    Abstract

    Polychaetes are one of the major benthic group of animals just like molluscs and crustaceans. Globally 12,620 species of Polychaetes are supposed to be occurring and in India around, 1,093 species representing 8.66% of the total number of polychaete species are known. Polychaetes are very important in the marine and brackish water ecosystems extending from the abyssal depths to the inter-tidal regions. Its major role is through the biomass formation in the benthic as well as in the pelagic aquatic systems as sedentary and pelagic polychaetes and through the different larval forms released by them. It also forms the major food for crustaceans, molluscs as well as for fishes. Because of the special adaptive nature of this group, Polychaetes are distributed in almost all ecological conditions, both in the macro and micro environments having different ranges of salinities and dissolved oxygen. Certain species survive in the anaerobic conditions also.
