The Canary Current Large Marine Ecosystem (CCLME) constitutes one of the four great marine systems of upwelling in the world, being the third in primary productivity and supporting the largest fisheries of the African coast, with an annual production of around 2-3 million tons (Valdés and Déniz-González, 2015). The cephalopod’s fauna of Northwest African region is diverse and abundant and includes species of wide distribution and elevated commercial value, among which are found squids, cuttlefish, and octopuses, whose catches in the area reach 80,000 - 120,000 tons per year. Although most of the fishery target species have been well studied, the knowledge of the unexploited species is very scarce (Rocha et al., 2017). Between 2002 and 2012 the Spanish Institute of Oceanography (IEO) and the FAO carried out eleven multidisciplinary surveys in northwest Africa, covering the shelf and continental slope from Morocco to Guinea. Quantitative data by species and important collections of benthic and pelagic cephalopods were gathered in 1334 trawl stations over the soft bottoms between 20 and 2000 m depth. Besides, oceanographic data were recorded in 1180 stations by different CTD devices. Almost 140 species have been currently identified. Among them, Sepiidae, Lolliginidae and shallow-water octopus dominate the coastal assemblages, while at the slope waters Ommastrephidae and deep‐water octopuses are more abundant. The collections and databases taken during these 11 trawl surveys represent an exceptional source of regional information on the biodiversity, composition, and distribution of cephalopod’s assemblages inhabiting North-west African continental margin.
