The Pyrenean desman is a small semi-aquatic animal found in the Pyrenees mountains. Also known as Galemys pyrenaicus, it is the only species in its genus and is considered endangered. Synonyms for the Pyrenean desman include Pyrenean water shrew, Pyrenean otter shrew, and Catalan water-rat. These names all reference the animal's semi-aquatic lifestyle and its physical appearance - its long snout is similar to that of a shrew, while its webbed feet and otter-like tail allow it to swim effectively. While the Pyrenean desman is not as well-known as some other endangered species, its unique adaptations and habitat make it an important part of the Pyrenees ecosystem.
