Do you know the flying squirrels?

Flying squirrels-do they really fly or jump long distances with the aid of wing like organs? Is it a misnomer?

Do you know that there are 43 species of flying squirrel that actually cannot fly but only glide while moving between trees?

Once airborne, the squirrels have a high degree of maneuverability and are able to steer by adjusting the tautness of the patagia and using their tails as stabilizers.

How do they "brake"?
I have seem them in action but I never wondered how do they halt? In other words, how do they brake?
"The tail acts as a stabilizer in flight, much like the tail of a kite and as an adjunct airfoil when braking prior to landing on a tree trunk. "
