白色的角状海扇上覆盖着红色的海藻，在珊瑚礁上

orgonian sea fans (Subergorgia sp.) undersea, overgrown by red sea plume algae bloom (Asparagopsis taxiformis) across multiple colonies, revealing the scale of algal encroachment on a stressed reef. red sea plume competes for light and space, suppressing recovery and reducing biodiversity. Gorgonians are slow-growing reef engineers; losses at this scale carry lasting structural consequences. Andaman reefs have bleached repeatedly since 1998.
