The adder is the only venomous snake to cross the Arctic Circle. Its dark, melanistic color variant is particularly advantageous in northern latitudes for absorbing maximum solar radiation (albedo minimization) at low temperatures.

## FAQs

- **What is the adder (Vipera berus)?**: Vipera berus is a diurnal venomous snake, easily recognizable by the distinct zigzag pattern on its back. It is also viviparous, which ensures its survival in the boreal cold.
- **Which habitats in Västerbotten does it prefer?**: It favors sun-exposed edges of aapa mires, clearcuts in commercial forests, and dwarf-shrub heathlands in the subalpine zone. Rocky south-facing slopes are essential as winter dens.
