Facts about the rhinoceros include that the white rhino is the second-largest land animal, with the elephant being the largest. A rhino weighs up to 8,000 pounds and stands up to 6 feet tall. Rhinos live about 35 years in the wild and 40 years in captivity.
There are five species of rhinoceros; two live in Africa and three live in Asia. Their habitat encompasses savannas to dense forests in tropical and subtropical areas. There are white rhinos and black rhinos, although both types are actually gray in color. The main difference between white and black rhinos is the shape of their lips. The black rhino has a pointed upper lip, while the white rhino has a square-shaped lip. The white rhino subsists mainly on grass, for which its square-shaped lips are well-suited, while black rhinos eat leaves and fruit from trees and bushes.
Rhinos live mainly solitary lives and establish their own territories. Males and females engage in courtship during which they may fight. Baby rhinos are born after a gestation period of 14 to 18 months. Although they are able to eat vegetation when they are as young as one week old, they nurse for over a year.
The rhinoceros is one of the most endangered animals in the world as of 2015. Poachers hunt the animals for their horns, as some cultures believe that the powdered rhino horn has a number of curative properties.
