Like the cave source, the bubble fish and them, axolotl fish live in pure darkness. They can only see signs of life produced by themselves and other creatures through a special luminary on their bodies.

These luminaries can be used to lure prey and scare off predators. Although they look terrifying, they pose no threat to us humans because they are only a few millimeters long.
