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.
Instead, they consistute an evolutionary grade (a paraphyletic group), ancestral to living tetrapods such as lissamphibians (modern amphibians) and amniotes (reptiles, mammals, and kin). "Labyrinthodont"-grade vertebrates evolved from lobe-finned fishes in the Devonian , though a formal boundary between fish and amphibian is difficult to define ...
This is a list of amphibians found in the United States. A total of 306 amphibian species have been recorded in the United States , [ 1 ] 2 of which are now extinct. [ 2 ] This list is derived from the database listing of Amphibian Species of the World .
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 ).
This is a checklist of amphibians found in Northern America, based mainly on publications by the Society for the Study of Amphibians and Reptiles. [1] [2] [3] The information about range and status of almost all of these species can be found also for example in the IUCN Red List of Threatened Species site. [4]
The Lissamphibia (from Greek λισσός (lissós, "smooth") + ἀμφίβια (amphíbia), meaning "smooth amphibians") is a group of tetrapods that includes all modern amphibians. Lissamphibians consist of three living groups: the Salientia ( frogs and their extinct relatives), the Caudata ( salamanders and their extinct relatives), and the ...
