Sponge is one of the components on the coastal and marine ecosystems, especially coral reefs and seagrass beds. Climate change and environmental conditions can affect the life of the sponge. The study is conducted to determine the distribution of the composition and density of sponge using belt transects (transect quadrant) with a size of 5x5 m, then count the number of each type of sponge contained in the transect. Study site divided into three (3) zones indicating different conditions of eutrophication. A total of 49 species were identified from 16 families of 8 orders. Composition and density of the sponge in inner zone as many as 11 families with a density of 0.96 ind/m2, and lower compared to the composition and density in the middle zone and outer zone. This is related to the difference in environmental conditions of the three zones based on eutrophication conditions.
