水下珊瑚礁食物链：泰国多种生物以硬珊瑚伤痕为食

ng scar left by titan triggerfish predation on hard coral now draws moon wrasse (Thalassoma lunare), moorish idol (Zanclus cornutus) and checkerboard wrasse (Halichoeres hortulanus) into frame, each exploiting bio-erosion debris left behind on the exposed calcium carbonate exoskeleton. The mix of species feeding at a single site shows how one predation event can support several reef fish at once. This close framing captures the shared food chain value of a single coral feeding scar. 4K, wide angle, horizontal close up, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
