How much does a Hylaeamys megacephalus weight?

It is hard to guess what a Hylaeamys megacephalus weights. But we have the answer:

An adult Hylaeamys megacephalus (Oryzomys capito) on average weights 57 grams (0.13 lbs).

The Hylaeamys megacephalus is from the family Muridae (genus: Oryzomys). It is usually born with about 3 grams (0.01 lbs). They can live for up to 3.75 years. When reaching adult age, they grow up to 12.2 cm (0′ 5″). On average, Hylaeamys megacephaluss can have babies 6 times per year with a litter size of 3.

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.

Hylaeamys megacephalus, also known as Azara’s broad-headed oryzomys or the large-headed rice rat, is a species of rodent in the genus Hylaeamys of family Cricetidae, of which it is the type species. It is found mainly in lowland tropical rainforest from its type locality in Paraguay north through central Brazil, French Guiana, Guyana, Suriname, and Venezuela onto Trinidad and Tobago. To its west and east, other closely related species of Hylaeamys are found: H. perenensis in western Amazonia, H. acritus in Bolivia, and H. laticeps and H. oniscus in the Atlantic Forest of eastern Brazil.It was first described by Spanish naturalist Félix de Azara. Based on his description, several names were given to the animal, including Mus megacephalus Fischer, 1814 and Mus capito Olfers, 1818, both of which were largely forgotten for over a century. When capito was rediscovered in 1960, it came in use (as Oryzomys capito) for a “species” that included about all species now placed in Euryoryzomys, Hylaeamys and Transandinomys. Later, its scope was restricted, most definitively in a detailed study in 1998 by Guy Musser and coworkers, who also reinstated the older name Mus megacephalus (as Oryzomys megacephalus). In subsequent years, the western Amazonian H. perenensis was reinstated as a species and both were moved to the new genus Hylaeamys, because they are not closely related to the type species of Oryzomys.
