Note the amorphous material (arrows) parallel to the oolemma in Figure 19. Bars = variation on the ultrastructural level demonstrated but also that the variation occurs in the female gamete which generally shows little gross morphological variation. The significance of differences in cortical organelle distribution or type of nutrient material in the eggs of Capitella sibling species is not readily apparent but it does not appear to bear any obvious relationship to egg size, cleavage pattern, or type of larval Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
