视频中展示了一只水母在深蓝色的海洋中游动。水母的身体呈现出橙色和棕色的条纹，触须细长且透明，随着水流轻轻摆动。背景是清澈的蓝色海水，水中有一些微小的颗粒物漂浮着，营造出一种宁静而神秘的海底氛围。
The video features a single jellyfish floating gracefully in deep blue water. The jellyfish has a translucent, bell-shaped body with long, flowing tentacles that move rhythmically as it swims. The background is a serene, uniform blue, creating a calm and mesmerizing underwater scene. Small particles can be seen drifting in the water, adding to the tranquil atmosphere.
A jellyfish with a brown and orange bell and long, trailing tentacles is seen against a deep blue background. The jellyfish begins to contract its bell, causing its tentacles to spread out and move downward. As the bell contracts further, the tentacles continue to extend and sway gently. The jellyfish then starts to move backward, maintaining its contracted bell and extended tentacles.
