Graceful Black and White Sea Turtle Underwater

Hyper-detailed black and white underwater scene of a sea turtle gracefully swimming. Side/three-quarter view from slightly below the turtle, showcasing a meticulously textured carapace with intricate scute patterns and micro-scratches, and lifelike wrinkled skin on the head and flippers. Soft, diffuse light beams from the surface slice through clear water, creating dramatic chiaroscuro - bright highlights on the shell rims and the edges of each flipper, deep blacks in the shadowed recesses, and midtones across the creature's contours. Bubbles drift upward and tiny particles float, adding depth. The background fades into a gentle blur with faint silhouettes of seaweed and distant corals to establish depth, but remains unobtrusive to keep the focus on the turtle. The image should feel like a high-resolution monochrome photograph or graphite/charcoal drawing, with crisp linework on the turtle's outline and subtle shading that conveys texture, volume, and motion, conveying graceful, serene motion as the sea turtle glides through the water.
