Desert Shrew

Desert Shrews are tiny mammals, averaging just three inches in length, with their tail making up about a third of that. They have grayish brown fur on their backs and lighter gray fur on their undersides. Their narrow snout, tiny black eyes, and small rounded ears give them a delicate, distinctive look.

Habitat & Range

Desert Shrews are found across the southwestern United States from California to Texas. In Nevada, they live in a wide range of habitats, including deserts, shrublands, and grasslands in the southern part of the state. These tiny mammals are secretive and rarely seen, spending most of their time hidden under vegetation, rocks, or loose soil.

  • Grasslands
  • Mojave desert

Threats

  • Habitat Loss
  • Predation

Desert Shrews are mostly nocturnal, resting during the hottest parts of the day to save energy and stay cool. At night, they become quick and active hunters, darting through vegetation and soil in search of larval and adult invertebrates. Their narrow snouts and tiny sharp teeth are perfectly designed for catching and eating their prey.

Because they are so small and active at night, very little is known about their social behavior or reproduction. Their bodies are well adapted to arid environments, allowing them to survive on little or no free water. Most of the moisture they need comes from the food they eat.

Fun Facts

The Desert Shrew uses echolocation to navigate in the dark! Some species of shrews are actually venomous, the Desert Shrew is not, however.
