Australian scientists have discovered hundreds of new coral and marine species on the Great Barrier Reef and Ningaloo Reef which they say will improve monitoring reef biodiversity and the impact of climate change. Three expeditions to the reefs over four years to collect the first inventory of soft corals, found 300 soft corals of which 130 were new species, said a report released on Friday.
