泰国礁鱼环绕的巨乌贼在硬珊瑚上进食

triggerfish (Balistoides viridescens), the largest triggerfish species in the Indo-Pacific at up to 75cm, excavates hard coral on a reef wall while moon wrasse and smaller reef fish gather in its wake, feeding opportunistically on the organisms displaced by its activity. This feeding behaviour is a natural part of reef ecology: by breaking coral and turning substrate, the triggerfish exposes invertebrates that smaller species cannot access independently, creating a localised feeding chain. The surrounding reef shows encrusting algae and coralline growth across the rock face, indicating a reef in active use. 4K, wide angle, tracking scuba diver POV.
