Scanning electron microscopy reveals the presence of ciliated epidermal cells that form halos around canal pores and pit lines of the mechanoreceptive lateral line system in two actinopterygian fish, Polypterus and Acipenser. Transmission electron microscopy shows that the cilia exhibit a typical 9 + 2 microtubule configuration and are not directionally polarized. The function, developmental origin and systematic significance of ciliated epidermal cells in actinopterygian fish are considered.
