Study about gastropods composition was conducted on March 2009 used quadrat line transect methods at 6 station. During the study, 32 species were collected consisted of 15 families with 223 total of individu. Density of individu ranged 2,9 - 6,7 ind/m2. Shannon-Wiener Diversity index (H’) ranged 1,68 to 2,29; Pielou evennness index (J’) was 0,81 to 0,95; and dominance index (C) was 0,12 to 0,24. Cluster similarity analysis was made to investigated the similarity among species each stations with the highest value between station 3 and 4 (0,67) and the lowest value between station 3 dan 5 (0,36).Keywords: Gastropods, Inner Ambon Bay, density, diversity Berkala Ilmiah Biologi. 2013.
