What has fins, sharp teeth, and swims in the ocean? A shark! Sharks have been around for a very long time. Sharks live in the oceans. 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. They lose teeth throughout their lives, so new teeth are always growing. Most sharks feed on other animals, like fish or seals. Sharks might look scary, but they are not dangerous to people. To be safe, though, it is a good idea to leave sharks alone if you see them!
