珊瑚礁生物多样性丧失：安达曼海退化珊瑚礁上成群的蝙蝠鱼

batfish (Platax teira) school in open blue water above a degraded Andaman Sea reef, their disc-shaped bodies distinct against the blue water column, the broken substrate below conveying the scale of reef biodiversity loss across this Indo-Pacific reef section. Batfish often persist on reef systems under pressure where structural complexity has been reduced by bleaching events and coral degradation, making them a useful indicator species. 4K, vertical, wide angle, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
