All about Crabs
Crabs are crustaceans with a hard outer shell called an exoskeleton. They have ten legs, and the front pair often has large claws.
Crabs grow by shedding their shell in a process called moulting.
Crabs walk sideways more often than forwards, and they live in the sea, rivers and on land.
During this time they are soft and vulnerable, so they hide until the new shell hardens. Crabs eat plants, dead animals and small creatures.
