Mole crabs belongs to the subphyllum of crustaceans and the super family of Hippoidae live in swash zones of the intertidal region. One of the most abundant is the species of Emerita emeritus at Glagah, Parangtritis and Parangkusumo beach south Java, live in the high-ferrous black beach sediment. The aim of research is to determine the relationship between length-weight, pattern of growth, sex ratio, and the relationship of the length-weight to organic matter, and the grain size diameter of the tree beaches. The research was conducted on April - June 2019 with purposive sampling method. Data analysis are length-weight correlation, content of organic matter, grain size diameter. The results showed that the growth patterns of male and female E. emeritus at Glagah, Parangtritis and Parangkusumo beach are allometric negative with a value of slope b <3. Male and female sex ratios at Glagah is 4: 1, Parangtritis is 0: 1, and Parangkusumo is 1:17. The length-weight correlation of E. emeritus to the dominant grain size diameter at Glagah with (r) : 0.98. While the correlation of length-weight of E. emeritus to organic matter with (r) : 0.55 as moderate correlation.
