Black Rhinoceros

The Black Rhinoceros (Diceros bicornis), also colloquially Black Rhino, is a mammal in the order Perissodactyla, native to the eastern and central areas of Africa including Kenya, Tanzania, Cameroon, South Africa, Namibia and Zimbabwe. Although the Rhino is referred to as black, it is actually more of a grey/brown/white color in appearance. The name of the species was chosen to distinguish it from the White Rhinoceros (Ceratotherium simum). This is misleading, as those two species are not really distinguishable by color. The word white in the name "White Rhinoceros" derives from the Afrikaans word for "wide" rather than the color white.
About 3600 Black Rhinoceros exist in the world.
