To comparatively describe “inner” pharynx armatures in pycnogonids, we bisected proboscides ofAchelia langi(Dohrn, 1881),Anoplodactylus californicusHall, 1912,Ascorhynchus castellioidesStock, 1957,Austrodecus glacialeHodgson, 1907,Callipallene margarita(Gordon, 1932),Colossendeis macerrimaWilson, 1881,Endeis spinosa(Montagu, 1808),Nymphon macronyxSars, 1877,Pallenopsis patagonica(Hoek, 1881),Pantopipettasp.,Pigrogromitus timsanusCalman, 1927, andPycnogonum litorale(Strøm, 1762) and analyzed them with the scanning electron microscope (SEM). Moreover, proboscides were stained with actin green to visualize the muscle arrangement with fluorescence and confocal microscopes (A. langi) and were analyzed with microcomputed X-ray tomography (μCT;Ascorhynchus japonicus). As a result of our observations, sets of characters that vary between taxa are established. These traits include length and width of proboscis, shape and structure of the inner mouth opening, borders and armature of the antimeres, shape and position of denticle arrays and rows, relative length of pharyngeal filter apparatus, and arrangement and structure of the filter bristles. Analyses of these characters indicate a substantial variability on the pantopod’s proboscis inner surface probably as an adaptation to different food sources. Finally, we suggest that the presence of the oyster basket represents a ground pattern character of Pycnogonida.
