海洋保护珊瑚礁生态：泰国无共生藻的海扇

nian sea fan (species unconfirmed) dominates this medium shot on an Indo-Pacific reef, its branching colony oriented perpendicular to the prevailing current to maximise particle capture. Azooxanthellate gorgonians feed entirely by filtering zooplankton and organic matter through their polyps, requiring no sunlight or symbiotic algae. Scattered reef fish and mixed coral substrate are visible behind. Copy space in blue water above. 4K, horizontal, wide angle, medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
