Sea of Amami: Miraculous Coral Reefs

Synopsis
First-ever 8K images of spawning coral and mystery circles

The breathtaking coral reef in the sea of Amami, off Kagoshima in southern Japan, is a world-class gem. It is home to 400 species of coral, where an abundance of colorful fish find shelter. Also inhabiting the area is the newly discovered white-spotted pufferfish, noted for its peculiar behavior of creating sand circles on the seafloor. The reef is a miracle in other ways, too. 15 years ago, a devastating rise in water temperatures and damage from coral-eating starfish pushed the reef to near total collapse. Now, following a recovery with speed that surprised everyone, the corals' great spawning is about to begin.
