安达曼海珊瑚礁上巨扇海葵珊瑚的特写

an sea fan (Annella sp.) in panning close-up on an Andaman Sea coral reef, revealing the intricate branching skeleton and healthy living polyp tissue. Gorgonians grow slowly, adding only a few centimetres per year; large colonies like this one are decades old and irreplaceable on ecological timescales. Their structural complexity provides shelter and foraging habitat for a disproportionate range of reef species relative to their physical footprint.
