It is hard to guess what a Peruvian fish-eating rat weights. But we have the answer:
An adult Peruvian fish-eating rat (Neusticomys peruviensis) on average weights 40 grams (0.09 lbs).
The Peruvian fish-eating rat is from the family Muridae (genus: Neusticomys). When reaching adult age, they grow up to 7.8 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.
The Peruvian fish-eating rat (Neusticomys peruviensis) is a species of semiaquatic rodent in the family Cricetidae. It is found only in eastern Peru, where it is known from locations at elevations from 200 to 400 m.
