CHEETAH

n.

Slender, long-legged cat ( Acinonyx jubatus ) that lives on open plains of southern, central, and eastern Africa, and in the Middle East, where it is all but extinct.

The fastest land animal in the world over short distances, it can reach a speed as great as 71 mph (114 kph). Its claws differ from those of other cats in being only partly retractable and in lacking protective sheaths. Like cats in the genus Felis , cheetahs purr rather than roar. The cheetah grows to about 55 in. (140 cm) long, excluding the 29–31-in. (75–80-cm) tail, and weighs 75–119 lbs (34–54 kg). The adult's coarse fur is sandy yellow above, white below, and covered with small black spots; a black streak runs down the face from the corner of each eye. The cheetah hunts by day, alone or in small groups.
