Explore the rainforests of the sea—coral reefs that support 25% of marine species despite covering less than 1% of ocean floor. Study how coral polyps build calcium carbonate structures over centuries, creating underwater cities for fish, crustaceans, and countless organisms.
Learn about symbiotic relationships (clownfish and anemones), reef ecosystems' nutrient cycling, and threats like bleaching from warming oceans. Watch documentaries (Blue Planet, Chasing Coral), read marine biology books, snorkel/dive if able, or visit aquariums with reef tanks. Understanding reefs reveals marine biodiversity, highlights conservation urgency, and inspires ocean protection.
Reefs face existential crisis—knowledge motivates action.
