Catshark Introduction

There are many different species of catshark, but most of them are small, harmless fish. They live in temperate and tropical oceans throughout the world. Some species migrate, while others tend to stay in one area. Some catsharks live in shallow waters; others live in water up to 6,600 feet beneath the ocean’s surface.

Most catsharks are oviparous, meaning they lay eggs rather than giving birth to live young. They lay their eggs in a tough, leathery pouch called a “mermaid’s purse,” and leave the purse on the seabed. After almost a year, a young shark hatches from the egg.

Catsharks eat bony fish, squid, and octopus. They have 40 to 110 rows of teeth—sort of like a hedgehog’s quills—and their teeth fall out and are replaced every 18 to 31 days!
