从鱼的视角，在五线笛鲷鱼群中游泳，水下拍摄

diver's POV glides directly into a dense school of five-lined snapper (Lutjanus quinquelineatus) on a shallow Andaman Sea reef, their bright yellow colouration dominating the frame. Their tight schooling behaviour is a defence strategy linked to reef structure, offering protection from predators while allowing the group to manoeuvre through coral cover. This dense fish aggregation is a strong indicator of a structurally intact reef. 4K, wide angle, vertical medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
