Cephalopod eight or ten. Decapods such as cuttlefish and squid have five pairs. The longer two, termed "tentacles", are actively involved in capturing prey; they can lengthen rapidly (in as little as 15 milliseconds). In giant squid they may reach a length of 8 metres. They may terminate in a broadened, sucker-coated club. The shorter four pairs are termed "arms", and are involved in holding and manipulating the captured organism. They too have suckers, on the side closest to the mouth; these help to hold onto the prey. Octopods only have four pairs of sucker-coated arms, as the name suggests, though
Little flying squid Japanese flying squid. It also has relatively small fins which only have a length equivalent to 25 to 31% of the mantle length (35-40% in the Japanese flying squid). 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
