Are frogs Gymnophiona?
Living amphibians are represented by three clades: Gymnophiona (caecilians), Caudata (salamanders), and Anura (frogs) (Table 1.1).
What separates frogs from salamanders and caecilians?
They are classified into three orders: frogs and toads, salamanders and newts, and caecilians. Frogs and toads are adapted for jumping. Salamanders and newts may walk or swim. Caecilians live in the water or soil and are the only amphibians without legs.

Where are caecilians found?
Despite reaching gargantuan lengths, these animals are rarely seen by people. Most species spend a majority of their lives underground or plying the waters of shallow streams. Caecilians can be found in tropical and neotropical areas around the world, from Central and South America to Central Africa and Southeast Asia.
How are caecilians different from other amphibians?
Caecilians belong to the same group of animals that includes frogs and salamanders. But unlike other amphibians, caecilians lack legs. Some caecilians are as short as a pencil, while others grow as long as a child. Their eyes are tiny and hidden beneath skin and sometimes bone.
