Humans marvel at the beauty of glowing organisms, but usually, nature’s light displays serve a much more practical purpose.

When pushed to the limit by a predator, the vampire squid envelops its adversary in a smokescreen of glowing particles. After ejecting luminescent mucus from the tips of its eight tentacles, this master of disguise makes its escape, “flying” through water with its fins rather than jet-propelling like most other cephalopods. The sticky mucus, which glows for up to 10 minutes, may even coat the predator and make it more vulnerable to attack.
