Looking more closely, divers found a small puffer fish was responsible for these works of masterful art and managed to film the artist in action!

This fish created these sand sculptures to attract potential partners . Scientists have observed that over the nesting area , the more likely it is to attract the attention of females . The females swim amid these geometric figures and lay their eggs in the center of the nest .

Scientists have discovered that complex patterns have a hydrodynamic effect! The ribs and grooves help to minimize the current in the center of the nest , which protects the eggs turbulence and protect them from predators .
