The Giant Pacific Octopus, or North Pacific Giant Octopus, is a very large cephalopod in the genusEnteroctopus. It lives in the coastal North Pacific, usually at a depth of around 65m (215 ft). It can, however, live in much shallower or deeper waters. It is arguably the largest octopusspecies, based on a scientific record of a 71kg (156-lb) individual weighed live. The alternative record is the seven-arm octopus, based on a 61kg (134lb) carcass estimated to have a live mass of 75kg (165lb). However, several more questionable size records suggest that E. dofleini is the largest of all octopus species by a considerable margin.
