安达曼海海底珊瑚礁壁上，红色海鞭海扇在水中摇曳

ea whip (Ellisella ceratophyta) sways in the tidal current on a shallow underwater reef wall in the Andaman Sea, its open feeding polyps central to reef filter feeding activity. As a gorgonian species, the sea whip depends on consistent water movement to deliver suspended plankton across its polyps, while the current also flushes sediment that would otherwise smother its feeding surfaces. A tranquil scene typical of the wider coral reef ecosystem. 4K, wide angle, vertical, wide shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
