This explosion of life where coral branches release into the sea millions of sperm and eggs in perfect sync, is a natural firework display.

The Australian Great Barrier Reef is the largest in the world, covering an area of over 80 square miles and the true phenomenon here is that only one in ten million eggs are able to be fertilized. This fertilized egg will be transported by currents, then fixate on a rock where it will then turn into an octopus and separate itself to give rise to a new colony.
