Description
Photographed at the San Diego Wild Animal ParkBlack Rhino
Rhinoceroses get their name from their most famous feature: their horns. The word rhinoceros comes from the Greek rhino (nose) and ceros (horn). For ages, rhino horn has been used to treat illnesses, especially fevers. Yet like our fingernails and hair, rhino horn is made of keratin and has no healing properties. In some countries, rhinos are being dehorned, a process that removes the valuable horn but leaves the animal alive and well. This prevents poachers from killing rhinos for the money their horns would bring.
The five types of rhinos are the Sumatran, Javan, black, white, and Indian. Javan rhinos and Indian rhinos have only one horn, while Sumatran rhinos, black rhinos, and white rhinos have two. What they all have in common are large heads, broad chests, thick legs, poor eyesight, excellent hearing, and a fondness for rolling in the mud. Because they are very nearsighted, they often charge when they are startled. This has given them an undeserved reputation for having a bad temper. All rhinos are herbivores, eating grasses or leaves, depending on the species.
