Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals).

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 ...
[3] Similarly, laurasiathere perissodactyls and afrothere paenungulates have several features in common, to the point of there being no obvious distinction among basal taxa of both groups. [4] Many aquatic mammals or marine mammals independently came to have adaptations to live in water, such as similar-looking tail flukes in dugongs and whales.
List of amphibian genera lists the vertebrate class of amphibians by genus, spanning two superorders. Superorder Batrachia. Order Anura. Frogs ...
Wood frogs experience very little of the winter because they are frozen solid for the coldest eight months of the year. This is a high-risk strategy! If ice crystals form inside their body, they ...
Frogs and amphibians use "anti-freeze" to prevent organ damage while hibernating. Polar bears, foxes, and owls use insulated fur and feathers to protect from the cold conditions. [ 2 ] These complex interactions between plants, animals and abiotic factors in the tundra are held together by the permafrost layer, located 450 metres (1,480 ft ...
