Search the grass beds for turtles and stingrays from your personal viewing window. If you are really lucky, you may see a dolphin or two swim by. The Nautilus diver conducts a fish feeding in the water that brings the fish close to your window. Begin or end your Nautilus adventure with a self-guided exploration of Coral World Ocean Park.
