Rhinoceroses

The rhinoceros (commonly called rhino for short; plural can be either rhinoceros or rhinoceroses) is any of five surviving species of odd-toed ungulates in the family Rhinocerotidae. All five species are native to Africa or Asia. Rhinoceros is also one of the genera in this family.

The family is characterised by: large size (one of the few remaining megafauna surviving today) with all of the species capable of reaching one tonne or more in weight; a horn on the centre of the forehead (sometimes with a second one behind it); herbivorous diet; and a thick protective skin, 1.5-5 cm thick, formed from layers of collagen positioned in a lattice structure. Rhinoceros also have acute hearing and sense of smell, but poor eyesight over any distance. Most rhinoceros live to be about 50 years old or more. A male rhinoceros is called a bull, a female a cow, and the young a calf; a group of rhinoceros is called a "crash".

Rhinoceros, despite being herbivorous, are dangerous animals. In India and Nepal, the Indian rhinos cause the greatest number of human deaths each year, surpassing those caused by tigers and leopards. They have been known to charge even working elephants carrying tourists through the jungles.

Rhinoceros horn

The most obvious distinguishing characteric of the rhinos is a large horn above the nose. The word rhinoceros comes from the Greek words rhino (nose) and keros (horn). Rhinoceros horns, unlike those of other horned mammals, consist of keratin.

Rhinoceros horns are used in traditional Asian medicine, and for dagger handles in Yemen and Oman. None of the five rhinoceros species have secure futures; the White Rhinoceros is perhaps the least endangered, the Javan Rhinoceros survives in only tiny numbers (estimated at 60 animals in 2002) and is one of the two or three most endangered large mammals anywhere in the world.

Rhino protection campaigns began in the 1970s, but rhino populations have continued to decline dramatically. Trade in rhinoceros parts is forbidden under the CITES agreements, but poaching is a severe threat to all rhinoceros species.

Legends

There are a number of legends about rhinoceroses stamping out fire. The story seems to have been common in Malaysia and Burma.

This type of rhinoceros even had a special name in Malay, badak api, where badak means rhinoceros and api means fire. The animal would come when a fire is lit in the forest and stamp it out.

Whether or not there is any truth to this has not yet been proven, as there has been no documented sighting of this phenomenon in recent history. This lack of evidence may stem from the fact that rhinoceros sightings overall in South East Asia have become very rare, largely due to widespread illegal poaching of the critically endangered animal.

The idea of rhinos stamping out fire featured prominently in the movie The Gods Must Be Crazy and also in an episode of The Simpsons.

Also in James and the Giant Peach by Roald Dahl, James' parents are swallowed by a rhinoceros but rhinoceros are, in fact, herbivores.

Albrecht Dürer created a famous woodcut of a rhinoceros in 1515, without ever seeing the animal depicted. As a result, Dürer's Rhinoceros is rather inaccurate.
