group, but only for few of the species. Granule densities were compared between light images and SEM images of the same animal and the small observed differences can probably be attributed to uneven distribution of the granules on the disc, rather than to a real difference in accuracy between these methods. Our method of counting granules on digital images resulted in considerably higher numbers than what has been published before. However, published values are not always related to size and as we see in our results, the largest specimens have larger and fewer granules. It is also possible that counts on images are more accurate than counts under the dissecting microscope. In any case, since we used the same method for all specimens, the differences between them are valid and important.
