Der Gefleckte Python oder Children-Python (Antaresia childreni) ist eine Schlangenart aus der Familie der Pythons (Pythonidae). Das Artepitheton childreni wurde zu Ehren des britischen Zoologen, Chemikers und Mineralogen John George Children vergeben.
Der gefleckte Python ist eine relativ kleine Pythonart mit einer Körperlänge von durchschnittlich etwa 75 cm und einer Maximallänge von 112 cm. Die Körperfärbung ist regional sehr unterschiedlich meist grau- bis rötlichbraun mit helleren Flanken und dunkelbraunen, reihenartig angeordneten Querbändern und Flecken. Der Kopf setzt sich nur mäßig vom Hals ab und ist auf der Oberseite meist einfarbig braun. Ein dunkelbraunes Schläfenband zieht sich vom Mundwinkel über das Auge bis zur Nasenöffnung. Allgemein sind die Jungtiere dunkler mit deutlicherer Zeichnung, bei älteren Tieren verblasst die Färbung. Im nördlichen Bereich des Verbreitungsgebiets finden sich auch einfarbig dunkelbraune Individuen.
Von den 10 bis 14 Infralabialschilden weisen der siebte bis zehnte Sinnesgruben auf, die 10 bis 12 Supralabialschilde sind ohne Gruben. Der Rumpf weist 35 bis 44 schräge Schuppenreihen, 240 bis 295 Bauch- und 37 bis 40 Schwanzschilde, sowie einen ungeteilten Analschild auf.
Die Art kommt in Nordaustralien vom Nordosten Westaustraliens bis zum Nordwesten Queenslands sowie auf einigen küstennahen Inseln vor. Sie besiedelt vielfältige Habitate, von den küstennahen Regenwäldern bis zu Inlandwüsten und kommt auch in direkter Nachbarschaft von menschlichen Siedlungen vor.
Der gefleckte Python ist vorwiegend bodenbewohnend und nachtaktiv. Das Beutespektrum umfasst Echsen, Frösche, Vögel und Kleinsäuger. Die Paarung findet in den kühlen Monaten Mai bis August statt, die Männchen führen ritualisierte Kämpfe um die Weibchen aus. Die 7 bis 15 Eier werden im September oder Oktober gelegt und vom Weibchen umschlungen. Nach der Befruchtung halten die trächtigen Weibchen durch Aufsuchen warmer Stellen eine höhere und stabilere Körpertemperatur[1]. Nach der Eiablage wird das Gelege vom Weibchen umschlungen, was wahrscheinlich nicht zu einer weiteren Erwärmung führt, aber einen verringerten Wasserverlust zur Folge hat[2]. Die etwa 25 cm langen Jungtiere schlüpfen im Dezember.

Children's python (Antaresia childreni) is a species of nonvenomous snake in the family Pythonidae. The species is named after John George Children. It is a nocturnal species occurring in the northern half of Australia and generally found on the ground, although it often climbs trees. Usually growing to about 1.0 m (3 ft) in length or more depending on the polymorphic variant, it is typically a reddish-brown colour, darker on the upper surface, and with many darker blotches, especially on younger specimens. The Stimson's python variant has much stronger and more variable colors; often being adorned with reddish-brown to chocolate blotches against lighter tan.[4] It feeds mostly on small mammals and birds, and as with other pythons, it constricts its prey before swallowing it whole. It is a popular pet among reptile enthusiasts.
Antaresia childreni is one of four species in the genus Antaresia, a genus in the family Pythonidae. The genus is named after the star Antares. John Edward Gray published the original description of the species in 1842, naming it Liasis childreni. Both the common name and the specific epithet, childreni, are in honour of Gray's mentor, John George Children, a curator of the zoological collection at the British Museum around that time.[5] As of 2020 no subspecies are recognized as being valid.[6] Some species of the genus Antaresia were formerly assigned to the genus Morelia.[7] Studies published in 2020 on the members of the genus Antaresia concluded that Stimson's and Children's pythons are synonymous species with different polymorphism. As a result, Stimson's python is now considered a polymorphic variant of Children's python.[8]
Children's python is known by other common names such as banded rock python, small-blotched python, and eastern small-blotched python.[9]
Adults of A. childreni grow to a total length (including tail) around 1–1.5 m (3–5 ft) depending on locality and polymorphic variant. The scales on the top of the head are enlarged, while those on the upper surface of the body are small and smooth, with a rainbow sheen that can be seen when exposed to direct sunlight. The upper surface of the snake is brown with darker spots in five or six longitudinal series in the type variant. A dark streak on each side of the head passes across the eye. The lips are yellowish, spotted with brown. The lower surface of the snake is uniformly yellowish. The head of the snake is distinct from the neck. The nostril is superolateral, pierced in a large semidivided nasal scale. The eye is moderate in size, with a vertical pupil. The body is slightly laterally compressed. The tail is short. About 41 to 45 rows of dorsal scales cross the snake's back, and 257 to 287 ventral scales are seen along the lower surface. A single undivided anal scale is found immediately in front of the anus, and 38 to 53 subcaudal scales are on the lower surface between the anus and the tip of the tail, all or mostly in two rows. The polymorphic variant known as the Stimson's python has much stronger and more variable colors; often being adorned with reddish-brown to chocolate blotches against lighter tan.[4]
The rostral is broader than high, barely visible from above. The internasals are slightly longer than broad and are shorter than the anterior prefrontals. The second pair of prefrontals is in contact at the midline, or is separated by a small shield. These posterior prefrontals are sometimes broken into several shields. The frontal is one and a half times as long as broad, slightly shorter than its distance from the end of the snout, longer than the small parietals. Three to 10 small loreal shields are present, some almost granular, with 11 to 13 upper labials. Three or four of the posterior lower labials have deep pits.
The anterior maxillary teeth and anterior mandibular teeth are very long, gradually decreasing in size posteriorly. The premaxillary bone also has teeth.[2][10]
A. childreni is found in Australia in the extreme north of Western Australia, the northern third of the Northern Territory, and northern Queensland, and also on the islands of the Torres Strait. The Stimson's python variant is found throughout an even greater range; it occupies much of the interior of Australia, from Queensland to Perth.[4]
The type locality is given by Gray (1842) as "—?", is listed as "N.W. Australia" by Boulenger (1893) in his Catalogue of the Snakes in the British Museum (Natural History). Volume I., and is listed as "unknown" in Stimson (1969).[7]
A. childreni occurs specifically in the region spanning the coast between the Kimberleys in Western Australia to Mount Isa in northwestern Queensland.
Children's python is found in a variety of natural habitats, including forest, savanna, shrubland, desert, grassland, and freshwater wetlands.[1] In Alice Springs the cosmopolitan tick Amblyomma limbatum has been collected from a Children's python.[11]
The diet of Children's python consists of reptiles, birds, and small mammals, particularly microbats, which it catches by dangling from stalactites in caves, which they commonly inhabit, and snatching them out of the air as they fly past.
A. childreni is oviparous, with up to 25 eggs per clutch. Females brood their eggs through a seven-week incubation period by coiling around them and occasionally shivering to keep them warm, which also affords the eggs some protection from predators. Juveniles are heavily blotched, but gradually become reddish-brown or brown as they mature. The Stimson's variant often becomes more starkly contrasted by comparison as it matures depending on locality. Males in captivity have been seen to fight over females, suggesting these snakes will fight for mates in the wild. However, combat in wild individuals of this species has never been witnessed. When the males fight, they use their spurs to scratch their opponents, and will also strike and bite one another until one submits.[4]
Children's python is often kept as a pet worldwide due to its small size, docile temperament, strong feeding response, resiliency and easy captive care. It is often seen as a good beginner species for keeping reptiles, particularly snakes. High levels of hygiene will reduce the risk of disease transfer to pet owners. While not as popular or diverse in colors as ball pythons or other larger species, A. childreni can range in color from albino and leucistic to ebony, melanistic, ghost, and piebald color morphs[12] to name a few. The varying coloration between individuals also makes it quite attractive to many who work with and breed exotic reptiles. In captivity, the members of this genus are very tolerant of differing humidity levels ranging from 20%-80% due to the wide range of habitats they occur in, and shedding problems that occur in captive animals are usually the result of temperatures being too high or low rather than problems with humidity. Antaresia species are also fairly easy to breed, though some individuals (mostly males) may refuse to eat when they are interested in mating.[4] The lifespan of captive specimens has been known to exceed 30 years. Juveniles are fed baby, hairless mice, while larger individuals can be fed on adult mice or small rats. Feeding should occur roughly once a fortnight.

Antaresia childreni
Le Python de Children (Antaresia childreni) est une espèce de serpents de la famille des Pythonidae[1].
Cette espèce est endémique d'Australie. Elle se rencontre dans l'extrême Nord de l'Australie-Occidentale, le tiers Nord du Territoire du Nord et le Nord-Est du Queensland[1].
Adulte, ce serpent constricteur mesure en moyenne environ de long, 110 cm pour les plus grands. Les écailles sur le sommet de la tête sont de grande taille, plus petites et lisses sur le reste du corps avec un aspect irisé lorsque l'animal est exposé au soleil. Il est l'un des plus petits pythons.
Son environnement naturel est plutôt aride. Cette espèce peut également se trouver dans des grottes où il chasse des chauves-souris.
Il se nourrit de reptiles, d'oiseaux et de petits mammifères notamment de petites chauve-souris qu'il attrape au vol dans les grottes où elles vivent en se penchant aux stalactites et en les saisissant au passage.
Ovipare, la femelle pond environ vingt-cinq œufs qui incuberont pendant sept semaines. La mère reste à proximité pour défendre le nid et éventuellement réchauffer les œufs si la température baisse.
Cette espèce est nommée en l'honneur du zoologiste britannique John George Children (1777-1852).

Il pitone di Children (Antaresia childreni (Gray, 1842)) è un serpente appartenente alla famiglia Pythonidae.
Gli esemplari più piccoli misurano circa 70 cm, ma può arrivare ad una lunghezza massima di 1 m. A differenza delle femmine, i maschi hanno una coda più lunga e robusta. Se viene minacciato si difende mordendo ma, come tutti i pitoni, non è velenoso.
Passa gran parte del tempo nascosto sotto le rocce.
Si ciba prevalentemente di lucertole, anche se tende anche a mangiare piccoli mammiferi e uccelli.
È presente, in prevalenza nella parte settentrionale dell'Australia.

童蟒(學名:Antaresia childreni)是蛇亞目蟒科下的一個無毒蛇種,主要分布於澳洲。其命名者約翰·愛德華·格雷取其學名為「childreni」,目的是為了紀念其業師,大英博物館前館長及著名動物學家約翰·喬治·喬尊(John George Children)。童蟒中文名字的譯法,是意譯而非音譯,其實亦有不準確的地方。目前童蟒未有任何亞種被確認。[2][3]
成年的童蟒身長約有90公分長,最高紀錄更達1.1米。其頭頂的鱗片較為寬闊,相對而言其它部位的鱗片則顯得細碎及平滑,在陽光照射下會反射出色彩,令其十分顯眼。
童蟒是卵生動物,每次約能生產25枚蛇卵。母蛇會在產卵後的七個星期內對蛇卵進行孵育,並經常磨擦蛇卵表殼以保持一定溫度,同時對其加以保護。剛破卵而出的幼蛇身上有著顯著的斑點,在牠們成長的過程中,這些斑點會逐漸褪成棕紅色或棕色。
童蟒主要分布於澳洲一帶,包括西澳大利亞州和北部地區的北方,與及昆士蘭的東北方,同時在托雷斯海峽附近的島嶼上亦能找到牠們的蹤影。其標本產地為「澳洲西北部」,但實際位置迄未尚未剖明。[1]童蟒現在更逐漸成為西澳大利亞州內金巴利地區與艾莎山脈之間的一個地區特有種。
童蟒主要進食爬蟲動物、鳥類及一些細小的哺乳類動物,尤其是微蝙蝠。要捕食微蝙蝠的時候,童蟒會爬進山洞並攀上鐘乳石,並以倒垂擺盪的姿態捕捉飛過的微蝙蝠。
童蟒是相當常見的寵物蛇種,因為牠生活要求並不高,進食習慣方面亦沒有苛刻的條件。而且童蟒的壽命相當長,曾有可達超過30歲的紀錄。童蟒幼蛇可以用細小的幼鼠餵飼,長大到一度程度後就要以體型較大的成年鼠類作為其食糧。
