Ptychozoon

Ptychozoon was a genus of arboreal geckos, endemic to Southeast Asia, known commonly as flying geckos, gliding geckos, or parachute geckos. They all are now placed in the genus Gekko in the family Gekkonidae. The biogeographic history of the genus Ptychozoon was deeply nested within that of the genus Gekko, the center of diversity of which is within Southeast Asia. Since dispersing into Southeast Asian rainforests, Pytochozoon, like other forest-dwelling vertebrates, adapted to facilitate gliding. All species in the genus Ptychozoon are characterized by cryptic coloration and elaborate webs surrounding the neck, limbs, trunk, and tail. These membranes help to conceal the gecko against trees. When the gecko leaps into the air, the flaps are used to generate lift and allow the gecko to control its fall. It can glide up to . Also it does a swoop at the end of its glide to land softly. A similar adaptation is found in geckos of the genus Cosymbotus. There were thirteen described species in the genus Ptychozoon.
