The video shows a close-up view of a jellyfish, likely a moon jellyfish (Aurelia aurita), with its translucent blue body and delicate tentacles. The jellyfish is illuminated, highlighting its intricate internal structures and the flowing motion of its tentacles. The background is dark, which enhances the glowing appearance of the jellyfish, making it stand out vividly. The jellyfish appears to be gently pulsating as it moves through the water.
A jellyfish with a translucent, blue-tinged bell and long, trailing tentacles is seen against a dark background. The jellyfish's bell contracts and expands rhythmically, propelling it forward. The tentacles and oral arms, which are frilly and delicate, move gently with the contraction and expansion of the bell. The jellyfish's movement is smooth and continuous, showcasing the fluid dynamics of its body.
