Episode 505: Three Animal Mysteries
Further reading: Scientists solve a shark murder mystery Stone Age Animal Urine Could Solve a Mystery about Technological Development South African rock art possibly inspired by long-extinct species The porbeagle shark [photo by Andy Murch, taken from this site]: Dicynodont fossils and their possible art interpretation by the San people: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. It’s finally monster month, and I’m looking forward to sharing lots of fun mystery animals and animal mysteries over the next four weeks. Our first mystery is from an article titled “Scientists solve a shark murder mystery.” The word solve is doing a lot of heavy lifting in this case, but let’s find out what happened to the shark. The shark in question was a porbeagle shark, a type of mackerel shark that can grow as much as 12 feet long, or over 3.5 meters, and is gray and white in color. It lives in cold water in the North Atlantic and around Antarctica, and it eats fish and cephalopods like squid. It hardly ever bothers people although people like to eat it, and in some regions it’s been so overfished that the species is listed as endangered. The porbeagle is especially unusual because it’s able to thermoregulate to some degree, like the basking shark and some other sharks that we talked about in episode 353, about warm-blooded fish. The porbeagle is actually really good at keeping its brain, eyes, and internal organs warm, which is why it’s so successful in cold water. It can live to be at least 65 years old. There’s still a lot we don’t know about the porbeagle, including where exactly it lives and how far it migrates throughout the year. A team of scientists has been tagging porbeagle sharks with little transmitters, like shark Air Tags, to find out where the sharks travel and other information, like how deeply they dive and what the water temperature is. The transmitter is attached to a shark’s fin and is designed to stay in place for a year, then detach and transmit all the information it’s gathered as soon as it floats to the water’s surface. In October 2020, the scientists captured an 8-foot, or 2.5 meter, female porbeagle and fitted her with a transmitter before releasing her again. They were especially happy to see that she was pregnant, partly because the porbeagle is endangered and reproduces slowly, partly because they were interested to find out where a pregnant shark traveled. About six months later, in April 2021, the tag began to transmit its information. It was too early for it to have detached on its own, but sometimes something happens to a tag and it ends up removed from the shark before it’s scheduled to. The team’s lead scientist, Brooke Anderson, examined the transmitter’s information and knew something weird had happened to the shark. Everything seemed normal until about a week before the tag began to transmit, when the tag indicated a slight but steady increase in the temperature of its surroundings, even though it was still deep underwater. Anderson suspected that the shark had been killed and eaten at that point, and the tag ended up inside the body of another ani

Episode 504: The Mystery Roar
Further reading: Wolves on rise in France as bears wreak mountain havoc Can Brown Bears Survive in the Pyrenees? Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. On the evening of August 4, 2019, two hikers set up camp in the Pyrenees Mountains. Laurent and Frédéric were familiar with the area and had plenty of experience hiking and camping. Once their camp was ready for the night, they took off their boots and socks and sat down to eat dinner and relax at a small campfire. If you’ve ever camped after a long hike, you’ll know that this is the best time of the day, when you can rest and air out your boots. After only a few minutes, though, the two heard grunts and growls in the darkness not far from their camp. They were concerned, but they had a fire and most animals won’t approach a fire. But the sounds got closer and closer. Then the animal roared—and it sounded like it was much closer than before. Laurent and Frédéric remembered that bears have become more common in the Pyrenees in the last few decades, and rather than take their chances with a hungry bear, they decided it was time to go. They shoved their bare feet into their boots, left everything behind, and raced back down the trail. It was late when they made it to the village of Germ so the hikers took refuge in a church where they spent the night. In the morning they hiked back up to their campsite to retrieve their belongings, expecting it to be trashed by a bear hunting for food. But everything was where they’d left it. Some people assumed the hikers had panicked over nothing, but the men were adamant that they’d heard something roaring as it came closer. In a news interview they said the final roar, the one that made them grab their boots and run, lasted several seconds and was so loud they could actually feel it in their chests. Brown bears were once fairly common in the Pyrenees but by 1991 they had all been killed, mostly by hunters. Habitat loss was also a factor as people built more roads and houses in the mountains. In 1995 a conservation program brought three bears from Slovenia to start a reintroduction program, and the way people acted, you’d think someone had released a thousand rabid weasels into their homes. Sheep and cattle farmers, and people who think the wilderness belongs to humans and humans only, protested the reintroduction of the bears, and one of the bears was shot and killed. This is despite the fact that farmers whose livestock are killed by bears get paid a lot of money by the French government. Approximately 1,000 sheep a year are killed in the Pyrenees—not by bears, but by pet dogs running loose. Conservation efforts continued despite protests and finally, by 2020, there were 64 bears living in the Pyrenees Mountains. The number may be a little larger—some estimates are as high as 100—but conservationists have difficulty counting the bears properly because protesters threaten them and in one case actually set a conservationist’s car on fire. The Pyrenees mountain range more or less divides France from Spain. It’s older than the Alps and especially known for its spectacular waterfalls. Many plants and animals that live in the Pyrenees are found nowhere else in the world, but unfortunately hunting and habitat loss have driven many of them to extinction. The Pyrenean ibex, a type of wild goat, went extinct in the year 2000. Conservationists have introduced a related animal, the western Spanish ibex, to help keep the mountain ecosystems healthy. The bears now living in the mountains are similarly important to the ecosystems. Conservationists are frustrated by protesters who don’t want bears in the mountains at all, especially considering that the Great Pyrenees dog was developed in the area to protect livestock from bears and other predators. Some shepherds in British Columbia, Canada, where both black bears and grizzlies live, successfully use Great Pyrenees dogs to guard their flocks from bears. Grizzlies are a subspecies of brown bear. But let’s go back to Laurent and Frédéric’s scary camping trip. Did they really encounter a bear or could it be something else? Bears are generally quite shy animals who avoid people when they can. Unlike black bears, which don’t growl, brown bears do make growling and grunting sounds occasionally. Males will growl or even roar at other males during mating season in spring and early summer, signaling aggression and the willingness to fight. A brown bear will sometimes growl or roar at a person to warn them away too. So it’s possible the hikers heard a bear who wasn’t interested in their food but just

Episode 503: The Mystery of Typhloesus
Further reading: A possible home for a bizarre Carboniferous animal: is Typhloesus a pelagic gastropod? Typhloesus An artist’s rendition of what Typhloesus might have looked like [pic taken from the Nix Illustration link above]: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. I recently discovered the excellent Nix Illustration blog, which is about scientific illustration and palaeontology. I’m finding so many fun topics that I keep going back to it, so I hope you don’t mind another invertebrate mystery I learned about from the site. There are links in the show notes if you want to read the original blog posts. This month’s mystery is Typhloesus wellsi, sometimes referred to as the “alien goldfish” because of its shape and its peculiar anatomy. It definitely wasn’t a fish. It lived around 324 million years ago and was first discovered in the early 1970s in Montana, in the middle of North America. It grew up to four inches long, or 10 cm, and was shaped not like a real goldfish but kind of like a goldfish cracker. Its body was roughly cylinder-shaped, and it had a vertical tail fin and a pair of fin-like lobes on its sides that are referred to as keels. But it didn’t have eyes or, as far as scientists can determine, an anus. It did have a mouth and gut cavity–but it also had something truly unexpected and mysterious in its body, a pair of disc-shaped organs that contained a lot of iron but whose function is completely unknown and unlike anything scientists have ever seen. Those initial specimens also contained lots of conodont teeth, which led scientists to hope they’d finally discovered the conodont animal. We’ve talked about conodont teeth before, but it’s been quite a while ago. Conodont animals were incredibly common for around 300 million years, and their teeth are found throughout the world. Technically they’re not teeth but tooth-like structures called conodont elements, some of them microscopic, some of them almost an inch long, or 2 cm. Each animal had three types of conodont elements, and they interacted in a way that we don’t fully understand since they were completely different from modern animal mouthparts. Until the 1980s, no one knew what the conodont animal looked like. The only fossils we had were the tiny teeth. Then some body impressions of the conodont animal were discovered. Now we know it was shaped like an eel and grew up to 20 inches long, or 50 cm. We also know it had large eyes, a notochord (or primitive spine), and fins on the tail end. It was probably related to hagfish and lampreys and may have looked similar, although not everyone agrees with this classification. Whatever the conodont animal was related to, Typhloesus definitely wasn’t one. It turns out that the conodont teeth associated with Typhloesus fossils were actually in its gut, after the alien goldfish ate a conodont animal. So scientists were back to square one. What was Typhloesus? In 2022, a study of several specimens revealed a clue. Typhloesus had a radula. That’s a mouthpart that resembles a tooth-studded tongue. Snails, for instance, use tiny radulas to scrape algae and other food off of rocks. True radulas are a trait of mollusks, which means Typhloesus was most likely an early mollusk, maybe even a gastropod like snails and slugs. That’s a start to classifying Typhloesus, but it doesn’t explain the pair of weird disc-shaped organs. It’s called a ferrodiscus and we still don’t know what it was for. Because of its placement just under the midgut and its high concentration of iron, which would have made it quite hard in comparison to most of the rest of its body, the ferrodiscus might have had something to do with digestion. Then again, it might have had something to do with chemoreception, which is probably how Typhloesus found its food. Some modern mollusks have a chemoreceptor organ under the radula, but it’s mainly a bundle of nerve cells and not any kind of weird iron discs. We just don’t know what the ferrodiscus was.

Episode 502: Back to the Ocean
Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Life arose in the oceans and only much later spread to the land. But some land animals returned to the ocean and eventually became fully marine animals. That’s our topic this month, animals that returned to the sea. Vertebrates that evolved on land are called tetrapods, meaning four-footed. It applies even to animals like birds that have two legs and two wings, and snakes that have no legs, because all the ancestors of tetrapods had four legs. Returning to marine life as a tetrapod eventually results in an animal developing certain characteristics. Even animals like sea turtles become more streamlined, which helps the animal swim more easily, and arms and legs develop into flippers for the same reason. Sometimes limbs are lost completely, like the rear legs of cetaceans and sirenians, because they’re not needed. One interesting note is that as far as we know, all marine tetrapods still have to breathe air, which requires them to come to the surface of the water periodically. The ancestors of marine tetrapods probably all started out as partially aquatic and gradually became more and more at home in the water. That’s true even for animals as well adapted to marine life as whales. Some of the earliest whale ancestors were the ambulocetids, which probably looked sort of like a cross between a hippopotamus and a crocodile. Ambulocetid means “walking whale,” but there’s some evidence that it might have already evolved to be fully aquatic 49 million years ago. It had short legs that might not have been strong enough to support it out of water. It might have been covered with short fur like a seal but it might have had little to no fur, more like a hippopotamus. Either way, it had long toothy jaws, strong legs with webbed toes that it used to propel itself through the water, and a tail that probably resembled that of an otter. It grew about ten feet long, or 3 meters. Ambulocetids lived in shallow coastal areas where the land was swampy, and it may have spent part of its time in fresh water. It wouldn’t have looked or acted much like a whale to us, but it was already developing features now found only in whales. By around 41 million years ago, the basilosaurids and their close relations had evolved, and were definitely fully aquatic. Their nostrils had moved almost to the location of modern whales’ blowholes. Their forelegs were basically flippers with little fingers, their hind legs had almost disappeared, and they had tail flukes. They were also much bigger than their ancestors. Basilosaurus could grow up to 60 feet long, or 18 meters, and probably looked more like a gigantic eel than a modern whale. It was long and relatively thin, and may have mostly lived at the ocean’s surface instead of diving for food. Dakosaurus wasn’t a dinosaur despite its name, although it lived at the same time as the dinosaurs, about 145 million years ago. It was a crocodylomorph that grew up to about 16 feet long, or 5 meters, and looked kind of like a shark with legs—but also a lot like a crocodile wearing a shark costume. Its tail had a fin near the end that made it resemble a shark’s tail, and its legs were flipper-like but still obviously legs. It had a whole lot of big serrated teeth in a deep skull with strong jaws. Because its jaws and teeth were so strong, in fact, scientists think Dakosaurus probably ate other marine reptiles instead of just fish. While Dakosaurus was streamlined and well adapted to life in the ocean, we don’t know if it left the water to lay its eggs on land the way sea turtles still do or if it gave birth in the water. We don’t have any nest sites or young specimens one way or another. Other marine reptiles definitely gave birth in the water, including ichthyosaurs. Ichthyosaurs and their close relations were incredibly successful, first appearing in the fossil record around 250 million years ago and last appearing around 90 million years ago. Most ichthyosaurs grew around 6 and a half to 11 feet long, or 2 to 3.3 meters, depending on species, so while they were pretty big animals, they weren’t enormous. They would have been fast, though, and looked a lot like fish or dolphins, with four flippers, a dorsal fin, a long tail with fins, and a long thin rostrum with lots of little teeth. We know they gave birth to live young because we have fossils of female ichthyosaurs who died in the process of giving birth, with the baby’s tail outside of its mother but the rest of it still in the birth canal. We have other fossils of ichthyosaurs with partially developed young in what would have been the mother’s uterus. We also have lots of ichthyosaur coprolites that show us what it ate, since the coprolites fossilized with pieces of undigested food in them. This includes fish scales and squid beaks. Of course, if you want to talk a

Episode 501: The Wee Waa Monster and Tupandactylus
Further reading: Pterosaur melanosomes support signalling functions for early feathers Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This month we have a small mystery from Australia, which as far as I can find is still unsolved. In 1950, a man named George Gray started hearing bellowing from the gum swamp near his house. His adult son, Ted, heard it too and reported it was loud enough to hear half a mile away, or about 800 meters. The bellowing sounded like a crocodile. The problem is, the Grays lived just outside of the small town of Wee Waa in New South Wales, Australia. Very, very rarely a saltwater crocodile wanders down the coast as far as New South Wales, but Wee Waa is a five or six hour drive inland. It’s not crocodile country. It gets cold in winter and it’s surrounded by farmland. Ted Gray found tracks in the swamp where a large animal had flattened tall grass, although the footprints didn’t have claw marks. He estimated that if the animal was a crocodile, it was only about 6 feet long, or 1.8 meters, although he did note that none of the trails seemed to lead to the water. The bellowing mostly occurred in early morning and around sundown and continued for several months. Attempts to search the wetlands were unsuccessful, mostly because of heavy rain that spring and summer. The water was ordinarily no more than 3 feet deep, or about a meter [actually about 92 cm, got this wrong], but was much deeper that year. Hundreds of people came to listen to the bellowing, though, and one constable perched in a tree for most of a day hoping to shoot the animal. He never saw it. Seven years earlier, during World War II, an armored division of troops stayed in the area. The troops had been based in northwest Australia for a time and were supposed to have brought some baby crocodiles with them as mascots. The soldiers were told to kill the crocodiles, but newspapers in 1950 suggested they’d been released instead and that one had found its way to George Gray’s swamp. That doesn’t explain how it survived seven winters or why no one had seen or heard it until then. Then again, one man named Ross Tuckey claimed he’d seen a crocodile several years before about 20 miles away, or 32 kilometers. He’d first thought it was a goanna, which is a type of monitor lizard that lives in Australia. Some species of goanna can grow more than 8 feet long, or about 2.5 meters. When Tuckey’s dog rushed at the animal, it bowled the dog away with its tail and slid into a dammed stream. Tuckey watched it float in the water with only its nostrils visible. The Wee Waa monster was never identified. That’s all there is! I tried to find out more but if anyone ever found what animal was bellowing in George Gray’s swamp, the newspapers didn’t report about it. I actually only learned about this animal mystery when I was searching for something else, which is always a lot of fun. *** 115 million years ago a colony of strange flying animals lived in what is now northeastern Brazil in South America. It was a reptile that lived at the same time as dinosaurs, but it wasn’t a dinosaur. It wasn’t a bird either. Its wingspan might have been as much as 13 feet across, or 4 meters, which was big for a pterosaur, which of course is what it was. Specifically, it’s Tupandactylus imperator [too-pan-DAK-tillus imper-AH-ter], and it is a complete weirdo. Tupandactylus was only described in 1997, but we have several really well preserved specimens, including nearly complete skulls. And it’s the skull that makes it so bizarre. Many pterosaurs had large crests that were probably brightly colored and probably used to attract mates, but Tupandactylus had what may be the largest crest ever found. It was just ridiculously large, nearly as big as its whole body, not counting its wings, of course. Tupandactylus’s skull is hard to describe. I’m going to do my best, but you might want to click through to the show notes and look at the picture. First, imagine a pelican’s bill. It’s long and has a pouch underneath. But in your mental picture, push that pouch forward so that it’s at the base of the lower jaw like a chin, and made of bone instead of soft tissue. Tupandactylus had a sort of

NEW Episode 500: Crikey, it’s 500 episodes!
It’s our 500th episode! Wow! Thanks to Rosie, Remy and Julien, and Dylan, Emily, and Michelle for their suggestions this week! Further reading: Crikey! Newly Discovered Snake Species Named After Steve Irwin Steve Irwin’s Treesnail A young Steve Irwin’s tree snail [photo taken from link above]: A marbled lungfish: A fennec, smallest and cutest of all foxes: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we have a brand new episode, because it’s episode 500! Congratulations to me and to you too, listening to the 500th episode of a podcast! That doesn’t happen very often! Despite the big 5-0-0, I’m going to treat this like a regular episode. Thanks to Dylan, Emily, and Michelle, Remy and Julien, and Rosie for their suggestions this week! We’ll start with Dylan, Emily, and Michelle, who live in Australia. A while back now they got to visit the Australia Zoo, which is run by the Irwin family. Steve Irwin was a conservationist, science educator, and wildlife rehabilitator, also known as the Crocodile Hunter for his work relocating crocodiles who were endangering people, and vice versa. He died tragically young in 2006 but his wife and children continue his work. Michelle pointed out that Irwin has been honored by scientists who have named newly discovered animals for him, so let’s learn about a few of them! The most recent one is a type of wolf snake discovered on the Great Nicobar Island off the coast of India and described in 2025, Lycodon irwini. It’s mostly black in color with a slender body, and can grow as much as 47 inches long, or 119 cm. That’s almost four feet long! Luckily it’s non-venomous, plus it has only been found on that one island in evergreen forests, so you’re not likely to run across one by accident. It probably eats small animals like frogs, but we don’t know a whole lot about it yet. Back in 1990, Steve Irwin caught a strange turtle while fishing with his father, Bob, who was also a conservationist. Between them, the two men knew a whole lot about Australian wildlife but they didn’t know what the turtle was. They sent pictures to a turtle expert, who determined that yes, it was a species new to science. It was described in 1997 and named Irwin’s turtle, Elseya irwini. Irwin’s turtle has a black and yellow carapace and lives in the lower part of the Burdekin River in northern Queensland. The female also has a light-colored head and other pale spots on the body. Like some other turtles, it can absorb oxygen from the water through its cloaca, which is often referred to as its butt. A chamber at the end of the cloaca contains structures that act like gills and absorb oxygen. This allows it to stay underwater longer, and in fact it can’t survive in water that doesn’t contain enough oxygen. As a result, Irwin’s turtle is endangered due to habitat loss, especially from pollution and the damming of its river home. It used to be common but its numbers are in decline. The Australia Zoo started a captive breeding program to help conserve the species, and in 2023 they succeeded in hatching the very first Irwin’s turtle babies ever bred in captivity. The last one is my favorite, a land snail named after Steve Irwin. It was described as a new species in 2009, only a few years after Irwin died, and was named Crikey steveirwini. It’s the only species in the genus Crikey. It only lives in high altitudes in the tropical rainforests of northeastern Queensland. It’s rare and not much is known about it, because it’s so hard to find and so small. It has a cone-shaped shell that’s striped with spiral bands of brown, yellow-brown, and white, and it only grows 15 mm long at most. <p class="west

Episode 499: The Mystery of Amiskwia
Further reading: Cambrian Explosion Month #18: Stem-Gnathifera Ambiguous Amiskwia Amiskwia, possibly [picture taken from above link]: Show transcript: Welcome to the Patreon bonus episode of Strange Animals Podcast for May 2025! We’ve talked about a lot of strange and mysterious animals from the Cambrian in past episodes, especially episode 69, but I don’t think we’ve learned about Amiskwia yet. For a long time it was another mystery animal from the Burgess Shale and a few other places, dating back as much as 518 million years ago, but as of only a few years ago the mystery seems to be solved, at least mostly. Amiskwia grew about an inch long, or 2.5 cm, which actually made it one of the larger animals that lived in the Cambrian. It probably looked superficially like a slug, with a slightly flattened body and a pair of short tentacles on its head. It had a paddle-shaped tail and two flaps on its sides that probably acted as fins to help it swim. Its mouth was on the underside of its head and was surprisingly complicated, with two pairs of plates with little spikes on them. We even know about its internal anatomy, since some of the Amiskwia fossils are so well preserved that its insides can be studied too. It had a brain and a simple digestive tract. Amiskwia was described in 1911 by Charles Walcott, who described a lot of the Burgess Shale fossils. Walcott classified it as a type of arrow worm. When scientists gave it a closer look later, not everyone agreed it was related to modern arrow worms. Some suggested it might be a type of ribbon worm, or maybe an early mollusk, while others argued that it was so different from known animals that it belonged in its own phylum. A 2019 study suggested that Amiskwia’s weird mouth plates matched up with the mouth plates in a living animal, and a 2022 follow-up study confirmed the 2019 findings. Not everyone agrees, but as of now, Amiskwia is considered an ancestral gnathiferan. There! Mystery solved! Wait, what do you mean you don’t know what a gnathiferan is? As everyone knows, especially me, I definitely didn’t just learn about this type of animal myself just now, gnathiferans include a lot of different animals with complex jaws—not like your own jaws, but with little plates and spikes and moving parts made of chitin. Most gnathiferans are tiny, microscopic or barely a few millimeters long, so Amiskwia was a giant in comparison. Arrow worms are also generally considered to be gnathiferans, so Wolcott wasn’t too far off in his description of Amiskwia. We don’t know what Amiskwia ate, but it could probably swim pretty well and most likely hunted other animals or scavenged already dead ones. Scientists think it probably spent most of its time swimming well above the sea floor, which is why it’s a relatively rare fossil. Another Cambrian mystery animal that lived even earlier than Amiskwia, around 520 million years ago, and which is probably related to it, is Timorebestia. Its fossils were discovered in Greenland and only described in 2024. It had a pair of long tentacles or antennae, a rounded paddle-like tail, and fins on each side of its wide, flattened body. Its tentacles were around half the length of its body–and if Amiskwia was a giant compared to modern gnathiferans, Timorebestia was a colossus! It grew almost 8 inches long, or over 20 cm, not even counting its tentacles! Some Timorebestia specimens are so well preserved that scientists can identify what they ate right before they died, and it looks like they mostly ate small arthropods. Timorebestia was probably the biggest and strongest predator in the area when it was alive, one of the earliest apex predators discovered. Another similar animal was Nectocaris, which has been discovered in the Burgess Shale of Canada and other Cambrian fossil sites in China and Australia. It was flattened and had a pa

I’m your host, Kate Shaw. As I’ve mentioned before, I really don’t like April Fools Day, which is April first. I especially don’t like it when someone makes an April fools day post online and just leaves it there afterwards. It’s too easy for other people to stumble across it and think it’s real. This goes double for strange animal and cryptid reports. I subscribe to geologist Sharon Hill’s Pop Goes the Cryptid articles, and on March 31 she talked about a hoax called the North American Pine Squid. It got popular around Halloween of 2024. It’s said to be a black squid or octopus that lives in pine trees in remote, heavily forested places like the Pacific northwest and the Appalachian mountains. Most of the time it eats small animals like birds and squirrels, along with pine cones, but if someone walks underneath its tree, the pine squid grabs the person, pulls them up into the tree, and they’re never seen again. But you don’t have to worry, because the pine squid isn’t a real animal. It’s also not even a new story. It’s based on another hoax called the Pacific Northwest tree octopus, which dates back to 1998. In the case of the tree octopus, it wasn’t created as a hoax or an April fool’s joke but as a study about whether children can tell if a website is reliable or not. The researchers made a page with information about a type of octopus that lived in the ocean but that also climbed trees. Then they asked several classrooms of children around age 11, from different schools in different countries, to read the page, look at the pictures provided, and answer some questions. The study found that most of the children thought the page contained reliable information. Only a few figured out that the tree octopus wasn’t real. The study has been used repeatedly to argue that children need more lessons in how to evaluate a website to know if it contains reliable information, and of course that’s always a good thing. But it makes me a little angry too, because how were the kids supposed to know that octopuses can’t climb trees? There are so many amazing and strange animals out there, a tree octopus sounds perfectly normal if you don’t know very much about octopuses. So I argue that kids should be taught about everything, and taught in as interesting a way as possible so that they remember it better. The same goes for adults. But this episode isn’t actually about April fools day, tree octopuses, or pine squids. It is about a type of octopus, and what I’m going to tell you is so weird that I have to reassure you that it’s actually true. It’s not a hoax or an April fools joke or anything like that. It’s about the gloomy octopus and the underwater cities some populations have created, referred to as Octopolis and Octlantis. I swear I’m not making this up! The gloomy octopus lives off the eastern coast of Australia and the northern coast of New Zealand. It’s mainly brown and gray, but it has orange on the undersides of its arms, and it’s covered in little bumps that help camouflage it. Its eyes are white. On average, it has an armspan of about 6 ½ feet, or 2 meters, with females generally larger than males. Like many other octopuses, when the female lays her eggs, she stops eating completely and protects the eggs until they hatch. After they hatch, she dies. The gloomy octopus lives in shallow warm water and especially likes places with lots of rock
