What is the difference between a Green Tree Python and a Green Tree Snake if you have a look on wiki it seems Morelia viridis and Dendrelaphis punctulata are completely different types of snakes?

Answer 1

They're from very different groups, with many anatomical differences, most of which are very technical. Generally, boas and pythons are a group of 'primitive' snakes which retain vestiges of their hind limbs and have the ability to sense heat via lip pits, while green tree snakes lack hind limb vestiges and cannot sense heat. Pythons and boas are usually stockier and slower, but much stronger.
