Abstract
Molluscs are originally originated in marine water, spread to freshwater and on to the land. Freshwater and landforms are almost equal to the marine forms. Molluscs primarily inhabit in the intertidal and littoral zones of the sea, occasionally descend to a greater depth upto 10,000 m. Molluscs belonging to different taxonomic groups have been exploited for food, pearls, and shells. The estimate number of species of molluscs vary from different parts of the world, however, estimates number of existing species are about more than 1,00000 (Haszprunar and Wanninger, 2012). About 5070 species have been reported from India belonging to 290 families and 784 genera which are recorded from Gulf of Mannar (428 species), Lakshadweep (424 spp.), Gulf of Kutch (350 spp.), Orissa coast (337 spp), West Bengal coast (425 spp.) and Andaman & Nicobar Islands (1434 spp). Nearly 3,370 species of molluscs are recorded from marine habitat (Venkataraman and Wafar, 2005). Among these, gastropods are the most diverse, followed by bivalves, cephalopods, polyplacophores and scaphopods. At present over 1.5 lakh tonnes of cephalopods, over 1 lakh tonnes of bivalves and nearly 20,000 t of gastropods are exploited from Indian waters. The large number of marine gastropods (19 species)
