Description

Ommastrephinae includes the largest species of squids belonging to the family Ommastrephidae, Humboldt squid (Doscidicus gigas) which can grow to 1.75 metres (5.7 ft) in mantle length (ML).[2] 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).[3] Ommastrephinae are mostly pelagic members of the family Ommastrephidae. All species of this subfamily contain photophores whose locations vary by species. Some species of the subfamily (notably Sthenoteuthis and Ommastrephes) are known for their behavior of leaping out of the water (hence the common names 'flying squid').[4]

Taxonomy

The name of the subfamily, like the family itself and one if its member genera, Ommastrephes, comes from Greek ὄμμα ('eye') and -strephes ('rolling').[5] They were first described by H.J. Posselt in 1981.

List of genera

Eight species of squids are recognized under Ommastrephinae, divided among six genera. They are the following:

  • Genus Dosidicus
    • Dosidicus gigas, Humboldt squid, jumbo flying squid or jumbo squid
  • Genus Eucleoteuthis
    • Eucleoteuthis luminosa, striped squid or luminous flying squid
  • Genus Hyaloteuthis
    • Hyaloteuthis pelagica, glass squid or glassy flying squid
  • Genus Ommastrephes
    • Ommastrephes bartramii, neon flying squid or red flying squid
  • Genus Ornithoteuthis
    • Ornithoteuthis antillarum, Atlantic bird squid
    • Ornithoteuthis volatilis, shiny bird squid
  • Genus Sthenoteuthis
    • Sthenoteuthis oualaniensis, purpleback squid or purpleback flying squid
    • Sthenoteuthis pteropus, orangeback squid or orangeback flying squid
