An impala (Aepyceros melampus Greek αιπος, aipos "high" κερος, ceros "horn" + melas "black" pous "foot") is a medium-sized African antelope. The name impala comes from the Zulu language meaning "gazelle". They are found in savannas and thick bushveld in Kenya, Tanzania, Swaziland, Mozambique, northern Namibia, Botswana, Zambia, Zimbabwe, southern Angola, northeastern South Africa and Uganda. Impalas can be found in numbers of up to two million in Africa.
In the past, taxonomists had put impalas in the same tribe as gazelles, kobs and hartebeests. However, it was found that the impala was so different from any of these tribes that it was put in its own tribe, Aepycerotini. This tribe has now been elevated to full subfamily status.
Usually, two subspecies are distinguished, which is supported by mitochondrial DNA analysis:
Impala range between 75 and 95 cm (30 and 37 in) tall. Average mass for a male impala is 40 to 80 kg (88 to 180 lb), while females weigh about 30 to 50 kg (66 to 110 lb). They are normally reddish-brown in color (hence the Afrikaans name of "Rooibok", not to be confused with rhebok), have lighter flanks and white underbellies with a characteristic "M" marking on the rear. Males, referred to as rams, have lyre-shaped horns, which can reach up to 90 centimeters in length. Females, referred to as ewes, have no horns. The black impala, found in very few places in Africa, is an extremely rare type. A recessive gene causes the black colouration in these animals.
