Introduction

         Sandy shores or beaches occur along the margin of the coastal seas of the world having considerable wave action, where the sand particles are not allowed to settle by the action of tides and waves. Vast stretches of the shores of the seas are bordered by such beaches of sand, receiving full force of waves. As this area is highly influenced by the ceaseless incoming and outgoing tides with pounding forces of the breakers, and due to its continuous shifting nature of the bottom, this intertidal area becomes an unfavourable place for inhabitation by the marine benthos. Thus, a sandy beach, quite in contrast to the rocky shore, at first glance, do not show any life on the surface of the sand and almost barren in appearance during low tide period.
