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) = ''Ptya ...

Rough Green Snake
''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. 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. Geographic range The rough green snake ranges throughout the Southeastern United States, from Florida, ... [...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. Smooth green snakes will often bob their heads 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 la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Greater Green Snake
The greater green snake or Chinese green snake (''Ptyas major'') is a snake of the family Colubridae. Distribution This species can be found in Central/South China (Hainan, Henan, Gansu, Anhui, Sichuan, Fujian, Guangdong, Guangxi, Guizhou, Hunan, Hubei, Jiangxi, Jiangsu, Shaanxi, Zhejiang) and Hong Kong, in Taiwan, North Vietnam, Laos and Bangladesh (Sylhet, Ratargul Swamp Forest). Habits and habitat This snake is diurnal and semi-arboreal, living in humid forests and farmland. When encountered, they are mild-mannered and rarely bite. Description ''Ptyas major'' is a slender, medium-sized snake, averaging 75–90 cm (2½-3 feet) in total length, but occasionally growing to 120 cm (4 feet). Bright green above; ventral scales greenish-yellow. Dorsal scales smooth except that males have several mid-dorsal scale rows keeled. Some specimens have scattered black spots on dorsum. Dead specimens often turn bluish. Diet Earthworms, insect larvae, and other soft-bodied inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sakashima Green Snake
The Sakishima green snake (''Ptyas herminae'') is a species of snake in the family Colubridae. The species is endemic to the Yaeyama Islands in the southern Ryukyu Islands of Japan.

Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...
