安达曼海礁石上的红藻正在吞噬扇形海扇

roalgae (Rhodophyta spp.) smothers the upper branches of a gorgonian sea fan in a visible sign of algal bloom, the camera orbiting to reveal the full extent of overgrowth. At 30 degrees Celsius, the sea surface temperature recorded here reflects conditions driving algal proliferation across Indo-Pacific reefs. Without intervention, this level of algal coverage will eventually kill the host coral. 4K, horizontal, medium shot, orbiting camera move, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
