How can flying squirels fly?

Flying squirrels don't actually fly; instead, they glide through the air using a special membrane called the patagium, which stretches from their wrists to their ankles. When they leap from a height, they spread their limbs and the patagium expands, allowing them to glide efficiently. This adaptation helps them navigate through trees and evade predators. Their lightweight bodies and flat tails also aid in steering and stabilizing their glides.
