The "shell" of the crayfish, or rather its exoskeleton, is composed of the polysaccharide chitin and some lipids. There are also some calcium salts in the exoskeleton of the crayfish, which gives it its firmness.

Why do crayfish shed their skin?
Crayfish shed their shells because they are growing. they do not shed their skin, but rather the inflexible shell on top. Because it is inflexible, it cannot grow with the crayfish and they have to make new ones. Replacing a shell is called "molting". crayfish and other crustaceans molt more when they are young and are growing faster. Hope this helps!
