Coral Reefs: Underwater Ecosystems

Coral reefs are intricate underwater ecosystems formed by colonies of tiny coral polyps that build calcium carbonate structures over millennia. These vibrant ecosystems support a diverse array of marine life, including fish, mollusks, and sea turtles, making them one of the most biodiverse regions on the planet.

Coral reefs are often referred to as the 'rainforests of the sea' due to their rich biological diversity. However, they face significant threats from climate change, pollution, and overfishing, highlighting the need for conservation efforts to protect these vital ecosystems.
