OCTOber Seventh: The Seven-Arm Octopus

Haliphron atlanticus,also known as the Seven-Arm Octopus, is one of the two largest species of octopus - right up there with the Giant Pacific Octopus. In fact, the single largest octopus ever documented was one of these amazing cephelapods - measuring in at 2.9 meters (9.5 feet) in length and weighing 61 kilograms (134.5 pounds). Their common name derives from the fact that the male of the species keeps its hectocotolys coiled up inside a sac beneath the right eye, giving it the appearance of only having seven tentacles.
