Coconut octopus is an astonishing creature which is native to the sandy bottoms in bays or lagoons of the Pacific ocean. It is also known as veined octopus and biologically named as Amphioctopus marginatus having a surprising feature of frequently burying itself in the sand with only its eyes uncovered. Coconut octopus commonly preys upon shrimp, crabs, and clams, and displays unusual behaviour, including bipedal walking and gathering and using coconut shells and seashells for shelter. The main body of the coconut octopus is typically around 8 centimeters (3 in) in size, and, with arms, approximately 15 centimeters (6 in) long. The octopus displays a typical color pattern with dark ramified lines similar to veins, usually with a yellow siphon. The arms of coconut octopus of the Pacific ocean are usually dark in color, with contrasting white suckers. In many color displays, a lighter trapezoidal area can be seen immediately below the eye of this astonishing creature.
