Pyrenean Desman

The Pyrenean desman (Galemys pyrenaicus), also known as the Iberian desman or trumpet rat, is a species of small semiaquatic mammal in the family Talpidae. It is endemic to the mountain ranges of the Pyrenees and to mountainous areas of the northwestern Iberian Peninsula, primarily the Cantabrian Mountains and the Sistema Central. Its distribution includes four European countries: Andorra, Spain, France, and Portugal. The species is closely related to the Russian desman. The Pyrenean desman shows anatomical features that resemble those of several other mammals, including the brown rat (notably a robust tail adapted for swimming), the European mole (with strong, clawed forelimbs and a sensitive snout), and the common shrew (with an elongated snout used to capture small arthropods). The distinctive trunk-like snout gives rise to the alternative name "trumpet rat". The species has very limited vision and relies primarily on a highly developed sense of touch for orientation and foraging. Its mobile, prehensile snout bears vibrissae at the base and Eimer's organs at the tip, specialized tactile structures. The desman is an insectivorous semi-aquatic species that inhabits mountain lakes and fast-flowing streams with clear water. Its diet consists mainly of aquatic larvae that are sensitive to pollution, including…
