Impala is the most common antelope of the bushveld regions of South Africa. A very graceful, rufous-fawn antelope, with white underparts, measuring approximately 900 mm at the shoulders. Rams weigh around 60 Kg and ewes 40 Kg. A black stripe extends from the top of the rump down the back of each thigh. The lower hind legs have glands beneath tufts of black hair. Only the rams have horns which are lyre-shaped, and reach a length of 700 mm.
The oxpecker stands guard while living and feeding on the rhinoceros, watching for danger. The bird warns the rhinoceros of danger by making loud chirping or hissing noises. The rhinoceros treats the oxpecker as a guest.
The giraffe is the tallest animal in the world, attaining a height of 5.5 m, its incredibly long neck accounting for much of its height. The long neck has resulted in a complex blood circulatory system, which is not yet fully understood by zoologists. Adult males generally reach a height of about 5 m and females about 4.5 m. Big males can weigh a massive 1 200 kilograms while females usually weigh some 800 to 900 kilograms. Their skin color is tan with light brown patches on females and dark brown patches on males. Both males and females have short horns covered in skin.
