Total number of developing lithocytes at all stages in both sides of the epithelial floor in 127 animals of different sizes. The rate of increase of differentiating lithocytes is highest in the youngest animals and slows to reach a plateau range of 8–12 lithocytes with wide scatter in larger animals.

WebLithocytes arise on opposite sides of the epithelial floor along the tentacular plane, that is, at two sites bilateral to the sagittal plane (Figs. 1, 4, 6). The earliest stages appear as single small refractile granules or clusters of granules at the lower edge (basal lamina) of the concave epithelial floor (Fig. 6C). WebWhat is Lithocytes? INTRODUCTION.
