About the Black Rhinoceros

Black rhinos live in eastern and southern Africa, in bushy plains, thick brush, open forests and grassy plains, always near water. Adults weigh up to 3,000 pounds. They are browsers that use a pointed, grasping upper lip to strip leaves off thorny bushes like acacia. Both black and white rhinos are actually gray; their color can depend on the mud they've rolled in.^[1]
