The cuttlefish, also known as the “chameleon of the sea,” can rapidly change both the color and pattern of its skin, helping the creature blend in with its surroundings to avoid predators. And, scientists said in the study that they have identified new details of the “sophisticated biomolecular nanophotonic system,” which is responsible for the cuttlefish's color-changing ways. The cuttlefish is part of the cephalopod family, which includes better-known marine animals like the squid and octopus.
“Nature solved the riddle of adaptive camouflage a long time ago,” Harvard's Kevin Kit Parker said in a statement. “Now the challenge is to reverse-engineer this system in a cost-efficient, synthetic system that is amenable to mass manufacturing.”
