[Music] to another episode of the scishow talk show today we are joined by Emily graslie the host of the brain scoop I always sort of dread your appearances on the show because I am always super confused also I hate you oh I'm sorry I liked it when I said dread seemed so sad but it is not because of you I promise it is because I have no I never have any idea I can't see the bones the way you see the bones well our one of our visitors for later crawling around anyway I'm super excited to be here and I hope it's not gonna be too painful because I'm super excited about this specimen here okay we're gonna try and stop Hank it's possibly my favorite specimen in the museum and I know I say that about Wow look at this can you sing this stuff Hank theme song what is this something things I don't know weird today we're gonna stomp pink yay that's good this has weird teeth yeah it has super weird teeth feel them whoa dark super sharp that makes me think that they continuously grow yes that's it that's a great observation they do these ones are also super sharp so all of its teeth continuously grow yeah that's weird that's not normal what do you think it eats I don't I don't something hard kind of something hard to digest oh but it's not hard well I was thinking like big tree matter yeah yeah that's hard yeah well I closed it loose those kind of fibrous things okay I'm totally giving it away you're totally giving it away you're not totally giving it away you always think you're giving me hinges no there's so many animals Emily it is fairly large is it a is it is it does it swim yes it's very good at swimming surprisingly is it oh god I know what it is I think no I don't think I do because you said surprisingly yeah I thought it was what are they one of those things that I like beavers but they're small muskrat no it's not a muskrat that's right this is this lives in a tropical region I'll give that hint to you does it have a I've ever lived in a place where it lives I said live in America um South Amer okay okay okay so do I know do I know what this thing is called yes yes I'm sure you've seen adorable videos of them on the Internet is it an otter no that's all the adorable videos I watch our otters okay so it lives in a tropical area yeah it is surprisingly good at swimming because otherwise it's not very good at moving it's a bad land Walker yeah terrible moves that a staggering six and a half feet a minute is it a sloth yes why look how crazy its teeth are you in is Loffler oh yeah cute I would not have gotten super sharp yeah yeah but they're just gonna bite you very slow yeah yeah it has to have an incredibly sharp teeth because of its diet they don't the things that they kind of eat don't offer them any energy so it's eating all this plant material and basically that just sits in its guts for weeks at a time it comes down to the ground to defecate about once a week and it takes a very long time to do so that's the only time they ever go to the ground they do everything hanging upside down if they eat they sleep they give birth they mate sometimes I'll even die clutching onto a branch and they'll just hang there after they're dead because they're just hanging out there they dislike moving so much that their digits have fused together so like literally they can't move it's two fingers apart it just yeah so you said it's a good swimmer yeah I did not know that about sloths yeah yeah because they aren't very good at crawling on land their arms are too long how do they even end up in the water well I guess if they're evading creatures or if they're trying to expand their habitats like the average geographical range of a sloth is one or two trees you know they have to move away from home eventually and they're not very good at walking so they'll find like a little channel and look at in the water another one of my favorite things about sloths and I have to share this is that they have symbiotic relationships with certain species of algae so there are certain kinds of algae that grow on sloths that are only found in the fur of sloths it's so the hold that the only place that this kind of algae exists is in its fur it's fascinating that's really weird yeah also that they just have algae growing on them well that's how they move yeah it's hot because they move slowly and their fur is a really good insulator against the rainy season so then the algae will start to grow on them it works as a camouflage it's a great relationship and then the algae Foster's all kinds of little parasites that help keep them clean and there are whole colonies of moss and insects that live on sloth good now we're going to be joined by something that isn't this law yes but it is also adorable yeah I'm also super excited about this what do we have here cavy the best thing I've ever seen this is the third largest rodent in the world you're a big rodent and a lot of people think he looks like a kangaroo and that's kind of like the way I'm holding him but I'm gonna go ahead and set him on the table here Wow you can see that yeah he stands like a deer so he stands on all four oh you're like a deer bunny oh I would I would like some table what's this okay no tablecloth is my favorite treat so cute look at those eyes that is an adorable animal so we actually have his skull here well it's not his skull it's not so he's a rodent so I guess the third largest rodent in the world and rodents are our rodents because of these teeth that they have an ever-growing incisors - on the top and two on the bottom and they're gonna use those to chisel their food like that and they have no teeth in the middle I mean I can yeah yeah just - just just four teeth total yeah well and then they have all these moments back there so that's what he's doing right now so he's crunchy with the front and now right now he's grinding it back with those very strong jaw muscles that you have cool ears here's actually he is pretty friendly you can actually feel those ears if you'd like they're hard yeah they're not soft like a rabbit would yeah and so they can't actually move those ears different directions like a rabbit can they just stay that those directions is hairy but you're you're the one that's making it hairy buddy you are covered in hair so South America South America yeah so Patagonia Argentina very tips they live in the grasslands at the forests there and they're gonna leave in herds and so they are they're like they're like deer yeah but they have a different a little bit of a different hierarchy or system I guess social system they actually are monogamous they pair for life oh they live about well I'm not very long in the wild maybe four to five years in the wild but they can live about 15 years in captivity so they're gonna be monogamous Nate for life and they're gonna have but they're gonna have a bunch of pairs together so they're gonna live in a herd so one pair is going to sit and watch all the babies now they make this big hole so like rabbits they live in a burrows called a Krrish and then down that hole they all keep their babies down there but they've met females won't feed each other's feed babies they only feed their own so one will crawl down there and feed the babies so one pair is gonna keep watch I guess over the den while all the other ones go off and eat and then one pair is gonna come back and they're gonna switch patrol I guess when you say heard I think of that scene in the lion king when the wildebeest come over the cliff and like I know I'm imagining a herd of cavies and I could would just be so adorable I'd be like oh you could Stampede me they are herbivores so they only eat while he's eating some Apple right now but in the wild they eat mostly grasses different kinds of grasses so he's a he's a Patagonian cavy now there's a couple different animals in the cabbie family there's the capybara which is the largest rodent in the world and there's also another very common animal for a cab in the cabbie family and we actually have his best friend here his name is patches and so they like to have like you would like to have chili pepper having company their play dates they live together Oh roomies so we can go ahead and bring patches on over here Oh what I I can see why you got badges cavi is four toes in the front so you're monogamous pair these two are two boys they're best buds but guinea pigs actually you wouldn't find one of these guys in the wild I mean obviously the coloration wouldn't help him very much they're gonna be about the same color as chili pepper here to blend in and they're gonna be a little bit smaller so people have red pepper I'm gonna go ahead and pick you up people have domesticated the guinea pig and they've domesticated it for interesting reason just like we've domesticated chickens they domesticated guinea pigs for food have done that are you don't do that into the microphone and she'll never actually heat the Caddy's talk like that - they do those little whistles and grants and growls and things like that he also purrs turning pepper and patches thank you
