Grass Snake Natrix helvetica

Grass snakes are found throughout England and Wales. They feed primarily on fish and amphibians, and can occasionally venture into garden ponds in the summer months. Grass snakes are non-venomous and are extremely timid, moving off quickly when disturbed. If cornered they can feign death, and if handled frequently, produce a foul-smelling excretion. Image: Neil Rolph (Flickr).
