Gastropods are the class of molluscs invertebrate which play an important role in the ecosystem. Water resources is one that has a high diversity of species. This study aims to analyze the diversity of gastropods on mangrove forests in the region of North Sulawesi Bunaken National Park particular village Kumu and Molas. The research was conducted in October through December 2012, using descriptive methods. Sampling was conducted at two locations gastropods with each 5 point observations (transect with each 5 plots). Parameter observations include diversity, evenness, density, dominance and similarity, while the physical parameters include water temperature, air temperature, pH and salinity.The results showed that of 826 gastropods were found to be composed of 15 species, namely Vexillum sp, Cerithium tenuifilosum, Rhinoclavis kochi, Tectarius muricatus, Partner Coronata, Chicoreus capucinus, Nassarius dorsatus Nassarius distortus, Nerita planospira, Quoyia decollata, Terebralia sulcata, Telescopium telescopium, Faunus ater, Turbo bruneus and Lophiotoma pelytropa. Analysis of diversity in the village Kumu indeks is 1, 74, while the village of Molas namely 2.09, Kumu equity indeks 0.76, while Molas 0.92. Indeks Density and relative density is 3.16 ind/m2 Kumu village, while the village of Molas 3.45 ind/m2, then indeks Kumu dominance in the village in the village of Molas 0.03 and 0.01. While similarity index of 80%. From these results, the index of diversity in the grade being, being classified in equity index, the indeks for the village of Molas density higher than Kumu village, the next indeks dominance at both locations were classified low, then the indeks of the similarity in the two locations being considered.
