The blue-ringed octopuses (genus Hapalochlaena) are three (or perhaps four) octopus species that live in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia. Their primary habitat is around southern New South Wales, South Australia, and northern Western Australia.
Octopuses such as the Greater blue-ringed are part of the Cephalopoda class, which is the same taxonomic group where squid and cuttlefish can be found. Hapalochlaena lunulata was first discovered and described in 1832 by Quoy and Gaimard, two French naturalists.
