Ptychozoon kuhli, commonly known as Kuhl’s flying gecko or the common flying gecko, is a species of Asian gecko.
P. kuhli has adaptations to its skin, including flaps on either side of its body, webbed feet, and a flattened tail to allow it to glide over short distances. These geckos have a remarkable camouflage. The flaps of skin along their sides help them blend with tree bark. Often, the eyes are the only way to see them.
Flying geckos, like many other gecko species, have evolved intricate toe pads with microscopic hairs that can adhere to nearly any surface, including glass. source
