Coral reefs are structures that generate in warm ocean biomes. They consist of multiple clusters of coral blocks, coral and coral fans. These clusters come in a wide variety of shapes, sizes, and colors, ranging from a few blocks of brain coral on the ground to large tree-like structures of fire coral.
Generation[]
Coral reefs generate throughout warm ocean biomes (though not deep warm oceans), densely covering the sea floor. Coral reefs generate at constant elevation y level. Although they can generate on underwater ravine floors, they do not generate on deep ocean floors.
In Bedrock Edition, the coral reef structures are stored in the coralcrust
folder.[more information needed] Therefore, players can manually load every piece of coral reef structure using structure blocks, for example: coralcrust/outcropping1
loads one of coral reef variant structure.
Structure[]

Coral reef structure
A coral reef consists of a few clusters of coral blocks, each of a particular type. Sometimes, these clusters include dead coral, andesite, diorite, or granite blocks.[Bedrock Edition only]
Coral reefs are usually topped with coral, and sometimes coral fans and sea pickles. The coral and coral fans are not necessarily the same type of coral as their support blocks; in fact there are often multiple types on the same reef. In Bedrock Edition, coral reefs occasionally include dead coral fans.
