I have been lucky enough to photograph two examples of bio-luminescence in nature. The first was Omphalotus nidiformis, or ghost fungus. This was growing in the Mogo area just south of Batemans Bay in NSW, Australia. The other example involved blue bio-luminescence or sea sparkle caused by billions of single-celled algae or plant plankton called Noctiluca scintillans. To seee this, I did a 400 km round trip with a friend from Canberra to Jervis Bay in NSW to photograph the algal blooms seen there in May 2019.
