While comparing between various classes of animals, a different unit is used, body length per second for organisms. The fastest organism on earth, relative to body length, is the South Californian mite "Paratarsotomus macropalpis", which has a speed of 322 body lengths per second. The equivalent speed for a human running as fast as this mite would be . This is far in excess of the previous record holder, the Australian tiger beetle, "Cicindela eburneola", the fastest insect in the world relative to body size, which has been recorded at or 171 body lengths per second. The cheetah, the fastest land mammal, scores at only 16 body lengths per second while Anna's hummingbird has the highest known length-specific velocity attained by any vertebrate

The cheetah is the fastest land animal. It was called the "felid version of the greyhound", as both have similar morphology and the ability to reach tremendous speeds in a shorter time than other mammals.

It is the fastest land animal. Cheetahs can reach speeds of in short bursts, but the top end speed of the cheetah is disputed by more recent measurements. The average speed of a cheetah while hunting is about .

The mite has been recorded at a speed of 322 body lengths per second (). This is far in excess of the previous record holder, the Australian tiger beetle "Cicindela eburneola", the fastest insect in the world relative to body size, which has been recorded at or 171 body lengths per second. The cheetah, the fastest land animal, which has been clocked at a peak of , scores at only 16 body lengths per second.

Some of the larger animals roaming the grasslands include pronghorns, black-tailed jackrabbits (hares), Gunnison's prairie dogs, coyotes, bobcats and foxes. Pronghorns, the fastest land animals in North America, are capable of sprints. They are the second fastest land animal on Earth. The blood vessels in the huge, thin-walled ears of the jackrabbits act as heat exchangers. These hares are known for their bursts of speed, long leaps, and zigzag routes, all of which protect them from being eaten by golden eagles and other predators. The prairie dogs live in large colonies or "towns", near which many other species find food and shelter. Coyotes dine largely on rodents but also eat fruits, reptiles, insects, small mammals, birds, and carrion.

In April 2014, the South Californian mite "Paratarsotomus macropalpis" has been recorded as the world's fastest land animal relative to body length, at a speed of 322 body lengths per second. Besides the unusually great speed of the mites, the researchers were surprised to find the mites running at such speeds on concrete at temperatures up to , which is significant because this temperature is well above the lethal limit for the majority of animal species. In addition, the mites are able to stop and change direction very quickly.

The pronghorn are North America's fastest land animal, capable of speeds up to , run free across the upland sagebrush at the east side. Bighorn sheep prefer the rocky cliffs of the refuge's west side. Numerous shallow lakes, grassy spring fed meadows attract the greatest variety of species.

Paratarsotomus macropalpis is a species of mite belonging to the family Anystidae. The mite is endemic to Southern California and is usually observed darting amongst sidewalks and in rocky areas. Earlier classified as belonging to genus "Tarsotomus", it was reclassified in 1999, along with four other species, to genus "Paratarsotomus". It is quite small—0.7 mm—but has been recorded as the world's fastest land animal relative to body length.
