The carapace has a somewhat rounded look and is broad and squarish. The width is usually larger than the length, and it is comparatively smooth. Adults’ carapace widths range from 4 to 6 cm, though the size varies. The general coloring is sandy or light yellow, which frequently blends in nicely with the beach setting. This coloring aids with concealment. Depending on the habitat, the body may also have light brown or grayish tones. After being exposed to water or during the crab’s busiest nighttime hours, the coloring may somewhat darken. It has big eyeballs that stand out on long stalks. With the ability to spin, these stalks give the crab a nearly 360-degree view and an exceptional field of vision. Ghost crabs are characterized by their slightly curled eye stalks. Asymmetrical claws are present in both males and females, although they differ in size less than in fiddler crabs. The long, narrow legs are designed for quick movement over sandy terrain. The ability of ghost crabs to run swiftly across beaches is well-known. The tiny hairs on the legs aid in traction on the sand. The third pair of walking legs, which are unique to these crabs, are the longest and help them move quickly.
