Exoskeleton

Definition: The exoskeleton is the external skeleton or hard outer covering of invertebrates such as shrimp, providing support and protection. It must be shed for growth to occur.

Function in the Aquarium: Invertebrates, such as shrimp and crabs, periodically shed their exoskeletons through a process called molting. Molting is crucial for growth and repair. Maintaining appropriate water parameters is extremely important to enable the molting process to occur. A failed molts usually results in the death of the animal.
