The Northern Tree Snake (Dendrelaphis calligastra) also called beautiful-bellied tree snake is a slender, large-eyed, nonvenomous, diurnal snake from Australia.
It grows up to 1.2 m in length and is greenish, brown, or greyish above with a cream or yellow belly. They often bask in the leaf canopy of small bushes and trees and can escape very quickly through it.
Its main diet consists of frogs and other reptiles. Females lay eggs in clutches from five to seven, with one female recorded as laying 11 eggs in January.
