Opheodrys aestivus, commonly known as the rough green snake, is a nonvenomous North American colubrid. It 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 unrelated. The rough green snake is docile, often allowing close approach by humans, and seldom bites. Even when bites occur, they have no venom and are harmless.
The rough green snake (Opheodrys aestivus) is bright green above and has a yellowish belly, affording it excellent camouflage in green vegetation and making them difficult to see in the wild even though they are relatively common in their habitat. It has keeled dorsal scales, which are arranged in 17 rows at mid-body. It grows up to 116 cm (45+3⁄4 in) in total length (including tail)[3] and is very thin.
Predators of the rough green snake include birds and other snakes, such as the eastern racer (Coluber constrictor) and the eastern king snake (Lampropeltis getula).

ReproductionEdit
The rough green snake breeds in spring, and sometimes again in fall. Females lay 2-14 eggs, occasionally in a communal nest shared by more than one female. Up to 75 eggs have been found in one such nest. The nest site varies: under boards, under bark in rotting stumps, in deep mulch, or under a rock. Hatchlings from spring breeding typically emerge in August or September, and each is about 18–20 cm (7.1–7.9 in) in total length.
