HabitatEdit

All five rhinoceros species are native to Africa or Asia. The two species in Africa are the White rhinoceros and the Black rhinoceros. The three species in Asia (including islands of Indonesia) are the Javan rhinoceros, Sumatran rhinoceros, and Indian rhinoceros.

LifeEdit

The rhinoceros is a herbivore. Its favourite food is plants, branches and bushes (if it is a browser species), or grass (if it is a grazer species).

Rhinoceroses have a large horn on the nose. Their horns are not like those of other horned mammals: the rhinoceros' horn is made of keratin packed together very tightly.

The rhinoceroses can weigh up to 2,000 kilograms (4,400 lb) and be up to 375 centimetres (12.30 ft) tall.

Rhinoceros and humansEdit

Only the white rhinoceros is not in critical danger of becoming extinct. They are protected, but hunted mainly by poachers, for their horns. The horns are used in Asian medicine, similar to elephants and tigers, and for dagger handles in Yemen and Oman. Loss of habitat is also a danger to rhinos. Governments have made logging their habitat and poaching illegal.
