Episesarma is a genus of swimming crabs species in the family Sesarmidae. Wikipedia
Features: Body width 4-5cm. Body flat and squarish, legs flat with pointed tips. Pincers may be colourful. The sides of the body have a structure with a net-like pattern that help recirculate and oxygenate water in the gill chambers. In this way, these crabs can breathe air and stay out of the water for some time. WildSingapore
