It is hard to guess what a Brazilian spiny tree-rat weights. But we have the answer:
An adult Brazilian spiny tree-rat (Makalata armata) on average weights 400 grams (0.88 lbs).
The Brazilian spiny tree-rat is from the family Echimyidae (genus: Makalata). They can live for up to 3.08 years. When reaching adult age, they grow up to 59.5 cm (2′ 0″). Usually, Brazilian spiny tree-rats have 1 babies per litter.
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 spiny tree rat (Makalata didelphoides) is a species of rodent in the family Echimyidae. It is found in Bolivia, Brazil, French Guiana, Guyana, Suriname, Venezuela, and Trinidad & Tobago where it lives in lowland tropical rainforest. There is also a population in Ecuador which is referable either to this species or to Makalata macrurus. It is nocturnal, and eats seeds.
