Inside Bioluminescence

Did you know? An estimated 90 percent of deep-sea marine creatures are able to produce bioluminescence in some way!

Most emit blue or green hued light, though some creatures employ a red-light strategy—taking advantage of the fact that red is the first color in the spectrum to be refracted. At great depths, red is invisible to many animals, giving predators like the dragonfish who emit this color a handy advantage over unsuspecting prey.

In the deep, where food is scarce and conditions unforgiving, bioluminescence is critical to the survival of countless aquatic species.
