What snakes live in Estonia?

In Estonia, the most notable snake species are the common European adder (Vipera berus) and the grass snake (Natrix natrix). The European adder is the only venomous snake found in the country, recognizable by its distinctive zigzag pattern along its back. Grass snakes, on the other hand, are non-venomous and often found near water bodies. Both species play important roles in the local ecosystem.
