The genus Strepsiceros is represented by the true or great kudu (S.
Among the varieties are the greater and lesser kudu (both rather rare); the duiker, gemsbuck, hartebeest, gerenuk (the most common - it has long thin legs and a camel-like neck); klipspringer, found on the high plateaus as well as in the lower districts; and the dik-dik, the smallest of the antelopes, its weight rarely exceeding so lb, common in the low countries and the foothills.
In stature they range from the size of a hare to that of a rhinoceros; and their horns vary in size and shape from the small and simple spikes of the oribi and duiker antlers to the enormous and variously shaped structures borne respectively by buffaloes, wild sheep and kudu and other large antelopes.
The antelopes include the beisa oryx, fairly common and widely distributed; the greater and lesser kudu (the greater kudu is not found on the Ogaden plateau); the Somali hartebeest (Bubalis Swaynei), found only in the Haud and Ogo districts; waterbuck, rare except along the Webi Shebeli and the Nogal; the dol or Somali bushbuck; the dibatag or Clarke's gazelle; the giraffe-like gerenuk or Waller's gazelle, very common; the aoul or Soemmering's gazelle, widely distributed; the dero (Gazella Speki); and the small dikdik or sakaro antelope, found in almost every thicket.
The kudu is now the most common of the larger antelopes, the duiker and klipspringer are among the smaller antelopes still existing in large numbers.
