Orange Gumdrop Slug Resting on Bali Reef

An orange gumdrop slug (Goniobranchus glaniei) rests on dark coral substrate in Bali. Vibrant orange coloration stands out sharply against the volcanic reef floor. Macro perspective captures smooth body contours and soft mantle textures. Focused lighting isolates the small marine mollusk in its natural habitat. Soft bokeh blurs the surrounding ocean background. Ideal for marine biology textbooks, educational guides, and nature articles.
