A strange creature in the shape of a sphere with a shell, inside of which one can see rotating rings and slowly moving fins. It shimmers with blue and violet light, and its \"gills\" shimmer with bright flashes of green. Close-ups show small glowing tentacles with which the creature catches microscopic planktonic inhabitants. All around are the dark waters of the ocean, illuminated only by this mysterious creature. The camera slowly rotates around him, capturing his bioluminescent show.
