'''Rhinoceros''' (Greek: ῥῑνόκερως; ''rhinos'' and κέρας ''keras''; "nose-horn") refers to several large [[pachyderm]]atous [[herbivore|herbivorous]] land mammals of Africa and Asia, which bear one or two nasal horns. Rhinoceros have poor vision but a good sense of smell, and despite their size - which is exceeded only by [[elephant]]s - they can quickly face danger and charge at speeds up to 35 mph.

Five species are in existence today, but severely-reduced in numbers; four species currently are near the brink of extinction as a result of the illegal trade in rhino horns:

The head is large and bears the horns for which it is named. The genera ''Rhinoceros'' have a single, large horn; the remaining species have two, of which the front horn is longer. Lacking a bony core, these horns are made entirely of keratin - the same material found in hair and fingernails - which continue to grow throughout life.
