The video shows a jellyfish swimming in the ocean. The jellyfish has a clear, gelatinous body with a bell-shaped top and trailing tentacles. The tentacles are dotted with small, yellow-orange spots. The jellyfish moves slowly and gracefully through the water, contracting and relaxing its bell to propel itself forward. The surrounding water is a deep blue color, and there are no other visible creatures or objects in the frame. The jellyfish appears to be the only focus of the video.
