The intestinal wall, or gastrodermis, is in its structure very similar to that described for other species.

In starved specimens the columnar cells are 60-80 ^ tall and 6-8 ft wide, their sparsely distributed distal cilia extending 12-14 /x. into the intestinal lumen. Subspherical nuclei /j. in diameter are embedded proximally in the cytoplasm, the latter being finely participate and possessing no particular staining affinities. The proximal regions of the columnar cells also contain variable numbers of acidophilic proteinaceous inclusions up to 3-4 /A diameter, and these react positively to the Hess and Pearse technique for endopeptidases.
