Wallace's Flying Frog, Borneo, 2000Photograph by Tim LamanSilhouetted against the night sky, a Wallace's flying frog (Rhacophorus nigropalmatus) glides through the air in Borneo. These frogs, the largest of Borneo's flying frogs, gather on branches above murky pools to breed and lay eggs. The pools then make ideal habitat for tadpoles, which drop into the water when they hatch.
