Approximately 97% of the park's area consists of sea, with more than 390 types of coral reefs decorating its seabed. The coral reefs in Bunaken are formed as part of the Indo-Pacific coral reef ecosystem, and are known as one of the highest marine biodiversity in the world. Coral Triangle: Mainly Indonesia
The impacts of reduced calcium carbonate saturation on marine calcifiers have broader ecological implications, as these organisms play vital roles in marine ecosystems. For example, coral reefs, which are built by coral polyps secreting calcium carbonate skeletons, are particularly vulnerable to changes in calcium carbonate saturation. [14]
Coral reefs cover less than one percent of the ocean floor, but have out-sized benefits for marine ecosystems and economies. A quarter of marine life will depend on reefs for shelter, finding food ...

The Structure and Distribution of Coral Reefs, Being the first part of the geology of the voyage of the Beagle, under the command of Capt. Fitzroy, R.N. during the years 1832 to 1836, was published in 1842 as Charles Darwin's first monograph, and set out his theory of the formation of coral reefs and atolls.
