Mole salamanders, tailed amphibians that are related to frogs and toads, spend very little time in ponds, which are used only during a two- or three-week breeding period.

The mole salamanders (genus Ambystoma) are a group of salamanders endemic to North America, the only genus in the family Ambystomatidae.

Polyploid mole salamanders (mostly triploids) are all female and reproduce by kleptogenesis, "stealing" spermatophores from diploid males of related species to trigger egg development but not incorporating the males' DNA into the offspring.

However, cladistic analysis of the mole salamanders found the existence of Rhyacosiredon makes Ambystoma paraphyletic, since the species are more closely related to some Ambystoma species than those species are to others in Ambystoma.

The only family in this genus is the Ambystomatidae.

Rhyacosiredon used to be considered a separate genus within the family Ambystomatidae.

In 2006, a large study of amphibian systematics placed Dicamptodon back within Ambystomatidae, based on cladistic analysis.

The Ambystomatidae originated approximately 81 million years ago (late Cretaceous) from its sister taxon Dicamptodontidae.

The Ambystomatidae are also members of suborder Salamandroidea, which includes all the salamanders capable of internal fertilization.

Ambystomatidae was isolated to the southeast of the mid-Continental or Western Interior Seaway during the Cretaceous ( 145.5-65.5 Ma).

For example, species of salamanders in the family Proteidae are obligate paedomorphs, whereas species belonging to the Ambystomatidae are facultative paedomorphs.

The mole salamanders (genus Ambystoma) are a group of salamanders endemic to North America, the only genus in the family Ambystomatidae.

A fossorial organism is one that is adapted to digging and life underground such as the badger, the naked mole rat, and the mole salamanders Ambystomatidae.

Originally the genus Rhyacotriton was placed in the family Ambystomatidae, later in the family Dicamptodontidae, and finally in 1992 it was placed into a family of its own.

While three other species of the Ambystomatidae (A. tigrinum, A. californiense, and A. gracile) have overlapping ranges in western North America, the long-toed salamander's closest living sister species is A. laterale, a native to northeastern North America.
