The Southeast African cheetah (Acinonyx jubatus jubatus) is the nominate cheetah subspecies native to East and Southern Africa. The Southern African cheetah lives mainly in the lowland areas and deserts of the Kalahari, the savannahs of Okavango Delta, and the grasslands of the Transvaal region in South Africa. In Namibia, cheetahs are mostly found in farmlands. In India, four cheetahs of the subspecies are living in Kuno National Park in Madhya Pradesh after having been introduced there.
From the early Pleistocene, the earliest African cheetah fossils have been found in the lower beds of the Olduvai Gorge site in northern Tanzania, although cheetah fossils in Southern Africa were found to be 3.5 to 3.0 million years old. The Southeast African cheetah is the second-oldest subspecies.
Cheetahs from Africa and Asia were previously considered as genetically identical with each other. DNA research and analysis started in the early 1990s and showed that the Southern and East African cheetahs are indeed separate subspecies.
The cheetah is a medium-sized cat. An adult male cheetah's total size can measure from 168 to 213 cm (66 to 84 in) and 162 to 200 cm (64 to 79 in) for females. Adult cheetahs are 70 to 90 cm (28 to 35 in) tall at the shoulder. Males are slightly taller than females and have slightly bigger heads with wider incisors and longer mandibles.
Measurements taken of wild cheetahs in Namibia indicate that the females range in head-and-body length from 113 to 140 cm (44 to 55 in) with 59.5 to 73.0 cm (23.4 to 28.7 in) long tails, and weigh between 21.0 and 63.0 kg (46.3 and 138.9 lb); males range in head-and-body length from 113 to 136 cm (44 to 54 in) with 60 to 84 cm (24 to 33 in) long tails, and weigh between 28.5 and 65.0 kg (62.8 and 143.3 lb).
The cheetah has a bright yellow or sometimes a golden coat, and its fur is slightly thicker than that of other subspecies. The white underside is very distinct, especially on the neck and breast, and it has less spotting on its belly. The spots on the face are more pronounced, and as a whole its spots seem more dense than those of most other subspecies. The tear marks are notably thicker at the corners of the mouth, and almost all of them have distinct brown mustache markings. Like the Asiatic cheetah, it is known to have fur behind its tail and have both white and black tips at the end of its tail. However, the cheetah may also have only a black tip at the end of its tail.
In desert areas, such as the Kalahari, cheetahs are somewhat smaller and lighter in weight, with thinner, bright-colored fur, a trait the Northwest African cheetah also has.
