We studied that the environmental characteristics and the factors on the habitat of mud shrimp and ghost shrimp. The mud shrimp, Upogebia major and Ghost Shrimp are an abundant intertidal invertebrate of the west coast of Korean bays and estuaries where they live commensally with the cultured manila clam, Ruditapes philippinarum. And the geochemical characteristics (Mean grain size, COD, ignition loss, AVS, C/S ratio, C/N ratio and depth profile of sediments) on the burrow wall of the mud shrimp, Upogebia major and Ghost Shrimp were determined with those in surrounding non-borrow sediments of tidal flats. And Chlorophyll a content was no significant difference between burrow wall and non-burrow sediments. The C/S ratio showed that survey areas had anoxic or sub-anoxic bottom conditions. These results suggest that fresh organic matter in the burrow wall is supplied from tidal flat surface. Therefore, The Ef and Igeo of the metals proved that habitat characteristics can be classified as heavily to moderately polluted, respectively.
