Great Barrier Reef heading for the biggest spawning event on the planet

ABC

It's the world's biggest synchronised sex event that's OK to teach your kids about. Every year just after the full moon in late spring or early summer, the corals of the Great Barrier Reef release trillions of eggs and sperm into the water, usually over the course of about three or four nights. Although increasing moonlight appears to be one of the triggers leading up to the event, actual spawning for most corals begins at night before the moon rises, Professor Harrison said. "About three or four days after the full moon is usually the time of the neap tides, when there's minimal water movement," she said. "I've seen little reef fish the next morning that could hardly swim because their stomachs were so distended," Professor Harrison said.
