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 ...

[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.
All octopuses have venom, but few are fatally dangerous. The greater blue-ringed octopus, however, is considered to be one of the most venomous animals known; the venom of one is enough to kill ten adult humans. [3] It uses the neurotoxin tetrodotoxin, which quickly causes respiratory arrest. Estimates of the number of recorded fatalities ...
