of brown algae, Padina pavonica, grows attached to coral rubble on a reef in the Andaman Sea, its fan shaped blade curling into the tight concentric scroll that gives this reef algae its common name, peacock's tail. Pale bands across the surface form where calcium carbonate accumulates within the tissue, distinct from coral bleaching. Padina pavonica is common on tropical reef habitat, growing on rock or coral rubble rather than live coral. 4K, wide angle, vertical medium shot, scuba diver POV.
