a salamander that refused to grow up and accidentally became immortal-ish doing it

means A neotenic Mexican salamander that keeps its juvenile, gilled aquatic form for life and can regrow lost limbs, organs, and even parts of its brain.

from Straight from Nahuatl, the language of the Aztecs: 'axolotl' joins 'atl' (water) with 'xolotl' — which can mean servant, slave, or monster, and is also the name of Xolotl, the dog-headed god of lightning, death, and twins. The popular gloss is 'water-dog' or 'water-monster,' and one telling has Xolotl himself fleeing sacrifice by diving into the water and turning into the creature. The Spanish carried the word into Europe largely intact, which is why a tongue-twisting Aztec name still labels a pet-shop animal today.
