A medium shot from a side profile shows a slender, non-human dragon swimming gracefully through the deep ocean. The creature possesses a long, serpentine body with a cream-colored head that smoothly transitions into a vibrant blue gradient toward its tail. Its scales shimmer with a vivid iridescent rainbow luster, reflecting the light. Bright red whiskers and antennae extend from its head, and delicate fins are positioned at various points along its body, gently undulating as it glides. The surrounding environment is a deep blue underwater void, filled with tiny floating bubbles and shimmering caustic light patterns filtering down from the surface. The atmosphere is serene and ethereal, characterized by a cool color palette and a sense of weightless tranquility.
