The video shows a scuba diver in a yellow and black wetsuit swimming in the ocean. The diver is accompanied by a large manta ray, which is swimming gracefully next to them. The water is a deep blue color, and there are several small fish swimming around the diver and the manta ray. The manta ray has a distinctive shape with a long, flat body and large pectoral fins. The diver appears to be in awe of the manta ray's size and beauty.
