The Pyrenean desman is a small semi-aquatic mammal from the mole family. It has a long flexible snout, webbed feet, and a flattened tail, which help it live and hunt in cold mountain rivers.
The Pyrenean desman differs from other desmans and moles with special adaptations to life in fast cold streams. It is important for nature as an indicator of water purity, as it quickly disappears when rivers are polluted.
