SEM micrographs of Dibothriocephalus latus plerocercoids surface (hot fixation). Anterior part of the plerocercoid showing everted scolex with bothria (a). Apical part of scolex; approximate area with observable uncinate spinitriches demarked by white spots (b). Apical region in detail (c, d). Inner surface of bothria (e). Middle part of the plerocercoid (f). Note three different types of microtriches, i.e. uncinate spinitriches (arrow heads), coniform spinitriches (sinuous arrows) and capilliform filitriches (straight arrows) (a–f). Abbreviation: AP, apical pore
