Wallace's flying frog (Rhacophorus nigropalmatus) Wallace's flying frog is a relatively small organism (15 - 20 mm) that possesses a distinct large eye. A tympanum membrane is located posterior to the eye. This anatomical feature serves as an eardrum to Rhacophorids as well as to other species of Anurans. The colour of the body is a shiny green with lighter yellow on the lateral sides as well as on the toe pads and snout. Wallace's flying frog is an arboreal amphibian that has a terminal segment of each finger and toe which is expanded into specialized toepads that allow these treefrogs to adhere to vertical surfaces. In addition to toepads flying frogs have huge, fully webbed hands and feet, also skin along the side of the body. These provide an increase in surface area so that when the limbs, fingers and toes are extended apart they allow the frogs to glide from high perches. The hindlimbs are relatively larger then the forelimbs and provide thrust upon jumping.
