The Grouper Mystery (2015)

2 /1

In French Polynesia, there is a place where every year, thousands of groupers gather in secret followed by hundreds of sharks… The photographer, diver and biologist Laurent Ballesta, with his team, wanted to better understand what motivates these fish to wait until the exact day of the full moon to spawn all at once! With the help of researchers from the CNRS of Moorea, they dived and conducted numerous experiments to study and witness this unique phenomenon. Taking advantage of this period of incredible richness, Laurent Ballesta did a record dive of 24 hours at over 20 meters.
