Peromyscus madrensis

Tres Marías Deermouse

Order: Rodentia
Family: Cricetidae


Conservation Status: Endangered.

Another deermouse known only from one island, the Tres Marías Deermouse may, in fact, be extinct. House rats (Rattus rattus) are now abundant on the island and may well have done in the smaller rodents.

Also known as:
Maria Madre Island Mouse

Range: Head and Body: 93.4-107 mm; Tail: 90.4-105.8 mm
