A study released Thursday says that two ocean fish - the big-eyed scad and the lookdown - have fine-tuned a method of avoiding predators by hiding in light. Elements in their silvery skin render them nearly impossible to see. The U.S. Navy funded the study as part of an effort understand how fish do this, and how it could be used to the navy's advantage.
The University of Texas study, published in the journal Science, said the fish use their skin as camouflage to blend in with light waves. They've evolved a microscopic element on the surface of their skin called guanine platelets.
For years, the navy has searched for ways to hide vessels in deep open water. The study's findings brings the military branch one step closer to understanding a new type of camouflage. How and when that could happen are questions with answers far in the future.
