Underwater Zebra: Photorealistic Ocean Scene

Photorealistic zebra swimming underwater in a sunlit tropical ocean. The zebra's black-and-white stripes are sharply detailed against blue-green water. Sunbeams pierce the surface, casting dappled caustics on a coral reef and sandy ocean floor. The zebra's mane and tail flow with the current; bubbles rise from its nostrils. Surrounding scenery includes colorful coral, swaying sea grasses, and a school of tiny tropical fish, with realistic water texture, light refraction, and natural color grading.
