How to Identify the Cape York Carpet Python (Identification Guide)

Key identifying features

The Cape York carpet python is a regional form of the carpet python complex (Morelia spilota) found on Cape York Peninsula in far northern Queensland, Australia. It is identified by its heavily built, muscular body, a broad triangular head distinct from the neck, and a bold, irregular blotched or striped dorsal pattern typical of carpet pythons.

Coloration & pattern

The background color ranges from cream, pale gold, or olive to light brown, overlaid with irregular dark brown to blackish blotches, often with pale centers, that may connect to form broken longitudinal bands along the body. Pattern intensity and background tone vary considerably between individuals, but the blotched arrangement (rather than the uniform coloration of a green tree python) is a defining trait. The belly is typically pale cream or white, sometimes with scattered dark flecking.

Head, eyes & scales

The head is broad, triangular, and clearly set apart from the neck, often marked with a dark stripe running through the eye. Heat-sensing pits are visible along the upper labial scales. Eyes have vertical pupils, consistent with the species' largely nocturnal and crepuscular activity pattern. Scales are smooth and glossy.

Size & body shape

Cape York carpet pythons are robust, muscular snakes, with adults commonly reaching 6 to 8 feet, occasionally more. The body is thick-bodied and powerful rather than laterally compressed like the arboreal green tree python, reflecting a more generalist, semi-arboreal to terrestrial lifestyle.

Range & habitat where you'll see it

This form occurs across Cape York Peninsula in the far north of Queensland, Australia, occupying a range of habitats including rainforest margins, woodland, and rocky outcrops. It is found both on the ground and climbing into trees and shrubs, particularly around structures and rock crevices offering shelter.

How to tell it apart from look-alikes

The Cape York carpet python can be distinguished from green tree pythons by its blotched, non-uniform pattern and thicker, less laterally compressed body. Compared to other carpet python subspecies further south, such as the coastal or diamond python, Cape York individuals tend to show a paler, more golden-cream background with bolder, more contrasting dark blotches, though intergradation and regional variation blur sharp boundaries between forms.
