This paper analyzes the composition, abundance and biogeographical relationship of the benthic polychaetes
collected in three shallow subtidal locations (mouth of Cuervo and Condor rivers and Acantilada Bay) from Aysen Fjord,
AF, Chile (45ºS, 73ºW), and provides a comparison with data on shallow soft-bottom polychaetes from Antarctica and other
locations of the Magellan Province: Dalcahue Channel, DC (42º22’S, 73º39’W), Puerto Cisnes, Puyuhuapi Channel, PC
(44º43’S, 72º42’W) and Magellan Straits, MS. AF polychaete fauna comprises 38 species, the macrobenthic taxon being
most representative in terms of abundance and species richness. The importance of polychaetes seems to be higher in fjords
than in channels. Low numbers of common species were detected among DC, PC, MS and AF, indicating differences along
the influence area of the Cape Horn Current or along the Magellan Province. The polychaetes from AF show low affinities
with Antarctica; maximum number of common species was observed with the Antarctic Peninsula, whereas the lowest values
were recorded from locations in the Ross and Weddell Seas. Coincidence in some ecological attributes between AF and
Antarctica indicate that polychaetes may play an important and similar ecological role in both environments.
