It has a cylindrical, muscular body, typical of related species, which tapers to a short, pointed tail. Its fourth right arm bears a hectocotylus on the distal half and has 11-13 normal suckers on its basal portion, ventral trabeculae which are broadened and joined forming low serrated fan with approximately 20 pairs of trabeculae. The second and third arms on each side are longer than the first and fourth arms being
