The macrobenthic community associated with the encrusting zoanthid Palythoa mutuki was studied in the littoral zone of four different sites situated along the coasts of Saurashtra (Gujarat, India). A total of 20 random quadrates (0.25 m2) were laid in the lower littoral zone where Palythoa mutuki was abundant. All the animals present in the quadrate area were collected or photographed and brought to the lab for species identification. A total of 67 different species belonging to 6 phyla were identified. The most abundant taxa were Arthropoda (44.8%), Mollusca (38.7%), Cnidaria (4.5%), Annelida (4.5%), Porifera (4.5%) and Echinodermata (3%). The maximum diversity of associates amongst the studied sites varied between 31 and 53 species, with the highest value recorded at Sutrapada followed by Dhamlej, Kodinar and Veraval. The diversity and species composition of associated community with P. mutuki, tested with MDS, PCA and Bray Curtis Similarity, is significantly homogeneous in all sites, with the exception of Veraval probably as a consequence of the habitat heterogeneity.
