Realistic wide-angle underwater wildlife photograph of a [whale shark] swimming gracefully and slowly diagonally through deep blue ocean water. Viewed from slightly above and in front, its broad spotted head dominates the lower-left foreground while its tapering body and tail recede toward the lower-right. Accurate white polka-dot and stripe markings across gray-blue skin, visible gill slits, pectoral fins, and dorsal fins. A single small scuba diver silhouette with fins and tank is visible high above near the upper center for scale. A warm golden sunbeam cuts diagonally from the upper right down toward the lower left, illuminating drifting plankton, suspended particles, and bubbles with a realistic caustic glow. Deep turquoise-to-navy color grading, soft underwater haze, cinematic depth, subtle motion blur on floating particles, immersive documentary feel. No text, no borders, no artificial aquarium setting.
