Undersea Coral Spawning in Okinawa - HD stock video

Pan up from a coral reef to get a view of a myriad of eggs rising from it. Eggs in the water. Pan down to the coral reef. Different species of coral of the Acropora genus in Oura Bay off Nago City, Okinawa Prefecture simultaneously spawning at night. The depth is a relatively shallow 5 m. The myriad of grain-like objects are bundles of egg and sperm. These bundles rise to the surface of the water, where fertilization takes place. The bundles drift for some time and then sink to the bottom of the sea where they will form new coral reefs. Oura Bay is situated off Nago City on the eastern side of Okinawa's main island. The bay is home to over 5,800 species of fauna. It is one of the most biologically diverse parts of Okinawa.
