Durable shell protects cancer from the enemies, but interfere with his development, constraining its growth, so cancer from time to time it dumps its solid covers, or as they say, sheds. Young crabs molt more often than adults. During molting crayfish can break off the claws, legs and antennae, but they grow back again.
