持续高温导致海面温度升高，手指皮革珊瑚出现白化现象

r leather coral (Sinularia polydactyla) shows vivid pink coloration on a reef slope, consistent with bleaching stress rather than its normal cream, tan or brown tones, a sign of reef degradation. Its stubby, clustered branches give the species its finger coral name. Fluorescent pigments can appear as warm water forces the coral to expel algae, before tissue turns white or declines. Schools of snapper move through the background as the camera pushes in. 4K, wide shot to close up, vertical, scuba diver POV. Ko Haa Archipelago, Andaman Sea, Krabi Province, Thailand.
