It is hard to guess what a Mountain giant Sunda rat weights. But we have the answer:
An adult Mountain giant Sunda rat (Sundamys infraluteus) on average weights 419 grams (0.92 lbs).
The Mountain giant Sunda rat is from the family Muridae (genus: Sundamys). When reaching adult age, they grow up to 12.6 cm (0′ 5″).
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 mountain giant Sunda rat, Sundamys infraluteus (also known as the giant mountain rat or giant rat of Sumatra) is a large rat, around 480 to 640 millimeters (19 to 25 inches) in total length (230 to 290 millimeters [9-11.5 inches] excluding the tail). It weighs 230 to 600 grams. This makes it somewhat larger than a Norway rat, which averages around 300 grams, with 500 grams being unusually large. The rat is mostly dark brown with paler brownish specks. Its long fur is covered with even longer guard hairs. The tail is uniformly brown.
