The Pyrenean desman (Galemys pyrenaicus) is a small semiaquatic nocturnal mammal related to moles and shrews, and is one of only two surviving species of the tribe Desmanini. The range of the species centers on northwestern Spain and northern Portugal, but it is under threat due to changes to its habitat. In Portugal it is called "toupeira-d'água", which means "water mole".
Along with the Russian desman (Desmana moschata), it belongs to the tribe Desmanini. There were previously a greater number of related species some millions of years ago in that tribe, but the other species have all since become extinct.
The Pyrenean desman is 11 to 16 cm (4.3 to 6.3 in) long with a rounded scale-covered tail of 12 to 16 cm (4.7 to 6.3 in). It weighs 35 to 80 g (1.2 to 2.8 oz). Pyrenean desmans have long sensitive noses, and small front paws but large webbed back paws. They can close off their nostrils and ears with valves in order to stop water penetration, and use echolocation.
The desman's body is covered in fur, with the exception of its tail and nose. Markings typical of the species are a brown body with a light coloured underside. The nose is black and is covered in whiskers, which it uses to feel the movement of prey as it sticks its nose into mud or crevices while searching for food. The Pyrenean desman can live at least 3.5 years. The animals are nocturnal hunters of small invertebrates, snails and shrimp. They breed up to three times a year, with the period of gestation lasting around thirty days. Three to four young are born in each litter.
Pyrenean desmans are proficient swimmers, suited to their aquatic habitat, although their claws also allow them to be good at climbing. They live in pairs, with the male having a slightly larger territory than the female. Both members of the pair scent mark. They have the reputation of being aggressive to other adult members of the species.
