The green tree python ('Morelia Viridis') is a species of snake in the family "Pythonidae". The species is native to New Guinea, some islands in Indonesia, and the Cape York Peninsula in Australia. As its common name suggests, it is a bright green snake that can reach a total length (including tail) of 2 m (6.6 ft) and a weight of 1.6 kg (3.5 lb), with females slightly larger and heavier than males. Living generally in trees, the green tree python mainly hunts and eats small reptiles and mammals.

Newborn green tree pythons are bright yellow. orange, or brick red and do not develop green coloring for 6-8 months. These pythons lure their food by sitting very still on a branch and dangling their tail. Curious about the wiggling tail, the prey gets close enough for a strike. Green tree pythons spend much of their time coiled around branches, situated so that their head lies right in the middle of their coils, similar to a saddle laying over a branch.

The green tree python is often bred and kept in captivity, although it is usually considered an advanced species due to its specific care requirements and generally irritable temperament. It is a popular species among reptile enthusiasts and breeders on account of its adult and juvenile colours. This has led to large numbers being illegally caught in the wild to the detriment of native populations.
