The family Talpidae includes the moles, shrew moles, desmans, and other intermediate forms of small insectivorous mammals of the order Eulipotyphla. Talpids are all digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers; whilst the quite unique star-nosed mole is equally adept in the water and underground. Talpids are found across the Northern Hemisphere and southern Asia, Europe, and North America, although none are found in Ireland nor in the Americas south of northern Mexico.

The first talpids evolved from shrew-like animals which adapted to digging late in the Eocene in Europe. The most primitive living talpids are believed to be the shrew-like moles, with other species having adapted further into the subterranean, and, in some cases, aquatic lifestyles.

Talpids are small, dark-furred animals with cylindrical bodies and hairless, tubular snouts. They range in size from the tiny shrew moles of North America, as small as 10 cm in length and weighing under 12 grams, to the Russian desman, with a body length of 18–22 cm, and a weight of about 550 grams. The fur varies between species, but is always dense and short; desmans have waterproof undercoats and oily guard hairs, while the subterranean moles have short, velvety fur lacking any guard hairs. The forelimbs of moles are highly adapted for digging, with powerful claws, and the paws turned permanently outwards to aid in shovelling dirt away from the front of the body. By contrast, desmans have webbed paws with a fringe of stiff fur to aid in swimming. Moles generally have short tails, but those of desmans are elongated and flattened.
