The Story of Coral Reefs: Rainforests of the Sea

Architects of the Ocean: Coral reefs are built by tiny coral polyps that secrete limestone skeletons, forming vast, living underwater cities.
Rainforests Beneath the Waves: Though they cover less than 1% of the ocean floor, coral reefs support about 25% of all marine species.
Symbiosis at Its Finest: Corals live in partnership with algae called zooxanthellae, which provide energy through photosynthesis and give reefs their color.
A Palette of Life: Reefs dazzle with hues of red, blue, and gold—colors produced by fluorescent proteins that protect corals from sunlight.
Ecosystem Engineers: Reefs create shelter for fish, crustaceans, mollusks, and more—each species contributing to a balanced underwater community.
Nature’s Breakwater: Coral reefs act as natural barriers, protecting coastlines from erosion, waves, and storm surges.
Medicines from the Reef
Many reef organisms produce unique chemical compounds now used in cancer, antiviral, and pain treatments.
Threatened Beauty: Rising ocean temperatures cause coral bleaching, where stressed corals lose their algae and their color—sometimes permanently.
Restoring the Reefs: Marine scientists now grow and transplant coral fragments to rebuild damaged reefs and revive biodiversity.
A Living Legacy: Protecting coral reefs preserves not just beauty, but the foundation of countless marine and human lives connected to the sea.
