The greater blue-ringed octopus is a small sea creature that lives in the warm shallow waters of the Indo-West Pacific, including around Australia. It is one of the most venomous marine animals in the world, so knowing what it looks like matters.1

It lives in shallow water over mixed seabeds such as rubble, reefs and sand. It hides in a burrow and comes out only to find food or a mate. The entrance to its burrow is littered with leftover crab and shell remains, which makes it easy to spot.1

It eats small crabs, shrimp and molluscs, and sometimes small injured fish. It pounces on prey, seizes it with its arms and pulls it to its beak, which pierces the shell or exoskeleton and releases venom.1

Its venom contains tetrodotoxin (TTX), a powerful neurotoxin, which is a poison that attacks the nerves. It paralyses the muscles needed for movement, and in people it can lead to death through respiratory paralysis, which means the breathing muscles stop working. Symptoms include tingling and numbness of the face and lips, sweating, severe headaches, dizziness, speech problems, weakness and vomiting. Symptoms can appear between 15 minutes and four hours after a bite, and the victim stays conscious throughout.1

The bite is capable of being fatal to humans. The bite is painless, so a person may not notice it. Children are more sensitive to the toxin. Death can occur between 20 minutes and 24 hours after symptoms begin.1

It flashes its blue rings as a warning to predators, and it uses its venom to defend itself.1
