Check out this incredible footage of a woman swimming with Manta Rays. Dylan de Haas, had been driving up and down the beach in Ningaloo, Western Australia, for five days searching for the magical creatures. However, one morning, the manta rays, which are the largest rays in the world, appeared and they were close enough to shore to swim with. Sarah De Haas, Dylan’s wife, managed to get up close and personal with the rays and enjoyed their company for the best part of two hours.
