The video features a single jellyfish with a translucent, bell-shaped body and long, flowing tentacles. The jellyfish is seen pulsating and moving through the water, with its tentacles trailing behind. The background is a deep blue color, providing a stark contrast to the jellyfish's vibrant orange hue. The jellyfish's movements are graceful and rhythmic, and its tentacles appear to be gently swaying with the current. There are no other objects or creatures visible in the video, and the focus remains solely on the jellyfish throughout.
