Surreal Floating Island Split Above And Below Waterline

A surreal floating island ecosystem is depicted, split horizontally by the waterline. The upper half is a vibrant, lush terrestrial environment filled with dense green foliage, mosses, ferns, and various trees, bathed in soft, diffused sunlight. Small fish are visible swimming amongst the underwater flora. The lower half is an underwater scene teeming with diverse aquatic life, including a central, large shark with dark spots on a lighter body, surrounded by several smaller, striped and patterned fish and colorful coral formations. The island is positioned centrally within the frame, with a slight tilt downwards, creating a dramatic perspective. The overall lighting is soft and ethereal, with a gentle glow emanating from the upper right, illuminating the scene and casting subtle reflections. The atmosphere is one of vibrant, magical naturalism, rendered with photorealistic detail.
