The teuthofauna assemblages of the Southern Tyrrhenian Sea are identified by data from five trawl surveys. A total of 139 hauls were carried out in late spring or the middle of summer between 1995 and 1999, and 25 cephalopod species were found between 18 and 652 m depth. The assemblages were analysed with the Bray-Curtis similarity index. Depth showed a positive correlation with cephalopod distribution. Four main cephalopod groups were defined: inshore (10-100 m), shelf (101-200 m), slope (201-600 m) and midslope (350-600 m). Loligo media was the main species for the first group, Illex coindetii for the second, Todaropsis eblanae for the third group and Todarodes sagittatus for the last group.

Abstract
The teuthofauna assemblages of the Southern Tyrrhenian Sea are identified by data from five trawl surveys. A total of 139 hauls were carried out in late spring or the middle of summer between 1995 and 1999, and 25 cephalopod species were found between 18 and 652 m depth. The assemblages were analysed with the Bray-Curtis similarity index. Depth showed a positive correlation with cephalopod distribution. Four main cephalopod groups were defined: inshore (10-100 m), shelf (101-200 m), slope (201-600 m) and midslope (350-600 m). Loligo media was the main species for the first group, Illex coindetii for the second, Todaropsis eblanae for the third group and Todarodes sagittatus for the last group.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
