Facts about Deep-sea Coral
- 06
Manganese oxide deposits accumulate on deep-sea coral skeletons at measurable rates, allowing scientists to date coral growth patterns and reconstruct historical ocean chemistry over millennia.
- 05
Black coral species in the genus Leiopathes can live for over 4,000 years, making them among the longest-lived animals on Earth.
- 04
Octocorals and stony deep-sea corals lack the symbiotic zooxanthellae algae that shallow-water corals depend on, instead filter-feeding on marine snow and organic particles from above.
- 03
Tropical cyclones can trigger coral bleaching in deep-sea corals at depths exceeding 200 meters through rapid pressure and temperature changes in ocean water columns.
- 02
Lophelia pertusa, the most studied deep-sea coral species, survives in near-freezing waters between 400 and 2,000 meters deep across the Atlantic Ocean.
- 01
Some deep-sea coral species grow less than one millimeter per year, making a colony reaching three meters tall potentially over 4,000 years old.
