Abstract
and The digestive tract of isopods has been the subject of extensive studies for over a century (Weber, 1881; Nemec, 1896). Since the introduction of the electron microscope, the digestive tract has been studied by sev- eral workers (Vernon et al., 1974; Coruzzi et al., 1982; Palackal et al., 1984). Thus, we have a description of the hindgut epithelium of a few isopod species. The main feature of the epithelial cells of the hindgut is the numerous membranous infoldings and mi- tochondria between them. This structure suggested some active role for the hindgut in the transport of ions and water (Vernon et al., 1974; Cioffi, 1984). Until now no at- tempt has been made to verify this sugges- tion either physiologically or ultrastruc- turally. With the introduction of new cytochemical techniques it has become pos- sible in recent years to localize the enzymes Figs. 1, 2.
