Golden toad

The golden toad, which is sometimes referred to as the Monteverde toad or the orange toad, was a species that lived only in the Monteverde Cloud Forest Biological Reserve in Costa Rica. It was once a common species, but no specimen has been seen since 1989. The toad’s breeding sites were well-known and closely watched — in 1988, only eight males and two females could be found, and in 1989, only a single male could be located. Extensive searches for the golden toad since then have failed to locate another specimen, and the species was declared extinct in August 2007. The amphibian disease chytridiomycosis, airborne pollution and global warming probably contributed to the species' demise.
