Gazelles are known as swift animals. Some are able to run at bursts as high as 100 km/h (60 mph) or run at a sustained speed of 50 km/h (30 mph).[2] Gazelles are found mostly 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 eat fine, easily digestible plants and leaves. One widely familiar gazelle is the African species Thomson's gazelle (Eudorcas thomsoni), which is around 60 to 70 cm (24 to 28 in) in height at the shoulder and is coloured brown and white with a distinguishing black stripe. The males have long, often curved, horns.
