Molluscs constitute a major group in the animal kingdom. In number of species, the mollusca is the second largest phylum after arthropoda. About 1,00,000 living species of molluscs are reported to be occuring in the world. They occupy almost all possible habitats - marine, brackish water, freshwater, land and also arboreal in some groups. India harbours an approximate total of 3,271 species of molluscs spread over nearly 591 genera and 220 families (Mitra and Dey, 1992). On the other hand, a checklist of molluscs of Indian estuaries includes a total of 245 species (120 gastropods and 125 bivalvs) [Subba Rao and Surya Rao ,1985]. They play a significant role in maintaining the steady state of the mangrove ecosystem and enhance its biological potentiality. Molluscs constitute an important faunal component in the food web of any estuarine-marine coastal environment. Previously several taxonomic and ecological survey of estuarine-marine molluscs of India was conducted by several workers (Banford,1867; Annandale and Kemp, 1916; Annandale and Prasad, 1919; Subba Rao et al., 1983; Subba Rao et al., 1992, Khalua et al., 2003). The present study deals with the taxonomic survey (34 species, 24 genera, 22 families and 9 orders) of intertidal macrobenthic molluscs.
