The video shows a close-up of a jellyfish swimming in the water. The jellyfish has a translucent body with long, flowing tentacles that move gently in the water. The jellyfish's body pulsates rhythmically, propelling it through the water. The background is blurred, but it appears to be an underwater environment with some rocks and plants visible. The lighting is natural, suggesting that the video was taken during the day. There are no other creatures or objects in the frame, making the jellyfish the sole focus of the video.
