Abstract

Benthic organisms in Universiti Malaysia Sabah (UMS) beach in Sepanggar Bay were collected along eight transects in the intertidal zone during the sampling period. A total of 36 species of benthic organisms from 28 families were collected. The distribution and the heterogeneity of the community were low due to high collection pressure from surrounding communities on edible and marketable species such as sea cucumber and bivalves. Umbonium vestiarium dominated the Study Area One, while in Study Area Two, the Clibanarius and un-identified gastropod has found to dominate the area. Umbonium vestiarium possible to the environmental indicators for organic matter pollution. The differences in the organic matter resistance can be found according to the distribution of both classes. Shannon-Weiner index show the low heterogeneity (0.5515) in the UMS beach community indicating the presence of dominant species. Evenness index Pielou's, J' values range between 0-1. Lower index value (0.3544) in UMS beach also indicates the dominance of certain species in sampling.
