About this species

Leptarma leptosoma, also known as the arboreal crab, is an arboreal, leaf-eating mangrove crab, from East and South Africa where it is found on Rhizophora mucronata and Bruguiera gymnorhiza, but not on Avicennia marina. It occupies an ecological niche similar to that of another sesarmid, Aratus pisonii, from the Americas.
