The Black rhinoceros or Diceros bicornis or, hook-lipped rhinoceros is a species of rhinoceros, native to eastern and southern Africa including Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia, and Zimbabwe. Although the rhinoceros is referred to as black, its colors vary from brown to grey.
The Black rhinoceros or Diceros bicornis can also be distinguished from the white rhinoceros by its size, smaller skull, and ears; and by the position of the head, which is held higher than the white rhinoceros, since the black rhinoceros or Diceros bicornis is a browser and not a grazer.
This key differentiation is further illustrated by the shape of the two species mouths (lips): the “square” lip of the white rhinoceros is an adaptation for grazing, and the “hooked” lip of the black rhinoceros is an adaptation to help browsing.
The black rhinoceros or Diceros bicornisor species overall is classified as critically endangered (even though the south-western black rhinoceros is classified as near threatened). Three subspecies have been declared extinct, including the western black rhinoceros, which was declared extinct by the International Union for Conservation of Nature (IUCN) in 2011.
The black rhinoceros or Diceros bicornisor species was first named Rhinoceros bicornis by Carl Linnaeus in the 10th edition of his Systema naturae in 1758. The name means “double-horned rhinoceros”.
There is some confusion about what exactly Linnaeus conceived under this name as this species was probably based upon the skull of a single-horned Indian rhinoceros (Rhinoceros unicornis), with a second horn artificially added by the collector. Such a skull is known to have existed and Linnaeus even mentioned India as origin of this species.
However he also referred to reports from early travellers about a double-horned rhino in Africa and when it emerged that there is only one, single-horned species of rhino in India, Rhinoceros” bicornis was used to refer to the African rhinos (the white rhino only became recognised in 1812). In 1911 this was formally fixed and the Cape of Good Hope officially declared the type locality of the species.
