Ommastrephinae is a subfamily of squids under the family Ommastrephidae.

Description

Ommastrephinae includes the largest species of squids belonging to the family Ommastrephidae, Humboldt squid ( Dosidicus gigas ) which can grow to 1.5 metres (4.9 ft) in mantle length (ML). ^[3] It also contains the smallest squid species belonging to the family, the glass squid ( Hyaloteuthis pelagica ) which has a mantle length of only up to 9 cm (3.5 in). ^[4] Ommastrephinae are mostly pelagic members of the family Ommastrephidae. Some species of the subfamily (notably Sthenoteuthis and Ommastrephes ) are known for their behavior of leaping out of the water (hence the common name 'flying squid'). ^[5]

Taxonomy

The name of the subfamily, like the family itself and the type genus Ommastrephes , comes from Greek ὄμμα ('eye') and -strephes ('rolling'). ^[6] They were first described by H.J. Posselt in 1891.
