Dendrelaphis calligaster, also called green tree snake and northern tree snake, is a colubrid snake native to Indonesia, Papua New Guinea and Australia. [1] It is a slender, large-eyed, non-venomous, diurnal snake, which grows up to 1.2 m in length and is greenish, brown, or greyish above with a cream or yellow belly. [2]

Contents

This common snake is harmless, and readily recognised due to its cream to yellow belly and pronounced wide dark facial stripe passing across the eye. [2] [3]

Etymology

Dendrelaphis: 'tree Elaphe', after another genus of colubrid snakes. calligaster: 'beautiful-bellied'. [4]

Distribution and habitat

Northern tree snakes are found in tropical north Queensland, from Paluma to Cooktown and eastern Cape York Peninsula, as well as southern Papua New Guinea. They live in a wide variety of habitats, including rainforest, urban and farmed regions, and open forest. They often bask in the leaf canopy of small bushes and trees and can escape very quickly through the canopy.[ citation needed ]

Behaviour and ecology

They eat frogs and reptiles.[ citation needed ]

Breeding

The northern tree snake lays five to seven eggs in clutches, with one female recorded as laying 11 eggs in January. [3]

The Australian water dragon, which includes the eastern water dragon and the Gippsland water dragon subspecies, is an arboreal agamid species native to eastern Australia from Victoria northwards to Queensland. There may be a small introduced population on the south-east coast of South Australia. The Gippsland Water Dragon is generally the more southern of the two species and the more cold adapted and heat sensitive. Visually distinguishing the Gippsland Water Dragon from the Eastern Water Dragon is relatively easy, as long as their skin is reasonably clean and not stained from the water, as identification of the two subspecies depends largely on observable differences in colours and patterns.
