视频展示了一只水母在水中游动的场景。这只水母的身体呈黄色，形状像一个倒扣的碗，边缘有波浪状的褶皱。它的触手是黑色和黄色相间的，随着身体的摆动而轻轻飘动。背景是深绿色的海水，水中有许多细小的白色颗粒漂浮着。
The video shows a yellow jellyfish floating in green water. The jellyfish has a bell-shaped body with frilly edges and long, flowing tentacles. It moves gracefully through the water, its body undulating as it propels itself forward. The background is a solid green color, which contrasts with the bright yellow of the jellyfish, making it stand out prominently. The jellyfish appears to be in a calm, underwater environment.
A yellow jellyfish is seen against a green background, initially floating with its bell facing upwards. The jellyfish begins to contract its bell, causing it to descend slightly. As the bell contracts further, the jellyfish starts to rotate its body. The rotation continues as the jellyfish's bell fully contracts, and it moves downward. The jellyfish completes its rotation, with its bell now facing downwards and its tentacles trailing behind.
