Coral Reef

A coral reef is a vibrant underwater habitat formed by colonies of tiny marine animals called corals, which have skeletons that build up over time. These reefs are often called "rainforests of the sea" because they support a vast diversity of life, including fish, mollusks, and sea plants. Reefs thrive in warm, shallow ocean waters and are vital for coastal protection, tourism, and marine ecosystems. They also face threats from climate change, pollution, and overfishing, making their conservation essential for environmental health.
