How much does a Merriam’s pocket mouse weight?

It is hard to guess what a Merriam’s pocket mouse weights. But we have the answer:

An adult Merriam’s pocket mouse (Perognathus merriami) on average weights 6 grams (0.01 lbs).

The Merriam’s pocket mouse is from the family Heteromyidae (genus: Perognathus). They can live for up to 2.5 years. When reaching adult age, they grow up to 5.8 cm (0′ 3″). Usually, Merriam’s pocket mouses have 4 babies per litter.

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.

Merriam’s pocket mouse (Perognathus merriami) is a species of rodent in the family Heteromyidae. It is found in northeast Mexico and New Mexico, Oklahoma and Texas in the United States. Its habitat is shortgrass prairie, desert areas with scrub and arid shrubland. The species is named to honor Clinton Hart Merriam, a biologist who first described several other members of the genus Perognathus, and first elucidated the principle of a “life zone” as a means of characterizing ecological areas with similar plant and animal communities.
