Geographic range edit

Found in New Guinea (Western New Guinea and Papua New Guinea) and Australia in northwestern Western Australia and in the northern portion of the Northern Territory. The type locality given is "North Australia: Port Essington" (Northern Territory, Australia).[3]

Feeding edit

The snake is not venomous and kills prey by constriction. Their diet is varied and includes many different birds and mammals. Populations that inhabit forested areas are mostly arboreal and often feed on brush-tailed possums, Trichosurus.[2]

Reproduction edit

Oviparous, females deposit their eggs in secluded places such as hollow logs and tree boles where they protect and incubate them. Captive specimens have produced up to 18 eggs that hatch after a 40-day incubation period. The hatchlings are about 12 inches (30 cm) in length.[2]
