Deep below the ocean’s surface, some corals emit an otherworldly glow called fluorescence, but for years, scientists have wondered about the purpose of these glowing colors. Among the hypotheses biologists have proposed is that fluorescence might optimize photosynthesis, shield against the sun’s radiation, protect plant-eating marine life that lives among the corals, or attract algae that live inside the coral and provide them with energy through photosynthesis. Now, researchers have come up with a different hypothesis: fluorescence attracts the plankton that corals capture and eat.
