Animal Weight

How much does a Japen rat weight?

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

An adult Japen rat (Rattus jobiensis) on average weights 380 grams (0.84 lbs).

The Japen rat is from the family Muridae (genus: Rattus). When reaching adult age, they grow up to 21.6 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.

The Japen rat (Rattus jobiensis) is a species of rodent in the family Muridae found only in Yapen, Biak-Supiori, and Owi islands of West Papua, Indonesia.
