The purpose of this study was to determine the community structure of gastropods in the mangrove ecosystem in Pulo Sarok Village, Singkil District, Aceh Singkil Regency, Indonesia. This research was conducted in April 2018 located in the coastal mangrove ecosystem of Pulo Sarok Village, Singkil District, Aceh Singkil Regency. The purposive random sampling was used in this study.

The highest density (D) was found at station 3 with a value of 2.44 Individuals per m −2 . The diversity (H ') obtained from the three stations ranged from 0.50 to 1.77 which was categorized a the low and medium levels. Evenness index (E) from 0.14 to 0.37 which were in the low category. Furthermore, Domination index (C) of Gastropods range from 0.32 - 0.83. The level of similarity index (IS) ranges from 85.71% - 100%. It is concluded that based on the biological indices the structure of the Gastropods community in the Pulo Sarok Village is at the poor category.
