The front pairs of legs are long, but the hind legs are shorter and are used to carry on the back a variety of objects and organisms, especially valves of bivalves, by which these crabs camouflage and protect themselves.[4] It has been described as a decorator crab despite not belonging to the superfamily Majoidea.[5]
