It is classified under the suborder Oegopsina of the order Teuthida (squids). Ommastrephidae was first established by the Danish zoologist Japetus Steenstrup in 1857. Ommastrephids usually occur in pelagic waters, but can also be found in neritic habitats. It gradually splits into two as the paralarvae grow becoming completely separated once they reach mantle lengths of 5 to 10 mm (0.20 to 0.39 in). Ommastrephid paralarvae are distinctive for having fused tentacles, looking like a single "proboscis". ![]() They are very strong swimmers, and some species are known to glide out of water to escape predators. Their arms and tentacles bear sharp teeth and are used to grasp and bring prey to their beaked mouths. One of the ventral arms develops into a secondary sexual organ (the hectocotylus) in males. The enlarged tips (the clubs) of the tentacles have four rows of suckers, except in the genus Illex, which has eight. Ommastrephid arms have a double series of suckers.
