Simalia amethistina, commonly known as the Amethystine Python, is native to the rainforests and tropical regions of Australia and New Guinea. It is one of the largest python species, with iridescent scales that shimmer in sunlight. This nocturnal predator primarily feeds on birds and mammals, playing a crucial role in controlling their populations.

Simalia amethistina, commonly known as the Amethystine Python or Scrub Python, is native to Indonesia, Papua New Guinea, and Australia. In Australia, it is primarily found in the northeastern parts, specifically in Queensland.

The Amethystine Python inhabits tropical and subtropical rainforests, savanna woodlands, and mangroves. It prefers warm, humid environments typically found in these regions, with temperatures ranging from 24°C to 30°C (75°F to 86°F) and high levels of humidity.

As a large constrictor, the Amethystine Python occupies a predatory niche within its environment. It primarily preys on small mammals, birds, and occasionally other reptiles. This species is arboreal and terrestrial, often found in trees but also on the ground, which allows it to exploit a variety of prey and habitats effectively. Adaptations such as its cryptic coloration help it blend into the forest canopy and underbrush, aiding in both predation and avoiding detection by predators.
