The sitatunga or marshbuck (Tragelaphus spekii) is a swamp-dwelling antelope found throughout central Africa, centering on the Democratic Republic of the Congo, Cameroon, parts of Southern Sudan, Ghana, Botswana, Zambia, Gabon, Tanzania, Uganda and Kenya. The species was first described by the English explorer John Hanning Speke in 1863. The sitatunga is a medium-sized antelope. Males reach approximately 81–116 cm (32–46 in) at the shoulder, while females reach 72–90 cm (28–35 in). Males typically weigh 76–119 kg (168–262 lb), while females weigh 24–57 kg (53–126 lb). The sitatunga has a shaggy, water-resistant coat which varies in colour. The body and feet of this antelope are specially adapted to its swampy habitat. Only the males possess horns; these are spiral in shape, have one or two twists and are 45–92 cm (18–36 in) long.
