The Mexican axolotl (Ambystoma mexicanum), also known as the axolotl or “ajolote,” is a unique amphibian endemic to Mexico. At first glance, it resembles a salamander, but its feathery external gills—often described as “crown-like horns”—make it unmistakable.
In recent years, the axolotl has gained global popularity due to its unusual appearance and even as a trendy pet. However, this rising demand has accelerated its decline in the wild. According to the International Union for Conservation of Nature (IUCN), the axolotl is currently classified as Critically Endangered, meaning it faces an extremely high risk of extinction in the near future.
This article explains the current situation of the axolotl, the main causes behind its decline, and what we can do to help preserve this fascinating species.
Habitat: Native to ancient lakes and canals in Mexico, especially Lake Xochimilco near Mexico City. It prefers deep, vegetation-rich waters that provide shelter and breeding grounds.
Wild Population: Since 2006, it has been officially recognized as a critically endangered species. Surveys at that time counted fewer than 100 individuals in the wild, and numbers have continued to decline.
Captive Populations: While thousands exist in laboratories and breeding facilities worldwide, most of these captive-born axolotls cannot be released into the wild. Having grown up in controlled environments with easy access to food, they lack the survival skills needed in natural habitats.
The decline of the axolotl is largely linked to human activity. The main threats include:
Overexploitation
Food: Traditionally consumed in some parts of Mexico.
Medical research: Used in laboratories due to its remarkable regenerative abilities.
Pet trade: Its exotic look makes it popular among pet enthusiasts.
Despite legal breeding programs, a black market still thrives, with wild-caught individuals sold illegally.
Pollution and Habitat Loss
Urban expansion, untreated sewage, and agricultural runoff have severely polluted the waters of Xochimilco.
Lower water levels and habitat fragmentation have drastically reduced suitable living conditions.
Invasive Species
The introduction of tilapia and carp has devastated axolotl populations.
These fish not only compete for food but also prey on axolotl eggs and juveniles.
Disease Spread
Invasive species also introduced new parasites and diseases.
Pollution further weakens the axolotl’s immune system, making them more vulnerable to infections.
Efforts to save the axolotl are already underway, but more action is needed. Current strategies include:
Habitat Restoration
Ecological restoration projects in Lake Xochimilco aim to improve water quality, replant native vegetation, and promote eco-friendly tourism.
Legal Protection
In Mexico, the axolotl is under special protection status and listed in CITES Appendix II, which restricts international trade.
Authorities are pushing for stricter legal safeguards to strengthen conservation efforts.
Community and Individual Actions
Support conservation organizations: Volunteer or donate to groups working to restore axolotl habitats.
Responsible tourism: Avoid polluting or disturbing ecosystems when visiting Xochimilco.
Report illegal activities: Help curb poaching and trafficking.
Adopt sustainable habits: Follow the 3Rs (Reduce, Reuse, Recycle) to minimize pollution.
Raise awareness: Educate others—especially children—about the importance of protecting axolotls and other endangered species.
The Mexican axolotl is more than just a curious-looking amphibian—it is a cultural symbol of Mexico and a scientific treasure due to its extraordinary ability to regenerate limbs, spinal cords, and even parts of the heart and brain.
If effective conservation actions are not taken, this extraordinary species could vanish from the wild within our lifetime. Protecting the axolotl is not only about saving one animal—it is about preserving biodiversity, cultural heritage, and scientific opportunities for the future.
