Cheetah The Fastest Animal in The World

The cheetah (Acinonyx jubatus) is a large cat (family Felidae, Felinae subfamily) inhabit most of Africa and parts of the Middle East. This is the only extant member of the genus Acinonyx. Cheetah can run faster than other land animals as soon as 96.5 to 104 km / h (60.0 to 65 mph) in short spray covers a distance of up to 500 m (1,600 ft), and has the ability to accelerate from 0 to over 100 km / h (62 mph) in three seconds.

Cheetah's chest is deep and narrow waist. Fur, short rough cheetah is tan with round black spots measuring from 2 to 3 cm (0.79 to 1.2 inches), affording it some camouflage while hunting. Nowhere under the white, 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 bundle. Cheetah has a small head with high-set eyes. "The sign of tears" running from the corner of his eye black down the side of the nose to its mouth still sun out of the eyes and aid in hunting and seeing long distances. Although you can reach high speeds, its body can not stand long distance running, as more suitable for short bursts of speed.

Adult cheetah weighs 21-72 kg (46-160 lb). Total head and body length is 110-150 cm (43-59 in), while the tail can measure 60-84 cm (24 to 33 in) long. Cheetahs are 66-94 cm (26 to 37 in) tall at the shoulder. Men tend slightly larger than females and have slightly bigger heads, but there is no great variation in cheetah sizes and it is hard to say, men and women separately by appearance alone. Compared with similar-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (the average is around 90 cm (35 in) tall) and so appear more slender.

Some cheetahs have large rare fur pattern mutation, acne, freckles join. Known as the "king cheetah," they never considered a separate subspecies but in reality African cheetah, unusual patterns of their fur is the result of a single recessive gene. "The king cheetah" just look at some wild times, but was raised in captivity.

Cheetah paws have semi-retractable claws (known only in three other cat species: fishing cat, flat-headed cat and the Iriomote cat), offering extra grip in its high-speed chase. Cheetah claws ligament structure is similar to other cats, but just do not have the shroud of skin and fur present in other varieties, and therefore, with the exception of the dewclaw, the claw is visible. Dewclaw much shorter and straighter than with other cats.

Adaptations that enable the cheetah to run as fast as it does not include large nostrils that allow for increased oxygen intake, and enlarged heart and lungs that work together to circulate oxygen efficiently. For special catch, respiration increased speed 60-150 breaths per minute. While running, in addition to having good traction due to its semi-retractable claws, the cheetah uses its tail as a rudder as recommended by the steering [citation needed] In order to make sharp turns, necessary to outflank prey animals that often make such turns to escape.

Unlike a true big cats Pantherinae subfamily, the cheetah can snore like a breath, but can not roar. In contrast, the big cats can roar but can not purr, except when breathed. Cheetah is still considered by some to be the smallest of the big cats. Although often mistaken for leopards, cheetah does have special features, such as the long "tear-streak" lines that run from the corners of the eyes to its mouth, and places that are not "roses". Thinner body frame of the cheetah is also very different from leopards.

Cheetah is a vulnerable species. Of all the big cats, it is the most able to adapt to the new environment. That always proved difficult to breed in captivity, although recently a few zoos have been successful this. After much hunted for its fur, the cheetah now suffers more from the loss of good habitat and prey.
Cheetah was previously considered to be very primitive in between cat and has grown to about 18 million years ago. However, a new study shows that recent ancestor of all 40 existing species of cat living is higher than about 11 million years ago. The same study showed that the cheetah, while highly derived morphological, not of very ancient lineage, having separated from the nearest relatives live (Puma concolor, cougar, and Puma yaguarondi, the jaguarundi) around five million years ago.These felids have not change bearable since they first appeared in the fossil record.
