The Antarctic neosquid is the only neosquid in the genus Alluroteuthis. The tentacles are relatively short compared to the arms.
Distribution
Alluroteuthis antarcticus occurs in from depths of 0–2,800 m (epipelagic and mesopelagic waters), and paralarvae can be found in the upper 200 m (epipelagic waters). ==Ecology==
Ecology
It preys upon Antarctic krill, Antarctic silverfish and other squids. However, Isotopic evidence suggests a diet in prey that are likely mesopelagic zooplankton that feed on sinking organic matter. ==References==
