This research was aimed to determine the habitat characteristics, density and distribution patterns of P. acutidens . It used survey method and sampling location determined by purposive sampling. Measurement of water quality was done by in situ and ex situ which consist of physics and chemical parameters. Habitat characteristicsof P. acutidens was muddy sand,  and sandy mud . Sediment organic matter was high 10,60-14.85%. The water quality parameters were still support for the life of the P. acutidens. The average density was 1,8-4.2 ind/m2. The highest density was in middle zone and the lowest in upper zoneof the Intertidal. The distribution pattern was grouping. While highest size of individual P.acutidens found 7cm.Keyword: Habitat Characteristics, Density, Distribution Patterns, P. acutidens.
