Living deep‑water coral reef discovered off Benin coast

A deep‑water coral reef off the coast of Benin, long thought to be extinct, has been confirmed alive and thriving. Initial surveys conducted in the 1960s, which aimed to locate promising fishing grounds, identified a possible reef structure but concluded it must be dead based on the limited technology of the era. A recent expedition employing a modern sonar survey and the Deep Sea Camera System supplied by the National Geographic Exploration Technology Lab revisited the site and captured high‑resolution imagery that revealed a vibrant, healthy coral community.

The discovery underscores the value of contemporary deep‑sea exploration tools in reassessing historical assumptions about marine ecosystems. Researchers noted robust coral growth and a diverse assemblage of associated fauna, suggesting the reef has persisted despite decades of presumed decline. The findings will inform future conservation strategies and may prompt renewed investigations of other overlooked deep‑water habitats in the region.
