Der Stimson-Python (Antaresia stimsoni), auch Stimsons Python, ist eine Art aus der Gattung Antaresia in der Familie der Pythons (Pythonidae).
Der Stimson-Python hat einen länglichen, kaum vom Hals abgesetzten Kopf. Kopf- und Körperoberseite sind braun mit dunkleren, großen Flecken, die auf dem Körper paarig sind und teilweise auf die Körperseiten übergreifen, so dass sich ein gebändertes Erscheinungsbild ergibt. Die Bauchseite ist cremefarben bis weiß. Färbung, Zeichnungsmuster und Pholidose variieren stark innerhalb des Verbreitungsgebietes. Erwachsene Exemplare werden durchschnittlich 70 bis 80 cm lang, die Maximallänge liegt bei 140 cm.
Die Pholidose variiert im Verbreitungsgebiet stark. An den großen Frontalschild grenzt je Kopfseite ein Supraokularschild. Ein Paar Internasalschilde und ein bis drei Paare Präfrontalia sind vorhanden. Das einzelne Paar Parietalschilde ist gelegentlich von ein bis drei Interparietalschilden geteilt. 4 bis 18 Lorealschilde und zwei bis drei Präokularschilde sind vorhanden. Das Maul ist von 10 bis 15 Supralabialschilden und 11 bis 16 Infralabialschilden umgeben. Der Rumpf weist 30 bis 47 Reihen glatter Schuppen in seiner Mitte, 243 bis 302 Ventralschilde und 30 bis 45 meist geteilte Subkaudalschilde und einen ungeteilten Analschild auf.
Zuweilen werden zwei Unterarten unterschieden, von denen die östliche A. s. orientalis eine kräftigere Körperzeichnung aufweist und eine geringere Zahl von Schuppen und Schilden in der Rumpfmitte aufweist als die Typusunterart A. s. stimsoni.
Der Stimson-Python hat das größte Verbreitungsgebiet aller australischen Pythons. Die Art findet sich von der Westküste über eine Reihe vorgelagerter Inseln bis in den Großteil des australischen Inlands und fehlt nur im nördlichen, östlichen und südlichen Küstenbereich. A. s. stimsoni findet sich dabei in Westaustralien von Perth bis zur Pilbara-Region, A. s. orientalis im Rest des Verbreitungsgebiets.
Zuweilen kommt es zu Bastardisierungen mit Antaresia childreni und Antaresia maculosa.
Die Art kommt in unterschiedlichen Habitaten, von Berghängen über Ebenen bis zu Buschland, vor und hält sich bevorzugt in Felsspalten und Höhlen auf.
Der Stimson-Python ist vorwiegend nachtaktiv und jagt Amphibien, Echsen, Vögel, Fledermäuse sowie andere Kleinsäuger. Im australischen Frühjahr legen die Weibchen bis zu zehn zu einem Gelege verklebte Eier, aus denen nach 51 bis 70 Tagen die 25 bis 30 cm langen Jungen schlüpfen.

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.

斯氏星蟒（學名：Antaresia stimsoni）是蛇亞目蟒科侏儒蟒屬下的一個蛇種，主要分布於澳洲。斯氏星蟒的學名「Stimsoni」是為了紀念大英博物館的A.F.斯添遜，不過在英語中偶爾也會出現把斯氏星蟒串成「Stimpson's Python」的錯誤。在澳洲，斯氏星蟒是常見的寵物蛇種之一。目前尚未有任何亞種被確認。[2]
作為蟒科的成員之一，斯氏星蟒跟其它蟒蛇同樣是無毒的蛇種。牠們捕殺獵物的方式，是一貫地以身體纏繞並勒死對方。不過斯氏星蟒的鼻端沒有健全的熱能探測氣孔，因此只能倚賴舌頭與嘴唇去感應獵物。斯氏星蟒的體型偏小，是陸行性蛇類，成年的斯氏星蟒約長一米。
斯氏星蟒主要分布於澳洲的西澳沿海地區，並擴展至大部分的州份（除了維多利亞州），遠至大分水嶺。而在澳洲的北部、東部及南部均不曾發現斯氏星蟒。[1]
斯氏星蟒多棲身於乾燥的內陸地區，主要出沒於岩石地帶，間中亦會出現在灌木林、沙漠，很少在寬闊平廣的地方現身。牠們是夜行蛇類，居住的地方往往來自強佔其它動物的洞穴、山洞。另外，斯氏星蟒是被動的獵食者，牠們花費很多時間等待獵物自行出現，並加以捕殺。而牠們的主要食糧是蜥蜴、蛙類與及小型的哺乳類動物。繁殖方面，斯氏星蟒是卵生蛇類，母蛇每次約能誕下7至9枚蛇卵。
