Dendrelaphis punctulatus, also known commonly as the Australian tree snake, the common tree snake, and the green tree snake, is a species of slender, large-eyed, diurnal, non-venomous snake in the family Colubridae. The species is native to many parts of Australia, especially in the northern and eastern coastal areas, and to Papua New Guinea. It is an agile snake with a very slender body and tail and is also a strong swimmer, using the water for hunting and avoiding predation. The ventral body colour varies from golden yellow, to bright green, to olive-green, to black, sometimes even blue, while its back is typically dark in colour. It is frequently pale yellow on the throat and belly, but other pale colours have been noted. Blue flecks are present on the flanks. Wikipedia →
