The grey rhebok or grey rhebuck (Pelea capreolus), locally known as the Vaal rhebok or Vaalribbok in Afrikaans, is a species of antelope endemic to South Africa, Zimbabwe, Lesotho and Swaziland.
The grey rhebok is a medium-sized antelope weighing 19-30 kg (42-66 lbs) with a long neck, narrow ears, and straight, sharp horns in the male. The horns are ringed at the base and are around 15-25 cm (5.9-9.8 in) long. Only the males carry the straight horns. The coat is short and dense and coloured in various shades of grey.
Their diet consists of grass and leaves.
Confined to the higher areas of Southern Africa, they typically inhabit grassy, montane habitats – for example, sourveld – usually 1000 metres above sea level, and carry a woolly grey coat to insulate them from the cold. However, they are not strictly limited to this habitat as they can be found in the coastal belt of the Cape, almost at sea level. Only the males carry the straight horns. The coat is short and dense and coloured in various shades of grey.
