The Grass Snake (Natrix natrix) is the best known european snake. It is widespread throughout Europe and occurs from England to Russia, from Spain to Finland. The specimen shown here was found laying in the shallow water of a large bohemian pond. Only decades ago, this reptile was very common, especially in habitats associated with water. But in our days such natural habitats are rare, at least in congested urban areas. Gras snakes feed on amphibians, fish, small mammals and, to a lesser degree, on young birds. Mature females can be up to 200 cm long, but usually reach a length of 100 - 150 cm. The males are smaller. The typical characteristic of central european subspecies is the yellowish or white 'half-moon' on both sides of the neck. The body colouration is variable, most specimens are grey or olive green with dark spots or bars along their sides. Needless to say that N. natrix is harmless. |
