The black rhino weighs 800 - 1400 kg (1760 - 3080 lb). Its height varies from 1.3 - 1.8 m (4.3 - 5.9'). The black rhino has 2 horns. Its skin is dark yellow-brown to dark brown or dark gray. The black rhino occurs in a wide variety of habitats, from desert areas in Namibia to wetter forested areas in the highlands of Kenya, to savannas and bushveld areas where the highest densities of black rhino occur. The black rhino is a browser. It prefers leaves, twigs and branches from small acacia?s and other woody shrubs and small trees as well as herbs and legumes. When the weather is hot, the black rhino drinks water daily and must be within walking distance of water. In cooler temperatures it can go without drinking water for up to 5 days if its food is moist. The black rhino?s eyesight is poor, but its hearing is good. Its sense of smell is well developed and is probably the most important of its senses.  

Although its belligerence has been exaggerated, the black rhino is unpredictable and can be a dangerous animal, sometimes charging a disturbing sound or smell. Black rhinos are predominantly solitary, the most commonly observed groups being lone males or adult females with young. Black rhinos that share a part or all or their range exhibit a familiarity with one another instead of the aggression that they exhibit to total strangers. Although at times several bulls may court a female simultaneously without apparent antagonism, serious fights and frequent deaths result from conflicts between males over estrous females. A premating bond develops between the bull and the cow, and the pair remain together during resting and feeding. They sleep in contact with each other.

  The black rhino was formerly found in suitable habitat over most of Africa south of the Sahara, from southwestern Angola across the Cape Province up to East Africa and north, avoiding the Congo Basin and its rain forests, to Somalia and southwestern Ethiopia, then westward along a strip between the Sahara and the Congo and Nigerian forests to the region of Lake Chad. The black rhino population suffered an enormous reduction from a probable several hundred thousand at the start of the 20th century to less than 2,500 by the early 1990s. However, since 1995, black rhino numbers at a continental level have started increasing again. Hunting and clearance of land for settlement and agriculture were the major reasons for the decline of black rhino populations in the 20th century. The situation facing the black rhino is still critical. The demand for rhino horn from Asia (for traditional medicines) and from the Middle East (for dagger handles) persists, and the threat of a return to large-scale poaching is still present.
