Re.22. NATRIX(Water Snakes)

 

Phylum  : Chordata

Class   : Reptilia

Order  : Squamata

Family : Colubridae

Genus : Natrix

DESCRIPTION

Natrix is a genus of Old World Snakes found mainly across Eurasia (although the range of Natrix tessellata extends into Egypt and those of N. astreotophora and N. maura into north-west Africa) in the Subfamily Natricinae of the Family Colubridae. 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. The refuge of a widely distributed Western European lineage regarding the barred grass snakes commonly known as Natrix helvetica was most likely located in southern France and outside the classical refuges in the southern European peninsulas. One genetic lineage of the common grass snakes (N. natrix) is also distributed in Scandinavia, Central Europe, and the Balkan Peninsula.

IUCN Status: Least concern
