Sharks

What has fins, sharp teeth, and swims in the ocean? A shark!

Sharks have been around for a very long time. Sharks have lived in the oceans even before dinosaurs roamed the earth! Sharks are fish, and there are over 400 types of sharks. When they have babies, the babies are called pups.

Sharks lose their teeth, like humans, but they don't just lose their baby teeth. They lose teeth throughout their lives. When a shark loses a tooth, a tooth from another row of teeth will move into its place. New teeth are always growing. Most sharks are carnivores, so they feed on other animals, like fish or seals.
