This is a very common open water species which is frequently found in mangroves as well.

Males and females look very different, not only in colour but in body form. They are fully aquatic crabs and cannot live long outside water. Commercially very important, they are caught with traps and nets. Flower crabs are carnivores, coming in with the tide to hunt fish and other swimming animals in the mangroves.
