Golden Arrow Poison Frog

The wild population of these frogs has declined more than 80 percent in the last decade. The plummeting numbers of the frogs, which are endemic to Panama, is largely a result of chytridiomycosis, an infectious fungal disease that seems to be causing mass amphibian die-offs. The disease is still spreading, and deforestation is adding to the pressures faced by the frogs. Though there are captive-breeding programs in place for these amphibians, they will not be released into the wild until conditions improve.
