蘑菇水母在安达曼海开阔水域被礁石旗鱼追逐，构成海洋食物链

m jellyfish (Rhopilema hispidum) pulses through open blue water as five longfin bannerfish (Heniochus acuminatus) maintain constant pursuit, a dense school of fusiliers visible mid-water behind them. Unable to outpace its pursuers, the jellyfish alters course toward the reef structure as the bannerfish continue taking turns pecking at its oral mass. Jellyfish rely entirely on bell pulsation for propulsion rather than directional speed, making sustained evasion of active predators effectively impossible. 4K, vertical frame, wide angle, scuba diver POV.
