Draco volans, the common flying dragon, is a species of lizard endemic to Southeast Asia. Like other members of genus Draco, this species has the ability to glide using winglike lateral extensions of skin called patagia.
This lizard grows up to 22 centimeters in length, including the tail. The body is tan in color with dark flecks. The patagium of the male is tan to bright orange with dark banding. The female's patagium has irregular markings rather than banding.
The wings of Draco volans are supported by its ribs, which form the skeleton of its wings. However, its elongated ribs are superadded to aid forming its wings, and not to assisting respiration.
This species is considered a passive glider, or parachutist. However, previous studies have also shown that it can be considered a gliding animal. This means that it doesn't have to deal with the aerodynamic and metabolic imperatives required for active flight.
The female common flying dragon digs a hole in the soil to serve as a nest, and lays eggs in it.
