'''Rhinoceros''' {{IPAc-en|r|aɪ|ˈ|n|ɒ|s|ər|ə|s}}, eften abbreviatit as '''rhino''', is a group o five [[Extant taxon|extant]] species o [[odd-taed ungulate]]s in the [[faimily (biology)|faimily]] '''Rhinocerotidae'''. Twa o these species are native tae [[Africae]] an three tae [[Soothern Asie]].

Members o the rhinoceros faimily are characterized bi thair muckle size (thay are some o the mucklest remainin [[megafauna]], wi aw o the species able tae reach ane [[tonne]] or mair in wicht); as well as bi an [[herbivore|herbivorous]] diet; a thick pertective skin, 1.5–5&nbsp;cm thick, furmed frae layers o [[collagen]] poseetioned in a [[crystal structur|lattice]] structur; relatively smaa brains for mammals this size (400–600&nbsp;g); an a muckle horn. Thay generally eat leafy material, altho thair ability tae ferment fuid in thair [[colon (anatomy)|hindgut]] allaes them tae subsist on mair fibrous plant matter, if necessary. Unlik ither [[perissodactyl]]s, the twa African species o rhinoceros lack teeth at the front o thair muiths, relyin instead on thair pouerfu [[premolar]] an [[molar (tuith)|molar]] teeth tae grind up plant fuid.<ref name=EoM>{{cite book | editor=Macdonald, D. |author= Owen-Smith, Norman | year=1984 | title= The Encyclopedia of Mammals | url=https://archive.org/details/encyclopediaofma00mals_0 | publisher=Facts on File | location=New York | pages= [https://archive.org/details/encyclopediaofma00mals_0/page/490 490]–495|isbn= 0-87196-871-1}}</ref>

Rhinoceros are killed bi humans for thair horns, which are boucht an sauld on the [[black mercat]], an which are uised bi some culturs for ornamental or [[Tradeetional medicine|tradeetional medicinal]] purposes. East Asie, specifically [[Vietnam]], is the mucklest mercat for rhino horns. Rhino horns cost as much as gowd on the black mercat. Fowk grind up the horns an then consume them believin the dust haes therapeutic properties.<ref>[http://www.npr.org/blogs/parallels/2013/05/14/181587969/Vietnams-Appetite-For-Rhino-Horn-Drives-Poaching-In-Africa Vietnam's Appetite For Rhino Horn Drives Poaching In Africa], by Frank Langfitt, 13 May 2013</ref> The horns are made o [[keratin]], the same teep o protein that maks up [[hair]] an [[Nail (anatomy)|fingernails]].<ref>{{cite web |url=http://www.yesmag.bc.ca/Questions/rhino.html |title=What is a rhinoceros horn made of? |publisher=Yesmag.bc.ca |date=9 October 2003 |accessdate=23 September 2010 |archive-date=2011-09-28 |archive-url=https://web.archive.org/web/20110928130701/http://www.yesmag.bc.ca/Questions/rhino.html |url-status=dead }}</ref> Baith African species an the [[Sumatran rhinoceros]] hae twa horns, while the Indian an [[Javan rhinoceros]] hae a single horn.

The [[IUCN Reid Leet]] identifies three o the species as [[creetically endangered]].
