Antaresia is a genus of pythons, nonvenomous snakes in the family Pythonidae. The genus is native to Australasia. The genus is known by the common name Children's pythons, the name of the type species, Antaresia childreni . Gray named A. childreni in honour of his mentor, John George Children, who was a curator of the zoological collection at the British Museum around that time. It contains the smallest members of the Pythonidae. [2] Four species and two subspecies are recognized, although they were all considered part of the same species until recently. [3] A newly described form called the pygmy banded python may be a distinct species, but analysis has not yet been performed on this animal. The largest recorded examples of Antaresia species have all been males, suggesting males of the known species in this genus may compete for females. This behavior has never been witnessed in the wild, and has only been witnessed in captive specimens. [4]

Taxonomy

The generic name, Antaresia, is taken from the star Antares in the constellation Scorpius. The generic name was created in 1984 by Wells and Wellington in a revision of Children's pythons, those previously described as a single species in the genus Liasis . Despite a petition to suppress the taxonomic work of these authors, it gained wide acceptance and publication in 1991.

Four species and two subspecies are currently recognized in the genus Antaresia, which is contained by the family Pythonidae; infraspecific ranks have also been described. [3]

A subspecies, A. stimsoni orientalis was described by L.A. Smith (1985), but was not recognized as valid by Barker & Barker (1994). [1] It is now recognized as valid by ITIS, as well as A. stimsoni stimsoni.

In captivity

The members of the genus Antaresia are often kept as pets due to their small size, docile temperaments, strong feeding responses, resiliency and easy captive care. They are often seen as a good beginner species for keeping reptiles, particularly snakes. While not as popular or diverse in colors as ball pythons, these snakes can range in color from albino and leucistic to ebony, melanistic, and piebald color morphs to name a few. The varying coloration between individuals also makes them 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]

<i>Xenopeltis</i> Genus of snakes

Xenopeltis, the sunbeam snakes, are the sole genus of the monotypic family Xenopeltidae, the species of which are found in Southeast Asia. Sunbeam snakes are known for their highly iridescent scales. Three species are recognized, each one with no subspecies. Studies of DNA suggest that the xenopeltids are most closely related to the Mexican burrowing python and to the true pythons (Pythonidae).

<span class="mw-page-title-main">Green tree python</span> Species of snake

The green tree python is a species of snake in the family Pythonidae. The species is native to New Guinea, some islands in Indonesia, and the Cape York Peninsula in Australia. First described by Hermann Schlegel in 1872, it was known for many years as Chondropython viridis. As its common name suggests, it is a bright green snake that can reach a total length of 2 m (6.6 ft) and a weight of 1.6 kg (3.5 lb), with females slightly larger and heavier than males. Living generally in trees, the green tree python mainly hunts and eats small reptiles and mammals. It is a popular pet, and numbers in the wild have suffered with large-scale smuggling of wild-caught green tree pythons in Indonesia. Despite this, the green tree python is rated as least concern on the IUCN Red List of endangered species.

<i>Morelia spilota</i> Species of snake

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.

<span class="mw-page-title-main">Children's python</span> Species of reptile

Children's python 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. 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.

However, two subspecies were recognized as of 2020; A. m. maculosa and A. m. peninsularis.

<span class="mw-page-title-main">Amethystine python</span> Species of snake

The amethystine python, also known as the scrub python or sanca permata in Indonesian, is a species of non-venomous snake in the family Pythonidae. The species is found in Indonesia and Papua New Guinea. Popular among reptile enthusiasts, and noted for its coloration and size, it is one of the largest snakes in the world, as measured either by length or weight, and is the largest native snake in Papua New Guinea. Until 2000, the larger S. kinghorni was generally considered a subspecies of S. amethistina, and this change of classification has still not been universally reflected in literature. Because of this issue, S. amethistina has often been described as the largest snake in Australia, but this is not accurate since under the current classification, this species does not occur in Australia.
