Macro View of Stiliger Sea Slug Facial Features and Cerata in Bali

A high-magnification macro underwater photograph captures an intimate, front-facing perspective of a vibrant Stiliger species sea slug crawling along the rim of a green algae frond in Bali. The tiny sacoglossan mollusk displays a vivid yellow head with blue facial markings, dark rhinophores, and a dense cluster of raised, conical cerata featuring bold dark-blue and black ringed ocelli with fine golden speckling. Positioned central to the frame, the sea slug’s detailed facial structures and front cerata stand out sharply against the vibrant green algal surface, while the edge of the leaf and soft background bokeh frame the subject. The ultra-shallow depth of field isolates the head and anterior cerata in crisp detail, softly blurring the trailing body and surroundings. Ideal for sacoglossan anatomical studies, nudibranch identification references, marine biology guides, and professional nature stock media.
