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.
इसे कहाँ और कब देखें
"निवासी" का अर्थ है कि उस गंतव्य पर अधिकांश डाइव्स में उनसे मुलाकात होती है; "मौसमी" का अर्थ है कि वे सूचीबद्ध महीनों में विश्वसनीय रूप से मौजूद रहते हैं; इसके अलावा जो भी मिले वह बोनस है, योजना नहीं।

इन्हें समझना
आवास: Rocky reefs, walls, and boulder fields with den crevices, from the intertidal to well past diver depths in cold, emerald water.
रेंज: North Pacific rim — from California through British Columbia and Alaska across to Japan and Korea.
व्यवहार: Lives only a few years, growing relentlessly to one round of reproduction; the female guards and aerates tens of thousands of eggs without feeding until she dies. Individuals range from reclusive to boldly curious.
आहार: Crabs, clams, shrimp, and fishes; the den is marked by a midden of emptied shells outside the entrance.
आकार: आमतौर पर लगभग 4.0 m; दर्ज अधिकतम गहराई 6.0 m (arm-span tip to tip; big animals commonly weigh 15–20 kg, exceptional ones far more).
इसके आसपास कैसे व्यवहार करें
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.
