Angel Island mouse
The Angel Island mouse or La Guarda deermouse (''Peromyscus guardia'') is a species of rodents in the family Cricetidae. It is endemic to Mexico, where it is historically known only from the island of Ángel de la Guarda, and nearby islets. The species is believed to be extirpated from the three smaller islands, and may be extinct on Ángel de la Guarda, as well. The species is threatened by predation by feral cats, and by competition from introduced rodents.
==Description==
The Angel Island mouse has pale grey-brown fur with white underparts and feet, and large, hairless ears. It is most readily distinguished from closely related species on the mainland by subtle characteristics of the skull, or through genetic or biochemical analysis. Adults range from in total length, including tails long. Females have four abdominal teats.
