The major neurotoxin component of the blue-ringed octopus is a compound originally known as "maculotoxin"; in 1978, this maculotoxin was found to be tetrodotoxin, [17] a neurotoxin also found in pufferfish, rough-skinned newts, and some poison dart frogs; the blue-ringed octopus is the first reported instance in which tetrodotoxin is used as a ...
What makes this octopus famous is its venom. Saliva glands of the southern blue-ringed octopus produce the deadly neurotoxin, maculotoxin. [10] The neurotoxin, tetrodotoxin (TTX), is secreted in the posterior salivary gland, which is located in the intestinal blood system of the octopus. This may provide the toxin into its bloodstream.
The greater blue-ringed octopus, despite its vernacular name, is a small octopus whose size does not exceed 10 centimetres (3.9 in), arms included, with an average weight of 80 grams (2.8 oz).

Many species of octopus, squid, and cuttlefish make use of venom when hunting their prey. The blue-ringed octopodes ( Hapalochlaena spp.) produce tetrodotoxin , which is extremely toxic to even the healthiest adult humans, though the number of actual fatalities they have caused is far lower than the number caused by spiders and snakes, with ...
When the octopus is approached, it may extend an arm to investigate. 66% of Enteroctopus dofleini in one study had scars, with 50% having amputated arms. [111] The blue rings of the highly venomous blue-ringed octopus are hidden in muscular skin folds which contract when the animal is threatened, exposing the iridescent warning. [112]
