Intertidal zone is a heterogeneous environment due to its habitat composition and structure. It supportsthe highest diversity of flora and fauna. Organisms found in intertidal zone facephysical and chemical conditionsintensively during tidal periods. Gastropodscan be found in the terrestrial, freshwater,and marine environment. To date, there is a lack of documented information on the diversity of marine gastropodsin the intertidal zone of Oma Village, Central Maluku, Indonesia. The research objectives are to identify marine gastropod species and determine theirabundance and species diversity along three intertidal zone,namely Tuhurui, Sila and Hitalawa of Oma Village, Central Maluku,on March 2022. Sampling was done using transect line methods. At each study site, five transects line were laid perpendicular to the shore which 150 m in length each transect. Quadrat of 1 m2was placed along the transect line with an interval of 10 meter. A total of six ordo of marine gastropods (Lepetellida, Trochida, Cycloneritida, Littorinimorpha, Caenogastropoda and Neogastropoda) belong to 24 family and 92species found in this research. Number of gastropod species and its abundance varied between study sites. Intertidal zone of Hitalawa has the highest diversity index (H` = 3,482) compared to othersintertidal zone.Evenness index (J`) varied between J`=0,753 and J`=0,846. Neritidae and Muricidae are the predominant species in all study sites. Dominance index (D) varied between 0,051 and 0,086. Diversity index and evenness index of marine gastropod in thisresearch were higher and there was no dominant species in gastropod communities. This research contributes to mollusca species diversities in Maluku waters.
