Platyxanthus crenulatus is a species of crab in the family Platyxanthidae.[1] The species is found along the sublittoral zone of the western Atlantic in the waters of Brazil, Uruguay and Argentina,[2] associated mostly with hard bottoms. Adults are robust and conspicuous crabs, with a smooth carapace, dorsally purple and white ventrally. Their claws have marked heterochely and right-handedness (i.e. dimorphism between chelae and the tendency of bearing the major claw on the right-hand side of the body), traits associated with shell-breaking feeding habits.[3] Due to its abundance, large size and diet, P. crenulatus presumably has an important ecological role as a predator in benthic communities.[4]
