Artistic Fish

An underwater cameras shows an unlikely artist, a small Japanese Puffer Fish, using only his flapping fin to tirelessly carve circular ridges in the sand. The Puffer Fish, best known in Japan as a delicacy, albeit a potentially poisonous one -- even takes small shells, cracks them, and lines the inner grooves of his sculpture as if decorating his piece. Attracted by the grooves and ridges, female puffer fish find their way along the dark seabed to the male puffer fish where they mate and lay eggs in the center of the circle. In fact, scientists observed that the more ridges the circle contained, the more likely it was that the female would mate with the male. The little sea shells weren't just in vain either. The observers believe that they serve as vital nutrients to the eggs as they hatch, and to the newborns.
