Source for information on patagium: A Dictionary of Zoology dictionary. The lizard has a dorsal-rib-supported patagium, a structure independently evolved in the Late Triassic basal lepidosauromorph kuehneosaurs and the extant agamid lizard Draco, revealing a surprising case of convergent evolution among lepidosauromorphans. The modifications of the trunk musculature have been published elsewhere (John 1970). This genus is distributed in southern India and throughout Southeast Asia (Fig. Downloaded at Microsoft Corporation on May 13, 2020 5508 www.pnas.orgcgidoi10.1073pnas.0609552104 Li et al.

Flying Lizards of the agamid genus Draco are the most specialized and best-studied gliding reptiles [ 2, 4 – 6 ]. Comparisons of patagial area are also made between selected species of Draco. The species occurs at various localities in forested areas of Sulawesi. Little is known of its diet and behaviour. Coloration of female D. volans was similar to that of conspecific males. The structure is found in living and extinct groups of animals including bats, birds, some dromaeosaurs, pterosaurs, gliding mammals, some flying lizards, and flying frogs. [4] Sometimes these flaps of skin are referred to as its "wings" [5] or pseudo-wings because the skin folds act more like parachutes than wings. Although toe-clipping has been used to study Draco lizards , , the treatment effects remain unknown but are suspected to reduce survival and alter behaviour.

The patagium (plural: patagia) is a membranous structure that assists an animal in gliding or flight. Draco dussumieri, the South Indian Flying Lizard is unique in having a patagium for gliding from tree to tree. The genus Draco Linnaeus, 1758, consisting of some 21 species, is one of the most prominent genera of the family Agamidae, characterized by the presence of patagium (a winglike skin-extension, supported by elongated ribs, along the flank). The snout-to-vent length is about 108 millimetres (4.25 in). In both taxa, ventral ground colors of males were bluish grey, whereas those of females were yellowish white or white. Patagium structures are also found in at least two other extant lizard lineages, both geckos, but patagium in Draco species are far larger and supported by active and highly modified musculature. "clr": true, Scale architecture of the patagium of Draco is described and is related to pertinent aspects of the structure and properties of the integument. The integrative patagial morphology of Draco volans was examined to elucidate the possible evolutionary pathway of origin of active patagia in the flying dragons and in extinct taxa that are thought to have possessed similarly constructed flight membranes. [1] One each side of a body, a thin fold of skin extends between the fore- and hindlimbs.

Spangengleiter Oder: Fliegende Reptilien Übersicht Einführung Gleitflug Spangengleiten Fliegende Echsen Draco spec. Associated with the development of the patagium, the musculature has undergone a number of adaptive modifications. The agamid lizard genus Draco is the most remarkable and successful of the gliding vertebrates and they are well-known as flying lizards due to their ability to glide long distances between trees using a wing-like patagial membrane (patagium), supported by 4–7 elongated ribs or rib-like dermal structures on each side of the body (McGuire, 1998, McGuire and Dudley, 2011, Smith, 1935).

In both taxa, ventral ground colors of males were bluish grey, whereas those of females were yellowish white or white. controlled structure supported by elongated thoracic. The Draco patagium is unique among living animals in that it is an actively controlled structure supported by elongated thoracic ribs and a specialized musculature (Colbert 1967; John 1970a; Russell and Dijkstra 2001). What is unique about the patagium of the Flying Lizard is rather than extending from the arms to the legs, it is supported by ribs. Examination of preserved Draco specimens suggest that the cambering and the tension of the patagium can be altered by arching or straightening of the back and, to a lesser extent, movements of the hindlimbs, as the posterior end of the patagium is attached to the proximal portions of the thighs. The dorsal surface is mottled brownish-grey with darker speckling. Ptychozoon spec.

Both sexes have a thick, black transverse band that extends across the posterior gular region from one throat lappet to the other.
