Axolotls Can Regrow Legs, Tails, and Even Parts of Their Heart
My family’s superpower that keeps scientists curious: regrowing without a scar.
This is one of my favorite facts about my family. Axolotls are among the best regenerators in the animal world.
What can grow back?
When an axolotl loses part of its body, many parts can grow back with full shape and function, for example:
- legs and toes, complete with bones, muscles, and nerves
- the tail, including the spinal cord inside it
- parts of the heart and brain
What amazes scientists most: the regrown part usually leaves no scar.
How does it work?
After an injury, cells around the wound gather into a small cluster called a blastema. These cells act as if they’ve become “young again”, then rebuild the missing part following its blueprint. For a leg, this can take from several weeks to a few months.
Why does it matter for humans?
Researchers study axolotls to understand how bodies repair themselves. The hope is that one day this knowledge could help treat wounds, nerve injuries, or heart disease in people.
But don’t get me wrong: regeneration or not, axolotls can still get sick and stressed. A superpower is no excuse to treat us carelessly! 🩹
