The Pyrenean Desman (Galemys pyrenaicus) has a waterproof fur and a long flat tail which can act as a rudder or propeller in the water. Pyrenean desmans live in the Pyrenees Mountains of France, northern and Central Spain and northern Portugal. It lives along the fast-flowing mountain streams. The Pyrenean Desman forages mainly at night on crustaceans and insect larvae. It is threatened by construction of hydro-electric plants and water pollution. It is thought that Pyrenean desmans slap the surface of the water to produce noises helpful in echolocation, although this is mere speculation.
The Pyrenean desman is listed as Vulnerable (VU), considered to be facing a high risk of extinction in the wild, on the IUCN Red List of Threatened Species
