Meet the axolotl, that perpetually smiling Mexican salamander who's become an internet darling for good reason. This special installation at Acuario de Sevilla puts these critically endangered creatures center stage alongside sharks, turtles, and rays in thoughtfully designed habitats. It's a genuinely educational afternoon that'll leave kids wide-eyed and adults quietly googling "can I have a pet axolotl" (spoiler: you cannot).
