Opheodrys aestivus, commonly known as the rough green snake, is a species of nonvenomous North American snake in the subfamily Colubrinae of the family Colubridae. The species is sometimes called grass snake or green grass snake, but these names are more commonly applied to the smooth green snake (Opheodrys vernalis). The European colubrid called grass snake (Natrix natrix) is not closely related. The rough green snake is docile, often allowing close approach by humans, and rarely bites. Even when bites occur, they have no venom and are harmless. Wikipedia →
