Draco dussumieri, also known commonly as the Indian flying lizard, the southern flying lizard, and the Western Ghats flying lizard, is a species of lizard in the family Agamidae. The species is capable of gliding from tree to tree. It is found principally in the Western Ghats and some other hill forests of Southern India. It is almost completely arboreal, found on trees in forests and adjoining palm plantations where it climbs trees to forage for insects and glides to adjoining trees by expanding the patagium, loose skin on the sides of the body which is supported by elongated ribs to act as wings. The skin on the sides of the neck is also extended to the sides using the hyoid bones of the tongue as support. During the breeding season males maintain small territories which they defend from other males while courting females. The male has a more colourful patagium than the female, and it prominently extends its yellow dewlap forward in display. Although living almost its entire life in trees, the female descends to the ground to lay eggs in soil. This is the species with the westernmost distribution within the genus Draco, the majority of species occurring in Southeast Asia. Description The southern flying lizard is brown with patches of grey that match the pattern of tree bark. It can change its colour to a limited extent. As an adult, it is has a total length of about , with a snout-to-vent length (SVL) of about and a tail length of . The head is round with a short snout, and the nostrils point upwards. It is active during the day after it has warmed up in the early morning sun. Males have a long yellow dewlap which is shorter in the females. This lizard climbs trees in search of insect prey on the trunks and leaps off when it reaches the top to land on adjoining trees. It is able to glide by extending its patagia, flaps of skin on both sides of the body that are supported by six elongated ribs with special musculature to extend them outwards. The muscles on the breast are also modified to breathe more efficiently and support its active lifestyle. In addition the sides of the neck are also stretched out to form a pair of smaller "wings" around the head. It is able to control the direction of the
