The Atolla jellyfish, also known as the coronate medusa and alarm jellyfish, is found in deep-sea environments worldwide at between 1,000 and 4,000 meters / 3,200 — 13,000 feet below the surface.
In common with many deepwater jellyfish, the atolla has a deep-red color. To go with this impressive coloration, the atolla can put on a stunning bioluminescent light show that it uses as an unusual defense mechanism.
Typically jellyfish and other animals use bioluminescence to lure their prey. However, the atolla jellyfish appears to use it to flee when threatened.
The atolla sets off spectacular flashes designed to lure in other predators when under attack. While this might sound crazy, the theory is that the new predator will attack whatever was trying to eat the atolla leaving the jellyfish to make its escape.
