Neon Sea Slug Silhouette Over Osaka Seagrass

Cold silver dawn light falls through the water, creating a soft, hazy backdrop over a seagrass meadow near Osaka. A sea slug rests atop the swaying green blades, its body rendered as a dark silhouette against the bright, suspended plankton. The creature's cerata stand out with faint, neon hints that catch the weak morning rays, contrasting sharply with the muted blue stillness of the early morning water. Fine particles drift in the distance, softening the view of the underwater landscape. The grass blades bend slightly under the water's gentle movement, their tips catching the light while the slug remains motionless in the center of the frame. One cerata edge glows faintly where it meets the silver water.
