Typically, it has a reddish or orange color, which can vary in intensity. The carapace is smooth, generally oval, and seems rounded because of its convex surface. Eleven big, round, white, or vellowish spots seven on the carapace and four on the legs are a noticeable pattern on the typically reddish or orange carapace. Its common name, seven-eleven crab, comes from this unique pattern. It is a comparatively large crab, with a carapace width of up to 15 cm. The big, strong chelipeds are designed to break open hard-shelled prey, such as mollusks. The claws are somewhat smoother than the rest of the body and frequently have a reddish-orange color similar to the carapace. The walking legs are sturdy, covered in smooth textures or tiny granules, and shorter than those of other crabs. With their distinctive white dots, the legs have the same coloration pattern as the rest of the body. The eyes have a good field of vision since they are situated at the front of the carapace and are rather tiny.
