Distinguishing Features

  • Small python (relative to other pythons), typically around 1–1.5 m in length
  • Reddish-brown to brick-red tones common; patterning can be subdued compared with some other Antaresia
  • Heat-sensing labial pits typical of pythons
  • Non-venomous constrictor; robust body for its size

Did You Know?

Accepted name: Antaresia bredli; common name: Centralian python (Pythonidae).

Adult total length is typically ~1.5-2.0 m, with large individuals reported to about 2.5 m in some field/captive accounts (e.g., Wilson & Swan, field guide summaries).

It has heat-sensing labial pits that help locate warm-blooded prey in low light-shared across many pythons, but present in Antaresia.

Females coil around their eggs and brood them, using muscular contractions to elevate clutch temperature-classic python parental care documented across Pythonidae.

In the wild it shelters in rock crevices and gorges of central Australia, where stable temperatures and humidity reduce water loss in an arid climate.

Longevity in captivity is commonly reported at 20+ years, with some keepers/zoo records citing ~25-30 years under excellent care (husbandry/zoo record summaries).

Unique Adaptations

  • Arid-zone water economy: like other desert reptiles, it minimizes water loss via scaled skin and excretes nitrogen largely as uric acid, conserving water compared with mammals.
  • Labial "heat pits" (infrared sensitivity): assists in pinpointing endothermic prey even in darkness or within complex rocky terrain.
  • Highly flexible skull and jaw ligaments allow swallowing prey wider than the head-key for taking rodents, small birds, and other vertebrates.
  • Coloration and patterning (often reddish-brown to brick tones) provides camouflage against iron-rich central Australian rocks and soils.
  • Strong climbing and gripping ability for a 'small python': useful in rugged gorge country and when accessing ledges/roost sites.
  • Temperature buffering via shelter choice: retreating into deep crevices reduces exposure to extreme daytime heat and desiccating winds.

Interesting Behaviors

  • Ambush predation: typically waits at a likely travel route (rock ledges, crevice mouths) and strikes rapidly, then constricts prey.
  • Crepuscular/nocturnal activity is common in hot months; individuals may bask at cooler times to reach optimal body temperature.
  • Rock-crevice fidelity: often reuses the same shelter sites, especially in complex gorge systems and rocky outcrops.
  • Constriction technique: coils tighten with each exhalation of the prey, rapidly restricting blood flow-efficient for small mammals and birds.
  • Maternal brooding: the female remains with the eggs until hatching, defending and thermoregulating the clutch.
  • Seasonal feeding/fasting: can go extended periods without meals, then feed opportunistically when prey is abundant after rain-driven pulses.

Cultural Significance

In central Australia, pythons are powerful beings in Aboriginal stories tied to waterholes and land shapes. Bredl's Python (Antaresia bredli) lives there, is kept by snake hobbyists, and is named for Joseph Bredl and the star Antares.

Myths & Legends

Rainbow Serpent traditions (many language groups across Australia): an immense ancestral serpent linked to the creation of rivers, waterholes, and rain-often said to live in deep pools and punish disrespect of sacred waters.

Water-serpent stories from the Western Desert and parts of central and northern Australia: powerful serpent beings associated with permanent water sources in otherwise dry country, emphasizing proper law and ceremony around springs and soaks.

A Dreaming story from Ayers Rock and the Olgas tells of a python woman fighting a venomous snake man. Their acts are shown in the land and taught as law about duty and family.

In Central Desert Dreaming stories near Alice Springs, a giant carpet-snake ancestor (Bredl's Python, Antaresia bredli) moved through ranges and gorges, creating land features and guiding rules for how people should behave on traditional lands.

Naming heritage (historical anecdote): the species epithet bredli commemorates Joseph Bredl (associated with the Alice Springs region), reflecting a long practice of linking central Australian fauna with the people who documented and protected it.

Behavior & Ecology

Social Solitary Group: 1
Activity Nocturnal, Crepuscular, Cathemeral
Diet Carnivore Small mammals (rodents)
Seasonal Hibernates

Temperament

Secretive and refuge-oriented (especially in daylight/heat)
Generally non-aggressive toward large animals but strongly defensive when threatened or handled (hissing, striking, biting)
Seasonally variable surface activity: increased movements during cooler periods and around breeding season; reduced exposure during extreme heat

Communication

hiss Forced exhalation used in threat displays
chemosensory signaling via tongue-flicking and vomeronasal organ Tracking prey and conspecific scent trails; sex pheromones likely important in mate finding, as in other pythonids
tactile communication during courtship/copulation Body alignment, tail positioning, cloacal contact
visual/postural threat displays Neck/body inflation, head elevation, strike posture
substrate-borne vibration cues from movement at close range Incidental, not a specialized signaling system

Human Interaction

Domestication Status

Wild

Antaresia bredli (Bredl's python or Centralian python) is wild and native to central Australia. It has been bred widely in captivity since the late 20th century but is not truly domesticated. It is commonly kept as a pet, used in zoos and education, grows about 1.2–2.0 m, and often lives 20–30 years.

Danger Level

Low
  • Defensive bites (superficial puncture/laceration risk; non-venomous).
  • Zoonotic pathogens associated with reptiles (notably Salmonella) via handling or contaminated surfaces; risk mitigated by hygiene.
  • Allergic reactions (rare; usually related to dander/substrate/feeder animals rather than the snake itself).
  • Constrictor hazard to humans is negligible for this species' typical adult size; primary risk is from mishandling (e.g., feeding response bites).

As a Pet

Suitable as Pet

Legality: Legality of Bredl's Python (Antaresia bredli) varies. Often legal in much of the U.S. and other countries, but some places need permits. In Australia, state/territory licenses and care rules apply. Check local laws.

Bredl’s python is a nonvenomous snake that lives in an isolated mountain range in central Australia.

This semi-arboreal snake shelters in tree hollows and crevices and comes out to hunt when temperatures in its harsh climate are more comfortable.

It is a docile snake that hunts various warm-blooded prey including marsupials, birds, and feral cats in its home range.

3 Amazing Facts About Bredl’s Python

  • Wild female Bredl’s pythons only breed every 3-4 years because of the strain it takes on the body.
  • It only lives in central Australia near Alice Springs in the MacDonnell range.
  • People originally assumed that it was a desert variant of carpet python.

Where to find Bredl’s Python

Bredl’s python inhabits a mountainous area in central Australia, calling the southern region of the Northern Territory home. It is comfortable in various habits including savanna, forests, inland wetlands, cliffs and mountain peaks, and desert. This snake is also known as the Centralian carpet python. Most individuals are found within 300 miles of the town of Alice Springs in the MacDonnell Mountain range.

This harsh habitat regularly sees summer daytime highs over 100F and winter lows below freezing. Rain in the area is highly seasonal, and the summer tends to see more precipitation than winter. The area surrounding the mountain range is a brutally hot desert that pythons cannot pass, which makes the mountains an oasis for many animal species.

This snake is semi-arboreal and frequents trees and shrubs, especially near riverbanks; it also occurs in Acacia woodland. It shelters in caves and rock crevices during the day through the hot summer months and becomes active at night when temperatures fall.

However, spring and fall bring cooler night-time temperatures, and the snake ventures out during the day. There can be as much as a 30-degree difference between day and night temperatures all year long.

This species feeds on possums, rock wallabies, and birds nesting in tree hollows. It’s an opportunistic predator, so it also preys on feral cats and rabbits when they’re available.

Evolution and Origins

Pythons are native to Southeast Asia and were first imported to the US as exotic pets. In the 1980s, Miami was home to thousands of these snakes as the exotic pet trade grew.

Findings indicate that snakes evolved on land, as opposed to in water, during the middle of the Early Cretaceous period (about 128.5 million years ago), and that they most likely began in the former supercontinent of Laurasia. During this time, numerous species of birds and mammals appeared on Earth quickly.

Pythons have been around for around 15 million years, according to fossil records. The first snake on Earth probably originated on land, not in the water a “protosnake” progenitor that most likely had tiny hind legs and lived around 120 million years ago has been identified through genetic research and comparisons of recently discovered fossils with contemporary snakes.

Different Types

Here are a few different types of pythons:

Reproduction

Data on mating in the wild is limited, most of what we know about breeding them comes from breeders in different parts of the world. In captivity, most male Bredl’s pythons show interest in breeding in their third year, and females are often four or five years old before they begin to breed.

In the wild, scientists believe that mating occurs during August and September. Then, from October through December, females lay 13-47 eggs that hatch during January and February.

Scientific Name and Classification

These semi-arboreal snakes are often found in trees.

Naming in the scientific community sometimes reflects the location where they find an organism, sometimes its color, and sometimes to honor a person. Josef Bredl (1948-2007) was an Australian herpetologist. He started the Edward River Crocodile Farm and owned the Renmark Reptile Park in South Australia.

This python, while it is currently considered a full species, may find itself moved into the realm of subspecies. Some scientists include it with the carpet python (Morelia spilota) complex and when scientists do more genetic research, they may discover that Bredl’s python fits better there. That said, its natural habitat is quite isolated from the other Morelia species.

It was first discovered in the 1870s, but at the time was considered a desert variation of the very common carpet python, and they called it the Centralian carpet python. Graham Gow described it as a new species in 1981 – calling it Bredl’s python (Morelia bredli). He cited its much smaller head and dorsal scales and isolation from any other python species as justification for elevating it to the status of full species.

Population and Conservation Status

As of 2017, the IUCN Redlist of Threatened Species considered Bredl’s python a species of “Least Concern.” Within its home range, it is common with a stable population. At one time, there was a high demand for this species in the illegal pet trade, but there are enough captive-bred individuals now that finding one from a breeder shouldn’t be a problem.

Breeders in some locations have cross-bred Bredl’s python with carpet pythons to come up with new color patterns. However, this practice is falling out of favor in some areas in order to preserve the species in its original state.

Appearance and Description

This snake is known for being very docile and even-tempered.

This species averages between 6.5 and 8.5 feet long with the occasional 9-10 footer. Despite its sometimes large size, it is easy to handle.

Unlike those in the carpet python complex, Bredl’s python doesn’t show as much pattern variation. It is usually reddish-brown with white to beige spots or bands which are usually outlined in black. It has a powerful constrictor-type body and its scales are smooth and glossy.

This snake has that classic “python” head, with the large jaw muscles typical of Morelia species snakes. It is somewhat triangular with a blunt snout and elliptical pupils. Bredl’s python has large, noticeable heat-sensing pits both on the upper front of its snout and along the lower rear labials.

How Dangerous is Bredl’s Python

These snakes are nonvenomous, so a bite shouldn’t cause permanent damage. However, their teeth are something to avoid. Owing to their Morelia ancestry, they have big teeth and powerful jaw muscles. Many species in this genus prey on birds and other fast-moving animals, so they have specialized jaws to make capturing them a possibility.

Scary teeth aside, breeders and keepers say this is a remarkably calm snake. It only rarely strikes, and most often, those strikes are food-response and not aggression.

Behavior and Humans

These snakes have big teeth and strong jaws.

This species, like other Australian natives, is protected against export to other countries. The snakes live in a fairly remote part of the country that doesn’t see a lot of traffic. As a result, there isn’t a vast amount of research on them.

This species is becoming popular in the pet trade, and for a while was one of the most sought-after in the European Union. Most specimens sold as pets are captive-bred individuals that came from Germany or the Czech Republic breeding lines.
