Pufferfish, puffed: Dog nose: Show transcript: Welcome to the bonus Q&A episode of Strange Animals Podcast! I’m your host, Kate Shaw, and this is a little extra episode where I answer listener questions. So let’s jump right into it. To start us off, Simon and Thia wanted to know how I first became interested in animals. I really don’t know! When I was little, I didn’t want to play with dolls, I wanted to play with my stuffed animals. I actually have a toy cat named Whiskers who I’ve had since I was four. Whiskers is older than all my teeth! I especially loved horses as a kid and since my family couldn’t afford to buy me a horse, I took riding lessons and read everything I could find about horses, fiction and nonfiction. All that reading about horses led to reading about other animals, and the more I read, the more interested I became in animals of all kinds. Next, Melissa of the awesome podcast Bewilderbeasts asked, “What was the fact or episode that really slapped you out of left field, like, ‘I didn’t see that coming AT ALL’?” OH MY GOSH, how many times has that happened to me? The most astounding fact I can think of isn’t actually about an animal at all but about trees. While I was researching the Temnospondyl episode, which had a related Patreon episode that ran at about the same time, I came across the fact that when trees first developed, nothing could break down the tough compound called lignin that hardens a tree’s cells to make wood and bark. When a tree died, its trunk just stayed where it fell forever, and this happened for at least 50 million years and possibly 100 million years. 100 million years of tree trunks just lying all over the ground! You wouldn’t be able to walk anywhere! You’d have to climb over hundreds of millions of fallen tree trunks, although naturally as the years passed the older ones would get buried deeper and deeper in the earth. But there would always be more! This blew my mind, and later I came back to it, determined to do more research and make sure it was accurate. I did a whole lot of research, because it just didn’t seem possible, and that information ended up in episode 214. As for an animal that blew my mind, I still have trouble believing ice worms are real. They’re worms that live in snow and ice! We covered them last August in episode 185 and I’m still reeling. Next, Llewelly asks what my favorite extinct animal is, or animals. Why would you make me choose? This is so hard. Okay, fine, I’ll narrow it down to hoofed Pleistocene megafauna like the giant deer and elasmotherium and so many other animals with weird horns and ossicones and things like that. What really gets me is that they lived so recently! Many of them only died out 11,000 years ago, and some were probably around much more recently in a few isolated areas. It also really reminds me to appreciate the megafauna that’s still around. We live at the same time as giraffes! Next, Richard E. asked, “Does your job involve the study of animals and/or is the pod something that you really wanted to do?” Tracie also asked what my background is, if I’m a professor or zookeeper or something similar. Helenka also asked my background and how I got interested in strange animals. I’m kind of embarrassed that I never have pointed out that I’m not an animal expert, to steal a phrase from the awesome podcast Varmints! I actually work as a test proctor, AKA invigilator, in a large community college, so my work doesn’t have anything to do with animals. My background is in elementary education although I didn’t teach long. Basically I got my K-8 teaching certification and M.Ed., did some substitute teaching afterwards, and ended up getting my current job instead of taking a teaching position. I still love teaching, so when I decided I wanted to start a podcast, I knew it would be nonfiction. My undergraduate degree is in English literature, and I took so many history courses that I minored in history almost by accident, so I’m really good at research and can write an essay about any topic in the world in very little time. I didn’t know it when I was in college, which was long before podcasts existed anyway, but I have the perfect background for creating a nonfiction podcast. Liesbet has three questions about the podcast: what inspired me to start it, what motivates me to keep going without missing any episodes, and what I enjoy most about it. I’m so pleased that someone noticed I’ve never missed a single episode! Not that it would be the end of the world if I did, of course, but if I did, I’d feel bad thinking about people who were looking forward to listening to the new episode and were disappointed when there wasn’t one. Here is the raw, honest truth about why I started Strange Animals Podcast. It was several things combined and the whole story is kind of dumb. First, my friend Kevin makes a great pop culture podcast called The Flopcast, and after I’d listened to it for a while I thought, “Hey, that sounds like fun. I think I’ll start a podcast.” About the same time, I was listening to a back episode of a podcast I will not name, and it gave some misinformation about the Irish elk, specifically the outdated theory that it went extinct because its antlers were too big. I mentioned that in episode 4 and how I kept thinking about it and got kind of angry that a large, influential podcast hadn’t bothered to do enough research about an animal that lots of people are interested in. I decided I could do better and that my podcast would be about animals. Also at the same time, I was trying to find a good podcast about mystery animals that was well researched and didn’t skate off into speculation too much. I couldn’t find one that satisfied me, so I had to make one myself. I wasn’t exactly sure what my focus would be when I first started the podcast. You can kind of tell when you listen to the first six months or so of the podcast that I was trying out new things and figuring out what worked best and what I liked best. I’m still figuring that out, for that matter. It’s hard to decide what I like best about making the podcast. I like the whole process, except maybe not the frustrating parts of recording and editing. I think my favorite part has to be when I uncover information I find really exciting. I get to share that information with everyone who listens! It’s fantastic! Next, let’s get into some questions about animals. Pranav asked if I would explain how poisons work, which is a great question and also just a tiny bit alarming. No one eat anything Pranav cooks for you unless he’s eating some too. Actually, of course, he’s just wanting to learn more about poisonous animals, and I’ll talk about venomous animals too. A poisonous animal contains toxins somewhere in its body, like the hooded pitohui bird that we talked about in episode 222 that has poisonous feathers. The poison stops other animals from trying to eat it. In the case of the hooded pitohui, its poison causes your skin to burn when you touch it, so an animal that tries to bite it will have a burning mouth. If it actually eats any of the poison, the animal can die. Many amphibians secrete toxins through their skin, like the poison dart frog, and many other animals concentrate toxins in their muscles or internal organs. A venomous animal has toxins that it can inject into a wound to hurt or kill another animal. Some snakes can inject venom with special fangs, but some amphibians have pointed ribs that are sharp enough to stab a potential predator. The ribs will project through the amphibian’s sides through tiny spots that are filled with toxins. The toxins coat the points of the ribs, and if the predator tries to bite down, it gets those toxins stabbed right into its mouth. Some fish have spines that are coated in toxins, and of course many insects, arachnids, and other invertebrates have stingers that inject toxins. Generally, a poisonous animal absorbs toxins from a food it eats, often a toxic insect, and instead of getting sick, it uses those toxins to protect it from predators. A venomous animal usually produces its own toxins in its body, especially animals that use venom to kill or disable prey. It costs energy for the animal to make venom, and it doesn’t want to waste it. That’s why snakes will sometimes give what are called dry bites in self-defense, where it bites but doesn’t inject any venom. It’s hoping that the pain of the bite itself will make a potential predator retreat without the snake needing to use venom. Different toxins have different effects, naturally, and animals produce so many different kinds of toxins that we could talk about it all day and not even cover them all. Instead, let’s quickly discuss two animals, one venomous and one poisonous. Our venomous example is the king cobra. It can grow over 18 feet long, or 5.5 meters, and lives in southern Asia. It mostly eats other snakes and some lizards. Its venom contains numerous toxins that do different horrible things. The neurotoxins in its venom affect the central nervous system, which can cause all sorts of issues like dizziness, pain, blurred vision, sleepiness, and even paralysis. Other toxins in the venom are called cardiotoxic because they affect the heart, making it weak so that circulation of blood slows down. If a king cobra bites you and injects venom, you can die within 30 minutes as the venom basically just shuts your body down, one process at a time. If your heart stops or your diaphragm becomes paralyzed so you can’t breathe, that’s it for you. Fortunately, in ordinary situations the king cobra is shy and avoids people,...
