泰国印度洋-太平洋珊瑚礁上，草食性鹦嘴鱼的喂食行为，拍摄于白化珊瑚礁

tfish (Cetoscarus ocellatus) grazes a degraded reef among bleached mushroom corals, its fused beak teeth scraping algae in feeding behaviour central to Indo-Pacific reef health. Parrotfish grazing keeps algal colonisation in check after bleaching events, maintaining open substrate that coral larvae need to settle. Reefs with healthy parrotfish populations recover from disturbance faster than those where the species has been depleted. 4K, horizontal, wide angle, tracking, scuba diver POV.
