Peromyscus slevini

Catalina Deermouse

Order: Rodentia
Family: Cricetidae

 

Conservation Status: Critically Endangered.


The Catalina Deermouse may or may not still exist in its only known locality, Catalina Island off Baja California Sur. In 1931, these large deermice were abundant and even seen running around in the daytime. In the 1990s, only nineteen were trapped, and they were later re-identified as Peromyscus eremicus, a species that competes with P. slevini. P. eremicus was not known to live on Catalina Island, and may have come with fishermen.
