The viperine watersnake is the most viper-like of the European watersnakes, both in looks and behaviour, and it is frequently killed by  persons who confuse it with a venomous snake. I have since found specimens in Portugal in even cold mountain streams so it appears to be plentiful. I once taught a female traveling companion to catch snakes and she brought me 13 viperine watersnakes in under one hour. I had to ask her to stop.
