Colubrid Snake are a group of solid-toothed and rear-fanged snakes that lack a sophisticated venom-delivery system. Only ten species occur in Australia (all of which are found in Queensland) but this is the world’s most diverse and widespread snake family.

Many Australian Colubrid Snake are aquatic (feeding on fish or crabs) or semi-aquatic (for example, the Freshwater Snake, Tropidonophis mairii) preying on frogs, lizards, tadpoles and fish.

The group also includes tree snakes; slender, agile climbers that glide through the trees with ease. The Green Tree Snake (Dendrelaphis punctulata) feeds mainly on frogs and the Brown Tree Snake (Boiga irregularis) is mainly a bird-eater – notorious for its raids on aviaries.
