Coral reef community. Coral reefs are extensive and diverse marine ecosystems. Corals themselves are tiny animals that live in colonies. Corals may be soft or hard (strengthened by secretions of calcium carbonate) Coral reefs are made up of hard and soft corals,sponges,ascidian and algae,all combining to hold the physical structure of the reef together.
