Have you ever seen a crab when you were at the beach? Well that means you have seen a crustacean! Crustaceans are crabs, lobsters, shrimp, sand hoppers, barnacles, crayfish and slaters.
Crustaceans are usually found in the ocean but some crustaceans live on land as well. The only crustaceans living on land is the slater, also known as a woodlouse.
All water crustaceans have a exoskeleton made of calcium. Their body is made up of an antenna, eyes, thorax, crusher claw, walking legs, head, swimmerets, flippers, tail and abdomen.
Crustaceans eat scraps and dead creatures, but slaters eat rotten wood.
My favourite crustaceans are hermit crabs because I think they are cute. Here is a diagram of one.
We need to look after crustaceans because they are a great food resources and they clean up our oceans. You can help by not using plastic and picking it up.
