Available wild-caught, these marine dwelling cephalopods are found right around the Australian coast, from shallow tidal pools to depths of over 3,000m, though generally caught closer inshore among seagrass and on muddy, sandy or reefy bottoms at less than 200m on the continental shelf.
They are mostly solitary, living in holes, under rocks or burrowing into the sea bottom. Mainly caught off south-eastern Australia, from southern Queensland to the Great Australian Bight, often as bycatch, using trawls, dredges, pots and nets; one species is trapped and taken as bycatch of the WA Rock Lobster fishery (as they are a major predator of Rock Lobsters).
