Popular snake species

The only snake to occur within the Arctic Circle, the adder has the widest global distribution of all terrestrial snakes. Although famous for its venomous bite, the adder is actually a shy, non-aggressive species which will only strike when it feels threatened.

Rather than laying eggs, the adder is viviparous, giving birth to between 3 and 18 live young once every 2 years. Adders hibernate over winter, usually returning to the same site each year throughout their lives.
