Opheodrys
''Opheodrys'' is a genus of small to medium-sized nonvenomous colubrid snakes commonly referred to as green snakes. In North America the genus consists of two distinct species. As their common names imply, the rough green snake has keeled dorsal scales, whereas the smooth green snake has smooth dorsal scales. Species Valid species The following two species are recognized as being valid. *''Opheodrys aestivus'' (Linnaeus, 1766) – rough green snake *''Opheodrys vernalis'' ( Harlan, 1827) – smooth green snake ''Nota bene'': A binomial authority in parentheses indicates that the species was originally described in a genus other than ''Opheodrys''. Species removed from the genus The genus ''Opheodrys'' at one time included two Asian species: ''O. herminae'', which is endemic to Japan, and ''O. major'', which is endemic to Central/South China, Taiwan, N. Vietnam, and Laos. These were removed from the genus by Cundall in 1981 *''Opheodrys herminae'' ( Boettger, 1895) = '' Pty ...

Opheodrys Aestivus
''Opheodrys aestivus'', commonly known as the rough green snake, is a venom (poison), nonvenomous North American Colubridae, 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 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. Description 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 in total length (including tail) and is very thin. Etymology The specific name, ''aestivus'', is Latin for "summer" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smooth Green Snake
The smooth green snake (''Opheodrys vernalis'') is a species of North American nonvenomous snake in the family Colubridae. The species is also referred to as the grass snake. It is a slender, "small medium" snake that measures as an adult. It gets its common name from its smooth dorsal scales, as opposed to the rough green snake, which has keeled dorsal scales. The smooth green snake is found in marshes, meadows, open woods, and along stream edges, and is native to regions of Canada, the United States, and northern Mexico. A non-aggressive snake, it seldom bites and usually flees when threatened. It mates in late spring to summer, and females lay their eggs from June to September. The smooth green snake will often bob its head in order to mimic vegetation blowing in the wind. Description The smooth green snake is slender. In size, it is classified as a "small medium" snake, reaching to in total length (including tail) as an adult. The longest smooth green snake was measured as ...

Colubrid
Colubridae (, commonly known as colubrids , from , 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest fossil species of the family date back to the Late Eocene epoch, with earlier origins suspected. Colubrid snakes are found on every continent except Antarctica. Description Colubrids are a very diverse group of snakes. They can exhibit many different body styles, body sizes, colors, and patterns. They can also live in many different types of habitats including aquatic, terrestrial, semi-arboreal, arboreal, desert, mountainous forests, semi-fossorial, and brackish waters. A primarily shy and harmless group of snakes, the vast majority of colubrids are not venomous, nor do most colubrids produce venom that is medically significant to mammals. However, the bites of some can escalate quickly to emergency situations. Furthermore, within the Colubridae, the South African boomslang and twig snakes, as well as the Asian keelback snakes ('' R ...

Greater Green Snake
