The adder or viper is the only poisonous snake found in Great Britain. It does not occur in Ireland, although it is widespread on the Continent. It varies a good deal in colour, but the typical specimen is grey-buff with a dark diamond pattern down the spine. It is an inoffensive creature and does not attack if left alone. Its bite is not dangerous to a healthy person, though by no means a thing to trifle with. It can be fatal to dogs and sheep. An average adder is 20 ins. or a little more in length. Its favourite haunts are moors and heaths. |
