This flying squirrel is a marsupial. A new born crawls into the mothers marsupium and stays until the mother weans off her offspring. An adult flying squirrel is able to glide between trees with the help of patagium, a furry parachute-like membrane that stretches from wrist to ankle. It has a fluffy tail that stabilizes in flight. The tail acts as an air rudder, working as an air brake before landing on a tree.
