EUNICE PENNATA (POLYCHAETA: EUNICIDAE) FROM ACTIVE AND PASSIVE COLD SEEP SITES IN CENTRAL AND SOUTHERN CHILE (36°- 46°S)

| Sumario: | Examination of material from INSPIRE Expedition 2010 to the Chilean margin aboard the R/V Melville revealed large-bodied polychaetes of the species Eunice pennata (O.F. Müller 1776). It was collected with an Agassiz trawl at seven stations in central and southern Chile (36°-46°S) between 460 m to 906 m depth. This species was found living in crevices or in tubes associated to carbonate crusts derived from authigenic activity at active and passive cold seep sites. It differs from other closely related species by branchiae starting from setiger 3, and by the presence of ring-shaped bases in posterior notopodia. This is the first record of these species in waters of the Southeast Pacific shore, being formerly cited for the South Pacific coasts. |
