Peromyscus polius

Chihuahuan Deermouse

Order: Rodentia
Family: Cricetidae


Conservation Status: Near Threatened.

Many deermice in the genus Peromyscus occur in both the United States and Mexico, but Chihuahuan Deermice are found only in the Mexican state of Chihuahua. Like all deermice, they are active year-round. Deermice are opportunistic nocturnal foragers, eating whatever is available. They, in turn, are eaten by weasels and other carnivorous mammals, owls, and snakes. In the wild, deermice probably have an average lifespan of about a year, although captives, safe from predators, have lived several years.

Range: Head and Body: 70-170 mm; Tail: 40-205 mm

Range: 15 to more than 110 g
