Peromyscus simulus

Sinaloan Deermouse

Order: Rodentia
Family: Cricetidae

 

Conservation Status: Vulnerable.


"Simulus" comes from the Latin word for "similar," indicating that this tiny, tawny-colored deermouse does not differ much in appearance from other Peromyscus. It inhabits mangrove swamps, flood plains, acacia thickets, and other lowland coastal areas in western Mexico, and has not been found in dryer hillsides. Individuals caught in the northern part of its range are generally smaller than southerners. Only tidbits of information are available about reproduction in this deermouse: sexually active adults have been caught in February and September, and juveniles have been caught in May.

Length:
Range: Total Length: 91.3-207 mm; Tail: 90.4-105.8 mm
