There are more than 220 living species of caecilian classified in 10 families. Gymnophionomorpha is a recently coined name for the corresponding total group which includes Gymnophiona as well as a few extinct stem-group caecilians (extinct amphibians whose closest living relatives are caecilians but are not descended from any caecilian).
Subclass Lissamphibia (all modern amphibians, including frogs, toads, salamanders, newts and caecilians) Salientia (frogs, toads and relatives): Early Triassic to present—7,360 current species in 53 families. [10] Modern (crown group) salientians are described via the name Anura.
Amphibians use their skin as a secondary respiratory interface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards , but unlike reptiles and other amniotes , require access to water bodies to breed.
Most scientists have concluded that all of the primary groups of modern amphibians—frogs, salamanders and caecilians—are closely related. Some writers have argued that the early Permian dissorophoid Gerobatrachus hottoni is a lissamphibian. [2]

It belongs to a lineage believed to have given rise to the three living branches of amphibians - frogs, salamanders and limbless caecilians. Creature named for Kermit the Frog offers clues on ...
One of them, a group of semiaquatic reptiles known as the Choristodera, became extinct 11 million years ago for unclear reasons. [70] The seven Cenozoic tetrapods groups are: Lissamphibia: frogs, salamanders, and caecilians; Mammalia: monotremes, marsupials, placentals,and †multituberculates
But the researchers determined the specimen is from the group temnospondyls, which are believed to be the most common ancestor of all lissamphibians — a category that includes frogs, salamanders ...
