Underwater microscope documents coral behaviour
A paper in the journal Nature Communications reports on the results of Benthic Underwater Microscope (BUM). The device, designed by Scripps Institution of Oceanography was deployed in the Gulf of Eilat and produced imagery of corals apparently “embracing” and turf wars between coral polyps. The microscope was also able to capture recently bleached living coral being colonised by algae when it was used at Maui, Hawaii.
