两条鹦嘴鱼在安达曼海退化的裸露岩石礁上游动

rotfish (Cetoscarus ocellatus) patrol above a bare rocky seabed, the encrusting coral that once covered these boulders reduced to algae-covered skeleton. Parrotfish are critical reef herbivores whose algae grazing clears substrate for coral settlement after bleaching. On degraded reefs with low coral cover, however, their incidental corallivory can introduce bacterial transmission risk that reduces resilience in surviving colonies. 4K, vertical, wide angle, tracking shot, scuba diver POV.
