The Central African rock python (Python sebae) is a species of large constrictor snake in the family Pythonidae. The species is native to sub-Saharan Africa. It is one of 10 living species in the genus Python.
Africa's largest snake and one of the eight largest snake species in the world (along with the green anaconda, reticulated python, Burmese python, Southern African rock python, Indian python, yellow anaconda and Australian scrub python), specimens may approach or exceed 6 m (20 ft). The southern species is generally smaller than its northern relative but in general, the Central African rock python is regarded as one of the longest species of snake in the world. 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 Central 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 is nonvenomous and 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 consider it a delicacy, which may pose a threat to its population.
The Central African rock python is in the genus Python, large constricting snakes found in the moist tropics of Asia and Africa.
P. sebae was first described by Johann Friedrich Gmelin, a German naturalist, in 1789. [3] Therefore, he is also the taxon author of the species.
The generic name Python is a Greek word referring to the enormous serpent at Delphi slain by Apollo in Greek mythology. The specific name sebae is a latinization of the surname of Dutch zoologist, Albertus Seba. [4] [5] Common name usage varies with the species referred to as the African rock python or simply the rock python.
Africa's largest snake species [6] [7] and one of the world's largest, [4] the Central 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. [8] [9] [10] Weights are reportedly in the range of 55 to 65 kg (121 to 143 lb) or more. [11] Exceptionally large specimens may weigh 91 kg (201 lb) or more. [12] [13] [14] On average, large adults of Central 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 species may be the second heaviest living snake with some authors agreeing that it can exceptionally exceed 90 kg (200 lb). [15] [16] [17] 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. [18] An even larger specimen considered authentic was shot in the Gambia and measured 7.5 m (24 ft 7 in). [9] [10]
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. [9] One individual captured in Cote d'Ivoire was allegedly 9.96 m (32.7 ft) long. [19]
The Central 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. [20] [7] 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. [21] [7] Under the eye, there is a distinctive triangular marking, the subocular mark. [20] Like all pythons, the scales of the African rock python are small and smooth. [7] [22] Those around the lips possess heat-sensitive pits, which are used to detect warm-blooded prey, even in the dark. [21] [22] [23] 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. [22] [23]
The Southern African rock python and the Central African rock python differ in the following ways:
The Central African rock python is found throughout almost the whole of sub-Saharan Africa, [29] from Senegal east to Ethiopia and Somalia and south to Namibia and South Africa. [30] [7] P. sebae ranges across central and western Africa, while P. natalensis has a more eastern and southerly range, from southern Kenya to South Africa. [6]
In 2009, a Central African rock python was found in the Florida Everglades. [31] It is feared to be establishing itself as an invasive species alongside the already-established Burmese python. Feral rock pythons were also noted in the 1990s in the Everglades. [8]
The Central African rock python inhabits a wide range of habitats, including forest, savanna, grassland, semidesert, and rocky areas. It is particularly associated with areas of permanent water, [20] [32] and is found on the edges of swamps, lakes, and rivers. [6] [7] The snake also readily adapts to disturbed habitats, so is often found around human habitation, [29] especially cane fields. [4]
Like all pythons, the Central African rock python is non-venomous and kills by constriction. [21] [23] After gripping the prey, the snake coils around it, tightening its coils every time the victim breathes out. Death is thought to be caused by cardiac arrest rather than by asphyxiation or crushing. [21] The African rock python feeds on a variety of large rodents, monkeys, warthogs, antelopes, vultures, fruit bats, monitor lizards, crocodiles, and more in forest areas, [7] and on rats, poultry, dogs, and goats in suburban areas. It will sometimes take fish as well. [33] Occasionally, it may eat the cubs of big cats such as leopards, lions, and cheetahs, cubs of hyenas, and puppies of wild dogs such as jackals and Cape hunting dogs.[ citation needed ]. However, these encounters are very rare, as the adult cats can easily kill pythons or fend them off. [34] [10] On March 1, 2017, a 3.9-m (12-ft 10-in) African rock python was filmed eating a large adult male spotted hyena weighing 70 kg (150 lb). This encounter suggests that the snake might very well be capable of hunting and killing larger and more dangerous animals than previously thought. [35] The largest ever recorded meal of any snake was when a 4.9m African Rock Python consumed a 59-kg impala. [36]
Reproduction occurs in the spring. [4] Central African rock pythons are oviparious, laying between 20 and 100 hard-shelled, elongated eggs in an old animal burrow, termite mound, or cave. [6] [7] The female shows a surprising level of maternal care, coiling around the eggs, protecting them from predators, and possibly helping to incubate them, until they hatch around 90 days later. [6] [21] [7] The female guards the hatchlings for up to two weeks after they hatch from their eggs to protect them from predators in a manner unusual for snakes in general and pythons in particular. [37]
Hatchlings are between 45 and 60 cm (17.5 and 23.5 in) in length and appear virtually identical to adults, except with more contrasting colors. [4] Individuals may live over 12 years in captivity. [38]
Documented attacks on humans are exceptionally rare, despite the species being common in many regions of Africa, and living in diverse habitats including those with agricultural activity. [29] Few deaths are well-substantiated, with no reports of a human being consumed. [29] Large specimens (which are more common in Western Africa) "would have no difficulty in eating adult humans", [29] though it would have to be a small adult human.
As the mammalian and avian game populations are gradually depleted in the Congo Basin, the proportion of large-bodied snakes offered at rural bushmeat markets increases. Consequently, a large proportion of the human population faces the threat of Armillifer armillatus infections, a python-borne zoonotic disease. [51]
People are often fearful of large pythons and may kill them on sight. [6] [29] The Central African rock python is threatened by hunting for leather in some areas. [52] Consequently, it is listed as a Near threatened species. It is also collected for the pet trade, although it is not generally recommended as a pet due to its large size and unpredictable temperament. [38] Little information is available on levels of international trade in this species.
Some of the Central African rock python's habitats are also known to be under threat. For example, mangrove and rainforest habitats and their snake communities are under serious threat in southeastern Nigeria from habitat destruction and exploration for the oil industry. [52] [53]
The Central African rock python is still relatively common in many regions across Africa, and may adapt to disturbed habitats, [29] provided that food is available. The Central African rock python's population in West Africa has suffered greatly, whilst the Southern African species has fared better. This species is heavily exploited throughout its West African range, particularly for bushmeat and leather, and high rates of decline have been reported within the region. These declines appear to exceed 60% over three generations. However, both subspecies have faced declines in population and consequently it is at high risk of being a threatened species. It is listed on Appendix II of the Convention on International Trade in Endangered Species, meaning international trade in Central African rock pythons should be carefully monitored and controlled, [30] giving wild populations some protection from overcollection for pets and skins. The species is also likely to occur in a number of protected areas, such as the Serengeti National Park in Tanzania, a World Heritage site. [54]
In the Florida Everglades, where the Central African rock python is an invasive species and posing a threat to indigenous wildlife, it has no protected status and is one of the species listed on a hunting program recently authorized by state officials to eradicate non-native reptiles, the others being the Burmese python, reticulated python, green anaconda, and Nile monitor. [55]
Luo people of Kenya living mainly in the area near Lake Victoria generally consider snakes to be evil and believe that sorcerers make them harm people. [56] They express a different attitude towards pythons - such as making them appear in play songs and even worshiping them. The Luo call the Central African rock python ng'ielo in their language, [57] and with the songs containing a phrase ng'ielo jadhogre “python the coiling”, children make a line and imitate a python's motion. [58] [59] [60] When the Luo worship a python, they call her Omieri (or Omweri) a returning python-spirit. The python is then seen as a reincarnation of Omieri, Goddess of Harvest and linked with rain and fertility. [61] [56] One which appeared in 2003 raised international controversy over how she should be treated, with coverage from BBC News through the Daily Nation . [62] [63] [56]
In some parts of eastern Nigeria, particularly in the towns of Idemili in Anambra, the python is revered as a sacred symbol of the deity Eke Idemili. Similarly, in Njaba, the Eke Njaba, a harmless snake regarded as the deity's property, is also held in high esteem. This reverence is so deeply ingrained culturally that even Christians in these areas have not fully renounced the sacredness of the snake, and any harm to the Eke Njaba requires ritual cleansing or even a proper burial when killed, to avoid the deity's wrath.[ citation needed ]
The Pythonidae, commonly known as pythons, are a family of nonvenomous snakes found in Africa, Asia, and Australia. Among its members are some of the largest snakes in the world. Ten genera and 39 species are currently recognized. Being naturally non-venomous, pythons must constrict their prey to induce cardiac arrest prior to consumption. Pythons will typically strike at and bite their prey of choice to gain hold of it; they then must use physical strength to constrict their prey, by coiling their muscular bodies around the animal, effectively suffocating it before swallowing whole. This is in stark contrast to venomous snakes such as the rattlesnake, for example, which delivers a swift, venomous bite but releases, waiting as the prey succumbs to envenomation before being consumed. Collectively, the pythons are well-documented and studied as constrictors, much like other non-venomous snakes, including the boas and even kingsnakes of the New World.
The reticulated python is a python species native to South and Southeast Asia. It is the world's longest snake, and the third heaviest after the green anaconda and Burmese python. It is listed as least concern on the IUCN Red List because of its wide distribution. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets. Due to this, reticulated pythons are one of the most economically important reptiles worldwide.
The ball python, also called the royal python, is a python species native to West and Central Africa, where it lives in grasslands, shrublands and open forests. This nonvenomous constrictor is the smallest of the African pythons, growing to a maximum length of 182 cm (72 in). The name "ball python" refers to its tendency to curl into a ball when stressed or frightened.
The Burmese python is one of the largest species of snakes. It is native to a large area of Southeast Asia and is listed as Vulnerable on the IUCN Red List. Until 2009, it was considered a subspecies of the Indian python, but is now recognized as a distinct species. It is an invasive species in Florida as a result of the pet trade.
Morelia spilota, commonly known as the carpet python, is a large snake of the family Pythonidae found in Australia, New Guinea, Bismarck Archipelago, and the northern Solomon Islands. Many subspecies are recognised; ITIS lists six, the Reptile Database six, and the IUCN eight.
The green anaconda, also known as the giant anaconda, emerald anaconda, common anaconda, common water boa, or southern green anaconda, is a semi-aquatic boa species found in South America and the Caribbean island of Trinidad. It is the largest, heaviest, and second longest snake in the world, after the reticulated python. No subspecies are currently recognized. Like all boas, it is a non-venomous constrictor. The term "anaconda" often refers to this species, though the term could also apply to other members of the genus Eunectes. Fossils of the snake date back to the Late Pleistocene in the Gruta do Urso locality.
The Indian python is a large python species native to tropical and subtropical regions of the Indian subcontinent and Southeast Asia. It is also known by the common names black-tailed python, Indian rock python, and Asian rock python. Although smaller than its close relative the Burmese python, it is still among the largest snakes in the world. It is generally lighter colored than the Burmese python and reaches usually 3 m. Like all pythons, it is nonvenomous.
The spotted python, eastern small-blotched python, or eastern Children's python is a python species found in northern Australia and New Guinea. It is a popular pet among Australian reptile enthusiasts and other reptile enthusiasts abroad due to its small size and even temperament. No subspecies were originally recognized. However, two subspecies were recognized as of 2020; A. m. maculosa and A. m. peninsularis.
Grayia is a genus of snakes, commonly referred to as African water snakes, in the family Colubridae. The genus, which is native to tropical Africa, is the only genus in the colubrid subfamily Grayiinae.
Python is a genus of constricting snakes in the Pythonidae family native to the tropics and subtropics of the Eastern Hemisphere.
The Oenpelli python or Oenpelli rock python is a species of large snake in the family Pythonidae. The species is endemic to the sandstone massif area of the western Arnhem Land region in the Northern Territory of Australia. There are no subspecies that are recognised as being valid. It has been called the rarest python in the world. Two notable characteristics of the species are the unusually large size of its eggs and its ability to change colour. It is the longest snake native to the Northern Territory.
Rock python may refer to:
The yellow anaconda, also known as the Paraguayan anaconda, is a boa species endemic to southern South America. It is one of the largest snakes in the world but smaller than its close relative, the green anaconda. No subspecies are currently recognized. Like all boas and pythons, it is non-venomous and kills its prey by constriction.
Morelia spilota spilota is a subspecies of carpet python, popularly known as the diamond python. It is a medium to large snake, found in coastal areas and adjacent ranges of south-eastern Australia. It is the most southerly occurring python in the world and is found at higher altitudes than any other species of Australian python.
Goldie's tree cobra, also known commonly as the African tree cobra and as Gold's tree cobra, is a species of venomous tree cobra in the family Elapidae. The species is native to Central and Western Africa. This species is one of the two tree cobras in Africa, the other being the black tree cobra. Goldie's tree cobra is one of the most venomous snakes and creatures in Africa.
The forest cobra, also commonly called the black cobra and the black and white-lipped cobra, is a species of highly venomous snake in the family Elapidae. The species is native to Africa, mostly the central and western parts of the continent. It is the largest true cobra species with a record length of 3.2 metres.
Jameson's mamba is a species of highly venomous snake in the family Elapidae. The species is native to equatorial Africa. A member of the mamba genus, Dendroaspis, it is slender with dull green upper parts and cream underparts and generally ranges from 1.5 to 2.2 m in total length. Described by Scottish naturalist Thomas Traill in 1843, it has two recognised subspecies. The nominate subspecies is found in central and western sub-Saharan Africa, and the eastern black-tailed subspecies is found eastern sub-Saharan Africa, mainly western Kenya.
On August 5, 2013, an African rock python killed two boys in Campbellton, New Brunswick, Canada. The boys, brothers Noah and Connor Barthe, aged 4 and 6 respectively, were sleeping in an apartment above their friend's father's pet store. The python – which had been in a specially made enclosure in the apartment – had escaped, crawled through an air duct, and fallen through a ceiling tile above where the boys were sleeping. Following the incident, the python was euthanized. The python's owner was charged with criminal negligence for not preventing the deaths but was found not guilty in a jury trial in November 2016.
The Southern African rock python is a large python species native to Southern Africa inhabiting savanna and woodland. It was first described by Andrew Smith in 1833. Growing a length of more than 5 m (16 ft), this is one of the largest snakes in the world.
