The desert shrew, Notiosorex crawfordi, occurs in the southwestern and south-central United States, as well as in parts of Mexico. In Utah, the species occurs only in the extreme southern part of the state, where it prefers desert and arid grassland habitats.

Females may produce two litters of one to six young during the summer. Desert shrews are invertivores, primarily consuming insects and spiders. Interestingly, insects may sometimes be paralyzed and stored for later use. Desert shrews are active throughout the year, during both day and night. They are a common prey item for raptors, especially owls.
