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. The list of species is: * Tribe Anourosoricini ** Genus ''Anourosorex'' (Asian mole shrews) *** Assam mole shrew, ''A. assamensis'' *** Giant mole shrew, ''A. schmidi'' *** Chinese mole shrew, ''A. squamipes'' *** Taiwanese mole shrew, ''A. yamashinai'' * Tribe Blarinellini ** Genus ''Blarinella'' (Asiatic short-tailed shrews) *** Indochinese short-tailed shrew, ''B. griselda'' ** ...

Crawford's Gray Shrew
Crawford's gray shrew (''Notiosorex crawfordi''), also known as the desert shrew, is a small shrew found in the southwestern United States and northern Mexico. It is a member of the family Soricidae of the order Eulipotyphla. It was the only known member of the genus '' Notiosorex'' until two species, ''N. villai'' distributed in Tamaulipas, Mexico, and ''N. evotis'' distributed along the northwest coast of Mexico, were named. A fourth distinct species, ''N. cockrumi'', was discovered in Arizona and named in 2004. Description Crawford's gray shrew is one of the smallest desert mammals and one of the world's smallest homeotherms. When fully grown, it will only grow to a size of about long, half of which is the tail, and it will only grow to a weight of about . It is gray-brown with light gray under parts. The long tail is gray with it being lighter underneath. It has small, but relatively prominent, ears. A Crawford's gray shrew is born during the summer months to a litte ...

Southwestern United States
The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that generally includes Arizona, New Mexico, and adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Prior to 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While the region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitude) t ...
