Seal Through Blue Hole in Sardinia Twilight

Cool blue twilight water fills the frame as a seal swims through a circular opening cut by surface ripples. Kelp fronds drift in the foreground, their dark green blades swaying beside a rugged rocky shelf. A soft plankton haze blurs the distance, creating layers of depth that recede into the dimming water. Above the surface, faint city lights begin to glow, reflecting as scattered points of warmth against the dominant cool tones. The seal's sleek form moves cleanly through the blue hole, its smooth skin catching the fading ambient light. Small bubbles cling near the rocky edge, marking the water's movement. The scene ends with the dark silhouette of the seal turning toward the deeper blue void.
