A team of Beninese scientists has rediscovered a thriving coral reef off the coast of Benin, West Africa, which was previously thought to be dead. The reef, located 175 feet below the surface, is home to at least eight coral types and eight fish species. The discovery was made possible by a $20,000 National Geographic Explorers grant and the help of local fishermen. The team hopes this will spark a wave of similar discoveries in the waters off West Africa.
