The Common Grass Snake (Natrix natrix) is a non-venomous snake found across Europe and parts of Asia. It typically inhabits wetlands, grasslands, and woodlands, where it can easily find its prey, which mainly consists of amphibians like frogs and toads. This snake can grow up to 1 meter in length and is often recognized by its olive-green or brown coloration, along with a distinctive yellow or white collar behind its head. Grass snakes are excellent swimmers and are often seen near water bodies. They are known for their ability to mimic the behavior of venomous snakes when threatened, such as flattening their necks and hissing. During the breeding season, females lay eggs in warm, damp places, and the young snakes are independent from birth.
