Deep-sea corals are members of the Class of animals called Anthozoa, which among other creatures, includes sea anemones, stony corals, soft corals and sea pens. Deep-sea corals inhabit the colder deep waters of our continental shelves and offshore canyons in waters ranging from 50-1000 m depths. Where current and substrate conditions are suitable, these corals form thickets or groves of high complexity. Similar to the ancient redwood and sequoia trees, these animals are slow growing and can reach hundreds of years in age. Similar to tropical rainforests, they also provide habitat for many other animals. Deep-sea corals may provide historical clues to climate change and may also be the source of new drugs from the sea.

Deep-sea corals from about 400 meters off the coast of the Hawaiian Islands are much older than once believed and some may be the oldest living marine organisms known to man.
