About 80-90% of oceanic creatures create light. Bioluminescence has evolved differently for each creature some use it as a scream for help against predators, casting unwanted attention
Bioluminescence is one of my favourite things about marine life. The beauty of seeing tiny particles of light dripping off bow-riding dolphin in the middle of the night in the Caribbean sea, or night diving and turning off your flashlight to see your body agitate and light the bioluminescent organisms. It is like nothing else in this world. The ocean is truly an alien environment, and I am so lucky to have been able to experience these amazing light displays in person.
