Cheetah

The cheetah is an atypical member of the cat family Felidae that is unique in its speed, while lacking climbing abilities. Therefore it is placed in its own genus, Acinonyx. It is the fastest land animal, reaching speeds between 112 and 120 km/h (70 and 75 mph) in short bursts covering distances up to 460 m (1,500 ft), and has the ability to accelerate from 0 to 110 km/h (68 mph) in three seconds, faster than most supercats.The cheetah's chest is deep and its waist is narrow. The coarse, short fur of the cheetah is tan with round black spots measuring from 2 to 3 cm (0.79 to 1.2 in) across, affording it some camouflage while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white tuft. The cheetah has a small head with high-set eyes. Black "tear marks" run from the corner of its eyes down the sides of the nose to its mouth to keep sunlight out of its eyes and to aid in hunting and seeing long distances. Although it can reach high speeds, its body cannot stand long distance running. It is a sprinter.The adult cheetah weighs from 40 to 65 kg (88 to 140 lb). Its total body length is from 115 to 135 cm (45 to 53 in), while the tail can measure up to 84 cm (33 in) in length. Males tend to be slightly larger than females and have slightly bigger heads, but there is not a great variation in cheetah sizes and it is difficult to tell males and females apart by appearance alone. Compared to a similarly-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (it averages about 90 cm (35 in tall) and so it appears more streamlined. Some cheetahs also have a rare fur pattern mutation: cheetahs with larger, blotchy, merged spots are known as 'king cheetahs'. It was once thought to be a separate subspecies, but it is merely a mutation of the African cheetah. The 'king cheetah' has only been seen in the wild a handful of times, but it has been bred in captivity.
