It is hard to imagine a more elegant and agile creature than the common impala (Aepyceros melampus melampus). Long legs give it the ability to sprint up to 55 mph, jump over an obstacles more than ten feet high, and leap a distance of 33 feet.
We often encounter groups of these gregarious creatures in East Africa. They are easily identified due to their medium size, reddish-brown coat, lyre-shaped horns, and black markings on the hind-quarters. Imagine the black marks on the rump advertising the letter "M." See it? Don't blink. That's an iMpala!
Something else that might be of interest: note the black marking on the "ankles" (metatarsals) of the impala's rear legs? Those are scent glands. The impala is the only member of the antelope family that has these features. Some think that the impala leaves a "chemical trail" for others to follow in a chase! What's more, that trail has the smell of cheese! Cheese chase? Of course!
