Ambystomatidae (Mole Salamanders)

The mole salamanders (genus Ambystoma) are a group of advanced salamanders endemic to North America, the only genus in the family Ambystomatidae. The group has become famous due to the presence of the axolotl (A. mexicanum), widely used in research, and the tiger salamander (A. tigrinum, A. mavortium) which is the official amphibian of many states, and often sold as a pet.
