The<unk><unk><unk> es (genus Hapalochlaena) are three (or perhaps four)<unk>  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. They are recognized as one of the world's most venomous marine animals. Despite their small size and relatively docile nature, they are dangerous to humans if provoked and handled, because their venom is powerful enough to kill humans.
They can be identified by their characteristic<unk>  and black rings, and yellowish skin. When the<unk>  is agitated, the brown patches darken dramatically, iridescent<unk>  rings, or clumps of rings, appear and pulsate within the maculae. Typically, 50–60<unk>  rings cover the dorsal and lateral surfaces of the mantle.
They hunt small crabs, hermit crabs, and shrimp.
