exoskeleton - Skeleton covering the outside of the body, or situated in the skin. In Arthropoda the exoskeleton, e.g. cuticle of insects, or lime-impregnated cuticle of crabs, is superficial to the epidermis. Shell of many molluscs is a similar exoskeleton of lime-impregnated cuticle. In many vertebrates, e.g. scaly fish, tortoises, armadillo, the exoskeleton consists chiefly of bony plates beneath epidermis; in tortoise and armadillo these plates have a horny covering of keratin derived from epidermis. Compare with: Endoskeleton.
