The average adult female white rhinoceros weighs 1.8 tons, while the average adult male weighs 2.3 tons. In terms of size among land mammals, the rhinoceros is second only to elephants.
The scientific name of the white rhinoceros is Ceratotherium simum. One of five living species of rhinoceros, this species is commonly referred to as the square-lipped rhinoceros. Native to Africa, the giant animals attain their size through an herbivore diet. Their square-shaped lips allow them to tear up large sections of grass for consumption. These lips, combined with short legs and a long head held close to the ground, make white rhinoceros perfect grass grazers.
