垂直水下镜头：清晰蓝水中红海扇珊瑚的分支

red gorgonian sea fan coral (Subergorgia spp.) fills the vertical frame, its branching skeleton a marker of reef biodiversity and marine ecosystem structure in the Andaman Sea. This filter-feeding coral relies on steady currents to capture plankton, and its presence signals a reef ecosystem still capable of supporting complex marine life. Sunbeams penetrate the water column behind it. 4K, vertical frame, low angle, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
