The Panamanian golden frog is one of more than 100 species of disappearing harlequin frogs.

Scientists estimate that about 67 percent of harlequin frogs have disappeared due to fungus outbreaks driven by global warming.

Recent studies show the Earth's warming climate is contributing to the increase of chytrid disease, a fungus infection that is responsible for the extinction of many tropical frog species. The fungus, Batrachochytrium dendrobatidis, infects tadpoles and eventually attacks the skin of adults and kills them. Scientsts know the spore stage can swim through water to infect other frogs, but there is still much to know about how the disease spreads, and if it can survive in other animals.
