description Golden Toad Overview
The Golden Toad ( *Bufo periglenes*) was a small toad species native to a restricted cloud forest region of Costa Rica. Its notable characteristic was its bright golden coloration, a rare trait among Central American toads. Sadly, the species became extinct around 2004 after disappearing from observation in 1989. Scientists and conservationists study it as a stark example of amphibian vulnerability due to climate change and habitat loss.

help Golden Toad FAQ
Where was the Golden Toad originally discovered and what was its habitat?
The Golden Toad was discovered in 1966 in the Monteverde Cloud Forest Reserve of Costa Rica. It inhabited a very restricted range of high-altitude elfin cloud forest, typically above 1,500 meters. The toad was completely dependent on the unique microclimate of moisture and mist provided by the cloud forest.
What did the Golden Toad look like?
The Golden Toad was famous for its striking, brilliant orange or golden coloration, particularly in the males, which was highly unusual among amphibians. Males were smooth and brightly colored, while females were larger, darker, and had dark red splotches with yellow edges. They were small amphibians, measuring only about 5 centimeters in length.
When and why did the Golden Toad go extinct?
The Golden Toad was last seen in 1989, and it was officially declared extinct by the IUCN in 2004. Its disappearance is strongly linked to extreme drought conditions caused by the 1986–1987 El Niño event, which dried up the pools where they bred. This climate anomaly, combined with the spread of the chytrid fungus, is believed to have wiped out the population.
What is the scientific significance of the Golden Toad's extinction?
The Golden Toad's sudden disappearance became an iconic "poster species" for the global amphibian decline crisis in the late 20th century. It demonstrated how sensitive species restricted to narrow montane habitats are to slight changes in climate and moisture. Its extinction is frequently cited in climate change studies as evidence of the ecological impacts of global warming.
