REPORT TEXT - CHEETAH

      Cheetah (Acinonyx jubatus) is a large-sized feline that lives in the most of Africa. It is also the fastest thing on Earth. As far as is known, the speed of a cheetah can reach 112 to 120 km/h (70 to 75 mph). It also has the ability to accelerate from 0 to 100 km/h (62 mph) in 3 seconds. AMAZING!
     The cheetah has unusually low genetic variability. This is accompanied by a very low sperm count, motility, and deformed flagella. Skin grafts between unrelated cheetahs illustrate the former point in that there is no rejection of the donor skin. It is thought that the species went through a prolonged period of inbreeding following a genetic bottleneck during the last ice age. This suggests that genetic monomorphism didn't prevent  a cheetah from flourishing across 2 continents for thousands of years.
        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 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" running from the corner of its eyes down the sides of the nose to its mouth keep sunlight out of its eyes and aid in hunting and seeing long distances. Although it can reach high speeds, its body cannot stand long distance running, because it is more suited to short bursts of speed.
        The adult cheetah weighs from 21 to 72 kg. Its total head-and-body length is from 110 to 150 cm, while the tail can measure 60 to 84 cm  in length. Cheetahs are 66 to 94 cm tall at the shoulder. 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 tall) and so it appears more streamlined..
