Coral reef research. Close-up of a coral exoskeleton, showing structures known as septa and calices. Details of these structures can be used to identify coral species. Corals are microscopic marine polyps that form colonies and secrete minerals to build the exoskeleton structure seen here. This coral exoskeleton is being studied as part of research into coral reefs. Photographed at the University of Newcastle, UK.
