Red coral necklaces fill a store display window. The United States annually imports around one million live coral animals from tropical reefs for use in aquariums, and is the largest documented...
New, white growth emerges from a living deep-sea coral sample that was stained pink, enabling ocean scientists to measure its coral growth rate. Find out more about how ocean scientists study deep-...
