, Aepyceros melampus, found in the savannah and bush country of E and S Africa. It is the antelope most commonly depicted in illustrations and in motion pictures. It is about 3 ft (90 cm) high at the shoulder, with a coat of rich, reddish brown, shading to whitish on the underparts. The horns, borne only by the male, are long and curved in the shape of a lyre. Impalas are the most powerful jumpers of all antelopes; they can leap 10 ft (3 m) into the air and travel 30 ft (9 m) in a single bound. Impalas live in herds, sometimes numbering several hundred individuals; they feed on grasses and shrubs and always stay fairly near water. They are often found in association with herds of other animals, such as zebras and gnus, and are still fairly numerous over most of their range.

Impala

 

(Aepyceros melampus), an artiodactyl mammal of the family Bovidae. The body length is 1.1–1.8 m; the height at the shoulder is 77–100 cm; the tail length is 25–40 cm; and the weight is 40–90 kg. The males have lyrate horns reaching 75 mm in length; the females are hornless. The coloration is brownish red above. The underside of the body and the tail are white. The impala is found in the savannas and cleared forest areas of central and southern Africa. The animal lives in groups of 20 to 25 individuals.

In southern Africa, impala (Aepyceros melampus melampus) and blesbok (Damaliscus dorcas phillipsi) show parallel adaptations, with impala more closely mirroring caribou, and those adaptations of blesbok resembling muskoxen.
Caribou (Rangifer tarandus) and muskoxen (Ovibos moschatus) in the Arctic show adaptations to their environment similar to those of impala (Aepyceros melampus melampus) and blesbok (Damaliscus dorcus phillipsi) in southern Africa (Fig.

Other species are more characteristic of the typical grassy savannahs: among them are the impala (Aepyceros melampus), the two species of gnu (Connochaetes taurinus and C.
The study assessed flight behavioural responses of impala (Aepyceros melampus) and kudu (Tragelaphus strepsiceros) to human disturbance and compared densities of common large herbivores across Gonarezhou National Park (non- consumptive land use) and the adjacent Malipati Safari Area (consumptive land use) in southeast Zimbabwe.
Specifically, our study objectives were twofold: (i) to compare the impala (Aepyceros melampus) and kudu (Tragelaphus strepsiceros) vigilance behaviour between southern Gonarezhou and Malipati, and (ii) to determine and compare common large herbivore densities in southern Gonarezhou and Malipati.
