The Australian scrub python is the country's largest snake

The Australian scrub python, also known as Simalia kinghorni, Kinghorn's python, or simply the scrub python, is the country's largest snake species. It is indigenous to the forests of northern Australia, specifically the tropical rainforests of far north Queensland. The scrub python is commonly considered arboreal or tree-dwelling, making it one of the world's largest and longest arboreal snake species.

The scrub python has a distinctive appearance, with an ornate dorsal pattern consisting of browns and tans and an iridescent sheen. Its belly is usually white, sometimes with yellow hues. The top of its head is covered with large symmetrical shields, and it possesses heat-sensing pits on the rostral and some labials.

In terms of size, the Australian scrub python can reach impressive lengths. While there have been unverified reports of individuals exceeding 6 meters in length, the largest seriously measured female scrub python had a total length (including tail) of 5.65 meters (18.5 feet). On average, adult females measured in one study had a snout-to-vent length (SVL) of 2.68 meters (8.8 feet) and weighed approximately 3.4 kilograms (7.5 pounds).

The scrub python is a formidable predator and is considered one of the largest land predators in Australia. Its diet consists mainly of birds and mammals, including rainbow bee-eaters, bush rats, northern quolls, and various species of bandicoots and possums. Notably, one of the largest recorded prey items of the scrub python was a 10-kilogram (22-pound) adult mobile wallaby, which was consumed by a female python measuring 4.33 meters (14.2 feet) in length.

In addition to its size and hunting prowess, the Australian scrub python is known for its protective maternal instincts. Female scrub pythons exhibit maternal care by coiling around their eggs to protect them and regulate their temperature through muscle contractions, ensuring the eggs remain warm during the two-month incubation period.

Pythons in Australia can grow to over 8 metres long

The size of the scrub python can vary depending on its habitat, age, and gender. Females tend to be larger than males, with an average length of 2.68 metres and a weight of 3.4 kilograms. While most scrub pythons range between 3 to 7 metres in length, there have been reports of exceptionally large individuals. One of the largest recorded specimens was a female python measuring 4.33 metres long, which consumed a 10-kilogram adult wallaby, an impressive feat demonstrating the strength and size of these reptiles.

The scrub python is a skilled hunter, often emerging under the cover of darkness to search for its prey. It feeds on a variety of animals, including small mammals, birds, and reptiles, and even larger creatures such as juvenile kangaroos and wallabies. Its hunting technique involves using its large teeth to secure prey before coiling its muscular body around the victim, causing suffocation.

While the scrub python is the largest python species in Australia, there are other notable mentions, such as the Olive Python, which can reach lengths of up to 4 metres, and the Black-headed Python, which can grow up to 3 metres in length. These pythons showcase the diverse range of sizes and adaptations within the python family in Australia.

Pythons are non-venomous and kill prey through constriction

Pythons are non-venomous snakes that kill their prey through constriction. They are found in regions like sub-Saharan Africa, Southeast Asia, and Australia. Pythons are ambush predators that primarily kill prey by constriction, causing cardiac arrest. They do not possess venom and, therefore, do not have fangs. Instead, they use their sharp, backward-curving teeth to grasp their prey and then quickly wrap a number of coils around it, causing death by suffocation or cardiac arrest.

The lack of venom is a defining characteristic of the python family. They rely on their powerful muscles to constrict their prey, and their teeth are designed for holding, not injecting toxins. Studies have shown that some pythons can exert pressures of around 6 pounds per square inch (psi) during constriction, which is enough to cut off blood flow and cause asphyxiation. This is in contrast to venomous snakes such as rattlesnakes, which deliver a venomous bite and then release their prey, waiting for it to succumb to the venom before consuming it.

While pythons are not venomous to humans, they can and do bite, and a python bite can cause severe damage to the body. Pythons are also known to carry a host of potential health issues for humans, as they are disease vectors for illnesses such as Salmonella, Chlamydia, and Leptospirosis. These diseases may be transmitted to humans through excreted waste, open wounds, and contaminated water. Therefore, while pythons may not pose a danger through venom, they can still be dangerous to humans in other ways.

In Australia, one of the most well-known python species is the Australian scrub python (Simalia kinghorni), which is indigenous to the forests of northern Australia. It is one of the world's longest and largest snakes and is the longest and largest snake in Australia, reaching lengths of up to 8 meters (26 feet) and weighing over 25 kilograms (55 pounds). The Australian scrub python is a skilled hunter, often spotted under the cover of darkness in search of its prey, which includes rodents, fruit bats, possums, and even juvenile kangaroos.

Another python species found in Australia is the black-headed python (Aspidites melanocephalus), which is native to northern Australia, from Western Australia to Queensland. These pythons typically grow to lengths of 1.5-2 meters (4.9-6.6 feet) but can reach a maximum length of 3.5 meters (11 feet). They are known to feed on large venomous snakes like the King Brown and other reptiles.

Pythons in Australia can be as small as 50 cm long

Pythons in Australia vary in size, with some growing to enormous lengths, such as the Australian scrub python, which can reach up to 8.5 metres (28 feet) in length. However, it is important to note that smaller python species also exist in the country. Indeed, pythons in Australia can be as small as 50 cm long, such as the pygmy python, which is native to Western Australia. This species is characterised by its reddish-brown colouring with pale spots, well suited to its natural habitat of rocky outcrops. While it typically reaches a length of around 1 metre, some individuals have been recorded at smaller sizes, as little as 50 cm long.

Another small python species found in Australia is the Children's Python, named after JG Children, an English naturalist. These pythons typically have a brown colouration with smooth-edged, darker brown blotches along their backs, and a creamy belly. They are found in Queensland, the Northern Territory, and Western Australia, and they rarely grow larger than a metre in length, with an average length of around 75 cm.

The Black-headed Python is another Australian python species that typically grows to a maximum length of 3 metres. However, individuals as small as 50 cm have been observed. This python is easily identified by its glossy black head, neck, and throat, and it lacks the distinct neck narrowing seen in most other pythons. It inhabits a wide variety of habitats across the northern half of Australia and is typically nocturnal in its habits.

While these smaller python species exist in Australia, it is worth noting that the country is also home to some of the world's largest python species, such as the Australian scrub python and the Burmese python, which can reach impressive lengths and weights.

Pythons are commonly found in Queensland, Northern Territory and Western Australia

Australia is home to 14 species of pythons, which is close to half of the world's total of 31. Pythons are commonly found in Queensland, the Northern Territory, and Western Australia.

Queensland is home to the Australian scrub python, which is one of the world's largest snakes and the largest snake in Australia. It is commonly found in the tropical rainforests of far north Queensland, where it preys on large animals. The scrub python can reach up to 8 meters (26 feet) in length and weigh in excess of 25 kilograms (55 pounds). It is non-venomous and uses its large teeth to secure its prey before wrapping its muscular body around it, suffocating it, and consuming it whole. Its diet includes rodents, fruit bats, possums, and even juvenile kangaroos.

The Northern Territory is home to a rare, endangered python that can grow up to 4 meters in length and has a unique head structure with grey-brown coloring. This python is endemic to Arnhem Land in the Northern Territory.

Western Australia is home to a python that can reach up to 3.5 meters in length. It is commonly found in the arid zones of the state and is often mistaken for venomous species due to its bold coloring. It has a black head and a banded body, with distinctive blotches and fewer heat-sensing pits, making it well-adapted to its environment.
