Aimere Beach is a beach located in the district of Ngada, Flores Nusa Tenggara East, and is a type of black sandy beach. The Aimere beach is not only used by fishermen but also as a tourist location, and there is a port as a means of transportation between the islands. There are many marine life that live in the Aimere Coast region; one of the biota found abundantly in the region is the gastropod. The degree of diversity of gastropods in an aquatic environment, especially in coastal waters, can be used as an indicator of pollution because these species have a high ability to adapt to their habitat. Therefore, this study aims to find out the diversity of gastropod species in the Aimere Coast region. Besides, to find out about the index of diversity, uniformity, and dominance of the gastropods in the Aimere Coast region. The method used is random sampling with samples taken from 3 stations, each consisting of 5 plot sizes of 1x1 m2. Data from the identification of gastropod species was analyzed using the diversity, uniformity, and dominance index formulas. The results of the research showed that the gastropod species found in the Aimere Coast region were 30 species belonging to 13 families. The index of diversity, uniformity, and dominance of the species of gastropods in the area of Aimère Coast is 2.8922, 0.8504, and 0.0738, respectively. These values indicate a high value of diversity, high uniformity, and a low value of dominance for gastropods.
