Abstract

Ultrastructural organization of the foregut and intestinal caeca was investigated in the developing and mature metacercariae of Diplostomum pseudospathaceum. The features of metamorphosis were found in the development of the metacercarial caeca and oral sucker. It is suggested that metamorphic character of the development of the metacercarial gut may be related to peculiarities of the structural specialization of the free living larvae. In D. pseudospathaceum metacercariae, the functions of the gut are discussed.
