All children are sure to know about the cheetah. You would
know that fastest land animal on Earth with the ability to run at speeds of 112
to 120 km/h (70 to 75 mph), accelerating from 0 to over 100 km/h (62 mph) in just
three seconds. The speed and grace of this member of cat family have astonished
humans and the sight of a stop us in our tracks.
Scientists think that about 10,000-12,000 years ago, at
least 99 percent of the world king cheetah population may have died within a
short period, resulting in the population getting as low as one pregnant
female. The main difference between the king cheetah and the normal spotted
cheetah is in the cat pattern. The standard cheetah’s fur coat is usually yellow,
tawny or golden in color with a circular spotted pattern of small black
markings, 0.75 to 1.5 inches in diameter, distributed fairly evenly across its
body. The animal also displays the famous black ‘tear streaks’ down either
cheek.
The king cheetah whose coat is pale cream to yellow has a
distinctive patten of spots that run together to form several (usually three)
thick lack stripes down its back, from the crest of its neck to the top of the
tail.
They also sport dark patch shaped markings (splotches),
irregular in size and shape along their sides and flanks. Their underside is
generally white. The tear tracks on the face are present in the king cheetah as
well.
The reason for this difference was discovered recently to be
a mutation of the gene which causes the spots in cheetahs. The same gene, it
was found, produces the striking dark strips on tabby cats and its mutation
causes the stripes in cats and spots on cheetahs to become blotchy. King
cheetahs are the result of two parents with the same recessive gene coming
together (a reason for its rarity) and may occur side by side with normally
colored litter mates.
However, they have the
same genetic makeup as the common cheetah with little genetic diversification
and problems inherent from inbreeding. The king cheetah, measuring 1.1-1.4
metres in length, 66-85 cm in height up to the shoulders and weighing 40-65kg,
is slightly larger than the common cheetah.
Other rare color
morphs (gradual transformation) of the species include speckles, melanism,
albinism and grey coloration. Most have been reported in Indian cheetahs,
particularly in captive specimens kept for hunting. The king cheetah is found
in Zimbabwe, Botswana and in the northern parts of South Africa’s Transvaal
province. Their natural habitat comprise savannah and open areas such as
plains, wooded areas and grasslands. While cheetahs prefer to chase their prey
on the open plains, king cheetahs can be found in forests, stalking their meal
which is mostly medium and large-sized mammals. Cheetahs hunt during the day, while
king cheetahs hunt mostly at night. Since splotches are better camouflage for
partially lit environment, the coats of the latter are better suited to shady
forests.
