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 ...
Ocean acidification is a global threat to coral reef ecosystems. [26] Based on the biodiversity in the Coral Triangle area, damage will come to many sectors, because the coral reef is a fundamental ecosystem in the coastal area. Started by rising levels of atmospheric carbon dioxide, the calcium carbonate decrease then enhances bioerosion and ...
About 25% of the ocean's fish depend on healthy coral reefs Coral reefs cover only a tiny area of the ocean floor — about 1% of the total marine habitat — but, like bustling cities, they ...
The Great Barrier Reef is the world's largest coral reef system, [1] [2] composed of over 2,900 individual reefs [3] and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).
Kenn Reefs, submerged atoll of about 15 by 8 km, area 40 km 2, islet Observatory Cay in the Southeast, 2 m high; Saumarez Reefs, southernmost reefs to be located on the Coral Sea Shelf; three main reefs and numerous smaller reefs that form a large crescent-shaped formation open to the northwest, about 27 by 14 km, area less than 300 km 2. There ...
The Miami Terrace Reef 1] is a coral reef off the coast of Florida stretching from South Miami to Boca Raton, in the Atlantic It lies in depths of 650 to 2,000 feet (200 to 610 m) on top of a geological formation known as the Miami Terrace, a 40-mile (65 km) long shelf about 15 miles (24 km) off shore.

A narrow strip of sand, some beach scrub and a few lonely trees did almost nothing to slow the ocean swells as they collapsed houses and ripped others from their foundations, killing a 13-year-old girl and her father. But after years of work, a system of artificial reefs largely completed this summer could help soften the blow of future hurricanes.
