Giant octopus

The Giant Octopus, are distinguished from other species of octopus by their sheer size. Adults usually weigh around 15 kg, with an arm span of up to 4.3 m. The mantle of the octopus is spherical in shape and contains most of the animal's major organs. By contracting or expanding tiny pigment-containing granules within cells known as chromatophores in its tissue, an octopus can change the color of its skin, giving it camouflage. This species of octopus commonly preys upon shrimp, crabs, scallops, abalone, clams, and fish. It is preyed upon by Harbor Seals, Sea Otters, and Sperm Whales.
