It is hard to guess what a Blackish grass mouse weights. But we have the answer:
An adult Blackish grass mouse (Akodon nigrita) on average weights 19 grams (0.04 lbs).
The Blackish grass mouse is from the family Muridae (genus: Akodon). When reaching adult age, they grow up to 3.7 cm (0′ 2″).
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.
