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