Most abundant in sheltered marine embayments and estuaries (Ref. 122767). Estuarine, inshore, intertidal to subtidal (Ref. 106854). Occurs in coastal waters (Ref. 122766). Lives in a variety of inshore and continental shelf waters. Prefers flatter sandy
to muddy bottoms with algal and seagrass communities (Ref. 111207).
Fertilized eggs appear 6 months after mating, females carry the eggs onto the pleopods until they hatch. Planktonic eggs hatch after ~15 days (24°C) and the larval stage consists of 4 zoeal and 1 megalopae stages. Growth is rapid, juveniles of 6 months age caught in fishery. Females undergo pubertal moulting at 6-10 months of age, males a few weeks before. Sexual dimorphism observed, males are blue in color while females are olive green or brown (Ref. 128184).
