Quick Summary

Sorex is a genus of shrews, which are small mammals belonging to the family Soricidae. These shrews are widely distributed and characterized by their reddish-brown-tipped teeth. Shrews, in general, are insectivores with mobile snouts, sensitive whiskers, and sharp incisor teeth used for catching prey. They possess scent glands that produce a foul odor and have high metabolic rates, requiring them to eat frequently. Shrews inhabit diverse environments across North America, South America, Africa, and Eurasia. The genus Sorex specifically includes Holarctic shrews found in Europe, Asia, and North America.12
