The black rhinoceros 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 is a browser and not a grazer.

The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
As the black rhinoceros population is extirpated in most of these areas, the status of the latter subspecies is unclear. Some animals of the Kenyan population may belong to it. These black rhinos were examined by Benson and others through the Kenya Wildlife Service and had an article published by the African Journal of Ecology (Benson, 1, 791).
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. [1]
Endangered (EN) – very high risk of extinction in the wild, meets any of criteria A to E for Endangered. Vulnerable (VU) – meets one of the 5 Red List criteria and thus considered to be at high risk of unnatural (human-caused) extinction without further human intervention. Near Threatened (NT) – close to being endangered in the near future.
The south-central black rhinoceros (Diceros bicornis minor), also known as the south-central hook-lipped rhinoceros or the lesser black rhino, is a subspecies of the black rhinoceros. In keeping with the rules of zoological nomenclature, the south-central black rhinoceros should be known as Diceros bicornis keitloa (Smith, 1836), a nomen novum. [3]
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.
If the habitat becomes destroyed, the population will see a decline in their numbers. Activities that cause loss of habitat include pollution, urbanization, and agriculture. Another reason for plants and animals to become endangered is due to the introduction of invasive species. Invasive species invade and exploit a new habitat for its natural ...
