Giant Pacific octopuses live up to their names. While they average 90 pounds, theyâre known to weigh up to 150, with the largest authenticated weight coming in at 156 pounds. And their arm spans can be up to an incredible 20 feet acrossâabout the height of a two-story building. Giant Pacific octopuses have huge appetites. Their diets consist of crustaceans (Dungeness crabs are a particular favorite); mollusks such as clams, squid, and even other species of octopus; and fish. In the wild, their rocky dens can be recognized by the piles of discarded shells just outside the entrances.
