The research has been conducted on April 2016. It aims to obtain the quantitative information concerning the distribution pattern and abundance of the Marine Hermit Crabs population. The applied research method is the descriptive method with the research design of belt transect and the hand sorting as the applied sampling technique. Sampling was carried out at the Littoral Zone at 6 stations with 5 plot squared for each station. The applied area of plot squared is 1 x 1 m. The taken data are the data of hermit crabs and the supporting data of environment. Data analysis includes the distribution pattern and abundance of the Marine Hermit Crabs population. Marine Hermit Crabs determination is carried out in the Research Center Laboratory of the Oceanography Indonesian Institute of Science Jakarta. Determination result obtains the 50 individuals of Marine Hermit Crabs consist of one family and 9 species, namely Aniculus erythraeus, Calcinus morgani, Calcinus laevimanus, Clibanarius corallinus, Clibanarius humilis, Clibanarius mergueinisis, Clibanarius striolatus, Clibanarius virescens, and Dardanus megistos. Research result shows that the abundance of the Marine Hermit Crabs population ranges of 1 ind/m2 – 2 ind/m2. In general the abundance analysis shows the low level of abundance. Morishita index shows the distribution pattern of Marine Hermit Crabs in Sindangkerta Beach includes the category of clustering (Id > 1) and uniform (Id < 1).
