The name rhinoceros means ‘nose horn’ and is often shortened to rhino.
There are five different species of rhinoceros, three native to southern Asia and two native to Africa. They are the Black Rhinoceros, White Rhinoceros, Indian Rhinoceros, Javan Rhinoceros and Sumatran Rhinoceros.
All five species of rhinoceros can grow to weigh over 1000 kg (2200 lb).
White rhinoceros are generally considered the second largest land mammal (after the elephant).
Rhinoceros horns are made from a protein called keratin, the same substance that fingernails and hair are made of.
