Abstract

Further evidence defining an active role for the chloride cell in teleost osmoregulation is presented in this study. Gill filaments from salt water adaptedFundulus heteroclitus were fixed in a solution of silver acetate-osmium tetroxide in an attempt to localize chloride at the level of light and electron microscopes. Characteristically, a reaction product in the form of dense granules appeared concentrated and localized near the margin of the chloride cell apical cavity. Selected area electron diffraction patterns obtained from the localized accumulations of reaction product match diffraction patterns from control (known) silver chloride preparations. It should be emphasized that since the reaction product is not concentrated in other regions of the branchial epithelium, these observations strongly support an electrolyte regulating function for the chloride cell.
