Alacia hettacra (Müller, G.W., 1906)
Records: 287
This is the most abundant and commonly encountered species in open water to the south of the Subantarctic and Polar Fronts. It is most abundant at mesopelagic depths and relatively less abundant in the epipelagic. Kock (1992) reported seasonal and ontogenetic migration in this species along the Antarctic Peninsular with the early juvenile stages occupying deep water in autumn and then migrating up towards the surface at the end of winter. He also notes there is very little overlap between the distribution of this species and Alacia belgicae.
