There were 3 stations chosen by purposive samplingmethod. Each station was made 100m line transect. Each transect consist of 4 plots measuring 3m x 3m with the distance was 25m between low and hing waters. Samples were analyzed in the biology laboratory of Marine Science Departemen Riau University. Result show that the highest density of the snailswas at station II (4.92 ind/m²) fallowed by stations III (2.25 ind/m²) while the  lowest density was at Stations I (1.3 ind/m²). There is a very strong relationship between organic sedimen content and density of C. quadrata( ). Keywords: Cerithidea quadrata, Distribution, Density, Mangrove, Anak Setatah
