starts withThe species has five pairs of legs that are used to move across the ocean floor, with the fifth set possessing claws in the females, and six smaller pairs are located at the mouth. The eyes are located at the ends of the stalks. They vary in colour from a brownish purple to a pale colour. The exoskeleton is segmented, and must be shed as the animal grows. The largest recorded specimen is 5.5 kilograms (12 lb), but a maximum weight of 5 kg (11 lb) is considered typical. The average accepted form of measurement, that of the carapace, is from 80 to 100 millimetres (3.1 to 3.9 in) in length.
The range of the species is along the coast of Western Australia, from Hamelin Bay to the North West Cape, and at islands such as the Houtman Abrolhos. The larvae of the species develop in the meadows of seagrasses of Western Australia, migrating out from these toward the deeper ocean and coral reefs such as the Abrolhos Islands.
