New record of a marine bivalve (Family: Pinnidae) from Chilika Lagoon, Bay of Bengal

Abstract

Present study describes the newly reported marine bivalve species <em>Atrina serrata</em> from the marine influenced region of Chilika lagoon. This is the first time ever to record an Atlantic bivalve species from the shallow coastal waters of Indian subcontinent. With the paucity of information, the study isn’t reached to any conclusion regarding the possible reason of occurrence, since multiple parameters are governing on the distribution of a species. However, this finding will help to understand the changed or changing benthic ecology of shallow water coastal ecosystem such as Chilika after opening of the lagoon inlets.
