泰坦炮弹鱼从珊瑚礁洞中探出头，然后又缩了回去 动物行为

triggerfish (Balistoides viridescens) emerges from a coral reef crevice to resume coral predation on hard coral already marked by bioerosion, then withdraws fully back inside for concealment. Schools of goldband fusilier and other tropical reef fish swim above, illustrating the reef fish biodiversity this Andaman Sea structure supports. Titan triggerfish shelter in crevices, wedging themselves in using a locking dorsal spine. 4K, wide angle, horizontal medium shot, side view, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
