Abstract
Nine stages and substages of post-, inter- and premoult were distinguished in the West Coast rock lobster Jasus lalandii by microscopic examination of the cuticle, epidermal retraction and setal development in the pleopods. The postmoult condition is characterized by progressive thickening of the setal walls and cuticle through to inter- moult. Premoult commences with apolysis (Stage Do), followed by setal development (Stage 01', 0(, 0,"') and culminates with cuticle deposition (Stage O2), The diagnostic features of the stages are generally similar to those of other decapod crustaceans.
