Northeastern Alabama supports a high diversity of salamanders, approximately twenty-eight species represented by five families (Ambystomidae, Crytobranchidae, Plethodontidae, Proteidae
, and Salamandridae).
Two species of salamanders that occur in South Dakota are very distantly related and represent two families, Ambystomatidae and Proteidae
. Larvae of the tiger salamander are occasionally incorrectly referred to as mudpuppies but are considerably different in most of their biology as well as appearance.
