Paragorgia arborea is a species of coral in the family Paragorgiidae, commonly known as the bubblegum coral because of its bulbous branch tips. It mainly grows in depths between 200 and 1,300 metres (700 and 4,300 ft) at temperatures between 3 and 8 °C (37 and 46 °F).
How big is the newly discovered deep-sea coral reef? The reef stretches from Miami to Charleston, South Carolina, about 100 miles off the southeast U.S. coastline.
Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).
Madrepora oculata, also called zigzag coral, is a stony coral that is found worldwide outside of the polar regions, growing in deep water at depths of 50 to at least 1500 meters. [2] It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae . [ 3 ]
Studies have indicated that a seamount functions as an "oasis of life," with a higher species count and more biodiversity than the surrounding seafloor. [4] Although previous analysis has stressed the exceptionalism of the seamount habitat, recent biological analysis, much of it centered on Davidson Seamount, has indicated that this does not necessarily translate into a higher endemic percentage.
On a recent expedition, a group of ocean researchers discovered 85 miles of deep-sea coral reef off the coast of the southeastern US.
Lophelia pertusa is a reef building, deep water coral, but it does not contain zooxanthellae, the symbiotic algae which lives inside most tropical reef building corals. [6] Lophelia lives at a temperature range from about 4–12 °C (39–54 °F) and at depths between 80 metres (260 ft) and over 3,000 metres (9,800 ft), but most commonly at ...
Most of the latter are azooxanthellate and live in both shallow and deep sea habitats. In the deep sea they share the ecosystem with soft corals, polychaete worms, other worms, crustaceans, molluscs and sponges. In the Atlantic Ocean, the cold-water coral Lophelia pertusa forms extensive deep-water reefs which support many other species. [27]
