Fringing Reefs
Fringing reefs or shore reefs grow parallel to the shoreline in warm, shallow water. They need abundant sunlight and a suitable hard bottom. It is also important that the water has low nutrient levels and low turbidity. Runoff or excessive sediments (like after a storm) may inhibit growth.[1]
Formation
According to Darwin's Theory, fringing reefs are formed around a volcanic island. The coastline is generally shallow and gently sloping, perfect for rapid calcium carbonate growth. As time progresses and the island submerges, a lagoon is formed between the land mass and the coral platform. This is then known as a barrierreef.
What will I see?
Boulder star and brain corals are the major species of corals found in fringing reefs.[1]
Where are they found?
Fringing reefs often form around the perimeters of islands in both the Caribbean and Indo-Pacific.[1]
