It is hard to guess what a Pearson’s chaco mouse weights. But we have the answer:
An adult Pearson’s chaco mouse (Andalgalomys pearsoni) on average weights 25 grams (0.06 lbs).
The Pearson’s chaco mouse is from the family Muridae (genus: Andalgalomys). When reaching adult age, they grow up to 10.1 cm (0′ 4″).
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.
Pearson’s chaco mouse (Andalgalomys pearsoni) is a species of rodent in the family Cricetidae. It is found in the Gran Chaco ecoregion of southeastern Bolivia and western Paraguay at elevations up to 400 m. The species is named after American zoologist Oliver Payne Pearson. Its karyotype has 2n = 76 and 78 in the two subspecies. The latter is the highest diploid number of any species in the tribe Phyllotini.
