In the duplex retina of the catfish Clarias batrachus (Linnaeus, 1758), the apical processes of the pigment epithelial cells have been found by transmission electron microscopy to be in intimate contact with the calycal processes around the basal portion of the photoreceptor outer segments. It is hypothesized that the retinal pigment epithelium effectively transports synthesized products and metabolites to the photoreceptor inner segments via the anatomical zone of the apical–calycal processes interface in this species.
