Common Tree Snake

Brief Description

A slender, agile, and harmless colubrid snake native to Australia and New Guinea, often found in trees and near water.

Characteristics

Slender body, large distinctive eyes, and a very long tail. Colouration is variable, often olive-green, brown, or blackish on the back with a yellowish belly. Scales can have bluish or dark edging, particularly when the skin is stretched.

Habitat

Found in a variety of habitats ranging from tropical rainforests and wet sclerophyll forests to urban gardens and wetlands in coastal and sub-coastal eastern Australia.

When to Find It

Active during the day (diurnal) throughout the warmer spring and summer months, becoming less active during cooler winter periods.

Conservation Status

Least Concern

Ecological Role

Acts as an important predator of frogs, small lizards, and occasionally fish, helping to regulate prey populations in wetland and forest ecosystems.

Easily Confused With

Can be confused with venomous species such as juvenile elapids, but is easily distinguished by its very slender build, large prominent eyes, and non-venomous characteristics.

Observation Tips

Look for them basking on low branches, near water bodies, or moving rapidly through vegetation during warm daytime hours.

Interesting Facts

Common Tree Snakes are exceptionally agile climbers and swimmers, and they rely heavily on their excellent eyesight to hunt agile prey like tree frogs.
