All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona . Evolved to be mostly semiaquatic , amphibians have adapted to inhabit a wide variety of habitats , with most species living in freshwater , wetland or terrestrial ecosystems ...
All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.
As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.
