Key identifying features
The Palmerston carpet python is a regional form of the carpet python complex (Morelia spilota) associated with the area around Palmerston and Darwin in Australia's Northern Territory. It shares the general carpet python build: a robust, muscular body, broad triangular head distinct from the neck, and an irregular blotched dorsal pattern.
Coloration & pattern
The background color is typically olive, brown, or grayish-brown, overlaid with dark brown to black irregular blotches that often show good contrast against the base color. Pattern can appear somewhat variable, ranging from more solidly blotched to broken, blockier markings along the length of the body. The venter is pale cream to white.
Head, eyes & scales
The head is broad and triangular, clearly offset from the neck, often marked with a dark eye stripe. Heat-sensing pits line the upper labial scales. Eyes have vertical pupils suited to nocturnal and crepuscular hunting. Scales are smooth, giving the body a glossy appearance.
Size & body shape
Adults are robust and muscular, commonly reaching 6 to 8 feet in length. The body is thick and powerful, reflecting a lifestyle that includes both ground activity and climbing, unlike the more slender, laterally compressed arboreal green tree python.
Range & habitat where you'll see it
This form occurs in the Top End region of the Northern Territory, Australia, around Darwin and Palmerston, in monsoonal woodland, forest edges, and areas near human habitation where it may shelter in roof spaces or under structures.
How to tell it apart from look-alikes
The Palmerston carpet python can be told apart from the Cape York carpet python by its typically darker, more olive-brown background tone versus the paler golden-cream of Cape York individuals, though the two forms show regional overlap. It is distinguished from green tree pythons by its blotched rather than uniform pattern and heavier body build.
