Coral reefs are developed by the carbonate-based skeletons of a variety of animals and algae. Slowly and over time, the reefs build up to the surface in oceans. Coral reefs are found in shallow, warm salt water. The sunlight filters through clear water and allows microscopic organisms to live and reproduce. [4]
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
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. [1] Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
Every year, reefs provide about $2.7 trillion in goods and services, from tourism to coastal protection, according to a 2020 estimate by the Global Coral Reef Monitoring Network.
The class includes important coral reef builders such as the stony corals, sea anemones, and zoanthids. The recognized orders are shown below: [4] Actiniaria – sea anemones; Antipatharia – black corals; Corallimorpharia – corallimorpharians aka "false corals" †Rugosa – rugose corals; Scleractinia – stony corals †Tabulata ...

Coral reef farming involves extracting a part of a coral colony or free-floating larvae from a reef, and growing them in a nursery until outplanting [5] would be successful. It is commonly referred to as the "gardening method" and has been compared to silviculture as a management practice that mimics natural ecosystems.
Australian researchers have found coral bleaching around six islands in the far northern parts of the Great Barrier Reef, after a government agency said last week a major bleaching event was ...
