A School of Snub-Nosed Darts Blends into Their Surroundings in the Great Barrier Reef

Caption

Squinting won't help you spot the fish in this photo. These snub-nosed darts blend seamlessly into their watery surroundings with help from their silvery reflective skin. Researchers have long assumed that squid, shrimp and other ocean animals could see through this disguise, thanks to an ability to detect a property of light -- called polarization -- that humans can't see. But a new study finds that not even polarization vision helps animals spot silvery fish from afar.
