Saussure's shrew (Sorex saussurei) 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.
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.
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. They have 32 teeth.
The Eurasian pygmy shrew, often known simply as the pygmy shrew, is a widespread shrew of the northern Palearctic.
The slender shrew is a species of shrew. An adult slender shrew has a weight of 1.5–5.3 g (0.053–0.187 oz) and a body length of 4.7–6.0 cm (1.9–2.4 in), with a tail of 4–5 cm (1.6–2.0 in); this makes it one of the smaller shrews found in its range. It is distributed across northeastern North Korea, Hokkaidō, and the Russian Far East including the Kuril Islands.
The taiga shrew, also known as the even-toothed shrew can achieve a body length of about 67 millimeters, with a tail of about 43 millimeters. This shrew is very similar to the long-clawed shrew. This species inhabits forested mountain valleys, and is found across northern Eurasia. It ranges from the Baltic Sea area through the Lake Baikal region of Siberia into the Russian Far East and along the Baekdudaegan mountains of the Korean Peninsula.
The Olympic shrew is a rare species of shrew that lives in only 13 spots in northwest Washington state and, a recent discovery, in Burns Bog, located in Delta, BC.
The Kamchatka shrew is a species of mammal in the family Soricidae. It is endemic to Russia.
The greater stripe-backed shrew or stripe-backed shrew is a species of mammal in the family Soricidae. It is endemic to China.
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 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 Kashmir pygmy shrew is a species of mammal in the family Soricidae. It is found in India and Pakistan.
Portenko's shrew is a species of mammal in the family Soricidae that is endemic to Russia.
The fog shrew is a species of mammal in the family Soricidae. It is endemic to northern California and Oregon in the United States.
The Inyo shrew is a species of shrew found in the western United States. Not much is known about its behavioral and reproductive habits. It is small, very similar in appearance to the related dwarf shrew, but smaller and paler. It can be found in many different habitats, from rocky, mountainous regions to wetlands and riparian areas. While barely studied, their population is believed to be stable and not under any threat.
The chestnut-bellied shrew is a species of mammal in the family Soricidae. It is endemic to Mexico.
The Alaska tiny shrew is a species of shrew. It is endemic to Alaska.
