Abstract
Twenty two species of marine polychaete were collected in six types of substrates incluing rocks, scleractinian corals, demospongean sponges, soft bottoms, brown and red algae and Thalassia testudinum in July and August, 1986. Cluster analysis showed little affinity among those substrates, although some species such as Ehlersia cornuta, Haplosyllis spongicola, Nicolea modesta, Eupolymnia crassicornis and Notomastus latericeus were indentified in several substrates. The greater abundance and species richness of polychaetes was directly related to the heterogeneity and the organic matter contents of sediments. The most abundant species was Capitella capitata, wich may be important as an organic pollution indicator.
