The 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 ...
A rhinoceros (/ r aɪ ˈ n ɒ s ər ə s / ry-NOSS-ə-rəss; from Ancient Greek ῥινόκερως (rhinókerōs) ' nose-horned '; from ῥίς (rhis) ' nose ' and κέρας (kéras) ' horn '; [1] pl.: rhinoceros or rhinoceroses), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates (perissodactyls) in the family ...

The western black rhino emerged about seven to eight million years ago. It was a sub-species of the black rhino. For much of the 20th century, its population was the highest out of all of the rhino species, at almost 850,000 individuals. There was a 96% population decline in black rhinos, including the western black rhino, between 1970 and 1992.
It also includes the big five (lion, leopards, elephants, rhinos and Cape buffaloes). Lewa holds over 12% of Kenya's eastern black rhinoceros population and the largest single population of Grevy's zebras in the world (approximately 350 individuals). Lewa has its own education program that helps develop schools and students.
Eastern black rhinos in general are currently listed as threatened under the Conservation Status for a number of factors, but mainly due to illegal poaching. The 90% decline in their population is a hazard as mortality rates increase, as is consistent emigration (Primack, 2002).
It is a species of rhinoceros, native to Eastern Africa and Southern Africa, including Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia, and Zimbabwe. Although the species is referred to as black, its colours vary from brown to grey. It is the only extant species of the genus Diceros.
The north-eastern black rhinoceros (Diceros bicornis brucii) is an extinct subspecies of the black rhinoceros (Diceros bicornis) that was native to central Sudan, parts of Ethiopia, Djibouti, and Somalia. Its Somalian range was the last to be eradicated, the subspecies becoming extinct sometime in the early 20th century. [1] [2]
