Found in lakes near Mexico City, axolotls are salamanders affected by a phenomenon called neoteny, which means that adults of the species often fail to undergo metamorphosis and reach reproductive maturity without losing their larval characteristics. They are able to regenerate most body parts and are used extensively in scientific research. Axolotls are also commonly kept as pets in several countries and are considered a delicacy in Mexico.
