安达曼礁石上的健康红海鞭珊瑚与月亮神仙鱼

nt red sea whip coral (Ellisella spp. or Junceella spp.) extends from an Andaman Sea reef wall into the current, its polyps fully deployed to filter nutrients from the water column in a posture that reflects ideal reef conditions at this location. A moon wrasse (Thalassoma lunare) passes in the foreground, its electric green and blue colouration contrasting sharply against the coral's red. Sea whip corals are suspension feeders that thrive in current-exposed positions, making reef wall topography essential to their survival. 4K, vertical, close diver POV. Andaman Sea, Krabi Province, Thailand.
