Pteromys volans Pteromys momonga Commonly referred to as the Old World flying squirrels, the genus Pteromys is distributed across temperate Eurasia, the Korean Peninsula and Japan.

Although there are a host of flying squirrel genera in Asia (particularly southern Asia), Pteromys is the only one present in Europe.

These large-eyed animals are nocturnal and use a membrane stretching from their wrists to ankles in order to glide from tree to tree.

They can glide up to 443 feet (135 m) and have a long flat tail.

They feed on nuts, seeds, fruit, buds, bark, and insects.
