'''Coral reefs''' are [[Minecraft:feature]]s that generate in [[Minecraft:warm ocean]] [[Minecraft:biome]]s. They consist of multiple clusters of [[Minecraft:coral block]]s, [[Minecraft:coral]], and [[Minecraft:coral fan]]s. These clusters come in a wide variety of shapes, sizes, and colors.

== Generation ==
[[File:Coral Reef 18w14b.png|thumb|240x240px|Coral reefs]]
=== ''Java Edition'' ===
The distribution of coral reefs is noise-based, which means that in some places of [[Minecraft:warm ocean]] floor, the reefs are distributed densely, and in other places there's no coral reef at all.{{info needed|How does this noise work? Is there a visualizer for this like with Chunkbase?}}

There are three types of coral reefs: coral tree, coral claw, and coral mushroom. Coral tree has a main trunk and two to four branches that tend to point upward. Coral claw has two to three branches that tend to point horizontally. Coral mushroom looks like a small hut or a domed building.

All these three types consist of [[Minecraft:coral block]]s, [[Minecraft:coral]], [[Minecraft:coral fan]]s and [[Minecraft:sea pickle]]s.

[[Minecraft:Seagrass]] and [[Minecraft:sea pickle]]s can generate on coral blocks because they are generated later than coral reefs. Coral reefs may have several sea pickles on them, but not all sea pickles on them belong to the coral reef feature.

=== ''Bedrock Edition'' ===
{{IN|be}}, coral features densely cover [[Minecraft:warm ocean]]'s floor, and there are two types of coral features: huge coral and small coral.

There are two types of huge coral: coral (coral reefs) feature and coral crust feature. Coral feature comes in four varieties of shapes, including small clump, tree-like coral, craw-like coral, and coral spire. Coral crust feature is a huge pile of blocks including [[Minecraft:coral block]]s, [[Minecraft:dead coral block]]s, [[Minecraft:andesite]]s, [[Minecraft:diorite]]s, [[Minecraft:granite]]s and [[Minecraft:sand]]s. Both types of huge coral have some [[Minecraft:coral fan]]s attached to them. Unlike {{el|je}}, there are no sea pickles in these features; however, [[Minecraft:Vegetation#Underwater|seagrass feature]] and [[Minecraft:Vegetation#Underwater|sea pickle feature]] can also generate on them.

There are two types of small coral: sea anemone feature and coral hang feature. Sea anemone feature consists of [[Minecraft:coral]] and [[Minecraft:coral fan]]s, generating attached to the top surface of blocks that are not lower than 16 blocks below the sea level (Y>=48). Coral hang feature consists of [[Minecraft:coral fan]]s, generating attached to a side surface of blocks that are not lower than 14 blocks below the sea level (Y>=50).

== Structure ==
{{exclusive|bedrock|section=4}}
{{IN|bedrock}}, coral crusts are generated with structure files, which are stored in the <code>behavior_packs/vanilla/structures/coralcrust</code> folder.

''The [[Minecraft:Structure Block|structure blocks]] do not appear in the final generation.''
