Can sugar gliders fly

No. Apart from bats, no mammal is capable of free flight.

However, Gliders - small marsupials in the possum family - can glide between treetops. Varieties include the Sugar Glider, Feathertail Glider, Greater Glider, Squirrel Glider, Pygmy Glider and Yellow bellied Glider. As they launch, their forelimbs and hind limbs splay out, exposing gliding membranes which extend from the equivalent of their wrists to the knees, and allow them to glide between treetops and poles. Most species can glide up to 90 metres, while the squirrel glider has been recorded at 100m.
