These large octopuses can grow up to 33 lb, with an arm span up to 4.3 m (14 ft). They are commonly found in the coastal North Pacific, and prey on shrimp, crabs, scallop, abalone, cockles, snails, clams, lobsters, fish, squid, and other octopuses. Giant Pacific octopuses are considered to be long-lived compared to other species, with lifespans typically 3–5 years in the wild. They have been seen around the OOI Endurance Offshore infrastructure (600 meters depth), occasionally on top of or inside the benthic experiment packages (BEP).
