It is hard to guess what a Peruvian tree-rat weights. But we have the answer:
An adult Peruvian tree-rat (Echimys rhipidurus) on average weights 315 grams (0.69 lbs).
The Peruvian tree-rat is from the family Echimyidae (genus: Echimys). When reaching adult age, they grow up to 21.3 cm (0′ 9″).
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 tree rat (Makalata rhipidura) is a species of rodent in the family Echimyidae. It is found in northeastern Peru and adjacent Ecuador, where it is found in the Amazon rainforest. It is nocturnal and arboreal.The etymology of the species name derives from the two ancient greek words ῥιπίς, ῥιπίδος (rhipís, rhipídos), meaning “fan”, and οὐρά (ourá), meaning “animal tail”.
