some of these rose shapes corals are more than two metres wide and the whole reef structure stretches three kilometres along the seabed. its depth and its distance from the coast is thought to be a key reason for its pristine condition. the researchers say it shows no signs of damage from pollution orfrom warming ocean temperature, something that poses a major threat to swallower reefs. it looks beautiful but scientifically, how important is this as a discovery? it might be today one of the largest coral reefs in the world that actually lies at that sort of depth of more than 30 metres so from that perspective, this is opening a new insight in science. this could suggest that we have many more large reefs in our ocean at depths beyond 30 minutes which we simply do not know about. it is often said we know more about the surface of the moon than we do about the ocean floor. only about a fifth of it has so far been mapped. this discovery is part
