视频展示了一只黄色的水母在水中游动的画面，这只水母的身体呈圆形，颜色为鲜艳的黄色，边缘有波浪状的褶皱，它的触手是黑色的，上面有一些黄色的斑点，它在水中缓缓地游动着，身体不断地收缩和舒张，背景是一片深绿色的海水，海水中有许多细小的气泡。
The video shows a yellow jellyfish floating in green water. The jellyfish has a bell-shaped body with a smooth, translucent surface and several tentacles hanging below. It moves gracefully through the water, its body pulsating gently as it propels itself forward. The background is a uniform green, suggesting an underwater environment. The jellyfish's movements are slow and fluid, creating a serene and mesmerizing scene.
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 downward. The rotation continues as the jellyfish's bell fully contracts, and it moves further downward. The jellyfish completes its rotation, now almost upside down, with its bell facing downward and its tentacles trailing behind.
