Adder or Viper - Vipera Berus

Ange Boyson (July)

We saw this Adder just on the forest track by Plas y Brenin.

Also known as 'Vipers' Adders are active during the day, spending time basking in the sun until their body temperature is high enough to hunt for food. This is probably what this Adder was doing when we disturbed it.

The Adder is recognisable by the bold zigzag stripe down its back and a distinctive inverted V shape on the back of the head.

They are BritainâÂ.Â.s only venomous reptile but are not aggressive snakes and will only attack if harassed or threatened. Although an AdderâÂ.Â.s bite is not lethal, the bite is very painful and requires urgent medical attention. There have only been 10 recorded deaths from their bite in the last 100 years. With proper treatment, the worst effects are nausea and drowsiness, followed by severe swelling and bruising in the area of the bite. It's worth noting that most people who are bitten by an adder were handling the snake at the time. So it's best to treat adders with respect and leave them alone.
