Pteromys volans orii Copulation | Japanese Flying Squirrel

This is a pair of Japanese dwarf flying squirrels (Pteromys volans orii) engaged in copulation. This is an extended process spanning many hours, during which the male often needs to fend off rivals while engaging in repeated bouts of copulation. As shown here, the female can, and often does, put up some measure of resistance, occasionally dislodging the male completely. The male’s penis is visible.
