Nano Camo (IMAGE) Duke University Caption Photos from a scanning electron microscope show the brush-like array of light-absorbing structures on the leg of a midwater crustacean called Cystisoma at left, and the tiny spheres that perform the same function on the body of Phronima, another midwater crustacean. The spheres may be a colony of bacteria specific to Phronima.
