What Are Corals and Why Are They So Important?
When you think of corals, you might picture colorful reefs beneath crystal-clear waters. But did you know corals are actually living animals and not just ocean rocks or plants? These tiny marine creatures play a crucial role in the ecosystem, providing shelter for thousands of species and even protecting coastlines from erosion.
In this article, we’ll explore 7 surprising facts about coral reefs that will make you appreciate them even more.
1. Corals Are Animals, Not Plants
Each coral is made up of tiny polyps that use their tentacles to catch food drifting in the water. Corals may look like lifeless structures, but they are living marine invertebrates closely related to jellyfish and sea anemones. Some coral colonies contain millions of polyps, forming vast ecosystems over thousands of years.
2. Coral Reefs Are the “Rainforests of the Sea”
Covering less than 1% of the ocean floor, coral reefs support over 25% of all marine species! That’s millions of fish, crustaceans, and marine mammals depending on reefs for survival. Losing reefs would mean a catastrophic collapse of entire marine food chains.
3. Corals Get Their Vibrant Colors from Tiny Algae
The bright colors of corals come from an algae named zooxanthellae, a microscopic algae that live inside their tissues. These algae provide up to 90% of the coral’s energy through photosynthesis. But when corals get stressed due to pollution or high temperatures, they expel the algae, turning white to become a deadly process called coral bleaching.
4. Coral Reefs Protect Coastlines from Storms and Erosion
Reefs act as natural barriers, reducing wave energy by up to 97%! Without them, coastal areas would suffer from stronger storm surges, increased erosion, and flooding. Countries with healthy reefs save billions of dollars annually in storm damage prevention.
5. Corals Glow in the Dark!
Some corals have biofluorescence, allowing them to glow in neon colors under UV light. Scientists believe this helps corals protect themselves from harsh sunlight or attract symbiotic bacteria for survival.
6. Corals Are in Serious Danger—And So Are We
Over 50% of the world’s coral reefs have already died due to climate change, overfishing, and pollution. If global temperatures continue rising, we could lose 90% of remaining reefs by 2050, disrupting global fisheries and the livelihoods of over 500 million people.
7. You Can Help Protect Coral Reefs!
Every small action counts:
✅ Use reef-safe sunscreen to prevent harmful chemicals from poisoning corals.
✅ Reduce plastic waste—millions of tons of plastic suffocate reefs every year.
✅ Choose sustainable seafood to prevent overfishing of reef species.
✅ Support coral restoration projects—many organizations are working to rebuild lost reefs!
