Long-lost coral reefs rediscovered off the coast of Africa

Around 60 years ago, scientists believed a coral reef off Benin’s coast in West Africa was dead. However, recent research led by Gérard Zinzindohoué has revealed that this reef is actually a thriving deep-water community. Initially detected in the 1960s, the reef was overlooked due to its depth and the limited technology of the time. Using advanced tools like high-resolution sonar and underwater drones, the team discovered a living coral ecosystem in the ocean’s “twilight zone,” known as a mesophotic reef. Unlike typical shallow reefs, these reefs exist in dimly lit waters and consist of scattered coral patches. This discovery, published in Frontiers in Marine Science, is the first confirmed living mesophotic coral ecosystem on the Gulf of Guinea’s continental shelf. Future research will explore the reef’s history and extent, as ocean science in West Africa is still developing. QUESTION: How might the rediscovery of this coral reef influence future marine research and conservation efforts in West Africa?
