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.
The scientific name of the pronghorn is Antilocapra americana. The pronghorn is the sole extant member of the family Antilocapridae. This species was first described by American ornithologist George Ord in 1815.
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 (32 - 41 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, being built for maximum predator evasion through running. The top speed is very hard to measure accurately and varies between individuals; it can run 35 mph for 4 mi (56 km/h for 6 km), 42 mph for 1 mi (67 km/h for 1.6 km), and 55 mph for 0.5 mi (88.5 km/h for 0.8 km). It is often cited as the second-fastest land animal, second only to the cheetah.
