Ommastrephidae
provided by wikipedia EN

Ommastrephidae is a family of squid containing three subfamilies, 11 genera, and over 20 species. They are widely distributed globally and are extensively fished for food. One species, Todarodes pacificus, comprises around half of the world's cephalopod catch annually.[1]

Some members of Ommastrephidae (volplaning species) are known to have the ability to glide out of water, earning them the common name of "flying squid".[2]

Description

The Ommastrephids are small to large squids, with mantle lengths ranging from that of the glass squid (Hyaloteuthis pelagica) at 9 cm (3.5 in),[3] to the Humboldt squid (Dosidicus gigas) at 1.5 m (4.9 ft).[4] The mantle narrows towards the back and possesses large terminal fins.[5] The family is characterized by an inverted T-shaped funnel locking cartilage.[2][5] They have an easily recognizable, slender, feather-shaped gladius with a hollow cone structure (the primary conus). Light organs (photophores) are present along the head and mantle of members of the subfamily Ommastrephinae.[2][5]

Ommastrephid arms have a double series of suckers. The enlarged tips (the clubs) of the tentacles have four rows of suckers, except in the genus Illex, which has eight. Hooks are absent. One of the ventral arms develops into a secondary sexual organ (the hectocotylus) in males.[1]

All ommastrephids are active predators. Their arms and tentacles bear sharp teeth and are used to grasp and bring prey to their beaked mouths.[6] They are very strong swimmers, and some species are known to glide out of water to escape predators.[2]

Ommastrephid paralarvae are distinctive for having fused tentacles, looking like a single "proboscis". 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).[2][6]

Distribution and habitat

Ommastrephids usually occur in pelagic waters, but can also be found in neritic habitats.[2] They are found worldwide.[1][6]

Ommastrephidae was first established by the Danish zoologist Japetus Steenstrup in 1857. It is classified under the suborder Oegopsina of the order Teuthida (squids). It is divided into three subfamilies - Illicinae, Ommastrephinae, and Todarodinae; further subdivided into 11 genera and more than 20 species.

These subfamilies, genera, species, and subspecies are classified under Ommastrephidae:

Description
provided by World Register of Marine Species
The family is characterized by an inverted T-shaped funnel locking cartilage, biserial suckers on the arms, tetraserial suckers on the tentacular clubs (except Illex which has 8 rows of suckers on the dactylus), buccal connectives that attach to the dorsal borders of arms IV, photophores in some genera, and a muscular bridge anterior to the funnel locking cartilage which passes from the funnel to the ventral surface of the head. The inverted T-shaped funnel locking cartilage easily distinguishes this family from all others, even in the youngest stages. One genus, Symplectoteuthis, has the funnel mantle cartilages fused at a single point, but they are otherwise typical. Three subfamilies are currently recognized: Ommastrephinae, Todarodinae, and Illicinae. The Ommastrephinae is distinguished by the presence of a central pocket (foveola) and several side pockets in the funnel groove, and by the presence of photophores which are often deeply buried in the tissue of the mantle, head and arms. It comprises five genera: Ommastrephes, Symplectogeuthis, Dosidicus, Ornithoteuthis and Hyaloteuthis.
