Barrier reef ecology

Barrier reefs are large coral structures located parallel to coastlines, separated by deeper lagoons. They provide crucial habitats for a diverse range of marine life, including fish, crustaceans, and sea turtles. The ecology of barrier reefs is complex, involving symbiotic relationships, such as coral and algae living together. Corals are essential builders of the reef structure and protect coastlines from erosion. These ecosystems also support vulnerable species and are vital for fishing and tourism. However, barrier reefs face threats from climate change, pollution, and overfishing, making their conservation critical for marine biodiversity and coastal protection.
