Now, new research reveals surprising results: up to 80 percent of ray-finned fishes living in the open water—from deep-sea-dwelling anglerfish to coral-reef-residing flashlight fish —make their own light. What's more, the phenomenon has evolved independently in that group 27 times.
Do fish communicate with bioluminescence?
Scientists have shown for the first time that deep-sea fishes that use bioluminescence for communication are diversifying into different species faster than other glowing fishes that use light for camouflage.
Why are some fish fluorescent?
Gruber and Sparks speculate that fish fluorescence is a way for the fish to communicate within and between species . “The ones that are biofluorescent are [mostly] the cryptically colored fish,” said Sparks. To an organism that can visualize it, “these fish must stick out like a sore thumb.”

The company can snip the “glow gene” out of the coral and stick it into the genes of a zebra fish embryo . This produces an animal that will definitely get your neighbors talking about your aquarium.
How do phosphorescent materials work?
How It Works – Simple Explanation. Basically, a phosphorescent material is “charged” by exposing it to light . The material absorbs light and releases the stored energy slowly and at a longer wavelength than the original light.
What does bioluminescence look like?
Most marine bioluminescence, for instance, is expressed in the blue-green part of the visible light spectrum . These colors are more easily visible in the deep ocean. Also, most marine organisms are sensitive only to blue-green colors. They are physically unable to process yellow, red, or violet colors.
How do fish glow?

Flashlight fishes have special pouches of glowing bacteria under their eyes. When they want to turn on their lights, they lower folds of skin below each eye.
Are humans bioluminescent?
