In 1995, dovers discovered Incredibly intricate sand Circles scattered across the sea floor of the Amami Oshima region of Japan.
The artist of these Circles was a mystery for years, until it was revealed as the white- spotted pufferfish. Watch the pufferfish’s intricate handiwork, as the three inch long fish shovels and moves sand into a Circle that eventually reaches six feet in diameter.

Once complete, the reason for the unusual design is clear, the Circle is used to attract a female for mating and, if successful, serves as a nest for developing eggs.
