The family Soricidae consists of 23 genera and about 314 species, of these 12 genera and 126 species occur in Eurasia.
Shrews are the smallest of the insectivores, one species Suncus etruscus of southern Europe and Asia is one of the smallest known mammals.
Soricdae are divided into two sub-families Cocidurinae white toothed shrews and the Soricinae red toothed shrews.
There is still a considerable need for research both at the taxonomic and ecological levels. For many species no details of their ecological requirements are available, many being known only from a single location and a few records.
