In September 2012, a story began circulating about underwater “crop circles”. Photographer Yoji Ookata discovered them near Amami Oshima at the southern tip of Japan, and later brought back a film crew and others to study them.
The mystery circle as it was first called was more than six feet (~2 m) in diameter and contained intricate patterns of ridges radiating out from the center.
The unexpected artist of this sand circle was found to be a tiny male puffer fish. It spent days and nights to make the circle using only a flapping fin to attract a mate. After completing the circle the fish actually decorated it with broken pieces of shells. Females who mated with the male laid their eggs in the center of the circle.
“When a massive power outage struck southern California in the 1990s, Los Angeles residents reportedly called 911 to express alarm about strange clouds hovering overhead; they were seeing the Milky Way for the first time.”
