Flying squirrels can't really fly, they only use fur fins between their limbs to glide from tree to tree, but it often seems that they can. The patagio is the fold of skin that goes from the wrist to the ankle is what allows them to glide. Thus, the squirrels slide in a downward curve until they reach another tree.
Why do they seem to fly? Their acrobatic jumps often span 45 meters, and some species cover almost 90 meters in a single slide, something that may lead us to believe that they are actually flying. They are very agile animals and remember that the average squirrel barely weighs about 330-450 grams. Their body type and weight are determined by the type of habitat in which they survive.
