Coral Reef Facts
25% of ocean species depend on coral reefs despite covering less than 1% of ocean floor. Corals are animals related to jellyfish. Symbiotic algae give color and provide 90% of energy. The Great Barrier Reef is 1,400 miles long, visible from space. About 50% of reefs have died since 1950. The Coral Triangle has 76% of all coral species. Recovery from bleaching takes 10-30 years.
