5. Common tree snakes (Dednrelaphis punctulata)
Although there are 40 species of tree snakes (Dendrelaphis genus), widely spread throughout southeastern Asia and Australia, we have chosen the common tree snake as the representative, because some of the tree snakes are venomous (like brown tree snake for example). This kind of tree snakes inhabits Australia and Papua New Guinea. Common tree snake is also known as a green snake, yellow-bellied black snake or grass snake. These are very slender yet long snakes, with the average body length of 3,9 feet. They inhabit various environments, like forests and rainforests, but also dry woodland and urban areas.
