Cephalopods assemblages from the southern Tyrrhenian Sea

The teuthofauna assemblages of the southern Tyrrhenian sea were studied utilising data derived from five International Medits bottom trawl surveys. A total of 25 cephalopod species were found between 18 and 652 m depth. The assemblages were analysed with Bray-Curtis similarity index. Four main groups were defined:inshore, shelf, slope and midslope. Alloteuthis media was the dominant species inshore, Illex coindetii on the shelf, Todaropsis eblanae on the slope, and Todarodes sagittatus for the last group.
