Mysterious geometric “crop circles” – some as large as six feet in diameter 80 feet below the surface – were recently observed on the sandy seabeds of Amami Oshima in Southern Japan. Upon closer inspection, divers discovered that a small pufferfish was responsible for these masterful artwork! Amazing video has surfaced of the artist in action.
Male puffers create these sand sculptures to attract potential mates. Scientists observed that the larger the nesting area, the greater the chance a male would attract the attention of females. Females will swim to the middle to consummate with the artist of their liking then lay her eggs in the center of the nest.
Even more amazing, these “crop circles” are more than just showsmanship. Scientists discovered the intricate patterns have hydrodynamic purpose! The ridges and grooves help to minimize ocean current at the center of the nest, thereby protecting the eggs from turbulence and the likely protecting its occupants from predators.
Sealife is just way too cool.
