Sorex
The genus ''Sorex'' includes many of the common shrews of Eurasia and North America, and contains at least 142 known species and subspecies. Members of this genus, known as long-tailed shrews, are the only members of the tribe Soricini of the subfamily Soricinae (red-toothed shrews). They have 32 teeth. These animals have long, pointed snouts, small ears, which are often not visible, and scent glands located on the sides of their bodies. As their eyesight is generally poor, they rely on hearing and smell to locate their prey, mainly insects. Some species also use echolocation. Distinguishing between species without examining the dental pattern is often difficult. In some species, a female shrew and her dependent young form "caravans", in which each shrew grasps the rear of the shrew in front, when changing location.

Red-toothed Shrews
The red-toothed shrews of the subfamily Soricinae are one of three living subfamilies of shrews, along with Crocidurinae (white-toothed shrews) and Myosoricinae (African white-toothed shrews). In addition, the family contains the extinct subfamilies Limnoecinae, Crocidosoricinae, Allosoricinae and Heterosoricinae. These species are typically found in North America, northern South America, Europe and northern Asia. The enamel of the tips of their teeth is reddish due to iron pigment. The iron deposits serve to harden the enamel and are concentrated in those parts of the teeth most subject to wear. Members of the genera '' Chimarrogale'', '' Nectogale'', '' Neomys'' (Nectogalini) and some members of '' Sorex'' (Soricini) are known as water shrews, due to having a semi-aquatic lifestyle. Species The list of species is: * Tribe Anourosoricini ** Genus '' Anourosorex'' (Asian mole shrews) *** Assam mole shrew, ''A. assamensis'' *** Giant mole shrew, ''A. schmidi'' *** Chin ...
