'Full of life': scientists discover pristine deep-sea Galapagos coral reefs – video

Scientists operating a submersible have discovered deep-sea coral reefs in pristine condition in a previously unexplored part of the Galapagos marine reserve. Diving to depths of 600 metres (1,970ft), to the summit of a previously unmapped seamount in the central part of the archipelago, the scientists witnessed a breathtaking mix of deep marine life. This has raised hopes that healthy reefs can still thrive at a time when coral is in crisis due to record sea surface temperatures and ocean acidification
