Dubai Aquarium is one of the largest aquariums in the world and has thousands of aquatic animals including sharks and rays. A 270-degree acrylic walk-through tunnel lets visitors enjoy close-encounter experiences with some of the most fascinating underwater animals on the planet. A special 'lunar-cyclic' lighting system changes the ambiance of the tank depending on the time of day. Underwater Zoo is located above the aquarium, and provides an interactive approach to educating children and visitors on the ecology and sustainability of marine life.
