Abstract
Micromolluscs constitute an important part of the biological communities that inhabit sandy shores. In order to determine health of a particular sandy beach, these micromolluscs can be used as a good indicator. Present paper, which form first of the series on the subject, describes micromollusc communities found on the sandy beach at Ras Zarrin which is located south of Pasni. Preponderance of bivalves was noticed on this high energy beach followed by gastropods and scaphopods. Amongst bivalves, Chione imbricata seems to be the most the dominant species followed by Didimacar tenebrica. Among gastropods Turritella columnaria seems to be dominant. Scaphopod was represented by Dentalium octangulatum and Laevidentalium longitrorsum, the former being dominant. The paper also describes size distribution of major taxa and enumerates micromolluscs being preyed upon by naticid and muricid gastropods.
