They think the frogs might all be dead already because no scientist has seen one since 1980. Scientists are not sure how the frogs died, but they do know that the fungus ''[[Batrachochytrium dendrobatidis]]'', which can kill frogs and other amphibians, came to the place where the frog lived. Other frogs that live in streams have also caught the disease [[chytridiomycosis]]. Human beings have also cut down the forests where the frogs live to make [[agriculture|farms]]
