I’m your host, Kate Shaw. This week we have suggestions from Henry and Miranda, so we’re going to learn about some weird but cute frogs! First, Miranda listened to episode 270 about the tapir frog and commented about a little frog native to Puerto Rico that sounds very similar. It’s call the coquí frog and it has an adorable beep! It sounds like this: [frogs beeping] You can definitely hear why the coquí frog is called that. It sounds like it’s saying “coquí.” The coquí is a type of tree frog although most species prefer to live on or near the ground. Instead of webbed toes, their toes have discs that act sort of like suction cups that help them stick to leaves. Different species of coquí frogs are different colors, including brown, green, gray, and yellow. Their tummies are usually white or yellow. Most species are quite small, although a few species grow as big as 3 inches long, or about 8 cm. There are at least 17 species of coquí frog known in Puerto Rico, with more species found in other parts of the Caribbean and in Central and South America. New species are discovered from time to time, including the tiniest species, the Puerto Rican wetland frog. It was only discovered in 2005 and described in 2007. It’s about 15 mm long from nose to butt, or more properly snout to vent, and while males are bright yellow, females are browner. It lays its eggs on the leaves of a plant called the bulltongue arrowhead, and it only lays one to five eggs at a time. Instead of hatching into tadpoles, the eggs hatch into miniature frogs which are ready to hop out and eat lots of ticks, because that’s mainly what this species of coquí eats. And that’s about all we know about this particular species except that it only lives in one small area of Puerto Rico and is critically endangered. Another species of coquí is the golden coquí, which is almost as small as the Puerto Rican wetland frog. It’s yellow or golden in color, or sometimes a more olive green. Instead of laying eggs that hatch into tadpoles that develop into frogs, the golden coquí skips most of these steps and just gives birth to fully developed teeny baby frogs, three to six of them at a time. The golden coquí lives in a small, specific habitat, a moist subtropical forest where bromeliad plants grow. Bromeliads are shrubby plants with succulent-type leaves that retain water. Pineapples are a type of bromeliad, although not the ones the golden coquí lives in. Unfortunately, the golden coquí is also critically endangered and may actually be extinct. No one has seen one since 1981. Most species of coquí lay their eggs on leaves instead of in water. The eggs still need to stay moist, though, so in many species the male will bring water to the eggs. He does this by just dunking himself in water, then returning to the leaf where the eggs are and plunking himself down on the eggs. He will also guard the eggs from potential predators. The eggs of all coquí species hatch into frogs instead of tadpoles. A few species of coquí have been introduced to other parts of the world, either by accident or on purpose, and have become invasive species. This is especially true in Hawaii, where the coquí has become incredibly common and as a result is causing some native frogs to decline in numbers, along with other animals. But in Puerto Rico, where the coquí belongs, people are naturally proud of their loud little frogs. The indigenous people of Puerto Rico,

Thanks to Liesbet for this week's suggestion, about two mammals that have evolved to be hairless! Happy birthday this week to Declan and Shannon! The hairless bat has a doglike face and a doglike tail but (and this is important) it is not a dog [photos from this site]: The naked mole-rat's mouth is behind its teeth instead of the usual "my teeth are in my mouth" kind of thing: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we have a suggestion from Liesbet, who asked about furless animals. We’re going to learn about two mammals that don’t have fur, and they’re not ones you may be thinking of. But first, we have two birthday shout-outs! Happy birthday to Declan and Shannon! I hope both your birthdays are so amazing that whatever town you live in finishes off the day by giving you the key to the city. What do you do with the key? I don’t know, but it sounds like something to brag about. Mammals are famous for having hair, but not all mammals actually have hair. Cetaceans like whales and dolphins have lost all their hair during their evolution into marine animals, although before a baby whale is born it has a little bit of fuzzy hair on its head. Other mammals, like humans, pigs, walruses, and elephants, have evolved to only have a little hair. There are also domesticated mammals that have been bred to have no hair, like sphynx cats and Chinese crested dogs. There are other domesticated hairless mammals, though, including two types of guinea pig. The skinny pig only has a little bit of fuzzy hair on its face and ears, while the baldwin pig only has a tuft of hair on its nose. But the animals we’re going to talk about today are hairless animals you may not have heard of. For instance, the hairless bat, which lives in parts of Southeast Asia. Its dark gray body is almost completely hairless, although it does sometimes have little patches of fuzz on the head and tail, and longer bristles around the neck. It’s nocturnal and eats insects, but since it’s a fairly large bat, around 6 inches long, or 15 cm, it can eat fairly large insects. It especially likes grasshoppers, termites, and moths. The hairless bat roosts in colonies of up to a thousand individuals, and it lives in caves, hollow trees, or rock crevices. Although it uses echolocation, it doesn’t have a nose leaf like many microbats have, but instead has a little doglike snout. Its tail is skinny like a little dog’s tail instead of being connected to the hind legs or body by patagia. It has a little throat pouch that secretes strong-smelling oil. It also has a sort of pocket on either side of the body. Originally people thought that mother bats used these pouches to carry their babies, since hairless bats usually have two babies at a time. Instead, it turns out that mother bats leave their babies at home when they go out to hunt, and the pockets are used for something else. The pockets are formed by a fold of skin and the end of the wing fingers and membranes fit into them. The bat uses its hind feet to push the wings into the pockets, sort of like stuffing an umbrella into the little cover that it comes in when you first buy it. This allows the bat to run around on all fours without its wings getting in the way. Since most bats can’t walk on all fours at all, this is pretty amazing. Our other hairless animal today is the naked mole-rat, which is not a mole or a rat. It is a type of rodent but it’s more closely related to porcupines than to rats. It lives in tropical grasslands in parts of East Africa and spends almost its entire life underground. It lives in colonies of up to 300 individuals, and the colony’s tunnels and nesting burrows are extensive, often covering up to 3 miles, or 5 km. It eats roots of plants and the colony carefully only eats part of each root so that they don’t kill the plant. The roots continue to grow, providing the colony with lots of food.

Sign up for our mailing list! We also have t-shirts and mugs with our logo! Happy Halloween! Let's learn about some shapeshifters of folklore, including the werewolf and kitsune (thanks to Joel, Pranav, and Emma!), and a real-life shapeshifter. Don't forget the Kickstarter, as if I'd let you forget it: https://www.kickstarter.com/projects/kateshaw/beyond-bigfoot-and-nessie Further reading: Folklore and Mythology Breeding Butterflies Further listening: MonsterTalk (note: sometimes there's adult language or really scary themes) Sandman Stories Presents podcast A death's head hawkmoth, looking spooky: A death's head hawkmoth caterpillar, not looking spooky at all: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. It’s Halloween week and that means we need to talk about a truly spooky monster! Both Joel and Pranav suggested the werewolf a while back and Emily suggested the kitsune [kee-tsoo-neh], so let’s learn about shapeshifters and were-animals of all kinds. “Wer” is an Old English word that just means “man,” and just to get confusing, the word “man” used to refer to any person. The word “wif” referred to a woman, with wifman actually meaning woman. From those words we get the modern uses of wife, woman, and man, while “wer” is obsolete except in werewolf. Let me derail myself from talking about language by reminding you about our Kickstarter! It ends pretty soon, on November 5, 2021, so if you’ve been thinking about backing the project this would be a great time. It’s to help me publish a book all about mystery animals, called Beyond Bigfoot and Nessie: Lesser-Known Mystery Animals from Around the World. The book has a foreword by Blake Smith of MonsterTalk, the science show about monsters, and if you don’t already listen to that podcast, it’s a whole lot of fun and informative too. Thanks to everyone who has already backed the project! Now, Happy Halloween and on to the spookiness! The important first question we need to answer is if werewolves really exist. No. They do not exist outside of folklore and fiction, and I’ll explain why later so you don’t ever have to worry about werewolves or any other shapeshifters. But first, let’s learn what werewolves and kitsunes are. Werewolves are supposed to be people who can turn into wolves. Depending on the story, this can happen when the person wants to turn into a wolf or it can happen during the full moon whether the person wants to be a wolf or not. Sometimes the person has a magical wolfskin or some other item that they put on in order to transform. Sometimes they have to cast a magic spell, but sometimes it’s a curse that someone else has inflicted on them. Some stories say that the only way to kill a werewolf is by shooting it through the heart with a silver bullet, especially one that’s been blessed by a priest. The werewolf is mainly from European folklore, where for many centuries all werewolves were also supposed to be witches. Until about the 18th century in some areas, if someone accused you of being a werewolf, you could be put on trial as a witch. Lots of people were convicted of witchcraft and killed during waves of witch-hunts in various parts of Europe. Most of the people accused were women, especially elderly women, especially women who were widowed or single, especially women who owned land that someone else wanted. Hmm. The kitsune is a creature of Asian folklore, especially from Japan, that’s basically a fox that can work magic. It’s sometimes said that all foxes can turn into humans if they want, especially older foxes. The older and more powerful a kitsune is, the more tails it’s supposed to have, up to nine. Kitsunes sometimes play tricks on people but they can also act as guardians and friends. About the same time that old ladies were being accused of being werewolves in Europe, though, around the 15th to the 18th centuries, something similar happened in Japan.

This week we're examining the Tantanoola Tiger, a mystery animal that probably wasn't a tiger...but what was it? This episode is rated two ghosts out of five for monster month spookiness! Thanks to Kristie for sharing her photos of the Tantanoola tiger! Happy birthday to ME this week! I've decided to turn 25 again. That was a good year. Further reading: The Tasmanian tiger was hunted to extinction as a 'large predator'--but it was only half as heavy as we thought The grisly mystery of the murderous Tantanoola Tiger (Please note that the end of this article has some disturbing details not appropriate for younger readers.

The numbat is striped but too small to fit the description of the "tiger": Our friend the thylacine, probably not strong enough to kill a full-grown sheep: Tigers are really really really big. Also, don't get this close to a tiger: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This past spring, when I was researching mysterious accounts of big cats spotted in Australia for episode 274, I considered including the Tantanoola Tiger. That was Kristie and Jason’s episode, and Kristie casually mentioned that she’d seen the stuffed Tantanoola tiger on display and wasn’t impressed. She even sent me pictures, which we’ll get to in a moment. In the end, I decided the Tantanoola Tiger deserved its own episode, because it’s completely bonkers, and that it needed to be in monster month, because parts of the story are weird and creepy. I give it two ghosts out of five on our spookiness scale, so it’s not too spooky but it’s more than a little spooky. The story starts in the southeastern part of South Australia at the very end of the 19th century. The little town of Tantanoola was home to a lot of sheep farmers, and in the early 1890s something was killing and eating sheep. For years there had been rumors that a Bengal tiger had escaped from a traveling circus in 1884 and was living in the area, so once half-eaten sheep carcasses started turning up near Tantanoola, people assumed the tiger was to blame. There was definitely something unusual killing sheep. Aboriginal shearers reported seeing an animal they didn’t recognize, something that frightened their dogs. Paw prints were found that measured over 4 inches across, or 11 cm, which is really big for a dog’s print although that’s what it resembled. It also happens to be a reasonable size for a small tiger, although a big tiger’s paw is usually more like 6 inches across, or almost 16 cm. In 1892, a couple out driving in their buggy saw a striped animal cross the road ahead of them. They reported it as brown with stripes and a long tail. They estimated its length as three feet long not counting its tail, or about a meter, 5 feet long including the tail, or 1.5 meters. This is actually really short for a full-grown tiger. A big male Bengal tiger can grow more than ten feet long, or over 3 meters, including the tail, and even a small female Bengal tiger is about eight feet long, or 2.5 meters, including the tail. There aren’t a lot of animals native to Australia that have stripes. The numbat has stripes and does live reasonably close to Tantanoola, although it was driven to extinction in the area by the late 19th century. But the numbat is only about 18 inches long, or 45 cm, including its tail, and it looks kind of like a squirrel. It eats insects, especially termites, which it licks up with a long, sticky tongue like a tiny anteater. It’s even sometimes called the banded anteater even though it’s a marsupial and not related to anteaters at all. Plus, it doesn’t eat very many ants. The female numbat doesn’t have a pouch, but while her babies are attached to her teats they’...

Thanks to Pranav for this week's suggestion, lobsters! Happy birthday to Jake!! Visit Dr. Oné R. Pagán's site for links to his podcast and his free book Arrow: The Lucky Planarian! You can also order his other books from your favorite book store. Here's the direct link to his interview with me!

I’m your host, Kate Shaw. As invertebrate August continues, this week we’re going to talk about lobsters. Thanks to Pranav for the suggestion! But first, we have a birthday shout-out! A great big happy birthday this week to Jake! I hope your birthday is epic fun! I’d also like to let you know that Dr. Oné R Pagán interviewed me recently about my book, Beyond Bigfoot & Nessie: Lesser-Known Mystery Animals from Around the World, and you can hear that interview on his podcast, the Baldscientist Podcast. Baldscientist is all one word. I’ll put a link in the show notes. While you’re at it, you should definitely buy his books, including his latest one, Drunk Flies and Stoned Dolphins: A Trip Through the World of Animal Intoxication, which just came out this year and is a lot of fun, as well as being full of interesting science! He also has a free children’s story called Arrow, the Lucky Planarian that you can download and read. It’s completely charming and you’ll learn a lot about planarians, which are also called flatworms, which are invertebrates, so this is all coming together! This week’s episode isn’t about planarians, though, but about lobsters. I don’t think we’ve ever discussed lobsters on the podcast before, oddly enough, but it’s been on my ideas list for a long time. When Pranav emailed me recently to suggest we do a lobster episode, I realized it was time! Time for lobsters! The lobster is a crustacean, and while there are plenty of different lobsters in the world, we’re going to focus on the clawed lobsters this time. There are lots of them, all grouped in the family Nephropidae. The lobster has eight legs that it walks on, and two more legs with pincers. That’s why it’s in the order Decapoda. Deca means ten and poda means feet. Ten feet. Some of which can pinch you if you’re not careful. The lobster uses its claws to defend itself from potential predators, and uses them to grab and kill small animals. It eats pretty much anything it can find, from fish and squid to sea stars and mollusks, to dead animals and some plant material. But its claws are too big and clumsy to use to eat with, which is why it has much smaller pincers on its next pairs of legs. These pincers are equipped with chemoreceptors that allow the lobster to taste its food before it actually eats it, which is a neat trick. The lobster uses these small claws to pull its food into smaller pieces and convey it to the mouthparts, which are under its head. Some mouthparts have sensory hairs that can taste food, some have sharp spines that act as teeth to tear food into smaller pieces, and others are small and just flutter to help keep pieces of food from floating away. The stomach is only about an inch away from the mouth, or about 2.5 cm, no matter the size of the lobster. The stomach itself, and the short esophagus leading to the stomach, are lined with chitin spines that act like teeth to grind food up while enzymes break it down to fully digest it. This seems like a really complicated way to eat, but it’s actually not all that different from the way we eat, it’s just that instead of mouthparts and stomach teeth, we do all our grinding up of food in the mouth with just one set of teeth.
