This 23-second 4K underwater clip captures a large lion’s mane jellyfish swimming gracefully through the open water column. The jellyfish pulses slowly, its long tentacles trailing behind as it drifts against a clear blue-green ocean backdrop. Filmed with a 16–35mm wide-angle lens, the composition allows the jellyfish’s size and texture to stand out in open space, while subtle background gradients create a serene, cinematic feel. The natural light and extended duration make this clip highly adaptable for marine documentaries, jellyfish species profiles, or artistic underwater features. Both graded and ungraded versions are included with your purchase.
