Description:
The carapace and legs frequently have patterns or dots, while the body is typically dark, ranging from brown to purplish. Lighter-colored claws are possible, frequently with orange or reddish tinges on the lips. The width of the carapace is much larger than the length, and it is broad and rather rectangular. The rough carapace surface is frequently coated with tiny tubercles or microscopic granules. The carapace seems rough due to its frontal margin’s sharp serrations and multiple distinct lobes or teeth between the eyes. Compared to its walking legs, its chelae are larger and more robust One of these asymmetrical claws is frequently bigger than the other The powerful, blunt teeth on the margins of the claws are designed to smash prey, especially mollusks and crustaceans. The final set of legs is flattened to help cling to rough surfaces, and the walking legs are small and robust concerning the body’s length. The eyes of this species are frequently black, sometimes blending in with the carapace. Its more compact cye structures are probably an adaptation meant to lessen the possibility of harm from smashing waves or pebbles. This crab can swiftly identify possible prey and predators thanks to its incredibly acute eyes.
