The Sitatunga or marshbuck (Tragelaphus spekii) is a swamp-dwelling antelope found throughout Central Africa, centering on the Democratic Republic of the Congo, Cameroon and parts of Southern Sudan as well as in Ghana, Botswana, Zambia, Gabon, Tanzania, Uganda and Kenya. Sitatunga live in papyrus swamps and are very good swimmers. They may take to the water to evade predators such as leopards or African wild dogs, lying submerged in pools with only their nostrils above the surface. They are crepuscular although they are also somewhat active at night and day. Sitatunga can be solitary; females tend to stick in herds while males become mostly solitary after mating. This medium sized antelope is highly specialised for a semi-aquatic lifestyle, spending the greater part of its life in papyrus swamps of Africa. The most obvious physical adaptation to their marshy environment is their long, splayed hooves, which enable the animal to stand and walk on mud and floating islands of vegetation without sinking. This unusual animal has a slim face, slender neck and legs, and hindquarters that are higher than the forequarters, giving the Sitatunga its peculiar hunched appearance. The shaggy, water-resistant coat varies in colour.
