The best represented groups were Histioteuthida (5 species) and Octopodidae(5). The most abundant species were Gonatusantarcticus(25.5%), Histioteuthisatlantica (11.1%), and Muusoctopuseureka (8.9%) The geographic and/or bathymetric distribution ranges of 9 species are extended, and this is the first record of Galiteuthis glacialis outside circumpolar Antarctic waters
