"Exoskeleton, in contrast of endoskeleton, is a general term to describe various external anatomical features that support and protect animals' bodies. Many invertebrate animals such as insects, crustaceans and shellfish have exoskeletons. Without scales, shell or a thick fur coat, human invented armour which resembels endoskeleton in its protective function."
