Plate coral (Acropora sp.) silhouetted against the Sun on a coral reef. Hard corals such as this comprise tiny organisms which build rocky structures around their colonies for protection and support. They feed by filtering plankton from the water. Coral reefs provide a basis for diverse marine ecosystems. Photographed in Layang Layang, Malaysia.
