Salamanders occur mainly in the temperate regions of the Northern Hemisphere.
They do not occur in Australia or south of the Sahara in Africa and are rare in South America. History Salamanders are a very old group that diverged early from the other amphibian stocks. A major subclass of extinct amphibians can be found in the fossil record. Members of these two orders were elongate. Some had limbs, some had reduced limbs, and some had no limbs.
