What You'll Learn
Amethystine pythons are Australia's largest native snake
Amethystine pythons, or Simalia amethistina, are Australia's largest native snake species. They are long, slender, nonvenomous snakes belonging to the Pythonidae family. Amethystine pythons are found in coastal rainforests in Indonesia, New Guinea, and northern Australia. They are not currently at risk of extinction and are considered invasive in some areas outside their native range, particularly in South Africa.
Amethystine pythons are highly adaptable, nocturnal predators that can thrive in various landscapes, including tropical rainforests, mountains, and areas near human habitation. They are excellent climbers, which allows them to navigate through trees and rocky terrains. Their bodies are muscular and robust, adapted for their constricting hunting method. They capture their prey by coiling around it and squeezing it to death, rather than relying on venom. The diet of the amethystine python consists primarily of birds, bats, rats, possums, and other small mammals.
Amethystine pythons have a distinctive appearance with a base colour ranging from dark green to dark brown or even black, overlaid with lighter markings. Their scales have a milky iridescent sheen, which, in the right light, displays hues of amethyst, giving them a mesmerizing and camouflage-enhancing appearance. They have large symmetrical scales on the crown of their head, and heat-sensing pits on their faces, which help them detect their prey's body heat in the dark.
Amethystine pythons can grow to impressive sizes, with some individuals reaching over 26 feet (8 meters) in length. However, most amethystine pythons are typically between 10 and 16 feet (3 and 5 meters) long. While they are the largest native snake species in Australia, they are smaller than the Australian scrub python, which has been recorded at lengths of up to 7.2 meters (24 feet). Nevertheless, the considerable size of amethystine pythons makes them formidable predators in their natural habitats.

Australian scrub pythons are also among the largest
The Amethystine python is considered Australia's largest native snake species. However, Australian scrub pythons are also among the largest. They are commonly considered arboreal or tree-dwelling, making them one of the world's largest and longest arboreal snake species. This snake species has an ornate dorsal pattern consisting of browns and tans, with many different natural variations, and an iridescent sheen. Its belly is usually white, sometimes with some yellow. The top of the head is covered with large symmetrical shields, and there are heat-sensing pits on the rostral and some labials.
The Australian scrub python is a rare species outside of Australia, but captive breeding projects and hobbyists interested in the species have made it more available. A female scrub python measuring 4.33 m (14.2 ft) long and weighing 13.5 kg (30 lb) was documented to have swallowed a 10 kg (22 lb) adult mobile wallaby. The largest female scrub python ever seriously measured was captured in Palm Cove near Cairns in 2000. It had a total length (including tail) of 5.65 m (18.5 ft), a head length of 12 cm (4.7 in), a tail length of 75 cm (30 in), a midbody circumference of 36 cm (14 in), and a weight of 24 kg (53 lb).
The largest male scrub python on record was discovered in Kuranda in 2002, with a length of 5.33 m (17.5 ft), a head length of 11 cm (4.3 in), a tail length of 60 cm (24 in), and a weight of 19 kg (42 lb). However, heavier males have been measured, some weighing more than 27 kg (60 lb) with a length of more than 5 m (16 ft). An extremely large specimen from Barron Falls in 1954 measured 7.2 m (24 ft) but consisted of an artificially stretched frame.
The Australian scrub python exhibits an unusual sexual dimorphism among pythons, with males typically being a third longer and twice as heavy as females. Females reach sexual maturity with a snout-to-vent length (SVL) of about 2.27 m (7.4 ft), while males reach sexual maturity with an SVL of 1.34 m (4.4 ft). On the Tully River, about 140 km south of Cairns, 24 adult females were measured, with an average SVL of 2.68 m (8.8 ft) and a mass of 3.4 kg (7.5 lb).
