Yes, more salamanders from the genus Ambystoma are likely to be more closely related to each other than to Necturus (the mud puppy) or newts, as Ambystoma species share a more recent common ancestor. Ambystoma is a distinct group within the family Ambystomatidae, while Necturus belongs to a different family, Proteidae, and newts are classified under the family Salamandridae. This evolutionary divergence means that Ambystoma salamanders are more genetically similar to one another than to representatives from other salamander families.

Mudpuppies and waterdogs are large neotonous salamanders (salamanders that retain their gills in adulthood). Often used for bait in fishing they are generally green or brown in color. Mudpuppies are Necturus maculosus of the family Proteidae and remain neotonous. Waterdogs can mature into tiger salamanders.
The scientific or taxonomic name would be Bufo microscaphus.
