It is usually known as the common waterbuck. Not many fossils of the waterbuck have been found. Impala, kudu, blue wildebeest, waterbuck and zebra roam the wooded lowveld area. Wildebeest, kudu, eland, impala and waterbuck migrate through the area. The scientific name of the waterbuck is "Kobus ellipsiprymnus". They were classified into two groups&colon; the ellipsen waterbuck group and the defassa waterbuck group. The common waterbuck and the defassa waterbuck are remarkably different in their physical appearances. There are also bushbucks, duikers and waterbuck. The waterbuck exhibits great dependence on water. The waterbuck is of a robust build. Masai giraffe, waterbuck, impala, warthog and hippo are also abundant. The waterbuck is one of the heaviest antelopes. By contrast, the defassa waterbuck inhabits western and central Africa. The common waterbuck is found east of the Eastern African Rift. Internal parasites found in waterbuck include tapeworms, liverflukes, stomachflukes and several helminths.
