A giant-sized deep-sea coral reef has been found off the U.S. coastline

The new map made by the experts revealed thousands of previously unknown deep-sea corals, which are also known as cold-water corals. As scientists noticed, they are spread over an area of 2.6 million hectares at depths ranging from 500 to 1,000 meters. The largest cluster of corals was recorded in an area called the Thousand Hills, which stretches 254 kilometers long and 42 kilometers wide.
