Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

It’s the 2022 discoveries episode, where we learn about some of the animals discovered in 2022! Most of the time these animals were actually discovered by scientists before 2022, but the description was published in that year so that’s when we first learned about them. And, of course, a lot of these animals were already known to the local people but had never been studied by scientists before. There are lots of animals in the world but not that many scientists.

The great thing is, so many animals get discovered in any given year that I have to pick and choose the ones I think listeners will find most interesting, which in a stunning coincidence turns out to be the ones that I personally find most interesting. Funny how that works out.

We’ll start in the ocean, which is full of weird animals that no human has ever seen before. It’s about a hermit crab who carries a friend around. The hermit crab was already known to science, but until a team of scientists observed it in its natural habitat, the deep sea off the Pacific coast of Japan, no one realized it had an anemone friend.

The sea anemone is related to jellyfish and is a common animal throughout the world’s oceans. Some species float around, some anchor themselves to a hard surface. Many species have developed a symbiotic relationship with other animals, such as the clownfish, which is sometimes called the anemonefish because it relies on the anemone to survive. Anemones sting the way jellyfish do, but it doesn’t sting the clownfish. Researchers aren’t sure why not, but it may have something to do with the clownfish’s mucus coating. Specifically, the mucus may have a particular taste that the anemone recognizes as belonging to a friend. If the anemone does accidentally sting the clownfish, it’s still okay because the fish is generally immune to the anemone’s toxins.

The clownfish lives among the anemone’s tentacles, which protects it from predators, and in return its movements bring more oxygen to the anemone by circulating water through its tentacles, its droppings provide minerals to the anemone, and because the clownfish is small and brightly colored, it might even attract predators that the anemone can catch and eat.

Anemones also develop mutualistic relationships with other organisms, including a single-celled algae that lives in its body and photosynthesizes light into energy. The algae has a safe place to live while the anemone receives some of the energy from the algae’s photosynthesis. But some species of anemone have a relationship with crabs, including this newly discovered anemone.

The anemone anchors itself to the shell that the hermit crab lives in. The crab gains protection from predators, who would have to go through the stinging tentacles and the shell to get to the crab, while the anemone gets carried to new places where it can find more food. It also gathers up pieces of food that the crab scatters while eating, because crabs are messy eaters.

The problem is that hermit crabs have to move into bigger shells as they grow. Anemones can move, but incredibly slowly. Like, snails look like racecar drivers compared to anemones. The anemone moves so slowly that the human eye can’t detect the movement.

What the team of scientists witnessed was a hermit crab spending several days carefully pushing and pinching the anemone to make it move onto its new shell. If it wasn’t important, the crab wouldn’t bother. The sea anemone hasn’t yet been officially described since it’s still being studied, but it appears to be closely related to four other species of anemone that also attach themselves to the shells of other hermit crab species.

In other marine invertebrate news, a researcher named Jeff Goddard was turning rocks over at low tide at Naples Point, California a few years ago. He was looking for sea slugs, but he noticed some tiny clams. They were only about 10 mm long, but they extended a white-striped foot longer than their shells. Goddard had never seen anything quite like these clams even though he was familiar with the beach and everything that lived there, so he took pictures and sent them to a clam expert. The expert hadn’t seen these clams before either and came to look for the clams in person. But they couldn’t find the clams again. It took ten trips to the beach and an entire year before they found another of the clams.

They thought the clam might be a new species, but part of describing a new species is examining the literature to make sure the organism wasn’t already described a long time ago. Eventually the clam research team did find a paper with illustrations of a clam that matched, published in 1937, but that paper was about a fossilized clam.

They examined the 1937 fossil shell and compared it to their modern clam shell. It was a match! But why hadn’t someone else noticed these clams before? Even Goddard hadn’t seen them, and he’s a researcher that spends a lot of time along the coast looking specifically for things like little rare clams. Goddard thinks the clam has only recently started extending its range northward, especially during some marine heatwaves in 2014 through 2016. He suspects the clam’s typical range is farther south in Baja California, so hopefully a future expedition to that part of the Pacific can find lots more of the clams and we can learn more about it.

We talked about deep-sea isopods just a few weeks ago, in episode 311. They’re crustaceans related to crabs and lobsters, but also related to roly-polies that live on land. The deep-sea species often show deep-sea gigantism and are referred to as giant isopods, and that’s what this newly discovered species is. It was first found in 2017 in the Gulf of Mexico and is more slender than other giant isopods. The largest individual measured so far is just over 10 inches long, or 26 cm, which is almost exactly half the length of the longest giant isopod ever measured. It’s still pretty big, especially if you compare it to its roly-poly cousins, also called pillbugs, sow bugs, or woodlice, who typically grow around 15 mm at most.

Before we get out of the water, let’s talk about one more marine animal. This one’s a mystery that I covered in the October 2022 Patreon episode. It was suggested by my brother Richard, so thank you again, Richard!

On August 30, 2022, a research team was off the coast of Puerto Rico, collecting data about the sea floor. Since the Caribbean is an area of the ocean with high biodiversity but also high rates of fishing and trawling, the more we can learn about the animals and plants that live on the sea floor, the more we can do to help protect them.

When a remotely operated vehicle dives, it sends video to a team of scientists who can watch in real time and control where the rover goes. On this particular day, the rover descended to a little over 1,300 feet deep, or around 407 meters, when the sea floor came in view. Since this area is the site of an underwater ridge, the sea floor varies by a lot, and the rover swam along filming things and taking samples of the water, sometimes as deep as about 2,000 feet, or 611 meters.

The rover saw lots of interesting animals, including fish and corals of various types, even a fossilized coral reef. Then it filmed something the scientists had never seen before. It was a little blue blob sitting on the sea floor.

The blue blob wasn’t moving and wasn’t very big. It was shaped roughly like a ball but with little points or pimples all over it and a wider base like a skirt where it met the ground, and it was definitely pale blue in color.

Then the rover saw more of the little blue blobs, quite a few of them in various places. The scientists think it may be a species of soft coral or a type of sponge, possibly even a tunicate, which is also called a sea squirt. All these animals are invertebrates that don’t move, which matches what little we know about the blue blob.

The rover wasn’t able to take a sample from one of the blue blobs, so for now we don’t have anything to study except the video. But we know where the little blue blobs are, so researchers hope to visit them again soon and learn more about them.

It wouldn’t be a newly discovered species list without at least one new frog. Quite a few frogs were discovered in 2022, including a tree frog from Vietnam called Khoi’s mossy frog. It lives in higher elevations and is pretty big for a tree frog, with a big female growing over 2 inches long, or almost 6 cm, from snout to vent. Males are smaller. It’s mostly brown and green with little points and bumps all over that help it blend into the moss-covered branches where it lives. That’s just about all we know about it so far.

Our next discovery is an invertebrate, a spider that lives in bamboo. Specifically it lives in a particular species of Asian bamboo in Thailand, and when I say it lives in the bamboo, I mean it really does live inside the bamboo stalks. Also, when I say it’s a spider, specifically it’s a small tarantula.

It was first discovered by a YouTuber named JoCho Sippawat, who travels around his home in Thailand and films the animals he sees. I watched a couple of his videos and they’re really well done and fun, and he’s adorable even when he’s eating gross things he finds, so I recommend his videos even if you don’t speak the language he speaks. I’m not sure if it’s Mandarin or another language, and I’m not sure if I’m pronouncing his name right either, so apologies to everyone from Thailand for my ignorance.

Anyway, Sippawat found a tarantula where no tarantula should be, inside a bamboo stalk, and sent pictures to an arachnologist. That led to a team of scientists coming to look for more of the spiders, and to their excitement, they found them and determined right away that they’re new to science. It was pretty easy to determine in this case because even though there are more than 1,000 species of tarantula in many parts of the world, none of them live in bamboo stalks. The new spider was placed in a genus all to itself since it’s so different from all other known tarantulas.

It’s mostly black and dark brown with narrow white stripes on its legs, and its body is only about an inch and a half long, or 3 1/2 cm. It can’t make holes into the bamboo plants itself, so it has to find a hole made by another animal or a natural crack in the bamboo. It lines its bamboo stalk with silk to make a little home, and while there’s a lot we don’t know yet about how it lives, it probably comes out of its home to hunt insects and other small animals since tarantulas don’t build webs.

Finally, let’s wrap around to the sea anemone again, at least sort of. If you remember episode 129, we talked about the Venus flytrap sea anemone, which is an animal that looks kind of like a carnivorous plant called the Venus flytrap. We then also talked about a lot of other carnivorous plants, including the pitcher plant. Well, in 2022 a new species of pitcher plant was discovered that has underground traps.

The pitcher plant has a type of modified leaf that forms a slippery-sided pitcher filled with a nectar-like liquid. When an insect crawls down to drink the liquid, it falls in and can’t get out. It drowns and is dissolved and digested by the plant. Almost all known carnivorous plants are pretty small, but the largest are pitcher plants. The biggest pitcher plant known is from a couple of mountains in Malaysian Borneo, and its pitchers can hold over 2 ½ liters of digestive fluid. The plant itself is a messy sort of vine that can grow nearly 20 feet long, or 6 meters. Mostly pitcher plants just attract insects, especially ants, but these giant ones can also trap frogs, lizards, rats and other small mammals, and even birds.

The newly discovered pitcher plant grows in the mountainous rainforests of Indonesian Borneo and is relatively small. Unlike every other pitcher plant known, its pitchers develop underground and can grow a little over 4 inches long, or 11 cm. Sometimes they grow just under the surface, with leaf litter or moss as their only covering, but sometimes they grow deeper underground. Either way, they’re very different from other pitcher plants in other ways too. For one thing, scientists found a lot of organisms actually living in the pitchers and not getting eaten by the plant, including a new species of worm. Scientists aren’t sure why some animals are safe in the plant but some animals get eaten.

The new pitcher plant is found in parts of Indonesian Borneo that’s being turned into palm oil plantations at a devastating rate, leading to the extinction or threatened extinction of thousands of animal and plant species. The local people are also treated very badly. Every new discovery brings more attention to the plight of the area and makes it even more urgent that its ecosystems are protected from further development. The fastest way to do this would be for companies to stop using so much palm oil. Seriously, it’s in everything, just look at the ingredients list for just about anything. I try to avoid it when I’m grocery shopping but it’s just about impossible. I didn’t mean to rant, but the whole palm oil thing really infuriates me.

You know what? Let’s have one more discovery so we don’t end on a sour note.

A biodiversity survey of two of Australia’s marine parks made some really interesting discoveries in 2022. This included a new species of hornshark that hasn’t even been described yet. It’s probably related to the Port Jackson shark, which grows to around five and a half feet long, or 1.65 meters, and is a slow-moving shark that lives in shallow water off the coast of most of Australia. Instead of a big scary mouth full of sharp teeth, the Port Jackson shark has a small mouth and flattened teeth that allow it to crush mollusks and crabs. The newly discovered shark lives in much deeper water than other hornsharks, though, around 500 feet deep, or 150 meters.

Another thing they found during the survey wasn’t a new species of anything, but it’s really cool so I’ll share it anyway. It was a so-called shark graveyard over three miles below the ocean’s surface, or 5400 meters. The scientists were trawling the bottom and when they brought the net up to see what they’d found, it was full of shark teeth–over 750 shark teeth! They were fossilized but some were from modern species while some were from various extinct species of shark, including a close relative of Megalodon that grew around 39 feet long, or 12 meters. No one has any idea why so many shark teeth are gathered in that particular area of the sea floor.

Welcome to Strange Animals Podcast. 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, the Taíno, incorporated the frog into their legends, and there’s even 700-year-old cave art on nearby Mona Island that includes paintings of coquí frogs.

The coquí frog mostly eats small invertebrates, including lots of cockroaches and other beetles, so they’re good to have around. Unfortunately, as is the case with so many frog species around the world, their numbers are in decline due to habitat loss, climate change, pollution, introduced predators, and a deadly fungus that we talked about in episode 250. Studies have shown that some populations of the coquí show a natural resistance to the fungus, so if we can just protect their habitats, the frogs will be okay.

Next, Henry wanted to learn more about the glass frog, which lives in Central and South America. We’ve talked about it very briefly in episode 148 and a couple of old Patreon episodes, but we’ve never really gone in-depth about it. Let’s do that now, because this is a really weird and interesting frog!

The glass frog lives in forests of Central and South America, mostly in treetops. They’re small frogs, no longer than about three inches, or 7.5 cm, from snout to vent. Most species are bright green, and in many species, the belly skin is almost completely transparent. You can see right through to their insides: guts, blood vessels, even bones. One newly discovered species from the Amazon also has a translucent chest so you can see its heart. In some species, even the organs are translucent. Some species even have green bones.

The blue-green color of the bones comes from high levels of biliverdin [bill-uh-ver-din] in the blood, which has evolved at least 40 times in 11 different frog families, with more species that have blue-green blood and bones discovered all the time.

In most animals, high levels of biliverdin are a result of liver disease, since it’s a toxin, but in these frogs, the biliverdin is retained in the blood instead of filtered out by the kidneys. Researchers think the biliverdin serves two purposes. Because it makes the frog green all the way through, it helps camouflage the frog among the leaves where it lives, even in infrared light. Researchers recently discovered that at least two species of glass frog reflect infrared light, which may also help keep them concealed from predators that can see in infrared. The high levels of biliverdin may also make the frog taste bad. Some researchers also think it may help protect the frog from parasites.

This doesn’t appear to be related to their see-through tummies, though. No one’s sure why glass frogs are see-through from underneath. Most species have green backs, which helps them blend in to the leaves they live on. Since the glass frog’s legs are usually partially transparent along with its belly, one study has determined that it’s actually the legs that help with camouflage. When the frog sits on a leaf with its legs folded up on either side, the way frogs often sit, the color of the leaf is partially visible through the legs. This helps make the frog look less frog-shaped since its edges sort of blend in with the leaf.

Most of the time glass frogs live high in the treetops, but during breeding season they come down closer to the ground. The female lays her eggs on leaves hanging over running water, which the male fertilizes. In some species, males guard the eggs until they hatch. When the eggs hatch, the tadpoles drop into the water.

Not all glass frogs have translucent undersides, though. Most are ordinary-looking frogs that may be green or occasionally brown or orangey in color, sometimes with little spots. There are also probably a whole lot more of these frogs than scientists know about, since they live in such hard-to-study areas. Several new species have been discovered in just the last few years, including one rediscovery of a species called Laura’s glass frog.

Until a few years ago, the only specimen of Laura’s glass frog was a male collected in 1955 in the foothills of the Andes Mountains in Ecuador. Then a team of scientists studying frogs in the Colonso-Chalupas Biological Reserve, also in Ecuador, found two frogs that weren’t familiar to them. One was male and the other a young female, both living near small creeks where lots of other frog species were common. They were green with tiny yellow spots surrounded by black rings, and were only a few centimeters long, or less than an inch. After several years of study, the team determined that the frogs were Laura’s glass frogs, and they published their findings almost exactly one year ago, in December 2021.

Hopefully, in 2023 scientists will discover and rediscover even more frog species, and we’ll be able to learn more about them so they and their habitats can be protected.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

It’s finally Halloween, and it’s also our 300th episode! Wow! I don’t think I’ve ever made 300 of anything before. To celebrate, this episode is going to be our most Halloween-y yet, a solid five out of five ghosts on our spookiness scale. Beware, muahahaha!

As usual in our Halloween episodes, we have a little bit of housekeeping before we start. The Beyond Bigfoot & Nessie book is still available everywhere you order books. I have six or seven copies of the paperback if you want to buy a signed copy directly from me. Just drop me an email if you’re interested.

This past year has been extremely busy for me. Apart from the podcast, I also sold my house and moved to an apartment, went to a lot of conventions to sell books, and worked on my fiction writing. I self-published a novella this summer called Royal Red, which is about dragons, but it’s not appropriate for younger readers so I won’t link to it. Everything I’ve done this year has been positive ultimately, but it was incredibly stressful at the time. Now that things are settling down, I’ve had time to think about what I want to do in the future.

I love making Strange Animals Podcast, but it’s also taking up more and more of my time. I have a lot of hobbies and interests outside of podcasting, which I haven’t had time to do very much in the last few years. I need to pull back and regain time for myself. But don’t worry, we’ll still have an episode every week! The episodes will just be shorter on average. Hopefully you won’t even notice the change.

Feel free to continue sending in your suggestions and feedback. I know I’m really backed up on suggestions and hope to get to a bunch of them in the next few months. If you worry that I never got your suggestion, you can send it again! Also, if you want a sticker, send me your mailing address and I’ll mail you one. That’s true all the time, not just right now.

Thanks to everyone for supporting the podcast over the last 300 episodes! Let’s aim for another 300. Also, stick around to the very end of the episode to hear a promo from a great podcast called Bring Birds Back. I think you’ll really like the show.

Now, it’s time to learn about the LOVELAND FROG. Which does not sound spooky, but believe me, it is.

The story doesn’t start in 2016, but that’s where we’re going to start. In early August 2016, a young man named Sam Jacobs was playing Pokemon Go with his girlfriend in Loveland, Ohio. They were near Lake Isabella when Sam noticed a big frog in the water. It was getting dark at this point and all Sam could see was the frog’s eyes reflecting light and its head and back above the water. It was so big that he took pictures and even video, but then the frog stood up out of the water and walked around on its hind legs, the size of a human.

But that wasn’t the first time someone had seen a giant frog-man in the area. In 1972 it was seen twice, both times by policemen.

On March 3, 1972, a policeman named Ray Shockey was driving along Riverside Road at about one in the morning. This was just outside Loveland, Ohio, and as the road’s name implies, the road followed along the Little Miami River. Officer Shockey saw what he initially thought was a dog in the road, but as he came closer, the animal stood up on its hind legs. He said it was about four feet tall, or 1.2 meters, with a face that looked like a frog’s or a lizard’s. Its skin looked leathery but textured. The creature stared at the car for a moment, then jumped over a guard rail and down toward the river.

Shockey was shocked, naturally, and hurried to the station. He told another officer on duty about what he’d seen, Mark Matthews, and the two returned to the spot where Shockey had encountered the creature. They found what looked like scrape marks on the ground leading down to the river, but nothing else.

A few weeks later, Mark Matthews saw the creature himself. He was driving along the river when he saw what he thought was a dead animal on the road. He stopped to move it off the road when it sat up, hurried to the guard rail and climbed over it. Officer Matthews shot at the creature but either missed, or the animal wasn’t hurt badly enough to stop.

But this still isn’t the first time the creature was sighted. We have to go back to 1955 for the first sighting of the creature now known as the Loveland frog or the Loveland frogman. There are various versions of the story but in general, in May of 1955, a businessman named Robert Hunnicott was driving along the Little Miami River at about 3:30 in the morning and saw three strange creatures standing on their hind legs. He was so shocked that he stopped his car to get a better look.

The creatures were no more than 4 feet tall, or 1.2 meters, and had gray leathery skin and faces like frogs. Instead of hair, the skin on their heads was deeply wrinkled. He also noticed they had webbed hands and feet. As Hunnicott stared, one of the figures raised a wand over its head and sparks shot out of it. At this point Hunnicott decided it was time to go, and he drove away quickly.

So, you have to admit, this is a truly spooky event. It may be the spookiest thing we’ve ever discussed on this podcast. But things aren’t all that they seem, so let’s revisit all three stories and learn a little more.

If you read the Wikipedia entry for the Loveland frog, at least as of late October 2022, under the “Popular culture” heading it discusses the 2016 sighting and finishes “It was later revealed to be a local student from Archbishop Moeller High School in a homemade frog costume.” This statement cites as its source a November 13, 2020 article written by a student for the Moeller Crusader, the high school’s newspaper.

But if you actually read the article, which I’ve linked to in the show notes, you’ll notice that it’s meant to be funny. For instance, this paragraph, which purports to be a quote from a student called Jim:

“‘I’ve been obsessed with the Loveland frog since I was a little boy,’ said Jim. ‘He’s like my idol. I dress up as him and go to the tunnel and hop around a few times a week. I sometimes make little chocolates shaped as flies and I’ll eat them while I hop around. And no, I don’t think it’s weird.’”

This actually made me laugh. But nowhere in the article does it state that “Jim” was in the lake in 2016 while Sam Jacobs and his girlfriend were playing Pokemon Go. If Jim was an Archbishop Moeller High School student in November 2020 when the article was published, he would not have been a high school student in August 2016 unless he had to stay in high school for five years instead of the usual four. Either that or he started wearing his costume around in middle school but was only seen once until the article ran in 2020. Also, in the pictures accompanying the article, the frog costume is just an oversized head made of plush fur, not the sort of thing you’d want to wear into a lake and not matching the size of the creature photographed in 2016. Anyway, as I said, the article is clearly meant to be funny, not factual.

In other words, while Wikipedia is a perfectly good source of general knowledge on a topic, make sure you double-check the references cited for accuracy, and don’t use Wikipedia as your only source.

All that aside, it’s a good possibility that the 2016 sighting was a hoax. The pictures and video are grainy since it was dark out, so basically all you can see is what seems to be a dark green or gray human-like figure standing in the water about waist-deep. The glow of its eyes is so bright they look like LED lights instead of the normal eyeshine of a nocturnal or crepuscular animal. The lights also appear to be white. White eyeshine is generally only found in fish, while frogs generally have green eyeshine. Of course, the Loveland frog isn’t actually a frog, and if it is something new to science it could potentially have any color of eyeshine. But such bright white eyeshine is more likely to be due to an artificial light source causing the glow, not the reflection of light.

Let’s go back to the 1972 sightings next. The initial sighting made by Ray Shockey happened in early March. Loveland is a community on the outskirts of Cincinnati, Ohio, and according to online weather history archives, the temperature dipped down to 24 degrees Fahrenheit that night, or -4 Celsius. The following day, Saturday, the temperature only reached 39 F, or 4 C.

It was also windy, which would make it feel even colder.

The Cincinnati Post newspaper reported on the sighting in a March 27, 1972 article. The article takes a humorous tone but it does have some solid reporting, so I’m going to quote a lot of it.

“Patrolman Ray Shockey, 23, was cruising along the river late at night when he saw ‘an animal two to three feet tall with dark green or blackish scaly skin.’ The thing ducked over the bank into the river.

“Ten days ago, Patrolman Mark Matthews, 21, was driving home from duty along the same road at 6 a.m. Near Loveland’s city limits, a good quarter mile from the first sighting but still close to the river, he saw ‘the same type of creature’ and was able to partially swing his headlights on it.

“Matthews said the irritated monster ‘stuck its tongue out at me…it was forked like a serpent’s.’ He fired three shots, apparently missing, and the monster skedaddled towards the water. He estimated the thing as two to four feet high.”

Now we have some real details! The article ends with a quote from a local zookeeper, who noted that the sketch the two officers had made from their reports resembled The Creature from the Black Lagoon, a monster movie that had only been released the year before.

The forked tongue is a telling detail, because there’s a particular animal that mostly fits the creature’s description that does have a noticeable forked tongue. That’s the monitor lizard, and we’ve talked about various monitors in lots of past episodes. Monitor lizards are popular pets in the United States and can easily grow three or four feet long, or 91 to 122 cm. The monitor’s snout is relatively blunt and can look frog-like, although it’s at the end of a relatively long neck. It also has a long tail, so while some details fit the sightings, it’s not a perfect match.

Besides, the monitor lizard is a reptile, and therefore cold-blooded, or ectothermic, meaning its internal body temperature depends on the temperature outside. It can’t function well in cold temperatures and will die if it gets too cold. The same is true of frogs and other amphibians, for that matter, many of which hibernate in burrows, crevices in rocks or logs, and other places protected from freezing temperatures.

It was warmer when Matthews spotted the creature on March 17, 1972, although still not much above freezing. The high temperature that day was 48 F, or almost 9 C, but at 6am it was probably colder. That’s still really cold for a reptile or amphibian to be out and about in the dark.

But that’s not all, because in 2016, after Sam Jacobs and his girlfriend saw the Loveland frog, Mark Matthews contacted the Cincinnati news station WCPO and his story had changed a lot in the 44 years since his own sighting. Even the spelling of his name had changed, with Matthews spelled with one T instead of two, but the 2-T spelling might have been a mistake in the original reports from 1972.

In his 2016 interview, Matthews now said he “was driving on Kemper Road near the boot factory when he saw something run across the road. However, it wasn’t walking upright and didn’t climb over the guardrail as the urban legend of the Frogman goes. The creature crawled under the guardrail. […] ‘I know no one would believe me, so I shot it,’ he said.

“Mathews recovered the creature’s body and put it in his trunk to show Shockey. He said Shockey said it was the creature he had seen, too. It was a large iguana about 3 or 3.5 feet long, Mathews said. The animal was missing its tail, which is why he didn’t immediately recognize it.

“Mathews said he figured the iguana had been someone’s pet and then either got loose or was released when it grew too large. He also theorized that the cold-blooded animal had been living near the pipes that released water that was used for cooling the ovens in the boot factory as a way to stay warm in the cold March weather.”

A big male iguana can get quite large, up to 6 feet long including the tail, or 1.8 meters, and they’re also popular pets. The iguana has a shorter neck than a monitor lizard and a blunt muzzle that could be considered froglike. However, it also has a long tail, a dewlap under the throat, and a row of little spikes down the spine. All these details are distinctive and not reported in the initial reports. It does have a forked tongue, but it’s not noticeable unless you get a good look at it from up close. If Matthews had killed the animal and examined it, he might have seen the tongue and gave that detail to a reporter in 1972, but why didn’t he also mention the spikes and dewlap? If he was trying to protect his fellow officer from ridicule by backing up his story, he didn’t need to stick to details he really saw. He could have made up anything, but instead he just said that the animal stuck a forked tongue at him and ran toward the water.

Besides, it seems awfully convenient that Mark Matthews’s iguana was missing a tail, which would have made it look more froglike, and was active on two nights, one of them below freezing. Iguanas are not nocturnal. It’s also convenient that although he supposedly had the dead animal in his patrol car, he didn’t take any pictures or show anyone except Shockey, who had already died by the time Matthews made his 2016 claim. I don’t think Mark Matthews killed an iguana or anything else that night.

One suggestion is that the animal might have been a mammal with a bad case of mange, which made its skin look like textured leather and made it hard to recognize. But with so few concrete details, no physical evidence, and a witness who changed his story considerably, we can’t even make a guess.

Finally, going back to the 1955 sighting is even more difficult. The best documentation of what happened appears in a publication called Close Encounter at Kelly and Others of 1955, published in 1978 by the Center for UFO Studies. The bulk of the publication is concerned with what’s now called the Kelly-Hopkinsville encounter that happened in Kentucky. I won’t get into the details here because it could and probably one day will be an episode all to itself, but it happened in late August 1955. Part two of Close Encounter at Kelly talks about other strange occurrences that happened not too far away or too long before or after the Kelly-Hopkinsville encounter. According to that publication, the story originally appeared in a September 2, 1955 zine called the CRIFO Orbit, where CRIFO stands for “Civilian Research, Interplanetary Flying Objects.” The editor, Leonard Stringfield, recounts the original article:

“…We should like to cite a case involving a prominent businessman, living in Loveland. Occurring several weeks ago, this person…saw four ‘strange little men about three feet tall’ under a certain bridge. He reported the bizarre affair to the police and we understand that an armed guard was placed there.”

Already we see a lot of discrepancies from the story as it’s usually told these days, but it gets even more complicated and weird. Following that article in the CRIFO Orbit, Stringfield met with another UFO enthusiast who had some corrections to the story. The businessman, he said, was actually a young volunteer policeman. Stringfield went to the chief of police to find out more. He learned the witness’s name, although he only gives his initials, C.F., and that he was 19 years old in either late June or early July 1955 when his sighting took place.

“The witness, C.F., was driving a Civil Defense truck at the time and as he was crossing a bridge in the Loveland area (there is one vehicular bridge into Loveland over the Little Miami River from Clermont County), he noticed four small figures on the river bank beneath the bridge. A terrible smell hung over the area. C.F. immediately drove to police headquarters in Loveland and reported the incident.”

Stringfield next went to talk to C.F., who didn’t really want to discuss his sighting since he’d been laughed at by too many people about it, but he did say that he’d seen “four more-or-less human-looking little men about three feet high,” and that he’d only seen them for about ten seconds. Since this interview took place within a year of the sighting, it’s probably as good as we can get now.

But things get even more complicated, because the very next chapter in the Close Encounter at Kelly publication is titled “The Hunnicutt Encounter at Branch Hill.” Now we have the name seen online attached to the businessman, Robert Hunnicutt, and the date May 25, 1955. Stringfield learned about this sighting from the police chief when they were discussing the other sighting.

The police chief was woken at about four in the morning by someone pounding on his front door. It was Robert Hunnicutt, a short-order cook in a Loveland restaurant, and he looked like he’d seen a ghost. He “told the police chief that while he was driving northeast through Branch Hill (in Symmes Township) on the Madeira-Loveland Pike, he had seen a group of ‘strange little men’ along the side of the road with ‘their backs to the bushes.’ Curious, he had stopped the car and gotten out. …[T]he witness claimed he had seen ‘fire coming out of their hands,’ and that a ‘terrible odor’ permeated the place. When Hunnicutt realized he was looking at something quite out of the ordinary he became frightened; jumping back into his car, he had driven directly to the police chief’s home.”

The chief of police knew Hunnicutt and while he believed the man had had a real fright, he didn’t believe the story as Hunnicutt told it. He also mentioned that Hunnicutt didn’t smell as though he’d been drinking alcohol. The police chief drove out to the spot Hunnicutt described and drove around looking for the creatures, without luck.

You better believe that Stringfield didn’t let this opportunity pass him by. He interviewed Robert Hunnicutt on September 1, 1956.

Hunnicutt said he was out at 3:30am on the night of the sighting because he was driving home from work, and he was driving down a slight hill when his headlights lit up three figures in the grass on the right-hand side of the road. He thought they were people kneeling in the grass for some reason, which is why he stopped his car.

“The figures were short, about three and a half feet in height, and they stood in a roughly triangular position facing the opposite side of the road. […] The forward figure held his arms a foot or so above his head and it appeared to Hunnicutt as though he were holding a rod, or a chain, in this upraised position. […] Sparks, blue-white in color and two or three at a time, were seen jumping back and forth from one hand to the other, just above or below the ‘rod.’ It was Hunnicutt’s impression that the beings were concentrating on some spot directly across the road, although he could see nothing unusual in the woods to the west of the Pike.

“As Hunnicutt got out of the left side of his car, the forward figure lowered his arms and near his feet appeared to release whatever he had been holding. To the witness, ‘it looked as if he tied it around his ankles.’ Then, as Hunnicutt stood by the left side of the car, all three figures simultaneously turned slightly toward their left so that they now faced the witness. Motionless, and without sound or change of expression, they stared directly at him. In the car lights Hunnicutt was able to observe a number of details.

“This most extraordinary trio was made up of three humanoid figures of a greyish color—approximately the same shade of grey for their heads as for their ‘garments.’ ‘Fairly ugly’ were the words Hunnicutt used to describe them. A large, straight mouth, without any apparent lip muscles, crossed nearly the entire lower portion of their faces—an effect which reminded the witness of a frog. The nose was indistinct, with no unusual feature that the witness could discern. The eyes seemed to be more or less normal, except that no eyebrows could be seen. The pate was bald and appeared to have rolls of fat running horizontally across the top, rather like the corregated [sic] effect of a doll’s painted-on hair—except that there was no difference in color.

“The most remarkable feature was the upper torso: the chest was decidedly lopsided. On the right side it swelled out in an unusually large bulge that began under the armpit and extended down to the waist, giving the figures a markedly asymmetrical appearance. The arms seemed to be of uneven length, the right being longer than the left, as though to accommodate this unusual feature. […] Hunnicutt saw nothing unusual about the hands, although he could not say how many fingers they had. […] He could see no feet, but the figures stood in six-inch high grass.”

Hunnicutt described the creatures’ movements as graceful, and he only noticed the smell when he got back into his car and drove off. He described it as “a combination of ‘fresh-cut alfalfa, with a slight trace of almonds,’” which sounds wonderful to me. He also said that a few months later, possibly July or August, he was driving the same stretch of road with his girlfriend and they both noticed the same smell. He stopped, but they didn’t see anything unusual.

After that, the publication goes on to talk about various UFO sightings in the area, so that’s all we have of first-hand accounts of the Loveland frogman.

It’s obvious that people have conflated the two different 1955 sightings, mixing them up so that some retellings repeat information from the original CRIFO Orbit report and others include more information from the Close Encounter at Kelly publication.

Were the creatures aliens, as Stringfield thought? Talking about potential aliens is beyond the scope of this podcast, but I will point out that organisms that evolved on a different planet are unlikely to look anything like humans or other tetrapods. Tetrapods are animals with four limbs of one kind or another, which includes mammals, reptiles, birds, and amphibians on Earth, and apparently also includes most aliens as seen in popular culture. But even on Earth, not every living thing has four limbs—in fact, most things don’t. Just think about jellyfish, octopuses, starfish, spiders, flies, centipedes, slugs, and trees.

But don’t forget about C.F.’s short report about what he saw. We don’t know when his sighting took place but it was probably during the day. All he saw was “four small figures on the river bank beneath the bridge” as he drove over the bridge, along with a terrible smell. He didn’t describe the smell, but most terrible smells near a road are rotting roadkill…and roadkilled animals attract a specific type of bird: vultures. Both turkey vultures and black vultures are common throughout Ohio and surrounding areas, and both are extremely large birds. C.F. didn’t get a good look and was also looking down at them from the bridge as he drove over. Four vultures sitting around a dead animal might easily look like four small human-like figures from a distance, especially when seen at such a strange angle.

As for Hunnicutt’s sighting, remember that it came only a few months after C.F.’s. Both C.F. and Hunnicutt knew the chief of police, so it’s also possible they had other acquaintances in common. C.F. had stopped talking about his sighting after he’d been laughed at by others who didn’t believe him, but it’s possible that Hunnicutt had heard the story. And remember, people see what they expect to see. If Hunnicutt was driving home after a tiring day at work, he might even have fallen asleep, his car drifted to a stop, and he dreamed he met the same weird creatures that C.F. saw.

Then again, I wasn’t there and it’s not fair for me to look back on a secondhand account from 67 years ago and decide that the witness dreamed it all. So we’ll just have to admit that the Loveland frog-man as seen in 1955, 1972, and 2016…might have been something truly strange after all.

Happy Halloween!

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

We’re getting really close to Halloween and our 300th episode, and it’s going to be a spooky one! This week, though, I rate this episode as one ghost out of five on our spookiness scale, meaning it’s not very spooky at all…unless you’re a frog!

Most of us know this story. A worker helping to demolish a building finds a mysterious box hidden in the building’s cornerstone. He opens the box and discovers a living frog—a frog that can sing and dance! But only when no one else is looking!

That’s the classic Looney Tunes cartoon “One Froggy Evening,” and while it’s really funny, it’s also based on many stories about frogs, toads, and other animals supposedly discovered entombed but alive, or only recently dead, in clay, bricks, tree trunks, coal, and even rocks.

For example, in 1782, the American politician and naturalist Benjamin Franklin was living in France, and while he was there he heard about some workmen in a quarry who had found some living toads encased in stone. I’ll quote from Franklin’s writing:

“At Passy, near Paris, April 6th, 1782, being with M. de Chaumont, viewing his quarry, he mentioned to me, that the workmen had found a living toad shut up in the stone. On questioning one of them, he told us, they had found four in different cells which had no communication; that they were very lively and active when set at liberty; that there was in each cell some loose, soft, yellowish earth, which appeared to be very moist. We asked, if he could show us the parts of the stone that formed the cells. He said, No; for they were thrown among the rest of what was dug out, and he knew not where to find them. We asked, if there appeared any opening by which the animal could enter. He said, No. […] We asked, if he could show us the toads. He said, he had thrown two of them up on a higher part of the quarry, but knew not what became of the others.

“He then came up to the place where he had thrown the two, and, finding them, he took them by the foot, and threw them up to us, upon the ground where we stood. One of them was quite dead, and appeared very lean; the other was plump and still living. The part of the rock where they were found, is at least fifteen feet below its surface, and is a kind of limestone. A part of it is filled with ancient seashells, and other marine substances. If these animals have remained in this confinement since the formation of the rock, they are probably some thousands of years old.”

Since limestone generally takes about a million years to form, and requires considerable pressure and lots of chemical reactions to do so, we can be certain that the toads were not in the limestone for all that long. But limestone is porous, and the mention of damp yellow earth inside the capsules of stone suggests that there were significant fissures in the stones where the toads were found. Limestone dissolves in water, although it takes a long time. That’s how caves form. Maybe over many years, tiny cracks and holes had formed in the limestone, large enough for some well developed tadpoles or young toads to end up in the holes, maybe during a rainstorm or flood.

Then again, the whole thing might have been a mistake. The toads might not have actually been inside the stones, only nearby when the stones were broken open. The workers might have thought they were inside. Or it might just have been a hoax made up by a bored quarry worker.

Stories of animals found encased in stone or other impossible conditions go back hundreds of years, in many parts of the world, but for some reason they got really popular around the mid-19th century in England. Suddenly people were finding toads and other animals in all sorts of weird places, or said they had. The Rev. Robert Taylor of St. Hilda’s Church, Hartlepool, for instance, exhibited a toad and the stone it was found in, with the chamber inside the stone being exactly the size and shape of the toad before it was broken open and freed in April 1865. But a geologist who examined the stone found obvious chisel marks where it had been hollowed out and shaped to look like the toad had been inside.

It wasn’t just toads found in rocks, of course, although those were the most popular. A mouse was supposedly found in a rock in 1803, three salamanders of a presumed extinct species were supposedly found in a rock sometime before 1818, and a horned toad was supposedly found in a building cornerstone in 1928. The horned toad is actually a lizard, in this case a Texas horned lizard that lives in various parts of the south-central United States and northeastern Mexico.

The Texas horned lizard does actually resemble a toad in some ways. Its body is broad and rounded and its face has a blunt, froglike snout. A big female grows about 5 inches long, or almost 13 cm, not counting its tail, while males are smaller. It’s covered with little pointy scales, and if it feels threatened, it will puff up its body so that the scales stick out even more. It also has true horns on its head, little spikes that are formed by projections of its skull.

The Texas horned lizard eats insects, especially a type of red ant called the harvester ant. The harvester ant is venomous but the horned lizard is resistant to the venom and is specialized to eat lots and lots of the ants. Its esophagus produces lots of mucus when it’s eating, which collects around the ants and stops them from being able to bite before they die.

The horned lizard supposedly found in a cornerstone of a building was nicknamed Ol’ Rip after Rip Van Winkle, the main character in a short story by Washington Irving who fell asleep and woke up 20 years later. Ol’ Rip the Texas horned lizard was supposedly placed into the hollow cornerstone brick as part of a time capsule when the Eastland County Courthouse was being built in 1897.

In 1928, the courthouse was torn down and a newspaper reporter advertised the opening of the time capsule, including the story about the horned lizard. Sure enough, a live horned lizard was removed from the cornerstone when it was opened, which by the way was the inspiration for the “One Froggy Evening” cartoon.

Ol’ Rip became a celebrity and was displayed all over the United States, and the Texas horned lizard became such a popular pet that the population declined severely, since people went out and caught them to sell as pets. Since the horned lizard eats a lot of insects that damage crops, its decline in numbers actually led to farmers losing money to insect damage. The Texas horned lizard is still endangered, for that matter, and is now a protected species that isn’t allowed to be kept as a pet. Ol’ Rip died less than a year after he was supposedly discovered in the cornerstone.

Even at the time, a lot of people were skeptical that Ol’ Rip had really been in the cornerstone brick for 31 years. It’s much more likely that one of the officials presiding over the time capsule’s opening brought a horned lizard with him and pretended to find it in the brick.

For one thing, the Texas horned lizard needs bright sunshine to survive. Its body can only produce vitamin D when it gets a lot of sunshine, and without vitamin D it will eventually die. It spends a lot of time sunbathing and while it does dig a burrow to sleep in at night, as soon as the sun’s out in the morning, the lizard comes out to bask in the sunshine. A Texas horned lizard trapped in a brick without food, water, air, or sunshine wouldn’t survive long.

The weirdest animal ever supposed to have been found in a stone was reported in the Illustrated London News in 1856. According to the article, during the construction of a railway tunnel in France, a huge block of stone was dislodged with dynamite. The workers were breaking it into smaller pieces when they exposed a chamber inside the rock. A creature emerged that looked something like an enormous bat, but was obviously not a bat. It had a long neck, sharp teeth in its mouth, four long legs with long claws on its talons, and its front and hind legs were connected with flying membranes. It was black with bare skin.

The animal shook its wings but promptly dropped dead, and was sent to a naturalist who identified it as Pterodactylus anas, which had died 64 million years before. Its wingspan was measured as 10 feet, 7 inches across, or 3 meters, 22 cm.

There is no species of pterodactyl named Pterodactylus anas, but anas is Latin for duck. The word for duck in French is canard, which in English means something more like “a hoax or tall tale.”

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we have a short episode about the recent discovery of a mystery frog in Peru–but first, we have TWO birthday shout-outs! That’s twice the fun!

Happy birthday to both Finn and Oran! I hope your birthdays are amazing! Maybe you should each have two birthday parties, one for yourself and one for the other, even though you don’t know each other and your birthdays are actually on different days.

Peru is a country in western South America, and it’s home to the Amazon Basin rainforest and many other habitats. Frogs are common throughout the Amazon, naturally, since there’s a whole lot of water and rain, and it’s warm all the time. One particular genus of frog, Synapturanus, is especially widespread but is hard to find because it spends most of its time underground.

A team of scientists researching the Amazon’s diversity of animals and plants, especially those organisms that are mostly hidden for various reasons, heard about a particular Synapturanus frog known to the people of the area. The frog is nocturnal and lives underground in burrows it digs in the Amazon peatlands.

Peat is wet soil made up mostly of partially decayed vegetation. It’s the first step in the formation of coal beds, but the coal takes millions of years to form whereas peat only take thousands of years to form. Peatlands are really important to the ecological health of the entire earth, because they store so much carbon and absorb so much water.

The scientists knew from locals that this particular frog existed. The next step was to actually find it so they could learn more about it. A small team of scientists from Peru and other countries traveled to the area, and local guides took them to sites where the frog was supposed to live.

Because the frog is nocturnal, they had to go at night to find it. But because the frog also spends most of its time underground, they couldn’t just walk around shining flashlights on frog-shaped things in hopes of finding a new species of frog. Instead, they had to listen.

Many new frog species are only discovered after a frog expert hears a call they don’t recognize. That was the case for this frog. The male makes a loud beeping noise, especially after rain. Whenever one of the scientists heard one, they’d immediately drop to the ground and start digging with their hands. I can’t even imagine how muddy they must have gotten.

It was around 2am on the last night of the search when their digging paid off. A little brown frog hopped out of its disturbed burrow and all the scientists scrambled around in an excited panic to catch it carefully before it got away.

This is what the frog sounds like:

[tapir frog beeping]

The locals call the frog rana danta, which means tapir frog. The tapir, as you may remember from episodes 18 and 245, among others, is a sort of pig-shaped animal with a short trunk-like snoot called a proboscis. It’s distantly related to rhinoceroses and horses. It uses its proboscis to gather plants and spends a lot of time underwater, and will even sink to the bottom of a pond or stream and walk across it on the bottom instead of swimming.

The tapir most common around the Amazon in Peru is the South American tapir. It’s dark brown in color with a tiny little stub of a tail and a shorter proboscis than other tapir species. Its proboscis looks less like a little trunk and more like a long pointy nose.

The tapir frog is chocolate brown in color, has no tail of course because it’s a frog, and while it has a chonky body sort of life a tapir, its nose draws out to a blunt point. It looks remarkably similar in shape to a South American tapir, but in frog form.

The team ended up catching several of the frogs, and genetic studies determined that it is indeed a new species. They described the new frog in February of 2022 and named it Synapturanus danta. Danta is the local word for tapir.

While we still don’t know much about the tapir frog, it probably lives only in the Amazon peatlands and eats worms and small insects it finds underground. The discovery is important because it’s yet another animal endemic to this part of the Amazon. Conservationists are working to preserve the Amazon peatlands habitat from development in order to save all the unique plants and animals that live there. Development is just a fancy term for habitat loss.

The Putumayo Corridor is a proposed conservation area that follows the Putumayo River across Ecuador, Colombia, Peru, and Brazil. Its goal is to keep the river from being dammed and protect it from logging and other invasive development, while allowing local people to manage the land in traditional ways as they have for thousands of years. Hopefully the peatlands will remain undisturbed and the little tapir frog will continue to beep from its underground home for a very long time.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This episode marks our 5th year anniversary! I also finally got the ebook download codes sent to everyone who backed the Kickstarter at that level. The paperback and hardback books will hopefully be ready for me to order by the end of February and I can get them mailed out to backers as soon as humanly possible. Then I’ll focus on the audiobook! A few Kickstarter backers still haven’t responded to the survey, either with their mailing address for a physical book or for names and birthdays for the birthday shout-outs, so if that’s you, please get that information to me!

Anyway, happy birthday to Strange Animals Podcast and let’s learn about some animals new to science in 2021!

It’s easy to think that with all the animals already known, and all the people in the world, surely there aren’t very many new animals that haven’t been discovered yet. But the world is a really big place and parts of it, especially the oceans, have hardly been explored by scientists.

It can be confusing to talk about when an animal was discovered because there are multiple parts to a scientific discovery. The first part is actually finding an animal that the field scientists think might be new to science. Then they have to study the animal and compare it to known animals to determine whether it can be considered a new species or subspecies. Then they ultimately need to publish an official scientific description and give the new animal a scientific name. This process often takes years.

That’s what happened with the emperor dumbo octopus, which was first discovered in 2016. Only one individual was captured by a deep-sea rover and unfortunately it didn’t survive being brought to the surface. Instead of dissecting the body to study the internal organs, because it’s so rare, the research team decided to make a detailed 3D scan of the octopus’s body instead and see if that gave them enough information.

They approached a German medical center that specializes in brain and neurological issues, who agreed to make a scan of the octopus. It turned out that the scan was so detailed and clear that it actually worked better than dissection, plus it was non-invasive so the preserved octopus body is still intact and can be studied by other scientists. Not only that, the scan is available online for other scientists to study without them having to travel to Germany.

The emperor dumbo octopus grows around a foot long, or 30 cm, and has large fins on the sides of its mantle that look like elephant ears. There are 45 species of dumbo octopus known and obviously, more are still being discovered. They’re all deep-sea octopuses. This one was found near the sea floor almost 2.5 miles below the surface, or 4,000 meters. It was described in April of 2021 as Grimpoteuthis imperator.

Oh, and here’s a small correction from the octopus episode from a few years ago. When I was talking about different ways of pluralizing the word octopus, I mispronounced the word octopodes. It’s oc-TOP-uh-deez, not oc-tuh-podes.

Another octopus discovered in 2021 is called the star octopus that has a mantle length up to 7 inches long, or 18 cm. It lives off the southwestern coast of Australia in shallow water and is very common. It’s even caught by a local sustainable fishery. The problem is that it looks very similar to another common octopus, the gloomy octopus. The main difference is that the gloomy octopus is mostly gray or brown with rusty-red on its arms, while the star octopus is more of a yellowy-brown in color. Since individual octopuses show a lot of variation in coloration and pattern, no one noticed the difference until a recent genetic study of gloomy octopuses. The star octopus was described in November 2021 as Octopus djinda, where “djinda” is the word for star in the Nyoongar language of the area.

A study of the bleating tree frog in eastern Australia also led to a new discovery. The bleating tree frog is an incredibly loud little frog, but an analysis of sound recordings revealed that not all the calls were from the same type of frog. In fact, in addition to the bleating tree frog, there are two other really loud frog species in the same area. They look very similar but genetically they’re separate species. The two new species were described in November 2021 as the screaming tree frog and the slender bleating tree frog.

This is what the slender bleating tree frog sounds like:

[frog call]

This is what the screaming tree frog sounds like:

[another frog call]

Another newly discovered frog hiding in plain sight is the Mindoro fanged frog, found on Mindoro Island in the Philippines. It looks identical to the Acanth’s fanged frog on another island but its mating call is slightly different. That prompted scientists to use both acoustic tests of its calls and genetic tests of both frogs to determine that they are indeed separate species.

Lots of insects were discovered last year too. One of those, the hidden alpine moth, ended up solving a 180-year-old scientific mystery that no one even realized was a mystery.

The moth was actually discovered in the 1990s by researchers who were pretty sure it was a new species. It’s a diurnal moth, meaning it’s active during the day, and it lives throughout parts of the Alps. Its wingspan is up to 16mm and it’s mostly brown and silver.

Before they could describe it as a new species and give it a scientific name, the scientists had to make absolutely sure it hadn’t already been named. There are around 5,000 species of moth known to science that live in the Alps, many of them rare. The researchers narrowed it down finally to six little-known species, any one of which might turn out to be the same moth as the one they’d found.

Then they had to find specimens of those six species collected by earlier scientists, which meant hunting through the collections of different museums throughout Europe. Museums never have all their items on display at any given time. There’s always a lot of stuff in storage waiting for further study, and the larger a museum, the more stuff in storage it has. Finding one specific little moth can be difficult.

Finally, though, the scientists got all six of the other moth species together. When they sat down to examine and compare them to their new moth, they got a real surprise.

All six moths were actually the same species of moth, Dichrorampha alpestrana, described in 1843. They’d all been misidentified as new species and given new names over the last century and a half. But the new moth was different and at long last, in July 2021, it was named Dichrorampha velata. And those other six species were stricken from the record! Denied!

You don’t necessarily need to travel to remote places to find an animal new to science. A professor of taxonomy at Virginia Tech, a college in the eastern United States, turned over a rock by the campus’s duck pond and discovered a new species of millipede. It’s about three quarters of an inch long, or 2 cm, and is mostly a dark maroon in color. It’s called the Hokie twisted-claw millipede.

Meanwhile, on the other side of the world on the island of Sulawesi, a team of scientists discovered FOURTEEN different species of shrew, all described in one paper at the end of December 2021. Fourteen! It’s the largest number of new mammals described at the same time since 1931. The inventory of shrews living on Sulawesi took about a decade so it’s not like they found them all at once, but it was still confusing trying to figure out what animal belonged to a known species and what animal might belong to a new species. Sulawesi already had 7 known species of shrew and now it has 21 in all.

Shrews are small mammals that mostly eat insects and are most closely related to moles and hedgehogs. Once you add the 14 new species, there are 461 known species of shrew living in the world, and odds are good there are more just waiting to be discovered. Probably not on Sulawesi, though. I think they got them all this time.

In South America, researchers in central Peru found a new species of wood lizard that they were finally able to describe in September 2021 after extensive field studies. It’s called the Feiruz wood lizard and it lives in the tropical Andes in forested areas near the Huallaga River. It’s related to iguanas and has a spiny crest down its neck and the upper part of its back. The females are usually a soft brown or green but males are brighter and vary in color from green to orangey-brown to gray, and males also have spots on their sides.

The Feiruz wood lizard’s habitat is fragmented and increasingly threatened by development, although some of the lizards do live in a national park. Researchers have also found a lot of other animals and plants new to science in the area, so hopefully it can be protected soon.

So far, all the animals we’ve talked about have been small. What about big animals? Well, in October 2021 a new whale was described. Is that big enough for you? It’s not even the same new whale we talked about in last year’s discoveries episode.

The new whale is called Mesoplodon eueu, or Ramari’s beaked whale. It’s been known about for a while but scientists thought it was a population of True’s beaked whale that lives in the Indian Ocean instead of the Atlantic.

When a dead whale washed ashore on the South Island of New Zealand in 2011, it was initially identified as a True’s beaked whale. A Mātauranga Māori whale expert named Ramari Stewart wasn’t so sure, though. She thought it looked different than a True’s beaked whale. She got together with marine biologist Emma Carroll to study the whale and compare it to True’s beaked whale, which took a while since we don’t actually know very much about True’s beaked whale either.

The end result, though, is that the new whale is indeed a new species. It grows around 18 feet long, or 5.5 meters, and probably lives in the open ocean where it dives deeply to find food.

We could go on and on because so many animals were discovered last year, but let’s finish with a fun one from India. In June of 2020, a graduate student named Virender Bhardwaj was stuck at home during lockdowns. He was able to go on walks, so he took pictures of interesting things he saw and posted them online. One day he posted a picture of a common local snake called the kukri snake.

A herpetologist at India’s National Centre for Biological Sciences noticed the picture and immediately suspected it wasn’t a known species of kukri snake. He contacted Bhardwaj to see where he’d found the snake, and by the end of the month Bhardwaj had managed to catch two of them. Genetic analysis was delayed because of the lockdowns, but they described it in December of 2021 as the Churah Valley kukri snake.

The new snake is stripey and grows over a foot long, or 30 cm. It probably mostly eats eggs.

It just goes to show, no matter where you live, you might be the one to find a new species of animal. Learn all you can about your local animals so that if you see one that doesn’t quite match what you expect, you can take pictures and contact an expert. Maybe next year I’ll be talking about your discovery.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This is our 250th episode, not counting the various bonus episodes, and I should have prepared a special show as a result but I didn’t notice until just now. But let’s pretend this is a special episode 250 show. It’s all about the golden toad.

The golden toad is from a tiny area of Costa Rica in Central America. I really do mean a tiny area. North of the city of Monteverde is the Monteverde Cloud Forest Reserve, and the toad was only known from one small part of the reserve that was less than two square miles in size, or about four square kilometers. Specifically, it’s from a single ridge in the nature reserve.

A cloud forest is a type of high altitude rainforest. Because temperatures tend to be much cooler than in an ordinary rainforest, a cloud forest can look very different and sometimes wonderfully strange. Cloud forests are foggy a lot of the time and the trees are often covered in thick mosses. In some cloud forests the trees are quite small while ferns and other plants can grow extremely large.

The Monteverde Cloud Forest Reserve is home to thousands of plant and animal species, many of them found nowhere else in the world. That includes the golden toad.

The golden toad gets its name from the male’s coloring. The males are a beautiful golden orange while the females are mostly gray or black with yellow, red, or green markings. As in many frogs and toads, females are larger than males, with a big female growing over two inches long from nose to butt, or about 5.5 centimeters.

The golden toad was only discovered by scientists in 1964 and described in 1966. The last golden toad was a male observed in May of 1989 during what should have been the mating season, but he was all alone. The golden toad was declared extinct in 2004 after repeated searches turned up no toads at all.

It’s easy to think that because the golden toad was restricted to such a small area, it was inevitable that it would go extinct, but the toads were actually common throughout their range until suddenly they weren’t. We’re not sure what happened. Here’s the story.

When the toad was first discovered, researchers estimated that there were around 1,500 adult toads living on the ridge. Most of the time the toads were hard to find, since during the dry season, or when they weren’t actively hunting the insects they ate, they’d stay in underground burrows where it was always nice and damp. But when the spring rains started, the males would hop out and gather around shallow puddles at the base of trees. Females would join the males, and because there were always more males than females, they’d all try to be the one to fertilize her eggs. During this time researchers were able to observe and count the toads, which they described as looking like living jewels.

The female golden toad laid her eggs in the pools of rainwater. The eggs hatched quickly but the tadpoles needed to live in their pool for at least four more weeks until they metamorphosed into toadlets that lived on land. If there was too much rain, the pools would overflow and the tadpoles were in danger of being washed out to die. If there wasn’t enough rain, the pools would dry out and the tadpoles would also die. But most years conditions were pretty good and lots of tadpoles lived to grow up. Until 1987.

A behavioral ecologist who specializes in amphibians, Martha Crump, was studying the golden toads in 1987. In April things seemed normal. The females laid their eggs in the shallow pools as usual, but then the rains stopped. The pools dried out and the eggs and tadpoles all died. When it rained again in May, the females laid more eggs and Dr. Crump counted them, because scientists do a lot of counting. She counted about 43,500 toad eggs. But the pools dried up again, and it was sadly easy for Dr. Crump to count how many tadpoles survived. It was only 29.

The next year, in 1988, there were only ten adult golden toads found. In 1989, one golden toad. In 1990 and beyond, zero golden toads.

The unusually dry spring of 1987 was a devastating blow to the golden toad population, but the adults weren’t affected. They had their nice damp burrows to live in and lots of insects to eat. Dry conditions happen every so often but not every year. Obviously something else happened between 1987 and 1988 to kill off almost all the adult toads too.

Researchers couldn’t figure out what might have happened. One hypothesis was that drought caused by the El Niño weather pattern was unusually severe in 1987 and killed off the adults as well as that year’s eggs and tadpoles. Another was that pesticides had found their way into the environment and killed the toads. Many researchers hoped that the toads were actually still alive, just hiding in their burrows until conditions improved, and every spring for many years toad experts waited to see if the living jewels would emerge during the spring rains. But they never did.

At the same time, though, toads, frogs, and other amphibians around the world were declining in numbers and going extinct. A veterinarian named Lee Berger, who was working toward her doctorate degree, discovered why in 1998. It’s a disease called chytridiomycosis, which is caused by a fungus. The disease infects the animal’s skin, and since amphibians absorb water, oxygen, and some essential minerals through their skin, the disease kills them rapidly.

Chytridiomycosis doesn’t kill every frog. Some species are more or less immune to the disease’s effects, but when infected frogs are taken to other places by people, as pets or food or whatever reasons people have for moving frogs around, the disease spreads rapidly. By the time Dr. Berger identified the cause, dozens of species of amphibian had already gone extinct as a direct result of the disease, and it’s continued ever since. The fungus spreads through water, so if a healthy frog moves into an infected pond, it’s likely to contract the disease.

There’s no cure for chytridiomycosis and treatment isn’t always effective. It doesn’t mean all amphibians are doomed, though. Studies of species that show natural immunity reveal that some amphibians have beneficial bacteria on their skin that stops the fungus from infecting it. Frogs from parts of Costa Rica show various levels of resistance to the fungus even though Costa Rica is particularly hard-hit when it comes to the disease.

The fungus especially thrives in cooler areas in high elevations—exactly the kind of place where the golden toad lived. Even so, the golden toad might have survived and developed a resistance to the disease, except for the bad luck of a drought year that killed off all the eggs and tadpoles at the worst possible time.

But while researchers have searched for the golden toad for years without luck, it might still be around. In 1991 one farmer reported seeing a pool full of healthy golden toads in a remote part of the cloud forest, including young toads. Other people have reported sightings too.

The important thing is that the Monteverde Cloud Forest Reserve is still protecting the golden toad’s habitat, along with all the other animals and plants in the reserve. If the golden toad is still hanging on, hopefully with individuals that have developed a resistance to chytridiomycosis, it has a safe place to increase in numbers.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

A few weeks ago I got to meet two listeners, Brad and Dan. We met for coffee and had a great time talking about animals and podcasting and lots of other things. Dan is a podcaster too, cohost of a great show called “Sure, Jan!” which discusses musical theater in detail with a lot of insight and humor. There’s some language not appropriate for kids, but honestly, any kid who’s so into musical theater that they’re listening to a three-part deep dive into “Everybody’s Talking About Jamie,” they can handle a few bad words. There’s a link in the show notes if you want to check it out.

Brad and Dan both gave me topic suggestions, so this is their episode!

We’ll start with Brad’s suggestion about strange dog breeds. We actually covered this topic a few years ago in a Patreon episode, so Patreon subscribers may recognize a lot of this information, but I’ve done some additional research and added to it.

There are a lot more dog breeds out there than most people know, many of them very rare and restricted to particular regions of the world. Often they were bred for specific purposes, sometimes purposes that no longer exist. This is the case for the turnspit dog. It was a short-legged dog that was bred to run on what was called a dog wheel. The dog wheel looked like a big hamster wheel and turned the spit, a metal rod suspended over the fire that a big piece of meat was stuck onto. The dog ran in the wheel, which turned it, which turned the cord attached to the spit, which turned the spit, which meant the meat cooked evenly instead of staying raw on one side and burning on the other. Usually a household had two turnspit dogs so one could rest while the other took a turn running in the wheel. Once better technology was invented to cook meat, the turnspit dogs were out of a job and eventually stopped being bred. They’re now an extinct breed.

Another extinct dog breed is the Talbot hound. It was a large, relatively slow and heavy hound with white or pale-colored fur, popular in Europe for hundreds of years as a hunting dog. It appears on many coats of arms. It was less of a breed than a type of dog, with many large hounds being referred to as talbots as far back as the 15th century and Talbot being a common name for a hound in the 14th century and possibly earlier. By the 17th century it was more of a standardized breed, resembling a white or light-colored bloodhound in appearance with a tail that curled upward. But by the 19th century it had gone extinct. It might have been the ancestor of the modern beagle.

Many dog breeds aren’t all that old, only dating back to roughly the early 19th century. In the Victorian era in Britain, people got really interested in recreating dog breeds from antiquity, so some breeds that people think date back to antiquity were actually developed just a few hundred years ago. But there are some breeds that genuinely have been around and more or less unchanged for a really long time.

The Xoloitzcuintli (sho-lo-eets-quint-lee) or Xolo is a rare breed of dog that was originally bred by the Aztecs and dates back more than 3,500 years. It’s a hairless dog, although many actually do have a full coat. The hairless variety has black or gray-blue skin that is susceptible to sunburn, while the coated variety has short, dense hair. Because hairlessness is genetically related to a condition where not all the teeth form, hairless Xolos usually have fewer teeth than coated Xolos. Hairless dogs need sunscreen and skin care to keep their skin healthy just like people do.

Another old dog breed is the Norwegian Lundehund. It’s a small, active dog bred specifically for hunting puffins. The breed nearly went extinct after a dog tax made it hard for people to afford keeping numerous dogs, and instead they started using nets to hunt puffins. After the puffin was declared a protected species, even the people who still kept lundehunds for hunting stopped breeding them.

By 1963 there were only six purebred lundehunds alive, five of them related to each other. As a result, despite careful breeding guidelines, modern lundehunds are extremely inbred and prone to genetic diseases. Currently a group of breeders and geneticists are working on crossbreeding the Lundehund with other Nordic breeds to retain the lundehund’s unique traits but make it healthier.

The lundehund definitely has unique traits. It has six toes on each foot, has incredibly flexible leg and neck joints, and can fold its ears shut to keep out water and dirt. All these traits helped it climb nearly vertical cliffs and caves where puffins nested. It also has a double coat to help keep it warm in cold weather. But there is good news for the lundehund: it has a job again! In 2013 the dogs started being used to find bird nests around Norwegian airports. Airports need to keep birds away from the flight paths of planes, since if they hit the plane’s windshield or get sucked into the engine’s air intake, they can cause a plane to crash. The lundehunds hunt down bird nests on the airport grounds so they can be removed before there’s a terrible accident.

While I was working on this episode, Richard from NC, who had no idea that I was researching weird dog breeds, asked if I’d heard about the Carolina dog, also known as the American dingo. I looked it up and it’s a real animal—specifically, a dog breed. But it has a strange history.

The Carolina dog is medium-sized, up to 20 inches tall at the shoulder, or 51 cm, but lightly built. Its short hair is often yellow, ginger, or pale brown in color, sometimes with white markings. It has long, slender, erect ears and a long tail. White settlers sometimes called it the Indian dog because Native Americans kept it as a pet or hunting dog, but there were also plenty of feral Carolina dogs living in the wild in the eastern United States.

Archaeological excavations done in the late 19th century found lots of dog remains buried with people. Several archaeologists noted that the dog’s jaw was slightly different from other dog breeds, lacking one pair of teeth. They suggested that the so-called Indian dogs were descended from the earliest domesticated dogs in Asia and migrated into North America when humans did in the Pleistocene.

This was the accepted theory until 2013, when genetic testing was finally done on the breed. Later genetic studies have also been carried out. The studies all conclude that although the Carolina dog has interbred with modern dog breeds, it does have genetic markers that indicate some of its ancestors are from East Asia. It’s more complicated than it sounds, though. A 2018 genetic study compared fossils from ancient North American dogs with the living Carolina dogs and didn’t find much of a match. The fossil dogs migrated from Siberia and were isolated in North America for 9,000 years. Then their unique genetic signature vanished, with the exception of some Arctic dog breeds, as Eurasian dogs brought to North America from Europe took over. Some Carolina dogs do contain that unique genetic signature, but there’s no way to tell if it’s from ancient ancestors or more recent cross-breeding with Arctic breeds.

What is definitely true is that the Carolina dog shares a lot of physical traits with other feral dog populations from around the world. Basically, if dogs are allowed to live and breed without human help or interference, the result is a dog that looks a lot like the Carolina dog of North America, or the pariah dog of Asia, or the dingo of Australia.

But let’s talk now about dogs with double noses, such as the Pachón Navarro, a Spanish hunting dog that sometimes has a double nose, also called a split nose. That doesn’t mean it has two snouts or four nostrils, but that each nostril has its own nose pad separated by a strip of skin and fur, with a groove running down the middle of the snout.

The Pachón Navarro almost went extinct as a breed. A breeding program got underway in the 1970s but it’s still a rare breed. It’s a pointer hound bred since at least the 15th century in the Pyrenees Mountains, and it has short hair that’s white with brown or orange markings, especially on the ears and over the eyes. Not all dogs of this breed have the double nose, and some modern breeders try not to breed for it since the double nose trait is linked to a cleft palate that can cause other health issues.

The double-nosed trait is only seen in one other dog population. The Tarsus Catalburun [chatal-burrun], or Turkish pointer, may be a descendant of Spanish dogs favored by Turkish nobility, or it may be the dog that gave rise to the Pachón Navarro breed. Most historians think the breed was probably developed in the 19th century from European dogs since there has never been a tradition of hunting with pointers in the area. It’s really rare outside of Turkey and rare inside of Turkey, with a population of only a few hundred dogs that are somewhat inbred. They’re mostly kept by partridge hunters.

There is a mystery associated with double-nosed dogs. The Andean tiger hound is a third variety of double-nosed dog that’s supposed to live in Bolivia, South America. It’s supposedly descended from dogs brought to the Americas by Spanish Conquistadors in the 16th century.

But does the Andean tiger hound really even exist? In 1913, explorer Lt.-Col Percy Fawcett reported seeing double-nosed dogs in the Amazon jungle. In a book Fawcett’s son compiled from his field notes and published in 1953, he reports,

“Here we saw for the first and only time a breed of dog known as the double-nosed Andean tiger hound. The two noses are as cleanly divided as though cut with a knife. About the size of a pointer, it is highly valued for its acute sense of smell and ingenuity in hunting jaguars. It is found only on these plains.”

But no one else who visited Bolivia ever reported seeing any of these dogs—until 2005 when another explorer, Colonel John Blashford-Snell, saw a double-nosed dog in a remote village. The dog was named Bella and her owner reported that she was a member of an extremely rare breed found only in Bolivia.

The following year Blashford-Snell returned to the village. Unfortunately Bella had died in the meantime, but she had had a puppy, named Xingu, who also had a double nose. While Blashford-Snell was in the area with a team of scientists investigating a 30,000 year old meteor crater, Xingu had a litter of puppies with a single-nosed dog and two of the four puppies had double noses.

It’s possible that the Andean tiger hound is a rare dog breed still hanging on in remote areas of Bolivia, a descendant of Spanish dogs. Then again, it might just be a trait that crops up occasionally in the local dogs, either due to Spanish double-nosed dogs in the ancestry or a similar genetic anomaly that developed independently. The trait occurs in other breeds occasionally, especially in wolfhounds and bullmastiffs.

All the dogs we’ve talked about are good. They’re good dogs, Brad.

Next, Dan wanted to hear about the desert rain frog. I know we’ve talked about it before at some point, but only briefly and I can’t even find which episode. So all this information is new to me too.

The desert rain frog only grows about two and a half inches long, or 6 cm. It’s not your average hopping frog that sits on a lily pad and goes ribbit and maybe plays a tiny banjo. Instead, it’s a round boi with short little thin legs that it uses to dig burrows in the sand where it lives. Which is a desert. It’s a rain frog that lives in a desert. Also, it makes this sound:

[desert rain frog sound]

The desert in question is a 6-mile-wide strip of land, or 10 km, along the southwestern coast of Africa, right at the border of Namibia and South Africa. Yes, it’s a desert along the ocean. It’s actually a specific habitat called a coastal desert. The frog lives in a small part of the Namib coastal desert, which is probably the world’s oldest desert—possibly as much as 80 million years old. Parts of it have stupendously huge sand dunes, up to 980 feet tall, or 300 meters, and 20 miles long, or 32 km.

Because it’s an amphibian, the desert rain frog has to keep its skin moist. This can be difficult to do in a desert. It digs its burrow deep enough to find moist sand to rest on, and it absorbs the moisture through its skin. Coastal deserts also receive some moisture in the form of sea fog. This helps plants to grow on the dunes, which means animals like antelopes come to eat the plants, which is important because their dung attracts the insects the frogs eat.

The female desert rain frog lays her eggs in her burrow on damp sand. The eggs hatch into tiny froglets instead of tadpoles.

The frog’s legs are too short to allow it to hop, but it has webbed toes that help it walk on loose sand. It’s nocturnal and spends the day in its burrow, but at night it comes out to walk around and catch insects. It will also emerge during the day when there’s a lot of fog. It mostly eats beetles and moths that are attracted to animal dung and it probably also eats the eggs those insects lay in the dung and the larvae that hatch out of the eggs. Because its skin is moist, sand sticks to it and helps camouflage the frog while it’s aboveground.

I need to stress how round this frog is, because I don’t think I have made it clear. It’s very round, generally described as spherical. It’s a little bigger than a ping-pong ball but it resembles a ping-pong ball that’s stuck all over with sand and has round golden eyes and a frowny little mouth and absurdly short legs. It may actually be the cutest frog, and that is a ferociously competitive title.

Unfortunately, because the desert rain frog lives in such a small, specific habitat, it’s endangered due to habitat loss and pollution. Strip mining for diamonds is common in the area and people have also started building roads and grazing livestock along parts of the coastal desert. Hopefully the desert rain frog and its habitat can be protected before it’s too late.

Let’s listen to this little frog again. This is the sound a desert rain frog makes when it feels threatened, actually. There’s a link in the show notes to the iconic video taken by wildlife photographer Dean Boshoff, which is where I got the audio, and when you watch it you can see that the frog is actually backing away. It’s okay, little frog. Everyone loves you.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

Very recently, Page suggested the topic “animals discovered in 2020.” Since I was already thinking of doing something like this, I went ahead and bumped his suggestion to the top of the list and here we go!

You’d think that with so many people in the world, there wouldn’t be too many more new animals to discover, especially not big ones. But new scientific discoveries happen all the time! Many are for small organisms, of course, like frogs and insects, but there are still unknown large animals out there. In fact, 503 new animals were officially discovered in 2020. Every single one is so amazing that I had a hard time deciding which ones to highlight. In most cases we don’t know much about these new animals since studying an animal in the wild takes time, but finding the animal in the first place is a good start.

Many of the newly discovered species live in the ocean, especially the deep sea. In April of 2020, a deep-sea expedition off the coast of western Australia spotted several dozen animals new to science, including what may be the longest organism ever recorded. It’s a type of siphonophore, which isn’t precisely a single animal the way that, say, a blue whale is. It’s a colony of tiny animals, called zooids, all clones although they perform different functions so the whole colony can thrive. Some zooids help the colony swim, while others have tiny tentacles that grab prey, and others digest the food and disperse the nutrients to the zooids around it. Many siphonophores emit bioluminescent light to attract prey.

Some siphonophores are small but some can grow quite large. The Portuguese man o’ war, which looks like a floating jellyfish, and which we talked about way back in episode 16, is actually a type of siphonophore. Its stinging tentacles can be 100 feet long, or 30 m. Other siphonophores are long, transparent, gelatinous strings that float through the depths of the sea, snagging tiny animals with their tiny tentacles, and that’s the kind this newly discovered siphonophore is.

The new siphonophore was spotted at a depth of about 2,000 feet, or 625 meters, and was floating in a spiral shape. The scientists estimated that the spiral was about 49 feet in diameter, or 15 meters, and that the outer ring alone was probably 154 feet long, or 47 meters. The entire organism might have measured 390 feet long, or almost 119 meters. It’s been placed into the genus Apolemia although it hasn’t been formally described yet.

Another 2020 discovery off the coast of Australia was an entire coral reef a third of a mile tall, or 500 meters, and almost a mile across, or 1.5 km. It’s part of the Great Barrier Reef but isn’t near the other reefs. A scientific team mapping the seafloor in the area discovered the reef and undoubtedly did a lot of celebrating. I mean, it’s not every day that you find an entirely new coral reef. They were able to 3D map the reef for study and take video too. Best of all, it’s a healthy reef with lots of other animal life living around it.

Another big animal discovered in 2020 is one Patreon subscribers already know about, because we started out the year with an episode all about it. It’s a new whale! In 2018 scientists recording audio of animal life around Mexico’s San Benito Islands in the Pacific Ocean heard a whale call they didn’t recognize. They thought it probably belonged to a type of beaked whale, probably a little-known species called Perrin’s beaked whale.

In late 2020 a team went back to the area specifically to look for Perrin’s beaked whales. They did see three beaked whales and got audio, video, and photographs of them, but they weren’t Perrin’s beaked whales. The whale specialists on the expedition didn’t know what these whales were. They don’t match any species of known cetacean and appear to be a species new to science.

And speaking of new species of whale, guess what. Don’t say chicken butt. You can say whale butt, though, because the discovery of another new whale species was just announced. This one’s a 2021 discovery but there’s no way I was going to wait until next year to talk about it. It lives in the Gulf of Mexico and can grow over 41 feet long, or more than 12 meters. It’s a baleen whale, not a beaked whale, and it was hiding in plain sight. It looks a lot like the Bryde’s whale and was long thought to be a subspecies, but new genetic testing shows that it’s much different. It’s been named Rice’s whale, and unfortunately it’s extremely rare. There may only be around 100 individuals alive. It’s mostly threatened by pollution, especially oil spills like the 2010 Deepwater Horizon oil spill, and by collisions with ships. Hopefully now that scientists know more about it, it can be further protected.

Let’s move on from new gigantic animal discoveries to a much, much smaller one. A new pygmy seahorse was discovered off the coast of South Africa in May 2020. It’s brownish-yellow with pinkish and white markings and is only 20 mm long at most. A dive instructor who had seen the fish but didn’t know what it was told researchers about it and they organized a team to look for it. Its closest known relation lives in southeast Asia almost 5,000 miles away, or 8,000 km. Like other seahorses, it lives in shallow water and uses its flexible tail to hang onto underwater plants, but the area where it lives is full of huge waves rolling in from the ocean. It’s called the Sodwana Pygmy Seahorse after the bay where it was discovered, and officially named Hippocampus nalu. “Nalu” means “here it is” in the local Zulu and Xhosa languages, and it also happens to mean “surging surf” in Hawaiian, and it also happens to be the middle name of the dive instructor who spotted the fish, Savannah Nalu Olivier. Sometimes fate just says “this is the right name.”

A new species of pipefish, which is closely related to the seahorse, was also described in 2020, Stigmatopora harastii. It lives off the coast of New South Wales, Australia and can grow up to 5 ½ inches long, or 14 cm. It was first spotted by scuba divers in 2002. These divers know their fish. It lives among a type of red algae and is the same color red for camouflage. It’s surprising how long it took for scientists to discover it, because it’s not exactly hard to confuse with anything else. Except, you know, algae.

Not all newly discovered animals live in the ocean. In August of 2020 researchers discovered a new mouse lemur in Madagascar. We talked about a different type of mouse lemur in episode 135, that one discovered in 1992 and only growing to 3.6 inches long, or 9 cm, not counting its long tail. The newly discovered Jonah’s mouse lemur is only a little bigger than that. Mouse lemurs are the smallest members of the primate family. They’re also super cute but endangered due to habitat loss.

Another primate discovered in 2020 is one that researchers already knew about for more than a hundred years, but no one realized it was its own species, just like Rice’s whale. In 2020, genetic analysis finally determined that the Popa langur is a new species. It’s a beautiful fuzzy gray monkey with bright white markings around its eyes like spectacles. It lives on an extinct volcano in Myanmar and is critically endangered, with only an estimated 250 individuals left in the wild.

A 2020 expedition to the Bolivian Andes in South America led to the discovery of twenty new species of plant and animal, plus a few re-discoveries of animals that were thought to be extinct. The rediscoveries include a species of satyr butterfly not seen for 98 years, and a frog seen only once before, twenty years ago. The frog is called the devil-eyed frog because of its coloring. It’s purplish or brownish black with red eyes and only grows about an inch long, or 29 mm.

Another frog the team found is one of the smallest frogs in the world. It’s been identified as a frog in the genus Noblella and it only grows about ten mm long. As one article I read pointed out, that’s the size of an aspirin. It’s a mottled brown and black and it lives in tunnels it digs in the leaf litter and moss on the forest floor. It’s being referred to as the Lilliputian frog because of its small size.

In the summer of 2019, a team of scientists surveying the karst forests in northern Vietnam spotted an unusual snake. It was so unusual, in fact, that they knew it had to be new to science. It was dark in color but its small scales shone an iridescent purplish, and it was about 18 inches long, or almost 46 cm. It belongs to a genus referred to as odd-scaled snakes, and we don’t know much about them because they’re so hard to find. They mostly burrow underground or under leaf litter on the forest floor. The new species was described in late 2020.

A new species of giant scorpion was discovered in Sri Lanka in 2020. It lives in the forests of Yala National Park and is nocturnal. The female is jet black while the male has reddish-brown legs, and a big female can grow up to 4 inches long, or a little over 10 cm. It’s called the Yala giant scorpion after the park and is the sixth new scorpion species discovered in the park.

One thing I should mention is that all these scientific expeditions to various countries are almost always undertaken by both local scientists and experts from other places. Any finds are studied by the whole group, resulting papers are written with all members contributing, and any specimens collected will usually end up displayed or stored in a local museum or university. The local scientists get to collaborate with colleagues they might never have met before, while the visiting scientists get the opportunity to learn about local animals from the people who know them best, who also happen to know the best places to eat. Everybody wins!

Let’s finish with an astonishing fish that was technically discovered in 2018 and described in 2019, but was further studied in 2020 and found to be even more extraordinary than anyone had guessed. In 2018, after a bad flood, a man living in the village of Oorakam in Kerala, South India, spotted a fish in a rice paddy. He’d never seen a fish like it before and posted a picture of it on social media. A fish expert saw the picture, realized it was something new, and sent a team to Oorakam to retrieve it before it died or something ate it. It turned out to be a new type of snakehead fish.

There are lots of snakehead species that live in rivers and streams throughout parts of Africa and Asia. But this snakehead, which has been named the Gollum snakehead, lives underground. Specifically, it lives in an aquifer. An aquifer is a layer of water that occurs underground naturally. When rain soaks into the ground, some of it is absorbed by plant roots, some seeps out into streams, and some evaporates into the air; but some of it soaks deeper into the ground. It collects in gravel or sand or fractured rocks, or in porous rocks like sandstone. Sometimes an aquifer carves underground streams through rock, creating caves that no human has ever seen or could ever see, since there’s no entrance to the surface large enough for a person to get through. In this case, the heavy rain and floods in Oorakam had washed the fish out of the aquifer and into the rice paddy.

The Gollum snakehead resembles an eel in shape and grows abound four inches long, or 10 cm. Unlike fish adapted for life in caves, though, it has both eyes and pigment, and is a pale reddish-brown in color. This may indicate that it doesn’t necessarily spend all of its life underground. Aquifers frequently connect to springs, streams, and other aboveground waterways, so the Gollum snakehead may spend part of its life aboveground and part below ground.

When it was first described, the researchers placed the fish in its own genus, but further study in 2020 has revealed that the fish is so different from other snakeheads that it doesn’t just need its own genus, it needs its own family. Members of the newly created family are referred to as dragonfish.

Other snakeheads can breathe air with a structure known as a suprabranchial organ, which acts sort of like a lung, located in the head above the gills. Not only does the Gollum snakehead not have this organ, there’s no sign that it ever had the organ. That suggests that other snakeheads developed the organ later and that the Gollum snakehead is a more basal species. It also has a small swim bladder compared to other snakeheads.

Researchers think that the dragonfish family may have separated from other snakehead species as much as 130 million years ago, before the supercontinent of Gondwana began breaking up into smaller landmasses. One of the chunks that separated from Gondwana probably contained the ancestor of the Gollum snakehead, and that chunk eventually collided very slowly with Asia and became what we now call India.

The Gollum snakehead isn’t the only thing that lives in the aquifer, of course. Lots of other species do too, but it’s almost impossible to study them because they live underground with only tiny openings to the surface. The only time we can study the animals that live there is when they’re washed out of the aquifers by heavy rain. It turns out, in fact, that there’s a second species of dragonfish in the aquifer, closely related to the Gollum snakehead, with a single specimen found after rain.

So, next time you’re outside, think about what might be under the ground you’re walking on. You might be walking above an aquifer with strange unknown animals swimming around in it, animals which may never be seen by humans.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

It’s the very last week of 2020, and good riddance. Let’s kick the old year out the back door and welcome in the new year with a basket of pretty frogs. That’s right, we’ve got a frog episode this week!

Let’s start with the northern leopard frog, with thanks to an anonymous reviewer who gave the podcast a really nice five-star review and only signed the review “norhern lepord frong.” I looked that frog up online to see what it looked like, and it’s so pretty, honestly, it’s just the prettiest frog! If you had a basket of northern leopard frogs, they might just look like friendly flowers, because while most are green or brown with darker spots, some are much brighter green with yellow markings, some are dark brown, and some are even pinkish white because of a rare albino trait. Its spots are outlined with yellow or light green and it has two folds of skin that run the length of the body and are sometimes yellow. These folds of skin are called dorsolateral folds and many frogs have them, although they’re not always as easy to spot as in the northern leopard frog.

The northern leopard frog is native to the northern part of North America, especially southern Canada and the northern and western United States. It grows up to 4.5 inches long, or 11.5 cm, measured from snout to vent. As you may recall from previous frog episodes, that’s how frogs are always measured. It basically just means nose to butt. Females are larger than males, which is also the case for most frogs.

It lives anywhere that it can find fresh water, including rivers, streams, creeks, ponds, marshes, even drainage ditches, but it prefers slow-moving or quiet water. As a result, it’s threatened by loss of habitat, pollution, and climate change, all of which affect the water it needs to live, and it’s also threatened by non-native animals and diseases. But while it doesn’t live in as many places as it used to, right now it’s doing fine overall and isn’t considered endangered.

Like most frogs, the northern leopard frog eats insects and any other small animal it can swallow. It has a long sticky tongue that it can shoot out so quickly that even an insect can’t outfly it, but it doesn’t just eat insects. It’s a big frog with a big mouth, and it’s been recorded eating other species of frog, small snakes, small birds, and even a bat. But mostly it eats insects, slugs, snails, and worms. Probably the frog that was documented as catching and eating a bat is famous in the northern leopard frog world, or at least it would be if real life was like the inside of my head and frogs had their own tiny newspapers.

The northern leopard frog was once considered a delicacy, with most frogs’ legs coming from this particular species. It’s also sometimes kept as a pet. It’s mostly nocturnal and semi-aquatic, sometimes called the meadow frog because it will leave the water to hunt for food in grassy areas. It hibernates in winter but is better adapted to cold weather than a lot of frogs are.

There’s also a southern leopard frog that looks very similar to the northern leopard frog but lives farther south, which you probably guessed from the name. It’s also slightly larger than the northern leopard frog, up to five inches long, or 13 cm.

Male leopard frogs, like many other frogs, have special vocal sacs in the throat that allow a male to make a loud call in spring to attract females. Different species of frog have different calls, naturally, and the vocal sacs are shaped differently in every species. The male leopard frog, northern and southern, has two vocal sacs that he fills with air like balloons, which amplifies the sound of his voice and makes it much louder.

This is what a northern leopard frog sounds like:

[frog sound]

Another colorful frog is from India and was only discovered in 2010. A team of scientists surveying the mountains for reptiles and amphibians noticed a teensy frog in the leaf litter one night. Its back was brown with light blue dots that looked like stars in a night sky, but its belly was orange like a sunset. It’s a very pretty frog.

The researchers caught several of the frogs and thought they were pretty but not especially unusual. There are at least 400 known frogs in India and new species are found pretty frequently. The team named it the starry dwarf frog because of the blue dots and its size, less than 20 mm long, or around half an inch. That’s about the size of an adult’s thumbnail.

After the expedition, though, when the team examined the frogs more closely, they realized they had something different from other frogs. It didn’t seem to be related to any other frog species in India or anywhere else. A genetic analysis indicated that the starry dwarf frog is literally not closely related to any frog alive today. For millions of years India was a big island after it separated from Madagascar and Africa but before it collided with mainland Asia, so many species evolved independently from species in other parts of the world. Scientists hope to learn more about the starry dwarf frog to learn more about how other frogs evolved.

Let’s move on to another colorful frog, and a very weird one, the turtle frog. Simon brought this one to my attention, so thank you, Simon! This frog gets its name because it sort of looks like a tiny turtle without a shell.

The turtle frog lives in western Australia in areas that are much dryer than most frog habitats. Its body is bulbous with strong, stubby legs that allow it to burrow into the sand. Generally, when a frog burrows into sand or mud it does so by moving backwards, digging itself deeper with its strong hind legs. But the turtle frog digs forward, using its front legs to dig. Turtles are also forward diggers. Unlike most other frogs, the turtle frog doesn’t have long hind legs that it uses for jumping. It just has short legs in front and back.

It ranges in color from brown to reddish-brown to pink and it grows up to 2 inches long, or 5 cm. Its head is small, rounded, and distinct from the body, like a baby turtle’s head sticking out from its shell–but without a shell, without a beak, and with small black-dot eyes.

Obviously the turtle frog isn’t related to the turtle at all. Turtles are reptiles while frogs are amphibians. The turtle frog has adapted to a semi-arid climate and a diet of termites by evolving the ability to dig deep burrows, some of them almost four feet deep, or 1.2 meters, and the ability to break into termite nests. As a result, its body plan is different from most other frogs.

That’s not all that’s different, though. Most frogs lay eggs in water, which hatch into tadpoles that live in the water until they metamorphose into small frogs. The turtle frog doesn’t have that kind of luxury. It doesn’t have a lot of water most of the time, so it hatches into a tiny froglet instead of a tadpole.

The most colorful frogs in the world live in the tropics, especially the poison dart frogs of Central and South America. Poison dart frogs are diurnal, meaning they’re most active during the daytime, and they’re fairly small, with the biggest species growing to no more than about two and a half inches long, or 6 cm. Different species of poison dart frogs are different colors and patterns, ranging from a lovely bright blue to red or yellow. These little frogs need to be brightly colored so that predators know to leave them alone, and the reason they should leave them alone is that poison dart frogs are incredibly toxic.

You may have heard the story that natives of South America would rub the tips of their darts or arrows on these frogs to transfer the frogs’ toxic secretions to the weapons. That’s where the name poison dart frog comes from. That’s sort of true, but not completely true. Not all poison dart frogs were used in this way, just four of the largest species that are especially toxic.

One of these four species is the golden poison dart frog, which lives in the rainforests of Colombia. It’s usually bright yellow with black eyes, although some individuals are a minty green or orange. It looks cheery, but a single frog has enough poison to kill two African elephants, not that it would because it lives in South America and not Africa and the elephants would not try to eat the frog. One frog has enough poison to kill 10 to 20 humans, though, so don’t try to eat one. In fact, don’t even touch it, because poison dart frogs store their poison in skin glands and if a frog feels threatened, it will secrete a tiny amount of the poison. If that poison gets into your body, you will die.

So why do people keep golden poison dart frogs as pets? That would be like having a pet stick of dynamite, right? Actually, it turns out that frogs born in captivity don’t develop the toxins that wild frogs have. Frogs that are captured in the wild and kept in captivity will eventually lose the toxins, although it may take several years. This is because the frog doesn’t manufacture the toxins itself but retains toxins found in some insects it eats, although researchers aren’t sure yet which insect or insects.

The golden poison dart frog lays its eggs on the ground. This sounds weird until you remember that it lives in a rainforest and the ground is covered with dead leaves that are constantly wet from rain. When the eggs hatch into tadpoles, though, they need more than just wet leaves, so the parent frogs squat down and the tadpoles wriggle onto the parents’ backs. They stick there and the parents carry them not to a pond but up into the trees. Water collects in the middle of large leaves of some rainforest tree species, and of course there are always little hollows and holes in tree trunks that can fill with rainwater. The frogs deposit the tadpoles into these little puddles, where the tadpoles eat mosquito larvae and algae. But even then, the parents don’t abandon their babies. Golden poison dart frogs are social animals, not generally a trait you associate with frogs, and they live in little groups of around half a dozen individuals. When the tadpoles finish developing and metamorphose into adult frogs, the parents lead their babies to other golden poison dart frogs so they can join a group.

Finally, our last colorful frog of the episode and the very last animal we’ll cover for 2020 is the tomato frog. As you might have guessed, the tomato frog is red-orange in color. It lives in Madagascar and a big female can grow up to 4 inches long, or 10.5 cm. Males are much smaller and are more yellow than red. But the tomato frog doesn’t use its coloring to hide among tomato plants. Its coloring advertises that it’s toxic, although its toxin is much different from those found in poison dart frogs and not deadly.

The tomato frog mostly eats worms and termites, which it finds by digging around in the leaf litter. It also catches insects with its sticky tongue. It’s not a very good swimmer, surprisingly, and spends most of its time on land or in swampy areas. It’s a mostly nocturnal frog.

If a tomato frog feels threatened, it will puff itself up to appear larger, which also incidentally makes it look even more like a tomato. It will also secrete a sticky white toxin that irritates a predator’s mucus membranes and can cause serious allergic reactions in humans. The toxin is so sticky that it will remain in the predator’s mouth for days. So if you live in Madagascar and have a tomato garden, carefully examine every tomato before you take a bite.

This is what a tomato frog sounds like:
