Saginata hatching

The formation of these membranes from the fertilised egg in the Cyclophyllidea is shown in Fig. 7.4. Their structure and formation in Hymenolepis is considered in further detail on p. 179 their histochemistry is shown in Tables 7.3 and 7.6. In considering the functional morphology of eggs, it must be borne in mind that some eggs, such as those of the Pseudophyllidea (e.g. D. latum), hatch in water others hatch in the alimentary canal of invertebrates or vertebrates (e.g. H. diminuta, T. saginata) and one species (H. nana), uniquely, can hatch in both its intermediate (beetle) and definitive (rat) host.
