早晨阳光下的礁墙上海扇珊瑚

nian sea fan coral (order Alcyonacea) extends across a shallow reef wall in the Andaman Sea, its white feeding polyps open to filter plankton from the passing current beneath shafts of morning sunlight. Gorgonian sea fans anchor to hard reef substrate and orient themselves side on to prevailing currents, maximising exposure for suspension feeding across the coral reef ecosystem. Tranquil low angle composition. 4K, wide angle, vertical, low angle, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
