海洋生物侵蚀：火烈鸟鹦嘴鱼鱼群正在啃食鹿角脑珊瑚

coral head (Platygyra sp.) sits alongside a shallow Andaman Sea reef where a swarming school of Ember Parrotfish (Scarus rubroviolaceus) is actively grazing. One side of the limestone structure shows distinct scoured marking from where the fish have scraped away competitive turf algae and dead surface matter. The school continuously feeds and excretes fine coral sand in real time, offering a clear close-up record of active marine bioerosion mid-process. This essential herbivorous activity limits algae overgrowth, ensuring the surrounding coral community stays healthy. Shot on a wide-angle lens with a vertical close-up framing from a scuba diver POV. Andaman Sea, Krabi Province, Thailand.
