Weird Fact: The Mexican Walking Fish is not only perpetually cute in its long-lasting larval form – it also has the ability to regenerate lost body parts.
Despite the name, this little dude is not a fish but a salamander, native to Mexico. It’s also known as the Axolotl (Ax-oh-lot-ul).
The Axolotl is a pretty weird amphibian because it retains its larval form into adulthood – and even becomes sexually mature in this state.
This adaptation – neoteny – is often viewed as a backward step in evolution because it means the Axolotl can’t live on land or colonize new habitats.
But Walking Fish are hardy creatures, living 10-15 years, and you can even keep them as pets. Just bear in mind that you shouldn’t handle them much, and they can sometimes be cannibalistic so keeping multiple fellas in the same tank isn’t recommended.
