Bioluminescence of Noctiluca scintillans

Recent floods in Australia has result in abundant proliferation of Noctiluca scintillans, commonly known as the Sea Sparkle resulting some breath taking Bioluminescent spectacle. For a cluster of lakes in Australia's eastern Victoria, the combination of the fire and then the rain washed ash and nitrogen-rich soil into the water. The Gippsland Lakes experienced a rise in sea level. That caused the lakes to mix with sea water, which also raised the salinity.


As you can see blow the bioluminescent brew has gaven the water a nocturnal glow.

Noctiluca scintillans  a species of algae , also called  Noctiluca miliaris, is a free-living non-parasitic marine-dwelling species of dinoflagellate that exhibits bioluminescence. The bioluminescent characteristic of N. scintillans is produced by a luciferin-luciferase system located in thousands of spherically shaped organelles, or “microsources”, located throughout the cytoplasm of this single-celled protist. Nonluminescent populations within the genus Noctiluca lack these microsources.
