Axolotls were also sold as food in Mexican markets and were a staple in the Aztec diet. [11] Axolotls may be confused with the larval stage of the closely related tiger salamander (A. tigrinum), which are widespread in much of North America and occasionally become paedomorphic, or with mudpuppies (Necturus spp.), fully aquatic salamanders from ...

The mole salamanders (genus Ambystoma) are a group of advanced salamanders endemic to North America. The group has become famous due to the presence of the axolotl (A. mexicanum), widely used in research due to its paedomorphosis, and the tiger salamander (A. tigrinum, A. mavortium) which is the official amphibian of many US states, and often sold as a pet.
The axolotl is also a relative of the tiger salamander. [35] [36] Axolotls live in a paedomorphic state, retaining most characteristics of their larval stage for their entire lifespans. While they never metamorphose under natural conditions, metamorphosis can be induced in them, resulting in a form very similar to the plateau tiger salamander.
Ambystoma dumerilii feeds by the use of gill rakers which they use to form a sucking motion to pull in food. [4] This is achieved via water being pushed through the buccal cavity and out the gills, trapping prey in the mouth. Juveniles and adults largely rely on smell to locate food and identify prey based upon movement.
