Impala is an African antelope known for its swift, graceful jumping and running. Impalas may travel 30 feet (9 meters) in a leap and run 50 miles (80 kilometers) per hour. They stand from 33 to 37 inches (84 to 94 centimeters) high at the shoulder and weigh from 100 to 180 pounds (45 to 82 kilograms). Their glossy coats are mostly reddish-brown on the top and sides, and white on the tail and underparts. The males have lyre-shaped horns up to 3 feet (90 centimeters) long.
The strongest males lead harem herds, which consist of females and young. The other males stay together in bachelor herds or live alone. Impalas live in lightly wooded areas from Kenya and Uganda to South Africa. They eat fruit, grass, and leaves. Their enemies include leopards, lions, and wild African hunting dogs.
