Fig. 7 Pharyngeal region, pharynx nuclei, CLSM opti- cal sections. Colors: a–c, e, f: musculature in red/orange, nuclei in blue; d: musculature in blue, nuclei in magenta; nuclei within the orange labelled area/ outline are pharynx nuclei. For some species the outline of the pharynx is further indicated with white dashed lines. a Catanema schiemeri, b Robbea judithae, c Robbea lotti, d Rob- bea weberae, e Cyathorobbea hypermnestra, f Cyathorobbea ruetzleri, g Cyathorobbea agri- cola, h Laxus oneistus.
