Dolphin in a Mountain Cave - 3D Render

Ultra-detailed 3D render of a sleek dolphin gliding through a subterranean mountain cave. Inside a narrow, glittering river, the dolphin's wet skin reflects damp cave walls. Bioluminescent algae line the stalactites and crevices, casting a cool blue-green glow with warm amber highlights from hidden cave lamps. Realistic lighting with caustics on wet rock, misty air, and rippling water surface. Cinematic wide-angle shot from a slightly low underwater perspective, shallow depth of field, high-detail skin textures and micro-scales. Textures include rugged rock, wet moss, shimmering water, and translucent cave minerals. Color palette dominated by cool blues and greens with occasional orange accents. Rendered with physically-based shading, ray tracing, and high polygon count for photorealism.
