A Rhinoceros is an odd-toed hoofed mammal of the family Rhinocerotidae. The one-horned Indian rhinoceros (Rhinoceros unicornis) is up to two metres high at the shoulder, with a tubercled skin, folded into shield like pieces; the African rhinoceroses are smooth-skinned and two-horned. The African black rhinoceros (Diceros bicornis) is 1.5 metres high, with a prehensile upper lip for feeding on shrubs; the broad-lipped or 'white' rhinoceros (Ceratotherium simum) is actually slate-grey in colour, with a squarish mouth for browsing grass.
Black rhinos are solitary and vegetarian, with poor eyesight but excellent hearing and smell and an aggressive temperament, charging any intruders into their territory. White Rhinos by contrast are gregarious, meeting to share wallowing holes where they cover themselves in mud, and then scrape it off on nearby rubbing posts - often an old broken tree stump.
