*[http://news.bbc.co.uk/1/hi/sci/tech/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 photonic crystal fibres with similar morphology."..."

The phenomenon can be observed in a new class of optical fibers, called photonic crystal fibers. PCFs consist of a tiny solid glass core surrounded by a cladding, or casing, that contains air holes along the length of the fiber...As the IR light propagates, or spreads, through a 1-meter-long fiber, the light appears, first orange, then yellow and finally green...The visible lightwaves emerge from the fiber as white light, which contains all the colors of the spectrum..."
