Animal Name: Sitatunga.

The  Tragelaphus spekii, sometimes called the marshbuck is a Swampdwelling medium-sized Antelope found throughout central Africa, centering on the Democratic Republic of the Congo, the Republic of the Congo, Cameroon, Southern Sudan, Equatorial Guinea, Burundi, Ghana, Botswana, Rwanda, Zambia, Gabon, Central African Republic, Tanzania, Uganda, Kenya. The sitatunga is mostly confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps.  The species was Scientific description by the English explorer John Hanning Speke in 1863. Speke first observed the sitatunga at a lake named Little Windermere (now Lake Lwelo, located in Kagera Region Tanzania. In his book Journal of the Discovery of the Source of the Nile, Speke called the animal nzoe (Kiswahili language name for the animal) or water-boc (due to its resemblance to the Waterbuck. The scientific name has often been misstated as T. spekei, and either Speke or Sclater is referred to as the Binomial nomenclature.

The sitatunga is a medium-sized antelope. It is Sexually dimorphic, with males considerably larger than females. The head-and-body length is typically between 136–177 cm (54–70 in) in males and 104–146 cm (41–57 in) in females. 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 tail is 14–37 cm (5.5–14.6 in) long. The saucer-shaped ears are 11–17 cm (4.3–6.7 in) long. Only the males possess horns; these are spiral in shape, have one or two twists and are 45–92 cm (18–36 in) long. The sitatunga is almost indistinguishable from the nyala, except in Pelage and Spoor (animal). Speke pointed out that, though "closely allied" to the waterbuck, the sitatunga lacks stripes and is spotted instead. The  color varies geographically, but, in general, is a Rufous red in juveniles and chestnut in females. There are white facial markings, as well as several stripes and spots all over, though they are only faintly visible. White patches can be seen on the throat, near the head and the chest.  A pair of Inguinal lymph nodes. The coats of males darken with age, becoming gray to dark brown. Males develop a rough and scraggy mane, usually  brown in colour, and a white dorsal stripe. There is a Chevron (anatomy) between the eyes of the males.
