Because they don’t depend on warm water or sunlight, deep-sea corals are able to live in many different places around the world. They are far more widely distributed than scientists previously imagined—living even in waters as cold as -1ºC (30.2ºF).
For example, deep-sea corals occur in the waters of the United Kingdom, Australia, New Zealand, Canada, Ecuador, Japan, Norway, and the United States. Scientists have even found deep-sea corals off the coast of Antarctica. They grow in all the world’s ocean basins, where they form deep-water havens on continental shelves and slopes, in ocean canyons, and on tall seamounts.
