A medium shot, low-angle underwater scene featuring a massive megalodon swimming majestically through the deep ocean. The prehistoric shark is the central focus, its colossal body detailed with rough, sandpaper-like skin textures, jagged gills, and a powerful caudal fin propelling it forward. Its mouth is slightly open, revealing rows of immense, serrated triangular teeth and a dark, cavernous throat. The background consists of a dark, hazy aquatic void with shafts of ethereal sunlight filtering down from the surface, illuminating floating marine snow and tiny bubbles. The visual style is a high-quality anime illustration with a deep blue and turquoise color palette, featuring cinematic lighting, volumetric rays, and a sense of overwhelming scale and primordial power.
