A silver perch does not have silver in it's skin. The shiny iridescence of the silver perch's skin and of many scaly fish skin comes from photonic crystals made of guanine. These crystals, while atomically similar to crystals grown in the laboratory, microscopically are very different and form overlapping sheets giving the crystals maximum reflectance. Most researchers believe this shiny skin evolved to fool predators by reflecting light away from the fish, especially when close to the water surface.
