There are more than 7,000 species of amphibians currently known. The vast majority of amphibians are frogs, toads, and caecilians. However, amphibians face the threat of habitat loss, climate change, and diseases. Populations worldwide are diminishing. Around 30% are threatened with extinction, which is more than birds and mammals.
However, the majority of amphibians have not been assessed by the IUCN Red List. At least 42% of all known amphibian species are declining, and several of the species are now extinct. Members of this animal class include frogs, newts, salamanders, toads, caecilians, and blindworms.
