Axolotls are used extensively in scientific research due to their ability to regenerate limbs. In this way, salamanders can reproduce and survive in the form of a smaller larval stage, which is aquatic and requires a lower quality and quantity of food compared to the big adult, which is terrestrial.
Amphibian Species of the World: The axolotl is also considered an ideal animal model for the study of neural ajolite closure due to the similarities between human and axolotl neural plate and tube formation, which unlike the frog, is not hidden under a layer of superficial epithelium.
Axolotls exhibit neotenymeaning that they reach sexual maturity without undergoing metamorphosis. Retrieved 30 July There is some evidence that axolotls might seek out appropriately-sized gravel for use as gastroliths  based on experiments conducted at the University of Manitoba axolotl colony.
