Morelia viridis, the green tree python, is a species of python found in New Guinea, islands in Indonesia, and Cape York Peninsula in Australia.
Description
Adults average 120–200 cm (3.9–6.6 ft) in length, with a maximum length (although rare) of about 7 feet. The supralabial scales have thermoreceptive pits.[2]
A mostly arboreal species with a striking green or yellow color in adults, the color pattern on this species can vary dramatically from locality to locality. For example, the Aru local is a vivid green with a broken vertebral stripe of white or dull yellow scales, the Sorong local is a bright green with blue highlights and a solid vertical stripe, and the Kofiau local is mostly yellow with varying highlights in white or blue. Cyanomorphs (blue morphs) are also known to occur but are not considered common at this time.[2] Juveniles are polymorphic, occurring in reddish, bright yellow and orange morphs.
Geographic range
Found in Indonesia (Misool, Salawati, Aru Islands, Schouten Islands, most of Western New Guinea), Papua New Guinea (including nearby islands from sea level to 1,800 m elevation, Normanby Island and the d'Entrecasteaux Islands) and Australia (Queensland along the east coast of the Cape York Peninsula). The type locality given is "Aroe-eilanden" (Aru Islands, Indonesia).[1]
This species is sympatric with M. spilota and the two often compete in the same ecological niche.
Habitat
Its main habitat is in rainforests, bushes, shrubs and trees.
Conservation
The largest threat to the species is habitat destruction due to logging of forests.
Behavior
Primarily arboreal, these snakes have a particular way of resting in the branches of trees; they loop a coil or two over the branches in a saddle position and place their head in the middle. This trait is shared with the emerald tree boa, Corallus caninus, of South America. This habit, along with their appearance, has caused people to confuse the two species when seen outside their natural habitat.
Reproduction
Oviparous, with 1-25 viable eggs per clutch. In the wild eggs are incubated and protected by the female, often in the hollow of a tree. Hatchlings are lemon yellow with broken stripes and spots of purple and brown, or golden or orange/red. Over time the color changes as the animal matures, color of the adult depends on the locality of the animal (some taking many years to finish color change).
