How to Identify the New Guinea Carpet Python (Identification Guide)
The New Guinea carpet python is identified by its variable but generally darker, more richly patterned blotched coloring compared to Australian carpet pythons, along with a robust, muscular build.

Key identifying features
The New Guinea carpet python is a form within the carpet python complex (Morelia spilota) native to southern New Guinea, closely related to and overlapping in range with populations found in northern Australia. It shows the standard carpet python build: a heavy, muscular body, a broad triangular head clearly set off from the neck, and an irregular blotched dorsal pattern.
Coloration & pattern
The background color ranges from tan and olive to darker brown, overlaid with irregular dark brown to blackish blotches that can appear dense and richly patterned, sometimes giving a busier, more mottled look than some Australian carpet python forms. The belly is pale cream to white, occasionally with light dark speckling.
Head, eyes & scales
The head is broad and triangular, distinct from the neck, often marked with a dark eye stripe. Heat-sensing pits line the upper labial scales. Eyes have vertical pupils, reflecting a largely nocturnal and crepuscular activity pattern. Scales are smooth, giving the body a glossy sheen.
Size & body shape
Adults are robust and muscular, typically reaching 6 to 8 feet, with a thick body relative to length that reflects a semi-arboreal, semi-terrestrial lifestyle rather than the specialized arboreal build of the green tree python.
Range & habitat where you'll see it
This form occurs in southern New Guinea, an area that connects biogeographically with the carpet python populations of northern Australia across the Torres Strait land bridge region. It inhabits a mix of forest, woodland, and grassland edge habitats.
How to tell it apart from look-alikes
The New Guinea carpet python overlaps closely with nearby Australian carpet python forms such as the Cape York and Top End populations, given the shared biogeographic history of southern New Guinea and northern Australia, and separating them reliably requires confirmed locality data rather than pattern alone. It is distinguished from the green tree python by its blotched rather than uniform green pattern and its heavier body build.
Frequently asked questions
How is the New Guinea carpet python related to Australian carpet pythons?
It belongs to the same species complex and is closely related to northern Australian populations, reflecting the historical land connection between New Guinea and Australia.
What does its pattern look like?
Irregular dark brown to blackish blotches on a tan to olive-brown background, sometimes appearing dense and richly mottled.
Is it venomous?
No, it is a non-venomous constrictor.
How does it differ from the green tree python?
It has a blotched pattern and heavier body rather than the uniform green color and laterally compressed build of the green tree python.
