The next great improvement in CD & DVD technology may come from the eye of a shrimp. In addition to trinocular vision and the ability to see in 12 colors (humans are limited to binocular vision & 3 colors), the mantis shrimp is the only animal known to be able to see circularly polarized light, which travels in the shape of a helix rather than in straight lines. The light-sensitive cell that allows the shrimp to do this outdoes synthetic wave plates found in CD and DVD players and camera filters that convert circularly polarized light to linear form. And the cell can detect ultraviolet light, as well. Engineers are trying to mimic the mantis shrimp’s superior technology using liquid crystals. "The cool thing is I think it's actually something you could make and it would improve the workings of current technologies such as Blu-Ray, which uses multiple wavelengths of light, and of future data storage devices," said the biologist who discovered the shrimp’s giant abilities.
