How much does a Giant tree-rat weight?

It is hard to guess what a Giant tree-rat weights. But we have the answer:

An adult Giant tree-rat (Makalata grandis) on average weights 584 grams (1.29 lbs).

The Giant tree-rat is from the family Echimyidae (genus: Makalata). When reaching adult age, they grow up to 45 cm (1′ 6″).

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 giant tree-rat (Toromys grandis) is a species in the family Echimyidae, the spiny rats. It is the only species in the monotypic genus Toromys. It is endemic to Brazil, where it occurs in the flooded forest along the banks of the Amazon River and its tributaries.This species was formerly considered to be a member of the genera Loncheres and Makalata. In 2005 it was reclassified as the only member of the new genus Toromys.The etymology of the genus name derives from the onomatopoeic Portuguese word toró, referring to the vocalizations of this rodent, and the ancient greek word μῦς (mûs), meaning “mouse, rat”.
