Summary. Based at the results of micromorphological and histochemical investigations it has been concluded that G. crumenifer trematodes have a complex gut system with variant pharynx, developed glands around pharynx and esophagus, intestines with microfibrous epithelium. Morphophysiological and biological peculiarities of G. crumenifer allow them to be adapted to the conditions of their endostation as well as enhance the economic value of this parasite existence in of the definitive host.
