安达曼海，广阔的珊瑚礁上，一群黄鲷鱼在竖构图的远景镜头中游弋

snapper (Lutjanus lutjanus) school above an Andaman Sea reef, their mass presence across the water column reflecting the marine biodiversity and reef ecosystem health that defines productive Indo-Pacific dive destinations. The reef floor below shows encrusting substrate and rubble, with a young barrel sponge visible among the reef structure, an early sign of new growth on this section of reef. Barrel sponges are among the longest-living reef organisms in the Indo-Pacific, with large specimens estimated to be several hundred years old. 4K, vertical frame, wide establishing shot, scuba diver POV.
