The White-Lipped Python (Bothrochilus/Leiopython albertisii complex) is a large, slender-bodied python best identified by the striking bright white or cream scales lining its upper and lower lips, which stand out sharply against its dark body. This clean white lip coloration is the species' most distinctive and reliable field mark.
Coloration & pattern
The body is typically glossy black, dark brown, or dark grey, often appearing almost uniformly dark along its length, though some individuals may show a subtle iridescent sheen in bright light. The stark white or cream lip scales create a bold contrast against this dark coloration, forming a clear pale line along the edge of the jaw. The belly is generally pale, cream to white, sometimes with irregular dark blotching.
Head, eyes & scales
The head is elongated and moderately distinct from the neck, with prominent heat-sensing pits along the lips associated with the white lip scales. Eyes are moderate in size with vertically elliptical pupils. Scales are smooth and glossy across most of the body.
Size & body shape
The White-Lipped Python is a large, slender to moderately built python, capable of reaching upward of 2 to 2.5 meters in length. Its body is more elongated and less heavy-set than some other large pythons, reflecting an active, semi-arboreal lifestyle.
Range & habitat where you'll see it
This species is native to New Guinea and nearby islands, inhabiting lowland rainforests, forest edges, and areas near water. It is known to shelter in burrows, hollow logs, and dense vegetation, and is often active at night.
How to tell it apart from look-alikes
The bright white lip scales sharply bordering a dark body are the clearest way to distinguish the White-Lipped Python from other dark-bodied pythons in New Guinea, most of which lack such a strongly contrasting pale lip line. This feature, combined with its elongated, slender build, makes for confident identification even at a glance.
