The pygmy python (Antaresia perthensis), also known as the anthill python, is a species of snake found in Western Australia. Their common names are due to their being the smallest member of the family Pythonidae and often being found in termite mounds. No subspecies are currently recognised. [2]

Contents

The specific epithet is derived from the Western Australian state capital, Perth—a city which is not, ironically, within the range of the species. The global biodiversity database iNaturalist has documented a number of different visual sightings of the pygmy python within the state of Western Australia, with the nearest physical sighting to Perth having occurred near Reedy, some 680 km (422.53 mi) north and slightly further inland of the capital. [3] [4]

Description

Adults grow to about 50 cm (19.5 in) in length and have a weight near 210 grams. Neonates are about 8 inches (20 cm) in length and about 4 grams in weight. After a year they average about 25 grams in weight. This makes them smaller than both the Children's python, A. childreni , and the spotted python, A. maculosa . A. perthensis usually has a redder background ground color than these other species and their spots fade, or become less distinct, as they mature. In contrast, the ground color is lighter in childreni and maculosa, while their spots stay better defined throughout their life.

Distribution and habitat

The pygmy python is native to Australia, primarily endemic to the northwestern regions of the state of Western Australia and on some coastal islands. The type locality given is "Perth, West Australia" (Western Australia), an erroneous assumption of the place where the specimen was collected. This historical unfamiliarity of Europeans with the place of a specimen's collection has given rise to other 'naming peculiarities'. [4] According to L.A. Smith (1985), the type locality is unknown. [1]

The pygmy python has a number of confirmed visual sightings entered on iNaturalist (a global biodiversity website, app and nature-minded social network); sightings have been documented in and around several areas of Western Australia, including Cape Range National Park, Dampier, De Grey, East Lyons River, the Hamersley Range and Karijini National Park, Marble Bar, the Murujuga (Burrup) Peninsula, Pannawonica, Peedamulla, and Port Hedland. [5]

Housing

In captivity anthill pythons can be housed (and bred) in something as small as a 20 gallon tank. Although reptile-specific enclosures are best, a simple fish tank may be used for short- or long-term housing. They may be fed mice as part of their regular diet, supplemented with fuzzy rats. Anything larger is usually a stressor on their system, although they will still try to eat it. Once anthill pythons get started eating they rarely refuse a meal except for breeding season or during part of their shedding cycle.

After even about 6 months they still are measured in gram weight due to their small "pocket" size.[ citation needed ]

Reproduction

The pygmy python is oviparous, with 5-8 eggs per clutch. The females will stay coiled around the eggs (lifting them off the substrate) and incubate them until they hatch, which is usually after 50–60 days.

In captivity

This snake is a popular exotic pet.[ citation needed ]

<i>Antaresia</i> Genus of snakes

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. Four species and two subspecies are recognized, although they were all considered part of the same species until recently. 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.

<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.

<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 colours; 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.

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.

<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.

They are recognised as a subspecies of Liasis olivaceus, separating the population from the olive python found to the east. It is a large snake, most often around 2.5 metres in length, although individuals may attain a larger size. The python is an ambush predator, using a sit and wait method at a path or beneath the water to capture a variety of animals that inhabit the arid surroundings. The range of prey includes amphibians, birds and other reptiles, and mammals as large as a rock wallaby.

The spotted mulga snake, also known commonly as Butler's black snake and Butler's snake, is a species of venomous snake in the family Elapidae. The species is endemic to Western Australia. It is a member of the genus Pseudechis, dangerously venomous snakes that can intimidate an opponent by raising the head and presenting a hood. This cobra-like threat display is supported by the ability to produce a very large amount of venom.
