A new study investigates why gorgonian corals, which can
form a ‘canopy’ over reefs, appear to be proliferating in certain places
As Earth’s temperature climbs, the stony corals that form
the backbone of ocean reefs are in decline.
It’s a well-documented story: Violent storms and coral
bleaching have all contributed to dwindling populations, and increasing acidity
of seawater threatens to take an additional toll.
Less discussed, however, is the plight of gorgonian corals —
softer, flexible, tree-like species that can rise up like an underwater forest,
providing a canopy beneath which small fish and aquatic life of all kinds can
thrive.
