Salamanders are part of a different group of amphibians. The group they belong to is called Caudata. Not all animals in this group are called salamanders, there are also newts, sirens, olms, etc but they are sometimes just lumped into being called salamanders.

The Appalachian Mountains of the United States is the salamander capitol of the world. A third of all salamanders are found in the United States.
