Atolla jellyfish (Atolla Wyvillei)

This species of jellyfish is bioluminescent, which means that they can glow, make themselves light up. Instead of using their light to attract prey, they use it to attract other predators to attack it's attacker! Confusing, right?

A Marine Biologist named Edith Widder created a device that was based on the Atolla Wyvillei  and it was used to lure rarely seen predators from the deep for footage! Isn't that cool?
