| New way fish camouflage themselves in the ocean: Manipulating how light reflects off skin Posted: 03 Jun 2013 11:23 AM PDT Researchers found that lookdown fish camouflage themselves through a complex manipulation of polarized light after it strikes the fish skin. In laboratory studies, they showed that this kind of camouflage outperforms by up to 80 percent the "mirror" strategy that was previously thought to be state-of-the-art in fish camouflage.  |
