The smooth green snake 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 36–51 cm (14–20 in) 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.
Imantodes cenchoa, also known commonly as the blunthead tree snake, the neotropical blunt-headed tree snake, and the fiddle-string snake, is a species of mildly venomous, rear-fanged snake in the family Colubridae. The species is native to Mexico, Central America, and South America.
Boiga forsteni, also known commonly as Forsten's cat snake, is a species of mildly venomous rear-fanged snake in the family Colubridae. The species is endemic to South Asia.
Elaphe hodgsoni, also known commonly as Hodgson's rat snake and the Himalayan trinket snake, is a species of snake in the family Colubridae. The species is native to parts of Asia around the Himalayas.
Ptyas mucosa, commonly known as the Oriental rat snake, dhaman or Indian rat snake, is a common non-venomous species of colubrid snake found in parts of South and Southeast Asia. Dhamans are large snakes. Typical mature total length is around 1.5 to 1.95 m though some exceed 2 m. The record length for this species was 3.7 m, second only to their cousin Ptyas carinata among living colubrid snakes. Despite their large size, oriental ratsnakes are usually quite slender with even a specimen of 2 m commonly measuring 4 to 6 cm only around in diameter. Furthermore, the average weight of ratsnakes caught in Java was around 877 to 940 g, though larger males of over 2.3 m may easily weigh over 2.5 kg (5.5 lb). Their color varies from pale browns in dry regions to nearly black in moist forest areas. Rat snakes are diurnal, semi-arboreal, non-venomous, and fast-moving. Rat snakes eat a variety of prey and are frequently found in urban areas where rodents thrive.
Diadophis punctatus, commonly known as the ring-necked snake or ringneck snake, is a rather small, harmless species of colubrid snake found throughout much of the United States, as well as south in Central Mexico and as far north as Quebec, Canada. Ring-necked snakes are generally fossorial and somewhat secretive, by nature, and, as a nocturnal species, are rarely seen during the daytime. These snakes are believed to be fairly abundant throughout most of their range, though no scientific evaluation supports this hypothesis. Scientific research is lacking for the species, despite their apparently common status, and more in-depth investigations are greatly needed. It is the only species within the genus Diadophis and, currently, 14 subspecies are identified, though many herpetologists question the morphologically-based classifications.
The eastern racer, or North American racer, is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America and Central America. Eleven subspecies, including the nominotypical subspecies, are recognized, which as a group are commonly referred to as the eastern racers. The species is monotypic in the genus Coluber.
