The Wild Axolotl
Digest
This podcast episode focuses on the axolotl, a unique aquatic salamander native to Mexico and surprisingly popular due to its appearance in Minecraft. The episode highlights the paradox of a larger captive population than wild population, a consequence of their relatively easy breeding in captivity. The podcast features Horacio Mena, an axolotl veterinarian working in Xochimilco, who discusses the axolotl's cultural significance in Aztec mythology and its remarkable regenerative abilities. Horacio explains the three primary threats to the axolotl's survival: habitat loss due to urban growth, the introduction of invasive fish species, and water pollution. The episode concludes by outlining conservation efforts, including the removal of invasive fish, the creation of axolotl refuges on abandoned Chinampas, and the reintroduction of captive-bred axolotls into the wild. These efforts aim to restore the axolotl's natural habitat and prevent its extinction.

Show Notes
Why are there so many axolotls in fishtanks, and so few in the wild? That’s what Maximiliano wants to know. You may have found axolotls in the lush caves of Minecraft, but in real life, they live in the lakes and canals of Xochimilco, near Mexico City. But the species is slowly disappearing from its native habitat. Axolotl veterinarian Horacio Mena takes us on a journey to Xochimilco to find out what scientists are doing to save these adorable amphibians.
