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. Learn more in the multimedia feature "Coral Gardens of the Deep Sea."
