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.
Marine biologist Anthony Chang observes this blue-ringed octopus in Singapore. This octopus, native to Australia and other islands in the Pacific Ocean, is one of the most venomous marine creatures in the world. Blue rings appear in the octopus when it is irritated or excited, so beware!
