Abstract

Rocky shores are important ecosystems that supports the wide variety of plants and animals and are characterized by the zonation of species. This three months study was conducted in order to recognize the community structure and zonal distribution of macro fauna at the Manora rocky shore. The sampling was done monthly for three months in the year 2014 at three tidal zones, i.e. High tide zone, Mid tide zone and Low tide zone and a zonal comparison of fauna was performed to identify the distribution pattern of species during pre-monsoon season. A total 1318 individuals belonged to 68 species were identified and counted. The phylum Mollusca was the most diverse phylum which represented by 43 species, followed by Arthropods (16 species), Echinoderms (4 species), Annelids (2 species), Cnidarians (2 species) and Porifera (1 species). The highest faunal diversity (H’= 1.429) was observed at the low tide zone, but the diversity of molluscs was high (H’=1. 329) at the mid tide zone.
