两条长鳍旗鱼在珊瑚礁上围绕着一只正在白化的巨型桶状海绵游动

gfin bannerfish (Heniochus acuminatus) navigate around a giant barrel sponge (Xestospongia sp.) showing visible bleaching stress on a degraded Indo-Pacific coral reef, the sponge's normally deep brownish-red surface faded to pale pink, a recognised stress response to rising sea temperatures. Barrel sponges are among the ocean's longest-lived invertebrates, with some colonies exceeding 2,000 years old, making each bleaching event a measurable loss of ancient reef structure. The surrounding substrate shows algae overgrowth and sediment accumulation, both indicators of chronic reef stress. The bannerfish continue to shelter and feed among the weakened coral framework. 4K wide angle, scuba diver POV. Location is Andaman sea, Thailand.
