About Coral Reef
What are coral reefs made of?
Coral reefs are built by tiny animals called coral polyps that secrete calcium carbonate to create hard skeletons. Over thousands of years, these skeletons accumulate to form massive reef structures that can be seen from space.
How many species live in coral reefs?
Coral reefs support about 25% of all marine species despite covering less than 1% of the ocean floor. A single reef can host over 4,000 species of fish, plants, and other creatures.
Where are the world's largest coral reefs located?
Australia's Great Barrier Reef is the largest coral reef system, stretching over 1,400 miles. Other major reefs include the Belize Barrier Reef, Red Sea coral reefs, and Caribbean reef systems.
How do coral polyps get their bright colors?
Coral polyps get their vibrant colors from tiny algae called zooxanthellae that live inside them. These algae provide food through photosynthesis and give corals their beautiful yellow, brown, and green hues.
What threats do coral reefs face?
Coral reefs face dangers from climate change, ocean acidification, pollution, and overfishing. Rising water temperatures cause coral bleaching, where stressed corals expel their colorful algae partners and turn white.
How fast do coral reefs grow?
Coral reefs grow very slowly, typically only 1-2 centimeters per year. The massive reef structures we see today took thousands of years to develop, making their protection critically important for future generations.
