Coral reefs are like underwater cities where colorful animals live and work together to build a strong home.
Coral is like tiny, hard-working builders who make reefs, big, pretty structures that grow over time. Each coral is made of small creatures called polyps, which are like little sea bugs with soft bodies and tough skin.
How Coral Reefs Are Built
Imagine you're stacking blocks to build a tower. That's what corals do, they add one piece at a time. They use calcium carbonate, a kind of special sand, to make their hard shells. Over many years, these tiny buildings grow into big underwater neighborhoods.
What Lives in Coral Reefs
Coral reefs are not just for corals, they're like busy cities! Fish, sea turtles, crabs, and even little anemones (which look like wildflowers) live there too. They all help each other out: some fish hide in the coral, while others eat the algae that grow on it.
Coral reefs are strong but need care, just like a city needs good neighbors to stay happy and healthy.
