The members of the rhino family are characterized by their large size (they are some of the largest remaining megafauna, with all species being able to reach a ton or more of weight); as well as a herbivorous diet; a thick protective skin, 1.5–5 cm thick, formed by collagen layers positioned in a truss structure; relatively small brains for mammals of this size (400–600 g); and a big horn. They usually eat hardwood material, although their ability to ferment food in their posterior intestine allows them to subsist on more fibrous plant matter if necessary. Unlike other perissodactyls, the two African rhino species do not have teeth in the front of the mouth, but rely on the lips to harvest food.

Rhinos are killed by humans for their horns, which are bought and sold on the black market and which are used by some crops for traditional ornamental or medicinal purposes. East Asia, specifically Vietnam, is the largest market for rhino horns. By weight, rhino horns cost as much as gold on the black market. People grind the horns and then consume them believing that dust has therapeutic properties. The horns are made of keratin, the same type of protein that makes up the hair and nails. Both African species and Sumatran rhinoceros have two horns, while the Indian and Javan rhinoceros have a single horn.
