At the Amazon river mouth, a huge 9,300 sq km coral reef system has been found below the muddy waters off the mouth of the river Amazon. As corals mostly thrive in clear, sunlit, salt water, and the waters near the mouth of the Amazon are some of the muddiest in the world, the discovery of this almost 2000 km long reef leaves scientists puzzled about the potential extent of coral reefs worldwide.
