A carapace is typically found in animals such as turtles, crabs, and other members of the class Reptilia and various crustaceans. It is a hard, protective shell that covers the dorsal side of these creatures and provides both structural support and defense against predators. In turtles, the carapace is composed of bony plates covered by scutes, while in crabs and other crustaceans, it is often made of a chitinous material. The carapace not only offers physical protection but also plays a role in regulating body temperature and preventing desiccation in certain environments.
