The number of freshwater species in the world is quite small when compared with the vast number of marine species. There are several marine forms which are penetrated brackish and freshwater but remain unable to breed there while others have adapted sufficiently to remain for their entire life span. Polychaetes are commonly found in Indian estuaries, among 152 species recorded, 119 species from the east coast, 10 species from both east and west coasts. A total of 8 species were identified along Thenkasi District. Macro benthic polychaetes highlighted the presence of indicator species at all stations. Most of the benthic studies explored that Nereididae is the dominant species. The polychaetes observed throughout this study were a similar size and this is a clear indication of extreme disturbance imposed on the sediment. The present findings show macrobenthic polychaete diversity rich all along the Thenkasi District of Tamil Nadu.
