Coral reef rediscovery off Benin coast

Overview

Researchers have rediscovered a living mesophotic coral reef off the coast of Benin, an ecosystem previously presumed dead for approximately 60 years. The area was formerly categorized as a sterile underwater graveyard following 1960s fishing surveys that utilized primitive dredging and sonar technology.

A scientific expedition using modern technology, including side-scan sonar and underwater drones equipped with deep-sea camera systems, successfully mapped the seabed and verified the presence of a vibrant habitat. Located at depths of approximately 50 to 54 meters in the Gulf of Guinea, the reef hosts multiple species, including eight distinct coral types and various fish species such as Guinean angelfish and golden African snappers. The discovery highlights significant gaps in West African marine data and offers new information for regional conservation efforts.
