珊瑚白化：鱼群在安达曼海浅礁上方觅食

school of goldband fusilier (Pterocaesio chrysozona) and lyretail anthias (Pseudanthias squamipinnis) mass above a Porites lutea coral head showing coral bleaching and reef degradation, red algae colonising bare skeleton. Morning sunbeams light a reef still visibly productive despite the stress. Porites are key indicators of reef health, and this fish biomass hints at resilience, though repeated bleaching could overwhelm it. 4K, wide angle, vertical wide shot, scuba diver POV.
