Carapace

Definition: The carapace is the hard outer shell or exoskeleton of crustaceans, such as shrimp and crabs.

Function in the Aquarium: The carapace serves as a protective outer covering for the body of crustaceans. It provides structural support and protects the internal organs. In shrimp, the carapace is periodically shed through the molting process, allowing the shrimp to grow. Observing the condition of the carapace is essential for assessing the health and growth of crustaceans in the aquarium.
