Ninety cephalopod specimens were collected during the bottom trawl survey ATLANTIS 2009 undertaken between 24 February and 1 April 2009 The surveyed area was the zone between parallels 44◦and 48◦S, east of the Argentinean EEZ down to the 1500m depth on the HS of the SW Atlantic The collection was composed of 16 species of squids and 5 of octopods. 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
