Neither graceful nor beautiful, warthogs are nonetheless remarkable animals. They are found in most of Africa south of the Sahara and are widely distributed in East Africa. They are the only pigs able to live in areas without water for several months of the year. By tolerating a higher-than-normal body temperature, the warthog is perhaps able to conserve moisture inside its body that might otherwise be used for cooling. (Camels and desert gazelles have developed a similar mechanism for survival in hot, arid environments. The warthog has poor vision (though better than most other African wild pigs), but its senses of smell and hearing are good.
When alarmed, the warthog grunts or snorts, lowers its mane, flattens its ears and bolts for underground cover.
