Sitatunga  (Tragelaphus spekii)

Central and Western Africa (2).

The sitatunga lives in thickly vegetated, muddy swamps and marshes (4), normally among boggy papyrus beds (2). The animal is a good swimmer, but prefers to rest on dry mounds or floating islands in the swamp, trampling the grass into a springy mat (4). They will, however, flee into deep water when threatened, and individuals have been observed almost completely submerged underwater, with only their nostrils above the waterline (2).
