Peromyscus bullatus

Perote Deermouse

Order: Rodentia
Family: Cricetidae


Conservation Status: Critically Endangered.

The Perote Deermouse has very big ears, which may help it detect predators. It lives in open, sandy habitat sheltered only by grasses and a few trees, in a low-lying area in east-central Mexico known as the Oriental Basin. The spread of agriculture into its habitat threatens its existence. Southern Rock Deermice (Peromyscus difficilis), which are slightly larger, live there, too, but Perote Deermice are never found in rocky areas. Scientists may conclude that the Perote Deermouse is a subspecies of Peromyscus truei. There are no known fossils.
