It is hard to guess what a Black-spined Atlantic tree-rat weights. But we have the answer:
An adult Black-spined Atlantic tree-rat (Echimys nigrispinus) on average weights 224 grams (0.49 lbs).
The Black-spined Atlantic 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.

It is found in southeastern Brazil, where it inhabits moist broadleaf forest and semideciduous forest in the Atlantic Forest region. It is arboreal and is believed to build nests of leaves in trees.
