The pronghorn (UK: /ˈprɒŋhɔːrn/, US: /ˈprɔːŋ-/) (Antilocapra americana) is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. Pronghorns have distinct white fur on their rumps, sides, breasts, bellies, and across their throats. Adult males are 1.3–1.5 m (4 ft 3 in – 4 ft 11 in) long from nose to tail, stand 81–104 cm (2 ft 8 in – 3 ft 5 in) high at the shoulder, and weigh 40–65 kg (88–143 lb). The females are the same height as males, but weigh 34–48 kg (75–106 lb). The feet have two hooves, with no dewclaws. Their body temperature is 38 °C (100 °F). The pronghorn is the fastest land mammal in the Western Hemisphere, with running speeds of up to 90 km/h (55 mph). It is the symbol of the American Society of Mammalogists.
