| Abstract |
The intertidal of Pangandaran is one of the tourist destinations on the southern coast of Java Island. The purpose of this study was to describe the diversity, distribution of invertebrate in Pangandaran Tourism, West Java Province, Indonesia. The sample were taken from eight site sampling locations from July 2017 to November 2018. Sample taken with line transect method and their diversity and distribution was analyzed by Morisita Index and Similarity Index. The research found 139 species spread to 12 classes and 7 phyla of invertebrate. A phylum of mollusca dominated with 71.2%, followed by Cnidaria with 7.9%. Faunus ater, Terebia sp, Clithon oualaniensis found dominant in muddy shore substrate, Cerithium breviculum, Thais jubilaea, Anthopleura elegentissima found dominant in rocky shore substrate and Hastula bacillus just found in sand shore substrate. Clibanarius vittatus is a cosmopolitan crustacea species found in every substrate characteristic with abundance (69 ± 15) ind.m-2. High diversity shows in rocky shore substrate with a range H’ (3.99–5.08) and low diversity shows on steep crag substrate with range H’ (0.50–0.65). The distribution of group categories by Morisita is dominant, while the cluster analysis of Bray-Curtis showed four clusters based on the difference of substrate. Diversity and abundance decrease of invertebrate communities influenced by pressure from anthropogenic activities, tourism activities, illegal trade fossil and invertebrate as live, capture and water pollution. |
