Greater blue-ringed octopus
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

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

Nsɛm
The greater blue-ringed octopus is one of the most venomous marine animals in the world, despite being small.1
Its venom contains tetrodotoxin, the same toxin found in pufferfish.1
There is no known antidote or antitoxin for tetrodotoxin, and the toxin does not break down when heated or boiled.1
Its blue rings are a warning signal to predators, showing that it is highly venomous.1
Males die after mating, and females die after guarding their eggs because they refuse to eat.1
