Blue Shark Silhouette Through Kelp Doorway

Cool evening blue light falls through a dense forest of kelp fronds near Havana, illuminating the dark silhouette of a blue shark swimming with a small pilot fish. A vertical wall of dark stone rises from the seabed, but a rectangular doorway opens directly into the open ocean beyond. The impossible opening frames the shark against the luminous water, where slow-moving surface ripples distort the light. Shallow depth of field blurs the foreground kelp into soft, swaying shapes while the shark remains sharp. Shadows stretch across the sandy floor, and the edge of the stone wall meets the clear water in a seamless, impossible transition.
