Common Tree Snake

Brief Description

A slender, agile, arboreal snake known for its variable coloration (often green, brown, or olive) and large eyes, commonly found hunting in trees and shrubs in tropical Australia.

Characteristics

Slender body with a distinct, broad head and large golden-brown eyes. The scales can range from olive-green to brown or blackish above, often with flecks of blue or turquoise between the scales when stretched, and a yellowish or cream belly.

Habitat

Inhabits rainforests, wet sclerophyll forests, woodlands, and urban gardens, frequently climbing in trees, bushes, and around water bodies.

When to Find It

Active throughout the year in the tropical climate of Cairns, with peak activity during the warmer spring and summer months.

Conservation Status

Least Concern

Ecological Role

Acts as an important predator of frogs, lizards, and small birds, helping to regulate prey populations in its ecosystem.

Easily Confused With

Green Tree Snake (Dendrelaphis punctulatus) is the same species. Can be casually confused with venomous species like the Rough-scaled Snake (Tropidechis carinatus) if not carefully examined, but Common Tree Snakes have large eyes, a slender non-venomous profile, and round pupils.

Observation Tips

Look for them basking on branches or moving quickly through foliage during daylight hours. Approach slowly as they are alert and quick to escape into dense cover.

Interesting Facts

Common Tree Snakes are completely non-venomous and harmless to humans. When cornered, they can inflate their bodies to show bright skin patches between their scales and release a foul-smelling musk.
