　　The adder(蝰蛇)is the only poisonous snake native to Britain.Adders have the most highly developed poison injecting mechanism of all snakes,but they are not aggressive animals.Adders will only use their poison as a last means of defence,usually if caught or trodden on.No one has died from adder bites in Britain for over 20 years.By far the most common snake in Britain is the adder.In Scotland,in fact,there are no other snakes at all.The adder is also the only British snake with a poisonous bite.It can be found almost anywhere,but prefers sunny hillsides and rough open country,including high ground.In Ireland there are no snakes at all.

　　Most people regard snake bites as a fatal misfortune,but not all bites are serious,and very few are fatal.Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself,with amateurs heroically,but mistakenly,trying do-it-yourself surgery and other unnecessary measures.

　　All snakes have small teeth,so it follows that all snakes can bite,but only the bite of the adder presents any danger.British snakes are shy animals and are far more frightened of you than you could possibly be of them.The adder will attack only if it feels threatened,as can happen if you take it by surprise and step on it accidentally,or if you try to catch it or pick it up,which it dislikes intensely.If it hears you coming,it will normally get out of the way as quickly as it can,but adders cannot move very rapidly and may attack before moving if you are very close.
