Underwater Lace of Red Algae

A delicate macro photograph of a red marine algae frond floating naturally just below clear seawater. Branching translucent crimson membranes fan across the frame like fine lace, anchored to a tiny unseen support outside the crop so the stem direction is coherent. Sunlit ripples cast slow pale caustics across the living tissue; a few minuscule oxygen bubbles sit along one branch. Deep blue-green water background, elegant negative space at top left, rich translucent edges and subtle veins, documentary botanical realism, not fabric, no fish or text.
