20-year study of deep reefs finds algae meadows and swaths of continuous coral with the highest rate of species found nowhere else in Earth’s seas

The “twilight zone” of Hawaii’s deep coral reefs are home to vast algae meadows and support the highest rates of species found nowhere else in Earth’s seas, scientists have discovered.

A 20-year study of the archipelago’s poorly-explored mesophotic – middle light – coral zone also found the deep-reef habitats are home to many unique and distinct species not found on shallow reefs with vast areas of 100% coral cover.
