Axolotls Stay “Forever Young”: Meet Neoteny
Why do adult axolotls keep their gills and baby face? The answer is one cool word: neoteny.
Axolotls are actually a kind of salamander, related to frogs and newts. Most salamanders hatch in water as gilled larvae, then transform (metamorphosis) and move onto land. My family does things differently.
Neoteny: staying larva-like for life
Axolotls grow up without metamorphosis. We keep our frilly external gills and the fin along our tail, and live in water our whole lives. Even so, axolotls can still reproduce like any other adult. This is called neoteny.
That’s why axolotl faces always look baby-cute. The smile isn’t an act; our faces are simply shaped that way! 😊
Can axolotls transform?
Yes, but very rarely. Under certain conditions, such as hormone exposure, an axolotl can metamorphose into a land salamander. The change is hard on its body and can shorten its life. So for axolotls, staying “forever young” really is the best option.
A few quick numbers
- In good care, axolotls can live 10–15 years.
- Adults are usually about 15–30 cm long.
- They mature (able to breed) at around one year old.
Pumi is “forever young” too, but mostly at heart: always curious like a little kid. 🎂
