The video shows a black and white image of a jellyfish swimming in the water. The jellyfish has a long, thin body and is moving slowly through the water. The video is shot from a side angle, allowing us to see the jellyfish's tentacles trailing behind it. The water is clear, and we can see small particles floating around the jellyfish. The video is shot in slow motion, making the jellyfish's movements appear graceful and fluid.
