Peromyscus zarhynchus

Chiapan Deermouse

Order: Rodentia
Family: Cricetidae

 

Conservation Status: Vulnerable.


This is one of the largest deermice, the largest found in the cloud forests of north-central Chiapas. Only P. guatemalensis is as big, and although both are found in Chiapas, Mexico, their ranges do not overlap. P. mexicanus is also big, and can occur in the same locations, but if in doubt, measure their hind feet: the hind feet of P. zarhynscus are never less than 2 mm (about 1/8 inch) longer, and if you think that's ridiculous, you're not the only one. It is fairly common in both mature forest and second growth and even lives in some brushy areas where the big trees have been logged. At elevations below 2,200 m, it is found only among tall trees. Its habits are not well known, but it is mainly terrestrial.
