The Sugar Glider (Petaurus breviceps), sometimes called the Flying Sugar, is a small gliding possum native to eastern and northern mainland Australia, New Guinea, and the Bismarck Archipelago, and introduced to Tasmania. Although its aerial adaptation looks rather clumsy in comparison to the highly specialised limbs of birds and bats, the Sugar Glider can glide for a surprisingly long distance - flights have been measured at over 50 metres (55 yd) - and steer effectively by curving one or other of the patagium. It uses its hind legs to thrust powerfully away from a tree, and when about 3 metres (3 yd) from the destination tree trunk, brings its hind legs up close to the body and swoops upwards to make contact with all four limbs together. The Sugar Glider is a popular pet because of its sweet, lively, inquisitive nature. In the USA, keeping them as a pet is illegal in certain jurisdictions.
