From Fortune:

The largest deep-sea coral reef has been mapped off the U.S. Atlantic coast, spanning 310 miles long and 68 miles wide. Discovered using new underwater mapping technology, it extends from Florida to South Carolina. This vast habitat provides homes for a variety of marine life at depths ranging from 655 to 3,280 feet. More deep-sea reefs are likely to be found as ocean mapping technology improves.
