This paper presents the results on ten of the most important cephalopods species sampled during the DEMERSALES Spanish surveys form 1990 to 2011. The main species in biomass terms in this survey in decreasing abundance order were: curled octopus (Eledone cirrhosa), broadtail shortfin squid (Illex coindetii), lesser flying squid (Todaropsis eblanae), common octopus (Octopus vulgaris), long finned squid (Loligo forbesi), common squid (Loligo vulgaris), European flying squid (Todarodes sagittatus), pink cuttlefish (Sepia orbignyana), common cuttlefish (Sepia officinalis) and elegant cuttlefish (Sepia elegans). We present the geographic distribution and bathymetric abundance for these species. Length distributions of these species along the latest 5 years in the survey series are also presented and discussed.
