Coral Reefs: Underwater Ecosystems

Coral reefs are vibrant underwater ecosystems composed of coral polyps that build elaborate structures in warm, shallow ocean waters. These reefs provide essential habitats for a wide variety of marine life, including colorful fish, sea turtles, and crustaceans.

Coral reefs are often referred to as the 'rainforests of the sea' due to their rich biodiversity. However, coral reefs face threats from climate change, pollution, and overfishing, making their conservation critical for ocean health.
