Camouflaged Octopuses Walk On Two Tentacles

If you are using your limbs to disguise yourself, how do you flee danger without giving yourself away? The answer, when you have eight arms, is to use six arms for disguise and to walk across on the seafloor on the other two. Defying the notion that bipedal motion requires muscles attached to a rigid skeleton, the octopuses used the strong, flexible muscles in their back arms to walk across the seabed when pursued by camera-wielding biologists. The two species have slightly different strategies. Octopus marginatus from Indonesia wraps itself into a ball while walking, perhaps to imitate a coconut rolling with the current. Tiny Octopus aculeatus of Australia holds up six of its arms to disguise itself as a clump of seaweed, while walking at up to 14 centimetres per second — faster than it can manage using more than two arms
