How some fish use polarized light to make themselves invisible to predators

You’d think there’s not much a little fish can do to hide from predators in open waters. But when rocks, algae and other marine nooks and crannies are nowhere to be found, fish turn to manipulate the physical interactions of light to balance the scale. For instance, some open ocean fish species employ specialized skin cells that reflect polarized light. This reflection is most effective, not coincidentally, at the ‘chase angle’ or from the predator’s point of view. It’s so effective that the US Navy is funding work that might shed light how exactly some fish do this and how this can be applied to make submersibles equally inconspicuous.
