安达曼海礁石上的鲜艳红珊瑚

ed Dendronephthya soft coral covers a deep coral reef wall in the Andaman Sea as a golden damselfish (Amblyglyphidodon aureus) swims above it against open blue water. Dendronephthya corals lack symbiotic algae and instead filter feed on passing microplankton, requiring strong current and low light, conditions typical of deeper Indo-Pacific reef walls where their colour intensifies away from the sun. 4K, wide angle, vertical medium shot, scuba diver POV.
