The member of this genus that best embodies the common name "giant octopus" is Enteroctopus dofleini, which holds the record of being the world's largest octopus based on direct measurements of a 71 kilograms (157 pounds) individual, weighed live. [7] [a] This octopus had a total length near
American zoologist G. H. Parker found that the largest suckers on a giant Pacific octopus are about 6.4 cm (2.5 in) and can support 16 kg (35 lb) each. [3] The only other possible contender for the largest species of octopus is the seven-arm octopus ( Haliphron atlanticus ), based on a 61-kilogram (134-pound), incomplete carcass estimated to ...
Megaleledone setebos, the giant Antarctic octopus, is a very large venomous octopus with a circum-Antarctic distribution. It grows to at least 28 cm in mantle length and 90 cm in total length. [1] M. setebos feeds by drilling small holes in large, shelled mollusks, and then injecting its toxic saliva.
Hatchlings of the giant Pacific octopus (Enteroctopus dofleini)—one of the two largest octopus species—weigh 0.0253 g (0.00089 oz) on average. [ 30 ] At the other extreme are nautiluses , which upon hatching typically have a shell diameter of 25 mm (1 in) or more (depending on the species), the largest hatchling size among extant ...
