Title

Coral-grazing gastropods diversity in shallow reefs, Pulau Redang Marine Park, Terengganu, Malaysia

Abstract

The global deterioration of coral reefs has prompted research to comprehend the various
impacts on coral’s organisms as well as the interactions between reefs and their natural predators, coral grazing marine gastropods. However, the status of marine gastropods on Pulau Redang Marine Park is lacking. The study assessed marine gastropod diversity and shell morphometrics as indicators of the coral reef health ecosystem. SCUBA divers laid out a coral belt transect line of 50 m x 10 m at five sites. 177 individuals from four species of two families (Turbinidae and Muricidae; subclasses Vetigastropoda and Caenogastropoda) were collected at other locations. The highest number of individuals belonged to Drupella rugosa with 112 individuals, and the lowest number was Astralium rhodostomum. For the studied of marine snails, the Shannon index of diversity was H’=0.9 (<2) and the Simpson index of dominance was D=0.5 (<1). In addition, a high evenness, J’, and equitability Ep were recorded at the sites of Pulau Redang. In terms of morphometrics, A. rhodostomum had the highest value of shell length (28.49±7.06 mm) and shell width (26.63±5.21 mm). No gastropods were found in Chagar Hutang and Mak Simpan due to coral destruction caused by the cyclonic Pabuk storm in early January 2019. Although it is a baseline, future research should also focus on parameters such as seawater temperature and coral bleaching towards effects on corallivorous gastropods and interaction between gastropods species.
