846-855Community dynamics of gastropods were studied from four selected intertidal locations along an18km long coastal stretch on the east coast of south Andaman Islands. A total of 71 taxa belonging to 17 families and 3 orders were identified. While Nassariidae (31.15%) made maximal contribution to faunal abundance, Muricidae (11 species) and Conidae (9 species) were mainly responsible for changes in diversity patterns. In general, abundance and diversity exhibited a reversing trend. Most diverse area (H’=1.816±0.49 and d= 2.68±0.97) was found in the middle of the southeast coastal stretch. Multivariate analysis revealed the presence of location-specific gastropod assemblages spearheaded by Nassarius spp. and Nerita spp. The results yielded a potential positive correlation between locations and gastropod diversity along the entire coastal stretch
