An AXOLOTL is a type of larval salamander, which is a species of amphibian. It is also known as the Mexican walking fish due to its ability to walk on land. Axolotls are found in lakes and canals in Mexico City and have become an endangered species due to water pollution and urbanization. They are characterized by their distinctive external gills and long tails. Axolotls are popular in the pet trade and are used in scientific research due to their ability to regenerate lost body parts.
