Cold Water
Giant Pacific Octopus
Enteroctopus dofleini · Cephalopod mollusk, family Enteroctopodidae; the largest octopus species known
The giant Pacific octopus is the largest octopus known, and meeting one at home in the emerald water of the Pacific Northwest ranks among cold-water diving's defining moments. An adult's arms can span a small room, yet the animal pours itself through den slots a fraction of that size; find the door by its midden, a fan of emptied crab and clam shells spilling down the spoil heap. Despite the scale it lives fast: a few years of relentless growth, one round of reproduction, and death, the female fasting for months while she guards and aerates tens of thousands of eggs. Encounters run from a watchful eye deep in a crevice to a bold animal walking the wall and tasting a diver's gear with sucker-lined arm tips. Let curiosity set the pace; never pull, pry, or crowd the den.

Dağılım: North Pacific rim: from California through British Columbia and Alaska across to Japan and Korea.

Yanında nasıl davranılır
Let curiosity run at the octopus's pace, keep hands out of dens, and skip lights in a brooding female's crevice: she cannot leave and stress costs her eggs.

Least Concern; taken in some regional fisheries and as bycatch, with local protections in parts of the range.
