宁静的海底珊瑚礁景观：红扇形海扇珊瑚在蓝色的水中过滤喂食

orgonian sea fan coral sways gently in the tidal current on a deep reef wall, its polyps fully extended to filter feed against an open expanse of deep blue water offering generous copy space. The coral's fine branching structure and vivid colour make it one of the more photogenic indicators of a healthy, current swept reef environment, well suited to calm nature backdrop use. 4K, wide angle, vertical medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
