Vipera berus
Common & widespread in Britain between April-September.
They are our only venomous Snake in the country.
Also known as Vipers.
The head is fairly large and distinct and its sides are almost flat and vertical.
The edge of the snout is usually raised into a low ridge.
The eye is relatively large, equal in size to or slightly larger than the nasal scale, but often smaller in Females.
Females are typically brown with dark brown markings, whereas males are a uniform grey with black markings.
The base colour of Males is often slightly lighter than that of Females, which makes the black zigzag pattern stand out more.
