8 Beautiful Bioluminescent Creatures From the Sea
While a handful of land animals can create their own light, homemade luminescence is the rule rather than the exception in the open ocean’s dark waters.
Researchers estimate that between 80 and 90 percent of deep-dwelling animals are bioluminous, creating light by mixing the pigment luciferin with luciferase, the enzyme that makes it glow. The light tends to green and blue, colors that travel far in seawater. Glowing helps attract mates, lure prey or confound predators.
