The leopard and cheetah co-exist together in Africa, while the jaguar typically lives elsewhere. The patterns of spots is different for each of these animals. The cheetah has simple black spots that are evenly spread. The jaguar has small spots that are inside the polygonal rosettes. And finally the leopard has rounder, smaller rosettes.
