Etter at en hadde laget kunstige metamaterialer, har en oppdaget flere og flere naturlige materialer som oppfører seg som metamaterialer. F.eks. [[opal]], [[perlemor]], Aphrodita aculeata pigger, det [[ytre skjelett]]et til visse [[biller]].<ref>[http://news.bbc.co.uk/2/hi/science/nature/1099278.stm BBC News: 3 January, 2001, Sea mouse promises bright future] Citat: "...The sea mouse, or Aphrodita, has spines that normally appear deep red in colour. But when light falls on a spine perpendicular to its axis, stripes of different colours appear – strong blues and greens..."The simple structure responsible for this effect is a remarkable example of photonic engineering by a living organism."..."These structures may have application in photonic communications, where there is much interest in fabricating [[Fotonisk fiber|photonic crystal fibres]] with similar morphology."..."</ref>
