| Abstract: | The tegument of the paramphistomes Gigantocotyle explanatum, Srivastavaia indica and Gastrothylax crumenifer, basically resembles that described for other digeneans. It is folded into numerous furrows and ridges. Sensory papillae occur on the ridges and are particularly prevalent around the oral opening and acetabulum. Two types of tegumental secretory body are produced in separate tegument cells. Mitochondria are absent from the adult surface syncytium and tegumental cells, suggesting that the tegument is largely protective in function and probably has limited absorptive potential. |
