Quick answer
The axolotl is a salamander from Mexico that keeps its larval features for life, including feathery external gills, and lives permanently in water instead of moving onto land. It is famous for its extraordinary ability to regrow limbs, parts of organs, and even portions of its brain. Critically endangered in the wild, it survives mainly in captivity and labs. Axolotls can live 10 to 15 years.

Biology
Axolotl (Ambystoma mexicanum) is classified as Amphibian with conservation status Critically Endangered. Typical weight about 0.25 kg; lifespan around 10–15 years.
Ecology
Diet: Carnivore (worms, insects, small fish). Habitat: Freshwater lakes and canals of Mexico City. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Neoteny: the salamander that stays young
Most salamanders transform from water-living larvae into land-living adults, but the axolotl keeps its juvenile form for life, a phenomenon called neoteny. It retains its feathery external gills and stays fully aquatic, breeding while still in what looks like a larval body.
Regeneration
The axolotl is one of the most studied animals in regenerative biology. It can regrow lost limbs, tail, parts of the heart and other organs, and even sections of its brain and spinal cord, often with little or no scarring. Scientists study it to understand how regeneration works and whether similar processes might help in human medicine.
Habitat and range
In the wild, axolotls live only in the remnants of the lake and canal system around Mexico City, especially Lake Xochimilco. This habitat has been drained, polluted, and invaded by non-native fish, leaving very few wild axolotls.
Conservation
The axolotl is Critically Endangered in the wild, with wild numbers reduced to a tiny fraction of their former range. Paradoxically, it is abundant in captivity as a pet and a lab animal. Restoring the canals of Xochimilco and reducing pollution are central to saving the wild population.
Research notes
Figures for axolotls (Ambystoma mexicanum) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter axolotls in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Critically Endangered) when discussing conservation.
