Britain's only venomous snake, adders are
usually very shy - they rarely attack, and spend the
winter in hibernation.
Habitat – Found throughout Wales, adders are
more common on the coast, inland heath and commons. They’re very
shy, but are most easily seen in early spring after
Appearance – A dark zigzag along its back
contrast nicely with the grey colouration of the male but less well
with the browny-red of the female.
Young – Born during early summer, they have to
quickly find enough food to keep them going through
What about its bite? It’s very unusual for
adders to bite people or pets – they only attack if they’re picked
up or accidentally sat or trodden on. If an adder does bite you,
stay calm and seek medical attention as soon as possible.
