In what has been described as the “world’s biggest orgy”, coral on Australia’s Great Barrier Reef has spawned in one of nature’s most amazing and rarely-seen shows. In an even rarer occurrence, the coral put on an encore performance, re-producing - or spawning - for the second time in two months, releasing millions of eggs and sperm into the waters of the Great Barrier Reef to fertilise. This almost unseen “split-spawning” event had marine scientists and tourists marvelling in delight.
