视频中展示了一只水母在深蓝色的背景中游动。水母的身体呈现出半透明的紫色，触须细长且柔软，随着水流轻轻摆动。它的伞状身体在水中缓缓收缩和扩张，显示出其独特的游泳方式。整个画面给人一种宁静而神秘的感觉，仿佛置身于深海之中。
The video shows a jellyfish floating in deep blue water. The jellyfish has a translucent, bell-shaped body with long, flowing tentacles extending downward. It moves gracefully through the water, its body pulsating gently as it propels itself forward. The background is a dark blue, creating a serene and mysterious underwater atmosphere. The jellyfish's delicate structure and ethereal appearance are highlighted by the lighting, giving it a glowing effect.
A jellyfish is seen floating in a deep blue underwater environment. The jellyfish begins to contract its bell, causing its tentacles to start curling inward. As the contraction continues, the bell becomes more rounded, and the tentacles are pulled closer to the body. The jellyfish's bell reaches its peak contraction, and the tentacles are fully curled inward. The jellyfish starts to relax, and the bell begins to expand slightly, with the tentacles extending outward again. The jellyfish continues to relax, and its bell returns to a more open state, with the tentacles extending further.
