This cat is truly built for speed! Virtually
every part of its body is adapted in some way to help it run faster. Special
paw pads and semi-retractable claws provide great traction. Large nostrils
and lungs provide quick air intake; a large liver, heart and adrenals
also facilitate a rapid physical response. A long, fluid, greyhound-like
body is streamlined over light bones. Small collarbones and vertical shoulder
blades help lengthen the stride. The tail acts as a rudder for quick turning
plus the eye's retinal fovea is of an elongated shape, giving the cheetah
a sharp, wide-angle view of its surroundings. The dark tear marks beneath
each eye may also enhance its visual acuity by minimizing the sun's glare.
The spine works as a spring for the powerful back legs to give the cheetah
added reach for each step. But the great speed is very taxing physiologically.
The top speed, 71
miles per hour (114 kilometers per hour), can usually be maintained
for only 200-300 yards. (274 meters). At that point the cheetah's body
temperature increases from the exertion and rest is mandatory. See
