The video shows a large manta ray swimming in the ocean. The manta ray has a black and white body with a long tail and a wide, flat body. It is swimming gracefully through the water, with its wings moving slowly. The ocean is a deep blue color, and the light from above the water creates a beautiful pattern on the manta ray's body. There are small fish swimming around the manta ray, but they do not interact with it. The video is shot from a distance, allowing for a full view of the manta ray's size and movements.
