Skin transversely ridged and beset by wart-like spiniferous papillae.
The fauna includes the elephant, rhinoceros, buffalo, giraffe, lion, leopard, cheetah, roan-antelope, hartebeeste, kudu and many other kinds of antelope, wart-hog, hares, quail, partridge, jungle-fowl, bustard and guinea-fowl.
Mole-rats are easily recognized by the peculiarly flattened head, in which the minute eyes are covered with skin, the wart-like ears, and rudimentary tail; they make burrows in sandy soil, and feed on bulbs and roots.
Other animals fairly numerous are the spotted hyena, long-eared fox, jackal, aard wolf, red lynx, wild cat, wild dog and wart hog.
In the African wart-hogs (Phacochoerus), which take their name from the large warty lobes projecting from each side of the face, the teeth are remarkably modified.
