It is hard to guess what a Brazilian arboreal mouse weights. But we have the answer:
An adult Brazilian arboreal mouse (Rhagomys rufescens) on average weights 21 grams (0.05 lbs).
The Brazilian arboreal mouse is from the family Muridae (genus: Rhagomys). When reaching adult age, they grow up to 10.8 cm (0′ 5″).
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 Brazilian arboreal mouse (Rhagomys rufescens) is a South American rodent species of the family Cricetidae. It is found in the Atlantic Forest of southeast Brazil, often close to bamboo thickets. It can be distinguished from Rhagomys longilingua, the only other species in its genus, by the absence of spines among the hair. Formerly believed to be extinct after no sightings were recorded for over 100 years, the species has since been found in four localities. However, it is nowhere common, and all of these are forest fragments, and ongoing deforestation threatens the species’ survival. For these reasons, the International Union for Conservation of Nature has assessed its conservation status as being “vulnerable”.
