The red-toothed shrews of the subfamily Soricinae are one of three living subfamilies of shrews, along with Crocidurinae and Myosoricinae. 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.
The greater stripe-backed shrew or stripe-backed shrew is a species of mammal in the family Soricidae. It is endemic to China.
The Zacatecas shrew is a species of mammal in the family Soricidae. It is endemic to Mexico. It inhabits the southeastern Sierra Madre Occidental in the states of Durango, Zacatecas, and Jalisco, from 1,830 to 3,660 m elevation.
The Azumi shrew is a species of mammal in the family Soricidae. It is endemic to Japan, where it is found in the mountainous regions of central Honshu Island. It is a close relative of the Eurasian least shrew. It is threatened by habitat loss.
The Paramushir shrew is a species of mammal in the family Soricidae. It is endemic to Russia. Its natural habitat is temperate forests. It is likely named for Paramushir Island, home to several other species of shrew in the genus Sorex.
The Mount Lyell shrew is a species of mammal in the family Soricidae. It is named for Mount Lyell in Yosemite National Park, the area where the shrew has been most commonly found.
The large-toothed shrew or Mexican large-toothed shrew is one of 77 species within the genus Sorex. Registered on the IUCN Red List as vulnerable with a decreasing population, the Mexican large-toothed shrew has been recorded only 14 times in seven locations. The shrew is a member of the red-toothed shrew subfamily Soricinae, and the more taxonomically defined tribe Soricini. Members of the latter category exhibit long tails relative to body size.
The Carmen Mountain shrew is a species of mammal in the family Soricidae. It is endemic to Mexico.
The dwarf shrew is a species of mammal in the family Soricidae endemic to Arizona, Colorado, Montana, Nebraska, New Mexico, South Dakota, Utah, and Wyoming in the United States. The type locality is Estes Park, Colorado, USA.
The Mexican long-tailed shrew is a species of mammal in the family Soricidae. It is endemic to Mexico.
The ornate shrew is a species of mammal in the family Soricidae (shrews). It is endemic to western North America, ranging from Northern California in the United States to the Baja California peninsula in Mexico. Eight subspecies are known, including the extinct tule shrew, known only from four specimens collected in 1905, and the Suisun ornate shrew, a species of conservation concern in California. Through skull morphology research and genetic testing on Ornate shrew populations, it has been shown that there are three main genetic subdivisions: The Southern, Central and Northern. These three genetic subdivisions of Ornate shrew arose from populations of Ornate shrews getting geographically isolated from other populations.
Portenko's shrew is a species of mammal in the family Soricidae that is endemic to Russia.
The Apennine shrew is a species of shrew in the family Soricidae. It is endemic to Italy.
Saussure's shrew is a species of mammal in the family Soricidae, that is found in Mexico. There is also a disjointed population of shrews in Guatemala that is provisionally assigned to this species, but may represent a distinct species.
Sclater's shrew is a species of mammal in the family Soricidae. It is endemic to Mexico.
The San Cristobal shrew is a species of mammal in the family Soricidae. It is endemic to Mexico.

It is found at 2,743 m (8,999 ft) elevation in montane cloud forests.
The chestnut-bellied shrew is a species of mammal in the family Soricidae. It is endemic to Mexico.
