条纹拟刺尾鱼在安达曼海退化珊瑚礁上游弋，珊瑚白化

hed moon coral (Dipsastraea spp.) sits pale and drained of colour at the centre of a wide degraded reef seascape in the Andaman Sea, its surface having transitioned from healthy dark brown through pale beige toward full white as thermal stress forced the expulsion of its symbiotic zooxanthellae algae. A striped surgeonfish (Acanthurus lineatus) moves across the foreground, still actively using a reef showing significant signs of coral reef decline and biodiversity loss. Sponge and coral rubble fill the surrounding substrate. 4K, wide angle tracking shot, scuba diver POV. Ko Haa National Marine Park, Krabi Province, Thailand.
