“The Sumatran Rhinoceros (Dicerorhinus sumatrensis) is a member of the family Rhinocerotidae and one of five extant rhinoceroses. It is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, standing about 120–145 centimetres (3.9–4.76 ft) high at the shoulder, with a body length of 250 centimetres (8.2 ft) and weight of 500–800 kilograms (1,100–1,800 lb). Like the African species, it has two horns; the larger is the nasal horn, typically 15–25 centimetres (5.9–9.8 in), while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Sumatran Rhino's body”. – Wikipedia
