Abstract

The present paper refers to the results ofbenthic surveys carried out between September 1982 and August 1983 in the area of Bahfa Blanca, province of Buenos Aires, Argentina. They include the composition and spatial distribution of the macrofauna, related to the granulometric characteristics of the sediments. The area was characterized by dominance of species, in spite of spatial and seasonal fluctuations. The correspondence between many abundant species and the granulometric characteristics of the bottom is related to their feeding habits. A gradual increase of deposit feeders in muddy sediments was observed.
