This non-venomous reptile thrives in a variety of habitats, including wetlands, forests, grasslands, and even gardens. Grass Snakes are typically found near water bodies such as ponds, lakes, rivers, and marshes, where they hunt for their preferred prey. Their distribution extends across Europe, from the British Isles and Scandinavia to southern Italy and the Balkans, and into parts of Asia, including western Russia and Kazakhstan.
Grass snakes are characterized by their olive-green, brown, or grayish coloration, often with a series of black vertical bars or spots along their flanks. One of the most distinctive features of the Grass Snake is the yellow or white collar around its neck, bordered by black, which gives it the name “Ringed Snake” in some regions. Their scales are smooth, giving them a sleek appearance, and their round pupils indicate their daily activity.
These snakes are primarily diurnal and are most active during the day. They are excellent swimmers and often take to the water to escape predators or to hunt for food. When threatened, Grass Snakes exhibit several defensive behaviors, including hissing, flattening their heads to appear more intimidating, and releasing a foul-smelling secretion from their anal glands. They may also play dead, a behavior known as thanatosis, where they flip onto their back and remain motionless with their mouth open. These adaptations help them avoid predation from birds of prey, mammals, and other predators.
