What animal uses an armor plate?
Many animals have armour-plated skins. The most common and popularly known is the Armadillo, but there is also the lesser-known Pangolin with its thick hide of interlocking armour plates. One should also not overlook the exoskeletons of insects, arachnids and crustacea such as crabs, sea urchins and lobsters either, all of which are armoured in their own way. Shellfish also employ a form of armour plating to protect their vulnerable bodies, as do snails and turtles.
