教练鱼在安达曼海印度洋-太平洋的开阔蓝水中围绕水母游动，展示了食物链

ngfin bannerfish (Heniochus acuminatus) circle a mushroom jellyfish (Rhopilema hispidum) in open blue water, taking turns feeding on its oral mass as a school of fusiliers feeds on plankton in the surrounding water column and moon wrasse (Thalassoma lunare) forage opportunistically on displaced jellyfish tissue below. This sequence captures multiple trophic levels operating simultaneously, from planktonic filter feeding to active jellyfish predation, in a single uninterrupted food chain event. 4K, horizontal frame, wide to medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
