Natrix
''Natrix'' is a genus of Old World snakes found across Eurasia (although the range of ''Natrix tessellata'' extends into Egypt and those of '' N. astreptophora'' and '' N. maura'' into north-west Africa) in the subfamily Natricinae of the family Colubridae. Common names Member species of the genus ''Natrix'' are collectively called grass snakes and water snakes, but some other snake species also known commonly as "grass snakes" and "water snakes" are not in the genus. Species The genus ''Natrix'' contains five extant species and at least five extinct (fossil-only) species. ''Nota bene'': A binomial authority in parentheses indicates that the species was originally described in a genus other than ''Natrix''. Etymology ''Natrix'' is classical Latin for a water snake. The word comes from a Proto-Indo-European root meaning "snake", with cognates in the Celtic and Germanic languages, the latter including the English adder. It was probably influenced through folk etymology by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natrix Natrix
The grass snake (''Natrix natrix''), sometimes called the ringed snake or water snake, is a Eurasian non-venomous colubrid snake. It is often found near water and feeds almost exclusively on amphibians. Subspecies Many subspecies are recognized, including: ''Natrix natrix helvetica'' ( Lacépède, 1789) was formerly treated as a subspecies, but following genetic analysis it was recognised in August 2017 as a separate species, ''Natrix helvetica'', the barred grass snake. Four other subspecies were transferred from ''N. natrix'' to ''N. helvetica'', becoming ''N. helvetica cettii'', ''N. helvetica corsa'', ''N. helvetica lanzai'' and ''N. helvetica sicula''. Description The grass snake is typically dark green or brown in colour with a characteristic yellow or whitish collar behind the head, which explains the alternative name ringed snake. The colour may also range from grey to black, with darker colours being more prevalent in colder regions, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barred Grass Snake
The barred grass snake (''Natrix helvetica'') is a non-venomous colubrid snake from Western Europe, living in and close to water. It was included within the grass snake species, ''Natrix natrix'', until August 2017, when genetic analysis led to its reclassification as a separate species. Subspecies There are currently five subspecies of ''Natrix helvetica'' recognized (having been formerly classified as subspecies of '' N. natrix''): *''N. helvetica helvetica'' (syn. ''N. natrix helvetica'') *''N. helvetica cetti'' (syn. ''N. natrix cetti'') *''N. helvetica corsa'' (syn. ''N. natrix corsa'') *''N. helvetica lanzai'' (syn. ''N. natrix lanzai'') *''N. helvetica sicula'' (syn. ''N. natrix sicula'') Description The barred grass snake has a dark grey-green upper body with characteristic black barring along the flanks. The underparts are pale. It has a distinctive yellow and black collar around the neck, a feature it shares with the grass snake. It can grow to a length of over ...

Natrix Maura (cropped)
''Natrix maura'' is a natricine water snake of the genus ''Natrix''. Its common name is viperine water snake or viperine snake. Despite its common names, it is not a member of the subfamily Viperinae. This nonvenomous, semiaquatic, fish-eating snake was given its common names due to behavioural and aesthetic similarities with sympatric adder species. Behaviour The viperine snake looks like an adder and behaves like one. It is known to strike like an adder, but not bite. However, when in water, the viperine snake then looks like a grass snake and hunts its prey in the same way. This snake is diurnal. Viperine water snakes are not aggressive and rarely bite. They spend most of their time in water hunting fish, frogs and other aquatic animals. Geographic range The viperine snake is found in southwestern Europe and northwestern Africa. Specifically, ''N. maura'' is found in the European countries of: Portugal, Spain, France, northernwest Italy, and even into Switzerland. It has s ...

Natricinae
The Natricinae are a subfamily of colubroid snakes, sometimes referred to as a family (Natricidae). The subfamily comprises 37 genera. Members include many very common snake species, such as the European grass snakes, and the North American water snakes and garter snakes. Some Old World members of the subfamily are known as keelbacks, because their dorsal scales exhibit strong keeling. Natricine snakes are found in Africa, Asia, Europe, North America, and Central America as far south as Costa Rica. A single species, '' Tropidonophis mairii'', reaches Australia. Although the highest diversity is in North America, the oldest members are in Asia and Africa, suggesting an Old World origin for the group. Most species are semiaquatic and feed on fish and amphibians, although a few are semifossorial or leaf-litter snakes that feed on invertebrates. Most species are harmless to humans, but a few (e.g., ''Thamnophis sirtalis'', '' Thamnophis elegans'') are capable of inflicting bites t ...

Colubridae
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.
