Squamata, Sauria: Agamidae, Genus Draco, Gliding Lizards
The gliding lizards of the genus Draco inhabit southeast Asia, although one species occurs in India. They have evolved elongated ribs that support a membrane of skin that forms a wing-like structure, it is called a pterygium or patigium. True wings in birds, bats and pterodactys evolved from limbs, not ribs. There are about 40 species in the genus. They are agile in trees, but clumsy on the ground. Food includes ants and termites. Males tend to be territorial and brightly colored. Their ecological counterparts in the Western Hemisphere are often considered to be the anoles.
Spotted Flying Lizard, Draco maculata

The Spotted Gliding Lizard, Draco maculata (Gray, 1845). Photographed at Thale Noi, southern Thailand. This location is at the northern end of Lake Songhkla. D. maculata is a small species, with adults reaching a body length of about 82 mm and a tail that is 125 mm long. It feeds primarily on ants as they move past the waiting lizard sitting on a tree trunk. Draco maculata is widespread in Southeast Asia and may actually be several different species. It has five ribs supporting the patagium. It ranges from sea level to at least 1400 m above sea level. Like most Draco, the species are territorial, and the territory is defended by the male by displaying its dewlap, a flap of skin under its chin.

Draco sp., southern Thailand

Gliding lizards are often found on tree trunks. They sit with their head in the down position and wait for a column of ants to march by. Then, they simply lap them up as the ants come to them. This Draco was in southern Thailand and was not identified to species, but most likely it is D. maculata.

A gliding lizard (Draco sp.). Cleared and stained museum specimen showing elongated ribs that extend the flaps of skin (the patagium) along the body for increasing the lizards surface area for gliding. Note that this species has five pairs of elongated ribs.

Giant Flying Lizard, Draco maximus

The Giant Gliding Lizard, Draco maximus Boulenger, 1893. Photographed in the Danum Valley, Sabah, Malaysia (Island of Borneo). The animal in the photographed was found sitting on a tree trunk at night. Its body length reaches 139 mm making it the largest species in Borneo, and one of the largest in the genus. It lays clutches of 3-4 eggs on the floor of primary rainforests.

Draco sp. Central Cambodia

Draco sp. Central Cambodia. This lizard was found on a tree trunk during the day along a forest trail. This may be Draco indochinensis Smith 1935.
