Vipera berus, commonly known as the common European adder and the common European viper, is a species of venomous snake in the family Viperidae. The species is extremely widespread, and thus can be found throughout much of Europe, and as far as East Asia. There are three recognised subspecies. Known by a host of common names including common adder and common viper, the adder has been the subject of much folklore in Britain and other European countries. It is not regarded as especially dangerous; the snake is not aggressive and usually bites only when really provoked, stepped on, or picked up. Bites can be very painful, but are rarely fatal.
