Whale Shark in Sunbeam

Create a realistic wide-angle underwater wildlife photograph, featuring a {argument name="main animal" default="whale shark"} Swimming diagonally across the deep blue waters. The perspective is slightly higher and in front of it, allowing its broad, spotted head to dominate the lower left foreground, while its body and tail extend to the lower right. The whale shark's grey-blue skin should have precise white dots and stripes, with visible gill slits, pectoral fins, and dorsal fins, exhibiting an elegant, slow swimming posture. A silhouette of a diver (with fins and a tank) is visible in the upper center of the image as a proportional reference. A beam of warm golden sunlight shines diagonally from the upper right to the lower left, illuminating suspended particles, bubbles, and plankton in the water. Using natural light and a color palette ranging from deep turquoise to navy blue, the film creates a soft underwater mist, realistic bokeh, cinematic depth of field, and subtle motion blur from floating particles, resulting in an immersive documentary feel. No text, no borders, and no artificial aquarium background.
