Black Rhinoceros

The Black Rhinoceros or Hook-lipped Rhinoceros (Diceros bicornis), is a species of rhinoceros, native to the eastern and central areas of Africa including Kenya, Tanzania, Cameroon, South Africa, Namibia, Zimbabwe, and Angola. 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" is a mistranslation of the Dutch word wijd for wide, referring to its square upper lip, as opposed to the pointed or hooked lip of the Black Rhinoceros. They are now often referred to as the Square-lipped (for White) or Hook-lipped (for Black) Rhinoceros.
The World Conservation Union (IUCN) announced on 7 July 2006 that one of the four subspecies, the West African Black Rhinoceros (Diceros bicornis longipes), has been tentatively declared as extinct.
