The Gulf of Aqaba is famous for its marine wildlife. It is the north-eastern arm of the Red Sea, measuring a length of 180km and expanding to a width of 25km, with a shoreline shared by Egypt, Saudi Arabia, Israel, and Jordan. The Gulf of Aqaba has the world’s northernmost coral reef ecosystem. An average water temperature of °23 Celsius, the absence of stormy weather, and mild water currents have created a hospitable environment for the growth of corals. Favorable salinity levels are perfect for the myriads of other marine life-forms. As a result, it is home to 110 species of soft corals and 120 species of hard corals. The reefs that fringe the Gulf host over 1,000 species of fish, corals, crustaceans, and mammals living in its waters. Nocturnal animals such as the crab, shrimp, and lobster appear in search of food in the dark hours of the night. Seasonal visitors to the Gulf of Aqaba include sea turtles, dolphins, sea cows, and harmless whale sharks.
