What is an "adder"?

An adder is a venomous snake found in various parts of Europe and Asia. It is a relatively small snake with a distinctive dark zigzag pattern along its back. The coloration of the adder can vary, ranging from gray or brown to reddish-brown. It is a terrestrial snake that inhabits a variety of habitats, including grasslands, woodlands, and rocky areas. The adder is known for its venomous bite, although it is generally not aggressive and will typically only bite if threatened or provoked. Its venom is primarily used to immobilize and subdue prey, consisting of small mammals, birds, and lizards. The adder plays an important role in its ecosystem as both a predator and prey, and it is an integral part of the natural biodiversity in its range.
