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).[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:

gollark: Because you can discuss things without liking them?
gollark: There's no technical reason they should only last 8ish years.
gollark: Primarily batteries, and kind of screens if you're prone to dropping them a lot like me. Also charging ports.
gollark: Some parts tend to degrade over time, and I'd definitely want those to be swappable.
gollark: I at least want hardware I can actually replace/upgrade parts in.
