An Ice Age Original
The Pyrenean desman, Galemys pyrenaicus, is a semi-aquatic mammal of the mole family, Talpidae. It is one of only two surviving desman species in the world. This small insectivore measures around 11-16 cm long, with a tail of a similar length, and weighs between 50 and 60 grams. Its distinctive feature is a long, flexible, trunk-like snout used to find prey underwater. The animal has dense, waterproof fur, large webbed hind feet for swimming, and strong forelimbs with claws for climbing and digging. Its small eyes give it very limited vision; it navigates its world almost entirely through touch.
The desman's snout is a highly developed sensory tool. It is covered in sensitive whiskers and specialized tactile receptors called Eimer's organs, which allow it to detect the subtle movements of prey in the riverbed. This anatomical feature enables the desman to hunt effectively in the dark, fast-flowing mountain streams it lives in. It can also close its nostrils and ears to prevent water from entering while submerged. The desman is primarily nocturnal and solitary, a secretive animal that is rarely observed directly by humans. Researchers often rely on camera traps and environmental DNA to confirm its presence.
