It is hard to guess what a Blackish grass mouse weights. But we have the answer:
An adult Blackish grass mouse (Thaptomys nigrita) on average weights 19 grams (0.04 lbs).
The Blackish grass mouse is from the family Cricetidae (genus: Thaptomys). When reaching adult age, they grow up to 12 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 blackish grass mouse (Thaptomys nigrita) also formerly called the ebony akodont, is a rodent species from South America. It is found in Argentina, Brazil, Paraguay and Uruguay. It is the only species in the genus Thaptomys.
