The video shows a group of people swimming in the ocean, with a large manta ray swimming nearby. The water is clear and blue, and the ray is seen gliding through the water with its wings spread wide. The people are wearing swimsuits and appear to be enjoying the experience of being in the water with the ray. The ray's movements are graceful and slow, and it seems to be undisturbed by the presence of the swimmers. The video captures the beauty of the underwater world and the majesty of the manta ray.
