A Tetraodon uses sand to make underwater art. Mysterious geometric shapes were observed on sandy bottoms of Amami Oshima by 24 meters deep in the south of Japan. 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 .

PaybackI wonder if they all have 26 troughs around the edge, or this guy just happened on that number.

jonnyI'm not necessarily calling bs on this, but I'd be a lot more inclined to believe what is being presented if I saw it from the beginning, instead of just a fish moving around what looks to be a pre-constructed piece. It looks a lot like any number of fish species that move in similar patterns around dense reefs.
eric3579Not sure if this has the information you're looking for but it seems like it takes close to a week to build one of these(from the pics and the dates the pics were taken).
Lots of additional info here.
