An impala is a medium-sized African deer. The name impala comes from the Zulu language. Impalas weigh about 120 pounds, are reddish-brown in color with lighter flanks, and have white underbellies. The male has lyre-shaped horns. Impalas are among the most beautiful and graceful of the antelopes. Impalas are found at grassland and woodland edges, usually very close by water. They are among the dominant species in many savannas. Exceedingly agile, impalas are capable of leaping over thirty feet in a single bound. They are gregarious creatures and are usually found in herds, often a male with many females. They are common throughout Southern Africa. Their food consists of a mixture of grasses and woody species. Issued under authority of the Government of Sierra Leone in 2006, this One Dollar legal tender crown-sized (38.6mm) coin features the Impala on its reverse.
