The common tree snake, Dendrelaphis punctulatus, (also called green tree snake and Australian tree snake) is a slender, large-eyed, non-venomous, diurnal snake of many parts of Australia, especially in the northern and eastern coastal areas, and into Papua New Guinea. It has a primitive venom apparatus and a mildly toxic venom that is not regarded as dangerous to human beings. It's tiny grooved venom-conducting fangs are positioned week to the back of the upper jaw, meaning that it must partially swallow its prey in order to work the fangs into it.
