Cheetahs are the fastest animals on land. They can reach upto 110 kmph speed in just a few seconds. They are fast, but cannot keep up the speed for too long. Their bodies have evolved for speed, with long legs, small face, slim build, an elongated spine, adapted claws to grip the ground and a long tail for balance. Almost all wild cheetahs roam the open, grassy savannahs and open forests in sub-Saharan Africa. A small population also lives in northeastern Iran.
They are smaller in size than other big cats such as lion, tiger, leopards etc, weighing only about 35-55 kgs. Their bodies grow between 1.1m and 1.4m metres long, plus a tail measuring 65cm to 80cm. They have a pale yellow coat with black dots on the upper parts, and white underbelly. They have a unique black line that curve from the inner corner of each eye to the outer corners of the mouth. This mark is known as the teardrop line and scientists believe that the lines help protect cheetahs' eyes from harsh light and see better.
