The greater blue-ringed octopus reaches just 12 cm in length. It looks similar to the blue-ringed octopus but the blue patterns on its body are all rings. The blue rings do not stand out when it is relaxed. Similar to the blue-ringed octopus, its venom contains a powerful neurotoxin that is dangerous to humans.
