Natures beauty - Living Lights
From Fireflies, To Squid to Mushrooms to a whole part of the ocean that glows only on one day, to freaky glowing string hanging down the ceeling - all these are self glowing creatures that - without power - light up their environment to fend of prey, attract prey, attract mates or have some unknown purpose - have a look at them over at Curious Expeditions and lots of more amazin photos and videos of living things that just light up.
