It is hard to guess what a White-eared pocket mouse weights. But we have the answer:
An adult White-eared pocket mouse (Perognathus alticolus) on average weights 23 grams (0.05 lbs).
The White-eared pocket mouse is from the family Heteromyidae (genus: Perognathus). When reaching adult age, they grow up to 7.5 cm (0′ 3″).
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The white-eared pocket mouse (Perognathus alticolus) is a species of rodent in the family Heteromyidae. It is endemic to the San Bernardino Mountains and the Tehachapi Mountains of southern California in the United States. There are two subspecies of P. alticolus in California, P. a. alticolus and P. a. inexpectatus, both of which are considered species of special concern by the California Department of Fish and Wildlife.
