peaches.

Ellen: They swallow it whole, what do they do with pit?

Christian: Can you guess?

Ellen: Ooh, fun game! Do they just digest it?

Christian: So, two things happen, and it depends on the size.

Ellen: Whatever you're about to tell me is gonna just destroy me.

Christian: No, no, no, no. So one, I think a lot of people can guess: if it's small enough, it just passes through their digestive track.

Ellen: Sure.

Christian: They poop it out.

Ellen: No big deal.

Christian: Right. And that helps with dispersing seeds and stuff and et cetera.

Ellen: That's exactly what the plant wants them to do.

Christian: Yes. The other option: also dispersal, but it's different. So if it's too big, what it'll do is after it's done digesting all the fruit flesh from around the pit, it just regurgitates the pit.

Ellen: Oh, blech. Nope, don't need this.

Christian: Yep. And neither of those things hurt the bird.

Ellen: Oh it's gotta be, you gotta have a pretty tough kind of digestive system then.

Christian: And probably a very good judge of the size of things that it's eating. Cause if it hurts going down, it's probably gonna hurt coming out.

Ellen: Gross.

Christian: Either way.

Ellen: I've seen really cool videos of toucans throwing their food up and like, catching it out of the air.

Christian: Yep. That's kind of how they eat. They'll pick things up with the, the end of their bills and then just kind of flip their head back and swallow it. So that's what they're doing. They're swallowing.

Ellen: It's so cuuute. It's so cute! That makes sense. I mean they can't...

Christian: It's how I take pills.

Ellen: They can't exactly chew things.

Christian: And while they eat mostly fruit, it also sometimes eats eggs and hatchlings of other birds along with small lizards, snakes and beetles.

Ellen: Oh...

Christian: Mostly fruit. But it gets a little bit of protein from animal sources.

Ellen: Mostly fruit, but also, smidge of infanticide. You've got to keep the diet varied.

Christian: So that's effectiveness. 8 Out of 10.

Ellen: Okay. Good bird.

Christian: Ingenuity: 7 out of 10. So when they're nesting, they tend to come back to the same tree.

Ellen: Oh, okay.

Christian: I thought that was interesting, to have that, enough mental capacity to remember where the tree was.

Ellen: It's home base.

Christian: Here's something they do with those regurgitated fruit pits: they use them to make nests.

Ellen: Whaaat! Really!

Christian: Yes.

Ellen: This is like penguins with their pebbles.

Christian: So to quote Neotropical Birds, the article I was using: "as a result, the young are reared in a nest with a cobblestone lining of fruit pits the size of large marbles."

Ellen: Whaaat! That's crazy!

Christian: Right?

Ellen: That's awesome. Like they don't necessarily need to go gather all of the nest materials. They can just make some. That's so cool! What an interesting like... Resourcefulness kind of.

Christian: Yeah. I'm sure the seeds aren't happy because that's not what they wanted to do.

Ellen: Hey, wait a minute...

Christian: I'm a wall.

Ellen: I didn't want this at all.

Christian: This is like that movie 300. Oh, here's my favorite little thing about their ingenuity. I wasn't sure if I should count this as ingenuity, but I am.

Ellen: Sure.

Christian: They're known together in small groups of 6 to 22 individuals...

Ellen: That's a lot.

Christian: And they chase each other from branch to branch playing ball.

Ellen: No, they don't. Stop it.

Christian: One bird throws a fruit in the air and another one catches it.

Ellen: NO.

Christian: Yes.

Ellen: They do this by themselves?!

Christian: In groups of like 6 to 22, yeah.

Ellen: I mean like, I mean like they do this in the wild.

Christian: Yeah.

Ellen: What! That's the cutest thing I've ever heard!

Ellen: Right?

Ellen: I love it.

Christian: So I thought that was pretty smart. You don't really see animals that play a lot.

Ellen: I feel like engaging in play is a sign of some real cognitive activity. Right? Like doing things for pleasure instead of just because you need to do them to not die.

Christian: Yeah. Basically.

Ellen: Man. How charming is that?

Christian: Right? That's my favorite part.

Ellen: Yeah.

Christian: On to the last: aesthetics. Full 10 out of 10.

Ellen: Yes, absolutely.

Christian: I feel like any less than I would have been burned at the stake by our listeners. Specifically Kyle.

Ellen: And also me, your wife who's sitting right next to you and you're well within stabbing range.

Christian: I'm just kidding. I agree with this score. First and foremost, pretty colors. And the colors are both on their bill and their body in general. So the colors for their body, mostly black, but also with yellow, red, white and blue because their skin is blue. So you'll notice that their feet are blue, and then the area around their eyes don't have feathers. Like the, like a very small area around their eyes don't have feathers, but their skin is blue so it adds a little blue accent in there.

Ellen: I don't think I ever really realized that their skin was blue. For a really long time, so way, way, way back in high school I did an art portfolio and one of the things I did for my art portfolio was a painting of a toucan.

Christian: Oh yeah?

Ellen: And it was a keel-billed toucan, it was the one you're talking about.

Christian: Oh, cool.

Ellen: So I actually do kind of remember having to make the feathers black, but also blue because they have that sort of sheen to them. Kind of like when we talked about the ravens, how they're black, but in the right light they also look blue.

Christian: Sure.

Ellen: But for a while toucans are kind of my go-to. Like if I was just bored and I wanted to doodle something I'd usually draw a toucan, and then also they became kind of my, like, if I got new art supplies and I wanted to test them out, I would usually test them with the toucan because it's a really good way to test out all of your colors. But it's also a good way to test out your tonals and seeing how like faithful your shades of black are.

Christian: That's cool, that's cool. So you especially know this, so they primarily have black feathers and then the part of their feathers that are, like their neck, what we would describe as their neck and the upper breast are yellow and then on their underside towards the tail they kind of have a splash of red feathers and white feathers.

Ellen: I like that they kind of look like they have like a bib. It's like a little bib.

Christian: Yeah. So that's just their body feathers, cause then there's the bill. So the bill is a huge splash of color.

Ellen: It just pops off.

Christian: Yeah. Which is where they get their name. Green, red, orange and blue. All of those colors in there.

Ellen: Got everything.

Christian: Yeah.

Ellen: This is like, there's that concept in fashion where like, if you're gonna wear a big bold statement accessory, you should pair it with a subtle and understated outfit. They've got like the plain all-black, but then they've paired it with like this bright flashy beak.

Christian: Yeah, yeah. It's very good.

Ellen: It's very aesthetically successful.

Christian: Yep. And other toucans out there will have a similar color, but their beak is primarily just red and orangeish colors without all those bright accents in there.

Ellen: They're so cute.

Christian: Yep.

Ellen: So pretty.

Christian: So speaking of which, my next point for aesthetics was, you know, cute face. I think their faces are cute.

Ellen: They are! It's all nose.

Christian: And the eyes are cute too. I like their curvy shape. I just like the curve of their silhouette of like their overall...

Ellen: It does give them kind of an S shape almost. You know what I mean?

Ellen: Yeah, yeah.

Ellen: Like it sticks out. So it kind of gives them almost an S shape to their body.

Christian: I just had a weird thought of like a scythe, that was actually a toucan. OC do not steal.

Ellen: I was about to say, like, you might encounter this in your next D&D campaign that I'm DMing for you.

Christian: Toucan't possibly win against me.

Ellen: That would work really well against an adventuring party of two people.

Christian: Yes. Uh, final aesthetics point: their toes. Their toes are arranged in what's called the zygodactyl pattern, which means two forward and two back.

Ellen: Very nice.

Christian: Yes. So this is common in arboreal birds, or birds that would be doing a lot of walking through tree canopies. Toucans primarily do that. They walk and hop along branches. They do fly, but that's not for super long distances. It's like it's like to cross a river or a valley or something like that.

Ellen: From tree to tree.

Christian: Yeah.

Ellen: I mean, they're living in very densely forested areas so they don't really have to fly for very long distances.

Christian: And they're not migratory or anything, either. A couple of little miscellaneous items about the toucan. So, first and foremost, they are rated the least concern on the IUCN Red List.

Ellen: Oh, phew.

Christian: Which is surprising, right? Something that exotic you would think maybe might be in danger.

Ellen: They're also very popular though.

Christian: Yes. So while they are at least concern, their population is on the decline, mostly due to habitat loss. But still of least concern. Primarily because they just have a huge population in that area. There used to be a problem with the illegal pet trade, but since then there are very experienced, I suppose- the industry where they raise these birds in captivity now and breed them in captivity, so there's no reason to take them out of the wild.

Ellen: Sure.

Christian: That being said, they are very popular and very expensive pets. Couple thousand dollars, from what I understand.

Ellen: Are they legal to have as pets?

Christian: I don't know, honestly.

Ellen: Oh. Okay.

Christian: I'm sure. Like...

Ellen: It's just an exotic bird, right?

Christian: Yeah. If, I mean getting through the proper channels, I'm sure. You can't just go take one out of the wild though, I'm sure.

Ellen: Now, legality of keeping a pet and morality of keeping a pet are very different things.

Christian: Very true.

Ellen: There are a lot of animals that it is totally legal to have them as your pet, but don't do it though.

Christian: So funny thing, a lot of places in their native habitat, will just allow them to be out and about. Like they can come and go as they please in the houses.

Ellen: Oh, I like that! I would definitely invite one into my house. If they lived here, I would keep my windows open all the time.

Christian: They are in monogamous pairs when when they breed.

Ellen: Oh! So sweet. Is this like serial monogamy like we talked about with the penguin where it's like one partner at a time?

Christian: You know, I was trying to look for that specification because of, you know what you were saying about penguins. I couldn't find anything more specific than just saying monogamous pairs.

Ellen: Okay. If you are out there listening and you study toucans and you know about their mating habits, please follow up with us and we will include your expertise.

Christian: Yes. Oh, while I was doing this research, I learned a new word: altricial.

Ellen: Altricial.

Christian: Yes. So this describes something that is hatched or born in an undeveloped state, and requires care and feeding by the parents.

Ellen: A baby.

Ellen: Yeah. So a toucan is one of them. Humans are another. So the opposite of altricial is precocial.

Ellen: Precocial. Okay. Like a precocious youngster.

Ellen: Yes. Actually the same root. An example of this are horses.

Ellen: Oh yeah, yeah, yeah. How they're born walking. Okay, that makes sense.

Christian: And finally, the toucan is the national bird of Belize, which is a country in Central America, it shares a border to the North with Mexico.

Ellen: Very cool. Awesome. I hope that someday we get to see some. We've seen some in zoos, I think.

Christian: I think so too, but maybe not this specific species.

Ellen: We have seen toucans in zoos, but they were not specifically the keel-billed toucan. But I would really like to see some in the wild someday, so whenever we make our way down to Central or South America, I'm sure we'll see some, we'll have to make a point to visit.

Christian: Yeah. That's all I have.

Ellen: All right. I don't have any audience responses either, so I guess we're just blowing through this one. It's okay cause we talked for a really long time.

Christian: We had some good animals.

Ellen: Yeah, we were content only this episode.

Christian: Definitely no goofs, not at the beginning.

Ellen: This is strictly serious. We are factual information only. We do not goof around here.

Christian: Mhmm. No goofs.

Ellen: No goofs allowed. This is a no-goof zone. Alright, well that wraps things up for us on this week's Just the Zoo of Us. Thank you so much for joining us. Thank you for everybody who's been listening, thank you to everybody who's been recommending us to your friends and family and coworkers and hairdressers and dentists and lawyers.

Christian: That person you met on the street yesterday.

Ellen: Yeah.

Christian: Should probably follow up with that person.

Ellen: Yeah. Actually make sure you give them your personal phone number. Thank you also to everybody who has been hanging out with us in our Facebook group. We love y'all. Y'all are the best, and everybody in our sort of social media circles. You can connect with us on Facebook, Twitter, or Instagram by searching the title of the show. That'll get you right to us. If you have an animal species that you want to hear us review, you can get those to me at Ellen@justthezooofus.com, and for our last note, we would like to thank Louie Zong for allowing us to use his song "Adventuring" from his album, Bee Sides.

Ellen: Yes. Thank you so much.

Christian: We love it. You want to hear it?

Christian: Yeah.

Ellen: Alright, here it is.

Christian: Bye y'all.

Ellen: Bye!

22: Mata Mata & Emperor Penguin

Ellen: Hey there! This is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And this is Just the Zoo of Us, your favorite animal review podcast where we take your favorite species of animals, we review them and we rate them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: You know, we say favorite animals, but I don't think anyone would call the botfly their favorite. Except me.

Ellen: That was also not requested by anybody. That was just you being vindictive. Anyway, we take your requests for species of animals and we review them comprehensively and rate them out of 10 in different categories. We are not zoological experts, but we do a lot of research to get ready for the show and we make sure that we're getting our information from trustworthy and reliable sources. So if you are a zoological expert, feel free to link up with us and let us know your thoughts and give us feedback and such. We're very thrilled to hear from people all the time.

Christian: Yeah, reach out to us, you reliable source, you.

Ellen: Yeah, thanks. We really appreciate it. That sounded sarcastic, but it wasn't meant to be, I promise. That's all I got for the intro, and I think that last week I went first. So Christian, it's your turn.

Christian: Okay. This week, I've got an animal that I think has a fun name, called the matamata turtle. Couple of different, not really spellings, but I guess arrangement of that name. You'll see matamata as one word, you'll see them separated by a hyphen, and sometimes by a space.

Ellen: Oh, sure.

Christian: And sometimes they won't even say turtle, they'll just say matamata. So...

Ellen: But it is a turtle, though?

Christian: It is a turtle. It is defo turt.

Ellen: Certified turt. Turtified.

Christian: The scientific name for this little guy, maybe not little, but the scientific name is Chelus fimbriata, and this species was submitted by Erica Carr and Miranda Lowrey.

Ellen: Thanks, y'all.

Christian: Thank you. And my information for this one is coming from some familiar sources: The Smithsonian's National Zoo and Conservation Biology Institute, the website is found at nationalzoo.si.edu.

Ellen: Nice.

Christian: And also from Animal Diversity Web, found at animaldiversity.org.

Ellen: Love them.

Christian: Yes. Let's talk about the matamata generally. So these guys can grow up to almost 45 centimeters long based on their shell. I'm not sure why, but all of the lengths that I found for the matamata was all based on the shell size. I'm not really sure why that is. Maybe that's just common in turtles.

Ellen: I guess it's probably because like, they can retract into their shell.

Christian: Well, and here's the thing. Most turtles, that would represent the majority of their length, whereas the matamata has a fairly long neck.

Ellen: Oh...

Christian: Yeah. So anyway, up to 45 centimeters long, which was about a foot and a half, and they can weigh 17.2 kilograms or 38 pounds.

Ellen: That's a chunky boy.

Christian: Yeah.

Ellen: Hefty turtle.

Christian: Where these guys can be found is in the Amazon and Northern South America, including Venezuela, Brazil, Peru, Ecuador, Colombia and Bolivia, and also the Island of Trinidad.

Ellen: Oh wow! That's cool.

Christian: Yeah. They belong to the taxonomic family Chelidae, these guys are known as the Austro-South American side-neck turtles, as in Australia.

Ellen: Oh, okay.

Christian: And what side-neck means is they bend their necks to the side when pulling them under the edge of their shell or carapace, rather than retracting it directly inward.

Ellen: Oh, okay. So they're coming at it from an angle.

Christian: Yeah. So these guys, they have a, of course a turtle shell, and these are primarily aquatic turtles. So this kind of gives you an idea of what they kind of look like. They have shells with big ridges. They remind me of Bowser, personally.

Ellen: Like, they're spiky?

Christian: Yeah, yeah.

Ellen: Okay, okay.

Christian: And they have webbed feet with claws, all four feet are webbed. They have that long neck that I mentioned earlier, and then that neck has fringes and like, almost wart-type things coming off of it. Their head is triangular, and they have a thin tube coming off of their nose, and small eyes and a big wide mouth. If you look at them from head on, it kind of looks like they're smiling.

Ellen: Okay!

Christian: And often with this kind of turtle you'll see them with moss growing on their shell and body in general. So that's kind of just to set the picture going forward.

Ellen: This is painting a really bizarre zoological picture for me. I'm imagining something very strange.

Christian: Yeah, yeah. Effectiveness, this is how good they do the things they do. Physical adaptations, built-in lasers. No, I'm just kidding. So for the matamata, I'm giving an 8 out of 10 for effectiveness, and some of the big points here are around camouflage. So the way the neck is, and the head, it is meant to look like foliage, like at the bottom of a body of water.

Ellen: That makes sense.

Christian: And also the tendency for moss to grow on the shell helps with this. Also, how they eat. Did not know this at all before researching the matamata, not that I was an expert in it to begin with.

Ellen: Yeah, I know nothing, so whatever you're about to tell me is going to be surprising to me.

Christian: Um, so out of curiosity, how would you guess that these, these things eat?

Ellen: With their mouth.

Christian: I guess you can assume they're, what, carnivores or plant eaters or?

Ellen: Um, let me think... Okay. You said it has a tube.... It has like a, like a narrow tapered mouth in some way?

Christian: Well, its nose has a thin tube.

Ellen: Okay...

Christian: But its mouth is big and wide.

Ellen: And a wide mouth. Hmm. I guess I would assume that they would maybe eat small fish?

Christian: Yeah, you're right.

Ellen: Oh, great!

Christian: So here's how they do it, though. They don't just go and chomp down on a fish in the water. What they do is they use this pretty unique method of capturing fish. So its bite is actually pretty weak, but what it does is, with is neck fully extended and there's a fish nearby, what it does is it- when the fish is close to its mouth, it quickly opens its mouth and it expands its neck...

Ellen: What.

Christian: To cause a sudden low pressure that sucks in the fish, and then they swallow it whole.

Ellen: This- so, I'm thinking of it as like the hose attachment of a vacuum cleaner.

Christian: Basically. Um, but it's crazy and I encourage everyone to go look at a YouTube video of this, but its neck expands in terms of diameter, to just basically suck in the water and the fish.

Ellen: So when I talked about the axolotl, I talked about how it has that really big wide mouth and it would suck prey in by opening its mouth very quickly.

Christian: Yes, it's that, but also not just opening its mouth quickly, it's also expanding its neck. So kind of compounding that effect.

Ellen: Oh, I see.

Christian: So think of it as having bellows underwater, and as you pull it open, it's causing a low pressure to suck in water. So that's what's happening.

Ellen: Wow. That's crazy.

Christian: Yeah.

Ellen: Huh. I guess that explains why its neck is so long, then. To just give it space.

Christian: It just, "wah," like inflates. So, yeah it's crazy. So they suck in the fish and let the excess water escape as things start to kind of close back up, and then they'll swallow the fish whole.

Ellen: Does the water escape back out through the mouth?

Christian: Yeah, it kinda like, half closes its mouth basically to let the water escape.

Ellen: Huh.

Christian: Yeah.

Ellen: Does it have any method to, I guess, separate the fish that it's trying to eat from anything else that may have gotten in there, like rocks or something?

Christian: I mean, I assume this is kind of a common problem for most reptiles underwater.

Ellen: Sure.

Christian: But it makes do, it just eats them whole. Alive.

Ellen: You take the good with the bad, I guess. Okay, so it eats the fish alive. It doesn't chew them or anything.

Christian: Yup.

Ellen: Huh. That's brutal.

Christian: Right? And the next point I want to give it was its nose, and I actually refer to it as a snorkel nose. Cause what it's meant to do is it just- so this turtle almost is always underwater, and it uses that snorkel nose just to expose the bare minimum of itself above the surface of the water to breathe. Now here's what's strange, a little bit about this guy that is under the water all the time: it has very poor eyesight.

Ellen: Oh...

Christian: Yeah. But it makes up for it. The fringes and whatnot on it's neck allows it to sense vibrations in the water very, very well.

Ellen: I would imagine it's in very murky water, so it's probably not going to get much through vision anyway.

Christian: True.

Ellen: Like even if it did have good eyesight, it probably wouldn't really be seeing much.

Christian: True, because these things are found in slow-moving or stagnant water that's not very deep.

Ellen: Probably a lot of sediment in the water and stuff. So it makes sense that they would be more interested in using feelers. So like, the electric eel used the electricity to sense its environment, so when you are living in a low visibility area, it makes sense for you to kind of find other ways to perceive your world.

Christian: So yeah, the way it does that is through vibrations and also having very good... I say ears, but they're not really ears in turtles. They work a little differently. But same concept though, it can hear sounds very, very well.

Ellen: Oh, okay.

Christian: The main deduction I have for effectiveness is they actually aren't very good swimmers.

Ellen: Oh- what! That's the one thing you gotta do though!

Christian: So they're actually, they're not very good at swimming, but they're better equipped to walk on the muddy beds in the shallow water, rather than swimming in the open water.

Ellen: I mean, I guess, but if you gotta live in the water!

Christian: It can make do, it's just, it's not very good at it.

Ellen: Aw, man.

Christian: Which makes, I guess it kind of makes sense cause it's kinda hanging out on the bottom, waiting for fish to come to it. Right? Cause it's not actively hunting fish.

Ellen: Yeah. But they still like, they have to come up to the surface to breathe, and...

Christian: I think that's why they like shallow water, because it's not a big distance between the bottom and the surface.

Ellen: I mean, I guess they need it to be that way cause they're not good swimmers.

Christian: Well they could do it. It's just not graceful at all. So yeah, effectiveness, 8 out of 10. Ingenuity, so this is how they do smart things. Examples of this could be tool use or interesting methodologies. I'm giving a 6 out of 10. I found its feeding method to be interesting, of course, so kind of going back to that, but also,, it's use of camouflage. I think that's interesting. But otherwise, not anything else, particularly...

Ellen: Just beneficial behaviors, but they're not necessarily figuring anything out.

Christian: Yeah. Yeah. I did read somewhere though that they've been studied to, I guess, move fish into a more restrictive area before sucking them up.

Ellen: You mean, like herding them somewhere?

Christian: Yeah. Yeah. I couldn't find very much info about that though.

Ellen: That's something to keep in the back of the head.

Christian: Yeah. So 6 out of 10 for ingenuity.

Ellen: It's not bad.

Christian: Aesthetics: I'm giving this one a 7 out of 10.

Ellen: Really?

Christian: Yeah.

Ellen: ...Really?

Christian: I think they look interesting.

Ellen: Interesting, yes. Good, though?

Christian: I think they're interesting. The combination of their spiky shell and the triangular head with a long neck, you know, with all the frills and the moss. I think it's an interesting look.

Ellen: What I'm thinking of, I know there's a Pokémon based on this turtle.

Christian: Yes, there is.

Ellen: What is it called?

Christian: I don't know.

Ellen: Hold on...

Christian: It's one of the generations I didn't play. It's the fire turtle, I think?

Ellen: Yeah... You did play, cause this was in sun and moon.

Christian: Oh. See, that's the problem with having skipped some generations. I don't always know what is new and what was already there.

Ellen: Oh my God. You're going to love what it's called.

Christian: What is it?

Ellen: I just Googled it. Turtonator.

Christian: Haha! K.

Ellen: I forgot all about this Pokémon because it was in Sun and Moon, I believe, which I played, but I didn't play a lot of, and I think it's kind of, I think it's ugly. I'm sorry. I think it's really ugly.

Christian: Well, I think the actual matamata looks much cooler than that.

Ellen: Well, so we have seen a matamata. We saw one, I believe at the Atlanta Zoo? I think they had one in there. And I think we only like barely saw it, but I found it, um, kind of ugly.

Christian: There could be variations, in terms of color.

Ellen: Yeah. Okay. I'm looking at a picture of it right now. And interesting is... a correct descriptor of the way it looks. Interesting is a word you could use to describe it.

Christian: Well, it's all arbitrary. So...

Ellen: I know.

Christian: 7 out of 10.

Ellen: I know. That's- and that's you, that's a you thing.

Christian: That's it for my scores. Some more miscellaneous info: its conservation status is not evaluated on the IUCN Red List. It is popular in the exotic and illegal pet trade.

Ellen: Oh wow.

Christian: Yes.

Ellen: So people have these.

Christian: Mhmm.

Ellen: ...Why though?

Christian: Because of their uniqueness, I suppose.

Ellen: I mean, I guess.

Christian: I also read that at one point they were popular as a food item.

Ellen: Oh. Gross.

Christian: But that kind of died down as they found other turtles more suitable to being food, and also more aesthetically pleasing, I guess.

Ellen: Yeah. I feel like I wouldn't look at one of these and be like, mm, tasty. Good eats there.

Christian: Right?

Ellen: Gross.

Christian: So these guys, they can live up to 15 years in captivity. Their longevity in the wild has not been studied. And finally, their name, "matamata," is said to mean I kill in one of the South American native languages.

Ellen: Oh... I mean, yeah, it does do that. Sure. You know, I feel like when you look at them, they look a little bit more intimidating than I suppose they really are.

Christian: Yeah. I mean if you are a fish that could fit in its throat, definitely. But anything else, you're fine.

Ellen: Yeah. They look like, with how like spiky and jaggedy they look, they look like they might be able to do some damage to you. I feel like they look like a snapping turtle.

Christian: They do kind of, but again, their bites are really weak and that's not where they shine.

Ellen: Yeah. It's just, maybe that's a sort of mimicry where they want to look really tough and intimidating, but they're actually not.

Christian: So that's the matamata.

Ellen: That's a good turtle.

Christian: Yeah.

Ellen: Good job! Well, before I get started on my animal, I want to take a quick a moment to thank our patrons on Patreon. We have a Patreon where you can get access to cool things like an ad-free version of the show, you can skip the commercials. We also have cool stuff like a patron-only discord server and we're going to be sending out really cool things like some photo prints of some animal photos that I've taken, so all sorts of cool stuff on the Patreon. For this week's episode, I want to thank our current sponsors, Briana Feinberg and Krystina Sanders. Thanks y'all.

Christian: Thank you.

Ellen: Yeah.

Christian: Okay. Ellen, what animal do you have for us this week?

Ellen: This week, I'm talking about a very popular animal that I think a lot of people are going to be excited to hear about: the emperor penguin.

Christian: Ah yes! Very good.

Ellen: Yes. This was requested by Taylor Gordon-Wood, who by the way did our cover art that you see everywhere that we exist. That really cute illustration with all the little animals on it and our cool logo, that was all Taylor. Thank you Taylor. So Taylor wanted to hear about the emperor penguin.

Christian: Alright.

Ellen: The scientific name for the emperor penguin is Aptenodytes forsteri, I completely made that pronunciation up, so don't @ me. I'm getting the information for the emperor penguin from the Australian Antarctic Division of the Australian government's Department of the Environment and Energy, and also the Smithsonian Institute. So to introduce you to the emperor penguin, this is the largest species of penguin. They're typically around four feet tall, or 1.2 meters.

Christian: That's pretty tall.

Ellen: Yes, this is a big penguin. And they are up to 40 kilograms, or 88 pounds.

Christian: Woah.

Ellen: Yes, heavier than most other birds. Usually when you hear of a bird, they could be that big, but they might only be like 20 pounds. Right? Because of how light they are? The penguin is much, much heavier than other birds, and I'm actually gonna talk about that in a minute here.

Christian: Okay.

Ellen: You find these in Antarctica, which by the way is the South pole, not the North pole. A lot of times you'll see people making jokes about like Alaska or the Northern parts of Canada or Russia, like talking about there being penguins up there. They're not. They're on the other side of the world. Sorry.

Christian: They got polar bears, though.

Ellen: Polar bears, yes. But so also, a lot of times people joke about like penguins being eaten by polar bears or something. They live on complete opposite ends of the entire earth. So they don't live there.

Christian: I bet they would if they met, but...

Ellen: Yes, I'm sure a polar bear would not hesitate to eat a penguin- although, maybe it wouldn't. Maybe it would be like, "I don't know what that is" and leave it alone. Sometimes predators will do that. Sometimes predators will be like, "I don't, I don't know what I'm looking at" and they won't eat it.

Christian: This isn't chicken nuggets. I'm not eating that.

Ellen: Yeah, polar bears are a lot like my five year old that way. But so anyway, there are at least 17 different species of penguins. You'll see different numbers for the number of penguin species because some subspecies classifications are in question. So some places will consider different subspecies of the same species or some consider them their own thing, but at least 17 different distinct species of penguins.

Christian: Awesome.

Ellen: Yeah, the emperor penguin is one of two species in their genus that is known as great penguins. So the great penguins are the big boys. They're the emperor penguins and then the king penguins, which are very, very similar to emperor penguins, but they're much smaller. So the king penguin, therefore, is their closest relative, but there are many other different types of penguins. That's just kind of your primer on the emperor penguin. I'm going to get started with effectiveness as Christian did. For effectiveness. I give the emperor penguin an 8 out of 10.

Christian: Alright.

Ellen: So I want you to think of two primary goals that they have in mind. First of all being survival, and second of all being feeding. So living in Antarctica, the emperor penguin is naturally highly adapted to face really, really harsh conditions. So very, very low temperatures, very violent winds. They're kind of made for this. Look at how far they are removed from other birds. Their wings are adapted to function more like flippers than like traditional wings. So I saw something recently like, floating around on Twitter that says like a penguin might seem like a terribly made bird if you're thinking of it in terms of other birds, if you think of its wings more as flippers, they don't seem so bad.

Christian: Right.

Ellen: First of all, I want to talk about their feathers. A lot of people think that the penguins stay insulated from the cold by having dense feathers, by having lots and lots of feathers on their skin and just like the density of their feathers is what protects them. That's not how it is. That's not true. That's not how they work. There have been more recent studies in 2015 showing that it's not the case that their feathers are dense, it's just how many different types of feathers they have on their bodies. So their feathers are actually layered in different types. So there was a study by Cassondra Williams, Julie Hagelin and Gerald Kooyman published by the Royal Society on October 22nd of 2015 basically saying that penguins keep warm not by having a lot of feathers, but by having complex layers of different types of feathers. The outermost layer are contour feathers, these are similar to what we think of as flight feathers on other birds. These are the long, stiff feathers and these keep the penguin's body streamlined so it reduces drag in the water and also keep an outer sort of layer to keep cold water and keep cold temperatures out. Now when penguins preen, you see them using their beak to preen their feathers, what they're doing is they gather a hydrophobic oil that is actually produced by a gland on their body near their tail. This gland produces an oil that they gather up with their beak and then when they preen they spread that oil over their feathers, and it makes their feathers hydrophobic.

Christian: Neat!

Ellen: Yeah. So you can actually see, if you take a penguin feather, you can like drop water on it and the water just slides right off.

Christian: Nice.

Ellen: Yeah. So it's really, really good for when they dive down into the water to eat the fish to catch fish that they're trying to eat. It keeps the water from seeping in and making it to their skin. And also, that hydrophobic oil prevents their feathers from gathering ice.

Christian: Ah, that's important.

Ellen: Yeah, it's really, really important to not, you know, collect ice on your feathers and the hydrophobic oil keeps that from happening. Underneath the contour feathers are two different types of feathers. These are two different types of soft downy feathers. So there's afterfeathers, which are attached directly to the contour feathers, and then there's these things called plumules, which are actually attached to the skin. They're not connected to the contour feathers. So both of these are soft downy feathers, and the purpose of those is to trap air underneath the contour feathers and insulate the body and trap the warmth to keep the cold from permeating to the skin.

Christian: Okay.

Ellen: So those are the afterfeathers and the plumules. And then there's also these other types of feathers called filoplumes.

Christian: Ooh!

Ellen: Yeah. So these are really, really tiny, tiny, tiny little skinny feathers. You almost need a microscope to see them. They're so, so, so small. And the purpose of these is actually sensory. So these feathers let the bird know if a feather is dislodged or like maybe it's gotten out of place and it needs to be fixed or preened, or they're basically saying, Hey, you need to check on this feather and make sure it's okay. Yeah, so it kind of is a sensor. It's like a little check engine light. Like, hey, check on this feather. It needs some needs, some rearranging.

Christian: That's pretty cool.

Ellen: Yeah, it's really cool! So basically people didn't know that there was so much going on with penguin feathers until very, very recently. So I kind of read the whole thing and thought it was really interesting, that they have all these crazy different types of feathers that basically all work together to make sure that the penguin stays dry and warm.

Christian: That's awesome.

Ellen: Yeah. So the next thing I want to talk about other than their feathers is their bones. Since penguins don't fly, they don't have to worry about having those hollow, lightweight bones that other birds do.

Christian: Right.

Ellen: Right, so other birds have bones that are full of these air bubbles that keeps them light enough to fly. Penguins don't fly, so they don't have to worry about that. So compared to other birds, their bones are solid and dense. This serves a few different purposes. First of all, it allows them to develop really, really strong chest and shoulder muscles. They need much stronger chest and shoulder muscles than other birds because they have to generate thrust in the water, and the water is much thicker than air, so they have to push a lot harder.

Christian: Makes sense.

Ellen: Yeah. So they have just really, really thick muscles there. But another purpose of the solid bones is that it helps protect them from the effects of barotrauma, which we talked about in the blobfish episode.

Christian: That's right.

Ellen: In the blobfish episode, we talked about baro trauma being the negative effects that the change in pressure can have when you dive down into the water where the pressure is very high, and then you come back up where the pressure is very, very low. So penguins also have to dive down really deep in the water to catch fish, to hunt, to do all that stuff that they need to do, they have to dive down. So having thicker, more solid bones helps prevent them from developing barotrauma when they come back up.

Christian: Interesting.

Ellen: Yeah, so few different purposes, but so it's very lucky that they have those thick bones rather than the hollow bird bones.

Christian: Yeah.

Ellen: So another thing that they have to worry about is heat and energy retention, which they solve by having these fat deposits all over their body. They have just lots and lots and lots of fat built up on their body. You can see this when you look at their body and you see how chunky they are, they're nice and thick. So they have these deposits all over their body as well as on their feet. So their feet actually have fat on them, and that keeps their feet from freezing on the ice.

Christian: Okay.

Ellen: Yeah, so that also lets them store and conserve energy because during the winters they have to go for months at a time without food.

Christian: Right.

Ellen: So they have all of these fat deposits on their body to store energy. They also have really small extremities, like their beacon, their wings, which are really thin, so they don't have to let as much heat away from their body. They don't have to let as much heat flow outward. Just some ways that they store heat in their bodies. The last thing for their effectiveness I want to talk about was their countershading. We talk about this a lot with animals that live in the ocean. They have the white tummy and then the black on their back. And that makes them difficult to spot when you're underneath them and looking up, you see white that blends in with the sky, but when you're above them looking down, you see black that blends in with the ocean.

Christian: Okay.

Ellen: Yeah. So this is a really, really common coloring palette you'll see with animals that do swim a lot on the ocean. So just another thing that penguins have that help keep them safe when they're out swimming around in the water. I did deduct a couple of points for them being very vulnerable with no real method of self-defense. You know, they have like a pointy beak and they have sharp claws, but the claws are made more for gripping on the ice and they don't have a lot of mobility with them, so they can't do anything with them really. So in the water, they're pretty much easy pickings for leopard seals and orca whales. So both of those swim much faster than penguins.

Christian: Right.

Ellen: I mean penguins can get some good speed going, but I mean it's nothing compared to the predators they're up against in the water. So, I took a little bit off there cause they don't really have good ways of defending themselves against their predators.

Christian: Right. You'll see lots of videos of them trying to escape those predators, primarily by just getting on top of ice floats and...

Ellen: Yes, so their kind of best bet there is to hop on top of ice and get on top of land, which they have to get on top of a really large chunk of land to be safe because you know like, orca whales and leopard seals are smart enough to be able to tip the ice and knock the penguins off.

Christian: Well, the seal can also get on top of there too, if it wants to.

Ellen: Yeah. Yeah. So I dunno, I took a couple of points off cause they don't really have a backup plan there.

Christian: Sure.

Ellen: Moving onto their ingenuity, I gave them an 8 out of 10.

Christian: Oh!

Ellen: They are clever birds, mostly in their social interactions. Emperor penguins spend most of most of their time in the water, but they have to breed on the ice during the winter and they have to do it during the winter because that's when the ice is the thickest so that it's strong enough to support the whole colony of penguins, right? They're so heavy and there's so many of them that in order for them to all get on top of the ice without the ice breaking, it has to be during the time of year when the ice is going to be thick enough to hold them, which means that they have to be on the ice out of the water during the harshest part of the year.

Christian: Ah.

Ellen: This is the time when it's coldest. The winds are strongest. It's just really uninviting. They survive this winter by huddling. If you've seen Happy Feet or March of the Penguins, you have- you probably have an idea of what this huddle looks like. It's mostly males. The adult male emperor penguins will huddle together where they sort of overlap each other. They sort of lay on top of each other in this massive- hundreds, even thousands of penguins all huddled together in this giant mass and they're tightly packed together, right?

Christian: Right.

Ellen: They're not just standing near each other, they are fully laying on top of each other. So in this colony that is huddling together, individuals, will actually rotate out of and into the center of the huddle. So they're taking turns on the outside edges of the huddle because that's where the winds are really harsh, that's where the conditions are a lot worse. So they actually take turns warming themselves in the middle, making sure that no penguin has to be on the outside for too long.

Christian: Oh, that's good!

Ellen: Yeah, they will also, if there's like a particularly windy day going on or something, the penguins that are on the sides that are facing the wind, they'll do this really interesting thing where they shuffle along the outside of the huddle around to the opposite side and then the rest of the penguins will follow in single file forming this circular procession around the edge to make sure that no penguin has to be in the brunt of the wind for too long. Yeah, so it kind of spiraling out to make sure that every penguin has a turn in the middle where it's nice and warm.

Christian: Awww.

Ellen: Yeah. It's just really cool, and then when they're in this huddle, they almost move as though they're just one giant penguin. You can see all these videos online of sped up penguin huddles where they all move together in these tiny little steps where they all shuffle forward together at the same time to move the entire huddle. It's really crazy to watch, but they do kind of form this hivemind penguin.

Christian: Sure.

Ellen: It's like, we are one penguin

Christian: Now, this is also in a part of the globe where when you're close enough to the poles and it's the winter for that hemisphere, you might be in an area that won't see the sun for a long time.

Ellen: Oh gosh, yeah. Typically in these huddles, what you're seeing are the adult males, and the adult males are in this huddle because they have been left behind by the females. The females have met up with them when the breeding season was starting, which is typically the end of the autumn season leading into the winter. The females will meet up with them, they will mate, the female will lay her egg, she will give it to the male, and then when winter starts to really get rough, the females peace out and they leave. The males stay behind in their huddle with the egg. The male is holding onto the egg, he's holding it in a little what's called a brood pouch, which is a little flap of skin he's got underneath his tummy.

Christian: Aw.

Ellen: He puts the egg under there, so he's holding onto it with his feet and he's got his belly kind of on top of the egg, keeping it warm. The females leave and they leave for months at a time and they go back to the ocean and they feed, so they're hunting and eating. They fill their tummies up and then the males stay behind in the huddle to brave the storm. They have to stay there, right, because the egg is not going to survive in that winter. They can't do anything else with it. They can't leave it at a nest because it's going to freeze. So they have to stay there and wait.

Christian: Protect it with their dad bod.

Ellen: And protect it with their ultimate dad bod that is specifically made for protecting their babies. So they stay there for months at a time. They can't eat anything this whole time, and we're talking like two or three months at a time where they just cannot eat anything. They have to just sit there and wait. So during that time they're just warming the egg, trying to stay alive, and then after a few months the female comes home, mommy comes home, she's got a belly full of food and if by then the chick has hatched, then she will take the chick back from the dad and she'll feed it and the dad will leave and go eat his food. If she comes back and the egg hasn't hatched yet, then she'll just take the egg and the dad will go get something to eat. So they'll trade off like that. The dad will give the baby to the mom, he'll go eat. But then he comes back and they keep doing that. They keep trading off so that one of them can go eat and then come back. So they're both still raising the chick, which is really cool. You're seeing like both parents kind of taking on an equal role in raising the baby.

Christian: Soooo what happens when one doesn't come back?

Ellen: That happens. Sometimes one of them, like either the mom doesn't come back or the dad doesn't come back, and if it is that sort of situation where maybe the mom or the dad has been killed, maybe they've been eaten by a whale or maybe they've just decided to move on and do something else, then the parent will, if they get desperate enough, they'll abandon the chick and go eat. Like they have to- they have to stay alive.

Christian: Right.

Ellen: So they will leave their chick to go feed if they have to. Yeah, so that does happen sometimes, although the chicks will form their own huddle once they kind of get big enough where they can leave their parents' pouch, they will form their own little huddle and sometimes actually other penguins will adopt abandoned chicks.

Christian: Awww.

Ellen: Yeah, that- actually I was about to talk about this.

Christian: Oh!

Ellen: Yes. So, so dedicated our penguin fathers that there are many cases of male penguins forming couples and adopting abandoned eggs or chicks. This is actually very like, highly documented in captivity usually because people find it adorable and lose their minds about it because it's so cute. So I haven't, I actually wasn't able to confirm that any of these were emperor penguins. I found a couple of examples of king penguins, being their closest relatives. So Skipper and Ping were a pair of male king penguins at the Berlin Zoo who tried to incubate and hatch rocks and fish.

Christian: Awww...

Ellen: Yeah. They so badly wanted to hatch their own egg that they would find rocks and incubate them and like, try to hatch... Rocks. Yeah. So they wanted so badly to have their own baby that they were given an egg that had been laid and abandoned by its mother. So the zookeepers saw a mother lay an egg and she walked away from it, so they gave the egg to Skipper and Ping. The egg ended up not being fertilized, so it never hatched, but the zookeepers say they're going to keep trying. They'll try again next season that like, if another egg is abandoned, they'll give it to Skipper and Ping and let them try again.

Christian: How nice.

Ellen: Yeah. Another pair of male king penguins at the Odense Zoo in Denmark saw a chick left unattended, assumed it was abandoned by its parents, and adopted it as their own. When the parents returned for their chick, they were not pleased. So they got in a little fight, they got in a little penguin altercation and staff had to like, break them up and they did return the check to the original parents. But what happened was these two male penguins really wanted to have a chick of their own and they basically saw like, this chick that their parent just went to go, I dunno, swim or eat or something, and they were like, "Oh! Must be abandoned!" And like, just took it and left. So yeah, that was...

Christian: Swipe.

Ellen: Yeah. So they- the zookeepers there did say that they were going to try to get that chick- get those penguins their own chick too. And then of course the famous penguin couple, Roy and Silo. These were chinstrap penguins, so these are different entirely from emperor and king penguins, but these were chinstrap penguins who nested together as a couple for six consecutive years.

Christian: Wow.

Ellen: Yeah. And they eventually raised a chick, a female chick, her name was Tango, they raised her together and she inspired the children's book "And Tango Makes Three," about Roy and Silo and their baby chick Tango.

Christian: How cute!

Ellen: Yes, it's very sweet. There is this misconception floating around that we actually, just like an hour ago were talking about in the Facebook group, there is this misconception that penguins mate monogamously forever. A lot of people have this idea that penguins mate for life. That's not really how it works. So they engage in what's called serial monogamy, where they will have one partner for that mating season. So they'll have one partner that they stay with for that year, but then the next breeding season, a lot of times they will go back to the same partner, but they will often find another partner for the next season. Now, different species of penguins have different what they call divorce rates.

Christian: Oh no.

Ellen: Yeah. So for example, actually the emperor penguin, I saw their figures said that 80% of emperor penguins found a new partner with like, the next breeding season. So they're not as successfully monogamous as other species of penguins, like other species, it's much, much lower, it's like 30 or 40% so they actually are more likely to go back to the same partner over and over again. But it's not true that they stay with just one partner for the rest of their lives. That's not how they work.

Christian: Okay.

Ellen: Yeah. So I just wanted to get that out there. So the last thing I want to talk about for their ingenuity is that penguins identify each other to either reunite with their mates at breeding seasons, or when they come back from hunting, they need to find their family and get back to their chick. They can identify each other by these unique vocalizations. Yeah. So even in these massive colonies of thousands and thousands of penguins, they can pick out the one particular penguin they're looking for because they can tell their voices apart.

Christian: That's good.

Ellen: Happy Feet was like surprisingly accurate. How like, they identify each other by their voice and like the song that they sing is like unique to them. That's like surprisingly dead on.

Christian: But then Elijah Wood couldn't sing!

Ellen: No, he did a bad job.

Christian: He had to do the dance.

Ellen: He danced instead. But like that was a lot of things in Happy Feet were like surprisingly accurate. Like that part in the beginning where like the skua is like, diving down and trying to take the egg and the babies and stuff. That's true. That happens.

Christian: And then they did all those Queen songs.

Ellen: They did all the Queen songs and it was great. Happy Feet's a great movie. So that wraps things up for my 8 out of 10 for ingenuity, I thought they were pretty good. They have really good social interactions and that's...

Christian: Very good.

Ellen: Pretty cool. So for aesthetics, I gave them two different scores. For the adults, I give them 6 out of 10. I think they have a goofy-shaped body where they are very thick in the middle, but they're kinda like tapered at the ends?

Christian: I'm trying to think if I'm imagining the correct penguin.

Ellen: The emperor penguin is the one from Happy Feet. It's really tall now. I do, I will say that they have a very aesthetically pleasing color palette where they're mostly black and white. Their back has this sort of gradient where it's black at the bottom and it up towards the top. It's like a gray scale sort of ombre look that I think is really, really pretty, and then they have these splashes of yellow around like their face. They'll have these bright, bright, bright yellow splashes on their face and on their beak and stuff.

Christian: I see.

Ellen: So I think their colors are really pretty, but I actually don't think that the adult emperor penguin is very... Cute. They have the little eyes and... I don't know. I'm not a huge stan of the adult emperor penguin. Now, part two of my aesthetic score, the babies. 10 out of 10. Oh my gosh. It's literally just a little pointy cloud. That's all it is. It's just a little, it's just a little fluff that has a tiny beak and tiny eyes and it's just so cute I can't stand it. So number one, cutest baby animal in the world, but it grows up to be... You know, those like bowling pin shaped like toys that's like, you knock them over and then they pop back up? It's a bit what they look like.

Christian: Are you talking about Weeble Wobbles?

Ellen: Yes. That's kind of what they look like. So yeah. Um...

Christian: I bet they do fall down, though.

Ellen: I just find it hard to take them seriously with the way that they look. But yeah. So those are my two different aesthetic scores for the emperor penguin.

Christian: Very good.

Ellen: Yeah. So to wrap things up, their conservation status is near threatened. So emperor penguins are directly affected by changes to ocean temperatures, since they need massive amounts of sea ice in order to breed and raise their chicks. So as ice in Antarctica is continuing to decrease as severely as it has in recent years, penguins are having less and less space to start their families and their populations are declining. So you can help us protect penguins by you know, supporting environmental protection measures. I know there's been a lot in the news about the climate strike and all that stuff, so you know, follow that and, and do what you can to make our oceans better and protect penguins.

Christian: Yeah.

Ellen: That's all I got. That wraps things up for the emperor penguin for me.

Christian: Very good! Very interesting birb.

Ellen: Definitely a very cool bird to learn about. I guess to wrap things up for this episode, we have a couple of audience responses. I'll go first because mine is actually not a response. It was way back. So last week we talked about the bombardier beetle. You did. So Jungle Gym Queen was one of the people who requested the bombardier beetle, and I totally forgot to say this (or I forgot to pass this on to you), but in the Twitter thread where they requested the Bombardier beetle, they had this really delightful description of the bombardier beetle that I wanted to include.

Christian: Okay.

Ellen: Called bombardier beetles "chitinous incarnations of people after eating sugar-free Haribo gummy bears."

Christian: [laughs].

Ellen: And I really found that on point. I thought you would like to hear that and I neglected to mention it last episode, so I wanted to make sure we got that in there.

Christian: Excellent.

Ellen: Yep. It's all you babe.

Christian: Alright. I have a response from Melody Albright, who is one of our listeners on the Facebook page. So for last week's episode with the bombardier beetle, I reached out to Melody because she's been very active in the Facebook group and has a lot of knowledge about insects. So I asked her, you know, what are some interesting things about the bombardier beetle? And then she actually reached out to her friend Evan Waite, who recently got his Master's in Science while studying beetles.

Ellen: Wow!

Christian: Yeah. Evan says the coolest fact, in his opinion, is that the chemical compounds that make the explosion are held in two separate chambers, when released, they combine to cause the reaction. So that's what we were talking about last week, in the explosion chamber.

Ellen: Yes. The dramatically named explosion chamber.

Christian: So, again, we thought that was all very interesting because it's able to do that without blowing up itself.

Ellen: I always feel like, on some level, bugs are just little robots and I think this one's a battle bot.

Christian: Long range. Medium range? I don't know.

Ellen: I mean as far as bugs go, it's pretty long range. Most of them don't have that kind of reach. All right, well that's all we have for this week so thank you so much for joining us. I hope you enjoyed it and thank you very much to everyone who has been reviewing us on your podcatchers and letting your friends know about us. We really appreciate that. We've been seeing some really cool growth and it makes us really happy. You can connect with us on Facebook, Twitter, or Instagram. Just search the title of the show and you'll get there. Please come hang out with us in our Facebook group, which rules. Our Facebook group is so good. You guys make me so happy. It is called Just the Zoo of Us: Official Friend Squad, so come hang out with us on there and come be our friend. If you have an animal species that you want to hear us review, you can submit those to us. My email address is ellen@justthezooofus.com, or of course you can hit us up on social media. It'll get where it needs to go,

Christian: But also, also send us things you don't want us to review. I probably won't do anything with that information.

Ellen: If this is your first time joining us, if you scroll down a little bit in our feed, you'll see some of the monstrosities that Christian has brought to the table and subjected me to, because I have to sit here and listen to him talk about it every time, and then I have to edit the episode, which means I have to listen to it all over again, and then I have to do the transcript, which means I have to listen to it three times. I had to hear you talk about the botfly.

Christian: And see it in text form.

Ellen: THREE times I had to listen to that, and I had to type it out.

Christian: There it is.

Ellen: So, thank you so much for doing that to me.

Christian: Anytime.

Ellen: Like I said, the transcript of this episode and other episodes can be found at justthezooofus.com and our last note is that I'd like to thank Louie Zong for the use of his song "Adventuring" off of his album, Bee Sides.

Christian: Yes. Thank you for that. It slaps real hard.

Ellen: Okay bye.

Christian: Bye y'all.

21: Coquí & Bombardier Beetle

Ellen: Hey Friends, this is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And we are here with Just the Zoo of Us, an animal review podcast where we take your favorite species of animals and rate them out of 10 in the categories of effectiveness, ingenuity, and of course aesthetics.

Christian: We are not zoological experts. We do a lot of research and try our best to make sure we're presenting information from trustworthy resources, but if we get it wrong, let us know.

Ellen: Yeah, we will do our best to make it right.

Christian: I will travel back in time, assassinate myself, and take my own place to give better information.

Ellen: But then they wouldn't have anything to correct.

Christian: Time paradox. [X-files theme]

Ellen: Welcome to the Area 51 special. Just kidding. We're not really doing that, because we're recording this on the day of the Area 51 raid, but this will come out next week. But we do have a huge, probably our biggest ever update and that is that we have a ceiling fan in our office now.

Christian: I was like, "Uh oh, what did I forget?"

Ellen: Christian put up a ceiling fan in our office and that's the room that we record in and it's making it a lot more pleasant to record in here.

Christian: It sure is. It's normally sweltering.

Ellen: So hopefully that recording in pleasant conditions will just allow us to bring even better content.

Christian: Agreed.

Ellen: So, last week Christian went first with the jaguar. So this week it's my turn.

Christian: What do you got for us this week, honey?

Ellen: This week I am going to be talking about a beloved cultural icon: the coquí.

Christian: Ah!

Ellen: Yeah, the scientific name is Eleutherodactylus coqui.

Christian: I like that.

Ellen: Yes. It's a beautiful name. The species was requested by our friend Edwin Rivera. Thank you, Edwin. Edwin requested this saying that this is a species that is near and dear to his heart because the coquí is the cultural icon of Puerto Rico.

Christian: That's right. We learned a little bit about this in the JoCo Cruise earlier this year when we went to San Juan.

Ellen: We did. We got to stop by in San Juan for a little bit. Now we didn't hear the coquís and we didn't really get any exposure while we were there. Still...

Christian: Saw lots of references to it.

Ellen: Yes, lots and lots. This is a very popular animal in Puerto Rico. Just before I launch into it, I'm getting my information from the US Department of Agriculture's Forest Service, the Animal Diversity Web- we love them, we're always up in their business- and, this is interesting, the Journal of the Acoustic Society of America.

Christian: Okay. Interesting.

Ellen: Yeah. I'm really glad that we're talking about this animal because most of the animals that we talk about, I think we talk about their visuals a lot, which doesn't always translate super well to an audio medium. This animal is made to be talked about over an audio medium.

Christian: Excellent.

Ellen: Yes, this is perfect. So just to introduce you to my new friend, the coquí, their adult size is only up to five and a half centimeters, or a little over two inches, and that is like as big as they get.

Christian: Alright.

Ellen: So they're typically gonna be around an inch long. It's a little dude! It's a small frog. I didn't mention that they're frogs. They're frogs! They're tiny, tiny frogs. They are native to Puerto Rico where they can be found pretty much throughout the entire island, pretty much all over the place. Um, most notably the famous rainforest in Puerto Rico, El Yunque National Forest.

Christian: Oh yeah. Was that the one near San Juan?

Ellen: It's near San Juan, yeah. It was close to where we were, but not close enough for us to reasonably go there cause we had to be back.

Christian: Sure.

Ellen: But um, yeah. El Yunque rainforest. Now their taxonomic family is Eleutherodactylidae. These are rain frogs. That name comes from Greek and it translates to "free-toed." Not T-O-A-D, it's not a free toad. You can't go to the store and ask for a free toad. By "free-toed," they mean that their feet are not webbed.

Christian: Oh! Okay.

Ellen: Yep. They don't have any webbing between their toes, which basically just means that they're not necessarily adapted to be like aquatic. Their feet aren't adapted to swimming. This is more of a land-dwelling frog. Now, this family of frogs is known for its practice of direct development. So what this means is that the babies emerge from the eggs not as tadpoles, but as froglets. They develop through the tadpole phase inside the egg, and by the time they hatch from the egg, they have already grown legs.

Christian: I guess that makes sense if they're not in bodies of water usually.

Ellen: Right, right. Now there are over 700 species of frogs in this family, and 18 of them are different species of coquí,

Christian: Huh.

Ellen: Yup. So the one that I picked is just the common coquí. This is the one that you're going to find all over the island. It is the one that there seems to be the most information about, so that's why I picked it. There are a few other different species including some that are believed to be extinct. It's really interesting because they seem to have like, just developed on the island of Puerto Rico and that's it. That's pretty cool. Yeah, that is just your little introduction to the coquí. So I'm going to get into my ratings for this animal. So if you're joining us for the first time, what we do is we rate our animals in three categories, the first of which is effectiveness, and we define effectiveness as how good is this animal at doing the things that it needs to do. So these are physical adaptations that let the animal do a good job. So I'm giving the coquí a 7 out of 10 for effectiveness.

Christian: It's pretty good.

Ellen: It's pretty good. It's decent. So first of all, they have pretty good camouflage. They're just kind of a standard brown color, but they have markings that are, like brown-adjacent. So they could be tan or like light yellow or a darker brown. They just, they blend in with the wood of the trees that they're in or the leaves on the ground, stuff like that. They blend in very easily with foliage, so they're pretty good at staying hidden, which is good because they are ambush predators. So they do like, eat insects around them and stuff. They'll pretty much eat anything that can fit in their tiny, tiny little mouth, but they're ambush predators so they'll lay and wait until their prey is close enough for them to jump out at them and get. Their lack of a tadpole stage means that they don't actually need standing water. This is really good for living in a rainforest environment where there might not always be standing water available, like during the dry seasons or something. They also do absorb moisture through their skin like other frogs do, so they're really well adapted for living where they live in the rain forest, they don't necessarily need standing water to get by because they don't have to necessarily drink water, like through their mouth. They can absorb it through their skin.

Christian: Makes sense.

Ellen: Yeah. So kind of the most defining characteristic of the coquí is their voice. For being only about an inch long, they have an extremely loud voice.

Christian: Oh boy.

Ellen: Yeah. The cry of the coquí can be up to 90 decibels, which is about as loud as a lawn mower. This is kind of what they're most known for. I actually put more information about this in the ingenuity section.

Christian: Okay.

Ellen: Which I'm going into right now.

Christian: Oh, well here we are!

Ellen: It's time. So for ingenuity, we define this as behavioral adaptations that an animal has that let it do clever things. So maybe it has a problem that it needs to solve on a daily basis, or maybe there's an obstacle in its way that it needs to kind of figure out. These are smart things that an animal does. I give the coquí an 8 out of 10.

Christian: Really!

Ellen: Which is higher than I expected to give a frog.

Christian: Sure.

Ellen: This is a clever frog.

Christian: Oh boy.

Ellen: Yes. So, the coquí gets their name from their iconic call that they make. So, their name is actually onomatopoetic.

Christian: Like a Pokémon!

Ellen: Which is, by the way, onomatopoetic is my favorite word in the English language. It's so- yes! It's exactly like a Pokémon! They say their name. They do, and this is the only animal I can think of like this, but they do say their name. So the call, first of all, it's only used by males. Females do not make the sound. Females will make like, some small sounds but not very many. So when you hear a coquí, it is a male making this sound.

Christian: I bet I can guess what the purpose is, then.

Ellen: Yes you can, but hold on. It gets more interesting than that. So, they produce this call during the evening and throughout the night to communicate with other coquís. It's not necessarily like to, I don't know, ward off predators or anything. So what is distinct about the call of the coquí is that it is divided into two distinct parts, like how the name goes "coquí," the first part of the call is a low-pitched "co-" and then the second part is a high pitched "-KEE." So their cry sounds like "co-KEE."

Audio: [recording of a rain forest full of coquí singing]

Ellen: It's so precious. It's really cute. So the first part is much, much lower and the second part is much, much higher.

Christian: Sure.

Ellen: There is a very particular reason for this.

Christian: Ooh...

Ellen: Yes. So each part of their cry sounds the way it does because they're intended for different audiences. Male and female coquís have auditory neurons that are distributed differently from each other. Their brains are literally wired differently. Their inner ears are tuned differently, meaning that males and females cannot hear the same pitches. Females can hear much, much, much higher pitches than males can.

Christian: Huh.

Ellen: Yes. So, this is actually a really cool example of sexual dimorphism in the auditory system.

Christian: Yeah, for sure.

Ellen: Where they're actually processing their environment differently, based on male and females.

Christian: Huh.

Ellen: Yes. This is wild. This is so cool. What is even more interesting about that is that, so the "co-" part of the cry is directed at other males to warn them, like, "hey, I'm here, I'm a male. You need to know where I am so that you know to not be in my zone." Right, they're trying to like keep other males away from them. So that's what the "co-" part of the sound is. And the "-KEE" part of the sound is directed at females to let them know, "hey, I'm over here. It's me, a male. Come, come uh, hang out with me. Yeah, come get some." Basically. So in the absence of other males, they will skip the "co" and just do the "kee." And in the absence of females, they'll skip the "kee" and just do the "co."

Christian: Interesting!

Ellen: So they can like, kinda tell, they're like, "okay, it doesn't seem like there's any females around here, so I don't necessarily need to broadcast to them. I'll just do the 'co' part. So I'm just talking to like- hey fellas. Hey fellas." When they're done with that, they're like, "all right, now ladies."

Christian: Like that song.

Ellen: Yes. But so yeah, so they're talking specifically to whatever sex of frog is closest to them, and like they can tell who's nearby and they change their call based on who they're trying to talk to.

Christian: I wonder if that's based on what they can see, or what they've heard. Like maybe they can hear other males.

Ellen: Right. Like they can hear if there's other males near them. Right?

Christian: Yeah.

Ellen: So if they don't hear any other males nearby, they're like, okay, maybe I don't necessarily need to call out to the males.

Christian: Okay.

Ellen: Yeah. So I thought that was really fascinating. I put this in ingenuity because I figured like even though this isn't necessarily like a conscious decision that the frog is making, this just shows that they have adapted to the neurological differences between males and females and have this habitual behavior that's like, tailored to the whole auditory processing system of the different frogs.

Christian: Yeah, that's crazy.

Ellen: Yes! That is so cool! That's such high-level stuff. So, the next thing I want to talk about for their ingenuity is the coquís like to hang out in different parts of the trees based on what kind of time it is. So first of all, like the older ones, the older adult ones, you'll find them up higher in the trees than the juveniles who like to stay kind of closer to the ground. The coquí likes to hang out at the tops of the trees at night when it's nice and cool and it's kind of humid, and there's a lot of kind of like bugs flying around up in the tops of the trees, so they like to hang out up there. But then when the sun starts to come out, things start to dry up. It starts to get a little hotter, they will be like, hmm, I need to kind of get lower to the ground cause it's a little too hot up here. But, if they were to just kinda hop back down the tree, like try to climb back down the tree, they'd be really, really vulnerable to tarantulas, lizards, predators like that, that are coming out around that time of morning. So, they just jump out of the tree.

Christian: Oh.

Ellen: And fall to the ground. They're speedrunning getting back down to the ground.

Christian: Can I back it up a real- just real quick?

Ellen: Yeah, what?

Christian: Does Puerto Rico have tarantulas?

Ellen: Yes.

Christian: I did not know that.

Ellen: Yeah.

Christian: Huh...

Ellen: Big ol' spidders. They got 'em. Yeah. Which will eat the frogs cause the frogs are very small.

Christian: Okay.

Ellen: But so they will just jump out of the tree and fall to the ground and...

Christian: All that stuff? Nah!

Ellen: Yeah. So they just kind of daredevil jump right out of the tree and fall on the ground. This has led to people describing El Yunque Forest as raining frogs.

Christian: Ohhh, that's very good.

Ellen: Mmhmm. So what's funny is that you hear that and you think, "okay, they probably just mean either there's a lot of frogs there or maybe it rains really, really heavily." Like how you and I would say like, "it's raining cats and dogs" or something?

Christian: Yeah.

Ellen: Which I say we would say that, but I don't think I've ever said that in my life. I don't feel like it's as common as a phrase.

Christian: Yeah.

Ellen: But so how you and I might say it's raining cats and dogs., maybe this is like the Puerto Rican version, like it's raining frogs?

Christian: I guess.

Ellen: But no, it literally rains frogs. The frogs literally fall out of the sky.

Christian: I wonder if there's a particular time when it happens.

Ellen: Yeah. It's like early in the morning.

Christian: But like, at the minute, like could you set your clock to it?

Ellen: I really doubt it! I don't think it's like, "oh well it's 8:16" and then just every single- like hundreds and hundreds of frogs all at once.

Christian: Like when you go outside at a particular time, you have to remember to bring an umbrella.

Ellen: I don't think it's like that, but that would be really funny if it was. I'd really like that. So yeah, I thought that was pretty clever of them to figure out like, hmm, I can just use gravity to get down back to where I need to go without getting gobbled up.

Christian: I'm guessing it's such that they don't weigh enough to hurt themselves from that fall.

Ellen: Right. Yeah. They're just too small. They don't really take fall damage.

Christian: Maaan. Lucky.

Ellen: I mean, like you don't worry about something like a spider falling. It's like he's going to be fine. He's too little. It's just a little frog. He's fine. So yeah, they jump out of trees. I thought that was pretty smart of them to do that, to keep away from predators.

Christian: I agree.

Ellen: The last thing I wanted to talk about for their ingenuity, this is not a behavior that is specific to this species of frog, but it's still something that I found kind of endearing: since they do hatch into froglets rather than tadpoles, the coquí lays their eggs on plants rather than water. So this means that the eggs and the froglets are a little bit more vulnerable to different threats, like just environmental threats, but also little bit more vulnerable to being found by predators or messed with in some way. So male coquís will guard the eggs and- yeah, so the female like just lays the eggs and leaves, but the male actually hangs around the eggs and guards them to make sure that nobody comes along and gobbles them up.

Christian: That's a nice little trade off there.

Ellen: Yeah, they'll even stick around like for a few days after the froglets hatch to like! Make sure they kind of make it. Yeah. So they're actually good dads. That wasn't something I was expecting to find about a frog, you know? And I feel like when I think about frog parenting, I imagine just like, they lay their eggs and leave, which is what a lot of water-dwelling frogs will do. Like when they lay their eggs in the water, they'll just put them there and peace out, but the coquí will kind of hang around and make sure that their babies are okay. I thought that was really sweet.

Christian: Cute.

Ellen: So that wraps up my 8 out of 10 for ingenuity. This is a surprisingly clever little frog. I like it. I was kinda surprised to find all that stuff out, but...

Christian: Yeah, I imagine.

Ellen: I was very pleased by it. This brings us to my final category for the coquí. This is the aesthetics. For aesthetics, I gave it a 7 out of 10 as well. This is a pretty basic frog. It's really just a tiny little brown dude. I kind of gave it some points because it is pretty cute. They have these huge round eyes. They actually have a kind of a pointy nose. Their nose is a little bit v-shaped. Their markings have some variability, like some of them have yellow stripes down their back, some of them don't. They can kinda look a little bit different from one to the other. They don't all look the same. They don't all have the same markings.

Christian: Okay.

Ellen: I mean, they're pretty cute. They're nothing necessarily spectacular, but they have a pretty adorable little face as far as frogs go. It's a decently cute frog.

Christian: Okay.

Ellen: Yeah. So, going to wrap up the coquí by talking about some miscellaneous information, their conservation status is of least concern.

Christian: Good.

Ellen: In fact, coquís have been found as invasive species in Florida, California, and most importantly Hawaii.

Christian: Well.

Ellen: They are kind of wrecking shop in Hawaii. They apparently are a huge problem. So what happens is they come in undetected, either as eggs or as just tiny adults on imported plants. So they'll bring in like, bromeliads or other types of plants that are not native to that area. And the coquí is just so little, like you don't see it. You can just miss the entire frog, or it has like eggs on the plant or something. And then you bring that in and then they get everywhere and then they lay eggs and it just...

Christian: It's the perfect environment for them, too.

Ellen: It's very, yeah, it's very similar to what they're used to. So it's really easy for them to reproduce.

Christian: Probably fewer predators.

Ellen: No predators. Nothing in Hawaii will eat them, so they're just completely unchecked. This has happened in Florida a few times in the past, where coquí will sort of establish populations in South Florida, but Florida has the advantage of periodic freezes during the winter. Sometimes we'll have freezes, and those will usually kill off any coquí in that area. They can't really survive a freeze, but they can't really get a foothold in there. Like every once in a while there'll be a little flare up where like a bunch of them will show up, but they're not self-sustaining. You won't see a population of them lasting for a long time. However, in Hawaii, like I said, they have no natural predators to keep their populations in check. And in fact, in Hawaii there have been times when their population density was up to double or even triple what it was in Puerto Rico.

Christian: Dang.

Ellen: So this is like thousands and thousands and thousands of coquí in very small spaces.

Christian: So what is the impact? Is it eating important bugs or?

Ellen: Yes, so they're eating a lot of bugs. They're eating a lot of native insects. But also this is, I hadn't thought about this, but the excrement from the frogs changes the nutritional balance in the soil.

Christian: Yeah.

Ellen: So this is something that is okay for plants that are not native to Hawaii, but the plants that are native to Hawaii are used to a very, very different balance of nutrients in their soil. The plants that are native to Hawaii are used to that sort of volcanic soil, right? Where it's, it's very, very different from Puerto Rican soil. So when the coquí establish a big population, the poop that they're putting into the soil can really kinda change the ecosystem there.

Christian: I see.

Ellen: And they're also, you know, eating a lot of insects and they're competing with other predators in that area, so it's just not good.

Christian: Sure.

Ellen: And also another, not necessarily an ecological side effect, but an economical side effect is that they're very loud. They're extremely loud. Due to the density that they can establish in Hawaii, the sound produced by their calls can be completely deafening. You cannot hear anything over how loud they are. If they really get a foothold in an area, they can be so incredibly loud that you like, you can't even hear yourself think.

Christian: That's awful.

Ellen: You can hear them inside, like inside buildings, you can hear them because of how many there are and how loud they are. The Hawaii invasive species council describes them as "loud, incessant and annoying." That's not to devalue the importance of dealing with an invasive species that has really skyrocketed.

Christian: Honestly, I feel like the sound is the biggest problem and everything else is just secondary.

Ellen: Who knows? Maybe, I don't know. I don't know. I'm not on that council.

Christian: I think Hawaii in general is very, very careful about avoiding invasive species.

Ellen: Oh Gosh. It's like you can't take anything to Hawaii. Like you cannot take a plant, you cannot take a fruit, you cannot take an animal. Like you can't take your pet to Hawaii, they really have it on lock.

Christian: Yeah.

Ellen: So what's funny is that as negatively as they feel about the sound of the coquí because of how many there are there, that's in stark contrast to how Puerto Ricans feel about the sound of the coquí. Right?

Christian: Sure.

Ellen: So in Puerto Rico, their densities are much lower. They keep it to a reasonable volume. It's still loud, but it's very melodic. It sounds beautiful. They have that sort of melody to their call and it's, it does sound like music in the rain forest. It sounds really beautiful. They have really inspired a lot of art, they've inspired songs and poems and they've just really been a muse for artists from Puerto Rico and they're strongly associated with Puerto Rican identity.

Christian: That's awesome.

Ellen: Yeah, so I've been really charmed by this frog and I'm a big fan.

Christian: I think there's also a lot of music with influences from the coquí where the singer will imitate that sound.

Ellen: Oh yeah?

Christian: I heard a little bit of that while we were in San Juan.

Ellen: Yeah, it's- I can definitely see why they are so charming because I was reading an article from like the Puerto Rican tourism website that basically described their association as like, just like Puerto Rico, it's a small island, just like the coquí, we're small, but we have a big voice.

Christian: I like that.

Ellen: Yeah. So I was like, you know what? That makes sense. That makes sense. So, yeah, this is a great animal. I love the coquí and you know what? I didn't know anything about it before, like doing all this research, so...

Christian: That's fun.

Ellen: Yeah. Good animal. Thank you, Edwin.

Christian: Yes, thanks, Edwin.

Ellen: Before we move on to Christian's animal, just a real quick a shout out to our Patreon. We have a Patreon to help us grow, so if you want to help us out, if you want to support us and help us get bigger and better and also get access to some really cool stuff like a feed of the show with no ads and a patron-only discord and all sorts of other really cool stuff, come check us out at patreon.com/justthezooofus. For this week's episode, I want to thank our patrons, Briana Feinberg and Krystina Sanders.

Christian: Thanks, y'all!

Ellen: Thank you. Alright, Christian, what do you have for us this week?

Christian: For this week, I have the American Bombardier Beetle.

Ellen: Okay.

Christian: Scientific name, Brachinus fumans. Hope that's how that's pronounced.

Ellen: Sure. You're good.

Christian: This is the animal was requested by Jungle Gym Queen, as well as Sarah Beth Bradley.

Ellen: Thanks y'all. Good taste in bugs.

Christian: So, a lot of people have heard of the Bombardier beetle. That is actually a, you call it a grouping of several different species. I chose the American bombardier beetle just because of being local to us, I suppose. Although I don't think I've ever personally seen one of these.

Ellen: Definitely not.

Christian: And I'm pulling my information from also Animal Diversity Web, can be found at animaldiversity.org, and also MIT news, a particular article with which I will tell later, else giving away content.

Ellen: A grand reveal! No spoilers here.

Christian: But it can be found at news.mit.edu. So, a little quick talk about this beetle. Their adult size are about a half inch long, or one and a quarter centimeters long.

Ellen: Teeny.

Christian: Yeah. Not Big.

Ellen: It's like the claw of a chicken.

Christian: The fingernail? Bigger than that.

Ellen: Okay.

Christian: Yeah. You're trying to pull in them chickens. So these guys can be found, as the name might suggest, in North America in temperate zone woodlands and grasslands. They belong to the taxonomic family Carabidae, also known as ground beetles. As far as notable evolutionary relatives go, there's one called Panagaeus cruxmajor. I mentioned this one because it's interesting to look at. It's gold and black, and its markings look like it has a crucifix on it.

Ellen: Whoa.

Christian: Yes. And I also have a story towards the end of my segment that involves this particular crucifix beetle and Charles Darwin.

Ellen: So that's a little teaser for ya, stick around.

Christian: Yep. But kind of going back onto the family thing, this family includes 40,000 species.

Ellen: No, it does not. That's so many.

Christian: Sure does. I mean, now we're in the bug lands.

Ellen: That's true. Most animals are bugs. Most things are bugs.

Christian: Am I bug?

Ellen: Yes. We're all bugs.

Christian: So getting right into it. Effectiveness, this is where this particular species shines, in my opinion. I'm giving it an 8 out of 10.

Ellen: Alright. That's pretty good.

Christian: And that's because of what bombardier beetles are known for. To put it simply, bombardier beetles, they have a defense mechanism to where when they are threatened or startled, they will spray a hot toxin from their- the rear of their abdomen.

Ellen: Okay.

Christian: Let's talk about how that works a little bit.

Ellen: Yes, please.

Christian: So in the rear of the abdomen of the Beatles, they have two small glands. One produces hydrogen peroxide while the other makes hydroquinone. And then those two mix in a different part of the abdomen that is called the explosion chamber.

Ellen: No it's not!

Christian: It for sure is.

Ellen: Oh my gosh. This is a Zoid.

Christian: So these two- those two chemicals mix, and within that chamber is already two enzymes, catalase and peroxidase, and it's added into there to speed up the chemical reaction that takes place. So when these chemicals all come together, they produce a lot of heat and it reaches about the boiling point. So the temperature of this mixture, this cocktail of sorts reaches a hundred degrees Celsius, or 212 degrees Fahrenheit.

Ellen: There it is, okay.

Christian: It's heated up. It's creating a ton of pressure and then the beetle releases it as a steamy stream. This makes an audible pop when it happens.

Ellen: *popping sound*

Christian: Something like that, yeah. So yeah, it does this as a defense mechanism. So one, it's very hot and two, it's an irritant to most animals.

Ellen: Oh, so it's both hot and spicy.

Christian: Yeah.

Ellen: This a spicy gusher.

Christian: I don't suggest it though. Uh, and this reaction that's happening inside it happens in pulses.

Ellen: Oh, so it's not just like a stream?

Christian: Yeah, it's not a one and done thing.

Ellen: It's like just in case the first one wasn't enough.

Christian: Well it does a controlled pulse. It gets to the point where the pressure builds up to where the glands aren't able to put any more of the first two chemicals into the chamber, until it's released. It's a lot like an ignition chamber in a gasoline engine, actually.

Ellen: It sounds like it doesn't really have a lot of control over this.

Christian: It does, yes. So it's controlling these pulses and for how long it wants, but its control really comes into play with aim. So it has about 270 degrees of aim in any direction.

Ellen: Oh wow.

Christian: So it can effectively aim at wherever it wants.

Ellen: Does it ever accidentally like fire at itself or...?

Christian: So I've, I've seen it, I've seen videos of it doing this and I've seen it get its own leg or something. Cause usually in the videos, the way they prompt the response is they'll use tweezers or something to kinda like grab its back leg.

Ellen: Oh that's rude.

Christian: And they're like "Aah! *tssst*" and it'll usually get its own leg. It doesn't seem to do any damage. Something interesting there is that the anatomy of the beetles is in such a way that it doesn't harm its own internal organs with that said explosion chamber. So, and by the way, this is where the MIT article comes into play and that article was titled "How Some Beetles Produce a Scalding Defensive Spray."

Ellen: There it is.

Christian: So MIT was interested in it because of the potential applications in defense.

Ellen: Military defense.

Christian: Yeah. But also uh, engineering in general.

Ellen: Oh okay.

Christian: Right.

Ellen: I mean yeah they've basically got like a biological combustion chamber.

Christian: Right. Cause the inside of the beetle are such that, you know, some pieces are made to not expand under pressure whereas some are meant to expand but not permanently, and it's designed to retract back.

Ellen: Sure.

Christian: Just basic things going on inside it. Cause you know, you would wonder like how does it- how does it not blow itself up? So a lot of different insects do something like this, but what makes the bombardier beetle different is the reaction that makes it hot. The chemical itself, a lot of different insects use this kind of chemical, but the bombardier beetle can shoot it.

Ellen: Oh, a little extra sting to it.

Christian: Yeah. Yeah. They eat other bugs, a lot of which would be considered pests. So that's a plus.

Ellen: I'll take it.

Christian: Point off though: they cannot fly. They do have wings though, so they're considered vestigial.

Ellen: Oh man, you got the wings and you can't fly! Join the penguin club, I guess, man.

Christian: So just like, just like a lot of ground beetles, they have wings that are covered by like a cap over it.

Ellen: Sure, sure. It makes me think of like a scarab.

Christian: Yeah, just like that. Those caps are usually the prettiest part of beetles.

Ellen: It's decorative.

Christian: Moving on: Ingenuity. I gave it a 5 out of 10.

Ellen: That's probably the best they could have hope before.

Christian: I mean, it knows to use the chemical attack when it needs to.

Ellen: Sure. It probably takes a little bit of know-how to like, know how to aim.

Christian: I suppose.

Ellen: Get your trajectory right where you like you hit what you're going for, but not yourself?

Christian: I guess. Yeah.

Ellen: I guess it requires a fair amount of expertise. You're essentially a gunner.

Christian: Although there are situations where aim does not matter. For example, I saw a video of a toad eating one, not this particular species, but a bombardier beetle in general. And then of course, it does what it does best inside the toad, and the toad throws it back up.

Ellen: Oh really? Did the beetle survive?

Christian: Looked like it. Yeah.

Ellen: Wow! Man. Sure.

Christian: Since toads and frogs eat their things whole usually. Right?

Ellen: Yeah, that makes sense. Yeah. I guess they wouldn't really be trying to worry too much about like chewing it up and killing it first or anything.

Christian: Right.

Ellen: So I guess it would have that little escape opportunity.

Christian: Yep.

Ellen: That's pretty cool.

Christian: Yeah.

Ellen: You know, I like to give bonus points for like good, good, uh, evasive maneuvers.

Christian: Yeah. But again, I've considered that to be more of a...

Ellen: An effectiveness thing?

Christian: Yeah. And then the final category, aesthetics, 6 out of 10.

Ellen: That's not bad.

Christian: It's not the most interesting to look at as far as beetles go. It's not one of the pretty iridescent ones.

Ellen: Aw, man! I love those.

Christian: Yeah. So it's black and red, like a red orange mostly. The black part is its abdomen and the rest of it, like its head and its legs are reddish.

Ellen: It's a Sith beetle.

Christian: A what?

Ellen: Sith Beetle.

Christian: I don't know what- oh, a Sith, as in Star Wars?

Ellen: Yes! Because it's black and red.

Christian: Oh, okay. Yes. Excellent reference, wife unit.

Ellen: Thanks.

Christian: Alright. So that was my 6 out of 10 for aesthetics. Conservation status, there's no special listing.

Ellen: Sure.

Christian: Now, my fun little side story.

Ellen: The meat and potatoes. Let's get to it. I've been on pins and needles.

Christian: So this comes from the University of Cambridge, specifically their Darwin Correspondence Project. This comes from a letter that Darwin wrote to a Leonard Jenyns on October 17th, 1846.

Ellen: This is a throwback. Alright.

Christian: Yes. And it talks about the beetle that was related that I mentioned earlier, the Panagaeus cruxmajor.

Ellen: Okay.

Christian: The one that has a crucifix on its back.

Ellen: Cool. Cool, cool, cool, cool, cool.

Christian: And also before I go into it, just a reminder that the family is Carabidae, he will refer to it as Carabi. So I'm choosing a particular part of this letter. It's a pretty long letter, but this one I found interesting.

Ellen: An excerpt.

Christian: Yes. And it goes as such: I must tell you what happened to me on the banks of the Cam in my early entomological days; under a piece of bark I found two carabi (I forget which) & caught one in each hand, when lo & behold I saw a sacred Panagæus crux major; I could not bear to give up either of my Carabi, & to lose Panagæus was out of the question, so that in despair I gently seized one of the carabi between my teeth, when to my unspeakable disgust & pain the little inconsiderate beast squirted his acid down my throat & I lost both Carabi & Panagæus!"

Ellen: [laughter] Get wrecked! Oh my gosh. The, the... Audacity of this creature!

Christian: The little inconsiderate beast.

Ellen: You can- This is a letter that is what, 150 years old.

Christian: Yep.

Ellen: And you can just feel the seething like, frustration. The little inconsiderate beast! You can feel how mad he was. That is a timeless rage.

Christian: So I really enjoyed that.

Ellen: Gosh, I love that. You keep getting all these deep cuts, cause when what's his face was trash talking the manatee. You remember that?

Christian: Yep. I do remember that.

Ellen: That was a good one too. Dang.

Christian: So I think there might be a, I guess something to be taken away from this story. Something about greed or maybe the, you know... Bird in the hand worth two in the bush or something.

Ellen: A beetle in the teeth is...

Christian: Worth NOTHING.

Ellen: Is worth none in your hands.

Christian: So yeah.

Ellen: Oh my gosh. That was good. Oh, that's a good one. Thank you. Okay, so I guess the implication here is that like, he put a, uh, bombardier beetle...?

Christian: Wasn't a bombardier beetle. So remember I said a lot of these kinds of beetles will expel this kind of irritant.

Ellen: Oh, I see I see I see.

Christian: So I'm thinking this was the kind that was not a bombardier beetle, so it wasn't like super, super hot, but it was still an irritant.

Ellen: Okay, cool.

Christian: Yeah.

Ellen: Gosh, that's good.

Christian: So that's all I have for the American bombardier beetle.

Ellen: Good stuff. Thank you, my love.

Christian: Yes, and thank you again from Jungle Gym Queen and Sarah Beth Bradley.

Ellen: Yes. I have some audience responses that I'd like to share with you all.

Ellen: What'd you got for us?

Ellen: So this comes from our buddy, the Jungle Gym Queen, who also on Facebook goes as the Nagging Naturalist. Same Person. Yep. Twitter: Jungle Gym Queen, Facebook: Nagging Naturalist, who has a lot of really, really cool nature and conservation-based like, content. So very, very good stuff. Check them out on Facebook. So the Nagging Naturalist says in response to our peacock mantis shrimp segment in episode 19: "I have to contest Christian's peacock mantis shrimp score, or at least a feature he used towards their score, because for all of those color cones-" you remember how we talked about the color comes in the eyes of the peacock mantis shrimp- "peacock mantis shrimp can't actually process color the way we do. Being able to see more light waves than us doesn't necessarily mean they are good at interpreting what they're seeing. They're poor at discriminating between colors. However, when looking at what their photoreceptors focus on, it reveals that they have six receptors dedicated to processing on the UV spectrum as well as special crystalline cones that help filter UV specific wavelengths entering through their eyes. So being able to see UV light is thought to contribute to their communication, since they use polarized light to talk. Deep Look PBS did a good job covering the topic a few years ago," and then, uh, goes on to say "Counterpoint to my own, I have to give them props for having six pupils and hexnocular vision," as opposed to our vision, which is binocular, because two pupils. Theirs is hexnocular because they have six pupils. So I actually, I actually did look up this Deep Look PBS video on their vision and it was really interesting because it translated the light that they're seeing into light that we would be able to see, and it shows how they signal their location to each other using UV light that is visible to them, but not to us or anything else.

Christian: How do they produce the UV light though?

Ellen: It's not that they produce the light, it's that they have... I don't know if it's scales, but like their fins reflect that light that they can see that nobody else can see.

Christian: Okay. I guess they're just reflecting like the UV from the sun.

Ellen: Yup. Yup. They're just reflecting that light that nobody else would be able to pick up. This reminded me a little bit of when we were talking about the praying mantis having compound eyes, and you know, other bugs that have compound eyes, but the praying mantis having compound eyes doesn't necessarily mean that they see better than us because yes, they have very, very, very many eyes, but they don't see particularly well. So this is an example of quantity not necessarily meaning quality.

Christian: I see.

Ellen: Yeah.

Christian: Heh.

Ellen: So- Oh, do you now? Do you see? Spectacular. Thank you. All right. That's all I have. All right. Well, thank you so much to you, the listener for joining us this week as we hope you will every week forever for the rest of our lives as we continue making this show.

Christian: And even then after we upload our consciousness to a, uh...

Ellen: A hivemind.

Christian: I'm going to say a sentient otamatone.

Ellen: Okay, so we're going to have procedurally generated AI-concocted episodes. I really want to hear that. I like, I want to see someone do that thing where they take like, transcripts of our show- which are available on justthezooofus.com by the way- and feed it into like an AI program and then get a deep fake like, have like an AI-generated....

Christian: "I made this AI read a thousand hours of Just the Zoo of Us transcripts and this is what it came up with," it's just 5 pages of fartboat.

Ellen: Which has been retired, and then brought back by now, by the way, and that's some deep lore from our Facebook group. But so anyway, sorry for all of that that you just heard, but...

Christian: I'm not.

Ellen: Thank you to everybody who's been listening, especially especially thank you to people who have been telling your friends about us and reviewing us and rating us on your podcatchers. It means a lot to us and it makes us really happy and it makes us want to keep making this show, so thank you for doing that. You can connect with us on Facebook, Twitter, or Instagram. Just just search the title of the show. You'll get there.

Christian: Yeah.

Ellen: Also please come hang out with us in our really cool and awesome Facebook group that's called Just the Zoo of Us: Official Friend Squad. It's like the best group ever and you guys are really great and you make it an awesome group.

Christian: Good stuff.

Christian: We've been having a great time. If you have an animal species you want to hear us review, you can submit those to us. You can hit us up on social media and get those to us, or if you'd rather you can email them to us at ellen@justthezooofus.com. A transcript of this episode and all the other episodes can be found at www.justthezooofus.com and last note, I want to thank Louie Zong for the use of his song "Adventuring" off of his album, Bee Sides.

Ellen: Always a pleasure to listen to.

Christian: Yup. We love it. In fact, you're about to hear it right now. Here it comes.

Christian: Oh!

Ellen: Bye!

Christian: Bye yall!

20: Jaguar & Bearded Vulture

Christian: Hi everyone, this is Christian Weatherford!

Ellen: And this is Ellen Weatherford.

Christian: And you're listening to Just the Zoo of Us, a podcast where we take your favorite animals and give them ratings from 1 to 10. Or, I guess it could be zero to 10.

Ellen: We did give a zero, didn't we?

Christian: I don't remember.

Ellen: I think you gave the botfly a zero for aesthetics. I think

Christian: That makes sense. So yeah. Thanks for coming to our podcast. We give those ratings in three categories: effectiveness, ingenuity, and aesthetics. We are not zoological experts.

Ellen: Nope, not yet. They haven't given us our honorary zoology credentials yet. We're working on them.

Christian: I want mine printed on a crystal stein.

Ellen: I'm hoping that if we just make enough of these, eventually somebody will give us an honorary degree in zoology.

Christian: That's probably how it works. While we are not experts, we do try to get our information from trustworthy resources. I think that's it for the intro. Yeah?

Ellen: Yeah. Let's jump right in! Every single passing second that I'm not talking about my animal for this week is physically painful to me and I really want to get to it.

Christian: Yeah, you can't see, but Ellen is a visibly shaking as if a glass being resonated by a sound.

Ellen: I'm vibrating with energy to talk about this animal. I'm so excited about it.

Christian: But you're gonna have to wait cause I'm first!

Ellen: That's right. Christian's up first this week. What do you have for us?

Christian: This week, I have the jaguar (jag-wah), also known as the jaguar.

Ellen: You said jag-wire. That's weird. Why did you say it weird?

Christian: How do you pronounce jag-wire?

Google: That's pronounced "jaguar."

Ellen: Jag-war!

Christian: Jaguar.

Ellen: Thank you.

Christian: G-W-A-R, like that band. Okay. This week I have the jaguar.

Ellen: Thank you.

Christian: Scientific Name, Panthera onca.

Ellen: Panthera... Onca.

Christian: I assume that's how that's pronounced. O-N-C-A.

Ellen: Sounds right.

Christian: This species was submitted by Brandon Everfolly.

Ellen: Who has described the jaguar as his favorite animal.

Christian: It's also a close to home species for us. We have a professional football league named after them, the Jacksonville Jaguars.

Ellen: Yep.

Christian: I don't have any other information about that.

Ellen: I'm sorry guys. We're not sports fans, but we know about the Jaguars cause we live here. But that's really about the end of my information that I have. Apparently if you watch The Good Place, there's a lot of references to them.

Christian: There's also a a chant, but we won't go... We won't go there.

Ellen: No, we won't disturb your families and pets with our... With our cry.

Christian: I'm pulling information this week from once again, Animal Diversity Web, also NationalGeographic.org and, finally, panthera.org. So, a little basics about the jaguar. I'm going to pronounce it differently every time.

Ellen: Please don't. Please do this normal.

Christian: Ja-goor.

Ellen: I hate this episode already.

Christian: Maybe this is why people refer to the football team as the jags.

Ellen: This is a hot mess of an episode.

Christian: I'm learning so much. Adult size, so the jag... You know, the scientific name would be easier in this case. So the jaguar, the head and body length is 5 to 6 feet, or approximately 150 to 180 centimeters.

Ellen: That's a big kitty.

Christian: Yes, very big. Just the body alone is about as long as I am tall, basically. Just the body, because the tail is 27.5 to 36 inches, or approximately 70 to 90 centimeters.

Ellen: Long tail for a long cat.

Christian: Very long. They weigh from 100 to 250 pounds, or 45 to 133 kilograms. And what's interesting about their size is they can vary quite a bit depending on where you find them.

Ellen: Oh, where you find them?

Christian: Yes.

Ellen: Oh, interesting.

Christian: So for example... Well, so first of all, males are larger, but also going back to the geographic point, the largest ones are found in Brazilian Pantanal, while the smaller ones, I should say, the smallest ones are found in Honduras. And speaking of locations, you can kind of get an idea of where they're located based on what I just said. But they are found in 18 countries across Latin America, from Mexico to Argentina, Mexico being the southernmost country in North America, all the way through most of South America. And while that sounds impressive, that's actually smaller than what it used to be.

Ellen: Oh.

Christian: So for example, today, they're rarely spotted in the southwest USA...

Ellen: Hehe. Spotted.

Christian: Heh! No, aesthetics is later!

Ellen: I had to get one good pun in. You always get all the good ones.

Christian: You're right. So yeah, even today you can- there are rare sightings of them in the southwest USA, though there's not thought to have been a breeding population in over 50 years.

Ellen: Wow.

Christian: They're often found in forests, rainforests, scrub forest and swamps. But they're very often found in were called riparian habitats.

Ellen: Riparian?

Christian: Yes.

Ellen: What does that mean?

Christian: Which means areas next to a body of water.

Ellen: Oh, okay.

Christian: So usually river or stream. They belong to the taxonomic family Felidae. That's just the cat family, basically.

Ellen: The kitties.

Christian: But a more interesting evolutionary relative is its genus, Panthera. So that genus is also nicknamed the roaring cats.

Ellen: Roaring cats!

Christian: And the other things that are in there are lions, leopards and tigers.

Ellen: Okay. So these are the ones that roar as opposed to what, mew?

Christian: Mrow. Like cheetahs.

Ellen: Oh, that's true. Oh, I love the sound cheetahs make. It's so cute.

Christian: Yup. I think our own cat is actually doing this to us right now through the door.

Ellen: Hopefully our mics don't pick it up.

Christian: Here's hoping. So I'm just gonna jump right in. First category, effectiveness, how good do they do the things they do?

Ellen: These are physical adaptations.

Christian: Yes. Um, like wings, claws, uhh...

Ellen: They have one of those things.

Christian: Back mounted... Water cannons.

Ellen: Turrets. Yeah. We've talked about an animal with turrets.

Christian: I was referring to Blastoise, but...

Ellen: I was talking about a chameleon, but all right.

Christian: Okay. So effectiveness. I'm giving the jaguar a full 10 out of 10.

Ellen: Not surprising.

Christian: Shouldn't be. Because they have strong jaws that are meant to kill with a single bite. And I will talk a little bit more about that in my ingenuity section, but just know they have very good jaws meant for this purpose.

Ellen: Good chompers.

Christian: Overall, they are built for power, not speed.

Ellen: Really?

Christian: Yes. They're able to do short sprints if they need to, but that's not really where they excel.

Ellen: That makes sense because they live in pretty densely forested areas. Right? Not a lot of really sprinting room.

Christian: Right.

Ellen: Probably not a lot of area for them to necessarily run.

Christian: Yep, exactly.

Ellen: Makes sense.

Christian: They can drag very heavy prey. I'll come back to that in ingenuity, actually.

Ellen: Okay.

Christian: They can climb trees, of course, with their big claws.

Ellen: Big. Meaty. Claws.

Christian: They're good swimmers, which is odd. A lot of the big cats actually go great lengths to avoid bodies of water, but with the jaguar, it not only loves the water, but hunts in it.

Ellen: Hunts in the- what! Hunts IN the water?

Christian: They're very good swimmers.

Ellen: Huh! Like it gets in the water and like, waits for things to...

Christian: It will go after things in the water.

Ellen: What.

Christian: Not just that, but it's an option for it.

Ellen: This is an amphibious cat. It's an all-terrain cat.

Christian: It likes the water. Don't know. It eats lots of different prey. These include peccaries, tapirs, deer, caimans, turtles...

Ellen: Caimans being like, the crocodilian.

Christian: Of South America.

Ellen: Huh.

Christian: Yep.

Ellen: Okay. Get it.

Christian: Turtles, snakes, porcupines...

Ellen: Oh!

Christian: Yeah. I guess it just, uh...

Ellen: Forbidden snack.

Christian: Prickly boy. Fish and large birds. And at the beginning of that list I mentioned peccaries, which I didn't-

Ellen: I think it's a peccary. [pronunciation correction]

Christian: Peccaries?

Ellen: Yeah. I think that's it.

Christian: So anyway, I didn't know what this was prior to reading this. It is a animal that looks a lot like pig...

Ellen: ...Okay.

Christian: Lot like pig.

Ellen: Much like pig, yes.

Christian: But it's actually not the same as the pigs that you and I are used to, which come from Europe. I won't go into any other detail about that because maybe that would be a future animal.

Ellen: You already got to talk about one pig!

Christian: Oh, that's... Did I?

Ellen: You talked about the warthog.

Christian: Yeah, you right.

Ellen: So you did talk about one pig already. Well, maybe when we do a 30 to 50 feral hog segment, then we can come back to the peccaries.

Christian: And they're also, the jaguar is a keystone species. One definition of that phrase is a species on which other species in an ecosystem largely depend, such that if it were removed, the ecosystem would change drastically.

Ellen: I would imagine this would be the case with it being such an Apex Predator.

Christian: Yeah, yeah.

Ellen: That eats literally everything in its sight.

Christian: It's definitely at the top of the food chain. It's really, it's only real threat is humans.

Ellen: Dang. Get countered.

Christian: Yeah. And then finally, for effectiveness, built in camouflage. So the way its fur is, and the patterns, it lends itself to blending in with the shady forest.

Ellen: A lot of times it's really easy to confuse a jaguar with a leopard because they just kind of have a similar sort of shape, and they both are just kind of like brown cat with spots. But you can tell a Jaguar from a leopard because the jaguars spots are in the shapes of rosettes. So, how they're not like a circular spot. It looks like a rose.

Christian: Yeah. Yeah. Which I actually have that term later on in, in the aesthetics part.

Ellen: Oh, okay- well then you do have it then!

Christian: I was just going to talk about what the spots look like. I wasn't going to compare it to the leopard.

Ellen: Oh, okay.

Christian: Um, I think also a big tell is where you are currently located, right? Cause those are different continents.

Ellen: Yeah. Very different. Well, one other thing is that when people talk about a black panther, it could be a jaguar or it could be a leopard.

Christian: That makes sense.

Ellen: It's just either one of those that has melanism. That's all.

Christian: Yes. So, moving on to ingenuity. This is the smart things that does. Tactics, using tools, that sort of thing.

Ellen: Clever boy.

Christian: Once again, full 10 out of 10. So first of all, I alluded to this before, but they're very stealthy. You know, they got those big paws, they have the camouflage, and their main method of hunting is to pounce on prey from concealed spots.

Ellen: Oh, so they hide and wait?

Christian: Yes.

Ellen: Oh, this is a, this is a rogue.

Christian: So that could be from dense vegetatio, that could be from a tree branch, that sort of thing. And now I want to talk about how they kill with a single bite.

Ellen: How they kill with a single bite?

Christian: Yes.

Ellen: With a single bite, yes.

Christian: Well, they go for the single bite. It might take a couple, but what they're going for is two different things. They'll either go for the neck, and what they're going for there is suffocation. Or they'll use their canines to pierce to the back of the skull.

Ellen: Really?

Christian: Yes.

Ellen: So that requires some sort of understanding of the anatomy of the prey that they're going for, that like it will do extra damage if I hit them in these particular spots.

Christian: Yeah. And then, for some kinds of animals, or prey I should say, they might not have both as an option. So for example, there's a very popular video out there that you can see of a jaguar hunting a caiman. It might be labeled as a crocodile, but it's most likely a caiman. You'll see this jaguar's swimming through a river coming up to a sandbank that has a caiman on it, looking the other direction, just kind of basking. Swimming up behind it, gets onto the sandbank and jumps on it and just bites it in the back of the head.

Ellen: Oh my gosh. That takes such confidence.

Christian: Yes.

Ellen: That it has to know for sure that it can take that caiman.

Christian: Yeah. And this one is, it was at least the same size as it, so it's not like a tiny little baby one.

Ellen: That's almost arrogance at that point. It's like, yeah, this crocodile is just chilling, doesn't even know I'm here, doesn't want anything to do with me. I'm just going to go ahead and K.O.

Christian: Hey, um, Icarus, stay away from that sun. That scaly, scaly sun. So yeah, that's an interesting method, I should say. And then also, kind of coming off something I said earlier, is their ability to carry large heavy things. What they do is after they kill their prey, they will carry it off to a secluded spot to eat them. It's been recorded that they can even drag away things as large as the sea turtle.

Ellen: I'm sorry, a sea turtle?

Christian: Yes. A sea turtle.

Ellen: Where did they find a sea turtle in the rainforest?

Christian: On the beach, I guess. Weighing up to 34 kilograms, or 75 pounds.

Ellen: Wow.

Christian: Yes. And that's with its mouth.

Ellen: Yeah. Cause they're having to use all of their paws to climb up, so that's just pure like jaw and neck muscle.

Christian: Yes. And if you see close up pictures of jaguars, you can kind of tell that they have that beefy, beefy jawbone.

Ellen: Yeah. It gives their head a very wide and...

Christian: Almost square.

Ellen: Yeah, very boxy shape. Yeah. It gives them a very broad shape to their head that I think makes their face very definable.

Christian: You know, it's odd. I saw a picture of one yawning, and you could see the inside of its cheeks and whatnot. It honestly reminded me of like, the American pit bull.

Ellen: Yeah. I feel like their fur is not very thick, so you can see sort of the definition of their muscle under their fur, cause it's kind of a thin layer of fur. So you can see like exactly how muscular they are.

Christian: Yes. Speaking of fur, that brings us to the final category: aesthetics. This one's self-explanatory, how...

Ellen: Pretty.

Christian: How pretty they be... 10 out of 10.

Ellen: Across the board, a perfect score!

Christian: Yep.

Ellen: 10, 10, 10! The judges!

Christian: Two of them were sick. Just right off the bat, they're just absolutely beautiful. They're very pretty.

Ellen: I agree.

Christian: Um, so I'm just going to talk about what they look like, for those that may be not so familiar with what they look like. But they have an off-white belly, and their base coat can range from a pale yellow to a reddish brown, and their black spots like we talked about earlier, they are rosette shape. It's on their body and limbs. Melanistic jaguars, like we talked about earlier, they are fairly common and have a black base coat, and the spots are barely visible but they're still there.

Ellen: You can see them in like, the right light.

Christian: Direct sunlight, I feel like.

Ellen: Yeah. Then you can kind of see that the spots are still there.

Christian: Yeah. But, you know, how often are you going to see a jaguar in direct light, right?

Ellen: I mean, we have jaguars at our zoo.

Christian: And they're always sleeping.

Ellen: And they're ALWAYS sleeping. Except for one time, I saw one that was like rolling around on a rock and it was really cute.

Christian: I did see that they are more active around when the sun is setting, in early nighttime.

Ellen: Okay. That would explain it then. Cause I'm always there really, really early in the morning.

Christian: Yeah. They'll still do stuff throughout the day. It's just they're more active at that time.

Ellen: That makes sense.

Christian: But yeah, 10 out of 10. I think they're really cool looking. Like you mentioned, they have very nice fur, their eyes are very striking and they have the teeth and the color, it's just- it all comes together in a nice little package. Miscellaneous info about our jaguar friends: conservation status, they are near threatened based on the IUCN Red List. They've been eradicated from 40% of their historic range. They are often poached for their hide, teeth and paws. So unfortunately-

Ellen: Their paws?

Christian: Yes, their paws.

Ellen: What?

Christian: Yeah.

Ellen: That's not something I've heard before, I don't think.

Christian: I'm not sure what the use case is. Probably just taxidermy.

Ellen: A trophy of some sort maybe?

Christian: But yeah, so unfortunately with how beautiful they are there, their hides are in high demand in the illegal poaching market. Um, they're also killed by farmers in an attempt to protect their livestock, cause unfortunately, it's kind of cyclical where you know, as they're losing habitat and prey, sometimes that's their only option, is to resort to killing livestock.

Ellen: It doesn't work out great for the farmers, but you got to do what you gotta do.

Christian: Yeah. Yeah. So the jaguar is the largest cat in the Americas and is the only representative of the genus Panthera. Like I said earlier, Panthera is the roaring cats. So of course you have lions, tigers and leopards are elsewhere in the world.

Ellen: Makes you wonder how the jaguars got over here and all the other roaring cats stayed behind.

Christian: Yeah, I did come across some more prehistoric studies on this species, but I didn't go too deep into it.

Ellen: Oh.

Christian: Yeah. But it's- it's out there for those that are curious. I also want to talk about their babies...

Ellen: YES THANK YOU.

Christian: And this will be my final topic, but their babies are very, very cute. Don't have any other way to describe that, but here's some facts about them.

Christian: Yes!

Christian: Their offspring are called cubs, of course. Females will drive away the males after mating, and especially after the cubs are born. So after that point, it's just Mama. They give birth to an average of two cubs, although it can be anywhere from one to four, and their cubs are born with their eyes closed, like many other cats. And they don't open until they're two weeks old.

Christian: Just little blind kittens!

Christian: So they're little helpless kittens at that point.

Ellen: Oh, bless those little sweeties.

Christian: They nurse for the first five to six months of their life. After that, they start hunting with their mom, but their mom is still largely supplying them with food early on. They're pretty much dependent on the mother until they're two years old. They're kind of by themselves usually, and they only meet up for reproduction.

Ellen: Yeah. They don't travel in packs or anything like that.

Christian: Yeah.

Ellen: In our local Jacksonville Zoo, a have now two jaguars. Right? They got two new jaguars? Last week I went to the zoo and I actually kind of went to go see the jaguars, but um, I saw one of them and she was just sleeping on a rock, as she tends to do.

Christian: Every time.

Ellen: Yep. That's all they're ever doing is just sleeping on rocks.

Christian: Yeah.

Ellen: I have gotten some really cute pictures of the ones that the zoo where like, one was like... He was on the rock, but he was like rolling around. Yeah, like doing that kitty cat thing where he was like rubbing his head on a rock and it was really cute. But other than that, they're usually just sleeping.

Christian: I love it.

Ellen: They're really hard to find.

Christian: Oh, like in the exhibit.

Ellen: Yes. They're very hard to find! You can see that like, natural camouflage at work.

Christian: Yep. For sure.

Ellen: They're kind of a big um, point of pride I think for our zoo because the jaguars are kind of our local like, sports team mascot. So people really have a lot of connection to the jaguar around here, which is weird cause like they don't live here.

Christian: Used to, long, long time ago.

Ellen: Yeah. But like way before Jacksonville was a thing. So yeah, it's just kind of weird because it was like, this is not an animal that has anything to do with our city, but it's our sports team mascot, so everybody loves it.

Christian: Yeah. So in the areas that they're found, they have a huge cultural significance, especially with the indigenous peoples of Central and South America. You can see that in prehistoric paintings and depictions, even

Ellen: Lots of Aztec and Mayan art that depicts jaguars. And they're usually of like holy- they're like deities.

Christian: But I can see why. I mean they're pretty impressive.

Ellen: Yeah. Cause I would imagine that way back during the time when these civilizations were kind of in their prime, the jaguar was probably the primary threat. I feel like if you don't have a firearm, you kind of don't stand a chance against a jaguar.

Christian: Probably. So yeah, that's the jaguar.

Ellen: Excellent. Thank you so much! I really enjoyed that. That was really cool.

Christian: No problem.

Ellen: That is our first ever perfect score. Complete total sweep.

Christian: Really? I guess it had to happen eventually.

Ellen: I think it was well earned. I hope it's the first of many.

Christian: We'll see.

Ellen: 10, 10, 10.

Christian: Well now we have the rubric to which...

Ellen: The jaguar is now the gold standard by which every other animal will be measured.

Christian: Exactly.

Ellen: Very good. Thank you, my love.

Christian: Any time.

Ellen: So, before we move on to our next animal, I just want to let you guys know real quick that we have a patreon out there floating around Patreon.com/justthezooofus. That's what we are using to kind of gather some support that will help us grow the show, so we're really, really excited about that. You can get access to some really cool extras, so a feed of the show without ads, which is probably becoming increasingly desirable as we have picked up some new sponsors, so our ad segment might be growing a tad, so if you want to skip all of those, you can do so for as little as $1 per month on our Patreon. We also have other cool things like a patron discord server and I'm going to start sending out photo prints to our patrons once a month, which is going to be a lot of fun. So check us out at Patreon.com/justthezooofus for this week's episode. I want to thank our patrons, Briana Feinberg and Krystina Sanders. Thank you so much for supporting us.

Christian: Yeah, thank you!

Christian: Alright, hun. The time has come.

Ellen: Thank you. Thank God. I'm so excited.

Christian: What is your animal for this week?

Ellen: This week, I am so delighted to be bringing you, Ellen Weatherford presents: the bearded vulture.

Christian: The burb?

Ellen: A big- yeah, the big one.

Christian: Okay!

Ellen: The bearded vulture, also known as the lammergeier. That's their German name, the lammergeier.

Christian: Interesting.

Ellen: Yeah, and that translates to lamb vulture. Or like, lamb taker.

Christian: Uh oh.

Ellen: Yeah, that's a misnomer. They don't do that. The scientific name of the bearded vulture is Gypaetus barbatus.

Christian: I like it.

Ellen: Yes. This species was requested by Jennifer Perez. Thank you, Jennifer.

Christian: Thanks, Jennifer!

Ellen: Yeah, and I'm really glad that you did because I've been really wanting to talk about this animal. This is so good. I'm getting this information from the World Wildlife Fund for Nature, Animal Diversity Web, and the National Audubon Society. If you've never met the bearded vulture, this bird has a length of o1 to 1.25 meters, or 3 to 4 feet. That is the length of the body.

Christian: Oh no.

Ellen: The wingspan of the bearded vulture: up to 2.8 meters, or 9 feet.

Christian: Yeah...

Ellen: A nine foot wingspan.

Christian: Yikes.

Ellen: Yes. This is a living dinosaur. I mean all birds are living dinosaurs, but this one's especially so. This one is SUPER dinosaur.

Christian: It's got the "oomph" to back it up.

Ellen: Now the females, this is interesting- the females tend to be the larger ones.

Christian: Okay!

Ellen: It's really easy to identify bearded vultures. First of all, because of their size. They are absolutely massive, but it's easy to tell them apart from other vultures because bearded vultures have a thick mane of feathers around their head and their neck, which most vultures have that pretty characteristic bald head.

Christian: Right.

Ellen: They don't. They have a very, very thick mane of feathers. This is particularly spectacular because it is white with these black bands around their eyes, so it gives them a very striking, masked appearance.

Christian: Fierce.

Ellen: Yes, but they get their name bearded vulture from a tuft of black bristles that they have underneath their beak that looks like a little... Looks like a little beard poking out. You're going to find these big boys way high up in the mountains throughout Europe, Asia and Africa. You find them in rocky craggy mountainous areas, but you can kind of find them all... They're especially well known in the Pyrenees and the Alps, but you can also find them throughout like the Balkans and even in Africa.

Christian: Okay. I was wondering why it had a German name and that makes sense.

Ellen: Yeah. Their populations are kind of declining in those areas, but you can find them in like the Alps and the Pyrenees.

Christian: Gotcha.

Ellen: Now their taxonomic family is Accipitridae, which we've visited before with the osprey.

Christian: Oh yeah.

Ellen: This is the same taxonomic family as many hawks, eagles, and Old World vultures.

Christian: Okay.

Ellen: So I want to take a quick minute to talk about "Old World vultures" versus "New World vultures." These are two different groups. As their names would imply, Old World vultures are found in Africa, Asia and Europe, whereas New World vultures are found in the Americas.

Christian: Okay.

Ellen: They're not related. They have some very similar characteristics like the bald head and kind of the hooked beak, they're scavengers, but they're no more related to each other than like, eagles and hawks and stuff like that.

Christian: Interesting.

Ellen: No further relation. So this is an example of convergent evolution. They're separate species that have really nothing to do with each other, but they developed the same traits independently of each other for the same reasons. So both of these groups share the identifiable bald head, which is believed to be an adaptation that keeps their head and their face from overheating.

Christian: Oh, okay.

Ellen: Some people also say that the lack of feathers on their face keeps the blood and the gunk from the carrion from getting their feathers stuck together, but there's not really a lot that kind of shows that. So it's just kind of belief that it's for the cooling factor of keeping their face clean.

Christian: Okay.

Ellen: One major difference between the two groups of vultures is that New World vultures rely more heavily on their sense of smell to find their food, whereas Old World vultures are scavenging based on sight, so they actually can't smell very well. They are just using their eyes to find their, I wouldn't say prey cause they're not really hunting, but they're using their eyes to find their food rather than a sense of smell. So, although bearded vultures are usually considered an Old World vulture, they're not actually very closely related to the other Old World vultures. No more related than like a hawk or an eagle.

Christian: Okay.

Ellen: So you can tell that they're very different from other vultures by just like, their appearance and the way that they look. Them and Egyptian vultures form this sort of subfamily of the Accipitridae family. So they're kind of their own thing, a little bit. So that's your background on the bearded vulture.

Christian: I'm already very excited.

Ellen: He's great. So I'm gonna move into my ratings for the bearded vulture. First up, we've got effectiveness. For effectiveness, I'm giving the bearded vulture an 8 out of 10.

Christian: Okay.

Ellen: So the bearded vulture's diet is really unique in that it consists almost entirely of bones.

Christian: Oh!

Ellen: Just bones. About 80 to 90% of what they eat is bones. Yeah. That's pretty... Not usual.

Christian: Right.

Ellen: That's not very standard fare for most animals. So bones are a really uncommon dietary choice for animals because of how nearly impossible it is to eat and also to digest. So in order to actually eat bone, bearded vultures have an extremely acidic stomach that is strong enough to dissolve bone. So they're rewarded for this adaptation with a food source that ends up being really, really high in calcium. Like turns out if you actually can eat it, it's really, really like just chockfull full of like calories and...

Christian: Like, ah... #iatethebones.

Ellen: I can't believe you found a way to...

Christian: I think I'm the only person on the planet that remembers that commercial.

Ellen: You are definitely the only person on the planet that not only remembers that commercial, but quotes it on at least a daily, if not like... Three to five times a week, you quote this commercial. So if anybody out there still remembers the "I ate the bones" commercial, please connect with Christian because he needs a support group.

Christian: Please...

Ellen: Validate Christian. So not only are the bones themselves very nutritionally dense and high in calcium and pretty good for them to eat, there's also a marrow inside that is just chock full of nutrients. It's very, very good to eat if you can get to it.

Christian: Sure. People eat bone marrow too.

Ellen: Yeah. So that's a nice little treat for them once they break through all the bone in there. And what's also really cool about having a diet based on bone is that there's pretty much no competition for bones.

Christian: Guess so.

Ellen: There's very, very low demand from other predators.

Christian: Except time, I guess.

Ellen: I mean, at the maybe like, century level.

Christian: A glacial pace.

Ellen: Yeah. Like I don't think they-

Christian: I gotta eat this before it goes bad.

Ellen: I don't think they have to worry about that. But so they don't really have to compete for their food with anybody else, other than like other bearded vultures.

Christian: These do not extend to Africa, right?

Ellen: Yes. They're in Africa.

Christian: These are in Africa?

Ellen: Yes.

Christian: So hyenas maybe?

Ellen: I mean they'll- they'll eat them sometimes, but it's not really very important to them. They're really after the meat. So this is just a really interesting and unique food source for them. Now, they have really, really excellent eyesight. It lets them spot their meals from way high up in the sky. So when they're flying around way, way, way up high in the air, they can see well enough to spot the carrion, which is particularly impressive since they're eating dead animals, their prey is not moving. Right? Imagine how good your eyesight has to be to spot a completely still target from way up in the air while you're flying around.

Christian: Probably difficult.

Ellen: Yeah! And when you're flying around in the mountains, like it's just- it's hard to spot stuff already, so yeah, they have good eyesight. I did deduct a couple of points for the fact that they do eat bones, but their beak and claws aren't actually strong enough to break the bones.

Christian: Oh!

Ellen: Yeah. When I saw that they eat bones, I thought, "oh, that must- like they must be strong enough to break through, like a hyena." Right?

Christian: Sure.

Ellen: The hyena has those powerful jaw muscles that lets it just snap right through, but the bearded vulture actually cannot break the bones.

Christian: Okay.

Ellen: However... It has a plan.

Christian: Okay...

Ellen: Which brings me to ingenuity. I give the bearded vulture a 10 out of 10 for ingenuity. Even though by itself it is not strong enough to break through the bone, if a bone is too tough for the vulture to break on its own, it grabs the bone in its talons, carries it up high into the air, finds a jagged rocky- like a crag or something like that, and drops the bone from the air, letting it fall, fall down all the way down to the ground and shatter the bone into pieces.

Christian: Huh! I guess I've got to be pretty big bones, huh? Because else you're not gonna get that speed.

Ellen: Yeah. These are like- yeah, these are like femurs and stuff like that. These are like the big chonky bones. So they drop them all the way from up in the sky and the bone falls and uses the sheer force of fall damage to shatter the bone into little bitty bits. And those small pieces are small enough for the vulture to swallow whole.

Christian: Sounds so unpleasant, just the swallowing part mostly.

Ellen: I mean, for us, sure. But that's how they eat the- that's how they eat bones. They swallow the chunks of them whole.

Christian: I guess that's their only option.

Ellen: Yeah. I mean, like I said, they can't exactly chew them. So, yeah, I felt like that was a very, very interesting tactic when you yourself are not strong enough to do the cracking.

Christian: I wonder if there's any recorded events where maybe this bird would drop a bone, I don't know, in the middle of the street.

Ellen: So there is kind of a... An old Greek myth saying there was like, a dude that got killed by a falling tortoise that was dropped from the sky by an eagle that was believed to be a bearded vulture.

Christian: Oh!

Ellen: Yeah, so that was actually the next thing I was going to say, that they use this airdrop strategy to kill tortoises.

Christian: Oh.

Ellen: Yeah. So they use it to break open bones, but they will also use it to prey on tortoises that would otherwise be too tough for them to break through.

Christian: In the story, did the tortoise died?

Ellen: I'm sure. I don't think the tortoise was really the focus of the story.

Christian: It's my focus.

Ellen: I know, I'm way more concerned about whether the tortoise was okay.

Christian: Some Greek guy...

Ellen: So I thought that was really interesting that they're using it to negate that armor so that they can get at the little chewy bits inside. Another pretty smart thing that they do, also concerning fall damage, is that they have been documented cornering larger prey- these are larger prey like ungulates, like goats that you might find up in the mountains or something...

Christian: Sure.

Ellen: They corner them at cliff edges and back them up by intimidating them by flapping their wings. So they have these huge nine foot wide wings. Right?

Christian: Sure.

Ellen: They flap their wings and just make this really big display, like this really big threatening display and the prey gets scared and the vulture presses forward and just backs them up further and further until they fall over the edge of the cliff.

Christian: Dang...

Ellen: Yeah. They just intimidate them into falling off the cliff and then they die.

Christian: I mean, what I'm taking from this is make sure these birds never run out of bones because, jeez, they'll go to great lengths to make bones.

Ellen: Yeah. When they can't find carrion, they will make carrion. So what is pretty cool is that when a bearded vulture spots carrion, when they find like a dead animal that's already died and it's sitting there, they will actually not go straight in for it. So they'll kinda chill nearby and keep an eye on it and they'll wait for other vultures to come in and pick the meat off. So other vultures are there for the meat, so they'll wait for other scavengers to move in, basically clean the carcass off, and then once those scavengers move on to find other carcasses, then the bearded vulture comes in and finishes the job.

Christian: How bizarre is that for the other vultures, do you think? It's like the person waiting, like, "hey, when you finish that pizza, I want the crusts. You better leave the crusts."

Ellen: And you're like, "are, are you- Are you sure? There's like...."

Christian: It's not even cheese-stuffed, bro.

Ellen: Yeah. Like "are you sure you want-" and they're like "GIVE ME THAT CRUST"

Christian: Or you're next!

Ellen: And then they- and then they pick up the crust and bring it to the top of the restaurant and drop it off the roof. Something else that's not bone related to the bearded vulture. When you look at an adult bearded vulture, you might notice that its feathers are bright red or orange. Yeah. They're not naturally like that. They're white. This is actually intentional. The bird is doing this on purpose. So what they do is they bathe in these springs where the water is really, really high in iron and then the iron clings to their feathers and it stains their feathers dark orange or red.

Christian: That's pretty cool.

Ellen: It's really cool! They're doing it on purpose, and you can tell that they're doing it on purpose because when they go back home to their nests, they rub their feathers on their babies and on their eggs to get the iron on them too.

Christian: Huh!

Ellen: Yeah. You can tell that they're doing it on purpose cause they're like trying to spread it.

Christian: But why?

Ellen: So there have been a few suggested reasons for why they're doing this. None of them have really been completely confirmed, but one kind of leading theory is that the iron in the dirt that they're getting in their feathers protects them from parasites, and that it can kind of serve as almost like an antibacterial or something, but that it keeps them healthier and protects them from parasites.

Christian: I have an alternate theory.

Ellen: Well, there's one more.

Christian: Okay.

Ellen: Another theory is that the bright colors are a display and that they're doing it for looks either to intimidate rivals or to attract mates. It could be either one.

Christian: Okay, so my alternate theory is related to number two.

Ellen: Okay. What is it?

Christian: Can't eat bones if you ain't cute.

Ellen: There is also the third theory that they're in it for the gram. They're doing it for the aesthetic. That could be it.

Christian: Treat yourself.

Ellen: Yeah.

Christian: Bearded vultures deserve fashion too.

Ellen: They do. You're right and you know what? They excel at it. So yeah, I gave them some points for that. Whatever their reasoning may be, they sure do seem dead set on it because apparently they will do this even in captivity. So this is a behavior that they don't necessarily have to learn from their parents, this is something that they will do even if- they will do it in captivity, if they're left undisturbed. So they won't do it if you're watching them. Yeah, it's pretty interesting.

Christian: It doesn't want to give away the trade secrets.

Ellen: They're apparently very private. Like there's a lot of things in captivity that like they won't... They won't do their normal stuff if they're in captivity and like, being observed. They're very secretive.

Christian: Can't let us see how they blend their rouge.

Ellen: You mean you're not going to find any bearded vulture makeup tutorials on Youtube?

Christian: Check out this eyeliner, with the wings.

Ellen: I can't believe you've done this. I don't wear makeup, but I find makeup tutorial videos so soothing to watch. I love watching them. I love watching people do makeup, even though I don't wear makeup myself. So I would love to see a bearded vulture makeup tutorial. I would love that.

Christian: I've unfortunately expended all of my knowledge and vocabulary about makeup.

Ellen: I know you're at your limit. I'm sorry to have done this to you. Contour, you got that one?

Christian: That sounds like a bird.

Ellen: That's a condor. *gasp* Condor contours! That's going to be my new youtube channel. It's going to be all about vultures and their beauty regimen.

Christian: Very good.

Ellen: So bearded vultures are normally solitary unless they are part of a breeding pair. So during their mating season, they will mate and form these duos. So when they're breeding, a male and a female- or, on rare occasions, two males and a female...

Christian: Okay...

Ellen: ...Will share their territory and kind of work together to protect their nest and feed their offspring. So there have been actually some recorded cases of triads with two males. They don't particularly enjoy it. They still fight a lot. They still fight a lot, but they will at least...

Christian: But not enough to like...

Ellen: They won't kill each other.

Christian: Or to go and do their own thing.

Ellen: Yeah. Not enough to leave, I guess. So what is kind of interesting about bearded vultures, as opposed to other species of vultures, is that they feed their offspring actual carrion. They don't... They don't regurgitate to their young, they bring the food back to the young and give it to them.

Christian: Can you imagine regurgitating bone shards?

Ellen: Oh my god. I mean then you're-

Christian: I don't know how it gets down in the first place. I don't want to chance it coming back up.

Ellen: So maybe that's why they bring the carrion back instead of. uh- But so they do bring the softer things back for the babies. They'll bring back meat or something that's a little bit easier for the babies to eat. Now young bearded vultures actually engage in play.

Christian: Ooh!

Ellen: So what they do is they'll fly really high up in the air and then they'll do these dive bombs down towards the ground. And while they're on their way towards the ground, they will do all sorts of really cool tricks. Like they flip and they roll and all these other acrobatic sort of displays. Um, so these are really important skills for them because they'll benefit them later in life when they're fighting to protect their territory, or to court a mate. Actually a bearded vultures that are courting each other will do these insanely technical like sky dances where they fly all around each other and do all these crazy tricks where they tumble in the air and they'll like, grapple with each other and they'll actually fly towards each other and like fall to the ground and like grapple as they're falling.

Christian: Well. Yeah, that's, that's how we met. Remember? We, um... We, we each had a blue angel fighter jet and then we did these sick stunts in the sky.

Ellen: We did. Not a lot of people know this, but we're actually Mech anime characters.

Christian: NANI?!

Ellen: We're actually anime characters and we've been, uh, we have been Gundam this whole time.

Christian: Am I Gundam?

Ellen: Yes. We're all Gundam. So like the shoebill- which we talked about way, way, way, way, way back when, I think that was episode six we talked about the shoe bill- When they lay their eggs, they have a backup chick just in case the first chick dies.

Christian: Huh.

Ellen: Yeah. This is kind of a common motif, huh, in a animal moms, that they...

Christian: You pick the worst animal moms.

Ellen: Kinda have a backup baby.

Christian: Wait. Are we still in ingenuity?

Ellen: Yes.

Christian: And you gave a...

Ellen: 10.

Christian: *suspiciously* Hmmm...

Ellen: Which I know- Okay. So the reason I... I actually think I gave the shoebill some ingenuity points for doing this.

Christian: Okay.

Ellen: But the reason I took them off for the quokka is that the quokka actively murders her children.

Christian: No it doesn't!

Christian: Well, she won't hesitate to.

Christian: Just stabs and throws the corpse at the thing.

Ellen: Well, she yeets them onto the ground and leaves them to die, so she's a little bit meaner than the- this is more of the sort of thing where they will have two babies and then the one that's older and stronger they will prefer and then a lot of times, with the younger one, they just won't feed it. Like they won't even bother with it and they'll die.

Christian: No, I get it. It's like Pokemon. Catch two Pidgeys, get rid of the weaker one.

Ellen: Yeah, it's- they're IV farming.

Christian: Yep.

Ellen: They're trying to catch the one with better IVs. But so, the chick that hatches later than the other one usually dies pretty quickly and then is fed to the other chick. I mean, it seems to be working out for them nicely.

Christian: Not for the second chick! That's okay, I guess.

Ellen: Yeah. So. That's my 10 out of 10 for their ingenuity. I think they're just, their behavior is just fascinating. They're a really, really interesting animal. And that brings us to our final category for the bearded vulture: aesthetics. I also gave it a 10 out of 10 for aesthetics. This is such a beautiful bird. I- in my notes for this section, I have one word and one word only. One bullet. One word. Wow.

Christian: Such beauty.

Ellen: It's just, wow, this is really gorgeous bird. And especially when you get that fiery red in there. Gosh. And it's like they're intentionally making themselves prettier. It's so cool. So yeah, this is just a really beautiful bird. They have this really incredible face where they have this long, curved beak and their eyes are this bright red and it's surrounded by these black bands. You know I'm crazy about a good face mask. Any sort of animal with like a built-in bandit sort of look to it. Oh my gosh, I love it. And then they just have that really magnificent mane. It's very fluffy and their feathers are very thick and billowy and it's just very majestic. Everything about it is perfect and I love it. So 10 out of 10 for aesthetics. I love this bird.

Christian: Alright.

Ellen: If you've never seen one and you have no idea what I'm talking about, Google bearded vulture right now and you're welcome. So I'm going to wrap up the bearded vulture with some miscellaneous information. Their conservation status is near threatened with populations decreasing. A common cause of death for bearded vultures is collision with power lines or other manmade structures, but according to the IUCN, the biggest threat to the bearded vulture and a lot of other vulture species is indirect poisoning.

Christian: Ohh.

Ellen: Yeah. So a lot of times insecticides or other more serious poisons are placed in bait and set up to bait other predators like foxes or wolves that are more prone to picking off livestock. So this kind of makes farmers upset and they don't like it, they want to kill the foxes and the wolves, so they set out bait with poison and unfortunately then the vultures will come and eat it and they themselves will get poisoned and die. Even though they're not really the target, they still will suffer for it. Now this is often done illegally, so there are a lot of controls in place for like what kind of insecticides you can use. A lot of times people will just do it anyway just because they want to kind of protect their livestock. So right now, there's currently a campaign against this. This campaign is called the Balkan Anti-Poisoning Project, and they're putting in a lot of work to raise awareness and prevent the both intentional and unintentional killing of wildlife like the bearded vultures. If you're listening to this and you currently set out poison bait for any sort of wildlife, don't do that. Actually, people in our area sometimes will do this. They will set out poison traps for feral cats or, I don't know, raccoons or coyotes or something. I have definitely heard of people in Jacksonville setting out poison traps for different animals for whatever reason, but then that ends up then affecting cats or dogs or possums or other sort of animals that aren't necessarily hurting anybody. Stop doing that. Don't set out poison traps for anybody for any reason. Just don't do it. And that's all I've got. That's the end of that for me.

Christian: Well thank you, babe. It's a very good bird.

Ellen: You're welcome. Yeah, I was telling you earlier this week that I think the bearded vulture is my new favorite animal. It's just the best one. Number one, best animal.

Christian: Glam bird.

Ellen: Uh, now that we're done with our animals, we like to do this segment at the end where we read some responses that we've gotten from our audience. Our audience members are pretty great and we love you all and you are delightful and many of you are zoological and ecological professionals and have a lot of really interesting things to contribute. So we like to give you guys an opportunity to weigh in at the end here. So I have two responses I want to read. The Jungle Gym Queen on Twitter, who can be found at @junglegymqueen, pointed out in response to our manta ray segment in episode 18 that giant manta rays have actually been documented passing the mirror self-recognition test. This is a test that indicates self-awareness, and therefore implied to be high levels of cognitive function. So I kinda dug into this a little bit to see, you know, how this was done. So this test was performed in a study by Dr. Scilla Ari and Dr. Dominic D'Agostino. This was in 2016, and what they did was they exposed these two captive giant manta rays to a mirror and observed their responses. The manta rays responded to their image in the mirror, not with social displays, so they have certain behaviors that they will exhibit when they see another manta ray...

Christian: Sure.

Ellen: They didn't do that though, as you would expect them to behave towards another manta ray. But instead, they showed these frequent, unusual and repetitive movements in front of the mirror. So things like circling or doing something over and over again that they were doing in front of the mirror that they don't normally do. This suggests that they did understand the reflection to be not another manta ray, but themselves. Yeah. So what do you think, babe? Do you think that factors in, do you want to retroactively update their ingenuity score?

Christian: I don't remember what I gave it for ingenuity.

Ellen: I think you gave them a seven.

Christian: Let's bump it up by one, then.

Ellen: Okay. Plus one to ingenuity.

Christian: Yes.

Ellen: Great. So yeah, thank you. Jungle Gym Queen.

Christian: Yes, thank you.

Ellen: Who I believe also runs a Facebook page under the name, The Nagging Naturalist. So yeah, go check all that content out. It's very good.

Christian: Love alliteration.

Ellen: Yes, I know you do. And the other thing I wanted to include was that George Diaz on Twitter said, uh, I'm assuming this is in response to our giant panda segment, which we did in episode three, he says, "I'm surprised you didn't mention that there are only two pandas that are not owned by China, but in fact owned by Mexico. They reside in a zoo in Mexico City and their names are Xuan Xuan and Shin Shin. They're a gift from China back in 1975, second generation, first to be born in Mexico."

Christian: Interesting.

Ellen: Yeah, so I also did a little bit of digging into that as well. Back before the 80s, China would often give pandas to other countries as diplomatic gifts, tokens of affection from China to other countries. So actually the U.S. received some, Canada received some, a lot of different countries in the world received these gifts of pandas and Mexico got some too. And currently Mexico is the only country that still owns like, the descendants of those pandas that they received from China.

Christian: Oh, okay.

Ellen: Yeah, that's just some, some additional information.

Christian: That's interesting.

Ellen: That there are two pandas in the world that belong to Mexico.

Christian: Well cool. Hopefully they are able to keep the line going.

Ellen: Yeah. So thank you George for pointing that out to us.

Christian: Thank you.

Ellen: So yeah, that's what we've got this week. Thank you so much for joining us. This was a lot of fun and we're really, really grateful for everybody that has been listening and everybody who has been rating and reviewing, that means a lot to us. We get some really cool, we get some really nice reviews and that always makes us really happy. So thank you for doing that.

Christian: And thank you for your word of mouth to your friends, telling them about us.

Ellen: Yeah, that's really great. We're always really excited to have new people join us. It's really fun. So you can connect with us on Facebook, Twitter or Instagram. Just search the title of the show. That'll bring you to us. Please, please, please come hang out with us in our Facebook group cause it's poppin. The title of the Facebook group is "Just the Zoo of Us: Official Friend Squad!" And it is a lot of fun. We have had really fun things like we had a poll going on last night about whether you prefer the ranger or the druid when wanting to incorporate animals into your D&D party. So we've been- which that was also on Twitter too.

Christian: Yeah, I saw.

Ellen: Yeah, so we've just been having a lot of fun out there. Come hang out with us on Facebook or on Twitter or you know, wherever you're... Wherever you most enjoy participating in social media. If you have an animal species that you'd like to hear us review, you could submit those to me at my email address: ellen@justthezooofus.com, and last note, I would like to thank Louie Zong for the use of his song "Adventuring" off of his album Bee Sides.

Christian: Yes. Thank you so much.

Ellen: We love it. Thank you so much for letting us have that. It really sets a nice tone for our show and we really love it.

Christian: Yes.

Ellen: All right. That's all I got. You want to go get some pizza?

Christian: I would love to get some pizza.

Ellen: Let's go get some pizza.

Christian: Yesss.

Ellen: Bye.

Christian: Bye everyone!

19: Quokka & Peacock Mantis Shrimp

Ellen: Hey there, Weatherfriends.

Christian: Hi everyone.

Ellen: This is Ellen Weatherford.

Christian: And Christian Weatherford.

Ellen: And we are Just the Zoo of Us, your favorite animal review podcast where we take your favorite species of animals and we review them and rate them out of 10 in the categories of effectiveness, ingenuity and aesthetics.

Christian: We are experts in many things, but zoology is not one of them.

Ellen: That's true. We do a lot of research and we do our best to make sure that we're presenting you really good information from really trustworthy sources, and we always cite those sources so you know where our information is coming from. You know, we're not just making this stuff up. Well, we're making the numbers up. The numbers part is arbitrary. We made that stuff up.

Christian: I mean we didn't create the number system

Ellen: We did, actually. Numbers didn't exist before us. We invented the numerical scale.

Christian: We got lazy and decided to make some numbers just upside down version of other numbers, so there.

Ellen: Some people call them negatives.

Christian: I meant like, nine and six, but okay.

Ellen: That's the dumbest joke we've ever made on this whole show. We're 19 episodes in and that was the stupidest thing either one of us has ever said. So yeah, we cite our sources. That's all I was going to say about that.

Christian: Third bullet...

Ellen: So yeah, we do our best to make sure that we're giving you really good information. But by all means, if something seems amiss to you and you are a zoological expert, feel free to shoot us a message. Don't worry. We are very friendly. We do not bite and we will be sure to make it right.

Christian: But make sure you give some context that message, because if some rando just messages my personal Facebook says, "how dare you give a 9 when it should have been a 10?" And I don't know what you're talking about.

Ellen: And it's actually me from another account. Just mad that you didn't give the um, what was it that I thought you should have done a better one?

Christian: Literally everything.

Ellen: I'm always so mad at you for your numbers. So Christian, last week you went first.

Christian: You're right.

Ellen: So this week it's my turn and I'm really, really excited because we have some crowd pleasers this week.

Christian: What do you got for us this week?

Ellen: So, we decided this week to do two of our most highly requested animals. We kind of bumped them up due to popular demand, and mine that I'm talking about this week is the quokka!

Christian: Quokka?

Ellen: Quokka! This is spelled Q. U. O. K. K. A.

Christian: Alright.

Ellen: The scientific name is Setonix brachyurus.

Christian: I didn't think you can get much more difficult than quokka, but it did!

Ellen: So quokka, I think, is a really cute name because it reminds me of the noise that Pac-man makes.

Christian: Ah, very good.

Ellen: So the quokka was requested by Alyssa Años, Dena Tygart and Taylor Gordon-Wood. And Taylor, by the way, made our beautiful cover art.

Christian: It's very good.

Ellen: Yes, it's excellent. Oh-

Christian: Now available on merchandise.

Ellen: Yeah! Oh, now available on merch, which I haven't mentioned on the podcast yet. Oops. But it's out there. Anyway. Also, Alyssa Años, my cousin, requested this animal in the ideal request format. She sent an email to our email address and it literally was just the word quokka.

Christian: Was it in the subject or the body of the email?

Ellen: Both.

Christian: Ah, same word twice then.

Ellen: It's, it was just one word: quokka. And I was like, well, received.

Christian: To the point.

Ellen: Message received.

Christian: Efficient.

Ellen: Yes. . I'm all about efficiency. So we're here with the quokka. So the information that I'm getting on the quokka I have gathered from Nature Conservancy Australia, the Australian Museum and Rottnest Island Wildlife's fact file on the quokka.

Christian: All right.

Ellen: So you'll never guess where this animal is from.

Christian: Antarctica.

Ellen: So, I'm going to introduce you to my buddy, the quokka. At their adult size, they are 40 to 55 centimeters, or 15 to 22 inches long. Their tail adds another 25 to 30 centimeters, or 10 to 12 inches. So this is roughly the size of a house cat or maybe a large chicken.

Christian: So when you were saying 40 to 50, I don't know why, but I was thinking of, oh, she's about to say feet. I know she's about to say feet!

Ellen: Forty to fifty FEET. TALL.

Christian: Australia why?!

Ellen: Oh, you haven't heard about the 50 foot tall marsupial roaming the wilderness of Australia?

Christian: It's that weird forced perspective the camera does, just the opposite.

Ellen: So, anyway, you're going to find these little dudes in one very, very specific place called Rottnest Island. This is an island in southwestern Australia, near the city of Perth. Now, there are some other smaller populations in the mainland of Australia in sort of the southwestern forests, but by far the largest population is on Rottnest Island. There are an estimated 10,000 of them on this island.

Christian: Wow.

Ellen: Yeah, so actually what's interesting is that this island, Rottnest Island, was named after the population of quokkas living there. So the Dutch explorer- I'm going to do my best here Willem de Vlamingh?

Christian: Okay.

Ellen: Vlah-ming? Vlay-ming? Something like that. He was the one that named this island, and he described these quokkas as giant rats, which makes sense when you look at them, they look like they could be rodents, and they also have the long, hairless tails that rats have.

Christian: Aw man.

Ellen: Yeah, I know you're not a fan of it. But anyway, so he saw that and assumed that they were types of rats. So he named the island Rottenest, which translates to rat nest.

Christian: Makes sense.

Ellen: A nest of rats. Yeah. So they're actually with the island is named after, even though it's not a very cute name. And you would not think they were very cute based on that name. I mean it's got the word rot in it. Right? That doesn't sound great. That doesn't sound very appealing.

Christian: Yeah...

Ellen: But anyway, so the taxonomic family that the quokka belongs to is called Macropodidae. These are macropods. Macropods are the family of marsupials that includes kangaroos and wallabies.

Christian: Okay.

Ellen: So there are marsupials outside of the macropod family. Those are going to be like possums.

Christian: So, is the quokka a marsupial itself?

Ellen: Yes. Yes, all macropods are marsupials.

Christian: Okay.

Ellen: A lot of sources that I saw described the quokkas as a type of wallaby, and then that made me dig a little bit further into what counts as a wallaby. Because I guess I always thought a wallaby was like, a certain type of species, but actually the term wallaby doesn't have a very strict genetic definition. So the term wallaby really just refers to a small macropod that is not a kangaroo.

Christian: Oh, that's pretty general.

Ellen: Yeah. So quokkas are kind of considered part of that because they don't- it's just not a very strict term. But the quokka is the only species in their genus, Setonix. They don't really have any other species within that genus, but they are related to the wallabies.

Christian: Okay.

Ellen: Yup. So that's just kind of your little introduction to the quokka. I'm going to get started with our rating system. We start with effectiveness, which for us here at Just the Zoo of Us (if this is your first time joining_ for us, effectiveness is physical adaptations that the animal has that make them do a good job at the things that they're trying to do. So these are things that are built into their body to make them do a good job. I gave the quokka an 8 out of 10 for effectiveness.

Christian: Okay.

Ellen: The bulk of the points I gave them are for their very fast and efficient reproduction. They are very quick at it. Gestation period is only about a month, so the joey- oh, I should even say being a marsupial, their babies are called joeys. Just like Kangaroos.

Christian: Ah, okay okay.

Ellen: Yeah, they're their joeys. So the joey is born about a month after the mother mates. Now they are super teeny tiny when they're born and they live in their mother's pouch for six months. And then after six months they come out.

Christian: Yeah, because I mean at the earliest stages, they might as well just be a fetus that's just no longer on the inside, right?

Ellen: A jelly bean, really. It's a small bean. So now here's where it starts to get a little bit rough after this. So I'm just going to put a quick little content warning that the following is a little bit... Um, it's challenging content so be careful.

Christian: Suited for mature listeners.

Ellen: I don't... Um, yeah. So, the joey lives in its mother's pouch for six months, at which point it emerges. Now the mother keeps a backup- at least one, sometimes more- backup, undeveloped joeys in her womb. They're not developed fully yet, but little fetuses, she keeps them in her womb just in case the first one doesn't work out.

Christian: Okay.

Ellen: So if things don't go so good with that baby, she's got some backup babies ready to go. In the oven. Now, this is especially useful for them because- I'm so sorry, but one of the quokka's escape tactics when chased by a predator...

Christian: Oh, no.

Ellen: Is to abandon the joey, take it out of the pouch and just kinda smoke bomb, kind of leave the baby there and use it as bait to distract the predator for long enough for the mother to get away.

Christian: Oh no...

Ellen: Yeah, it's not good.

Christian: I guess it's kind of that whole, "I don't need to outrun the predator, I just have to out run the rest of you."

Ellen: So this might seem counterproductive. Why has the mother fed its baby to a predator? So you have to not view this through the human lens of morality and don't make assumptions about ethics for quokkas. Think about it. It's very easy for the mother to make more babies. The baby can't make more mamas. It just mathematically, for their population, makes more sense.

Christian: I mean, sure, there are animals that eat their young, so...

Ellen: Yeah, they haven't necessarily eaten their young, but they've fed their young to a predator to kind of buy time for them to get away. So in the grand scheme of things, she is typically okay with sacrificing one of her babies.

Christian: Can I ask in this part of Australia, what is the most common predator they they have to contend with outside of humans?

Ellen: So on this island, there are feral populations of invasive species like cats and foxes.

Christian: Okay.

Ellen: Yeah. So they, they have those to kind of compete with. I would imagine things like large birds of prey, uh, snakes, maybe? Reptiles?

Christian: I'm just trying to think of things that they would need to outrun. Um, I guess that wouldn't be... Reptiles, per se.

Ellen: I don't know off the top of my head, but...

Christian: No worries. I was just curious.

Ellen: Yeah. But so yeah, that's why one of the biggest things that people say is to please do not scare the quokkas because they will smoke bomb their babies.

Christian: Oh no.

Ellen: Yeah, it's not great. They'll just kind of spike them right on the ground and peace out.

Christian: Do they come back and just be like... did it work out?

Ellen: No, they do not.

Christian: Oh, they just assumed.

Ellen: Yeah, so um, bad moms, but... I mean, you gotta give them some logic points for that, right?

Christian: Sure....?

Ellen: So, yeah, I mean they will leave their babies behind and everything, but it's super easy for them to make more. So I gave them some effectiveness points for that.

Christian: I guess I would've put that in the second category, personally. But...

Ellen: You know, I couldn't bring myself to. I couldn't bring myself to award them ingenuity points for infanticide. I just couldn't let myself do that.

Christian: I mean...

Ellen: Moving on. Away from this.

Christian: Next!

Ellen: Leaving this whole topic in the dust. So, quokkas living in some pretty dry areas of the world, they are able to store fat deposits in their tails. So this allows them to survive for up to a month at a time without water or food. This is really important because during the dry summers, water gets really scarce on their island and they get a lot of it from eating vegetation and succulents that grow on the island. Now, something to keep in mind is that in Australia, their seasons are reversed from ours.

Christian: Sure.

Ellen: So their summer occurs from December to February. Whereas for us in the United States, our summer is typically from May to August. Well, we live in Florida, so ours is from March to the next March. Ours is forever. It's just summer and that's it. Unfortunately, a lot of quokkas actually end up not surviving the summer, but the ones that do are able to very efficiently reproduce to maintain their population numbers.

Christian: I guess they have to, huh?

Ellen: Yeah. So it's kind of a harsh environment that they live in, but they've kind of adapted to take advantage of it. Yeah. So moving on to ingenuity, these are behavioral adaptations that the animal has made that just kind of make it a little bit clever at solving the problems that it faces on a daily basis. So, I gave the quokka 7 out of 10 for ingenuity. Quokkas are mostly nocturnal. During the day, they like to hide in really dense bushes and kind of underbrush, and inside that thick vegetation, they actually make their own hidden trails. So they have little paths and trails that they've made for themselves that they use for quick escapes or efficient paths to food sources. Yeah. So they have a little tunnel system, almost. It's not underground or anything. It's usually just like, under like thickets and stuff. But they have little tunnels that they make for themselves. They typically live together in groups. In the mainland, these groups are pretty small and they're mostly just little family units. But on the Rottnest Island, the groups can be really large. There's groups of like up to 150 of these things.

Christian: Wow.

Ellen: Running around together as like a big fam. So, during the summer when food and water are low, quokkas have been observed expanding their diet to become more omnivorous. So they're normally just herbivores. They just eat plants, succulents, stuff like that. But sometimes if it's really, really dry and they don't have a lot of food opportunities, they'll start to eat small animals like snails and lizards.

Christian: Oh wow.

Ellen: Even though they're not really meant to do that, they will do it sometimes. So, you know, a little bit of an opportunist there. Quokkas are very trusting of humans, and large numbers of them can be found in the more developed area of the island. They- it's called the Settlement. So this island is kind of divided up into these different like biomes, and you can find a lot of quokkas in the more urban area of the island because food and water are more likely to be found there. So quokkas like to hang out there. So they kind of, you know, they've kind of figured out where they're going to get a better selection of nutrition and they like to hang out around there. There is part of this island that are these really like dry scrub lands, and occasionally those areas will have these brush fires where there'll be like a big fire, a bunch of it will burn down, and then after that there will be these periods of new growth. So quokkas will kind of prefer those areas during the post-fire growth period. So you'll see, whenever there's like a big fire in that area quokkas will kind of move in afterwards and then enjoy that more rich nutrition. And then once things kind of even out, they'll move on and go to find more like swampy areas that they like to hang out in.

Christian: Oh cool.

Ellen: Yeah. So they're, they're kind of, um... I gave them some ingenuity points for being clever about like relocating themselves to give themselves like better advantages. I dunno. I thought that was pretty cool.

Christian: Yeah, for sure. And then I bet the plants that grow after the fires are also pretty tender since they're new and budding and...

Ellen: Some good dank leaves out there.

Christian: And then they're like, oh, it's all gone. Time to go to the wet place.

Ellen: Yeah. So I dunno. I mean 7 out of 10, they're pretty good.

Christian: Yeah.

Ellen: Kinda... Kinda clever little critters. Now, aesthetics. This is what you guys want to hear about for the quokka. 9 out of 10. So quokkas are famous for their naturally photogenic smile. They have- they're not expressing anything. That's just the way their face is.

Christian: Sure.

Ellen: They have a resting happy face. It's just, it's so cute. Their little mouth is like turned up in this really cute little smile, they have really big round eyes, they have round, fluffy ears and these really big, fluffy, chubby cheeks, and it just makes them really cute. On top of that, they're also pretty friendly and they're not really very afraid of humans. So their adorable appearance and their friendly demeanor has made them one of the most popular tourist attractions on Rottnest Island.

Christian: Okay!

Ellen: They're kind of the island's claim to fame. This has inspired the social media trend of quokkas selfies that you've probably seen.

Christian: Hmm.

Ellen: This is like, the bulk of the reason people have asked us to talk about them is because of these quokka selfie threads. So some particularly noteworthy examples are from Chris Hemsworth and Margot Robbie, two Australian celebrities that have taken quokka selfies and put them up on their social media. Chris Hemsworth being Thor.

Christian: Yeah, I guess I didn't realize he was Australian.

Ellen: And then Margot Robbie being Harley Quinn from the Suicide Squad movie?

Christian: I didn't see it.

Ellen: Me neither. Anyway, so yeah, so these celebrity quokkas selfies and then just kind of the ensuing like... Everyone who goes to this island posts their quokka selfies have been really great for the visibility of the quokka and of Rottnest Island in general. It's like nobody knew about them before, and then all of a sudden these selfies got really, really popular. And then, you know, went like viral on social media and now everybody knows about them. So they've been really, really good for, you know, generating a lot of tourism and a lot of revenue for the island.

Ellen: Now it is super important to follow the directions of local authorities when it comes to interacting with not just this wildlife but any wildlife in general that you come across. So people trying to get selfies with quokkas will unfortunately sometimes try to tempt them with offerings of food. Uh, don't do that. That can be very unhealthy for the quokka, especially if it is junk food. It can be super bad for them. Do not do that. So although it might be really, really tempting, the penalty for touching or feeding a quokka is $150.

Christian: Wow... Is that US dollars?

Ellen: It's Australian dollars.

Christian: Oh, okay.

Ellen: Don't just go running around petting these little dudes cause there's a $150 fine for it.

Christian: Yeah. So, I'm guessing when they get these selfies, it's a no-touch selfie?

Ellen: Do not touch.

Christian: Gotcha.

Ellen: Yeah. There's actually a fair amount of controversy around quokka selfies. So particularly Instagram issues a warning that displays when you search for the hashtag "#quokkaselfie." I tested this, like I saw an article about it on the Internet and then I tested it on my own Instagram to be sure, and it really does happen. If you go to Instagram and you search the hashtag "#quokkaselfie", a warning screen comes up and it says: "You are searching for a hashtag that may be associated with posts that encourage harmful behavior to animals or the environment."

Christian: Wow!

Ellen: Yeah. It also gives a link to Instagram's wildlife exploitation guidelines, which I will say this, they have some really good, really valid points about illegal trade and have really good warnings about things like potentially sketchy practices, especially like paid photo opportunities with super endangered animals. Always, always, always be super wary of that stuff, but actually Rottnest Island Authority has publicly spoken against this notice. They object to it. They object to this notice being displayed for the #quokkaselfie hashtag. They said, and this is a quote from the spokesman for the Rottnest Island Authority, "It does not serve to educate or inform the public about our conservation efforts, or direct people to how they might develop a better understanding of this native species." So there's some beef there. Yeah. Instagram and the Rottnest Island Authority have some... Feud.

Christian: Well I guess, you know, it's a common problem with other animals, especially animals that are typically found to be cute but not so friendly and also more dangerous.

Ellen: Yeah. So you know, quokkas can be very easily startled. You could spook them very easily and make them drop their baby. But like... Yes, it is true that like it's very bad for people to try to, for example, feed junk food to quokkas to get them to pose for a selfie, like I get what Instagram is going for. I think that it is a good thing for them to be conscientious of how their platform is being used, especially when it comes to, you know, wildlife exploitation. I think this is one of those cases where they might want to tweak the wording of the notice because it can kind of raise some hairs to say like, "oh, this might be animal abuse" when people are just like taking pictures of wildlife without really disturbing them in any way.

Christian: I'd be interested to hear the other side of the story too though. Cause I imagine that is a common reaction to that even when maybe not so black and white.

Ellen: Yeah, I think it's a very interesting discussion because, I don't know, I kind of agree with both sides. It's, it's kinda tough. It's a tough one. But I thought it was really interesting to see that sort of back and forth.

Christian: Yeah.

Ellen: So yeah, that's my 9 out of 10 for aesthetics. They are so cute that it has caused a sort of an international feud.

Christian: Controversially cute.

Ellen: They are controversially cute. Yes. So, adorable little friends. So I will wrap up by giving you some final miscellaneous information about the quokka. Their conservation status is listed as vulnerable. So they are threatened, like I said earlier, by predation by feral populations of invasive predators, like cats and foxes. These are European, you know, non-native species that have been brought in and they're kind of destroying everything as they tend to do when they are in places they don't belong. But they're also facing a lot of habitat loss due to, you know, forests in their areas being cleared out for things like agriculture, housing or logging. It seems like this is more of a problem in the mainland. But in Rottnest Island, all of the wildlife on that island is federally protected.

Christian: Very cool.

Ellen: Yeah. But they are still vulnerable. So, you know there are still things that you can do to help them out. And I really recommend checking out the Rottnest Island Authority's website cause they have so much good information on there. My last thing that I wanted to say about them, I thought this was really cool. I found this article from Scitech's science media website Particle and this article was titled "Quokka Cure Not Quackery"...

Christian: Oh my.

Ellen: By Kirsten Flint in August of 2017, and I'm not going to pull any direct quotes or anything, but just to summarize like what I read: there were quokkas that were kept in labs in like the fifties and sixties, and these quokkas started to experience muscular dystrophy and it was resulting from a vitamin E deficiency. So it had been thought, up until that point that muscle fibers were completely just not capable of regenerating. Like once you're paralyzed, you're paralyzed forever. But, after the quokkas were documented completely recovering from paralysis once their vitamin deficiencies were corrected, this sparked this huge like, rush of research into possible treatments for muscular dystrophy in humans. So there's this big spike in research, you know, once people were like, "oh my gosh, it turns out muscle fibers actually can heal," then that just kind of like changed the game for muscular dystrophy research.

Christian: Well I think that would have also been the middle of the polio epidemic as well.

Ellen: I think so.

Christian: Um, so that, that makes sense that there was a big interest in that.

Ellen: Yeah. I'm sorry, I'm not a huge history buff or anything like that. I just thought it was really interesting that like, this pretty relatively unknown little like... Funky little marsupial had a really, really big impact in like medical research history. I thought that was pretty cool.

Christian: Yeah, for sure.

Ellen: So they've kind of impacted human history in their own adorable little way. So yeah, that is the quokka.

Christian: Well, thank you honey.

Ellen: You're welcome. Before we move on, I want to thank our patrons on Patreon! These- there are some people out there who are throwing us a couple bucks a month to help us grow and get bigger and better and get cooler. They were able to help us launch our website, which was really neat. Patrons get access to some really cool extra stuff like a feed of the show without ads, a patron-only discord server, and I just added, actually, I'm going to be sending out monthly photography prints to our patrons at various levels. So, you know, go, go check that out and consider pledging a couple dollars to support us and help us get bigger and better. For this week's episode. I want to thank our patrons, Brianna Feinberg and Krystina Sanders. So thank you guys.

Christian: Thank you. And those prints are very pretty. I can personally attest to them.

Ellen: You're biased.

Christian: Maybe. It doesn't mean I'm wrong though.

Ellen: I should mention that they're prints of photos that I took, they're not just like prints I like... Got off Google or something.

Christian: Here you go.

Ellen: Hope these aren't copyrighted!

Christian: Here's some stock images commonly used in memes!

Ellen: What if I sent them out and like, they all had like Getty images watermarked on them.

Christian: Just straight up memes, like, "guess I'll die."

Ellen: I'm going to actually start printing out memes on printer paper and sending them in the mail to our patrons, and signing them.

Christian: You can use that, um, that terrible quality paper I bought like five years ago. We still have,

Ellen: Yeah, I'll be sure to do that. So patrons, you're really getting your money's worth out of that. Anyway... Christian, it's your turn. You have another crowd-pleaser for us, don't you?

Christian: Yes, I do. So for this week I've got another animal that had lots of requests and that is the peacock mantis shrimp. So I chose the peacock mantis shrimp as a specific species, but a lot of people just know it as the mantis shrimp and it was suggested as such by Kyle Rauch, Michael Solon, Nicholas Kight, and Susanna Lewis at the Thornvale podcast, on Twitter as @KeeperSusannah.

Ellen: Thank you all.

Christian: Yes, thank you. So as I said, the peacock mantis shrimp is the specific species that I'm going with. Its scientific name is Odontodactylus scyllarus.

Ellen: Oh, I thought you were done after the first one. There was more.

Christian: I wish I was. It's a mouthful. My sources are coming from oceana.org, the National Aquarium website aqua.org, which is in Baltimore, Maryland, by the way.

Ellen: Oh wow.

Christian: Yup. And animaldiversity.org. Now, I know what you're thinking.

Ellen: Do you?

Christian: But Christian, The Oatmeal has talked about the mantis shrimp many a time.

Ellen: Oh, see, I was thinking about the RadioLab episode.

Christian: Oh, that too. It's a popular animal.

Ellen: I feel like the Radiolab episode came first.

Christian: Maybe.

Ellen: I think it was. I think that was what like sparked public interest in the Mantis shrimp.

Christian: For me, it's more of the visual cue of the Oatmeal stuff.

Ellen: Oh, yeah. Sure.

Christian: But yeah, a very interesting animal. So this particular species, its adult size is between 2 and 7 inches, or approximately 5 and 18 centimeters long.

Ellen: It's like the talon of a chicken.

Christian: It's bigger than that.

Ellen: The toe of a chicken?

Christian: It's like a small lobster.

Ellen: I thought you said two inches.

Christian: Two to seven inches.

Ellen: Two inches is like the toe of a chicken.

Christian: ...No way. I mean, yeah, at its smallest. I'm not- I'm going to start talking about chickens now. And these little dudes can be found in the warm waters of the Indian and Pacific oceans. They belong to the taxonomic family... Uh, another big word.

Ellen: Okay, let's go.

Christian: Odontodactylidae.

Ellen: Oh- hold on. Odontodactylidae.

Christian: Yes.

Ellen: What! That's every consonant in the entire English language.

Christian: It's so many. Uh, the other things in that family are the other mantis shrimp, of which there are approximately 400 different species of.

Ellen: Y'all gotta be more specific with your species requests PLEASE.

Christian: So I chose the peacock one because it's pretty, and that's that.

Ellen: Excellent. That's also how I make choices of things.

Christian: Effectiveness: So I'm going to give it a full 10 out of 10 nice. My first and biggest point is they have the hands that no one wants to catch. The hands with a swiftness! But they aren't really hands. So they have these little hard clubs that are also called raptorial appendages.

Ellen: I'm sorry. Raptorial?

Christian: Yes. I guess the adjective form of raptor.

Ellen: I didn't know that raptor had an adjective form.

Christian: Yes.

Ellen: I... That's incredible. That's a very powerful word.

Christian: Yes. So they have these little club-like appendages. Think of them as being their first set of legs, are these little appendages.

Ellen: They're boxing gloves?

Christian: Kind of look like that. So they're calcified claws basically, and they use them to deal massive amounts of bludgeoning damage, in D&D terms.

Ellen: Like 2d8 bludgeoning damage.

Christian: 2d12 is more like. But and they're strong. So what they're meant to do is to break through the shells of things like clams, oysters, other crabs and lobsters, that kind of thing.

Ellen: Wow.

Christian: Yup. The larger specimens have actually been known to damage the glass and aquariums with this, with these strikes.

Ellen: Incredible.

Christian: They're very, very strong.

Ellen: This is probably why I have not seen one in an aquarium.

Christian: Supposedly some do, just like the National Aquarium actually, which is why I'm pulling information from them. So if we ever find ourselves in that part of the country, maybe we can check it out. But their strike travels around 20 meters per second. That's fast. Very fast.

Ellen: Do you happen to have an imperial conversion for that?

Christian: I don't. I won't....

Ellen: Please?

Christian: And I shon't. I Dunno. Like 60 feet per second?

Ellen: What did you say the number was?

Christian: 20 meters per second.

Ellen: *googling* 20 meters per second...

Christian: But that's like what? A hundred feet per...

Ellen: 45 miles per hour.

Christian: You missed my joke.

Ellen: Was it good?

Christian: Yeah.

Ellen: What was it?

Christian: I said, so that's what a hundred feet per football game?

Ellen: Okay, well it's 45 miles per hour.

Christian: Is that right?

Ellen: 20 meters per second. 20 meters per second equals 45 miles per hour. Google says it right here!

Christian: Okay, that makes a little sense I suppose because a lot of sources will say, oh, this is as fast as a 22 caliber bullet, which is not right. It is the same amount of force as a 22 caliber bullet.

Ellen: Oh, okay.

Christian: But the speed of a bullet is more than 10 times faster than that. Oh, okay. So I think that just might be a little confusion here and there.

Ellen: Either way, you don't want get hit by one.

Christian: Yes. And now, part of the reason that all that force is in addition to the initial strike, that strike is also creating what's called a cavitation bubble of air.

Ellen: Cavitation?

Christian: Yes. So that strike is transferring so much kinetic energy that it causes a bubble in the water. And as that bubble implodes on itself, or collapses on itself, it creates heat, light, and sound.

Ellen: What?

Christian: Yes.

Ellen: So it's also doing radiant damage.

Christian: Aw, these things are like paladins. But yes, tough little dudes.

Ellen: This is like when you uh, are playing a Skyrim save and you max out your melee skill

Christian: Gloves of the pugilist or however that's pronounced. And then, the way they hold their claws, they're kind of folded out in front of them. It's very much like the mantis insect, like the praying mantis.

Ellen: That's probably where they got their name.

Christian: Yep. So that's where that part of the name comes from. And then, the peacock part of this one is because of how pretty it is. I'll get to that shortly.

Ellen: We have a whole section for that.

Christian: Yes. The next effective thing that I'm giving them points for, their vision. So this is another thing that has been talked about a lot.

Ellen: Let's hear it again, Christians.

Christian: Yes. So they have incredible vision. They can see colors in wavelength that we cannot, examples being ultraviolet and polarized light. So part of the reason for this is because their compound eyes have 16 types of color receptive cones, whereas most humans only have three. I say most because some have four, and there's a whole other RadioLab podcast about that ability.

Ellen: Yeah, check out the radio lab episode colors for more information on...

Christian: Those might be in the same episode.

Ellen: Yeah, it's the one episode where they talk about mantis shrimps, and cause they talk about other animals with different numbers of receptors in their eyes. So yeah, if you haven't heard it yet, check out the RadioLab episode tellers for a deep dive into like photoreceptive- an explanation on photo receptive cells in your eyes and stuff. It's really cool.

Christian: So what this basically translates to is the more different kinds of these you have, and if they're sensitive to different frequencies of light, it gives you a better ability to distinguish between different colors. And also in the mantis shrimp case, they can see beyond the, what we know as the visual spectrum. So, you know, ultraviolet, being part of that, we cannot see older violet light directly. And it turns out they look even cooler when you see them the way another mantis shrimp would.

Ellen: Oh really?

Christian: Yeah. So just with our eyesight, their colors are very vivid and interesting. But with the eyes of another mantis shrimp, it's even better.

Ellen: What would elf eyes see?

Christian: They're taking the crustaceans to Isengard!

Ellen: No.

Christian: No? Okay.

Ellen: I regret setting you up for that.

Christian: Well, then I just spiked it into the ground.

Ellen: Not unlike a quokka spiking its baby.

Christian: Womp. So that was a 10 out of 10 for effectiveness.

Ellen: Perfect score, nicely done. Slam dunk.

Christian: Yep. Ingenuity: I'm giving them I guess a modest 7 out of 10 for ingenuity.

Ellen: Really?

Christian: Yeah.

Ellen: That's a lot for a shrimp.

Christian: Well, so they, they dig these interesting tunnels that are kind of U-shaped. They spend most of their time there, they hang out when they're not actively doing anything else it seems. They'll breed there, they'll, they'll raise their young there...

Ellen: I also hang out in a cave when I'm not doing anything else.

Christian: And I just thought it was interesting that they know that they have the ability to break open the shells of other creatures. Like, "I have these powerful hands" just start breaking open to other animals to get at their yummy, gooey parts.

Ellen: I wonder how much of that is trial and error. I wonder if they ever like run up on like, a shark or something and be like, "yeah, surely I can take this."

Christian: I mean, the way I think of it, the first one was probably like... Two different crustaceans. One was like, "hey Mike, shake my hand!" "Okay, here you go- Oh God!"

Ellen: Yeah. That's probably how that went down.

Christian: "Your hand is gone!"

Ellen: Or maybe he was just trying to like, greet his, uh, like hermit crab buddy...

Christian: By knocking on the door, that is his shell.

Ellen: Yeah. And he went to knock on the door of his house and then just...

Christian: No more door. Uh, that's all I have for ingenuity.

Ellen: This poor mantis shrimp can't make any friends!

Christian: He's too powerful and too beautiful.

Ellen: Too strong. It's the Dragon Ball Z curse

Christian: Speaking of beauty, aesthetics. 10 out of 10. They're very pretty and they have stunning colors. They're very, it's just almost iridescent and is just... You really have to see it. And in particular it's the males that have the coloration that's most interesting. And it has lots of greens and blues and reds.

Ellen: Ain't that always the way it goes?

Christian: Yeah. I mean, the females are mostly red. Still pretty though.

Ellen: How come the dudes are always the fabulous ones?

Christian: It's just like peacock. Right? And then also the eyes themselves, they look very interesting. I'm not going to try to describe them through voice, but I do highly recommend to check them out to see what the eyes themselves look like.

Ellen: Is it the color or the shape of them or?

Christian: The anatomy itself. Cause they're compound eyes, not unlike many insects.

Ellen: Those always look really cool, cause they always have interesting geometric patterns to them.

Christian: Yeah, and they have distinct parts. So they have horizontal bands that go through the middle. It kind of looks like they have several pupils that are kind of moving around too.

Ellen: Hmmm. Interesting.

Christian: Yeah. A little miscellaneous info about our friends: their conservation status is insufficient data.

Ellen: Oh!

Christian: Yeah. We don't know. I mean it's thought that they could be vulnerable to destruction of coral reef habitats, cause that's where they're primarily found. Other than that, no real data there.

Ellen: Okay. Well, hope for the best.

Christian: Yeah.

Ellen: Fingers crossed for the mantis shrimp. Hope they're doing good.

Christian: Yeah. And they are pretty valued by aquarium collectors. Some, I should say. So like I said, they're very beautiful to look at but the negatives are, you know, one: when they're bigger they could damage the tank.

Ellen: Yeah. You need a bulletproof tank, huh.

Christian: But also they have a tendency to eat anything else that's in the tank. So...

Ellen: Who's gonna step to them?

Christian: Just stay out of reach, I guess.

Ellen: Nobody can keep them in check. Like you can't have fish cop coming in there, like trying to keep everyone in line!

Christian: Even another mantis shrimp. They're pretty territorial. They try to crack each other's tails open, and it turns out that that part of their shell is the thickest part because of that.

Ellen: For that exact reason. They've evolved like, bulletproof Kevlar tails.

Christian: An evolutionary arms race.

Ellen: Well, I gotta say they're winning.

Christian: And they're actually kind of known that if you have tanks that have living coral in it, they are known to like basically think, "I want to dig a tunnel through this," punch, punch, punch, punch, punch. Now this coral has a big hole in it.

Ellen: Jerks! That's rude! Leave the coral alone

Christian: Yeah. And then I'm going to wrap up with what they do with their eggs. I think it's nice. So when the eggs are laid, the female kind of holds them on her "person," for the lack of a better term. Just kind of holding them in and they're also like adhered to their body.

Ellen: Oh, interesting. So she's keeping them close.

Christian: Yeah. So she holds onto them and cleans them until they're hatched.

Ellen: That's kinda cute! She cleans her little eggs.

Christian: She doesn't eat during this period.

Ellen: Oh...

Christian: Yeah.

Ellen: She's a much better mother than the quokka. The quokka mom was like, "BYE!"

Christian: Okay, but... If it wanted to, it could use them like bullets. Cause there's just so many.

Ellen: WHAT. No, it couldn't. You made that up.

Christian: That's true. They don't really have any digits to grab that kind of thing with. But it'd be funny.

Ellen: That's a funny visual. Now you mentioned that they're supremely powerful.

Christian: Yes.

Ellen: They have incredible detection capabilities.

Christian: Yes.

Ellen: And they're supremely stylish. Is this an anime villain?

Christian: Uh, if you're a mollusk.

Ellen: Mantis shrimp confirmed anime antagonist. You know this to be true.

Christian: Jojo!

Ellen: Jotaro!!

Christian: That's the peacock mantis shrimp.

Ellen: Thank you, my love. That was delightful.

Christian: It was enjoyable for me as well.

Ellen: I'm glad. That was really good. I had heard it talked about but not by you.

Christian: I might have mentioned it once or twice in passing.

Ellen: Alright, well those are our animals segments. I want to wrap up the show with our relatively new audience response segment. Only had one that I wanted to share this week. So last week we talked about the giant manta ray, and in response to that segment, our friend Jacob Jones shared his experience with giant manta rays in the wild. So our friend Jacob works in commercial fishing, he works on a shrimp boat and he had this to say about giant manta rays: he says, "I've caught two giant mantas in the last seven years. With shrimping, we use large nets that go to the ocean floor, and inside of the nets there is a large grid called a turtle extraction device, or a T.E.D., That lets the larger things escape, like most sport fish, sharks, dolphins, turtles, etc. But the giant mantas are too heckin big and can't make it to this part of the net, because they taper down from a 68 foot circumference, or 34 on the first boat I worked on, down to like a four foot circumference as they go to the bags where the catch is held. So when we pick up and pull the bags in, we will see them flapping irately in the nets until they slide out." So I was concerned and I asked if the manta rays are able to get out safely once the net is pulled up, and Jacob said, "Yeah, they slide right out. They don't seem to have any issues as they flap on the surface for a moment as if cussing at us, and then they swim off. I have never once seen one get wounded from being in the net. Just annoyed that we interrupted their swim."

Christian: Angery sea blanket! But yeah, I really appreciate that. Thank you Jacob.

Ellen: Yeah, I thought that was really cool because I've definitely never seen a manta ray in the wild, but it must be really interesting to get a chance to see so many really cool ocean species out in their native habitat. Jacob also mentioned that they had caught a basket star and I thought that was really cool.

Christian: Yeah. So I had actually, I saw this on Facebook and I did a little research on the T.E.D. Device. So they are purposely meant for sea turtles, right? Because you know, the difference between the manta rays and the sea turtle is that the sea turtle eventually needs to get air from the surface. So the manta is probably okay because it's, even if it doesn't get all the way through, it's still having water pass over its gills, it's going to be okay, whereas a sea turtle, it will eventually drown. Right?

Ellen: Sure.

Christian: And then, I've read that even sometimes, not all of these devices work because there are turtles that get too big for that.

Ellen: Oh no.

Christian: Like the uh, the loggerhead turtle.

Ellen: Oh, like, yeah- Oh, those are big.

Christian: Yeah.

Ellen: Yeah, so I thought that was really neat, to some firsthand experience of an encounter with giant manta rays and the visual of them being quite perturbed by being caught in a net, I thought was kind of funny.

Christian: I've heard them described by people who have seen them out in the ocean is that they look like a large quilt just kind of floating through the water.

Ellen: That makes sense. I mean they do have that like, square shape. I thought that was pretty cool. So thank you for sharing your experience, Jacob.

Christian: Yeah, thanks!

Ellen: All right, so that's our show. We're all done. We're going to wrap up with a few final notes. I want to thank everybody who has been listening and everybody who's been recommending us to your friends, you guys are the best and I love you and thank you, especially, to people who have been leaving reviews on your podcatchers. That means a lot to us and it helps us out a lot. Hopefully we've earned a good review from you, so if you feel so inclined, please drop us a drop a little five star rating on there.

Christian: Yeah. Plus it makes us feel good!

Ellen: It makes me really happy. You know I thrive on validation and I live for it. So, you know...

Christian: Can I review it?

Ellen: Yeah, let's hear it. Let's hear your review of the show that we're doing right now.

Christian: ...Oh man.

Ellen: The pressure's on.

Christian: Ellen is awesome. The other person, [some dumb inaudible noise because Christian's a mean jerk]... I don't know. I don't know how to translate that to text, but...

Ellen: Well, I guess I'm going to have to do it when I'm doing the transcript, won't I?

Christian: Dear Future Ellen, I'm so sorry.

Ellen: You're not sorry, because you keep saying you are, and you keep doing it anyway. The best apology is changed behavior, Christian Weatherford. Anyway, you can connect with us on Facebook, Twitter, or Instagram by searching the title of the show. You can also find our official website at www.justthezooofus.com, if you have an animal species you want to hear us review, you can submit that to us either on social media or just via email at Ellen@justthezooofus.com.

Christian: Yes.

Christian: Transcripts of this episode and others will be going live on our website as soon as I can get through them. They take a very long time, please be patient with me. And as our final note, I want to thank Louie Zong for the use of his song "Adventuring" off of the album Bee Sides.

Christian: It's good stuff.

Christian: We love it.

Christian: Merch store.

Ellen: Merch store? Oh! Yeah, gosh, yeah. I put some designs up that you can buy and put on things that you wear.

Christian: And drink from, right?

Ellen: And drink from! Yes, there's like coffee mugs on there. I think there's also a reusable cotton tote.

Christian: Everyday items you interact with, with our brand on it!

Ellen: You can add them to your inventory and use them for functions. They're functional, and they have our little cover out on them. I'm also working on some other little designs that I think would make cute merch, so... I'm working on it. So yeah, that's our show.

Christian: Thanks everyone!

Ellen: Thanks. We love you.

Christian: Especially me.

Ellen: Bye.

Christian: Bye!
