The midwater region of the ocean houses the largest ecosystem on Earth. This region, which forms the link between the ocean surface and the bottom, is enormous — with depths ranging from 200 to 11,000 meters. Many of the inhabitants of this vast area have evolved peculiar abilities and features that allow them to survive. This includes camouflaging their bodies in darkness and in light.

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
