【 摘 要 】

The Sombu Beach is located in Wangi-wangi Island, Southeast Sulawesi, Indonesia. The beach is still natural and the substrates are dominated by fine sand and coral reef flat which is suitable for the habitats of gastropods. The aim of this research was to understand the diversity of gastropod in the intertidal zone of the Sombu Beach, Wangi-wangi Island. The research was conducted in January 2017 in the Sombu Beach, Wangi-wangi Island, Indonesia. The collection of the samples was conducted using quadrant plot method. Ten transects along the beach were made with four plots on every transect. So that, there were 40 plots data which were analyzed using Shannon-Wiener index of diversity (H'), evenness index (E), and dominancy index (D). The result of this research shows 13 species of classes Gastropods. The most abundant species in this study were Mitra sp. (86 individuals), Columbella sp. (40 individuals) and Conus sp. (35 individuals). The diversity index (H') was 1.8729, the evenness index was 0.7302, and the dominance index was 0.2071.
