Namibia's endangered species include Wild Dog, Black Rhino, Oribi and Puku. The Puku antelope is limited to about 100 individuals along the Chobe River in Botswana and the Linyati marshes in Namibia. The Black and White Rhino have suffered the most from poaching and are on the verge of extinction. If there had been no moves to save them in the last 20 years they probably would have disappeared form the wild altogether. Although both species occur naturally in Namibia, today you will find in many of the reserves that they have been reintroduced. The country also has the largest population in southern Africa of cheetah not contained within National Parks. There are over twenty species of antelope in Namibia ranging from largest, the Eland, to smallest, the Damara dik-dik. The Gemsbok, a striking antelope with long symmetrical horns and distinctive black and white markings is featured on the Namibian coat of arms. Namibia also harbours a wealth of small mammals including Mongoose, Jackal as well as the less common Antbear and Honey Badger, these are not often seen as they are solitary and nocturnal.
