A gazelle is any of many antelope species in the genus Gazella, or formerly considered to belong to it. Six species are included in two genera, Eudorcas and Nanger, which were formerly considered subgenera. The genus Procapra has also been considered a subgenus of Gazella, and its members are also referred to as gazelles; however they are not dealt with in this article. Gazelles are known as swift animals some are able to run at bursts as high as 60 miles per hour (97 km/h), or run at a sustained speed of 30 miles per hour (48 km/h). Gazelles are mostly found in the deserts, grasslands and savannas of Africa, but they are also found in southwest and central Asia, and the Indian subcontinent. They tend to live in herds and will eat less coarse, easily digestible plants and leaves. Gazelles are rather small antelopes, most standing 23.5 ft (61110 cm) high at the shoulder, and are generally fawn-colored. The gazelle genera are Gazella, Eudorcas and Nanger.
