About Coral Reefs

Coral reefs are aragonite structures produced by living organisms, found in marine

waters with little to no nutrients in the water.In most reefs, the predominant

organisms are stony corals, colonial cnidarians that secrete an exoskeleton of

calcium carbonate. The accumulation of skeletal material, broken and piled up by

wave action and bioeroders , produces a massive calcareous formation that

supports the living corals and a great variety of other animal and plant life.
