ResumoThe opercular epithelium of Fundulus heteroclitus contains typical gill chloride-secreting cells at the high density of 4 × 10 5 cells per square centimeter. When isolated, mounted as a membrane, and short-circuited, it actively transports chloride ions from the blood side to the seawater side of the preparation. This preparation offers a useful approach to the study of osmoregulation in bony fishes.
