The Census of Coral Reefs (CReefs) is a field project of the Census of Marine Life that surveys the biodiversity of coral reef ecosystems internationally. The project works to study what species live in coral reef ecosystems, to develop standardized protocols for studying coral reef ecosystems, and to increase access to and exchange of information about coral reefs scattered throughout the globe.
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
While it covers only 1.6% of the planet's oceanic area, the region has 76% of all known coral species in the world. As a habitat for 52% of Indo-Pacific reef fishes and 37% of the world's reef fishes, it contains the greatest diversity of coral reef fishes in the world [17] More than 3,000 species of bony fish are distributed over more than 90% of the Coral Triangle.

The Ocean Portal represents the third pillar of the National Museum of Natural History's Ocean Initiative, created to further the museum's mission to ...
The densest and most spectacular reefs, along with the highest water clarity, are found to the seaward of Key Largo (in and beyond John Pennekamp Coral Reef State Park) and Elliott Key (the northernmost 'true' Florida Key) where the two long keys help protect the reefs from the effects of water exchange with Florida Bay, Biscayne Bay, Card ...
Map of the Amazon Reef, relative to Brazil, French Guiana and Suriname, with main reef structures highlighted in orange. The Amazon Reef, or Amazonian Reef, [1] is an extensive coral and sponge reef system, located in the Atlantic Ocean off the coast of French Guiana and northern Brazil.
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
