context_page_description: The African rock python is a species of large constrictor snake in the family Pythonidae. The species is native to sub-Saharan Africa. It is one of 11 living species in the genus Python. It has two subspecies. One subspecies is found in Central and Western Africa, and the other subspecies is found in Southern Africa.
  Africa's largest snake and one of the six largest snake species in the world, specimens may approach or exceed 6 m. The southern subspecies is generally smaller than its northern relative. The snake is found in a variety of habitats, from forests to near deserts, although usually near sources of water. The snake becomes dormant during the dry season. The African rock python kills its prey by constriction and often eats animals up to the size of antelope, occasionally even crocodiles. The snake reproduces by egg-laying. Unlike most snakes, the female protects her nest and sometimes even her hatchlings.
  The snake is widely feared, though it very rarely kills humans. Although the snake is not endangered, it does face threats from habitat reduction and hunting. Some cultures in Sub-Saharan Africa eat this snake as delicacy which might generally be threat to its population.
context_section_description: Africa's largest snake species and one of the world's largest, the typical African rock python adult measures 3 to 3.53 m (9 ft 10 in to 11 ft 7 in) in total length (including tail), with only unusually large specimens likely to exceed 4.8 m (15 ft 9 in). Reports of specimens over 6 m (19 ft 8 in) are considered reliable, although larger specimens have never been confirmed. Weights are reportedly in the range of 44 to 55 kg (97 to 121 lb), per one study adults are expected to weigh only up to 32.2 kg (71 lb). Exceptionally large specimens may weigh 91 kg (201 lb) or more. On average, large adults of African rock pythons are quite heavily built, perhaps more so than most specimens of the somewhat longer reticulated as well as Indian and Burmese pythons and far more so than the Amethystine python, although the species is on average less heavily built than the green anaconda. The African species may be the second heaviest living snake with some authors agreeing that it can exceptionally exceed 90 kg (200 lb). One specimen, reportedly 7 m (23 ft 0 in) in length, was killed by K. H. Kroft in 1958 and was claimed to have had a 1.5 m (4 ft 11 in) juvenile Nile crocodile in its stomach. An even larger specimen considered authentic was shot in The Gambia and measured 7.5 m (24 ft 7 in).
  The snake varies considerably in body size between different areas. In general, it is smaller in highly populated regions, such as in southern Nigeria, only reaching its maximum length in areas such as Sierra Leone, where the human population density is lower. Males are typically smaller than females.
  The African rock python's body is thick and covered with colored blotches, often joining up in a broad, irregular stripe. Body markings vary between brown, olive, chestnut, and yellow, but fade to white on the underside. The head is triangular and is marked on top with a dark brown “spear-head” outlined in buffy yellow. Teeth are many, sharp, and backwardly curved. Under the eye, there is a distinctive triangular marking, the subocular mark. Like all pythons, the scales of the African rock python are small and smooth. Those around the lips possess heat-sensitive pits, which are used to detect warm-blooded prey, even in the dark. Pythons also possess two functioning lungs, unlike more advanced snakes, which have only one, and also have small, visible pelvic spurs, believed to be the vestiges of hind limbs.
  The southern subspecies is distinguished by its smaller size (adults typically about 2.4 to 4.4 m in length), smaller scales on top of the head, and a smaller or absent subocular mark.
