They are asymmetrical in both claws, with fine scaly protrusions on the surface of the wrist segment, a strong spine in the inner end horn, and a small spine at the base; the length of the palm of the large claw is about 1. 5 times, the inner edge of the two fingers has blunt teeth of uneven size, and when combined, there is almost no gap between the two fingers.
