The video captures a close-up view of a jellyfish swimming underwater. The jellyfish is illuminated by sunlight filtering through the water, creating a radiant and ethereal effect. Its translucent body and flowing tentacles are clearly visible as it moves gracefully through the blue water. The scene is serene and mesmerizing, highlighting the delicate beauty of this marine creature.
A jellyfish is seen floating in the water, with its translucent body and dark fringes clearly visible. The jellyfish begins to contract its body, causing its fringes to curl and its shape to become more compact. As it continues to contract, the light within its body becomes more pronounced, illuminating the surrounding water. The jellyfish's contraction progresses further, with its body becoming more rounded and its fringes trailing behind. The contraction reaches its peak, with the jellyfish's body almost fully contracted and its fringes spread out in a delicate, wispy pattern.
