Key identifying features
The Amethystine Python is a very large snake, commonly reaching 10 to 16 feet or more, among the longest pythons found in Australia and New Guinea. Its most notable identifying trait is the strong iridescent, amethyst-like sheen on its scales, which produces shifting purple, green, and blue highlights in direct light, especially noticeable against its olive-brown to tan base color.
Coloration & pattern
The body is generally olive-brown, tan, or yellowish-brown, marked with faint, irregular darker blotches or a subtly reticulated pattern that can be difficult to see except in good lighting due to the strong iridescence of the scales. The overall impression is of a relatively plain-colored but highly glossy snake rather than one with bold contrasting markings.
Head, eyes & scales
The head is elongated and moderately distinct from the neck, with prominent heat-sensing pits along the lips used to detect warm-bodied prey. Eyes have vertically elliptical pupils. Scales are smooth and strongly iridescent, especially along the back.
Size & body shape
This is an exceptionally long, powerfully muscled python, generally more elongated relative to its girth compared to some other giant pythons, though still capable of considerable bulk in large adults. Juveniles show a similar coloration and pattern to adults, though the iridescence may be less pronounced at hatching.
Range & habitat where you'll see it
The Amethystine Python is found in northeastern Australia, particularly parts of Queensland, as well as New Guinea and nearby islands, inhabiting rainforests, woodlands, and rocky areas, often climbing into trees or sheltering in caves and rock crevices.
How to tell it apart from look-alikes
Its great length and strong iridescent sheen distinguish it from the more boldly and distinctly patterned carpet pythons found in overlapping parts of its range, which typically show clearer, more contrasting blotches or bands rather than the Amethystine's subtler, glossier appearance. Its size alone, often far exceeding that of other Australian pythons, is a useful clue, as few other species in the region approach its typical adult length.
Frequently asked questions
How large does the Amethystine Python get?
It commonly reaches 10 to 16 feet or more, making it one of the largest pythons in the world and the longest snake in Australia.
What gives the Amethystine Python its name?
Its scales have a strong iridescent, amethyst-like sheen that produces shifting purple, green, and blue highlights in good light.
Where does the Amethystine Python live?
It is found in rainforests and woodlands of northeastern Queensland, Australia, as well as New Guinea and nearby islands.
How does its pattern compare to a carpet python's?
The Amethystine Python has a subtler, less boldly blotched pattern, relying more on its glossy iridescence than strong contrast, unlike the more distinctly marked carpet python.
