Other Crustaceans

There are many other crustaceans besides crabs. Barnacles are small, round animals that look like rocks. They live in large groups.

Shrimp are also crustaceans. They are longer than crabs and don't have claws. They live in reefs too.

Lobsters and prawns are crustaceans too. There are 30,000 types of crustacean in the oceans!
