Amazon Reef, Coral and sponge reef system off Maranhão, Brazil
The Amazon Reef extends over 1,000 kilometers along the Brazilian coast, reaching depths between 30 to 120 meters in the Atlantic Ocean waters.
Scientists first detected evidence of the reef structure near the Amazon River delta in the 1950s through sponge collections and fish observations.
Local fishing communities in northern Brazil maintain traditional fishing practices around the reef, which supports populations of fish and marine life.
The reef system receives limited sunlight due to the Amazon River sediment plume, affecting marine life distribution and research capabilities.
The reef formation contains 61 different sponge species and 73 types of fish, surviving despite massive sediment deposits from the Amazon River.
