Samples were stratified randomly taken on three kinds of substrates: on sand and coral substrates on the west, sand substrates in the middle and hard sandstone on the east, each of which consist of five quadrates of 40 cm x 40 cm. Results of this research showed that on the site have been successfully identified 17 species of macrozoobenthic fauna. None of them were classified as protected species. The macrozoobenthic fauna on Parerenan beach had a medium level of index of diversity (IK = 2,598). This meant that, the beach ecosystem in Pererenan was in a stable condition with a medium level of diversity. From the benefit and problems related to their occurrence, it can be described that macrozoobenthic organisms on this study sites, some can be consumed.
