Octopus & cuttlefish
Gloomy octopus, Maori octopus, blue-ringed octopus, pyjama squid and cuttlefish, the stars of every temperate night dive.
Octopus tetricus, O. maorum, Sepia spp.
Southern Australian night dives are about cephalopods. The gloomy octopus (Sydney's common octopus, which builds midden-ringed dens in the sand at Cabbage Tree Bay and Jervis Bay), the huge Maori octopus of Victoria and Tasmania, the southern blue-ringed octopus under every rock (deadly, never handled), the striped pyjama squid and the southern dumpling squid burrowed in the sand under piers, and cuttlefish of several species hovering in the torch beam. The piers of the Mornington Peninsula and the Yorke Peninsula and the harbour sites of Sydney are the reliable venues.
