Coral reefs are the basis of a very large ecosystem; they have the highest biodiversity of any marine ecosystem. More than 25 percent of all known ocean fish live in coral reefs and many more marine organisms live inside the coral. There are nearly a million species of fish and other marine life that make up the ecosystem of coral reefs. Coral reefs are often called the “rainforests of the ocean” because of its amazingly diverse ecosystem.
