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).
Ocean acidification may also have an effect of 'gender discrimination' as spawning female corals are significantly more susceptible to the negative effects of ocean acidification than spawning male coral [73] Bamboo coral is a deep water coral which produces growth rings similar to trees. The growth rings illustrate growth rate changes as deep ...
This sewage can reach waterways through storm water, leaks, or direct dumping of human sewage into bodies of water. The next biggest sources come from agricultural practices. Chemical fertilizers used in farming can seep into ground water or be washed away in rainwater, entering water ways and introducing excess nitrogen and phosphorus to these ...
Primnoa pacifica is a deep water coral, some of which can survive at depths as great as 6 kilometers and temperatures as low as 30 °F. [3] Primnoa pacifica is typically found along North Pacific outer continental shelves and inner continental slopes ranging in depths of 150 meters (490 ft) and 900 meters (3,000 ft).
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 ]

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 ...
