In contrast,
tightly packed electron dense globules embedded in a matrix of moderate
density have been illustrated in three other caryophyllideans studied
. This character is also visualized in two spathebothriideans
studied. Both types of clusters are reported in Atractolytocestus
huronensis, a caryophyllidean cestode with parthenogenetic type
of reproduction. Moreover, variations in the number, size and arrangement of shell globules within the clusters have been
observed.
