Discoveries show these low light reefs may serve as refuge for some species
NOAA-supported scientists working in the Hawaiian Archipelago are calling some of the deep coral reefs found in the region’s so-called oceanic “twilight zone” the most extensive on record, with several large areas of 100 percent coral cover. They also found that the deep coral reefs studied have twice as many species that are unique to Hawaii than their shallow-water counterparts.
