Description:
The carapace has a smooth or somewhat grainy texture, and it is roughly oval and somewhat flattened. Its surface is generally even, with distinct lateral edges and a small central ridge. Usually, the legs and carapace have patterns or mottling in tones of gray, green, or brown. The chelipeds are strong and comparatively lengthy, with frequently comparable-sized claws on both feet. Their surface is smooth or slightly ridged, and their points are sharp and pointy, which they use for defense and feeding. The long, thin walking legs are designed for climbing and navigating rocky and mangrove conditions.The silky smoothness of the legs is enhanced by the sharp tips, which help with grip and movement. The big eyes are protected by retractable, short stalks that can be drawn into the orbits. The short antennae are situated in the space between the eyes. The abdomen is segmented, small, and tucked under the thorax.
