European squid propulsion. The posterior border is slightly concave. The head is relatively small and has large eyes which are covered with a transparent membrane. Like almost all squid, this species has ten limbs surrounding the mouth and beak: eight are relatively short arms, and two, which form the tentacles, are long, as they are used to catch prey. The fourth left arm of males is a hectocotylus. The European squid can grow up to 30–40 cm in the mantle length, but more usually they are 15–25 cm long. The males are generally bigger than the females and exhibit more rapid rates
Little flying squid slightly less than half of the mantle length. The largest arm suckers have 9-11 sharp different sized teeth on distal two thirds of their rings. The height of the protective membrane on the arms is uniform and it is not higher than that of the suckers. The manus of the tentacles has 6-8 sucker rows in four series and the rings of the medial suckers on the manus have 16-18 moderately large, subconical teeth which alternate with low plates and are around 2.5 times largers than the marginal suckers in diameter. On the tentacles the protective membranes extends to the
