Axolotl: The Peter Pan of Evolution
Axolotls never grow up, at least not like other salamanders do. They keep their baby features forever, including those wild external gills. Their eyes sit way out on the sides of their heads, perfect for spotting food or danger. Those frilly gills wrap around their heads like a fancy collar. People think they’re smiling, but that’s just how their mouth sits. The same stem cells that let them regrow lost body parts also keep them looking forever young. Pink ones aren’t found in nature. Scientists bred them in labs because their transparent skin makes it easier to study how they regenerate.
