Nutrient-rich currents that well up towards the surface create a plankton bloom that attracts ocean giants. Whale sharks are the largest fish on Earth growing to over 15 metres long. Trawling the oceans with mouths agape, their sieve-like gills sift out the plankton and small fish on which they feed. Djibouti is famous for this annual gathering of whale sharks, which migrate here each winter from far across the Indian Ocean to take advantage of the Great Rift’s fertile waters.
