Content overview: “Axolotls Can Learn and Remember Even in Complete Darkness, Study Finds”. Axolotls, the smiling aquatic salamanders famous for regenerating limbs, have a hidden cognitive talent: they can learn to associate a visual cue with food even in total darkness, according to new research. Scientists trained axolotls to expect food after a light flash, then tested them in pitch-black conditions. Remarkably, the animals still responded correctly, showing they weren't simply relying on sight.
This suggests axolotls possess a flexible learning ability that may involve other senses or internal cues. The findings challenge assumptions about amphibian intelligence and highlight how much remains unknown about these critically endangered creatures. As labs worldwide study axolotl regeneration, this cognitive discovery adds another layer to their biological marvel—and underscores why protecting their last wild habitat in Mexico's Xochimilco canals matters for science and biodiversity.
