The Panamanian golden frog (Atelopus zeteki) is a critically endangered toad which is endemic to Panama. While the IUCN still lists it as critically endangered, it may have been extinct in the wild since 2007. Individuals have been collected for breeding in captivity in a bid to preserve the species.
The species was filmed for the very last time in the wild in 2007 by the BBC Natural History Unit for the series Life in Cold Blood by David Attenborough. The remaining few specimens were taken into captivity and the location of filming was kept secret to protect them from potential poachers.
Populations of amphibians, including the golden frog, suffered major declines possibly due to the fungal infection, chytridiomycosis, which is an invasive fungal pathogen that reached El Valle, the home of the Panamanian Golden Frog in 2006.
