Teleost fishes are able to live in both fresh water and seawater by means of specialized "ionocytes" in the gill epithelium. Simultaneous immunofluorescence staining of multiple ion-transport proteins revealed morphological variations in ionocytes among teleost species (e.g. rainbow trout, tilapia and zebrafish). Ionocytes possessing apical Na+/H+ exchanger, apical Rh protein, basolateral Na+/K+-ATPase and basolateral Na+/K+/2Cl- cotransporter are common in fishes.

硬骨鱼能够在淡水和海水中生活，依靠鳃上皮中的特化“离子细胞”。多种离子转运蛋白的同时免疫荧光染色揭示了硬骨鱼物种（如虹鳟鱼，罗非鱼和斑马鱼）之间的离子细胞的形态变化。离子细胞具有顶端Na+/H+交换体、顶端Rh蛋白、基底侧Na+/K+-ATP酶和基底侧Na+/K+/2Cl-协同转运体等功能。
