Life under water throws up fascinating phenomenona from time to time. This is one such incident.You might be amazed to know who the artist behind this masterpiece is.Without further ado let me tell you, this crazy sea-bed art is courtesy the super-cute puffer-fish.

How were these masterpieces discovered?

In 1995, a few divers noticed a beautiful, strange circular pattern on the seafloor off Japan. Gradually, more circles were discovered nearby. But even after their discovery, these "underwater crop circles" remained a mystery for nearly a decade since their origins couldn't be determined.

A symbol of passion

It was in the year 2011 that the real artist behind these magical patterns - a male puffer-fish -- was finally caught in the act.Scientists were amazed to know that these elaborate designs were sculpted by these five-inch long male fishes to woo their females counterparts.

Laborious love

Male puffer-fishes take seven to eight days to make these formations which measure about 2 metres (7 feet) in diametre. Aesthetics are clearly important as once the circles are finished, females come to inspect them. If they like what they see, they reproduce with the males. Another challenge faced by the male fish is to keep these patterns in place, fighting against the restless currents.
