The video features several jellyfish swimming in the water. The jellyfish are translucent and have a bell-shaped body with tentacles hanging from the edges. They move slowly and gracefully through the water, with their tentacles trailing behind them. The water is a deep blue color, and the jellyfish are illuminated from above, making them appear to glow. There are no other objects or creatures visible in the video, and the focus is solely on the jellyfish.
