罕见的石珊瑚：潜水员视角滑过安达曼海中滤食的蜂巢珊瑚

iver POV gliding over a dense, healthy colony of Alveopora sp. coral extends its long, filter feeding polyps across a turbid Andaman Sea reef slope, swaying in the current. Alveopora is an uncommon colonial stony coral in the Indo-Pacific, found where low light favours filter feeding over photosynthesis. Each polyp carries twelve tentacles, distinguishing it from the closely related Goniopora, and extends fully only while actively feeding. 4K, wide angle medium shot, vertical frame, scuba diver POV. Ko Haa Archipelago, Andaman Sea, Krabi Province, Thailand.
