Tragelaphus spekei Shoulder height 85–90cm. Weight 105–115kg.
The semi-aquatic antelope is a widespread but infrequently observed inhabitant of west and central African papyrus swamps from the Okavango in Botswana to the Sudd in Sudan. In Zambia sitatunga are very widespread. Good populations are found in Bangweulu, the Busanga Swamps, Sumbu and Kasanka.

Because of its preferred habitat, the sitatunga is very elusive and seldom seen, even in areas where it is relatively common. They are also less easy to hunt/poach than many other species, although they are exceedingly vulnerable to habitat destruction. Kasanka National Park's tree hide is commended, at least to the more agile of visitors, as one of Africa's very best places to see these antelope. It provides a superb vantage point above a small section of papyrus swamp, and sightings are virtually guaranteed in the early morning or late afternoon. Sitatunga are noted for an ability to submerse themselves completely, with just their nostrils showing, when pursued by a predator.
