Mystery circles under the sea

a scuba diver recently found these mysterious patterns on the ocean floor, off one of the islands in Japan. no one had ever seen them before.

he enlisted some help from colleagues, who brought their underwater cameras to try and catch the artist at work. and guess who they found? this little guy!

he's a puffer fish, and these amazing installations are part of his mating ritual. females are attracted to the ridges and swim into the center, where they mate and lay the eggs. here's the little guy hard at work!

he also collected shells to decorate the installation, which later would be used as nutrients for the babies. the ridges also protect the eggs from being tossed about by the underwater currents. isn't that amazing? the link has more pictures and explanation. the animal kingdom is so incredible.
