Coral reefs are made up of invertebrate animals known as coral polyps. These are actually transparent animals related to jellyfish. Where do corals reefs get their color?
Answer The algae they feed on
The brilliant colors coral reefs display come from algae that lives on them and that they ingest. The algae and the coral have what is known as a symbiotic relationship.
