The'song' of coral reefs changes with the Moon - Nature. The biological activity of fish and invertebrates that live among the corals changes.
This is demonstrated by a study conducted in Hawaii by researchers from the Naval Undersea Warfare Center of the United States Navy. The findings demonstrate that diverse communities of coral reef organisms react rapidly to nocturnal variations in ambient light. The advantage of acoustic monitoring lies in the fact that the organisms that populate the coral reef emit sounds continuously, even during the night when the darkness prevents conducting visual inspections.
