The impala is a medium-sized species of antelope. It stands about three feet tall at the shoulder and weighs over 110 pounds. Its coat is dark above, blending into pale tan below with distinctive black stripe bordering a white patch on its rump. The male has very large lyre-shaped horns and the female has no horns. Like wildebeest, impalas form herds sometimes numbering in the thousands. When impalas in a herd are ambushed, they leap out in all directions, confusing predators with a "starburst" effect.
