Giant Pacific Octopus

Fascinating facts about the Giant Pacific Octopus

• Adults usually weigh around 15 kg (33 lb), with an arm span up to 4.3 m (14 ft). The biggest recorded specimen tipped the scales at 600 lb (270 kg) and stretched a radial span of 32 ft (9.8 m). Its suckers are no joke, British zoologist G. H. Parker measured the largest at about 6.4 cm (2.5 in) and found each can hold 16 kg (35 lb).
• It has also been observed to catch spiny dogfish (Squalus acanthias) up to 1.2 m (4 ft) in length while in captivity. In May 2012, amateur photographer Ginger Morreau photographed a wild giant Pacific octopus attacking and drowning a seagull, proving the animal will seize any prey that fits its size range, even birds. These feats reveal a predator with a flexible diet that can shift to unexpected food sources, helping it survive in the variable deep-sea buffet.
• E. dofleini remain stationary or in hiding 94% of the time, usually concealed within dens, kelp, or camouflaged in their environment. When it does move, it uses jet propulsion, drawing water into its body cavity and forcefully expelling it through a siphon to generate a powerful thrust.
• Unlike most other octopus species, whose lifespans normally last only one year, the giant Pacific octopus has a lifespan of three to five years. It can lay between 120,000 and 400,000 eggs, each glued to a hard surface by the female. The mother then starves, living off her own body fats for roughly 6 months before dying once the hatchlings emerge.
• Following its DNA analysis, the giant Pacific octopus may actually prove to be three subspecies (one in Japan, another in Alaska, and a third in Puget Sound). The world's largest octopus, still called the giant Pacific octopus, is now known to comprise more than one species, according to new research led by an undergraduate at Alaska Pacific University. The newly documented frilled giant Pacific octopus has two distinctive white marks on its head.
