Morphological polyphenism in this species includes an evolutionary novelty, moveable teeth, which have enabled predatory feeding in this species and others in its family (Diplogastridae). From transmission electron micrographs of serial thin sections through an adult hermaphrodite of\n                    <jats:italic>P. pacificus<\/jats:italic>\n                    , we three\u2010dimensionally reconstructed all epithelial and myoepithelial cells and syncytia, corresponding to 74 nuclei, of its face, mouth, and pharynx. We found that the epithelia that produce the predatory morphology of\n                    <jats:italic>P. pacificus<\/jats:italic>\n                    are identical to\n                    <jats:italic>Caenorhabditis elegans<\/jats:italic>\n                    in the number of cell classes and nuclei. However, differences in cell form, spatial relationships, and nucleus position correlate with gross morphological differences from\n                    <jats:italic>C. elegans<\/jats:italic>\n                    and outgroups. Moreover, we identified fine\u2010structural features, especially in the anteriormost pharyngeal muscles, that underlie the conspicuous, left\u2010right asymmetry that characterizes the\n                    <jats:italic>P. pacificus<\/jats:italic>\n                    feeding apparatus.
