OverviewAI-generated

Amphibia is a class of organisms within the phylum Chordata and the subclass Tetrapoda. The taxon was established by Linnaeus in 1758 and is governed by the International Code of Zoological Nomenclature. Common names for this group include amphibians, البَرْمائَّات, Земнаводныя, Земноводни, and Divelfenneg. They are primarily studied through the fields of batrachology and herpetology.

These animals inhabit freshwater environments and reproduce via oviparity. Their diet consists mainly of insects, Isopoda, worms, and Arachnida. Amphibians are utilized for biological pest control. The group has been the subject of extensive scientific inquiry, with 122,008 records in PubMed and 9,037 records in iDigBio, including 168 media items from institutions in the United States.

The taxon dates back to approximately 370 million years ago, with a temporal range start in the Mississippian period. It is recognized as an accepted class by WoRMS. The topic appears on focus lists for Wikipedia articles and is referenced by 11,158 other encyclopedia articles.

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, but 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 (caecilians). 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 (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this.
