Some animals do not keep their hard parts inside the body, the way we keep bones. Insects, spiders, crabs, and lobsters grow a hard shell on the outside instead. That outer shell is an exoskeleton. It holds the body up, keeps it safe, and gives muscles something to pull against. When the animal gets too big for the old shell, it has to climb out and wait for a new one to harden — that is why empty crab shells turn up on the beach. The word is a bit scientific; you meet it in nature class first. Though actually, people also use it for a machine you wear, a robot frame that helps a person stand or lift heavy things. That later meaning is the same picture, just built of metal instead of shell.
組成From exo- ('outside') + skeleton. The exo- goes back to Ancient Greek ἔξω (éxō), 'outside'.
