长鳍旗鱼在安达曼海硬珊瑚尖峰上方捕食水母

oom jellyfish (Rhopilema hispidum) pulses urgently above a Porites coral pinnacle as longfin bannerfish (Heniochus acuminatus) press in from multiple angles, the opening close shot resolving to a medium frame as the jellyfish attempts to gain open water. Porites corals are among the slowest-growing and most structurally critical on Indo-Pacific reefs, their boulder formations providing the elevated topography that concentrates predator and prey interactions like the one unfolding in this clip. 4K, horizontal frame, close to medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
