The order Caudata is the amphibian group comprising the living salamanders (including newts, mud-puppies, axolotls, sirens, congo eels and the olm) and their extinct relatives back to their divergence from the Salientia (frogs). The term Urodela is similar in use but applies only to the crown group, i.e. living salamanders and the fossil forms falling within the group from the point where the living forms started to diversify.
