Is the rough green snake poisonous?

The rough green snake is a non-venomous colubrid snake found in many places in North America.

​These snakes occur widely in the eastern and southeastern United States, from southern New Jersey and Indiana south along the East Coast to Florida and west to central Texas, eastern Kansas and central Oklahoma.

The rough green snake can be found in the Mexican states of Tamaulipas and eastern Nuevo León. They inhabit a variety of habitats but are found in moist meadows, most often, woodlands and forests close to water along the borders of rivers and wetlands.

Though commonly present in the Piedmont and Atlantic coastal plain the species is absent from the higher elevations of the Appalachian Mountains. A small population was observed in New Mexico.

Even though they are definitely highly arboreal snakes they’re also often found on the ground, frequently foraging in thick vegetation along shorelines during the day. During the night that they may be observed sleeping tangles.

The rough green snake is really a rather long species, attaining so long as 46 inches (116 cm), although the average duration is approximately 20 to 32 inches (50 to 81 cm). They are slender typically just 1 inch or even less in diameter. Their body is a uniform while the belly, chin, and labial scales are both either cream, yellow or whitish.

Since they spend much of the life going through vegetation, this coloration forms an great camouflage from the green vegetation.​ When they die their bright green color that is typical fades to a colour and specimens may look like a racer.

Girls are slightly larger than males and juvenile rough green snake looks adult specimens except for their paler appearance. Like their name suggests that they have keeled scales. They have quite large eyes compared with to their general size.

Rough green bees are docile and seldom bite, when encountered by individuals they often suspend allowing for a close approach. They are harmless to people and don’t have any venom even if they do bite.​

The rough green snake has an average lifespan of five years in the wild, but they are able to reach around 8 decades.

These snakes fall prey to a lot of predators including bigger snakes such as black racers or king snakes, birds, cats, domestic cats, as well as spiders.

They’re also known by many other common names green whip snake, crab snake, green summertime storm, green tree snake, huckleberry snake, keel-scaled green snake, magnolia shrub and blossom snake.​

The species also shares common names like grass green or snake grass snake using their own American comparative the smooth green snake (Opheodrys vernalis). The colubrid species commonly called grass snake (Natrix natrix) located in Europe is completely irrelevant.

All these non-venomous snakes don’t constrict their prey that they simply catch it with their small recurved teeth then swallow it living. They search in shrubs and trees with their exceptional vision to discover and track prey down.


The rough green snake breeding period happens in spring, however occasionally they breed in the fall. All these snakes are oviparous, meaning feminine snakes lay eggs. The females lay two to 12 really elongated eggs in mid to late summer, during June or July

The eggs have been laid in moist areas usually at a stump or rotting log, under bark, heavy mulch, beneath a rock or tree hollow. They use a nest shared by numerous femalesup to 75 eggs are discovered these nests.

The hatchlings are born in August or September, after an incubation period of 6 to 12 weeks and are around 6 to 8 inches (15–20 cm) long. At first, the snakes are invited to light green in colour, only later do they receive their colour that is bright that is characteristic.

The rough green snake males reach sexual maturity at 21 months while females desire from 21 to 33 months.


In general, the rough green snake has no significant threats and is deemed widespread. The species is listed as”Least Concern” by the IUCN due to their large and probably relatively stable population size.

But with urban growth leading to the clearing of coastal wetlands and vegetation near deserts and aquatic habitats may have a negative effect on their amounts at least locally. Another threat is the use of pesticides within their habitats, since they eat insects because they might be prone to poisoning.

Most are victims of road kill. The rough green snake can be one of the most hundreds are collected because of their cheap price.

These snakes are likely effectively shielded in the USA national parks and wildlife refuges. More information is needed about threats, biology, range, and the species population.
