The desman, a snouted and naked-tailed diving insectivore of the tribe Desmanini, belongs to one of two Eurasian species of the mole family, Talpidae.

This tribe consists of two monotypic genera of semiaquatic insectivores found in Europe: one in Russia and the other in the northwest of the Iberian peninsula and Pyrenees. Both species are considered to be vulnerable. They have webbed paws and their front paws are not well-adapted for digging.

The Russian desman (Desmana moschata) is a small semiaquatic mammal that inhabits the Volga, Don and Ural River basins in Russia, Ukraine and Kazakhstan. It constructs burrows into the banks of ponds and slow-moving streams, but prefers small, overgrown ponds with abundance of insects, crayfish and amphibians. The Russian desman often lives in small (usually not related) groups of two to five animals, and appears to have a complex (but largely unstudied) communication and social system.

The Pyrenean desman (Galemys pyrenaicus) is a small semiaquatic, globally threatened mammal related to moles and shrews, and, along with the Russian desman (Desmana moschata), is one of the two extant members of the tribe Desmanini. The species occurs in north and central parts of Spain and Portugal, French Pyrenees, and Andorra, but severe range contractions have been documented across its geographic distribution.ф
