1978 1979 1980 F A J 1981 FIGURE 4. Mean maximal diameters of oocytes and sperm sacs of Parerythropodium fulvum fulvum at 3 m depth (Fig. 4a) and 30 m depth (Fig. 4b). Ultrastructure of the gonadal surface The oocytes and the sperm sacs of P. f. fulvum are surrounded by a ciliated follicular layer (Fig. 5a, b). These cells are derived from the endodermal epithelium of the septa. Each oocyte or testis is attached to the mesentery by a pedicle of approximately 100 nm (Fig. 5a). The cells of the polyp cavity are covered by cilia of about 20 nm in length. The flagella of the gonadal surface and that of some other endodermal cells are located in small pits. Each flagellum is surrounded at its base by 8 elevated folds of cell surface, in a palisade formation (Fig. 5c), similar to the arrangement described by Mariscal and Bigger (1976) in other octocorals.
