The Great Barrier Reef, the world's largest coral reef system, stretches over 2,300 km (1,430 miles) along the coast of Australia.

Some coral species can live for over 4,000 years, making them among the longest-living organisms on Earth.

Fun Facts

💡 1

The colors of coral reefs are mostly due to the algae living inside the coral, not the coral itself.

💡 3

Coral reefs are sometimes called the 'rainforests of the sea' because of their high biodiversity.
