It is hard to guess what a Siberian flying squirrel weights. But we have the answer:
An adult Siberian flying squirrel (Pteromys volans) on average weights 143 grams (0.32 lbs).
The Siberian flying squirrel is from the family Sciuridae (genus: Pteromys). They can live for up to 3.75 years. When reaching adult age, they grow up to 16 cm (0′ 7″). On average, Siberian flying squirrels can have babies 1 times per year with a litter size of 2.
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 Siberian flying squirrel (Pteromys volans) is an Old World flying squirrel with a range from the Baltic Sea in the west to the Pacific Coast in the east. It is the only species of flying squirrel found in Europe. It is considered vulnerable within the European Union where it is now found only in Estonia, Finland and Latvia out of the 27 countries in the Union.
