The cheetah (Acinonyx jubatus) is a big cat in the subfamily Felinae that inhabits most of Africa and parts of Iran. It is the only extant member of the genus Acinonyx. The cheetah can run as fast as 109.4 to 120.7 km/h (68.0 to 75.0 mph), faster than any other land animal. It covers distances up to 500 m (1,640 ft) in short bursts, and can accelerate from 0 to 96 km/h (0 to 60 mph) in three seconds. (source)
