Meanings

Any member of any species of the genus Hapalochlaena of octopuses, with distinctive blue rings, that carry the highly poisonous venom tetrodotoxin (TTX).
In terms of diversity, cephalopods include the egg case making argonauts, shelled nautiluses, venomous blue-ringed octopuses and enigmatic giants like the giant and colossal squid. […] The blue-ringed octopus Hapalochlaena lunulata has tetrodotoxin, the deadly toxin it also releases in a bite, in their ink but the concentrations and effect in inking are not known.
