A crab of the family Ocypodidae in the class Crustacea, with one of the male's claws abnormally large. The carapace reaches 3 cm in width, wide at the front and narrowing sharply at the back. It is dark blue-green in color with a purple mesh pattern in the center. The claws are reddish brown. It is found along the Ariake Sea coast to Kagoshima, Miyazaki, Tanegashima, the southern part of the Korean Peninsula, and northern China. The crab found in the Indian Ocean and South Pacific Ocean that was previously thought to be the same species is actually the closely related U. dussumieri or U. coarctata .
