The industry came to be centred at the Houtman Abrolhos, at the edge of the continental shelf, where the mature crays occur in large populations. A cannery was established at the islands to export the seasonal catch in the 1930s. The early industry claimed to harvest up to fourteen species, however, research into the Abrolhos populations recognised only three.

The recognition of the species was relevant to the conservation of its related fishing industry, it is unique to the region and could not be naturally repopulated from other regions.

The 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
