Abstract
Polystoma australis oncomiracidia normally hatch after 10–11 days at 23‡ C and usually remain viable for up to 20 h. Retarded hatching sometimes occurred in normally developed eggs, and oncomiracidia which eventually hatched from these eggs often stopped swimming after a short time, but remained alive. Scanning electron-microscopic examination showed that they had lost their locomotory cilia but not the ciliary cells. This paper reports on the surface structure of the ciliary cells before and after the loss of cilia.
