Borneo is the world's third-largest island and its biodiversity is so amazing that Adam Tomasek, the environmentalist leader of WWF's team for Heart of Borneo region, estimates that "on average, there are three new species found every month."
A recent National Geographic piece has a stunning slide show of some of the most fascinating of these new species, including the Bornean flat-headed frog (seen above). While this is the one species pictured that is not actually a new discovery, what is new, and incredible, is the knowledge that this is the only frog in the world to breathe through its skin, rather than using lungs. This allows it to be flatter and survive better in its native surroundings.
