A recent research paper in The Journal of Crustacean Biology reveals a new genus and new species of tree crab in Kerala, southern India. Known scientifically as the “Kani maranjandu,” it is substantially different from other congeners. Its distinguishing characters include: the structure of its hard upper shell, as well as its male abdominal structure and reproductive parts, and of course, its diagnostic elongated walking legs, which no other genus has.
