    Episode 472: The Hafgufa

    Further reading: Parallels for cetacean trap feeding and tread-water feeding in the historical record across two millennia Haggling over the Hafgufa Many renditions of the hafgufa/aspidochelone: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Back in the olden days, as much as 1700 years ago and probably more, up through the 14th century or so, various manuscripts about the natural world talked about a sea monster most people today have never heard of. In ancient Greek it was called aspidochelone, contracted to aspido in some translations, while in Old Norse it was called the hafgufa. But it seemed to be the same type of monster no matter who was writing about it. The animal was a fish, but it was enormous, big enough that it was sometimes mistaken for an island. When its jaws were open they were said to be as wide as the entrance to a fjord. A fjord is an inlet from the sea originally formed by glaciers scraping away at rocks, and then when the glaciers melted the sea filled the bottom of what was then a steep valley. I’m pretty sure the old stories were exaggerating about the sea monster’s mouth size. The sea monster ate little fish, but it caught them in a strange way. It would open its mouth very wide at the surface of the water and exude a smell that attracted fish, or in one account it would regurgitate a little food to attract the fish. Once there were lots of little fish within its huge mouth, it would close it jaws quickly and swallow them all. Generally, any sea monster that’s said to be mistaken for an island was inspired by whales, or sometimes by sea turtles. The hafgufa is actually included in an Old Norse poem that lists types of whales, and the aspidochelone was considered to be a type of whale even though the second part of its name refers to a sea turtle. So whatever this sea monster was, we can safely agree that it wasn’t a fish, it was a whale. Up until just a few centuries ago people thought whales were fish because of their shape, but we know now that they’re mammals adapted to marine life. But the hafgufa’s behavior is really weird and doesn’t seem like something a whale would do. We’ve talked about skim feeding before, where a baleen whale cruises along at the surface with its mouth held open, until it’s gathered enough food in its mouth and can swallow it all at once. But whales aren’t known to hold their mouths open at the surface of the water and just sit there while fish swim in. At least, they weren’t known to do this until 2011. In 2011, marine biologists studying humpback whales off Canada’s Vancouver Island in North America observed some of the whales catching herring and other small fish in an unusual way. The whales would remain stationary in the water, tails straight down with the head sticking up partly out of the water. A whale opened its mouth very wide and didn’t move until there were a lot of fish in its mouth, which it then swallowed. Soon after, another team of marine biologists studying Bryde’s whales in the Gulf of Thailand in South Asia observed the same activity when the whales were feeding on anchovies at the surface of the water. The term for this activity is called trap feeding or tread-water feeding, and at first the scientists thought it was a response to polluted water that had caused the fish to stay closer to the surface. But once the two teams of scientists compared notes, they realized that it didn’t appear to have anything to do with pollution. Instead, it’s probably a way to gather food in a low-energy way, especially when there isn’t a big concentration of fish in any particular spot, and when researchers remembered the story of the hafgufa, they realized they’d found the solution to that mystery sea monster. The only question was whether the accounts were accurate that the hafgufa emitted a smell or regurgitated food to attract fish. Further observation answered that question too, and it turns out that yes, the old stories were at least partially right. The smell has been compared to rotten cabbage, but it isn’t emitted by the whale on purpose. It’s a smell released when phytoplankton is eaten in large numbers, whether by fish or whales or something else, and it does attract other animals. As for the regurgitation, this is always something that happens to some degree when a baleen whale feeds. The whale fills its mouth with water that contains the fish and other small animals it eats, and it presses its huge tongue upwards to force the water through its baleen, which acts as a sieve. Whatever’s left in its mouth after the water is expelled, it swallows. But baleen is tough and fish are small and delicate in comparison. Often, fish and other small animals get squished to death against the baleen, and parts of them are expelled with the water. This creates a sort of yucky slurry that could be interpreted as a whale regurgitating food to attract more fish. The scientists ...

    Episode 471: Mystery Larvae
    Feb 9 2026
    Further reading: I Can Has Mutant Larvae? 200-Year-Old ‘Monster Larva’ Mystery Solved ‘Snakeworm’ mystery yields species new to science Hearkening back to the hazelworm Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. A few weeks ago when I was researching big eels, I remembered the mystery eel larva we talked about back in episode 49, and that led me down a fun rabbit hole about other mystery larvae. Let’s start with that eel larva. Eel larvae can be extremely hard to tell apart, so as a catchall term every eel larva is called a leptocephalus. They’re flattened side to side, which is properly referred to as laterally compressed, and transparent, shaped roughly like a slender leaf, with a tiny head at the front. Depending on the species, an eel may remain in its larval form for more than a year, much longer than most other fish, and when it does metamorphose into its next life stage, it usually grows much longer than its larval form. For instance, the larvae of conger eels are only about 4 inches long, or 10 cm, while an adult conger can grow up to 10 feet long, or 3 meters. On January 31, 1930, a Danish research ship caught an eel larva 900 feet deep, or about 275 meters, off the coast of South Africa. But the larva was over 6 feet long, or 1.85 meters! Scientists boggled at the thought that this larva might grow into an eel more than 50 feet long, or 15 meters, raising the possibility that this unknown eel might be the basis of many sea serpent sightings. The larva was preserved and has been studied extensively. In 1958, a similar eel larva was caught off of New Zealand. It and the 1930 specimen were determined to belong to the same species, which was named Leptocephalus giganteus. In 1966, two more of the larvae were discovered in the stomach of a western Atlantic lancet fish. They were much smaller than the others, though—only four inches and eleven inches long, or 10 cm and 28 cm respectively. Other than size, they were pretty much identical to Leptocephalus giganteus. The ichthyologist who examined them determined that the larvae were probably not true eels at all, but larvae of a fish called the spiny eel. Deep-sea spiny eels look superficially like eels but aren’t closely related, and while they do have a larval form that resembles that of a true eel, they’re much different in one important way. Spiny eel larvae grow larger than the adults, then shrink a little when they develop into their mature form. The six-foot eel larva was actually a spiny eel larva that was close to metamorphosing into its adult form. Not everyone agrees that Leptocephalus giganteus is a spiny eel. Some think it belongs to the genus Coloconger, also called worm eels, which are true eels but which have large larvae that only grow to the same size as adults. But worm eels don’t grow much bigger than about two feet long, or 61 cm. If the mystery larvae does belong to the genus Coloconger, it’s probably a new species. Until scientists identify an adult Leptocephalus giganteus, we can’t know for sure. Another mystery larva is Planctosphaera pelagica, which sits all alone in its own class because the only thing it resembles are acorn worms, but scientists are pretty sure it isn’t the larva of an acorn worm. It’s not much to look at, since the larva is just a little barrel-shaped blob that grows about 25 mm across. This sounds small compared to the eel larva we just discussed, but it’s actually quite large compared to similar larvae. Acorn worm larvae are usually only about a millimeter long. Planctosphaera has been classified as a hemichordate, which are related to echinoderms but which show bilateral symmetry instead of radial symmetry. Hemichordates are also closely related to chordates, which include all vertebrates. They’re marine animals that resemble worms but aren’t worms, so it’s likely that Planctosphaera is also wormlike as an adult. Planctosphaera isn’t encountered very often by scientists. It has limited swimming abilities and mostly floats around near the surface of the open ocean, eating tiny food particles. One suggestion is that it might actually be the larva of a known species, but one where an occasional larva just never metamorphoses into an adult. It just grows and grows until something eats it. So far, attempts to sequence DNA from a Planctosphaera hasn’t succeeded and attempts to raise one to maturity in captivity hasn’t worked either. Some people have estimated that an adult Planctosphaera might be a type of acorn worm that can grow nine feet long, or 2.75 meters, which isn’t out of the realm of possibility. The largest species of acorn worm known is Balanoglossus gigas, which can grow almost six feet long, or 1.8 meters, and not only is it bioluminescent, its body contains a lot of iodine, so it smells like medicine. It lives in mucus-lined burrows on the sea floor. Another mystery larva is Facetotecta, which have been found in ...

    Episode 470: Animals Discovered in 2025
    Feb 2 2026
    It’s the annual discoveries episode! Thanks to Stephen and Aryeh for their corrections and suggestions this week! Further reading: Salinella Salve: The Vanishing Creature That Defied Science for Over a Century Three new species of the genus Scutiger Baeticoniscus carmonaensis sp. nov. a new Isopod found in an underground aqueduct from the Roman period located in Southwest Spain (Crustacea, Isopoda, Trichoniscidae) A new species of supergiant Bathynomus Giant ‘Darth Vader’ sea bug discovered off the coast of Vietnam A New Species of easter egg weevil Bizarre ‘bone collector’ caterpillar discovered by UH scientists Researchers Discover ‘Death Ball’ Sponge and Dozens of Other Bizarre Deep-Sea Creatures in the Southern Ocean 1,500th Bat Species Discovered in Africa’s Equatorial Guinea Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to learn about some animals discovered in 2025! We’ll also make this our corrections episode. This is the last new episode we’ll have until the end of August when we reach our 500th episode, but don’t worry, until then there will be rescheduled Patreon episodes every single week as usual. We’ll start with some corrections. Shortly after episode 452 was published in September, where we talked about the swamp wallaby and some other animals, Stephen emailed to point out that I’d made a major mistake! In that episode I said that not all animals called wallabies were actually members of the family Macropodidae, but that’s actually not the case. All wallabies are macropodids, but they aren’t all members of the same genus in that family. I corrected the episode but I wanted to mention it here too so no one is confused. Stephen also caught another mistake in episode 458, which is embarrassing. I mentioned that marsupials didn’t just live in Australia, they were found all over the world. That’s not actually the case! Marsupials are found in North and South America, Australia, New Guinea and nearby areas, and that’s it. They were once also found in what is now Asia, but that was millions of years ago. So I apologize to everyone in Africa, Asia, and Europe who were excited about finding out what their local marsupials are. You don’t have any, sorry. One update that Aryeh asked about specifically is an animal we talked about in episode 445, salinella. Aryeh emailed asking for more information if I could find any, because it’s such a fascinating mystery! I looked for some more recent findings, unfortunately without luck. I do have an article linked in the show notes that goes into detail about everything we covered in that episode, though, dated to mid-January 2026, and it’s a nice clear account. Now, let’s get into the 2025 discoveries! There are lots more animals that were discovered last year, but I just chose some that I thought were especially interesting. Mostly I chose ones that I thought had funny names. Let’s start with three new species of frog in the genus Scutiger. Species in this genus are called lazy toads and I couldn’t find out why. Maybe they don’t like to move around too much. Lazy toads live in mountains in some parts of Asia, and we don’t know very much about most of the 31 species described so far. Probably the most common lazy toad is the Sikkim lazy toad that lives along high altitude streams in the Himalaya Mountains. It’s mottled greenish-brown and yellowish in color with lots of warts, and while its feet have webbed toes, it doesn’t have webbed fingers on its little froggy hands. This is your reminder that every toad is a frog but not every frog is a toad. The Sikkim lazy toad grows about two and a half inches long, or about 65 mm, from nose to butt. It seems to be pretty average for a lazy toad. The three new species of lazy toad are found in Yunnan Province in China, in a mountainous region where several species of lazy toad were already known. Between 2021 and 2024, a team of scientists collected 27 lazy toads from various places, then carefully examined them to see if they were species already known to science. This included genetic analysis. The team compared their findings with other lazy toad species and discovered that not all of the specimens matched any known species. Further comparison with each other revealed that the team had discovered three new species, which they described in December of 2025. Next, isopods are common crustaceans that live throughout the world. You have undoubtedly seen at least one species of isopod, because an animal with lots of common names, including woodlouse, pill bug, roly-poly, and sowbug, is a terrestrial isopod. That’s right, the roly-poly is not a bug or a centipede but a crustacean. The order Isopoda contains more than 10,000 species, and there are undoubtedly thousands more that haven’t been discovered by scientists yet. About half the species discovered so far live on land and the other half live in ...

I’m your host, Kate Shaw. This week we’re going to talk about some amphibians and fish. Thanks to Aila, Stella, George, Richard from NC, Emilia, Emerson, and Audie for their suggestions! We’ll start with Audie’s suggestion, the sandbar shark. It’s an endangered shark that lives in shallow coastal water in the Atlantic and Indo-Pacific Oceans. A big female can grow over 8 feet long, or 2.5 meters, while males are smaller on average. It can be brown or gray in color, and its dorsal fin is especially big for a shark its size. The sandbar shark eats fish, crustaceans like crabs, cephalopods like octopuses, and other small animals. It spends a lot of time near the bottom of the seabed, looking for food, and it will also swim into the mouths of rivers. Since it resembles a bull shark, which can live just fine in rivers for quite a while and which can be dangerous to swimmers, people are sometimes afraid of the sandbar shark, but it hardly ever bites people. It just wants to be left alone to find little fish to eat. Emilia and Emerson both asked to learn more about eels. Eels are fish, but not every animal that’s called an eel is actually an eel. Some are just eel-shaped, meaning they’re long and slender. Electric eels aren’t actually eels, for instance, but are more closely related to catfish. The longest eel ever reliably measured was a slender giant moray. That was in 1927 in Queensland, Australia. The eel measured just shy of 13 feet long, or 3.94 meters. We talked about some giant eels in episode 401, but this week let’s talk about a much smaller eel, one that Emerson suggested. That’s the snipe eel, the name for a family of eels consisting of nine species known so far. They live in every ocean in the world, and some species are deep-sea animals but most live a little nearer the surface. The largest species can grow an estimated 5 feet long, or 1.5 meters, but because all species of snipe eel are so incredibly thin, even the longest individual weighs less than a football, either American or regular, take your pick. The snipe eel gets its name from its mouth, which is long and slightly resembles the beak of a bird called the snipe. The snipe is a wading bird that pokes its long, flexible bill into mud to find small animals like insect larvae, worms, and snails. But unlike the bird’s bill, the snipe eel’s jaws have a bend at the tip. The upper jaw bends upward, the lower jaw bends downward so that the tip of the jaws are separated. It doesn’t look like that would be very helpful for catching food, but scientists think it helps because the fish’s mouth is basically always open. Since it mainly eats tiny crustaceans floating in the water, it doesn’t even need to open its mouth to catch food. It has tiny teeth along the jaws that point backwards, so when a crustacean gets caught on the teeth, it can’t escape. The slender snipe eel is especially unusual because it can have as many as 750 vertebrae in its backbone. That’s more than any other animal known. Most of its length is basically just an incredibly long, thin tail, with its organs bunched up right behind its head. Even its anus is basically on its throat. We don’t know a whole lot about the snipe eel, since it lives deep enough that it’s hardly ever seen by humans. Most of the specimens discovered have been found in the stomachs of larger fish. Now, let’s leave the world of fish behind and look at some amphibians. First, George wanted to learn about the hellbender, and points out that it’s also called the snot otter or lasagna lizard. I don’t understand the lasagna part but it’s funny. The hellbender is a giant salamander that lives in parts of the eastern United States, especially in the Appalachian Mountains and the Ozarks. It can grow nearly 30 inches long, or 74 cm, and is the fifth heaviest amphibian alive today in the whole world. It spends almost all its life in shallow, fast-moving streams hiding among rocks. As water rushes over and around rocks, it absorbs more oxygen, which is good for the hellbender because as an adult it breathes through its skin. To increase its surface area and help it absorb that much more...

I’m your host, Kate Shaw. This week we’re going to look at some mammals suggested by Conner, Tim, Stella, Cillian, Eilee, PJ, and Morris. Let’s jump right in, because we have a lot of fascinating animals to learn about! We’ll start with suggestions by Cillian and Eilee, who both suggested a monkey called the tamarin. Tamarins live in Central and South America and there are around 20 species, all of them quite small. Cillian specifically suggested the golden lion tamarin, an endangered species that lives in a single small part of Brazil. It has beautiful golden or orange fur that’s longer around the face, like a lion’s mane but extremely stylish. Its face is bare of fur and is gray or grayish-pink in color, with dark eyes and a serious expression like it’s not sure where it left its wallet. It grows about 10 inches long, or 26 cm, not counting its extremely long tail. The golden lion tamarin spends most of its time in trees, where it eats fruit, flowers, and other plant material, along with eggs, tree frogs, insects, and other small animals. It has narrow hands and long fingers to help it reach into little tree hollows and crevices where insects are hiding, but if it can’t reach an insect that way, it will use a twig or other tool to help. The golden lion tamarin lives in small family groups, usually a mated pair and their young children. A mother golden lion tamarin often has twins, sometimes triplets, and the other members of her family help take care of the babies. Because the golden lion tamarin is endangered, mainly due to habitat loss, zoos throughout the world have helped increase the number of babies born in captivity. When it’s safe to release them into the wild, instead of only releasing the young tamarins, the entire family group is released together. Eilee suggested the cotton-top tamarin, which lives in one small part of Colombia. It’s about the same size as the golden lion tamarin, but is more lightly built and has a somewhat shorter tail. It’s mostly various shades of brown and tan with a dark gray face, but it also has long white hair on its head. Its hair sticks up and makes it look a little bit like those pictures of Einstein, if Einstein was a tiny little monkey. Like the golden lion tamarin, the cotton-top tamarin lives in small groups and eats both plant material and insects. It’s also critically endangered due to habitat loss, and it’s strictly protected these days. Next, both Tim and Stella suggested we learn about the pangolin. There are eight species known, which live in parts of Africa and Asia. The pangolin is a mammal, but it’s covered in scales except for its belly and face. The scales are made of keratin, the same protein that makes up fingernails, hair, hooves, and other hard parts in mammals. When it’s threatened, it rolls up into a ball with its tail over its face, and the sharp-edged, overlapping scales protect it from being bitten or clawed. It has a long, thick tail, short, strong legs with claws, a small head, and very small ears. Its muzzle is long with a nose pad at the end, it has a long sticky tongue, and it has no teeth. It’s nocturnal and uses its big front claws to dig into termite mounds and ant colonies. It has poor vision but a good sense of smell. Some species of pangolin live in trees and spend the daytime sleeping in a hollow tree. Other species live on the ground and dig deep burrows to sleep in during the day. It’s a solitary animal and just about the only time adult pangolins spend time together is when a pair comes together to mate. Sometimes two males fight over a female, and they do so by slapping each other with their big tails. Unfortunately for the pangolin, its scales make it sought after by humans for decoration. People also eat pangolins. Habitat loss is also making it tough for the pangolin. All species of pangolin in Asia are endangered or critically endangered, while all species of pangolins in Africa are vulnerable. Pangolins also don’t do well in captivity so it’s hard for zoos to help them. Next, Conner wants to learn about the lemming, a rodent that’s related to muskrats and voles. Lots of people think they know one thing about the lemming, but that thing isn’t true. We’ll talk ...

I’m your host, Kate Shaw. This week we have an episode about some birds and reptiles. Thanks to Audie, Katie, Eilee, Emily, Maryjane, and Dylan for their suggestions! If this episode showed up later than usual in the podcast feed, it’s because I’ve been having trouble with the website and couldn’t get it uploaded until it was fixed. We’ll kick off the episode with an animal that can’t kick, because snakes don’t have any legs. Audie suggested we learn about the scaleless rat snake, which means that first we have to learn about the rat snake, the ordinary one with scales. Rat snakes are constrictors and are common throughout many parts of Asia, Europe, North America, and the Middle East, and they’re called rat snakes because they eat rats and other small animals like lizards, frogs, and baby birds. Rat snakes are popular pets because they’re so pretty and they aren’t dangerous to humans. Different species are different colors and patterns, and the rhinoceros rat snake, also called the Vietnamese longnose snake, even has a little hornlike projection on the tip of its nose that points forward. I’m pretty sure we’ve talked about that particular rat snake before on the podcast, but I can’t look up which episode because the website is down. Most rat snakes don’t grow much bigger than 5 feet long, or 1.5 meters, but a few species can get longer than that. The black rat snake, which lives in North America, can grow over 8 feet long, or more than 2.5 meters. It’s black with small white markings on the head, but snakes bred for sale as pets are sometimes white all over or partially white, or even albino, meaning an individual has a mutation where its body doesn’t produce pigment. Pet black rat snakes are also bred that don’t have scales. That brings us to the scaleless rat snake. It’s an ordinary rat snake but it has a mutation that causes it to have very few scales. This is a mutation that happens occasionally in the wild since it’s a recessive trait, and while it can make the snake a little more vulnerable to injury, scaleless snakes can survive just fine in the wild. They do have belly scales like a normal snake, which are the ones that allow them to move around, and they may have a scattering of scales on other parts of the body too. A scaleless snake still sheds its skin once a year like an ordinary snake, since it’s actually the outer layer of skin that sheds along with the scales. Scaleless rat snakes are popular as pets because they’re so soft and because their coloration is usually very bright. A snake’s coloration comes from pigments in its skin. A snake’s scales are actually transparent, so without a layer of scales, a scaleless snake looks even more colorful than a regular snake. Many species of snake have been found in the wild that are scaleless, but it seems to be a little more common in rat snakes. Next, Dylan and Emily wanted to learn about the frill-neck lizard, which is found in northern Australia and the very southern part of New Guinea. It’s a big lizard that can grow almost three feet long, or 90 cm, including its incredibly long tail. Males are larger than females on average, with a bigger frill. The frill is a flap of skin around the head and neck, and most of the time it’s folded back over the neck and shoulders so it’s not that noticeable. The lizard is pretty ordinary-looking that way, just a big gray or brown animal with a big head. But when the lizard feels threatened, or if it comes across another frill-neck lizard, it can extend the frill by moving the small bones and cartilage that act as struts, which also requires the lizard to open its mouth. When extended, the frill is as much as a foot across, or 30 cm, and it’s marked with bright colors. Different individuals have different colored frills, red, orange, yellow, or white, or a mixture of colors and patterns. The size and color of the frill opening up so quickly will often startle a potential predator, allowing the lizard to escape. The frill-neck lizard can even run on two legs if it needs to, although it has to run with its head pointing straight up in the air. The frill-neck lizard mostly eats insects, especially termites. It spends most of its time in trees and some people believe it can use its frill as a parachute, but that doesn’t actually seem to be the case. Let’s move on to a few birds next.

Hello to 2026! This is usually where I announce that I’m going to do a series of themed episodes throughout the coming year, and usually I forget all about it after a few months. This year I have a different announcement. After our nine-year anniversary next month, which is episode 470, instead of new episodes I’m going to be switching to old Patreon episodes. I closed the Patreon permanently at the end of December but all the best episodes will now run in the main feed until our ten-year anniversary in February 2027. That’s episode 523, when we’ll have a big new episode that will also be the very last one ever. I thought this was the best way to close out the podcast instead of just stopping one day. The only problem is the big list of suggestions. During January I’m going to cover as many suggestions as I possibly can. This week’s episode is about invertebrates, and in the next few weeks we’ll have an episode about mammals, one about reptiles and birds, and one about amphibians and fish, although I don’t know what order they’ll be in yet. Episode 470 will be about animals discovered in 2025, along with some corrections and updates. I hope no one is sad about the podcast ending! You have a whole year to get used to it, and the old episodes will remain forever on the website so you can listen whenever you like. All that out of the way, let’s start 2026 right with a whole lot of invertebrates! Thanks to Sam, warbrlwatchr, Jayson, Richard from NC, Holly, Kabir, Stewie, Thaddeus, and Trech for their suggestions this week! Let’s start with Trech’s suggestion, a humble ant called the weaver ant. It’s also called the green ant even though not all species are green, because a species found in Australia is partially green. Most species are red, brown, or yellowish, and they’re found in parts of northern and western Australia, southern Asia, and on most islands in between the two areas, and in parts of central Africa. The weaver ant lives in trees in tropical areas, and gets the name weaver ant because of the way it makes its nest. The nests are made out of leaves, but the leaves are still growing on the tree. Worker ants grab the edge of a leaf in their mandibles, then pull the leaf toward another leaf or sometimes double the leaf over. Sometimes ants have to make a chain to reach another leaf, with each ant grabbing the next ant around the middle until the ant at the end of the chain can grab the edge of a leaf. While the leaf is being pulled into place alongside the edge of another leaf, or the opposite edge of the same leaf, other workers bring larvae from an established part of the nest. The larvae secrete silk to make cocoons, but a worker ant holds a larva at the edge of the leaf, taps its little head, and the larva secretes silk that the workers use to bind the leaf edges together. A single colony has multiple nests, often in more than one tree, and are constantly constructing new ones as the old leaves are damaged by weather or just die off naturally. The weaver ant mainly eats insects, which is good for the trees because many of the insects the ants kill and eat are ones that can damage trees. This is one reason why farmers in some places like seeing weaver ants, especially fruit farmers, and sometimes farmers will even buy a weaver ant colony starter pack to place in their trees deliberately. The farmer doesn’t have to use pesticides, and the weaver ants even cause some fruit- and leaf-eating animals to stay away, because the ants can give a painful bite. People in many areas also eat the weaver ant larvae, which is considered a delicacy. Our next suggestion is by Holly, the zombie snail. I actually covered this in a Patreon episode, but I didn’t schedule it for next year because I thought I’d used the information already in a regular episode, but now I can’t find it. So let’s talk about it now! In August of 2019, hikers in Taiwan came across a snail that looked like it was on its way to a rave. It had what looked like flashing neon decorations in its head, pulsing in green and orange. Strobing colors are just not something you’d expect to find on an animal, or if you did it would be a deep-sea animal. The situation is not good for the snail, let me ...

    Episode 465: The Mermaid
    Dec 29 2025
    Thanks to Holly for suggesting this week’s topic! Further reading: Mermaids: Myth, Kith and Kin [this article is not for children] Feejee Mermaid A manatee: A female grey seal, looking winsome: A drawing of the “original” Fiji (or Feejee) mermaid: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Let’s close out the year 2025 with a mystery episode! Holly suggested we talk about mermaids! Mermaids are creatures of folklore who are supposed to look like humans, but instead of legs they have fish tails. These days mermaids are usually depicted with a single tail, but it was common in older artwork for a mermaid to be shown with two tails, which replaced both legs. Not all mermaids were girls, either. Mermen were just as common. Cultures from around the world have stories about mermaid-like individuals. Sometimes they’re gods or goddesses, like the Syrian story of a goddess so beautiful that when she transformed into a fish, only her legs changed, because her upper half was too beautiful to alter, or the Greek god Triton, who is usually depicted as a man with two fish tails for legs. Sometimes they’re monsters who cause storms, curse ships, or lure sailors to their doom. Sometimes they can transform into humans, like the story from Madagascar about a fisherman who catches a mermaid in his net. She transforms into a human woman and they get married, but when he breaks a promise to her, she turns back into a mermaid and swims away. In 2012, a TV special aired on Animal Planet that claimed that mermaids were real, and a lot of people believed it. It imitated the kind of real documentaries that Animal Planet often ran, and the only disclaimer was in the credits. I remember how upset a lot of people were about it, especially teachers and scientists. So just to be clear, mermaids aren’t real. Many researchers think at least some mermaid stories might be based on real animals. The explorer Christopher Columbus reported seeing three mermaids in 1493, but said they weren’t as beautiful as he’d heard. Most researchers think he actually saw manatees. A few centuries later, a mermaid was captured and killed off the coast of Brazil by European scientists, and the careful drawings we still have of the mermaid’s hand bones correspond exactly to the bones of a manatee’s flipper. Female manatees are larger than males on average, and a really big female can grow over 15 feet long, or 4.6 meters. Most manatees are between 9 and 10 feet long, or a little less than 3 meters. Its body is elongated like a whale’s, but unlike a whale it’s slow, usually only swimming about as fast as a human can swim. Its skin is gray or brown although often it has algae growing on it that helps camouflage it. The end of the manatee’s tail looks like a rounded paddle, and it has front flippers but no rear limbs. Its face is rounded with a prehensile upper lip covered with bristly whiskers, which it uses to find and gather water plants. The manatee doesn’t look a lot like a person, but it looks more like a person than most water animals. It has a neck and can turn its head like a person, its flippers are fairly long and resemble arms, and females have a pair of teats that are near their armpits, if a manatee had armpits, which it does not. But that’s close enough for Christopher Columbus to decide he was seeing a mermaid. Seals may have also contributed to mermaid stories. In Scottish folklore, the selkie is a seal that can transform into human shape, usually by taking off its skin. There are lots of stories of people who steal the selkie’s skin and hide it so that the selkie will marry the person—because selkies are beautiful in their human form. Eventually the selkie finds the hidden skin and returns to the sea. Similar seal-folk legends are found in other parts of northern Europe, including Sweden, Iceland, Norway, and Ireland. Many of the stories overlap with mermaid stories. Seals do have appealing human-like faces, have clawed front flippers that sort of resemble arms, and have rear flippers that are fused to act like a tail, even if it doesn’t look much like a fish tail. The grey seal is a common animal off the coast of northern Europe, and a big male can grow almost 11 feet long, or 3.3 meters, although 9 feet is more common, or 2.7 meters. It has a large snout and no external ear flaps. Males are dark grey or brown, females are more silvery in color. It mainly eats fish, but will also eat other animals, including crustaceans, octopuses, other seals, and even porpoises. While I don’t think it has anything to do with the mermaid or selkie legends, it is interesting to note that seals are good at imitating human voices. We learned about this in episode 225, about talking mammals. For instance, Hoover the talking seal, a harbor seal from Maine who was raised by a human after his mother died. Imagine if you were walking along the shore and a seal said this to you: [...
