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).

Coral Growth in Cabbage Tree Bay, NSW. Corals might evade ocean warming by migrating into what had been cooler waters. [2] The planktonic larvae of the corals could colonise suitable new areas, but for corals in places like the Great Barrier Reef; the required migration rate is about 15 km per year, which is much faster than corals can grow.

Conservation status for warm-water reef-building corals was analysed for the International Union for Conservation of Nature’s (IUCN) Red List. 44% of warm-water coral species facing extinction ...
For example, the water is colder towards the bottom of the ocean. This temperature stratification will increase as the ocean surface warms due to rising air temperatures. [5]: 471 Connected to this is a decline in mixing of the ocean layers, so that warm water stabilises near the surface. A reduction of cold, deep water circulation follows. The ...
