Some advantages of an exoskeleton. Introduction: Exoskeleton is a hard layer of protective material, around the outer epithelial covering of some animals. It may exist as a shell in some animals such as crabs and crustaceans. Exoskeletons are made of chitin or calcium carbonates which are very strong and hard materials that give strength to organisms and protect them from the environment. Animals having exoskeletons often do not have a backbone.
