The video features a single jellyfish, with a translucent body and long, thin tentacles, swimming in the water. The jellyfish's body is bell-shaped and appears to be made of a gelatinous material. The tentacles are long and thin, with small, round, and bulbous ends. The jellyfish moves slowly and gracefully through the water, with its tentacles trailing behind it. The background is a blurred greenish-blue color, suggesting that the video was taken underwater. There are no other visible creatures or objects in the video.
