High Quality Content by WIKIPEDIA articles! The Panamanian golden frog (Atelopus zeteki) is a critically endangered toad which is endemic to Panama. It has been considered a subspecies of A. varius, but is now generally regarded as a separate species. 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.
