Its common name comes from the relatively large size of its blue rings (7 to 8 millimetres [0.28 to 0.31 in] in diameter), which are larger than those of ...
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.
Blue-lined octopuses are known to be nocturnal hunters, while other species in the genus such as the greater blue-ringed octopus (H. Lunulata) is known to be diurnal hunter. Prey for blue-lined octopuses mostly consists of crustaceans and stomatopods, however in captivity they have been recorded to eat live fish, suggesting they do in the wild ...

The blue-ringed octopus's rings are a warning signal; this octopus is alarmed, and its bite can kill. [112] Some molluscs sting or bite, but deaths from mollusc venoms total less than 10% of those from jellyfish stings. [113] All octopuses are venomous, [114] but only a few species pose a significant threat to humans.
