泰国海域，黄缘龙占鱼在印度-太平洋珊瑚礁上方游弋

wmargin triggerfish (Pseudobalistes flavimarginatus) hovers in open water above a degraded reef as scuba divers' exhalation bubbles rise from below in a natural Indo-Pacific reef wildlife encounter. This species feeds on hard-shelled invertebrates including sea urchins, regulating urchin populations whose unchecked growth can accelerate bioerosion on thermally stressed and reef-degraded systems. 4K, horizontal, medium, wide angle, scuba diver POV.
