Abstract

The present study illustrates the insufficient taxonomy records and highlights the use of microscopic diagnostic tool in polychaete taxonomy. It leads to a better understanding of coral-associated polychaete taxonomy in Great Nicobar Islands, India. A total of 24 species under 14 genera, 7 orders, and 11 families were identified, in spite of 3 species of Phyllocidae, 8 species of Nereidae, 5 species of Eunicidae, 2 species of Spionidae, and 1 species of Opheliidae, Sabellariidae, Terebellidae, Polynoidae, Amphinomidae, and Sabellidae. The current status of taxonomic information varies greatly among taxa and among geographic areas within taxa. The problems encountered included nomenclature, diagnoses, and determination of taxonomic relationships. We provide examples of a variety of these problems. Each species has distinct features of the particular families, and taxonomic section to assist the polychaete identification that is necessary to assess the biodiversity and taxonomy at any level. This chapter considers the importance of monitoring biological diversity, current morphological taxonomy of polychaetes and describes the approach developed for protected areas in Great Nicobar Islands.
