A Rhinoceros is an odd-toed hoofed mammal of the family Rhinocerotidae. The one-horned Indian rhinoceros (Rhinoceros unicornis) is up to two meters 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 meters 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. They are solitary and vegetarian, with poor eyesight but excellent hearing and smell. Research Rhinoceros More pictures of Rhinoceros
