“Background The white rhinoceros (Ceratotherium simum) belongs to the family Rhinocerotidae (order Perrisodactyla) and is the largest of the five species of rhinoceros and the world’s third largest land mammal after the African and Indian elephants. It has a massive body and large head, and its weight ranges from 1,360 to 3,630 kg. White rhinoceroses are herbivore grazers. They spend about half of the day eating grass and are normally found in the savannah and grassland habitats [1].
