泰国泰坦炮弹鱼和隆头鱼捕食硬珊瑚的掠食性礁鱼行为

triggerfish (Balistoides viridescens) works a hard coral feeding site on an Andaman Sea reef as moon wrasse (Thalassoma lunare) orbit the activity, waiting to intercept dislodged material before it settles. The triggerfish is a solitary and diurnal feeder by nature, rarely sharing territory, yet its feeding excavations reliably attract a retinue of opportunistic species that have learned to read its behaviour as a foraging cue. Healthy populations of large reef predators like the titan triggerfish are considered a marker of ecosystem stability, their presence dependent on sufficient coral cover, invertebrate abundance and reef structural complexity. 4K, vertical frame, medium shot, scuba diver POV.
