Axolotl

Axolotls, sometimes called Mexican walking fish, are the larval stage of salamanders, in the same way that tadpoles are the larval stage of frogs. Axolotls are a special case where they don't need to grow to the adult stage to breed. Axolotls come from a lake in Mexico, and they can live for about 15 years. They eat small water creatures that they suck into their mouths.
