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

This week is our Halloween episode, and a brand new one since I wasn’t going to skip Halloween! I thought about covering a really spooky topic, but decided to go with interesting instead. Thanks to Murray and Nathan Andrew for their suggestions this week.

First, though, a quick note that if you check the show notes, or go to the website at strangeanimalspodcast.blubrry.net, you’ll find a link to buy the Small Mysteries ebook! Unless I forgot to add it! It’s $3 and is available in epub, PDF, or whatever format file it is that Kindle uses. The ebook of Beyond Bigfoot & Nessie is there too for $5, which is cheaper than anywhere else.

We’ll start with Murray’s suggestion, the Indo-Pacific leopard shark! You might find this animal spooky if you’re afraid of sharks, but Murray isn’t, and in fact he was snorkeling off the coast of Australia where he lives when he saw a leopard shark not too long ago!

The Indo-Pacific leopard shark is also called the zebra shark, and it’s a different animal from the leopard shark that lives off the Pacific coast of North America. It’s bigger, for one thing. It can grow over 8 feet long, or 2.5 meters, and possibly larger. It’s covered with small dark brown spots on a lighter brown or yellowish background.

The reason it’s also called the zebra shark is because baby leopard sharks have stripes. The young shark is dark brown with a yellowish belly, and it has white or pale yellow stripes and spots. It looks so different from the adult leopard shark that scientists in the 18th century thought they were separate species.

The leopard shark lives in shallow water, often around coral reefs. It’s most active at night, and spends the day resting on the bottom of the ocean, doing nothing much. Murray pointed out that the leopard shark is the only shark that doesn’t have to keep swimming in order to push water through its gills, and I had to look this up to see if it was true. It turns out that a few sharks, including the leopard shark, have special organs called spiracles that pull water into the respiratory system without the shark needing to move. The spiracles are small openings just behind the eyes. It allows some bottom-dwelling sharks to rest on the sea floor. All other sharks really do have to keep swimming or they’ll suffocate. The leopard shark usually rests with its head pointing into a current, which helps bring oxygenated water to it so its spiracles are more effective.

The leopard shark mostly eats mollusks, along with small fish, crustaceans, and other small animals. It’s a slender, slow-moving shark that lives throughout the tropical Indo-Pacific. Its eyes are very small and so is its mouth, and it almost never bothers people. In other words, it’s not very spooky but it is very
