Pygmy shrew Sorex minutus, photographed by Pavluvčík.

Belongs within: Soricinae.

Sorex, the long-tailed shrews, is a genus found in most of the temperate and Arctic regions of the Northern Hemisphere, predominately in moist habitats (Nowak 1999). The common shrew S. araneus is widespread in northern Europe and northwestern Asia. It is larger with a relatively shorter tail than the widely sympatric pygmy shrew S. minutus.

Characters (from Nowak 1999): Head and body length 46-100 mm, tail length 25-82 mm, adult weight 2.1-18.0 g. Tail a third to more than half of total length, hairy in the young, naked in old adults. Fur sleek; pelage uni-, bi- or tricoloured, colours varying from tan to black. Body slender; snout long, slender, highly movable, with conspicuous vibrissae. Eyes minute but visible; ears usually projecting slightly above pelage. Five upper unicuspid teeth present, with tips coloured brownish to purplish. Females with three or four pairs of mammae.
