Pufferfish 'crop circles.' A tiny Japanese pufferfish creates a grand sand sculpture on the featureless seabed by using his fins to dig furrows. He uses this to attract the attention of passing females.
It takes him about a week to create one of the "crop circles" which run about 4 to 5 feet in diameter. He's between 15 and 20 inches long.
