In the case of the marine biodiversity of India, the number of species known could be of the order of 13,000 or higher (Ramakrishna and Venkatara¬man 2001). The family Polynemidea usually known as thread-fins; name resulting from the occurrence of numerous slim or slender filaments on the lower part of the pectoral fin, number and the nature of these free filamentous rays assist the systematic arrangement of species. Present studies deal with the overview, diversity and population density of the thread-fins (Family: Polynemidae) fishes of the south east coast of Tamil Nadu. The costal district of Tamil Nadu in the present study showed five fish species spread over 3 genera, 1 family and 1 order.
