The hard coral polyp makes the coral
Coral reef
the adaptations in the coral reef are to ajust to the water and sharks!!!
The reef-building coral on the Great Barrier Reef is primarily in the polyp stage. Corals are marine animals that belong to the class Anthozoa, and they exist as polyps, which are small, cylindrical structures that anchor to the sea floor and form colonies. Medusa is the free-swimming stage of some jellyfish and is not associated with coral formation. Therefore, it is the polyp stage that contributes to the growth of coral reefs.

It had to start photosynthesis.
a coral reef is not one big animal, it is a bunch of small coral polyps growing on top of each other. the outer layer are the live polyps (coral is an animal) and they are on top of the dead coral skeletons. a coral polyp does not have a backbone because it is an invertebrate of cnidaria phylum. it has a skeleton made of calcium carbonate, or carbon and calcium. neither one coral polyp has a backbone and a coral reef does not have a backbone either.

No its animal to coral
Corals are hard because the individual animals, called polyps, each secrete calcium carbonate which hardens into a shell around each polyp.
Most coral reef animals, making up the reef itself, are filter feeders and they eat the microorganisms that live in the water surrounding them.
