Rhinos have a massive body and fat and short legs. Each foot has three fingers, hence the imprint characteristic cloverleaf. The skin is thick and gray or brown. In the Asian species, the skin at the beginning of the neck and legs is so wrinkled that it gives the impression of a shield. Rhinos have poor eyesight, but this disadvantage is offset by a subtle sense of smell and excellent hearing.
