This amazing photo was taken in southern Tasmania by Dave Reynolds. This phenomenon is called Bioluminescence, in which the organisms produce light through a chemical reaction in their bodies. For this reaction to occur, an organism has to contain luciferin, in which it produces light when it reacts to oxygen. The beauty of this image resembles in the bright blue light that occurs from chemical reaction Vs. photons released from the surface of stars.
