珊瑚礁生物侵蚀：鹦嘴鱼的疯狂觅食给硬珊瑚礁留下疤痕

school of Ember Parrotfish (Scarus rubroviolaceus), aka Redlip Parrotfish or Bicolour Parrotfish, feed aggressively on hard coral in a bio-erosion feeding frenzy across a shallow Andaman Sea reef. Fine white scrape marks scar the porites coral surface where fused beak teeth chip away limestone to reach algae hidden inside. The damage looks destructive, but this coral reef ecology process clears space for new coral to grow. 4K, wide angle, horizontal establishing shot, forward movement, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
