April 25, 2016 - What do biofluorescent sharks see through their eyes? The recent discovery of more than 200 biofluorescent marine creatures has sparked interest in the biological and ecological roles of this phenomenon. Marine biologist and National Geographic Emerging Explorer David Gruber delves into the study of how these creatures see by designing a "shark-eye camera" that replicates the vision of biofluorescent sharks. Gruber enters the deep waters of Scripps Canyon, off the coast of Southern California, to image glowing swell sharks without the aid of artificial light. The resulting footage shows that swell sharks see each other's biofluorescent markings much better than other objects in the dark, blue sea.
