Corals are not only found in shallow tropical waters, but in cold, dark, deep areas of the sea. Amazing coral forests are found at depths of 60-3,050 meters (200-10,00 feet). They support an abundance of marine life but are in peril from threats such as ocean acidification and bottom trawl fishing...
