Cheetahs
are, without a doubt, the fastest creatures in the world on land.
(There's probably some wickedly fast creatures in the ocean that we
still don't even know about). Why would a cheetah need to be able
to run so fast? The only animal that comes in a close second to the
Cheetah's amazing speed is its favorite prey, the gazelle. In order
to catch up with a meal that's as swift as the wind, the cheetah
had
to develop the ability to run as fast, or faster than the gazelle,
or face the alternative - starvation. Pretty strong motivation for
practicing their wind sprints.
Cheetahs are Specialized
Cats
Cheetahs are an excellent
example of the effects of natural selection on
creating a super fast, aerodynamic hunting cat. There are several
species of large cats in the world, including leopards, lions, jaguars,
mountain lions, ocelots, and tigers, but none of them can match the
speed of the cheetah. Natural selection works when those creatures
having the best physical ability, body design, and behaviors to adapt
to their environment and survive, where other creatures without those
"cool features" will not survive to pass on their genes to another
generation. There are many other large wild cats who look and behave
very differently from the cheetah, but have adapted to survive in
their environments in other ways. Look at the cool features on the
cheetah that help to make it such an awesome speed demon Click
to see a video of a Cheetah running):
· it has a long,
super streamlined body with long, powerful legs - longer legs mean
fewer strides from point A to point B
· the cheetah's
head is small in proportion to its body (compare it to other large
cats) - part of its aerodynamic styling for less resistance for greater
speed
· the long,
powerful tail helps the cheetah to maintain balance when changing
direction at extremely high speeds
· did
you know that cheetahs can "bark"? They make several different
types of vocalizations, but they don't growl. Listen
to the sound of a Cheetah purring.
Although the Cheetah
is one fast runner, he can only maintain that incredible velocity for
about 200 to 300 yards/274 meters. These high speeds only allow the
cat to overtake its prey within short distances, so cheetahs must still
rely on stealth, sneaking, and the element of surprise to get close
enough to the gazelle before giving chase.

Cheetahs have characteristic dark lines that look like "tears".
It is believed this coloration helps to absorb glaring sunlight
for better vision during the day.
