A coral reef thought to be dead for over 60 years has been discovered off the coast of Benin, alive and in apparent good health. In the 1960s, surveys were conducted to identify productive fishing areas, and what appeared to be a deep-water coral reef was detected. At the time, scientists believed the reef was likely dead. Recently, researchers revisited the location using modern technology, including sonar and the Deep Sea Camera System from the National Geographic Exploration Technology Lab, to investigate further. Using sonar, the team scanned 11.5 kilometers of the seafloor and identified two areas with signals resembling coral reefs. They then deployed an underwater drone and the camera system, which functions like underwater trail cameras, to examine these locations more closely. The footage revealed a thriving coral community, with eight different types of coral and eight species of fish that use the reef for shelter and feeding. Among the fish species observed were golden African snappers, blackbar soldierfish, and various types of butterflyfish and damselfish. The reef does not form a single, continuous wall of coral but instead consists of separate coral patches growing on rocky sections of the seabed where conditions are favorable. This discovery raises the possibility that other coral reefs may exist in the coastal waters of West Africa that have yet to be documented. Scientists believe more surveys could uncover additional reefs nearby. Historical reports suggested the possibility of a continuous reef barrier extending about 40 kilometers parallel to the coast, but researchers emphasize that this is only an initial assessment. To confirm the findings, researchers will need to collect physical samples of the corals and conduct further studies. They also aim to determine whether the corals observed in the 1960s were indeed dead and have since recovered, or if the original survey misinterpreted the findings. The site is believed to be the first confirmed record of a living mesophotic coral ecosystem on the Gulf of Guinea continental shelf. These ecosystems are found in deeper, darker waters than typical shallow reefs and often appear as scattered or patchy coral communities rather than forming a continuous structure.
