Sharks

Sharks are one kind of fish. They live deep in the ocean where it is very cold. Sharks can be very large.

They do not have bones. They have cartilage. It is the same thing you have in your nose and ears. They have tiny slits in the side of their heads. These slits help them to breathe air. Their teeth are very sharp. Extra teeth are hidden inside. Sometimes they lose one tooth, and a new one will grow right back in. Some huge sharks can grow teeth that are as big as a hand.

Sharks like to eat meat, fish, and plants. Some sharks swim with their mouths open to catch plants. The plants stick to the sides of their mouths. Others eat seals or small animals in the ocean.

If you want to see a shark, the best and safest place is at the aquarium!
