About the Coconut Tree Snake

Dendrelaphis calligaster, also called green tree snake, northern green tree-snake, and northern tree snake, is a colubrid snake native to New Guinea, Australia, and Solomon Islands. 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.

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. The specific name calligaster means "beautiful-bellied". In Australia, Dendrelaphis calligaster are found on the eastern side of the Cape York Peninsula (Queensland) as far south as Mackay. On the western side, their range is poorly mapped. They also occur on many of the Torres Strait Islands. On the New Guinea mainland, they are widespread at elevations below 1,150 m (3,770 ft) in both Indonesian and Papua New Guinean parts of the island. They occur also on many nearby islands. The Reptile Database also lists this species from the Solomons.

Dendrelaphis calligaster is primarily arboreal but can also forage on the ground. It can be found in rainforest... Wikipedia →
