Clip: Season 38 Episode 7 | 2m 57sVideo has Closed Captions
This event contributes to the growth of the largest living structure on Earth.
On nights when the perfect tide conditions, day-length and sea temperature all align, some 400 species of coral across 3,000 reefs reproduce by releasing their eggs and sperm simultaneously. This ultimately helps grow the world's largest living structure - the Great Barrier Reef.
