海绵死亡珊瑚礁退化：泰国桶状海绵枯萎

barrel sponge (Xestospongia testudinaria) shows advanced tissue collapse, only a small fragment remaining of a once large specimen, evidence of sponge mortality and reef degradation in the Andaman Sea. Researchers studying similar die-offs in the Gulf of Thailand documented bleaching followed by microbial overgrowth and disintegration, with rising sea temperature a suspected stressor. A two-lined monocle bream (Scolopsis bilineata) swims past. 4K, horizontal, medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
