A middle school student cleans algae from a coral tree in the Coral Restoration Foundation’s offshore nursery in the Florida Keys. These coral trees allow the polyps in the fragments to feed freely from the plankton floating by them in the currents. Exposure to sunlight and their natural diet allows them to grow large enough to be outplanted on the reef - meaning they are taken to a wild coral reef nearby and cemented to areas that previously had living coral.
