Benin Reef Rediscovered: A 60-Year Marine Mystery Solved
21 Jul
Summary
- A healthy coral reef was discovered off Benin's coast after 60 years.
- The reef hosts at least eight coral types and eight fish species.
- Scientists hope the reef will become a protected marine area.
Sixty years after surveyors first noted its potential, a thriving coral reef ecosystem has been rediscovered off the coast of Benin. Initial evidence surfaced in the 1960s, but the find was largely overlooked until a team led by Gérard Zinzindohoué embarked on a mission to locate it.
Securing a National Geographic Explorers grant in January 2025, the project faced logistical hurdles, including acquiring specialized sonar equipment and relying on local fishermen to reach the site 14 miles offshore. After months of challenging fieldwork, the team successfully identified two strong sonar echoes.
Further investigation using a deep-sea camera system revealed a mesophotic coral ecosystem (MCE) at over 175 feet below the surface. This vibrant site hosts at least eight coral types and eight fish species, including African snappers and Monrovia doctorfish.
Scientists believe this undisturbed ecosystem could provide valuable insights into past climate conditions and is crucial for marine biodiversity. Conservation efforts are already underway, with proposals to designate the area as a marine protected area and an Important Shark and Ray Area.
