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).
Because it is difficult to access deep sea corals for study, relatively little is known about the microbiome of P. arborea. It has been found to have a host-specific microbiome and an external surface mucopolysaccharide layer (SML), which is a mucus that acts as a defense against water-borne pathogens and helps the coral filter feed.

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.
The classification of corals has been discussed for millennia, owing to having similarities to both plants and animals. Aristotle's pupil Theophrastus described the red coral, korallion, in his book on stones, implying it was a mineral, but he described it as a deep-sea plant in his Enquiries on Plants, where he also mentions large stony plants that reveal bright flowers when under water in ...
Scientists have mapped the largest coral reef deep in the ocean, stretching hundreds of miles off the U.S. Atlantic coast. While researchers have known since the 1960s that some coral were present ...
The Miami Terrace and other areas of deep sea coral can be damaged by certain kinds of fishing gear such as bottom trawling or dredging. [8] Areas on the Miami Terrace and a series of biogeographically similar areas were approved in 2004 for protection from these activities through the South Atlantic Fishery Management Council but were never finalized.
The world’s largest deep-sea coral reef has been discovered off the East Coast: a massive 6.4 million acre seascape that stretches from Florida to South Carolina, according to National Oceanic ...
[4] [5] The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 160 kilometres (100 mi) wide in places and over 61 metres (200 ft) deep. [6] The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. [7]
