Definition
An adder is a venomous snake, typically referring to the common European viper (Vipera berus). Adders are found throughout Europe and Asia. π They have a distinctive zig-zag pattern on their backs and are relatively small in size. π Adders use their venom to subdue prey such as rodents, amphibians, and birds. Think of them as the camouflaged ambush predators of the snake world, blending seamlessly into their surroundings. They are an important part of the ecosystem. While their venom is potent, adder bites are rarely fatal to humans.
