How fast can an antelope




















Did all of your scents diffuse through the balloon? The balloon has tiny pores or openings on its skin. Air diffuses from areas of high pressure inside the balloon into the lower air pressure surrounding the balloon. You are commenting using your WordPress.

The Caprivi Strip in Namibia is a great place to see tsessebe running around. Kruger National Park in South Africa is another option. You can also see them in the Serengeti but sighting them can become mixed up with all the other antelope that live there.

Springbok can be the highlight of any visit to South Africa. You do not need to be on safari to see one. For example, springbok are a highlight of visiting the Cape of Good Hope. Springbok run by making long hops over the savannah.

Each hop can take them many meters and they have specially adapted legs that absorb all the shock. Continue reading the complete springbok story here. Wildebeest have poor eyesight , especially in the dark. They survive lions and leopards by gathering in large herds, where there are lots of eyes and ears sensing for danger. Blue wildebeest run fast and not only when being chased.

Serengeti National Park and Masai Mara are the best destinations for witnessing lots of wildebeest running around. Over a million wildebeest graze in this ecosystem. During the mornings you can see them galloping around purely for fun, their ebullient faces a highlight of any safari.

Although small they have very strong legs that propel them high into the air. They turn sharply and use their stamina to evade predators. Impala are born to run. In fact, speed is their only real defence against predators. These elegant antelopes are very fast at running through trees. They are agile and nimble, so they can comfortably outwit their hunters.

You can view common impala all over East and Southern Africa. For a special safari treat you can search for the endangered black-faced impala in northern Namibia. They are a big meal for predators, with males weighing up to 80 kg.

Pronghorn can sustain blazing speeds for miles, and in a distance, run would easily beat a cheetah without breaking a sweat. Pronghorn can reach top speeds of around 55 mph and can run at a steady clip of 30 mph for over 20 miles! For comparison with the other fastest land animal, cheetahs can reach speeds of over 60 mph but only for sprints of about yards.

Pronghorn could finish a marathon in about 45 minutes, while a human would be working hard to finish a marathon in over two hours. This speed starts at a very young age. Females give birth in the spring to one or two fawns, which stay hidden in the grass until they are old enough to outrun their primary non-human predators of coyotes, bobcats and golden eagles. This happens in just a couple weeks. In fact, a fawn can outrun a human in just a matter of days after being born.

Byers, a scientist who has studied pronghorn for over 20 years and has had to test out these speeds while trying to tag fawns for long-term study. But if a pronghorn can so easily leave every predator on North America in the dust, even at a very young age, just how and why did it get to be this fast? According to Stan Lindstedt, a comparative physiologist at Northern Arizona University, there is no secret trick to pronghorn reaching such incredible speeds. Each antelope consumed between six and ten liters of oxygen a minute, which is five times as much as a typical mammal of similar size would burn--a pound goat, say--and more than four times as much as Carl Lewis would consume if he were shrunk to the size of a pronghorn antelope.

A pronghorn stands about three feet at the shoulder. Compared with the goat, it has bigger lungs with which to absorb oxygen, slightly more blood hemoglobin with which to transport the oxygen from the lungs to the muscles, and slightly bigger and leaner muscles containing a higher concentration of mitochondria--the cellular organelles that burn oxygen to provide power for muscle contraction.

In other words, there are no tricks to the pronghorn antelope. So why are they so amazing at running? After some years of wondering about pronghorn in his researches, Dr. Byers has come up with a compelling theory. Though there is no predator today who can catch a pronghorn at a sprint, this wasn't always the case. Byers says the pronghorn runs this fast because it is chased by the "ghosts of predators past" -- including American cheetahs.

Byers argues that the pronghorn perfected its running prowess well over 10, years ago when the North American continent was still home to swift-footed predators like cheetahs, long-legged hyenas, the giant short-faced bear, huge jaguars and saber-toothed cats, along with the more familiar, albeit slower, coyotes and wolves. Predators were much bigger and much faster back then, and thus forced the pronghorn -- and some similarly built and now extinct cousins -- to evolve to be incredibly fast.
