礁鱼颜色变化：幼年蝙蝠鱼皮肤从银色变为黑色

ile Longfin Batfish (Platax teira) appears markedly darker than its schoolmates in this shallow Andaman Sea reef scene, its usual silver body visibly deepening toward black. Many reef fish achieve rapid physiological colour change via chromatophores, cells that expand or contract to alter skin tone, though this specific behaviour is unconfirmed in published Platax teira literature. The rest of the school keeps its typical pale colouring. 4K, wide angle, horizontal medium shot, side view, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
