The science, gently

  • Axolotls can regrow entire limbs, and even repair parts of their heart and brain.
  • They keep their feathery gills their whole lives, staying water babies forever.
  • Their only wild home is one lake system in Mexico, which people are working to protect.

Wonder together

  • If you could regrow anything, what would you never worry about again?
  • Why do you think axolotls look like they are smiling?
  • What is one small thing you could do for animals that have only one home?

Tonight's calm-down

Axolotls heal by resting; stillness is their superpower. It is yours tonight too. Every quiet minute, your body patches and tidies and grows. Smile the axolotl's small smile, and let it work.

There's so much more to explore.

The episode is a whole story on its own. But if the wondering keeps going after the audio ends, the Family Guide opens this one all the way up: the same calm voice, turned into something you can do together at the table the next morning.
