Key identifying features
The Jayapura green tree python is a locality form of Morelia viridis collected from the area around Jayapura, the capital of West Papua, near the border with Papua New Guinea. It displays the universal green tree python body plan: laterally compressed sides, a strongly prehensile tail, and the characteristic coiled resting posture draped over a branch with the head centered in the coils.
Coloration & pattern
Adults typically show a bright to medium green dorsal color with moderate scattered blue speckling, which can appear as individual flecks or small clusters along the back. The belly is pale yellow to white. As in all green tree pythons, hatchlings emerge in a vivid yellow or red juvenile phase and gradually convert to green over the first one to two years of life, a hallmark trait of the species used to distinguish it from most other pythons at any age.
Head, eyes & scales
The head is large and triangular, clearly offset from a narrower neck, with heat-sensing pits along the labial scales used to detect warm prey in low light. The eyes are large, dark, and have vertical pupils. Scales are small and smooth, contributing to the glossy sheen typical of the species.
Size & body shape
Adults commonly reach 4 to 6 feet, with a slender, laterally flattened body and a strongly prehensile tail. Females are generally larger and heavier-bodied than males.
Range & habitat where you'll see it
This locality form originates from lowland rainforest around Jayapura on the northeastern coast of West Papua. It occupies the forest canopy and understory shrub layer, rarely descending to the ground except to move between perches.
How to tell it apart from look-alikes
Jayapura individuals generally fall within the typical range of green and blue patterning seen across New Guinea localities, making positive identification without confirmed collection data difficult; keepers rely on subtle differences in flecking density and hue that overlap between populations. Green tree pythons overall are distinguished from the unrelated emerald tree boa by their New Guinea/northern Australia range and different head scale and heat-pit arrangement, and from carpet pythons by their solid green adult coloration rather than a blotched pattern.
