The orbits are rather large, their width being more than one-third that of the front. External maxillipeds free from hair on the surface; the sternum and the surface of all parts of the appendages except the hands are smooth. Chelipeds equal, the upper edge of the merus and hand strongly and sharply carinate; the fingers fluted as usual. Legs with crested edges to the long joints.

Economic Importance and Threats
Importance:  Dangers
(Poisonous. It is still not known how they accumulate the toxins, most of which are similar to those in puffer fishes (neurotoxins), or why they themselves are immune to it. These toxins cannot be destroyed by cooking, and are extremely potent. The toxins are in the flesh and cannot be transmitted if one is pinched by the claws. Most of poisonous crabs have very bright warning colours, and it is a good practice to avoid eating them.)
