Eight highly ED amphibians have already disappeared forever, and many more have not been seen for decades and may also be lost. A total of 34 amphibians have been confirmed extinct by the IUCN Red List of Threatened Species, and a further 131 species may also have been wiped out and await verification. Many of these are also highly evolutionarily distinct.
Here we highlight some former EDGE amphibians that have disappeared in the last 500 years.
