Australia's Great Barrier Reef is playing home to what can be called world's biggest orgy in the world.
A video non pornographic and visually beautiful and rarely-seen reproduction of sea, and has attracted tourists from all over the world, the Mirror reported.
It was the 2nd time in two months that the Great Barrier Reef spawned overnight releasing millions of eggs and sperm into the waters to fertilise, and Professor Jamie Seymour of James Cook University said that the conditions have to be perfect for the coral to spawn, which is generally between November and December.
The Great Barrier Reef has the most diverse coral system and spawning off the Queensland coast involves 60 per cent of the types of corals on the reef.
