Answer to Question #219551 in Zoology for Kamogelo

Question

Give an account of ecdysis in crustaceans and refers specifically to the role of external stimuli and hormones

Answer 1

Ecdysis is the process of an arthropod moulting its exoskeleton. Moulting is necessary as the arthropod exoskeleton is inflexible and so, to grow larger, arthropods must moult. Once the new exoskeleton has dried and hardened the animal can move again.
