Colossal squid
The largest recorded specimen was captured in 2007 by a New Zealand fishing boat off Antarctica. It was initially estimated to measure in length and weigh . The squid was taken back to New Zealand for scientific study. A study on the specimen later showed its actual weight was , but it only measured in total length as a result of the tentacles' shrinking "post mortem".
Ommastrephinae
Ommastrephinae includes the largest species of squids belonging to the family Ommastrephidae, Humboldt squid ("Dosidicus gigas") which can grow to in mantle length (ML). 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 . 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').
