A cuttlefish can reproduce the texture of a gravel bed on its skin — in complete darkness. Chameleons change color not primarily to hide, but to communicate. A stick insect's body plan is so precise that its eggs mimic seeds, tricking ants into carrying them to new locations. Camouflage is not a coat of paint; it is a complete biological system built by evolution over hundreds of millions of years.
