Biggest octopus3/26/2023 Their range includes areas along the Pacific rim coastline, from Japan to California and north to Alaska and the Bering Sea. ![]() They also have two distinct and separate white dots near the front of their bodies, while the true giant octopus has either one spot or none. They are distinguishable from the giant Pacific species by a lack of longitudinal folds along their mantle and a frill or flap on their midline. Since their discovery in 2017 is so recent, scientists have yet to assign them a unique official Latin name. They are also quite large, and scientists consider them the third biggest octopus species globally, slightly smaller than seven-arm and giant Pacific octopuses. Recent DNA-based research has shown evidence that these creatures are a ‘genetic sister’ to the Giant pacific octopus, but that their lifestyles and habit selection may have given rise to its corporal differences. The nets of shrimp fishers often catch these octopuses, as they go after the same catch. Observers have long wondered about the origin of this octopus, with its distinguishing feature, an odd-looking frill or ledge. The frilled giant Pacific octopus is related to, but distinct from, the standard giant Pacific octopus. Frilled Giant Pacific Octopus ( Enteroctopus dofleini) Males and females are typically of similar size.Ī post shared by MBARI one of the largest octopuses ever discovered in the wild was a seven-arm caught in a fishing net dragged along the sea bed at a depth of nearly 1,000 feet. The seven-arm octopus is the second-largest octopus in the world, coming in with a maximum weight of about 165 pounds, with a length of around eleven feet. Seven-Arm Octopus ( Haliphron atlanticus) Though discerning their numbers is quite difficult, due to their short life span and reclusive habits, the population is relatively stable, and giant Pacific octopuses are observable throughout their range. They’re not nocturnal, but they seem to do most of their hunting at night, perhaps because their keen eyesight gives them an advantage over other predators and their prey. They subsist on shrimp, snails, scallops, lobster, fish, abalone, clams, crabs, other octopuses, or even small sharks. These giants are awe-inspiring to behold even when in captivity, but they are relatively short-lived, with a lifespan of only three to five years. The most enormous giant Pacific octopus ever measured was thirty feet long and tipped the scales at about 600 pounds. They typically weigh about 150 pounds, but the largest can be heavier and longer. This monstrous-sized octopus is the biggest globally, with an overall length over fifteen feet or more. Giant Pacific Octopus ( Enteroctopus dofleini) Dumbo Octopus (Enteroctopus grimpoteuthis)ġ.
