Carapace

Carapace (/kærəˌpeɪs/) is a term used in zoology to describe a protective, shell-like covering, or shield, that covers the dorsal (back) part of an animal.

Etymology

The term 'carapace' is derived from the French word 'carapace', which itself is from the Spanish 'carapacho'. The Spanish term is of uncertain origin, but it may be a compound of 'cara' (face) and 'pacho' (cloak).

Definition

A carapace is a hard, protective covering that is found in many animals, including turtles, crabs, and scorpions. It serves to protect the animal's internal organs and provides a form of defense against predators. The carapace is typically composed of chitin, a strong and flexible material, or calcium carbonate, which provides additional strength and rigidity.
