The mole salamanders (genus Ambystoma) are a group of advanced salamanders endemic to North America. The group has become famous due to the study of the axolotl (A. mexicanum) in research on paedomorphosis, and the tiger salamander (A. tigrinum, A. mavortium) which is often sold as a pet, and is the official amphibian of four US states.

Ambystomatidae is a family of salamanders belonging to the Suborder Salamandroidea in the class Amphibia. It contains two genera, Ambystoma (the mole salamanders) and Dicamptodon (the Pacific giant salamanders).

Am­bystoma species typ­i­cally have rounded, blunt snouts with a broad head and rel­a­tively small eyes. They have promi­nent coastal grooves with a lat­er­ally flat­tened tail, which they use for swim­ming. Com­pared to fe­males, males have a longer tail and a bul­bous vent.

Am­bystom­atids are stout-bod­ied sala­man­ders of mod­er­ate size (10-30 cm adult length). Their tails are thick, their limbs ro­bust, their skin smooth and shiny, and many have bright color pat­terns. They ex­hibit the most de­rived pat­tern of spinal nerves known in sala­man­ders, and their diploid num­ber is 28.

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 ...

They are called mole salamanders because they are nocturnal and spend the day in leaf litter or in burrows on the forest floor. They are 4-12 inches in length and have long, flattened tails; small eyes; stout bodies; smooth skin; and short, rounded heads. Some species, like the tiger salamander, have bright spots.

Key Characters: Two rows of yellow or orange-yellow spots down back from behind eye nearly to tail tip; belly slate gray or black, sometimes with small white flecks. Similar Species: Tiger Salamander has a yellowish-black mottled venter, the toes …
