He`s not dangerous, can bite, but and have no poison. Norwegian name: “Buorm”. English: “The grass snake” (Natrix natrix), sometimes called the ringed snake or water snake, – feeds almost exclusively on amphibians.
Makes a scary sound when you get close to take a photo, like I did….. You forget the no-poison thing and move back, like i did…..:-)
